Description
Technical Field
The utility model relates to a power station technical field, concretely relates to clear stifled device of coal bunker.
Background
The boilers in the thermal power plant are mostly coal-fired boilers, and each boiler needs to be provided with a coal bunker. In the normal operation process, due to factors such as coal moisture and coal fineness, the coal bunker is always blocked. In the prior art, blockage removal is generally performed by methods of knocking a coal bunker shell, vibrating the shell by an electric vibrating rod needle, poking coal by opening a hole in the shell and the like. However, the method has unsatisfactory effect and seriously influences the normal operation of the boiler.
Therefore, how to improve the blockage clearing way of the coal bunker of the furnace so as to overcome the problems is a problem to be solved by the technical personnel in the field.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a pair of simple structure, clear stifled effectual, convenient operation's clear stifled air bubble of using of boiler coal bunker.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a clear stifled air cannon of using of boiler coal bunker which characterized in that: the air storage tank is connected with an air inlet pipe, and the air inlet pipe is suitable for being connected with an air pump; the coal bunker blockage cleaning device is characterized in that the gas storage tank is further connected with a gas outlet pipe, the end part of the gas outlet pipe is provided with a gas jet, the gas jet is arranged in the coal bunker, the gas outlet pipe is further provided with a pulse valve, and the pulse valve controls compressed air in the gas storage tank to be ejected out of the gas jet at a high speed through the gas outlet pipe, so that the blockage of the coal bunker is cleaned.
As an improvement, the gas storage tank is connected with two gas outlet pipes, the two gas outlet pipes are provided with the pulse valve and the gas jet, one gas jet is positioned at the coal piling position below the coal bunker, and the other gas jet is positioned at the coal dropping port of the coal feeder below the coal bunker. And the coal bunker is sprayed by multiple points, so that the blockage removing effect is improved.
As a conventional setting, an air inlet valve is arranged on the air inlet pipe and used for controlling the air pump to supply air to the air storage tank.
Preferably, one coal bunker is provided with a plurality of air cannons, and a plurality of air cannons are arranged at positions where coal blockage of the coal bunker is easy. Further increasing the blockage clearing effect.
Compared with the prior art, the utility model has the advantages of it is following: the air cannon utilizes the aerodynamic principle, the working medium is compressed air, and the air cannon is composed of a differential pressure device and a quick exhaust valve (pulse valve) for realizing automatic control, so that the air cannon can instantly convert air pressure energy into air jet flow force, generate strong impact force and further achieve the effect of clearing blockage. The air cannon has good blockage clearing effect, can basically solve the problem of coal blockage, and is clean, pollution-free and low-energy-consumption ideal blockage clearing equipment.
