Description

The utility model relates to the field of cleaning roads from snow mass and ice and can be used in municipal services.

A device of snow melting apparatus is known (see US patent No. 5235762, IPC E01H 5/10).

The device comprises a bath for receiving and melting the snow mass, a device for heating the water located in the bath with combustion products of liquid or gaseous fuel, a pump for taking water from the bath and supplying it through nozzles for irrigating the snow mass and a device for removing water from the bath.

The disadvantage of this device is the low efficiency due to the irrational arrangement of the elements of the installation on which the known method is implemented, as well as the inconvenience of maintenance and operation.

A device for forced snow melting is known (see RF patent No. 2173744, IPC Е01Н 5/10, publ. 13.04.2000).

The forced melting device comprises a snow-alloy chamber for receiving and melting snow, comprising a bottom, a pump for supplying water and watering the snow, and a device for removing water, including a discharge pipe. The reception chamber is divided by a perforated partition into two compartments, one of which is configured to load snow mass into it, and in the other there is a device for heating water. The suction pipe of the pump is located with the possibility of intake of water and its surface layers.

The disadvantages of the known device are the low productivity of the installation, increased fuel consumption, a significant emission of harmful combustion products, technological complexity, inconvenience of maintenance and operation.

Closest to the claimed device is a device for forced snow melting (see RF patent No. 2233950, IPC E01 5/10, publ. 04/18/2002), which is taken as a prototype.

The device for forced melting of snow consists of at least one snow-alloy chamber for receiving and melting snow, containing a bottom with a slope and a mechanized receiving hopper with rotary hammer crushers, a pump for supplying water and irrigation of snow and a device for removing water, including a discharge the pipeline, as well as the sand trap, in which the partitions are located with the possibility of ensuring water circulation and which can be performed in conjunction with the snow-alloy chamber or separately, in the latter case they communicate They are installed by means of a pipeline mounted at the calculated level of water overflow. A safety shield is installed below the outlet pipe tray.

The disadvantage of this device is the lack of reliable control over the basic operations for the disposal of snow, as well as the insufficient reliability of the equipment.

The technical result, which is achieved by the claimed utility model, is to increase the level of control over the basic operations for the disposal of snow, as well as the reliability of the equipment.

The problem is solved in that a device for forced snow melting, consisting of a snow-melting chamber for receiving and melting snow, on the bottom, which are mounted on concrete partitions, sand traps with an inclined tray, a mechanized receiving hopper with rotor-hammer crushers, inlet and outlet pipelines, characterized in that it is equipped with a system of automated control and accounting of incoming snow, while the concrete partitions of the chamber are made with columns connected by transverse beams for installing fractions c, wherein a supply conduit is provided with a damper chamber and the drain line grit chambers - a protective grille with a drive.

Figure 1 shows the snow-alloy chamber (side view).

Figure 2 shows the snow-alloy chamber (end view).

Figure 3 shows the sand trap (side view).

The device for forced snow melting is equipped with a system of automated control and accounting of incoming snow (not shown conditionally) and consists of two main units: a snow-alloy chamber 13 and a sand trap 12, and the snow-alloy chamber 13 is divided into working sections by means of concrete partitions 11 on which the carriers are mounted columns 9 with transverse beams for installing rotor hammer crushers 6 and is equipped with a supply pipe 7 with a gate 8, while columns 9 provide the formation of openings 10, providing prot to the wastewater from the sewer network between the sections of the chamber 13. The snow-alloy chamber 13 is connected to the sand trap 12 by means of a connecting pipe 15, while the sand trap 12 contains a slope 5, a drain pipe 1, in front of which a protective grill 2 with a drive is installed, spacers 3, removable metal panels 4 and a grate 14 for removing floating debris.

A device for forced snow melting is as follows.

Snow is fed into the hopper with rotor-hammer crushers 6, crushed by them and then gets into the snow-alloy chamber 13. In chamber 13, the snow is wetted by waste water, which is taken from a nearby sewer collector (not shown conditionally) and fed through a supply pipe 7. Snow loading into the snow-alloy chamber 13 should be made after filling it with waste water to the mark of the tray of the connecting pipe 15. In this case, the end of the supply pipe 7 is closed by the gate 8. In the snow-alloy chamber 13 due to the kinet eskoy and heat wastewater snow mass is melted. Large impurities and heavy contaminants gradually settle in the snow-alloy chamber 13 and accumulate in its sedimentary part. The presence of 13 columns 9 in the chamber, due to which openings 10 are created, ensures the formation of an even mirror of wastewater, which in turn creates the possibility of uniform settling of impurities and contaminants. As the supply pipe 7 becomes clogged with large impurities, it is washed by opening the gate 8 at the end of the supply pipe 7. At the same time, wastewater under pressure pushes large impurities into the snow-alloy chamber 13.

A mixture of wastewater and melt water from the snow-alloy chamber 13 is discharged by means of a connecting pipe into the sand trap 12. In the sand trap 12, additional impurities remaining in the thickness of the melt water and also floating on its surface are precipitated. To prevent sufficiently large floating substances from entering the discharge pipe 1 before the melt water is discharged, a grill 8 is installed in the snow-alloy chamber below the outlet pipe tray 1, and a protective grille 2 with a drive is installed in front of the discharge pipe 1. After accumulating the permissible amount of precipitation in the snow-alloy chamber 13 and the sand trap 12, the supply of waste water and unloading of snow are stopped. Then, a mixture of wastewater and melt water is pumped out from the snow-alloy chamber 13 and sand trap 12, respectively, and the sediment is unloaded. The discharged sludge is pre-dehydrated and then taken to a landfill for disposal.

To ensure objective control of the process of delivery and unloading of snow, the device for forced snow melting is equipped with a system of automated control and accounting of incoming snow (not shown conditionally), which provides video surveillance of the process of unloading snow, as well as reading and entering into the database the necessary information about the organization - supplier and amount of snow received.

The proposed device for forced snow melting can increase the level of control over the basic operations for the disposal of snow, as well as ensure reliable operation of the equipment.
