Under the premise of ensuring production safety, steel enterprises should take effective measures such as sealing and sealing for material transportation to prevent visible dust from escaping.

[0003] At present, the belt conveyors used in steel enterprises are equipped with sealing covers and dust removal facilities at the head, tail and drop point where dust is more serious, which can effectively prevent dust from escaping. However, no effective sealing or sealing measures are adopted in the middle. In the process of transporting materials, a certain amount of visible dust will be generated, resulting in the overall inability of the belt conveyor to meet the ultra-low emission requirements of the steel industry.

[0004] Defects and shortcomings of the existing technology:

[0005] 1) The materials transported by the conveyor belt generate dust themselves, and a certain amount of visible dust is produced in the middle of the belt conveyor, resulting in the belt conveyor being unable to meet the ultra-low emission requirements of the steel industry.

[0006] 2) When the upper and lower rollers in the middle of the belt conveyor are in operation, they rub against the belt surface and the material, generating a small amount of visible dust, causing the belt conveyor to be unable to meet the ultra-low emission requirements of the steel industry.
