Description

Technical Field

[0002] Coal is the most important solid fuel and a type of combustible organic rock. It is formed by lush plants that grow in a certain geological age. In a suitable geological environment, it gradually accumulates into thick layers and is buried under water or in mud. It is formed by natural coalification over a long geological period. After coal is mined from the mining area, it contains a large amount of dust and impurities, and it is easy to stir up dust during transportation.

[0003] In the existing method of conveying coal, water is often sprayed on the surface of the coal ore to suppress dust. However, the coal easily adheres to the surface of the conveyor belt after contacting the water, which is inconvenient to clean. If too much coal adheres to the surface of the conveyor belt, it will cause the conveyor belt to consume a lot of kinetic energy when rotating.

[0004] For this reason, a dust prevention device for coal production is proposed. Utility Model Content
