The telescopic hydraulic cylinder 3011 performs telescopic behavior, controlling the roller 305 to slide back and forth along the two displacement chutes 301. At the same time, the motor 309 performs corresponding forward and reverse behavior to drive the active pulley 308 and the driven pulley 307 for power transmission, so that several cleaning steel wires 306 outside the roller 305 squeeze the nickel-based alloy powder filled in the mesh inside the screening mesh plate 204, thereby achieving anti-blocking behavior. Then, impurities are discharged through the discharge port 1 401, and the nickel-based alloy powder falls to the unloading plate 206. Due to gravity, the nickel-based alloy powder is discharged through the discharge port 2 402.
