Description

Technical Field

[0001] The utility model relates to the technical field of coal mine dust removal, in particular to a negative pressure suction high-efficiency dust removal device. Background Art

[0002] At present, most coal mines at home and abroad use conveyors to transport underground coal, gangue and other materials. It is well known that the conveyor transfer point is one of the main dust-producing places in coal mines that cannot be ignored. Because underground belt conveyors, scraper conveyors and other conveying equipment have a certain speed, and there is often a drop of about 0.5m between the two conveyor belts at the conveyor transfer point, the transported materials are parabolic during the falling process, so a high concentration of dust will be generated. The dust is suspended and diffused in the open space of the underground tunnel under the influence of wind flow to form tunnel dust, which has an extremely bad impact on the underground working environment. Therefore, a dust removal device is used to remove the coal dust.

[0003] The existing dust removal device can only perform adsorption dust removal on a single point, the dust removal range is small, the dust removal effect is poor, and the suction force of the dust removal device is small. Coal dust is easy to adhere to the inside of the dust removal device, causing aging and damage of the dust removal device. The overall practicality is poor.

[0004] To this end, we propose a negative pressure suction high-efficiency dust removal device. Utility Model Content
