[0025] When the material is fed into the barrel 2, the material is screened and filtered by the first screen 9 and the second screen 10 in the movable barrel 4, and the filtered material is dispersed by the stirring blade 16 driven by the servo motor 15 to avoid accumulation. At the same time, the connecting piece 17 at the top of the stirring blade 16 and the pulley 18 can intermittently lift the connecting ring 8 while following the circumferential movement of the stirring blade 16, so that the movable barrel 4 is periodically vibrated, thereby clamping the first screen 9 and the second screen 10 to screen the material.
