Anti-blocking feeding device of raw coal bin

Abstract

The invention provides an anti-blocking feeding device of a raw coal bin. The anti-blocking feeding device comprises a water pump, a water inlet pipe, a water tank, a water outlet pipe, a valve, a connecting pipe, a storage battery, a device box, a hot air blower, an air pipe and a high-pressure jet nozzle. The water pump is assembled to the upper end face of a supporting frame and connected with the water tank through the water inlet pipe. The water tank is assembled to the right end face of the supporting frame. The water pump is connected with the water outlet pipe through the connecting pipe. The valve is assembled to the annular side face of the connecting pipe. By means of the design, the purpose that the anti-blocking feeding device has the fire extinguishing function is achieved, the storage battery is assembled in the device box, the device box is assembled to the left end face of the interior of the supporting frame, the hot air blower is assembled to the upper end face of the device box and connected with the high-pressure jet nozzle through the air pipe, the problem that a coal outlet pipe opening is blocked due to freezing is solved through the design, and the anti-blocking feeding device is complete in function, safe, reliable, convenient to use and stable in structure.

Description

technical field [0001] The invention is an anti-blockage feeding device for a raw coal bunker, which belongs to the field of mining equipment. Background technique [0002] The so-called coal bunker refers to the container where coal needs to be placed in the production process, which has certain stability and particularity. [0003] Coal itself has a certain water content. In the low temperature environment in winter, the opening of the coal storage pipe in the open air is easy to freeze and block, which affects the use of the coal bunker. To serve mine production, air cannons are usually used to solve the problem of coal outlet blockage. Under extreme temperature conditions, the phenomenon of coal freezing cannot be ruled out, especially in the case of closed coal outlet pipes, coal freezing or even forming a large number of lumps is inevitable. [0004] The existing raw coal bunker anti-blocking feeding device has a single function, which cannot solve the problem that t...

AI Technical Summary

Problems solved by technology

[0004] The existing raw coal bunker anti-blocking feeding device has a single function, which cannot solve the problem that the coal outlet pipe of the coal bunker is blocked due to freezing, and the existing raw coal bunker anti-blocking feeding device does not have its own fire-fighting function. , can not be solved in time, it is said that a new type of raw coal bunker anti-blocking feeding device is urgently needed to solve the above problems
