Coal gangue separation equipment based on dual-energy X rays

Abstract

The invention relates to the technical field of coal gangue separation, in particular to coal gangue separation equipment based on dual-energy X rays. Comprising an X-ray identification device, a first conveying belt, a blowing mechanism and first supports, the first conveying belt is rotationally installed between the two first supports, the blowing mechanism is fixedly installed at one ends of the two first supports, and the X-ray identification device is fixedly installed on one sides of the two first supports; a transmission mechanism is installed on one sides of the two first supports, a discharging mechanism is installed on one side of the transmission mechanism, and a crushing mechanism is installed on the upper portion of the discharging mechanism. The crushing mechanism is adopted, coal briquettes and gangue blocks subjected to primary treatment enter the crushing bin shell through the feeding port, the push plate moves front and back to extrude large coal briquettes and large gangue blocks in the crushing bin shell, the coal briquettes and the gangue blocks are extruded to be in the basically uniform size state, movement interference generated by adjacent coal briquettes and gangue in the later injection process is reduced, and the coal briquettes and the gangue blocks are prevented from being damaged. And the separation effect is improved.

Description

technical field [0001] The invention relates to the technical field of coal gangue separation, in particular to a dual-energy X-ray-based coal gangue separation device. Background technique [0002] Coal gangue separation is a necessary process in the coal mine production process. Removing gangue is also the basis for coal production of clean energy. Reducing gangue particle emissions can reduce PM2.5 unit emissions. Strengthening the comprehensive management of coal gangue is an important research content of the current coal-burning country, and it is also a need for environmental protection and development. [0003] In the prior art, dual-energy X-rays are used to accurately identify coal gangue and then inject and separate coal gangue. After preliminary treatment, coal gangue of different sizes is placed on the transmission belt for identification and separation. During the injection process, larger pieces of gangue may be separated. It collides with the nearby coal, aff...

Problems solved by technology

[0003] In the prior art, dual-energy X-rays are used to accurately identify coal gangue and then inject and separate coal gangue. After preliminary treatment, coal gangue of different sizes is placed on the transmission belt for identification and separation. During the injection process, larger pieces of gangue may be separated. It collides with the nearby coal, affects its own trajectory, and the coal falls into the gangue track or the gangue falls into the coal track, which reduces the separation effect of the gangue, and the gangue of different sizes is sprayed by the same injection mechanism When it is time, it may cause small pieces of gangue to fly out of the orbit, and large pieces of gangue will fall into the coal orbit due to insufficient flying distance, which will also reduce the separation effect of gangue
