[0002] Large centrifugal fans are widely used for ventilation and cooling in factories, mines, tunnels, cooling towers and buildings.

[0003] The utility model patent application document with publication number "CN219549154U" discloses a centrifugal fan, which is mainly composed of a centrifugal fan body, an air outlet pipe, a motor and a transmission mechanism. When the air supply direction of the air outlet pipe needs to be changed, due to the sealed active connection between the air outlet pipe and the centrifugal fan body, the motor is controlled to drive the air outlet pipe to rotate synchronously through the transmission mechanism, thereby changing the direction of the air outlet pipe, thereby adjusting the air supply direction of the air outlet pipe as needed.

[0004] The centrifugal fan disclosed in the above document has the following defects: during use, the air inlet end of the centrifugal fan inhales a large amount of dust particles, causing the dust particles to settle and clog inside the centrifugal fan, affecting the working efficiency. A filter is currently installed at the air inlet end, but the dust particles will cause the aperture of the filter surface to be clogged, making it difficult to clean it in time, which will affect the filtration of impurities in the air and reduce the efficiency of air filtration.

[0005] It can be seen from this that the existing centrifugal fans do not have a good dust removal structure, and it is necessary to improve the existing deficiencies and provide a dust reduction centrifuge for mining. Utility Model Content
