Abstract

The invention discloses a coal conveying device used for conveying coal into a boiler. The coal conveying device comprises a screw conveyor and an anti-blockage assembly. A screw and a plurality of spiral blades are arranged in the screw conveyor. The screw pitches between every two adjacent spiral blades are gradually increased in the material conveying direction. One end of the screw conveyor isconnected with a conveying pipeline obliquely arranged between the screw conveyor and the boiler. The anti-blockage assembly comprises a stirring piece and a drive piece. The conveying pipeline is provided with a sliding groove. The stirring piece comprises a stirring part and a movable part, wherein the stirring part is arranged in the conveying pipeline in a sliding manner, and after the movable part penetrates out of the sliding groove in a sliding manner, the movable part is arranged at the outer portion of the conveying pipeline in a protruding manner and is connected with the drive piece. The screw pitches between every two adjacent spiral blades in the screw conveyor are gradually increased, stacking of coal in the screw conveyor is reduced, meanwhile, the stirring piece is arranged in the conveying pipeline in a sliding manner, and through reciprocating of the stirring piece in the conveying pipeline, coal blockage is prevented.

Description

technical field [0001] The invention relates to the technical field of conveying machinery, in particular, to a coal conveying device. Background technique [0002] In factories that use boilers to burn coal, screw conveyors are generally used to transport the coal in the coal bunker to the boiler. However, due to the moisture in the coal, when the coal is transported to the inlet end of the boiler, the hot gas in the boiler will make the coal in the coal Evaporation of water can easily cause coal to become rigid in the pipeline for conveying coal, thereby blocking the inlet of the boiler, and the blockage of coal at the inlet of the boiler will also easily cause coal accumulation in the screw conveyor, which will cause difficulties for the normal operation of the factory. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the above-mentioned problems existing in the prior art, a coal conveying device for...
