[0002] With the development of the times, the progress of society, and the rapid development of industrial production, people's environmental awareness has gradually increased. The use of fossil energy has produced a large amount of greenhouse gases and caused damage to the ozone layer, which has brought an impact on people's lives that cannot be ignored. At the same time, the frequency of use of coal, as a non-renewable energy, has been greatly reduced. However, in the process where new energy has not yet been fully popularized, the use of coal fossil energy is still irreplaceable. A large amount of dust is often generated when mining coal. For workers, the harm caused by long-term inhalation of dust is even greater. Traditional dust removal devices are not easy to move, and it is difficult to adapt to the complex terrain formed after mining. The treatment of impurities in the air is also not perfect. When filtering dust in the air, because the filter is in a static state, it is very easy to cause clogging after the filter is used for a period of time, affecting the efficiency of filtering and dust removal. Therefore, it is necessary to design a special dust removal device for open-pit coal mines to solve this problem. Utility Model Content
