Abstract

The utility model relates to a rotating type dust remover comprising a machine frame. The machine frame is provided with a motor, a retarding mechanism, a main shaft and a rotating type separating cylinder, wherein the main shaft and the rotating type separating cylinder are integrally and fixedly connected together. A revolving body composed of radial ribbed slabs is install on the main shaft inside the rotating type separating cylinder, wherein the revolving body and the main shaft rotate synchronously. An inner cavity is divided by the revolving body into many separating cavities which are in fan shape along perpendicular direction, and simultaneously partition boards accompanied with through holes are fixed between adjacent radial ribbed slabs along height direction. The partition boards further divide the separating cavities into multicavity chambers, and simultaneously the bottom of the rotating type separating cylinder is provided with a dust collecting device which is composed of a tray and a chassis. Air with dust is sucked into an air inlet on the lower end of the main shaft and then forms tortuous airflow under the action of centrifugal force. The airflow is separated through the through holes of the partition boards, so the dust flies toward the wall of the rotating type separating cylinder and is impinged to fall because of dead weight, and clean air is discharged through an air exhaust outlet on the upper part of the rotating type separating cylinder. The design has the advantages of simple structure, low cost, good dust-proof effect and easy dust cleaning operation. Therefore, the rotating type dust remover is a product of environmental protection for reducing dust pollution.
