Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a high-efficiency coal preparation and dust removal device in a coal preparation plant. Background Art

[0002] In the existing coal preparation equipment, the head and tail of the belt are installed under the chute of the clean coal centrifuge. When the clean coal centrifuge is unloading, the centrifugal force causes a lot of wind to fall from the belt to the place where the belt is transferred. The clean coal is constantly falling with the gas, which not only pollutes the surrounding environment, but also makes it difficult to clean the surrounding environment, affecting the quality standardization, and also wastes a lot of clean coal. Most of the existing dust collectors on the market send the coal dust wind into the water tank for absorption, but the coal dust wind generates a large number of bubbles in the local water tank. The local water does not absorb the coal dust enough, and the bubbles easily bring the coal dust out, reducing the dust removal effect. Utility Model Content
