Description

The invention relates to the processing of the snow mass removed from urban areas by its forced melting.

A device is known for processing snow-ice formations removed from the road surface, including a chamber for receiving snow-ice mass and its melting. Inside the chamber is a system of perforated pipes located in the vertical and horizontal plane for supplying the heated fluid. In addition, there is a grinder of snow mass, into which this mass enters through the neck and then into the receiving chamber (see RU Patent No. 2290471 Е01Н 5/00, Е01Н 5/10).

The disadvantage of this device is the low efficiency due to the small size of the chamber with a grinder and the low reliability of the device due to the possibility of clogging the waste collector with solid waste and the difficulty of cleaning it.

Known installation for melting snow, containing a heating chamber, a burner, a fuel source and a blower, a vortex chamber and a fire tube (see patent RU No. 2484199 Е01Н 5/10).

The disadvantage of this installation is low efficiency, due to the dense mass of snow thrown into the heating chamber and requiring significant heat consumption for melting snow, as well as low reliability, due to the absence of a dirt collector to remove debris.

The closest to the proposed installation for melting snow is a method of melting snow (see patent RU № 2337207 Е01Н 5/10). Installation for implementing the method includes a receiving hopper, a device for grinding snow, a snow melting chamber, a set of screws installed in a snow melting chamber, a pallet, a device for collecting solid waste.

Grinding snow to the specified size (1-10 mm) requires a certain amount of time, and the device for grinding snow is an obstacle to the free passage of snow mass into the snow melting chamber. The possibility of blocking the pipeline with solid waste that does not pass through the slot holes is not excluded. In addition, this device has a low efficiency, depending on the amount of consumed hot water and high heat loss due to radiation into the external environment, as well as low reliability due to the possibility of blocking the pipeline feeding solid waste to the waste collection device.

The technical result achieved by the invention, is to increase the efficiency of the installation while increasing its reliability.

This technical result is achieved by the fact that the installation for melting snow contains successively installed receiving, melting and vortex chambers, and the receiving chamber is equipped with a screw, the perforated shaft of which is made in the form of a flame tube. A perforated flame tube with a grid with holes is rigidly fixed in the melting chamber. On the outer side of the front wall of the receiving chamber there is an engine rotating auger, and in the lower part of the front wall there is a damper covering the neck to remove dirt and solid waste. The back of the auger has a knife adjacent to the grill with holes. Behind the rear wall of the melting chamber there is a vortex chamber equipped with a blower, a tangential fuel supply nozzle, and an electric igniter. Under the receiving and melting chambers there is a pan for collecting melt water.

The essence of the claimed invention is illustrated by the technological scheme shown in FIG. one

Installation for melting snow, contains sequentially installed receiving 1, melting 2 and vortex 3 chambers. The receiving chamber 1 is equipped with a screw 4, the perforated shaft 5 of which is made in the form of a flame tube. In the melting chamber 2, a perforated flame tube 6 with a grid 7 with holes is rigidly fixed. Behind the front wall 8 of the receiving chamber 1 is the engine 9, rotating the screw 4 with the shaft 5. In the lower part of the wall 8 is located a valve 10 through which dirt is removed, and the back of the screw 4 has a knife 11 adjacent to the grill 7. Behind the rear wall 12 the melting chamber 2 has a vortex chamber 3 equipped with a blower 13, a tangential fuel supply nozzle 14, an electric fuse 15. In the lower part of the wall 12 there is a nozzle 16 for draining the melt water, and under the chambers 1 and 2 there is a pallet 17 for collecting melt water.

The installation works as follows. The snow mass removed from the road surface is fed into the receiving chamber 1. The air supply is opened through the blower 13 and the fuel supply through the tangential nozzle 14. Air and fuel are mixed in the vortex chamber 3, forming a fuel-air mixture, which twists and then enters the fire tube 6 and perforated shaft 5. The air-fuel mixture swirling in the vortex chamber 3 is ignited by an electric igniter 15. When burning the air-swirling air-fuel mixture, a flame flame is formed in the flame tube 6 and in the tube shaft 5, under the influence of which uniform heating of these pipes occurs. The flame tube 6 emits heat into the melting chamber 2, and the shaft 5 into the receiving chamber 1, and the radiation of heat occurs both through the surface of the tubes and through their perforation.

After turning on the engine 9, the screw 4 is rotated and the snow mass advances and then is pushed through the holes of the grid 7 into the melting chamber 2. As a result of the snow mass stratification, it melts much faster. The melt water through the pipe 16 is poured into the pan 17 which is a sump-drive. Melt water is very soft water, with a minimum content of hardness salts and can be sent for electrolysis with subsequent production of sodium hypochlorite. (disinfectant)

So that during the processing of snow mass contained in its household waste, mechanical inclusions do not clog the holes in the grill 7, on the shaft 5 of the screw 4 there is a knife 11 adjoining the grill 7 and cutting off all the mechanical inclusions stuck to the grill during the rotation. To remove waste accumulated in the receiving chamber 1, open the valve 10 in the lower part of the wall 8, turn on the reverse of the engine 9 and the screw 4 rotating in the opposite direction pushes the accumulated waste from the receiving chamber 1.
