Abstract: The present disclosure provides a conveying roller cleaning method, a conveying roller cleaning device, and a material tape conveying equipment. In the conveying roller cleaning method, the conveying roller is configured to convey a material tape, and the cleaning method includes: connecting a head end of an adhesive tape with a tail end of the material tape; and the material tape pulling the adhesive tape to move so as to make the adhesive tape pass through the conveying roller and remove impurities from a surface of the conveying roller. The conveying roller cleaning method can clean the conveying roller.

Abstract: A separation device is described. The separation device includes a rack, a turntable rotatably disposed on the rack; and at least one magnetic element disposed on the turntable. The turntable includes a top surface, and the magnetic element is recessed in or flush with the top surface. The separation device includes a separation membrane detachably disposed on the top surface. In some cases, the at least one magnetic element comprises a plurality of magnetic elements, and the plurality of magnetic elements are spaced apart along a circumferential direction of the turntable. The separation device and a material separation method disclosed are capable of reducing impurities in a slurry.
