Description

The proposed technical solution relates to the field of snow machines working through the influence of thermal energy, aimed at melting the snow mass, placed in a heated container, namely, snow thawers.

The SNOW DRAGON firm SND 5400 is known for increased productivity, operating both in a mobile version with installation on a trailer platform with a multi-axle wheeled chassis, and in a stationary version for work on the site, containing a power unit compartment with a driver’s room in which the burners are installed being a source of thermal energy, water pumps and other working units as well as a large melting chamber for melting snow, which contains heat exchangers for transferring the heat of the flame entering them and burners and hot gases from the water, filled in the chamber for melting of snow loaded therein, and the bottom of the separation chamber and waste collection system and the precipitation formed in the snow melting process, and their removal through manholes in the side walls. (one).

At the same time, the mobile snow melters СМТ11, СМТ12, СМТ14 (2), as well as the Trekan snow melters (3), which are made approximately one at a time with the SND 5400 snow melter in a design scheme, in which there are waste and sediment separation systems for collecting them in in the form of pallets sliding through the side hatches.

Snow melter SND 5400 (1) in its technical essence, increased power, the possibility of using a trailer with a multi-axle wheeled chassis and the achieved result is the closest to the applicant's proposal and, therefore, is taken as a prototype.

Cleaning the melting chamber from debris and precipitations abounding in the loaded snow and settled in the lower part of the chamber is the most important, necessary process in the operation of snow melters.

However, the prototype, as well as the other analogues mentioned above, has the following disadvantages, due to the existing system of separation and collection of garbage and sediment.

1. To ensure that the melting chamber is cleaned of debris and sediment through hatches, it is necessary to completely drain the water from the chamber. Operation of snow melters has established that initial start-up of equipment is more efficient if snow is loaded into a melting chamber filled with water and then heated. This is necessary to accelerate the melting of the first portion of snow, while subsequent snow loads will already be carried out in warm melt water. Therefore, after each cleaning of the pallets, the chamber must be filled with water. At the same time, water should be delivered to the place of operation of the snow melter, which leads to an increase in water consumption during operation, complication of water delivery, especially at low negative temperatures, as well as additional costs due to the need to connect special vehicles to the snow melter service.

2. Removing garbage and sediment from the chamber, storing it, and loading it into containers designed for transporting it to a household waste warehouse is a rather laborious and lengthy process that requires the use of heavy manual labor and the help of loading equipment. According to the experience of operation of snow melters, the cleaning of the melting chamber, depending on the degree of snow pollution, has to be carried out at least 4-8 times a month and even more often (see source 3).

The listed disadvantages of the prototype cause significant downtimes of snow melting, which, according to estimates, reduces the overall productivity of the equipment by 5-10%, and also increases water consumption and operating costs.

Thus, the main task to be solved in the proposal of the applicant is to increase the efficiency of snow melting, reduce operating costs and increase productivity.

The solution to this problem is achieved by the fact that the snow melter works, both in a mobile version with installation, for example, on a platform of a railway trailer with a multi-axle wheeled chassis, and in a stationary version for work on the site, containing a compartment of power units with a driver’s room in which the burners are installed being a source of thermal energy, water pumps and other working units as well as a large melting chamber for melting snow, which contains heat exchangers for transferring incoming to their heat from the flame of the burners and hot gases to the water poured into the chamber for melting the snow loaded into it and the system for separating and collecting debris and sediments formed during the melting of snow located in the lower part of the chamber containing two inclined planes, united below the chute, and forming the bottom of the melting a chamber for collecting debris and sediment, while a conveyor, for example, a screw conveyor, and an inclined conveyor, for example, a scraper, located at the end wall of the chamber, are installed in the gutter, for the removal of debris and sediment outside the melt noy camera into the bunker, tilting to unload their vehicle or simply to waste, except at bends vertical and inclined walls of the chamber are provided longitudinal pipes with nozzles connected to the water pump to flush sediment and debris from the chute to the inclined walls.

Figure 1 shows a General view of the snow thaw from the side; figure 2 is the same in plan; figure 3 is a cross section of a melting chamber; figure 4 is a rear view; figure 5 is a longitudinal section by the unloading mechanism. The mobile snow melter is mounted on the platform of a railway trailer 1 with a multi-axle wheeled chassis and consists of a power unit compartment 2 with a driver's cab 3 and a melting chamber 4. Burners 5 are installed in the power unit compartment, which are sources of water and snow heating in the melting chamber, pumps 6 water supply to the pipes for flushing sediment and debris, pumping station 7, control panel 8. In the melting chamber 4 there are heat exchangers 9 that transfer the thermal energy of the flame from the burners 5 to the water and loaded into Yeru snow. In the lower part of the side walls of the chamber there are inclined planes 10, 11 united below by a groove 12, forming the bottom of the melting chamber for collecting garbage and precipitation that fell out during the melting of snow. In the groove 12, a screw 13 is installed with a drive from the gear motor 14. At the end wall of the chamber there is an inclined box 15 in which a conveyor 16 is placed with a drive from the gear motor 17. The elevator box 15 in the lower part adjacent to the groove 12 has a window 18 communicating the cavity of the screw and conveyor. In the zone of junction of the vertical walls of the chamber with inclined walls 10 and 11, longitudinal pipes 19 with nozzles connected to the pumps 6 are laid.

Snow melter works as follows.

Before starting work, the melting chamber 4 is filled with cold water, which is preliminarily delivered to the place of operation of snow melters by special vehicles. Using burners 5, the water is heated to a predetermined temperature, after which the chamber is loaded with snow, which, under the influence of warm, constantly heated by the burners, water begins to melt. The volume of water in the chamber increasing due to melting snow reaches the permissible level, and the excess water through the pipe 20 enters the pump station 21, from where it is sent through a hose (not shown in the figures) to the tanks provided in the snow removal train. Inclusions falling out of contaminated snow in the form of debris and sediment roll along inclined planes 10 and 11, which are also facilitated by water jets directed by pumps 6 through nozzles of pipes 19, and accumulate in the area of the groove 12, from where they are fed by screw 13 through window 18 to conveyor 16 , with the help of which they are transported to hopper 22. Since precipitation is removed from the snow melter by an almost continuous stream of different intensities depending on the contamination of the snow, they are collected in hopper 22, which should be cleaned as it is filled, overturning with th cylinder 23, e.g., a dump for transport to a waste storage.

Since the removal of precipitation from the melting chamber is continuous, the process of melting snow in the snow melter may not be interrupted except when it is necessary to empty the hopper, which is very rare due to its large capacity.

Thus, the proposed snow melter in comparison with the prototype has the following advantages:

- cleaning from the accumulation of sediments formed during the melting of snow can be performed without downtime of the snow melter, which affects the increase in its productivity;

- the absence of the need to drain the water from the melting chamber during its cleaning necessitates filling the melting chamber on the working site only once at the beginning of work, which reduces the water consumption and eliminates the subsequent costs of its delivery;

- the lack of pallets and related work on the extraction and purification of precipitation reduces the complexity of the operation of a mobile snow melter.

The indicated advantages of the applicant’s proposal, despite a slight increase in the total cost of the equipment due to the installation of elevators compared to the comparable cost of the prototype, solve the task of increasing the productivity and efficiency of the snow melting machine.
