This device is used as the closest analogue.

The disadvantages of the known devices are their low efficiency, which increases energy consumption and time spent on snow melting, technical difficulties in creating the necessary conditions for the rapid melting of snow.

The technical result achieved by the implementation of the developed device is to increase the efficiency of snow melting while reducing energy consumption.

To achieve the specified technical result, it is proposed to use a snow melting plant of a developed design.

The snow melting rotor consists of a device for fastening a movable rotor with gripping plates to collect snow from the road and move it to the sifter sifter. A static smelter is static with respect to a rotating rotor, in the upper part of which has a cutout with a steel screen, the snow falls onto a conical shower manifold under the action of gripping plates and its own weight.

Next, the water is sent through hoses to the strainers with a mesh of 3 and 0.5 mm, and then into a container for collecting melt water. The purified water remains in the tank until it is discharged into the storm sewer, and the screened sand is scattered along the road.

In order to reduce energy costs for water heating, two types of instantaneous water heaters and hydraulically driven water pumps are used. Instantaneous water heaters: 1) a water-water heater implanted with the engine cooling system. 2) an oil-water heater implanted in the engine oil cooling system.

A pump with a hydraulic motor and a water collection tank with a filtration system are installed in the rear of the car. It is planned to install a tank to collect water on the trailer.

The industrial water obtained after the melting of snow is discharged into a storm sewer system located along the route of transport. Thus reducing the time for cleaning the streets from snow. The use of water-water and oil-water flowing water heaters, pumps with a hydraulic motor and sealing the snow melting process eliminates the emission of harmful products formed during snow melting, and also improves electrical safety, reduces labor costs and increases the culture of work.

The process of melting snow is carried out by hot streams of water flowing from a conical shower collector. The conical shower manifold is located in the static compartment of the snow melting rotor. The direction of the water jets is inclined.

To prevent solid precipitation from falling into the melt water collection tank, it is planned to install filtering, self-cleaning mm outside the snow melter hopper and accumulate them in a specially designated vehicle niche, for their subsequent scattering onto the roadway.
