When the material slides down along the spiral material channel 4, the material can slide out from different outlets according to the weight difference of each component in the material, wherein the heavy material always slides down along the spiral material channel 4 and is finally discharged through the heavy material outlet 2. Because the spiral material channel 4 is provided with the light material outlets 3 at intervals, the air separation chamber 6 is internally provided with the fan 5, the air separation suction surface of the fan 5 generating the air separation suction force is arranged opposite to the material surface of the spiral material channel 4, and the light material outlets 3 are arranged at intervals on one side of the spiral material channel 4 opposite to the air separation suction surface. Therefore, when the materials slide down along the spiral material channel 4, the light materials pass through the light material outlet 3 arranged at the corresponding position of the suction surface of the fan under the action of the suction force of the fan, and are discharged through the light material outlet 3 by the suction force of the fan 5, so that the separation of the light materials and the heavy materials is realized.

As shown in fig. 1, furthermore, the spiral material channel 4 is arranged on one side of the air separation chamber 6. In particular, the spiral material passage 4 may be arranged on the left side of the air separation chamber 6, or may be arranged on the right side (not shown) of the air separation chamber 6. The spiral material channel 4 is mainly used for increasing the winnowing separation distance when the material slides downwards along the spiral material channel 4, so that the winnowing separation effect is better.

In this embodiment, the spiral material channel 4 may be disposed on the left side of the air separation chamber 6, or may be disposed on the right side of the air separation chamber 6, and is separated by air separation when the spiral material channel 4 carries the material and gradually slides down.

Further, as shown in fig. 1, the material inlet 1 is arranged at the top of the air separation chamber 6, and the heavy material outlet 2 is arranged at the bottom of the air separation chamber 6. The material enters into the spiral material passageway 4 that sets up in air classification room 6 through pan feeding mouth 1 at air classification room 6 top, then along spiral material passageway 4 landing gradually downwards, the light material is discharged through the light material export 3 that passes the suction surface corresponding position setting of fan 5 under the effect of the suction of fan 5, and the heavy material then continues landing downwards under the effect of gravity, finally is discharged from the heavy material export 2 that sets up in air classification room 6 bottom.

Further, as shown in fig. 1, at least 2 light material outlets 3 are provided. According to the foregoing, the light material outlets 3 are disposed at intervals on the spiral material passage 4 to increase the number of air separation and improve the air separation effect.

When the materials pass through the primary air separation light material outlet 31, a part of the light materials are discharged from the primary air separation light material outlet 31 after being air separated, so that the air separation of the light materials and the heavy materials is realized. And a part of light materials still mixed in the heavy materials continuously slide downwards after passing through the primary air separation light material outlet 31, and are discharged from the secondary air separation light material outlet 32 after being air separated when passing through the secondary air separation light material outlet 32, so that the secondary separation of the heavy materials and the light materials is realized, the separation effect is better and more thorough, and the aim of improving the air separation effect is fulfilled.

It should be understood that, in order to further improve the effect of the air separation of the heavy material and the light material, the light material outlet 3 may be set to be 3, 4 or 5 or even more, so as to realize three times of separation, four times of separation or five times of separation or even multiple times of separation of the material and the light material, so that the effect of the air separation is better.

Therefore, the fan chamber 52 should further comprise a wind power adjusting device 54, and the fan adjusting device 54 is connected with the fan motor 53 for controlling and adjusting the air separation suction force of the fan 5. The suction force of the fan 5 should be set to just suck the light material to the light material outlet, but not to suck the heavy material to the light material outlet 3, and the wind power should be set specifically according to the actual situation, which is not specifically limited in this embodiment.
