Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to an underground mine ventilation device. Background Art

[0002] A large amount of dust is generated when mining underground. The dust is deposited on human lung cells and causes "silicosis". It enters the blood and spreads throughout the body to form respiratory diseases, seriously affecting the health of underground workers. Therefore, dust removal and ventilation work in mines becomes very important.

[0003] At present, the fan mainly discharges the dust through the ventilation duct, and the dust in the duct is filtered through the filter plate. However, the filter plate is mainly cleaned manually, which is time-consuming and labor-intensive, and the operation is cumbersome. In addition, when the filter plate is damaged, the entire piece must be replaced instead of only the damaged part, which easily causes a waste of materials. Therefore, it is very necessary to develop an underground mine ventilation device. Utility Model Content
