Abstract: A coal and gangue identification device is disclosed. The device includes a rotary supporting frame, a water injection unit, a weighing unit, a liquid level detection device and a processing module. The rotary supporting frame is provided with a loading unit used to load a mineral aggregate. The rotary supporting frame is used to drive the loading unit to rotate on a horizontal plane. In the rotating process of the rotary supporting frame, the loading unit cyclically passes through a water injection region, a material adding region, a volume measurement region and an unloading region which are sequentially disposed on a rotation trajectory of the rotary supporting frame. The water injection unit is used to inject water to the loading unit of the water injection region.

Abstract: The present invention proposes a coal and gangue separation device, including a first supporting seat, a guide part and multiple material bins. The guide part is hinged with the first supporting seat; the guide part rotates in a vertical direction; and inlets of the plurality of material bins are sequentially distributed on a rotation track of a movable end of the guide part. In the coal and gangue separation device of the present invention, the high-pressure airflow of a high-pressure nozzle does not directly act on the materials, but on grate bar driving mechanisms; and cantilever grate bars are driven to rotate by the grate bar driving mechanisms so as to directionally discharge the mineral aggregate. Therefore, the gangue can accurately enter a gangue collection bin; and the clean coal can accurately enter a clean coal collection bin.
