Dry and wet coal layered treatment automatic dust falling device and using method thereof

Abstract

The invention discloses a dry and wet coal layered treatment automatic dust falling device and a using method thereof. The dry and wet coal layered treatment automatic dust falling device comprises a conveying structure and a dust removing structure. The conveying structure comprises two conveying belts, a feeding baffle, a sealing plate, a sealing shell, a negative pressure fan and a blocking plate. The two conveying belts are arranged up and down through a support. The feeding baffle is installed at one end of the conveying belts. The sealing plate is hinged to the inner wall of the feeding baffle through a hinge. The sealing shell is fixedly arranged at the top of the conveying belts. By means of the conveying structure, efficient classified conveying of dry and wet coal can be achieved, a dust removal function is integrated in the actual conveying process, when dust removal is conducted on dry and wet coal, the problem that the air quality of the working environment is reduced due to dust flying and splashing is avoided, and meanwhile, the detonation problem caused by combustible dust is avoided. Through the combination of a grid plate and a water tank, the air flow containing dust is efficiently adsorbed, a water source is recycled, the dust removal efficiency can be improved, and meanwhile the dust removal cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of dust treatment, and in particular relates to an automatic dust suppression device for layered treatment of dry and wet coal and a use method thereof. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the distance to the surface is very close, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine. Most of the coal mines in my country are underground coal mines. The scope of coal mines includes a large area above and below ground and related facilities. Coal mines are excavated by humans Reasonable space excavated for coal-rich geological layers usually includes roadways, shafts and mining faces, etc. Coal is the most important solid fuel and a kind of combustible organic rock.

Problems solved by technology

[0004] At present, most of the treatment and dust reduction of dry and wet coal focus on the adsorption of dust. In order to avoid the dust in the environment exceeding a certain proportion, which will cause deflagration accidents, the second is to adjust the humidity of coal to avoid spontaneous combustion of coal piles. phenomenon, but the existing equipment often adopts the method of electrostatic dust removal and filtration. In the actual dust reduction process, it is very easy to cause dust accumulation and blockage, and it needs to be shut down for maintenance, resulting in a reduction in actual production efficiency. The second is to use Dust removal for such occurrences often fails to achieve efficient dust removal, and some dust will still enter the working environment, affecting the health of the staff
