Description

Concrete delivery pipe cleaning method and device technical field

The invention relates to the field of equipment cleaning, in particular to a method and device for cleaning a concrete delivery pipe.

Background technique

When the concrete is transported through the concrete delivery pipe, it is easy to cause the concrete to harden and block the delivery pipeline. When the transported concrete is "rapid hardening concrete", the setting time is shorter than that of ordinary concrete, and the clogging problem is more significant. In addition to scrapping the pipeline, the clogging of concrete pipes also causes material waste and even damages the concrete pump.

The prior art adopts the method of manual cleaning after periodic manual cleaning/clogging, which often cannot be cleaned accurately before the clogging occurs. If the cleaning time is too early, the operation of the conveying pipe will be frequently interrupted, which generally reduces the effective use time of the conveying pipe; if the cleaning time is too late, irreversible hardening of the concrete in the pipe may occur, resulting in blockage.

The above problems are more significant in the process of large-scale concrete production. When producing concrete on a large scale, it is required that the concrete conveying pipes continue to operate for as long as possible without clogging.

There is a need for a better concrete delivery pipe cleaning method and device to solve the above problems.

Detailed ways

The technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the implementations of this specification, not all of them. Based on the implementations in this specification, all other implementations obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

See Figure 1. A flow chart of a cleaning method for a concrete delivery pipe provided in this manual. The method may include the following steps.

In this embodiment, the object performing the method for cleaning the concrete delivery pipe may be an electronic device with a logic operation function. The electronic device may be a server or a client. The electronic device may be a desktop computer, a tablet computer, a notebook computer, a workstation, and the like. Certainly, the object performing the method for cleaning the concrete delivery pipe is not limited to the above-mentioned electronic equipment with a certain entity, and it can also be software running in the above-mentioned electronic equipment.

Step S10: at least based on the acquired concrete pressure in the concrete delivery pipe and the concrete flow rate in the concrete delivery pipe, determine the smoothness characteristic value of the concrete delivery pipe; the smoothness characteristic value is used to represent the blockage of the delivery pipe degree.

In this embodiment, the concrete conveying pipe is used for conveying concrete. Concrete can stick to the inner wall of the delivery pipe, causing blockage of the delivery pipe.

In this embodiment, the concrete delivery pipe may have attribute values of multiple dimensions. Specifically, for example, attribute values such as inner and outer diameters, materials, lengths, and inclination angles of the delivery pipe. Another example is the concrete type, flow rate, pressure, temperature, etc. in the delivery pipe.

In this embodiment, the concrete delivery pipe may be blocked due to concrete residue generated during use. The unimpeded characteristic value is used to characterize the blockage degree of the concrete delivery pipe. Specifically, the unimpeded characteristic value includes at least two factors: the concrete pressure in the delivery pipe and the concrete flow rate in the delivery pipe. In one embodiment, the unblocked characteristic value=flow rate/pressure. Certainly, the smoothness characteristic value may also be in other representation forms, specifically, for example, y=f(v, p, T, t). Among them, y represents the unimpeded characteristic value, v represents the flow velocity, p represents the pressure, T represents the temperature, t represents the time length, and f represents the functional relationship. In a preferred embodiment, the concrete pressure is the pressure at the inlet of the concrete delivery pipe, and the concrete flow rate is the flow velocity at the outlet of the concrete delivery pipe.

Step S12: Determine a cleaning evaluation value based at least on the unimpeded characteristic value; the cleaning evaluation value is used to indicate the degree of cleaning of the concrete delivery pipe; when the cleaning evaluation value is less than or equal to a preset cleaning threshold and When the time dimension satisfies the specified duration, a cleaning instruction is sent to the cleaning mechanism for the cleaning mechanism to clean the conveying pipe.

In this embodiment, the cleaning evaluation value may be determined based on the smoothness characteristic value through a function. Specifically, for example, cleaning evaluation value=the smoothness characteristic value/preset smoothness value, wherein the preset smoothness value is at least associated with the characteristics of the concrete conveyed by the conveying pipe. Of course, the cleaning evaluation value can also be expressed by other functional relations, which will not be described in detail here.

In this embodiment, the preset unimpeded value is a preset standard value used to indicate that the state of the delivery pipe transporting the working medium is normal and no cleaning of the delivery pipe is required. Specifically, the preset unimpeded value may be the flow velocity/pressure value when the concrete delivery pipe is first bought and put into use, of course, it may also be y1=f1(v, p, T, t, X). y1 represents the preset unimpeded value, v represents the flow velocity of the concrete conveying pipe when it is first bought and put into use, p represents the pressure of the concrete conveying pipe when it is first purchased and put into use, and T represents the concrete conveying pipe when it is just purchased The temperature when it was put into use when it came, t represents the time when the concrete delivery pipe was put into use when it was just bought, and X represents the concrete type.

In this embodiment, the cleaning mechanism may refer to an external mechanism for cleaning the concrete delivery pipe. The cleaning mechanism may be a simple alarm mechanism, which is used to send an alarm sound to remind workers to clean the delivery pipe. Of course, the cleaning mechanism can also be a pneumatic compression rod for cleaning the concrete delivery pipe. In a preferred embodiment, the cleaning mechanism may be a self-cleaning mechanism equipped with an elastic cleaning body, and the concrete residue in the delivery pipe may be cleaned by the elastic cleaning body.

In this embodiment, the preset cleaning threshold is used for comparison with the cleaning evaluation value, and when the cleaning evaluation value is less than or equal to the preset cleaning threshold and the time dimension satisfies a specified duration, a cleaning message is sent to the cleaning mechanism. instructions for the cleaning mechanism to clean the delivery tube. When the cleaning evaluation value is greater than a preset cleaning threshold, the concrete pump maintains normal operation.

In a preferred embodiment, the cleaning evaluation value=the unimpeded characteristic value/the preset unimpeded value, the preset cleaning threshold is 0.85, and the specified duration is 1 minute. In this case, the cleaning effect is better, and it will not cause premature cleaning and too late cleaning.

In this embodiment, when the cleaning evaluation value is less than or equal to the preset cleaning threshold and the time dimension meets the specified duration, a cleaning instruction is sent to the cleaning mechanism, and a braking instruction is also sent to the concrete pump to stop the concrete delivery. After it is determined that the cleaning is completed, it also includes sending an instruction to release the brake to the concrete pump.

Step S14: Correcting the cleaning evaluation value at least according to the cleaned concrete.

In this embodiment, the cleaning evaluation value may be corrected based on manually observing the cleaned concrete, or based on the concrete received by the concrete recoverer. Specifically, the parameters of the cleaned concrete may include parameters in multiple dimensions. For example, the total mass of the cleaned concrete, the number of concrete blocks in the cleaned concrete whose volume is larger than the preset volume, the mass of the concrete whose volume is larger than the preset volume in the cleaned concrete, and the like. The parameters of the cleaned concrete are matched with the thresholds of the corresponding dimensions to obtain the characterization values of each dimension; wherein the thresholds are used to represent the parameters of the corresponding dimensions when it is valuable to clean the concrete pipe; based on each The representative value of the dimension is used to modify the cleaning evaluation value. Wherein, correcting the cleaning evaluation value may be to multiply the cleaning evaluation value before correction by a correction coefficient (which may be greater than 1 or less than 1) to obtain a corrected cleaning evaluation value. It may be the cleanliness evaluation value before correction plus a correction coefficient (can be positive or negative) to obtain the cleanliness evaluation value after correction, etc.

In this embodiment, the cleaning evaluation value is corrected based on the characteristic value of each dimension. Specifically, for example, when the total mass of the cleaned concrete is greater than the first preset mass, the corrected cleaning evaluation value is obtained according to the first correction function, wherein the corrected cleaning evaluation value is smaller than the corresponding pre-corrected The cleaning rating. For example, the cleaning evaluation value obtained before correction is 0.84, the preset cleaning threshold is 0.85, the first preset mass is 30kg, and the total mass of cleaned concrete at this time is 50kg. It means that the cleaning is late and can be done in advance, so the preset correction coefficient is 0.02, and the correction coefficient is subtracted each time the cleaning evaluation value is obtained after the concrete delivery pipe to obtain the corrected cleaning evaluation value, so that the cleaning evaluation value in the next cleaning The timing could be more reasonable.

For another example, the cleaning evaluation value before correction is 0.84, the preset cleaning threshold is 0.85, the first preset mass is 30kg, and the total mass of cleaned concrete is 50kg. It means that the cleaning is late, and it can be advanced. The preset correction coefficient a is a function of the total mass of the cleaned concrete and the first preset mass. After the concrete delivery pipe is obtained, the correction coefficient a is multiplied each time the cleaning evaluation value is obtained. , to obtain the corrected cleaning evaluation value, and the cycle iteration can make the corrected cleaning evaluation value also converge to the preset cleaning threshold when the total mass of the cleaned concrete is equal to the first preset quality.

The same is true for the dimension corresponding to the number of concrete blocks whose concrete block volume is larger than the preset volume in the cleaned concrete. No specific details are given here. Of course, multiple dimensions can also be considered at the same time, the characterization values of multiple dimensions form a characterization vector, and the cleaning evaluation value is corrected according to the characterization vector.

Through the above embodiment, at least based on the concrete pressure in the concrete delivery pipe and the concrete flow rate in the concrete delivery pipe, the unimpeded characteristic value can be determined, and the cleaning evaluation value can be further determined to determine whether the concrete delivery pipe needs to be cleaned. When the cleaning evaluation value is less than or equal to a preset cleaning threshold and the time dimension satisfies a specified duration, a cleaning instruction is sent to the cleaning mechanism for the cleaning mechanism to clean the conveying pipe. The above embodiment also includes a feedback mechanism, at least according to the cleaned concrete, to modify the cleaning evaluation value. When the concrete delivery pipe is used subsequently, feedback can be given according to the concrete cleaned each time, and the cleaning evaluation value can be continuously corrected, so that the concrete delivery pipe can be cleaned each time neither too early nor too late, and the concrete pump and concrete delivery can be extended. Tube useful life

Please refer to Figure 2, which is a specific implementation scenario of this application. According to the above embodiment, the clogging state is automatically detected. When the conveying pipe starts to be clogged, the processing center generates a "brake" command, and the concrete pump is ordered to stop running immediately through the radio frequency transceiver, prolonging the life of the machine. When the concrete pump stops, a "pumping has stopped" signal is sent to the central processing center via a radio frequency transceiver. After the central processing unit receives the signal of "pumping has stopped", it sends a command of "start cleaning" to the delivery pipe cleaning device through the radio frequency transceiver. After the conveying pipe cleaning device receives the "start cleaning" command, it starts the self-cleaning program, automatically connects to the inlet of the conveying pipe, and starts cleaning. After the cleaning is completed, the self-cleaning device for the delivery tube disconnects the connection with the delivery tube, and sends a "cleaning completed" signal to the central processing unit through a radio frequency transceiver. After the central processing unit receives the signal of "cleaning completed" after receiving the command, it sends the command of "release brake" to the concrete pump braking device, so that the concrete pump will automatically restart when the delivery pipe is unblocked.

The concrete delivery pipe cleaning method in this implementation scenario can prevent the ineffective operation of the upstream equipment concrete pump due to the blockage of the concrete delivery pipe, reduce energy waste in the short term, and prolong the machine life in the long term. Avoid concrete overflow caused by continuous pumping when the delivery pipe is blocked in the concrete pump room, and avoid material waste and manual cleaning costs after overflow. Fully automatic workflow, from stopping pumping-starting self-cleaning-restarting pumping to achieve the effect of "no manual intervention in the whole process", saving time and improving overall operational efficiency. Detect the risk of pipeline blockage in time, prevent irreversible internal hardening of the pipeline caused by too late cleaning, and improve the service life of the pipeline.

In one embodiment, in the step of correcting the cleaning evaluation value, the parameters of the cleaned concrete at least include parameters in the following dimensions: the total mass of the cleaned concrete; the volume of concrete blocks in the cleaned concrete is greater than the preset volume number of concrete blocks.

In this embodiment, no matter what method is used to clean the concrete delivery pipe, the cleaned concrete has a certain quality, and the cleaned concrete can be powdery or lumpy. This embodiment considers the total mass of the cleaned concrete and the number of concrete blocks whose volume is larger than the preset volume in the cleaned concrete. The above two dimensions can better reflect the timing of cleaning to a certain extent. Correct the cleaning evaluation value more scientifically.

In one embodiment, the unimpeded characteristic value is determined according to the following function: unimpeded characteristic value=concrete flow rate/concrete pressure; wherein, the concrete pressure is the pressure at the entrance of the concrete delivery pipe, and the concrete flow rate is the concrete Velocity at the outlet of the duct. The above-mentioned implementation method is simple to calculate, and the calculation result can be better used as the unimpeded characteristic value.

In one embodiment, the cleaning evaluation value is determined according to the following function: cleaning evaluation value=the smoothness characteristic value/preset smoothness value, wherein the preset smoothness value is at least related to the characteristics of the concrete conveyed by the delivery pipe couplet.

In this embodiment, the preset unimpeded value is a preset standard value used to indicate that the state of the delivery pipe transporting the working medium is normal and no cleaning of the delivery pipe is required. Specifically, the preset unimpeded value may be the flow velocity/pressure value when the concrete delivery pipe is first bought and put into use, of course, it may also be y1=f1(v, p, T, t, X). y1 represents the preset unimpeded value, v represents the flow velocity of the concrete conveying pipe when it is first bought and put into use, p represents the pressure of the concrete conveying pipe when it is first purchased and put into use, and T represents the concrete conveying pipe when it is just purchased The temperature when it was put into use when it came, t represents the time when the concrete delivery pipe was put into use when it was just bought, and X represents the concrete type.

The above-mentioned implementation method is simple to calculate, and the calculation result can be better used as the unimpeded characteristic value.

In one embodiment, the preset cleaning threshold is 0.85, and the specified duration is 1 minute.

Through a lot of experiments and experiences, when the preset cleaning threshold is 0.85 and the specified duration is 1 minute, it is most appropriate to send a cleaning instruction to the cleaning mechanism.

In one embodiment, the parameter of the cleaned concrete is matched with the threshold of the corresponding dimension to obtain the characteristic value of each dimension; wherein, the threshold is used to indicate that the corresponding dimension is valuable for cleaning the concrete pipe parameters; modifying the cleaning evaluation value based on the characteristic value of each dimension.

In this embodiment, the parameters of the cleaned concrete may include parameters in multiple dimensions. For example, the total mass of the cleaned concrete, the number of concrete blocks in the cleaned concrete whose volume is larger than the preset volume, the mass of the concrete whose volume is larger than the preset volume in the cleaned concrete, and the like. Each dimension can have a corresponding threshold value, which is used to represent the parameter of the corresponding dimension when it is worthwhile to clean the concrete pipe. Wherein, correcting the cleaning evaluation value may be to multiply the cleaning evaluation value before correction by a correction coefficient (which may be greater than 1 or less than 1) to obtain a corrected cleaning evaluation value. It may be the cleanliness evaluation value before correction plus a correction coefficient (can be positive or negative) to obtain the cleanliness evaluation value after correction, etc.

In this embodiment, the cleaning evaluation value is corrected based on the characteristic value of each dimension. Specifically, for example, when the total mass of the cleaned concrete is greater than the first preset mass, the corrected cleaning evaluation value is obtained according to the first correction function, wherein the corrected cleaning evaluation value is smaller than the corresponding pre-corrected The cleaning rating. For example, the cleaning evaluation value obtained before correction is 0.84, the preset cleaning threshold is 0.85, the first preset mass is 30kg, and the total mass of cleaned concrete at this time is 50kg. It means that the cleaning is late and can be done in advance, so the preset correction coefficient is 0.02, and the correction coefficient is subtracted each time the cleaning evaluation value is obtained after the concrete delivery pipe to obtain the corrected cleaning evaluation value, so that the cleaning evaluation value in the next cleaning The timing could be more reasonable.

For another example, the cleaning evaluation value before correction is 0.84, the preset cleaning threshold is 0.85, the first preset mass is 30kg, and the total mass of cleaned concrete is 50kg. It means that the cleaning is late, and it can be advanced. The preset correction coefficient a is a function of the total mass of the cleaned concrete and the first preset mass. After the concrete delivery pipe is obtained, the correction coefficient a is multiplied each time the cleaning evaluation value is obtained. , to obtain the corrected cleaning evaluation value, and the cycle iteration can make the corrected cleaning evaluation value also converge to the preset cleaning threshold when the total mass of the cleaned concrete is equal to the first preset quality.

The same is true for the dimension corresponding to the number of concrete blocks whose concrete block volume is larger than the preset volume in the cleaned concrete. No specific details are given here. Of course, multiple dimensions can also be considered at the same time, the characterization values of multiple dimensions form a characterization vector, and the cleaning evaluation value is corrected according to the characterization vector.

In one embodiment, when the cleaning evaluation value is less than or equal to the preset cleaning threshold and the time dimension satisfies a specified duration, it also includes sending a brake instruction to the concrete pump; brake command.
