Description

The invention relates to stationary devices for collecting and melting snow and ice, removed from urban areas.

A stationary snow melting installation is known, comprising a loading hopper with a thawing chamber located under the hopper and communicating with it through a hole in the bottom of the hopper, a dirt sump and a multi-tiered tube heater installed in the thawing chamber with adjustment equipment (see AS USSR No. 1081267, IPC E 01 H 5/10, publ. 22.03.84).

The disadvantages of the known installation are the difficulty of removing oversized inclusions from the hopper, the high energy consumption of the installation due to the use of an artificial coolant (tubular heater), the presence of adjustment equipment that reduces the reliability of the installation in cold weather, the possibility of clogging the discharge opening of the hopper and the space between the heater tubes with various contaminants during snow melting .

Closest to the claimed device is a well-known snow melter containing an underground snow receiving chamber with a loading window covered by a grate, a snow melting intensifier made in the form of a collector with irrigation pipes connected to the sewage line, and a submersible sand pump installed in the lower part of the chamber (see USSR AS No. 1576625, IPC E 01 N 5/10, publ. 07.07.90).

The disadvantage of this known snow melter is the low efficiency due to the accumulation of contaminants on the bottom of the chamber, which clogs the suction pipe of the pump, therefore frequent shutdowns of the snow melter are required to remove contaminants manually. Floating pollution in this known device is carried out together with melt and wastewater into the sewer well and clog it.

The objective of the invention is to increase the efficiency of the snow melter while increasing the degree of clarification of melt water and the exclusion of mineral impurities and large floating contaminants in the sewer network.

The problem is solved in that the snow melter containing an underground snow receiving chamber with a loading window covered by a grill, a pipe for the removal of melt water and a melting intensifier, made in the form of a collector with irrigation pipes connected to the sewage line, is equipped with a snow melting channel in communication with the camera, a removable ceiling installed above the channel and a means located in the channel for trapping solid floating contaminants, while the snow melting intensifier is installed in the chamber under etkoy and conduit for removing the melt water is connected to the channel. In addition, it is advisable to equip the snow melter with means for forcing the snow through the grate, which can be performed, for example, in the form of spikes installed with the possibility of reciprocating movement, or install a ceiling and grate horizontally at ground level and use it as a means for forcing snow bulldozer. Means for retaining solid floating contaminants can be made in the form of a shield attached perpendicular to the ceiling in front of the point of connection to the channel of the pipeline for the removal of melt water.

Figure 1 shows a snow melter in longitudinal section; figure 2 is the same, a top view.

The snow melter contains an underground snow reception chamber 1 of a rectangular shape with a loading window 2 covered by a grating 3, and a snow melting channel 4 communicated with the chamber 1 by means of a trapezoidal transition 5. In the chamber 1, under the grating 3, the clearances of which are expediently made with dimensions 150 × 150 mm, are installed the snow melting intensifier, made in the form of a collector 6 with irrigation pipes 7, attached to the sewage line 8. A removable overlap 9 is located above the channel 4 and a pipe 10 is connected to it (channel) for draining melt water into the sewer 11. In the channel 4, in front of the point of connection of the pipe 10 to it, there is a means for trapping solid floating contaminants, which can be made in the form, for example , a shield 12 perpendicularly attached to the floor 9. The grate 3 and the floor 9 are installed horizontally at ground level for convenience by using means for forcing snow through the grate 3. Such a tool can be a known rake or spikes mounted with the possibility of reciprocating movement, or a bulldozer (not shown).

Snow melter works as follows.

Snow transported by road is dumped onto grate 3 with a clearance of 150 × 150 mm. Loose snow freely falls through the openings of the grate 3 into the snow receiving chamber 1. The collected compacted snow and ice are forced through the grate 3, for example, by a bulldozer that moves along the grate, pushes the snow and simultaneously removes large inclusions (stones, pieces of metal, etc. .). The structural dimensions of the grate 3 provide a metered supply of crushed snow into the chamber 1, in which a melting intensifier is installed, which irrigates the falling snow with jets of warm wastewater supplied by a submersible pump 13 from the city sewage line 8. As the chamber 1 is loaded, part of the non-melted snow mass is squeezed out into the snow melting channel 4, where the snow is completely melted due to the kinetic and thermal energy of the wastewater and mineral impurities are separated from it, mainly sand, which accumulate in the sedimentary part of the snow melting channel 4. This is clarified melt water with waste wastewater is discharged by gravity pipe 10 to the city sewer. Large floating contaminants are retained by the shield 12, the lower part of which is better located 0.4-0.5 m below the pipeline 10. As the sediment accumulates in the channel 4, snow loading into the chamber 1 is stopped. The grate 3 and the ceiling 9 are removed, pumped from the upper level melt water and produce the discharge of sediment (sand) construction equipment, such as an excavator. The snow melting channel is emptied once every 12 days.

The proposed snow melter is effective in work due to the forced forcing of snow, the full mechanization of the discharge of sediment and the removal of large heavy and floating inclusions; eliminates the possibility of mineral impurities and large floating pollution entering the city sewer network.
