Description

Technical Field

[0001] The utility model relates to the technical field related to coal dust capture, in particular to an underground coal dust capture device. Background Art

[0002] Coal mine dust prevention refers to the general term for preventing various mineral fine particles generated in the coal mine production process, mainly solid particles generated during coal mining, transportation, transshipment, storage and processing that escape into the ambient air. Coal dust is extremely harmful. It not only pollutes the working environment and affects the health of miners, but also the explosion of coal dust can cause serious personal injury accidents. Therefore, a capture device is usually set up underground to collect coal dust, and the coal dust in the air is filtered through the action of the filter inside the device. However, the existing device lacks a cleaning structure on the outside of the filter. After a long time, too much coal dust is easily accumulated on the outside of the filter, which leads to clogging of the filter and inability to maintain an effective filtering effect, thereby reducing the overall coal dust capture efficiency of the device.

[0003] To this end, we propose an underground coal dust capture device to solve the above problems. Utility Model Content
