Description

Technical Field

[0001] The invention belongs to the technical field of coal sorting, and in particular relates to a lump coal sorting vibrating bed with a stirring device. Background Art

[0002] At present, the sorting processes used in coal preparation plants are mainly divided into wet sorting and dry sorting, among which wet sorting is the most widely used. Wet sorting is divided into jigging coal sorting, shallow trough sorting machine sorting, heavy medium cyclone sorting, spiral sorting, TBS interference bed sorting machine sorting and flotation machine sorting according to the sorting system; according to the sorting particle size, it is divided into lump coal sorting, fine coal sorting, coarse coal slime sorting and fine coal slime sorting. At present, the typical sorting process is to classify the raw coal according to a certain particle size, and the classified lump coal enters the shallow trough sorting machine, and the fine coal enters the cyclone.

[0003] There is a lot of gangue mixed in the raw coal mined underground in coal mines. At present, most of the raw coal in coal mines is directly lifted to the surface, and the coal and gangue are separated by the ground processing system. The gangue is dumped in the gangue mountain, which poses a great threat and harm to the ecological environment and conditions of the mining area. With the improvement of environmental awareness, the environmental standards and related requirements of the mining area development process are becoming more and more stringent, and negative effects such as environmental pollution are becoming more and more difficult to accept, and even affect the survival of coal mines. Eliminating the harm of gangue and the comprehensive utilization of gangue have become arduous tasks that coal enterprises need to solve urgently.

[0004] Lump coal resources are often accompanied by gangue. How to separate lump coal from gangue has always been a difficult problem in the industry. Existing lump coal sorting is basically done by X-ray sorting or manual sorting. The disadvantages are: X-ray sorting has a large error rate and limited production capacity or processing volume; manual sorting requires more manpower, is greatly affected by the working environment, and has a very small processing volume. Existing X-ray sorting or manual sorting requires a large sorting site, which results in the promotion of X-ray sorting or manual sorting technology being subject to great site restrictions.
