Coal bunker capable of preventing chute blockage and coal agglomeration

Abstract

The invention relates to a coal bunker capable of preventing chute blockage and coal agglomeration. The technical problem to be solved by the invention is to provide a coal bunker capable of preventing chute blockage and coal agglomeration. The coal bunker capable of preventing chute blockage and coal agglomeration can alleviate the labor intensity of workers and risk during clearance as well as avoid fatal accident of burning a coal feeder. In order to solve the technical problem, the technical scheme provided by the invention is that the coal bunker capable of preventing chute blockage and coal agglomeration comprises a coal bunker, a loosen machine, and a hydraulic stop valve. The coal bunker is cone-shaped. The loosen machine is arranged in a cone part at the lower part of the coal bunker. The hydraulic stop valve is arranged at a coal outlet of the coal bunker. The lower part of the hydraulic stop valve is connected with the coal feeder through an inlet short piece. The hydraulic stop valve is connected with a controller. According to the coal bunker capable of preventing chute blockage and coal agglomeration provided by the invention, the coal feeding quality is greatly improved, and phenomena of smoke fleeing, rise of outlet temperature and manual clearance can be avoided; chute blockage and coal agglomeration are eliminated; the fatal accident of burning the coal feeder is thoroughly eliminated, the cost is saved, and the benefit and safety are improved.

Description

technical field [0001] The invention relates to a coal bunker for preventing coal blocking and shed coal. Background technique [0002] Caking, blockage, and shed coal occur frequently in the existing coal bunkers, and boiler adjustment is difficult to achieve normally, and cannot meet the load requirements of dispatching; the amount of combustion-supporting oil is large, the load rate is low, and the economical operation level is low; the raw coal bunker forms a flue gas channel , the high-temperature flue gas in the furnace reverses, which may easily cause the coal feeder and the belt to burn out; the coal supply is unstable, resulting in coking in the furnace and poor slag discharge; the high bed pressure may easily cause the boiler to be forced to stop; personnel entering the warehouse Frequent excavation and cleaning of coal deposits in the mines pose a great potential safety hazard.
