Problems solved by technology

[0003] At present, coal gangue sorting mainly includes wet separation method, dry separation method and manual sorting. Wet separation method mainly includes dense medium method and jigging method. The layered separation of coal and gangue, the method adopts huge equipment, complicated process, low sorting efficiency and pollution to the environment; dry separation method includes the use of roller crushing and the use of coal and gangue due to the different strengths of coal and gangue The light transmittance is different and dual-energy γ-ray transmission is used for identification and sorting. The former destroys the shape of the coal block, the sorting rate is poor, and the equipment is huge, while the latter is expensive, the sorting efficiency is low, and there is radiation; Gangue has disadvantages such as harsh working environment, high labor intensity, easy to mistaken selection or missing selection, etc.

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] An embodiment of the present invention provides a sorting system for coal gangue, such as figure 1 As shown, it includes a frame 1, a conveyor belt 2, a buffer discharge unit 3, a queuing unit 4, a detection unit 5, and a robot grabbing unit 6, the conveyor belt 2 is located on the frame 1, the buffer discharge unit 3, the queuing unit 4. The detection unit 5 and the robot grabbing unit 6 are sequentially arranged on the conveyor belt 2 according to the feeding direction; in this way, coal gangue is slowly fed to the conveyor belt 2 through the buffer discharge unit 3, and then the coal gang...

Abstract

The invention discloses a sorting system for coal gangues. The sorting system for the coal gangues comprises a frame, a conveyor belt, a buffering discharging unit, a queuing unit, a detecting unit and a robot grabbing unit, wherein the conveyor belt is positioned on the frame; and the buffering discharging unit, the queuing unit, the detecting unit and the robot grabbing unit are sequentially arranged on the conveyor belt in the feeding direction. The sorting system for the coal gangues has the advantages of being high in sorting rate, low in sorting cost, low in working intensity, environmentally friendly, and high in automation degree.

Description

technical field [0001] The invention belongs to the technical field of coal gangue sorting, and in particular relates to a sorting system for coal gangue. Background technique [0002] Coal gangue sorting is a coal pre-combustion treatment technology, which is an indispensable link in coal mine production and one of the effective methods to improve coal quality. [0003] At present, coal gangue sorting mainly includes wet separation method, dry separation method and manual sorting. Wet separation method mainly includes dense medium method and jigging method. The layered separation of coal and gangue, the method adopts huge equipment, complicated process, low sorting efficiency and pollution to the environment; dry separation method includes the use of roller crushing and the use of coal and gangue due to the different strengths of coal and gangue The light transmittance is different and dual-energy γ-ray transmission is used for identification and sorting. The former destro...
