[0035] Specifically, a wind branch pipe 31 is provided on the top outer wall of the cyclone 3, and a fine powder outlet 33 is provided at the bottom of the cyclone 3. An airlock is provided at the fine powder outlet 33 to prevent leakage of circulating air inside the shell 1.
[0036] In this embodiment, a mounting bracket 21 is provided on the top outer wall of the top shell 11. A drive motor 2 is bolted to the top of the mounting bracket 21. A shaft 23 is connected to the output shaft of the drive motor 2. The shaft 23 is located in the center inside the shell 1 and passes through the top of the top shell 11. A fixing key 22 is inserted into one end of the shaft 23. The fixing key 22 is fixed in the shell 1 by a connecting rod, so that the shaft 23 can remain vertical and will not deflect.
[0037] In this embodiment, the rotating component 4 includes a rotating part 41 inserted into the shaft 23. The rotating part 41 is formed by several metal plates equidistantly surrounding each other. An exhaust plate 42 is sleeved on the outer wall of the rotating part 41. The top of the exhaust plate 42 is fixed to the top of the housing 1 by bolts. The exhaust plate 42 is a circular structure formed by several metal plates equidistantly surrounding each other. The exhaust plate 42 does not rotate with the rotating part 41. A medium-coarse powder cone 43 is bolted to the bottom of the exhaust plate 42. The medium-coarse powder cone 43 is a container for collecting medium-coarse powder. The cone shape facilitates the sliding of the medium-coarse powder at the bottom.
[0038] Specifically, the bottom of the medium-coarse powder cone 43 is provided with a medium powder discharge pipe 6. The medium powder discharge pipe 6 has a certain downward tilt angle so that the medium-coarse powder can be automatically discharged.

[0042] In this embodiment, the air branch pipe 31 connects the two cyclone tubes 3, and the air branch pipe 31 is connected to the air inlet 10 through the blower, so that the air inside the classifier can circulate on its own and prevent air leakage from carrying fine powder to the outside.
[0043] In this embodiment, the rotating component 41, the spreading mechanism 9, and the cleaning component 93 are all mounted on the shaft 23, and are all driven by the drive motor 2 to rotate together.
[0044] Working steps: 1. Power on the drive motor 2 and blower, then feed the material into the housing 1 through the feed pipe 5. The material is dispersed and scattered into the housing 1 by the first spreading disc 91. The second spreading disc 92 further disperses and scatters the material that was not completely dispersed by the first spreading disc 91. The blower blows air in through the air inlet 10 and blows air out from the bottom of the housing 1 upward. Coarse powder moves downward due to gravity and is discharged from the coarse powder outlet 7. The air carries lighter material upward and enters the rotating part 41 evenly through the exhaust plate 42. Then, the medium and coarse powder is screened. Fine powder enters the cyclone 3 through the air outlet 32 and is discharged from the fine powder outlet 33. The medium and coarse powder falls into the medium and coarse powder cone 43 and is discharged from the medium powder outlet pipe 6. This is to achieve the powder selection of the material.
[0045] Second, the cleaning component 93 can remove the material adsorbed on the inner wall of the housing 1 without stopping the work, thereby improving work efficiency.
