Abstract

Snow melting plant (hereinafter referred to as the Snow Melter) refers to snow melting machines. The invention relates to a means for cleaning road surfaces from snow.

The snow melter is installed on specially prepared vehicles, and can also be used as a stationary melting point of snow.

The essence of the invention is a thermally insulated hopper with a shower manifold located above the entire area of melting snow. Water is supplied by the pump from the bottom of the hopper, and is heated to a temperature of 80-90 ° C by electric water heating elements. The water obtained after the melting of snow is discharged into a drain sewer located along the transport route, thereby reducing the time it takes to clear the streets of snow. The tightness of the structure reduces energy consumption. The use of electric heating elements eliminates the emission of harmful products formed during the melting of snow.

Rapid snow melting, mobility and widespread use of drainage and city drainage networks in the city allows the use of a snow melter on busy highways and in residential areas of the city. Timely and high-quality snow removal from highways eliminates the formation of congestion and reduces accident rate on the road.

Known snow melter (RU 2195526 from 11/15/2001), where snow is melted due to the combined air heating system in the snow melting hopper:

Known snow melter (RU 57296 dated 10.25.2005), the use of electric low-voltage plastic tubular heaters, on which snow is dumped:

Known snow melter (RU 2407854 from 05/14/2009), the use of a water jacket for the engine cooling system with the inclusion of microwave lamps.

The disadvantages of the known devices are low heat transfer, which increases the time for melting snow, technical difficulties in creating the necessary conditions for the rapid melting of snow, as well as low permeability of heat currents into the volume of the melted snow.

The desired technical result is the acceleration of the snow melting process; due to the forced penetration of hot water inside the volume of melted snow. Concentration of thermal water currents and formed steam in the snow melting area.

This technical result is achieved by intensively irrigating a metered amount of snow into a melting chamber with water heated to a temperature of 80-90 ° С by electric heating elements; an autonomous power station with a capacity of up to 10 and more kW is used to power the snow melter.

The volume of snow and the temperature of the melting water are selected so that steam is formed that softens the snow during loading and melting, thereby speeding up the process of snow melting. The process of melting snow is carried out by hot streams of water flowing out of the shower collector. The distance between the trickles of water is 5-10 cm.

For the concentration of thermal convection currents, the bunker of the snow melter has 3 compartments (Fig. 1).

The first compartment is the compartment for supplying snow to the melting zone, made in the form of an inclined conveyor belt. Due to its position, it facilitates loading of snow, and eliminates the use of additional loading equipment, and thereby reduces costs.

The second compartment is the melting compartment of snow, consists of three zones. The first zone is the water heating zone, which includes a water pump and a heating element. The second zone is a shower manifold made in the form of a partition with many holes, acting as an irrigator and distributor of hot water over the melted snow zone. The third zone is the melting zone of snow. It is made in the form of grate-irons for short-term retention of snow until it is completely melted. Short-term retention of snow in the third zone is necessary for inclusion in the process of melting convection currents of hot steam and air rising from the third compartment.

The third compartment serves as a sump and filter. The water must be cleaned of solid waste of fine gravel, sand, etc. before being discharged into a drainage sewer.

The snow melter performs the function of snow melting and completely eliminates the long-term storage of melt water in the hopper. This condition allows you to reduce the cost of reheating water supplied to the shower manifold. A separate container is installed for the snow melter, for storage and transportation of melt water, this container can be on the vehicle or have the form of a trailer. With stationary use of a snow melter, melt water can be discharged into the city's sewer system through a filtration system.

To clear the hopper of solid precipitation (in the form of gravel, coarse sand, etc.), it is planned to install a screw pick-up, the main purpose of which is to carry out solid precipitation outside the hopper of the snowmaker and accumulate them in a specially designated vehicle niche, for their subsequent scattering onto roadbed.
