A main exhaust fan is arranged in the dust exhaust channel, and a plurality of dust extraction ports arranged at intervals are arranged on the dust exhaust channel, and an auxiliary exhaust fan is arranged in the dust extraction port. The utility model extracts tungsten-containing dust from the plant through a suction device, and uses a filtering device to filter the dust sucked out by the suction device. The suction device sucks dust into the filtering device through multiple dust exhaust channels and the main exhaust fan for filtering, and multiple dust extraction ports and auxiliary exhaust fans operate simultaneously to discharge dust faster and avoid a large amount of dust remaining.

[0003] The above-mentioned prior art solution has the following defects: the filter structure is located on the surface of the discharge pipe. When the filter structure is blocked and needs to be cleaned, the filter structure is restricted by the discharge pipe, which makes it impossible to move the filter structure, making it difficult to clean the filter structure, thereby reducing the long-term use effect of the filter structure.
