Crushing device for coal gangue sorting

Abstract

The invention discloses a crushing device for coal gangue sorting, and belongs to the field of coal gangue sorting. A crushing device for coal gangue sorting comprises a bottom plate, a crushing mechanism, a screening mechanism, a pushing mechanism, a baffle mechanism and a clamping mechanism. The crushing mechanism is arranged above the bottom plate, the two tooth rollers which synchronously and reversely move are arranged in the crushing mechanism to crush the coal gangue mixture, the screening mechanism is arranged below the box body, and the screening plate which can do reciprocating rectilinear motion is arranged in the screening mechanism. The coal gangue mixture which is not fully crushed is left at the upper end of the sieve plate to realize separation, so that the coal gangue mixture which is not fully crushed is conveniently crushed again subsequently, and the crushing sufficiency is improved; the pushing mechanism is arranged at the upper end of the bottom plate to push out coal gangue mixture which is not fully crushed and left at the upper end of the sieve plate, and the phenomenon that the sieving effect is affected due to the fact that sieve holes in the sieve plate are blocked is avoided.

Description

technical field [0001] The invention belongs to the field of coal gangue sorting, and in particular relates to a crushing device for coal gangue sorting. Background technique [0002] In the process of coal mining, raw coal is inevitably mixed with gangue, and the calorific value of gangue is low. If the gangue in the raw coal is not sorted out, it will not only reduce the combustion efficiency of coal, but also emit a lot of smoke and dust during the combustion process. and toxic gases, endangering human health and polluting the natural environment; therefore, coal gangue sorting is particularly important; [0003] In the prior art, coal gangue sorting needs to be crushed first, broken into small particles and then heated, the heated coal gangue mixture is moved to the infrared image acquisition mechanism for infrared image acquisition, and then the coal gangue mixture is moved to the coal gangue The sorting mechanism, according to the color difference of the infrared imag...

Problems solved by technology

[0003] In the prior art, coal gangue sorting needs to be broken first, broken into small particles and then heated, the heated coal gangue mixture is moved to the infrared image acquisition mechanism for infrared image acquisition, and then the coal gangue mixture is moved to the coal gangue The sorting mechanism, according to the color difference of the infrared image of the raw coal and the gangue, the gangue is picked up by the manipulator to complete the sorting; however, when crushing, the coal gangue mixture is partially broken and is not in place with the crushed coal gangue mixture. Mixing occurs and it is difficult to separate, resulting in subsequent sorting effects
