Description

The invention relates to the field of cleaning streets and roads from snow mass and can be used in municipal services, transport and industrial enterprises and other territories.

Known snow melting installation containing a base on which a melting chamber is mounted, closed on top with a grill and having an inclined bottom, pipes for supplying and discharging water from the chamber, located in the latter, and a melting intensification device made in the form of a main shaft mounted in the chamber with rigidly fixed on it with blades of various lengths, an additional shaft with blades placed between the blades of the main shaft, which are equipped with sprockets rigidly fixed to them, interconnected and with a chain drive and a profile cam mounted from the main shaft mounted on the tank wall, a roller mounted on the end of the grate, and interacting with a cam, a tray pivotally mounted at the interface between the inclined bottom and the vertical wall of the chamber, while the end of the grating opposite the roller is pivotally fixed a hole for the indicated tray is made on the camera and in the vertical wall of the camera, and the hole around the perimeter is blocked by the wall of the tray (a.c. RF №949046, 08/07/82, bull. No. 29).

The disadvantages of this snow melting installation are the need to provide it with heated water for melting the snow and electricity to drive its melting intensification device, which is not always possible and economical.

Closest to the proposed snow melting machine is an installation for forced melting of snow, containing a bath with compartments for receiving and melting the snow mass, separated by a perforated partition in the form of a grid, one of which is made with the possibility of loading snow mass through the grate in the upper part and with pallets for collecting garbage in the lower part, and in another there is a device for heating water with combustion products of liquid or gaseous fuels by submersible burners and an insulated compartment for melt water communicating in the lower part with the compartment for snow mass and through the hole with the lower part of the compartment for heating water, and in the upper part has a drain hole associated with treatment facilities, a pump for taking water from the bath from the surface layers and supplying it through nozzles a pipeline located around the perimeter of the specified compartment for snow mass for irrigation, a device for removing water from the bath in the form of an additional pump, the suction pipe of which is made with the possibility of water intake from its surface layers, and etatelny pipe connected to the heating system tank of diesel fuel, fuel pump, fuel line, an air blower to the suction and discharge lines, gas cylinders for ignition submerged burners with a pressure regulator, a gas pipeline and the gas igniter (RF patent №2173744, 20.09.2001).

The disadvantages of this installation for forced snow melting are its complexity and high cost, as well as high operating costs.

The technical result of the proposed snow melting machine is to simplify its design, reduce its cost and operating costs.

The specified technical result is achieved by the fact that in the proposed snow melting machine containing a bath with a grate in the upper part for receiving and melting snow mass and an opening for draining melt water, a burner, gas cylinders with a pressure regulator, gas pipe and igniter, at the bottom of the bath vertically installed partitions, parallel to its horizontal longitudinal axis of symmetry, through one opening between which gas burners with an electric igniter are installed, and in the openings between the indicated partition without gas burners in the bottom of the bath there are slots along the length of the bath and under this bottom of the bath, below the gas burners, there is a chamber for melt water with a drain hole, which simplifies its design, reduces its cost and operating costs.

The drawing shows a diagram of the proposed snow melting machine.

The snow melting machine includes a bath 1 with a grate in the upper part (not shown in the diagram), under the bottom 2 of which there are gas burners 3 connected by gas pipelines through a valve 4 and a pressure regulator 5 with gas cylinders 6, an electric igniter (not shown in the diagram) and a chamber for melt water 7 located under the gas burners with a drain hole 8. At the bottom of the bath bottom, along its length parallel to its horizontal longitudinal axis of symmetry, vertical partitions (made of sheet material) 9 are installed, through one opening between which gas burners 3 are installed with the electric igniter, and in the openings between said baffles without gas burners in the bottom of the tub along its length, there are slits (slit) 10 for draining of melt water from the contact zone (melting) from the bottom of the bath to thaw snow water chamber. For access to oxygen gas burners and gas removal, the snow melting machine has ventilation windows. Ignition of gas burners is carried out by an electric igniter from the electric network or through a transformer from the vehicle’s power supply system (not shown in the diagram). In the back wall of the bath there is a hatch (not shown in the diagram), through which the bottom of the bath is cleaned with a profile scraper installed in a non-working position near the front wall (left) of the bath and with handles for moving it along the bottom of the bath located at this hatch from the trash. Cleaning the chamber for melt water from sediment and small impurities can also be carried out through hatches (not shown in the diagram) with scrapers or installing trays in it for collecting garbage with periodic removal when filling through these hatches, emptying and installing them again. To intensify the process of melting snow, the bath can be closed with lids (not shown in the diagram). The snow melting machine has a base 11.

Snow melting machine operates as follows. The bath 1 is filled (for example, with a loader in the case of its ground installation) with snow through a receiving grate, on which objects larger than its cell remain. They are deleted by the operator. Then the gas valve 4 is opened and the gas burners 3 are lit with an electric igniter, which begin to heat the bottom of the bathtub 2. Upon contact with the hot bottom of the bath, the snow melts and the melt water formed during this melting immediately flows through the slots 10 in the bottom of the bath 2 between the partitions 9 into the melt water chamber 7, thus eliminating the formation of a water layer between the hot bottom of the bath and snow mass, which reduces intensity of melting snow. As a result of this, the melting of snow occurs almost due to its direct contact with the hot bottom of the bath and further heating of the resulting melt water and the heat consumption by it is excluded. When melt water passes through the slots in the bottom of the bathtub, it is carried away by sand inclusions that can occur in contaminated snow. In this case, they can settle and accumulate in the chamber for melt water in the form of sediment. Settled melt water from the chamber 7 through the drain hole 8 pipe and sleeve (not shown in the diagram) can merge, for example, into the sewer or other places (containers).

When disposing of snow by melting, the proposed snow melting machine can be installed and operated on a trailer and, if necessary, be transported with this trailer by a vehicle to a specified location for snow disposal.

When using the proposed snow melting machine stationary, instead of using gas cylinders, it can be connected to a gas pipeline, etc.

In a snow melting machine, you can also use a different type of fuel (liquid or gaseous) and the corresponding type of burner.

The use of the proposed snow melting machine simplifies its design, reduces its cost and operating costs.
