A new type of sanitation vehicle

technical field

The invention relates to a special-purpose vehicle, including the field of municipal sanitation vehicles, in particular to a sanitation vehicle with liquid cleaning, filtering and dust removal functions, including road sweeping vehicles, cleaning and sweeping vehicles, vacuum vehicles, dry sweeping vehicles and other vehicles.

Background technique

Road sweeper is a general term for a class of sanitation vehicles, including vehicle chassis, dustbins, centrifugal fans, suction cups (suction nozzles), suction pipes and accessories, of which the dustbin contains inlets, outlets and tailgates. Its basic working principle is that the suction nozzle is connected to the inlet of the suction pipe, the suction pipe is connected to the inlet of the dustbin, and the outlet of the dustbin is connected to the inlet of the centrifugal fan; the vehicle chassis carries these parts and drives at low speed on the road; Negative pressure is generated at the mouth, and the air and garbage on the road are sucked into the dustbin, and the garbage stays in the dustbin, and the air enters the fan through the dustbin outlet and is discharged into the external environment again. It is dumped at the dumpster through the tailgate of the dumpster.

Sweeping system, low-pressure water mist system (with low-pressure water pump), high-pressure water mist system (with high-pressure water pump), vacuum hood, etc. are all accessories of the road sweeper. Among them, the sweeping system can assist in the collection of garbage and loosen the garbage stuck on the road; the low-pressure water mist system can suppress the dust raised by the sweeper during the work process and prevent dust and garbage from being discharged to the external environment again through the centrifugal fan ; The vacuum hood is used to absorb the dust raised by the sweeping disc during work; the high-pressure water mist flushing system can enhance the road surface cleaning ability and spray dust suppression ability. According to different application occasions, road sweepers have different auxiliary devices, and they have evolved into different variant vehicles. People in the industry usually refer to these subdivided models as road sweepers, washing sweepers, vacuum cleaners, dry sweepers, etc. Road sweeper, wet road sweeper, etc., or according to whether it has a sweeping disc, the vehicle is divided into a suction sweeper or a pure suction sweeper. In addition, road sweepers, sweeping vehicles, etc. will suck a large amount of ground sewage into the garbage bin during operation, so people in the industry often refer to garbage bins as sewage tanks. In this article, garbage bins or sewage tanks are collectively referred to as litter box.

For ease of understanding, the salient features of the above-mentioned subdivided models are first described below. In fact, there are no strict distinctions and unified specifications for these subdivided models, and different manufacturers will freely combine these product features according to actual customer needs.

1) Road sweeper: without a high-pressure water pump; with a low-pressure water pump (usually an electronically controlled diaphragm pump), which cooperates with the nozzle to spray low-pressure water mist on the sweeping plate, suction nozzle, and inside the garbage bin, etc., for spraying and dust reduction; medium and large Road sweepers usually have four sweeping discs, which are arranged in front of the rear wheels of the vehicle, two on each side; usually there is only one suction pipe and one suction nozzle for picking up garbage, and the suction pipe and suction nozzle are arranged in the middle behind the rear wheels .

2) Sweeper: equipped with a high-pressure water pump (usually a plunger pump) and a nozzle to achieve high-pressure and large-flow fine water mist, which can be used for road surface cleaning and spray dust reduction; it also has a low-pressure water pump (usually an electric control diaphragm pump), cooperate with the nozzle to spray low-pressure water mist on the sweeping plate, suction nozzle, inside the garbage bin, etc., for spraying and dust reduction; usually there are two sweeping plates, and the sweeping plates are arranged in front of the rear wheels of the vehicle, one on each side ;Usually there are two suction pipes and a shared suction nozzle for picking up garbage. The suction pipes are arranged in front of the rear wheels, one on each side, and the suction nozzle is arranged in the middle in front of the rear wheels.

3) Vacuum truck: usually without high-pressure water pump; without sweeping plate; usually with two or four suction pipes and a conjoined, shared suction nozzle for sucking garbage; with or without low-pressure water pump, with low-pressure The water pump can cooperate with the nozzle to spray dust on the suction nozzle, inside the dustbin and other places.

4) Dry road sweeper: no high-pressure water pump; with two or four sweeping discs; with two or four suction pipes; there is no nozzle at the sweeping disc, which cannot achieve spray dust reduction; cover it with a vacuum cover Sweep the pan, and cooperate with the suction pipe to suck the dust raised by the pan into the dustbin.

The road sweeper described in this patent generally refers to a class of sanitation municipal vehicles, including all vehicles that use fans for dust suction and road cleaning, especially vacuum cleaners, dry road sweepers, wet road sweepers, and sweepers , road sweeper, etc. The innovative technology described in this patent is a common technology, which is applicable to all the above-mentioned models. For the convenience of description, these subdivided models will be collectively referred to as road sweepers, and will not be described separately.

When the road sweeper is sweeping the road, the centrifugal fan rotates at high speed, and the negative pressure is generated by centrifugal action. The air is sucked by the suction nozzle, and then passes through the suction pipe, dustbin, fan, and finally discharged into the external environment. The garbage near the suction nozzle will be sucked into the suction nozzle together with the air due to the negative pressure and the high-speed air flow, and then reach the dustbin through the suction pipe. Due to the large space of the garbage bin, the air flow rate will suddenly decrease, and the garbage will be decomposed due to the combined effect of gravity separation and air rotation separation; the total mass (such as bricks) and the density is relatively large (such as mud, stones, Nails, glass shards) the garbage will settle at the bottom of the garbage bin first, and the air and unsettled garbage will continue to move towards the outlet of the garbage bin. Because the dustbin is relatively large, the air flow rate is relatively low, and the air stays in the dustbin for a long time. Before the air reaches the dustbin outlet, most of the garbage will settle, but there will still be a small amount of dust and garbage that will pass through the garbage along with the air. The box exits and enters the fan, and is finally discharged into the external environment through the fan outlet to generate secondary air pollution. In order to reduce secondary air pollution as much as possible, that is, to make the air discharged by the fan as clean as possible, some or all of the following dust reduction schemes are usually used on road sweepers:

1: Install the water mist nozzle 1 at the sweeping plate, usually consisting of multiple nozzles. The water mist sprayed by the water mist nozzle 1 wets the ground, so that the floating dust, fine dust and other garbage are fully mixed with the water. Due to the bonding effect of the water, these fine garbage will condense together and become larger pieces of garbage , or small pieces of garbage will stick to larger pieces of garbage. It is not easy to generate dusty phenomenon when sweeping and collecting these garbage. The water sprayed by the water mist nozzle 1 also has the effects of stirring, impacting and high-pressure cleaning on the ground garbage, making it easier for the garbage to be collected by the sweeper and making the ground cleaner.

2: Install the water mist nozzle 2 at the junction of the garbage suction nozzle and the suction pipe or at the ground gap near the rear of the suction nozzle, usually consisting of multiple nozzles. The water mist sprayed by the water mist nozzle 2 mixes with the rubbish inhaled to further bond the rubbish together, or to strengthen the bonding effect, making it easier for the rubbish to settle after entering the dustbin. The water flow ejected from the water mist nozzle 2 also has a stirring and impact effect on the ground garbage, making the garbage more easily sucked by the suction nozzle.

3: Install a water mist nozzle 3 at an appropriate position inside the dustbin (usually a distance behind the outlet of the suction pipe, where the airflow velocity is still high), usually consisting of multiple nozzles. The water mist sprayed by the water mist nozzle 3 mixes with the passing rubbish to promote the settlement of the rubbish again.

4: Install a large-area filter screen or/and air filter cartridge (filter element) before the dustbin exit, so that the air is filtered by the filter screen or/and air filter cartridge before entering the fan, and most of the passing dust and garbage will be Filter out and keep inside the trash. Usually, road sweepers and sweepers have spray dust suppression measures, so only a flat or cubic metal filter (metal plate) with small aperture holes can achieve better filtering effect; Disk, usually there is no spray dust suppression measures or the ability of spray dust suppression equipment is insufficient, and the working environment is even worse (such as steel mills, mines, the amount of dust is very large), so metal filters are usually used for first-level coarse filtration, and then multiple A large cylindrical air filter cartridge for secondary fine filtration.

Whether it is a product that uses a high-pressure and large-flow high-pressure water pump or a low-pressure water pump (such as an electronically controlled diaphragm pump), devices using water mist nozzles can be collectively referred to as spray dust suppression devices.

Usually, after adopting the above scheme, the air reaching the air inlet of the fan is relatively clean, and the air discharged by the fan can meet the environmental sanitation requirements.

From the above analysis, it can be seen that the cleanliness of the air discharged by the fan can be significantly improved by using the above-mentioned spray dust suppression device and filter device, but it has the following obvious disadvantages:

1) The working efficiency of the road sweeper is significantly reduced, and the fuel consumption is increased. One reason is that water needs to be added frequently. Due to the limitation of space and the total weight of the vehicle, it is impossible for the road sweeper to be equipped with a very large water tank. Therefore, when the road sweeper is working, it is not that the garbage bin is full and needs to go to the garbage dump to take out the garbage, but because the water tank is empty and needs to be filled again. to continue working. This directly shortens the continuous and sustainable working time of the road sweeper. Therefore, in actual use, the road sweeper often stops sweeping due to lack of water and goes to the water source to add water, losing a lot of time and fuel consumption.

2) The working efficiency of the road sweeper is significantly reduced. The second reason is the need for frequent drainage. In order to spray and reduce dust, a large amount of water spray is required. A large amount of water enters the garbage bin along with the garbage, and all the garbage (including water) in the garbage bin will increase and increase rapidly. Agitates the water in the litter box, creating waves. If the water is not drained out of the car in time, part of the dirty water and garbage may fall from the suction pipe to the road surface to cause pollution, or be sucked by the fan again and discharged into the external environment again, and this process will quickly damage working devices such as the fan . In order to ensure the safety of the fan and prevent sewage from spilling onto the road, the road sweeper must stop working frequently, park the vehicle on the side of the road, and regularly discharge the sewage in the garbage box out of the vehicle through the sewage discharge ball valve at the tailgate of the garbage box. The whole drainage process usually takes 10 minutes to 30 minutes, and the road sweeper usually drains water 2 to 6 times a day. Among them, the washing and sweeping car with a large water consumption usually needs to be drained every half an hour, which greatly reduces the cleaning time of the road sweeper. work efficiency.

3) The work efficiency of the road sweeper is significantly reduced. The third reason is that the volume of the dustbin has not been fully utilized. The water and garbage used for spray dust suppression are absorbed and stored in a shared garbage bin, which is equivalent to increasing the total garbage volume, especially for washing and sweeping vehicles. When sweeping the road, most of the dustbin inhaled is Water, a small part is real garbage, which causes the volume of the garbage can not be fully utilized. Moreover, due to the high proportion of water in the garbage aqueous solution, high-density solid garbage usually settles in the lower part, while a large amount of dirty water and low-density garbage floats in the upper part and is in a free-flowing state. Under the influence of traffic conditions, it is often necessary to brake and accelerate, which will cause dirty water to flow around in the garbage bin and create waves. In order to ensure that low-density garbage and dirty water will not be lifted by waves and flow along the straw during transportation On the backflow circuit, the design height of the road sweeper loaded with garbage (dirty water) is usually 20 to 60 cm lower than the height of the suction pipe outlet. This means that the effective volume of the dustbin: the total volume of the dustbin is usually only 1:4 or even lower. A very large garbage bin can actually only load a very small amount of garbage due to the above reasons, which leads to a reduction in the single continuous working capacity of the road sweeper.

4) The work efficiency of the road sweeper is significantly reduced. Reason four, water is being used where it is not needed. When the road sweeper is working, it sprays and dedusts all the garbage it absorbs, which is unnecessary. For example, large-mass or high-density garbage such as bricks, coins, screws, etc., after they reach the inside of the garbage bin, even if there is no water attachment, they will quickly settle in the garbage bin and will not be discharged to the outside through the fan again. surroundings. However, the existing road sweepers will also spray these rubbish to reduce dust during work, which naturally consumes more water. If the road sweeper can spray and reduce dust in a more targeted manner during work, that is, on the premise of ensuring the cleanliness of the air discharged by the fan, only the necessary garbage is sprayed for dust reduction, and other garbage is not sprayed for dust reduction. The water consumption will be reduced, so the road sweeper with the same capacity clean water tank can continue to work for a longer period of time, thereby improving work efficiency.

5) The road sweeper consumes a lot of water and wastes water resources. One reason is the high water consumption. In order to ensure the effect of dust reduction, a lot of water must be sprayed to achieve the purpose, so road sweepers need to waste a lot of urban water every day. This is not in line with the concept of environmental protection in the era of global water shortage. At Nozzle 2 and Nozzle 3, the fine water mist used for spraying dust reduction and the passing garbage need to be fully contacted to achieve a good dust reduction effect, but the high-speed airflow here has a negative impact on the full contact between the two, and this should be improved If there is no problem, it is necessary to increase the water supply volume and water supply pressure, which in turn brings about the problems of large water consumption, more frequent sewage discharge and high fuel consumption. Therefore, the design of this road sweeper can only balance the advantages and disadvantages as much as possible and cannot completely solve the problem.

6) It consumes a lot of water and wastes water resources. The second reason is that water cannot be reused. Every time the garbage is dumped, all the garbage and water in the garbage bin will be poured out. This water cannot be reused for road sweeping and dust reduction, which is a waste of water resources. In order to solve this problem, some road sweeper manufacturers try to install sewage recovery and reuse devices in the road sweeper to reduce the overall consumption of water. However, these devices take up a large amount of internal volume of the dustbin, and significantly increase vehicle manufacturing costs and post-use maintenance costs.

7) The road sweeper consumes a lot of fuel. The first reason is that the total mass of the car is large. In order to ensure the spray dust reduction effect and the continuous working time of the vehicle, the road sweeper needs to be equipped with a large water tank and fill up the water before starting to work, which results in a heavy vehicle. Heavy-duty vehicles shuttle back and forth between the vehicle parking place-road sweeping place-garbage dumping place, which inevitably requires a lot of fuel consumption.

8) The road sweeper (washing and sweeping car) consumes a lot of fuel. The second reason is that the high-pressure water pump has a large power. For cleaning vehicles, with the help of high-pressure and high-flow high-pressure water pumps, the above-mentioned nozzles can achieve better spray and dust reduction effects. However, the driving power of the high-pressure water pump is very large, usually around 25 to 40kw, which needs to be powered by the vehicle itself, which will naturally significantly increase the fuel consumption of the sweeper.

9) The road sweeper has high fuel consumption and low work efficiency. The third reason is that the air filter cartridge increases the air pressure difference between the two ends of the fan. Vacuum trucks are mainly used to absorb fine dust, such as in mines or steel mills. Due to the high dust content in the garbage in this occasion, in order to ensure that the air discharged by the fan is clean enough, it is necessary to install multiple large-volume air filter cartridges at the front end of the dustbin connected to the fan inlet to filter the air flowing into the fan. . But because there is too much dust in the garbage, the filter element will be blocked quickly, and the blocked filter element will significantly increase the air pressure difference between the two ends of the fan, and the load of the fan will increase, thus consuming more fuel. In addition, in order to ensure the normal operation of the vacuuming vehicle, the vacuuming vehicle needs to be cleaned frequently or replace these large air filter cartridges, thereby reducing the work efficiency and increasing the manufacturing and use costs of the vehicle.

10) Bring secondary environmental pollution. There is usually a sewage valve on the tailgate of the garbage bin. When the sewage in the garbage bin is full and needs to be drained, some road sweeper drivers directly discharge the sewage to the side of the road through the sewage valve in order to save trouble, causing secondary environmental pollution.

11) The idle waste of road sweeper equipment in winter is serious. The reason is that it cannot work normally in the northern weather below 0 degrees. The water in the water tank of the road sweeper is used for spray dust reduction or high-pressure cleaning. Part of the sprayed water is directly left on the road, and part of the water is sucked into the garbage bin and then dumped at the roadside or garbage station, that is, all water tanks The water in the tank is consumed once and cannot be reused. If there is no dust-reducing effect of water spray, the work of road sweepers in the traditional sense will cause dust to fly everywhere, and a large amount of dry dust sucked into the dustbin will be sucked by the fan and discharged into the external environment again, resulting in secondary pollution. Due to the limitation of cost and environmental discharge, the water in the water tank is taken from tap water, industrial water, or fire hydrant water supply. It is impossible to add a liquid medium that can lower the freezing point like antifreeze to ensure that the road sweeper is below 0 degrees. Spray dust during road sweeping in winter. Therefore, road sweepers with water spray dust suppression cannot be used in northern winter. Existing vehicles used for road cleaning in winter in the north are all dry-type road sweepers without clean water tanks and cannot be sprayed to reduce dust. After the garbage is sucked into the dustbin, a large amount of dust will be ejected again with the fan, forming secondary Secondary environmental pollution, this problem has not been well resolved.

12) Bring additional workload, difficulty and cost to the post-processing of garbage. Since the dumped garbage is accompanied by a large amount of sewage, this brings additional workload and cost to subsequent sewage collection and treatment, garbage compression, and centralized garbage transportation.

In a word, the invention provides a kind of novel sanitation vehicle, has the following advantages:

1. The air discharged by the fan of the sanitation vehicle is cleaner and more environmentally friendly, avoiding secondary dust. The dust removal effect of the liquid cleaning filter dust removal device is excellent, and the air cleanliness after passing through the device can be much higher than the original solution, so the air discharged by the fan of the sanitation vehicle adopting the solution of the present invention is cleaner and more environmentally friendly, avoiding secondary dust.

2. Save water resources. With the help of the liquid cleaning, filtering and dust removal device, the air discharged by the fan of the sanitation vehicle can be very clean. Compared with the original technical solution, under the premise of the same cleanliness of the air discharged by the fan, if the same road surface is swept, it only needs to use less water. The same effect can be achieved by spraying dust.

3. Significantly reduce vehicle energy consumption and exhaust emissions. The sanitation vehicle of the present invention does not need to frequently go to the water filling point to add water, so the energy consumption corresponding to the water filling distance is significantly reduced; in addition, the sanitation vehicle consumes less water, and a smaller clean water tank can also be used, thereby reducing the total weight of the vehicle. Reduce vehicle energy consumption and exhaust emissions.

4. Strong suction, long cruising range, significantly improving the working efficiency of the vehicle. The vacuum truck adopting this solution no longer needs to install multiple large air filter cartridges, and there is no risk of excessive dust clogging the filter cartridges, so the pressure loss of fan suction is significantly reduced, and the suction nozzle is strong, which can completely solve the problem of existing vacuum cleaners. The disadvantage of insufficient suction, the vehicle can drive faster on the same dusty road under the premise of ensuring the dust suction effect, thereby improving work efficiency. In addition, because the water-saving effect of the solution of the present invention is obvious, the sanitation vehicle does not need to stop frequently to add water to the clean water tank during work, and can clean a longer road surface in the same time, further improving work efficiency.

5. Reduce the cost of vehicle manufacturing and use, save time and effort for operators, and provide a comfortable working environment. Reducing water consumption and reducing vehicle energy consumption can reduce the cost of using the vehicle. In addition, for the vacuum vehicle, the vacuum vehicle adopting the solution of the present invention does not need the air filter cartridge and the corresponding compressed air blower for dust removal of the filter cartridge. The dust system reduces the corresponding vehicle manufacturing cost and consumable cost; the operator does not need to spend a lot of time wearing a dust mask and cleaning the filter cartridge manually with an air gun, so the operator can save a lot of time and the working environment is significantly improved.

6. It can ensure the normal work of sanitation vehicles in winter. The liquid in the liquid cleaning, filtering and dedusting device can be a special liquid with a freezing point below 0 degrees, or even minus 30 degrees. Since the liquid does not need to be replaced frequently, the cost of use is very low. The sanitation vehicles (such as dry sweepers) that adopt this scheme Road vehicles, dry vacuum vehicles) can still achieve good working results without water spray dust suppression system, so it can be used normally in winter in northern China.

7. Reduce the random dumping of sewage and be more environmentally friendly. Because the sanitation vehicle of this innovative solution consumes less water, the same trash can can continue to work for a longer period of time. Before the trash can is full, the driver may have completed the task of cleaning the road, and will not dump sewage on the side of the road at will. It is to directly pull all the sewage and garbage back to the garbage station for treatment, thereby reducing the secondary pollution to the road. Especially for sweeping cars with a large water consumption, assuming that the sweeping cars in the original plan will dump sewage to the roadside four times a day, if the innovative plan is adopted, due to the significant reduction in water consumption, the sweeping cars will dump sewage to the roadside four times a day. There may be only one or two side dumping of sewage, thereby reducing secondary pollution to the road.

Referring to Fig. 1 to Fig. 21, the specific embodiment of the present invention is further described.

The purpose of the present invention is to provide a new type of sanitation vehicle, which can make the air discharged by the fan of the sanitation vehicle cleaner and more environmentally friendly, avoid secondary dust; save water resources; significantly reduce vehicle energy consumption and exhaust emissions; strong suction, long cruising range, significantly Improve the working efficiency of vehicles; reduce the cost of vehicle manufacturing and use, save time and effort for operators, and provide a comfortable working environment; ensure that sanitation vehicles can work normally in winter; reduce random dumping of sewage and be more environmentally friendly.

In order to achieve the above object, the present invention adopts following technical scheme:

A new type of sanitation vehicle, comprising a vehicle chassis 2, a dustbin 3, a blower fan 4, a suction nozzle 5, a suction pipe 6, and a dust removal partition 712, which is characterized in that the dust removal partition 712 divides the dustbin 3 into two types of compartments, respectively It is called the intake bin 705 and the outlet bin 706, wherein the inlet bin 705 is connected with the outlet of the suction pipe 6, the outlet bin 706 is connected with the inlet of the fan 4, and there is dust removal liquid 9 inside the dustbin 3, the inlet bin 705 and the outlet bin 706 It is connected under the dust removal partition 712, and a certain amount of dust removal liquid 9 is pre-installed inside the dustbin 3, and the dust removal liquid 9 is located at the connection; the fan 4 works to generate negative pressure, so that the garbage enters the suction pipe 6 from the suction nozzle 5, and then enters the garbage In the air intake compartment 705 of box 3, the air flow passes through the dust removal partition 712 or bypasses the dust removal partition 712 under negative pressure and then flows into the air outlet compartment 706. During this process, garbage and dust are filtered and dissolved into the dust removal liquid In 9, the clean gas coming out of the dedusting liquid 9 is discharged through the fan 4, the dustbin 3, the fan 4, the suction nozzle 5, the suction pipe 6, and the dust removal partition 712 are all arranged on the vehicle chassis 2, and the dust removal partition 712 is arranged on the garbage Inside the box 3, the vehicle chassis 2 is used to drive the whole vehicle to move.

Viewed from a top view, the dust-removing partition 712 is single-sided, multi-sided or ring-shaped; the periphery of the side plates of the dust-removing partition 712 is curved, folded or circuitously arranged. Dust removal partition 712 is made into this type of shape, and its purpose is exactly to increase the area of airflow passage as much as possible, reduces the average velocity of airflow; Increase the perimeter of airflow passage as far as possible, allows airflow to enter dedusting liquid 9 with thin layer as far as possible, increases The contact area between the air and the dedusting liquid 9 improves the effect of cleaning, filtering and dedusting, reduces the relative speed difference between the air and the dedusting liquid 9, reduces the generation of spray and mist, reduces the kinetic energy of the dedusting liquid 9, and reduces the loss of air energy consumption, that is , improve the suction of the nozzle and save vehicle fuel.

The outlet of the suction pipe 6 is inside the ring surrounded by the dust removal partition 712 , or the suction pipe 6 is inside the ring surrounded by the dust removal partition 712 and the side wall of the dustbin 3 .

Define the front direction as the front, the blower fan 4 is in front of the dustbin 3, the air intake chamber 705 is in front of the air outlet chamber 706, and the air outlet chamber 706 communicates with the tailgate of the dustbin 3.

The lower side of the air inlet of the fan 4 is provided with a liquid baffle 717 . The shape of the liquid baffle 717 is usually a plane, and it can also be low in the middle and high on both sides, which is conducive to diverting the splashed liquid spray and reducing the probability of the spray being sucked by the fan.

The lower section of the dust removal partition 712 is provided with a gas crushing channel 7121, so that the air can enter the dust removal liquid after being crushed. The gas crushing channel 7121 increases the surface area where the gas and the dust removal liquid 9 are in contact to achieve a better dust removal effect. The channel 7121 can adopt small holes or triangular gaps to break the channel; the initial liquid level of the dust removal liquid 9 is not lower than 1 meter from the lower edge of the dust removal partition 712; The liquid level of the dust removal liquid 9 in the air outlet chamber 706 is higher than or equal to the lower edge of the dust removal partition 712 .

The initial liquid level of the dust removal liquid 9 is slightly higher than the lower edge of the dust removal partition by 5 centimeters.

The dustbin 3 communicates with the vehicle-mounted clean water tank 1 through a pipeline, and the pipeline is provided with a switch valve or a water pump with a cut-off function. The usual process of adding water is to connect the water pipe to the interface of the clean water tank, add water to the clean water tank, open the switch valve at the right time, let the water flow from the clean water tank into the garbage bin, and close the switch valve at the right time to ensure that the dust removal liquid in the garbage tank The height is right. If the water pump is used, the idea is similar, and the same effect can be achieved by turning on and off the water pump at the appropriate time.

The dedusting liquid 9 is preferably clear water, and additives are added to improve the performance of the liquid when necessary. Part or all of the dedusting liquid 9 is clear water, in which antifreeze can be added to lower the freezing point of water, so that the dedusting liquid 9 can maintain a liquid state in an environment below 0 degrees without condensing and solidifying; the dedusting liquid 9 can also contain sterilizing Foaming agent, thereby helping the air bubbles to break up and separate out from the dedusting liquid 9 quickly.

After the air flow comes out from the outlet of the suction pipe 6, it first enters the dust removal liquid 9 downwards, passes through the dust removal partition 712 through the gas crushing channel or bypasses the dust removal partition 712 from below, and then reaches the fan inlet 401 upwards.

The outlet of the suction pipe 6 is in the middle and upper part of the dustbin 3. When the sanitation vehicle is operating normally, the outlet position of the suction pipe 6 is higher than the initial liquid level of the dust removal liquid 9 in the dustbin 3, and the outlet direction of the suction pipe 6 is upward or obliquely upward or horizontal. , the dustbin 3 can be dumped backwards, forwards or sideways relative to the vehicle chassis 2; the outlet of the suction pipe 6 is the highest point of the whole suction pipe 6; Distributed on the ground; during operation, the suction nozzle 5 is fixed relative to the dustbin 3 by the suspension system, and the suction nozzle 5 is below the height of the bottom surface of the dustbin 3;

The suction nozzle 5 only moves forward with the vehicle relative to the ground to absorb garbage, and occasionally moves backward with the vehicle when reversing, and will not move left or right relative to the garbage bin;

The suction pipe 6 enters vertically upwards from the bottom of the dustbin 3, or enters obliquely upwards into the dustbin 3, or enters obliquely upwards from the side of the dustbin 3 near the bottom; or enters the garbage horizontally from the side of the dustbin 3 Inside box 3.

The dustbin 3 is provided with an inspection port and a liquid level gauge, and the inside of the dustbin 3 is provided with a cleaning nozzle, and the water ejected from the nozzle can clean the inside of the dustbin 3, and the bottom of the dustbin 3 is provided with a sewage outlet 21.

Described dedusting fluid 7 selects clear water for use when the ambient temperature is above 0 degrees, and selects non-freezing antifreeze for use when the ambient temperature is below 0 degrees.

Fig. 1 is a comparison between the prior art scheme of the air flow route and the technical scheme of the present invention when the sanitation vehicle is in operation. The air coming out of the dustbin of the existing sanitation vehicle is directly discharged through the fan, but in the present invention, the air, garbage and dust coming out from the outlet of the suction pipe all enter the dust removal liquid in the dustbin to remove dust, and the air after being cleaned, filtered and dust removed Exhausted by a fan, so the exhausted air is cleaner.
