Abstract

The invention relates to an up feeding and down feeding double-grading type high-efficient powder concentrator, which mainly consists of an upper case, a middle case, a lower case, a transmission support frame, a baiting collection pipe, a grading rotor, a main shaft sleeve, a main shaft, a material spreading disc, a grading blade, a speed reducer, an electric motor and the like, wherein the speed reducer and the electric motor are arranged on the transmission support frame. The invention is characterized in that the upper part of the middle case is connected with the upper case, the center position of the upper case is connected with an air outlet large bent pipe, the top of the upper case is connected with a material inlet pipe, the lower part of the middle case is connected with the lower case, the lower case is provided with a material and gas inlet vertical pipe, and the material and gas inlet vertical pipe is provided with a regulation air valve. The upper case is formed by a plane cross-section hollow cone and a hollow cylinder through up and down butt joint split welding, the middle case is a reverse plane cross-section hollow cone, and the lower case is formed by an inclined cross-section hollow cylinder and an eccentric inclined cylindrical baiting tube body through connection. The invention has the advantages o large material processing capability, good dispersivity, high powder concentration efficiency, low air resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of powder material separation or particle classification, and in particular relates to a double-stage high-efficiency powder separator with upper and lower feeding. Background technique [0002] The type of powder separator can be divided into: dry method (air type) sorting equipment and wet method (main medium is water) liquid sorting equipment according to the state of the material powder selection medium. It can also be divided into: gravity sedimentation type powder selection equipment, inertia type powder selection equipment, centrifugal force type powder selection equipment and jet vortex type powder selection equipment according to the material powder selection process. The invention belongs to the type of dry-process aerodynamic type, centrifugal force type vertical cage type powder separator with forced eddy current. The invention belongs to the type of dry-process aerodynamic type, inertial force ...
