The air supply channel 211 is used for providing air with the material flowing direction opposite to that in the diversion flow channel 208. While the air induction passage 2032 extends through the peripheral side of the tapered dispersion assembly 203.
The existing particle separator has relatively poor separation effect, particles obtained after separation are not uniform enough in size, powder is mixed among the particles, and the cleanliness is relatively low. And in this scheme through toper dispersion package 203, after the inflow is downthehole, because the effect of toper spare, the material flow is umbrella form separation and flows to realize carrying out reposition of redundant personnel to the material of feed inlet inflow and carry out, prevent that the material from blockking up.
Meanwhile, because the air supply channel 211 is arranged in the inner cavity 202, the air supply direction of the air supply channel 211 is opposite to the flow direction of the materials in the flow dividing flow channel 208, and the powder in the particles of the animal materials and part of fine particles float upwards to separate from the material flow through the air belt with the feeding direction opposite to the particle conveying direction, the effects of removing the light powder and not separating the fine particles are achieved, the powder is not mixed between the particles obtained by discharging, and the obtained materials are clean.
And through induced air channel 2032, wind can also be by induced air channel 2032 entering flow distribution channel 208 when again with the material contact, increase the number of times contact time that the air current penetrated the granule bed, further improve the effect of selection by winnowing. And solid particles fall into the air guide channel 2032 in the falling process, and air in the air guide channel 2032 can also perform air separation on materials in the air guide channel 2032, so that the contact time of the times that air flow penetrates through the particle material layer is increased again, and the air separation effect is improved again.

Meanwhile, gaps are left between two adjacent dispersing plates 2031 to form the air induction channel 2032. By the structure of the multi-layer dispersion plate 2031 in which the product increases sequentially from top to bottom, the material is scattered when falling into the first layer dispersion plate 2031, because the area of the next layer dispersion plate 2031 is larger than the area of the dispersion plate 2031 of the previous layer, the material falls into the next layer dispersion plate 2031 again, and so on. And the gaps are reserved between two adjacent dispersing plates 2031 to form the induced air channel 2032, so that the air in the induced air channel 2032 is not only contacted with the materials again for winnowing when being blown into the diversion flow channel 208, but also can be used for winnowing the materials on the upper plate surface of the dispersing layer in the induced air channel 2032, the contact time of the airflow penetrating through the particle material layer is increased, and the winnowing effect is further improved.
