Description

one

The invention relates to the field of the preparation of building materials before their use, in particular to devices for the preparation of hot waterproofing mastic. five

A known installation for applying 1 hydroisolation material, including a wheeled chassis, a thermally insulated container with flame tubes and fuel injectors, hedgehog-10 sources of air and electricity, a flushing system, pipelines with stop valves, pumps and remote control l.

Also known is a trailer boiler for 15 heating of a live material, including a wheeled chassis, a heat-insulated container mounted on it with nozzles, flame tubes and flue ducts, a compressor, pumps, pipelines with valves and a process control system with thermal sensors 2.

However, in these devices, heat of waste gases is not efficiently used, perhaps incomplete combustion of the fuel, especially when the heating system is started, and uneven heating of the material in the tank and its quality due to immediate

material contact with the walls of the flame tubes, all this reduces the efficiency of the devices.

The purpose of the invention is to increase efficiency by ensuring uniform heating and efficient use of fuel.

The goal is achieved by the installation, which includes a wheeled chassis, a heat-insulated container mounted on it with nozzles and flame tubes, a compressor, pumps, pipelines with stop valves and a process control system with thermal sensors, it is equipped with tubular ribs with an air heater, and the tank has placed on the opposite end of the nozzles tegovuyu cavity with compartments for each flame tube and rotating on the hinges of the partition, forming a labyrinth, in which the air heater is located of the spirit.

At the same time, the tank is equipped with suction and bubbling coaxial devices located along its bottom, interconnected through a pump, and the heat pipes are equipped with transparent fuel collectors and installed with a slope in the direction of the nozzles and with a gap relative to the vessel walls. On . 1 - shows the proposed installation, a general view; .2 is the same, top viewJ in FIG. 3 shows section A-A in FIG. If in FIG. 4 is a section BB in FIG. 3. The unit has a heat-insulated flexure 1 with flame tubes 2 and nozzles 3 and bubble and suction manifolds 4 and 5 located along its bottom and interconnected by means of a pump 6, located from the heat reservoir 7 opposite to the nozzles 3, which has a partition 8, which divides the cavity 7 into compartments according to the number of heat pipes 2 that receive it, the cavity 7 also has partitions 9 swiveling at the hinges that form a labyrinth to move 2 hot gases emanating from the fire pipes ribbed heater heater 10 supplied to the injectors 3 from compressor 11. On the wheeled chassis 12, the fuel tank 13 and tank 14 are also mounted for having liquid, dispensing 15 and intake 16 pipelines and taps 17, 18 and 19. The installation works as follows in a way. The container 1, using the intake pipe 16 and the pump 6, with the valve 19 of the bubbling manifold 4 opened and the valve 18 open, is filled with waterproofing mastic brought by the vehicle. From the fuel tank 13 to the nozzles 3, liquid fuel is supplied, and from the compressor 11 through the heater 10 - air, the fuel is ignited by means of a filament spiral 20. The passage of hot gases generated during combustion through the heat pipes 2 gives off the heat that is tank 1 mastic and when passing through a maze formed by partitions 9, the flow of gases gives off its heat to the air, which is located in a tubular preheater 10 which then flows to the nozzles 3 and thereby contributes to a more complete combustion of fuel, in the in the case of incomplete combustion, especially during the installation start-up, the flame tubes 2 are equipped with transparent fuel collectors 21 and are inclined towards the nozzles 3. After the mastic has been heated to a predetermined temperature using the thermal sensor installed in the tank 1, the air supply is automatically turned off from the compressor 11 and the fuel from the fuel tank 13, the valve .19 of the bubbling manifold 4 opens and switches on the pump 6, which picks up the mastic with the help of the suction manifold 5, again feeds it into the tank 1 through the manifold 4, What is the intensive mixing of mastic with its uniform heating. Next, the valve 17 opens and the mastic is ready through the dispensing conduit 15 to the consumer. Regulation of the duration of exposure of the flow of hot gases to the end of the tank depending on its temperature, eliminating overheating of the mastic and reducing its quality, is ensured by changing the position of the pivotal partitions 9. By performing an installation with an air heater, pivoting partitions in the thermal cavity and a system of closed circulation of the mastic it provides accelerated and uniform heating with economical fuel consumption and more complete heat recovery, which contributes to an increase in the efficiency of the installation. 1. Installation for the preparation of hot waterproofing mastic, including a wheeled chassis, a heat-insulated container mounted on it with nozzles and flame tubes, a compressor, pumps, pipelines with stop valves and a process control system with thermal sensors, which is that, in order to increase efficiency by ensuring uniform heating and efficient use of fuel, it is equipped with an air heater which is tubular with zebras, and the tank has The end face has a thermal cavity with compartments for each flame tube and partitions swiveling at the hinges that form a labyrinth in which the air heater is located. 2. Installation under item 1, characterized in that the tank is equipped with suction and bubbling collectors located along its bottom, interconnected via a pump. 3. Installation on PP. 1 and 2, in contrast to the fact that the flue tubes are equipped with transparent fuel collectors and are installed with an inclination towards the nozzles and with a gap relative to the vessel walls.
