Zusammenfassung:	The utility model provides a fan device for purified cotton conveying. The fan device comprises a fan, a feeding pipeline, a discharging pipeline, a collection stock bin and a circulation pipe. The collection stock bin is arranged on one side of a shell. The collection stock bin is a cover body covering the end, with a blade shaft, of the fan shell. The blade shaft penetrates through the cover body and is in sealing connection with the cover body. A sealing device is arranged between the cover body and the blade shaft. The upper end of the cover body is in a cone shape. The top end of the cone is communicated with the circulation pipe. The circulation pipe winds around the fan shell to be communicated with the feeding pipeline. According to the fan device for purified cotton conveying, the problems of pollution and waste caused by raw material leakage and fault hidden dangers caused by raw material leakage on the fan are solved, the service life of the fan is prolonged, and stable conveying of raw materials is ensured.
