[0028] By adjusting the angle of the rotating ring 7 through the driving component A9, the size of the overlapping part of the through hole A6 and the through hole B8 can be changed, and the size of the overlapping part determines the maximum size of the powder that can pass through. The adjustable range of the size of the overlapping part is wide, which increases the range of applicable powder selection standards, and can meet different powder selection needs without replacing the powder screening components inside the device, and the adjustment is flexible and convenient; the material is poured into the rotating throwing device 5 from the feed port 4, and then the rotating throwing device 5 driven by the driving component B10 is thrown out from its outlet, and the thrown material hits the rotating ring 7, and the powder of the right size penetrates from the overlapping part between the through hole A6 and the through hole B8 into the space between the inner wall of the outer barrel 2 and the outer wall of the inner barrel 3, and finally can leave from the discharge port B13, and the powder of the wrong size stays in the inner barrel 3, and finally can leave from the discharge port A11, along the discharge pipe 12 to the material recovery place, waiting to be put into again, and the generated smoke and waste gas is pumped from the dust removal pipe 18 to the corresponding dust removal device for treatment.

[0031] Furthermore, the driving component B10 includes a motor B24, a fixed seat 25 and a support column 26. A fixed seat 25 is provided inside the inner barrel 3 below the rotating throwing device 5.

[0035] Furthermore, the bottom shape of the inner barrel 3 is a slope that slopes downward toward the discharge port A11, and the bottom shape of the outer barrel 2 is a slope that slopes downward toward the discharge port B13, thereby reducing the difficulty of discharging the screened powder and the remaining materials.
[0036] Furthermore, the number of the material distribution openings 15 is three.
[0037] Furthermore, a reinforcing rod 27 is connected between the inner wall of the outer barrel 2 and the outer wall of the inner barrel 3. The reinforcing rod 27 disperses the pressure on the inner barrel 3 and improves the load-bearing capacity of the inner barrel 3.
[0038] Further, a rubber buffer 28 is provided inside the rotary throwing device 5 below its inlet. The rubber buffer 28 can reduce the instantaneous impact of the material on the rotary throwing device 5, thereby reducing the probability of the rotary throwing device 5 being damaged by the material.
[0039] The working principle and use process of this utility model:
[0040] A collecting container is installed on each distribution port 15, and the rotating ring 7 is rotated by the driving component A9 to make the size of the overlapping part of the through hole A6 and the through hole B8 meet the powder selection standard, and the valve A16 and the valve B17 are operated to open the passage between the corresponding collecting container and the discharge port B13, and the driving component B10 is started to drive the rotating throwing device 5 to rotate, and then the material is poured into the feed port 4. The material is thrown onto the rotating ring 7 by the rotating throwing device 5, and the qualified powder comes to the outside of the inner barrel 3 and flows into the collecting container along the discharge port B13, the distribution pipe 14 and the distribution port 15. The remaining material remains in the inner barrel 3 and comes to the material recovery point along the discharge port A11 and the discharge pipe 12. After the dust under the current powder selection standard has been selected, the staff adjusts the size of the overlapping part of the through hole A6 and the through hole B8 and the distribution port 15 connected to the discharge port B13 according to the next powder selection standard. After the adjustment is completed, the material is poured into the feed port 4 to select qualified powder. The powder selection standards are generally arranged from fine to coarse. Repeat the above operation several times to complete the powder selection operation of all powder selection standards, remove the collection container, and clean up the remaining materials.
[0041] The above are only specific application examples of the utility model, and do not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
