Problems solved by technology

[0003] However, the current coal and gangue sorting devices in the market have the following problems: 1. The size of the coal and gangue sorting equipment is too large, resulting in an excessively large area occupied by the equipment; 2. The traditional sorting equipment is prone to coal stacking during sorting, resulting in coal The phenomenon of stacking with gangue will affect the accuracy of identification and sorting; third, coal and gangue will generate a lot of dust during sorting, which will cause great harm to the health of operators, so it needs to be solved urgently

Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053] see Figure 1-8 , In the embodiment of the present invention, the device is erected under the coal mining and conveying equipment, and the coal and gangue fall into the device for separation and screening. Coal and gangue first fall into the spreading mechanism 10. The spreading mechanism 10 includes a feed hopper 11. The feed hopper 11 is an inverted conical cylindrical structure with openings at both ends and a diameter that gradually decreases from t...

Abstract

The invention relates to the technical field of coal mining equipment, in particular to an annular coal and gangue sorting device and a using method thereof.The annular coal and gangue sorting device comprises a scattering mechanism, the scattering mechanism feeds coal and gangue into a double-layer queuing mechanism, the coal and the gangue fall into a sorting mechanism through the double-layer queuing mechanism, and the sorting mechanism separates the coal and the gangue and feeds the coal and the gangue into a receiving mechanism to be collected; the dust removal box is used for collecting dust generated in the sorting process; coal and gangue can be rapidly and accurately separated, meanwhile, the overall size of the device is reduced, operation is easy, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of coal mining equipment, in particular to an annular coal gangue sorting device and a method for using the same. Background technique [0002] Coal gangue is the solid waste discharged during the coal mining and washing process, and is an associated product in the coal formation process, and its output accounts for about 15% of the raw coal output. Coal gangue will be weathered after being exposed to the sun and rain for a long time; in addition, coal gangue will disintegrate after absorbing water, and it is easy to generate dust, which will deteriorate the quality of the atmosphere in the mining area. In addition, coal gangue contains combustibles such as residual coal and carbonaceous mud. The accumulation of heat inside the gangue hill will cause the danger of spontaneous combustion, and at the same time it will emit a large amount of harmful gases, which will reduce the air quality of the surrounding en...
