Abstract

The invention provides a coal gangue comprehensive reuse processing system, which relates to the technical field of coal gangue production and processing, and comprises a raw coal discharge nozzle, the bottom of which is provided with a circularly rotating conveyor belt, and the conveying The inner ring of the belt is provided with several rollers, and the two ends of each roller are fixedly installed on the bottom support plate through bearings. The bottom end of the bottom support plate is provided with support legs standing on the ground. The inner ring of the conveyor belt A servo motor is fixedly installed in the middle; the servo motor drives one of the rollers of the inner ring of the conveyor belt to rotate; the material-pulling and cleaning mechanism of the present invention performs synchronous motion through a reciprocating slide block and a plurality of synchronously swinging pendulums, so that the most The brush holder at the bottom swings back and forth along the curve when it swings above the gangue separation net, pushing the gangue to roll left and right when it rolls down on the top of the gangue separation net, which is beneficial to improve the cleaning of the gangue surface by the cleaning bristles. cleanliness.

Description

technical field [0001] The invention relates to the technical field of coal gangue production and processing, in particular to a coal gangue comprehensive reuse processing system. Background technique [0002] Coal gangue is solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process. Including the excavation gangue during the roadway excavation, the gangue extracted from the roof, floor and interlayer during the mining process, and the gangue picked out during the coal washing process. Its main components are Al2O3 and SiO2, and it also contains varying amounts of Fe2O3, CaO, MgO, Na2O, K2O, P2O5, SO3 and trace rare elements (gallium, vanadium, titanium, cobalt). [0003] Coal gangue sorting is a coal pre-combustion treatment technology. It is an indispensable link in coal mine production and one of the effective meth...
