Abstract

A dispersion machine for removing impurities from a fiver comprises a housing, a feed port and a discharge port arranged on the housing, and several processing components arranged in the housing. The processing component comprises a connection portion and a scraping portion. When the processing component moves, the scraping portion is suitable for contacting the fiber and moves relative to a surface of the fiber so as to remove impurities from the fiber surface. The dimension of the scraping portion is smaller than or equal to 5 mm and the speed of the relative movement is higher than or equal to 3 m/s. A feed screw rod and a discharge screw rod for pushing material are also arranged in the housing so as to feed material, to discharge material and to remove impurities form the fiber surface repeatedly. The dispersion machine can be used to remove impurities from the fiber in the papermaking field, textile field and the like, so as to obtain raw material with a low impurity content.

Claims
