[0037] The specific working principle and usage method of the present utility model are as follows:

[0038] The utility model provides a grading powder selection structure. When in use, by starting the rotating motors 9, the rotating directions of the two rotating motors 9 are opposite, so that the two ash inlet drums 10 rotate. Then, start the vibrating motor 25, and feed the fly ash into the crushing box 6 through the ash inlet hopper 1. The fly ash is crushed by the ash inlet drums 10 and then falls into the square frame 20 at the uppermost part inside the vibrating frame 19. The fly ash is screened through the filter screen 27 inside the square frame 20. The screened fly ash enters the square frame 20 below the square frame 20 again and is screened again through the filter screen 27 inside, so as to realize multi-stage screening. The screened fly ash is collected by the collection box 23. The start of the vibrating motor 25 can vibrate the vibrating frame 19, so as to improve the screening effect of the filter screen 27. Subsequently, by directly pulling up the square frame 20, the rubber socket plate 22 can be separated from the socket through groove 28, and the fly ash screened inside the square frame 20 can be cleaned up.

[0039] When it is necessary to disassemble and replace the ash inlet drum 10, by respectively rotating the rotating caps 5 on both sides of the crushing box 6, the rotating caps 5 will drive the moving screw 11 to rotate. Then, under the action of the thread groove 16, the limit insertion plate 13 moves, so that the limit insertion plate 13 is separated from the limit through groove 15, thereby releasing the limiting relationship between the positioning insertion plate 3 and the U-shaped plate 4. Then, the disassembly cover plate 2 can be removed. Then, the bolts connecting the mounting frame 17 and the mounting block 18 are disassembled, and the ash inlet drum 10 can be disassembled. Through the reverse steps above, the new ash inlet drum 10 can be installed, so as to avoid the situation that the entire device cannot be used when the ash inlet drum 10 is damaged and cannot be replaced.
