Description

Technical Field

[0001] The invention relates to the technical field of coal slime recovery and separation equipment, and in particular to coal washing equipment capable of recovering coal slime. Background Art

[0002] Coal washing is an indispensable process in coal deep processing. The coal mined directly from the mine is called raw coal. Many impurities are mixed into the raw coal during the mining process, and the quality of coal is also different. Coal with low intrinsic ash content and coal with high intrinsic ash content are mixed together. Coal washing is an industrial process to remove impurities from raw coal or to classify high-quality coal and low-quality coal. A large amount of coal slime will be produced in the coal washing process. This coal slime needs to be recycled. Coal slime recovery is usually carried out by filtering, screening and dehydration.

[0003] When the existing coal slime recovery equipment is in use, water is usually used for flotation separation during screening. However, this separation method will cause a small amount of coal blocks to be contained in the coal slime, resulting in incomplete separation. Since the water cannot be recycled, water resources are wasted. In addition, when the coal slime is dehydrated, it is easy to cause incomplete dehydration of the coal slime. In addition, this equipment occupies too much area, resulting in inflexible use range, thereby reducing work efficiency. Therefore, a coal washing equipment with coal slime recovery is proposed.
