The invention relates to the technical field of glass fiber powder raw material processing, and discloses an environmentally-friendly glass fiber powder manufacturing and processing raw material cleaning facility. The environmentally-friendly glass fiber powder manufacturing and processing raw material cleaning facility comprises a box body. A feeding inlet is formed in the top of the box body. The same circular rod is fixed between the front side wall and the rear side wall of the box body, and a sleeve is movably connected with the excircle face of the circular rod in a sleeving mode. An inner box is fixedly arranged on the excircle face of the sleeve, a discharging outlet is formed in the lower end of the left side wall of the inner box, and a fixing plate is fixedly arranged at the upper end of the left side wall of the inner box. A hydraulic cylinder is movably hinged with the top of the fixing plate, and the top end of the hydraulic cylinder is movably hinged with the inner top wall of the box body. A first stretchable flexible pipe communicates between the top of the inner box and the feeding inlet of the box body, and a material guide cover is fixedly arranged at the upperend of the inner wall of the left side of the inner box. The environmentally-friendly glass fiber powder manufacturing and processing raw material cleaning facility solves the problem that due to thefacts that glass fiber raw materials are not thoroughly cleaned by an existing cleaning facility, and a large number of impurities still adhere to the raw materials after the raw materials are cleaned, the product quality is poor after the raw materials are processed.
