[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal, which is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal, which is an open-pit coal mine. However, a large amount of dust will be generated during coal mining, and if the dust is not handled in time, it will explode, so it is particularly important to design a coal mine dust removal device.

[0003] In the prior art, bag dust removal is often used to filter coal dust in the air of coal mines. The bag is installed in the filter, and the flange on the top cover of the filter is connected to the air inlet pipe. Due to the high content of coal dust in coal mines, the bag in the filter often needs to be replaced. The air inlet pipe flange needs to be removed first, and then the connecting mechanism of the filter top cover needs to be removed before the filter can be fully opened. Such a structural design requires a long time to replace the bag, and the replacement is troublesome, and the dust removal device has a long downtime. Therefore, a new dust removal device for coal mine safety management is proposed to solve the above problems. Utility Model Content
