Intelligent grading gangue separator

Abstract

An intelligent grading gangue separator consists of an agitating type coal feeder, a grading gangue gathering sieve, an automatic coal and gangue recognition system and gangue separation turning plates, wherein an inlet of the agitating type coal feeder corresponds to an outlet of a coal shearer; an outlet of the agitating type coal feeder corresponds to an inlet of the grading gangue gathering sieve; a reversed-V-shaped coal and gangue separating chute is arranged behind the grading gangue gathering sieve; the automatic coal and gangue recognition system is arranged above the tail end of thegrading gangue gathering sieve; coal and gangue can be separately conveyed into a coal chute and a gangue chute of the reversed-V-shaped coal and gangue separating chute under the control of the automatic coal and gangue recognition system; the gangue separation turning plates are arranged at the tail end of the grading gangue gathering sieve; and the coal chute and the gangue chute separately communicate with a coal conveyor belt and a gangue conveyor belt. Compared with the prior art, the intelligent grading gangue separator adopts the distribution-type coal feeder to solve the problem of nonuniform distribution of materials; the distribution-type coal feeder is combined with the equal-thickness sieve to perform sieving, so that the problem of difficulty in sieving wet and sticky materials can be solved; and corrugated-plate-type sieving plates are adopted, so that the calculation of material running paths can be simplified.

Description

technical field [0001] The invention relates to a screening device, in particular to an intelligent grading and sorting machine. Background technique [0002] As the country's requirements for coal mine safety production, environmental protection, production scale and other indicators have been increased year by year, a number of large and super large coal mines have been newly built, rebuilt and expanded in various places, and the output of raw coal has doubled, and the output of lump gangue has also increased accordingly; At the same time, due to the large-scale mechanized coal mining and the pursuit of mining speed, the thinner gangue layers, faults and subsidence columns are mined together with the coal seam, and all of them are mixed into the raw coal of the mine, increasing the proportion of gangue brought in, so that the lump gangue produced by the raw coal preparation system The rate of gangue has increased significantly, and manual picking of gangue has been unable ...
