Fine powder recovery device

The utility model discloses a fine powder recovery device, comprising a bag-type dust collector, an agitating tank, a stirring pool and a blower, wherein an air outlet at one side of the bag-type dust collector is communicated with the air inlet of the blower, an air inlet at the other side of the bag-type dust collector is communicated with a vibrating screen through a pipeline, a fine powder conveying mechanism is arranged beneath the bag-type dust collector, the feed opening of the fine powder conveying mechanism is communicated with the discharge opening of the bag-type dust collector, the discharge opening of the fine powder conveying mechanism is communicated with the feed opening of the agitating tank, the upper end of the agitating tank is connected with the discharge opening of a cyclone separator through a pipeline, the discharge opening at the bottom of the agitator tank is communicated with the stirring pool through a conveying pipeline, and a hose pump is arranged on the conveying pipeline to pump fine powder in the agitating tank into the stirring pool. The device has the advantages of both reducing the manual workload, but also reducing the influence of dust on the surrounding environment and the harm of the dust to a human body when collecting the fine powder.
