Description

Technical Field

[0001] This utility model relates to the field of X-ray detection and sorting instruments, and in particular to an X-ray detection device for sorting gangue. Background Technology

[0002] Coal gangue is a solid waste discharged during coal mining and washing. It is a blackish-gray rock with low carbon content and harder than coal, which is associated with coal seams during coal formation. It poses a great challenge to the separation of clean coal. Since both coal and gangue have black surfaces, manual separation is difficult and unsuitable for large-scale separation, resulting in low efficiency. If flotation is used, the different physicochemical properties of the coal and gangue surfaces can be used for separation by foam flotation. However, this method causes significant environmental pollution and harm to human health, and is also unsuitable for large-scale separation. The existing gangue separation device mainly consists of a feeding device, a conveying device, an identification device, a separation device, and a collection device. However, it cannot accurately identify gangue and completely separate gangue from coal. Therefore, it is necessary to solve the above-mentioned technical problems. Utility Model Content

The motor 7 rotates, driving the transmission roller 18 to rotate, and the conveyor belt 21 starts to run. When the coal and gangue on the conveyor belt 21 pass between the X-ray receiving device 11 and the X-ray emitting device 10, the coal and gangue are identified, distinguished and located by X-rays, and the collected information is transmitted back to the control box. When the coal and gangue are transported to the outlet by the conveyor belt 21, the control box issues a command to inject compressed air from the air storage tank 8 into the air storage chamber 13 through the air pipe 12. The gangue falling from the conveyor belt 21 is blown away by the one-way nozzle 14. The gangue is pushed over the inclined isolation plate by a changed parabola, and the coal and gangue are collected separately.
