Technical Field

[0001] The utility model relates to the field of coal mining, in particular to a dust removal device for prevention and control of coal mining. Background Art

[0002] A large amount of coal dust is generated during the coal mining process, filling the entire work site. Especially when the fully-mechanized tunneling machine is in operation, the amount of dust it produces is the largest. A large amount of coal dust will reduce visibility in the workplace, affect work safety, and seriously affect the health of workers. The existing coal mining dust removal device is generally a mining dust collector.

[0003] The structure of the traditional dust collector for coal mine prevention and control still has certain shortcomings during use: some dust collectors for coal mines include an air inlet pipe, a clean air chamber, an air outlet pipe and an exhaust fan. The operation of the fan allows air containing coal dust to enter the clean air chamber, and the air is filtered by installing several groups of filter cartridges in the clean air chamber. The filtered air is discharged along the air outlet pipe. However, it is more troublesome to clean the surface of the filter cartridge in this equipment, and the cleaning equipment is easily contaminated with a lot of coal dust during the operation of the fan. Secondly, the coal dust falling from the filter cartridge will enter the bottom of the clean air chamber, but it is more difficult to collect and clean it.

[0004] Therefore, it is necessary to provide a new dust removal device for coal mine prevention and control to solve the above technical problems. Utility Model Content
