Description

The invention relates to the field of urban economy, and in particular to devices for melting snow during the winter maintenance of streets and urban areas. The invention can be used both for the needs of the city - cleaning the roadway, and for local cleaning of the territories of transport and construction enterprises, enterprises in the sphere of consumer services (shops, gas stations, restaurants, various pavilions and kiosks, etc.).

Snow melters are divided into two groups: stationary, containing baths for receiving and melting snow mass, devices for heating the water located in the bath with combustion products of liquid or gaseous fuels, a pump for taking water from the bath and feeding it through nozzles for irrigation of snow mass, a sewage system for removal melt water from the bathtubs.

U.S. Patent No. 5235762, IPC: E01H 5/10, 1995. Patent of the Russian Federation No. 2233950, E03F 5/02, 2004.

There are snow melters for local cleaning of snow at the place of its precipitation with the help of a heat source passing under the pavement. Patent of the Russian Federation No. 2096554, IPC: Е01Н 5/10, 1997

All stationary snow melters contain a snow melting intensifier made in the form of infrared emitters (patent of the Russian Federation No. 2226591, IPC: Е01Н 5/10, 2004) or a collector with irrigation pipes (patent of the Russian Federation No. 2237136, IPC: Е01Н 5/10, 2004).

All the above installations are cumbersome, laborious for construction, occupy large areas, so they should be built outside the city. Consequently, transportation costs are required for the collection and delivery of snow.

Another solution to the problem of eliminating snow is local snow melts (USSR author's certificate No. 1511309, IPC: Е01Н 5/10, 1989; USSR author's certificate No. 1565937, IPC: Е01Н 5/10, 1989), snow melting machines installed on chassis for transporting snow due to physical effort, based on a trailer (USSR author's certificate No. 1323632, IPC: Е01Н 5/10, 1987) and mobile snow melters (US patent No. 4071966, IPC: Е01Н 5/10, 1978; USSR copyright certificate No. 1534132, IPC: Е01Н 5/10/1990, USSR copyright certificate No. 1771497, IPC: ЕН 5/10, 1992, US patent No. 5787613, IPC: Е01Н 5 / 10, 1998, patent of the Russian Federation No. 2195526, IPC: Е01Н 5/10, 2002).

The coolants in these snow melters are exhaust gases, pre-filled hot water, gas burners. Devices with pre-filled hot water have a low efficiency because The cooled water is drained and refilled with hot water. Devices with gas burners are explosive, unstable due to clogging of the burners when they get foreign impurities from dirty snow.

A device for removing snow containing a base chassis, on the frame of which is mounted a heat-insulating body and a heat source, a submersible pump with a suction pipe, a water tank and a float, is taken as a prototype. USSR copyright certificate No. 1534132, IPC: Е01Н 5 / 10,1990 g.

The prototype, like its analogues, has a low service life, depending on the amount of hot water consumed. High dimensions make it unsuitable for local work in the area of residential buildings, shops, restaurants, etc. objects.

The objective of the invention is the creation of an effective device for working both in confined areas and on city roads.

The technical result of the invention is to reduce the operating noise of the snow melter to permissible norms, reduce the cost of transporting snow around the city, increase the efficiency of snow removal by increasing the time resource of work, improving the environment, the versatility of the device when working in confined areas and on city roads.

The technical result of the invention is achieved by the fact that in a snow melter containing a chassis, on the frame of which a heat-insulating housing is mounted, in which a working container with a drainage unit is located, a heat source, a pump with a suction pipe and a float, the heat source is made in the form of electric heaters, the electric inputs of which are made with the ability to connect to a stationary and / or autonomous power source, the chassis is made with the possibility of its movement, the drain node is made in the form of a drain pipe with a shut-off valve, p By the way, the drain pipe is located in the end part of the working tank above the level of heaters, above the heaters there is a suction pipe of the submersible pump, the outlet of which is connected via a branched pipe to a drain pipe after the valve, and also to a water sprayer, in front of which at least one movable hose is installed on the pipe with a float, water flow guides are fixed on the periphery of the working tank, dirt is installed in the lower part of the working tank drain plug.

The current source is made in the form of stationary electric networks of enterprises and residential buildings.

The current source is made in the form of an autonomous electric generator or an electric generator of a towing snow loader, or high-voltage trolleybus networks.

The working tank is equipped with an additional input and means of connection with the exhaust system of the towing vehicle. The movable hose is perforated. The working capacity of the device is closed and equipped with a loading hatch with a lid. A protective cover is installed on the heat-insulating casing from the side of the drain pipe and electric inputs.

The heat-insulating casing is installed with a slope and heat-electric heating elements and a drain plug are installed in the lower part of the heat-insulating casing and working capacity.

The invention is schematically presented below with a submersible pump. The pump can also be installed in a remote version. In the drawing, the following notation: 1 - insulated housing, 2 - working capacity, 3 - chassis, 4 - wheels, 5 - loading hatch with a lid, 6 - heat source made in the form of heaters (TENOV), 7 - drain pipe, 8 - shut-off valve of the drain pipe, 9 - submersible pump, 10 - suction pipe, 11 - switch, 12 - sprayer, 13 - movable perforated hose, 14 - guides (swirls) of the water flow, 15 - float, 16 - dirt drain plug, 17 - protective casing.

Snow melter works as follows.

Before starting work, a snow melter is rolled up to the collected snowdrifts, a small amount of water is poured into the working tank 2 so that its level is higher than the heat electric heaters (TENs) 6 and above the suction pipe 10. Then TENs 6 are connected to the current source (the current source is not shown in the drawing), heat this water to a high temperature of 10-80 ° C. Snow is loaded into a snow melter.

A pump 9 is connected to the current source and heated water taken from the area above the heating elements 6 is supplied through the suction pipe 10, through the switch 11 through the pipeline to the sprayer 12 and through the movable perforated hose (s) 13 to the upper and middle layers of the snow-water mass, which leads to its intensive mixing and melting of snow. The guides (swirlers) of the water stream 14, installed on the periphery of the working tank 2, enhance the effect of mixing and melting snow. The suction pipe 10 takes hot water to the heating elements 6 and constantly directs it through the pipelines to a cold area filled with snow.

Such directed hot flow also increases the intensity of snow processing. A movable perforated hose (s) 13 provided with a float 15 rises along with a rise in the level of melt water, so hot water always flows into the layers of snow mass.

When filling the working tank 2 with melt water, using the switch 11, water is directed through the drain pipe 7 to the local (home) sewage system or to the city sewage system. Melt water can also be drained by gravity through the shut-off valve 8. To clean the container 2 from solid and dirt inclusions, use the drain plug 16. When working on roads while using the road, use a protective cover 17 to keep the electric inlets and the drain pipe from pollution 7. Considering that the working the tank 2 is equipped with an additional input and means of connecting to the exhaust system of a towing or own vehicle, and additional heating with exhaust gases is also used.

The use of this snow melter eliminates the transport of snow over long distances, eliminates the use of freight transport, increases the efficiency of snow removal in places adjacent to housing stock and industrial complexes, to small enterprises and on city roads.
