[0023] Working principle:
[0024] In the first step, when the alloy powder screening device is used, the lid of the screening tank 1 is opened, and then the alloy powder is placed in the large-pore sieve drum 22, and the servo motor 14 is started. The output shaft of the servo motor 14 rotates to drive the transmission shaft column 15 to rotate, and the transmission shaft column 15 rotates to drive the plug-in block 21 to rotate. The plug-in block 21 is rotated by force to drive the large-pore sieve drum 22 to rotate, and the alloy powder is preliminarily screened by centrifugal force. The screened alloy powder falls into the guide funnel 2, and falls onto the small-pore sieve 16 through the discharge port on the guide funnel 2. The transmission shaft column 15 rotates to drive The small-hole sieve 16 rotates, and the small-hole sieve 16 performs secondary screening on the alloy powder, and then the alloy powder screened by the small-hole sieve 16 falls onto the conical tank bottom 13. By designing the alloy powder screening device to perform secondary screening on the alloy powder by the small-hole sieve 16 after screening by the large-hole sieve cylinder 22, the problem of high labor intensity of multi-batch screening by traditional large-hole sieves and small-hole sieves is solved, and the guiding funnel 2 guides the alloy powder to the top of the cone of the small-hole sieve 16, thereby increasing the contact surface between the alloy powder and the small-hole sieve 16, thereby improving the screening efficiency of the small-hole sieve 16 for the alloy powder.
[0025] In the second step, when the alloy powder screening device is used, the alloy powder is in the large-pore sieve drum 22, and the servo motor 14 is started. The output shaft of the servo motor 14 drives the large-pore sieve drum 22 and the small-pore sieve 16 to rotate. The large-pore sieve drum 22 cooperates with the small-pore sieve 16 to screen the alloy powder, and then the alloy powder falls into the conical tank bottom 13. During this period, the transmission shaft column 15 rotates to drive the scraper 23 to rotate, and the discharge pipe 12 is opened. The rotating scraper 23 pushes the screened alloy powder on the conical tank bottom 13 to the discharge pipe 12 for discharge, and then the adjusting bolt 19 is rotated. The force thread of the adjusting bolt 19 adjusts the position of the guide plate 18. When the guide plate 18 slides onto the small-pore sieve 16, the transmission shaft The rotation of the column 15 drives the small-hole sieve 16 to rotate, and the rotating small-hole sieve 16 pushes the alloy micropowder on the small-hole sieve 16 into the arc-shaped notch on one side of the guide plate 18, and then discharges it through the discharge port 11. Since the large-hole sieve cylinder 22 and the plug-in block 21 are plugged in, the large-hole sieve cylinder 22 is directly taken out to collect the alloy micropowder in the large-hole sieve cylinder 22. By adding the guide plate 18 and the scraper 23 to the alloy micropowder screening device design, in the process of screening the alloy micropowder, the guide plate 18 assists in collecting the alloy micropowder on the small-hole sieve 16, and the scraper 23 assists in collecting the alloy micropowder on the conical tank bottom 13, thereby effectively improving the processing efficiency of the alloy micropowder screening device.
