Adjusting and screening type underground coal gangue separating device

Abstract

The invention belongs to the technical field of coal gangue separation and relates to an adjusting and screening type underground coal gangue separating device. The device comprises a box body, two feeding baffles, pressure separation devices, a driving motor, a transmission mechanism, a gangue discharging sliding plate, a screening mechanism and a coal outlet; the feeding baffles are symmetrically welded onto the top of the box body; two sets of pressure separation devices are symmetrically mounted below the feeding baffles and are rotationally connected to the interior of the box body; one end of each pressure separation device is connected with the transmission mechanism; the transmission mechanism is located on the outer side of the box body; one side of the transmission mechanism is connected with the driving motor; the driving motor is fixed to the side wall of the box body through screws; and screening and filtering mechanisms are mounted below the pressure separation devices. According to the adjusting and screening type underground coal gangue separating device, the crushing pressure can be adjusted in time according to different hardness of gangue in raw coal, the situation that the gangue is crushed due to the fact that the pressure of the separating device is too large can be prevented, the coal and the gangue cannot be mixed together. The separating device is wide in application range and high in universality.

Description

technical field [0001] The invention relates to the technical field of coal gangue separation, in particular to an adjustment and screening type underground coal gangue separation device. Background technique [0002] Gangue is the solid waste discharged during the coal mining process and coal washing process. It is a kind of black-gray rock with low carbon content and harder than coal that is associated with the coal seam during the coal formation process. It is a kind of mining solid waste. Moreover, after gangue is mined out of the underground, it is easy to cause underground cavities and cause hazards such as subsidence. [0003] Most of the existing separation devices are suitable for working in the mine and require manual assistance, while most of the underground separation equipment adopts a horizontal device to lengthen the conveyor belt for separation. , the horizontal separation device not only takes up space, but also is difficult to use in a curved road environm...

AI Technical Summary

Problems solved by technology

In order to solve the problem that the common separation equipment cannot adjust the crushing pressure, resulting in gangue being crushed and mixed into the coal, it is not easy to screen, and an adjustable screening type underground coal gangue separation device is designed.
