Vortex cross flow grading type solid particle separating device

Abstract

The invention relates to the technical field of particle separation and discloses a vortex cross flow grading type solid particle separating device comprising a shell. An inner cavity is arranged in the shell. The upper portion of the inner cavity is provided with a feed opening. A conical scattering assembly, an air supply channel and an air guide channel are arranged in the inner cavity, whereinthe small end of the conical scattering assembly is used for receiving materials flowing in from the feed opening, an interval remains between the circumferential side of the conical scattering assembly and the inner wall of the inner cavity to form a flow splitting channel, the air supply channel is used for providing the wind flowing in the direction opposite to the flowing direction of the materials in the flow splitting channel, the air guide channel runs through the circumferential side of the conical scattering assembly. The vortex cross flow grading type solid particle separating device has the technical effects that supplied air of the air supply channel drives powder and part of fine particles to float upward to separate from the material flow; the supplied air of the air supplychannel can also make contact with the material again through the air guide channel, the number of times of penetrating the particle material layer of the air flow is increased, the contact time between the air flow and the particle material layer is prolonged, and therefore the winnowing effect is improved.

Description

technical field [0001] The invention relates to the technical field of particle separation, in particular to a vortex cross-flow classified solid particle separation device. Background technique [0002] At present, solid particle materials often have the problem of uneven particle size and a large amount of impurities between particles. It is usually necessary to use a particle separator to separate solid particle materials of different sizes. Most of the existing particle separators separate substances with different densities by winnowing, and separate the particles through filter plates. However, the separation effect of the existing particle separator is relatively poor, and the particle size obtained after separation is not uniform enough, and powder is mixed between the particles, and the cleanliness is relatively low.
