[0028] Working principle: when preparing high-purity molten silicon powder, the raw material quartz glass tube waste is cleaned and dried to remove dust and debris on the surface, and then the raw material and the ball mill are placed together in the interior of the rotating cylinder 3, and then the rotating cylinder 3 is driven to rotate by the first motor 2, so that the raw material can be crushed well, and the crushed raw material is screened to obtain 40-200 mesh molten quartz sand, and then it is acid washed and magnetically separated to obtain high-purity molten quartz sand, and then it is air flow milled to obtain high-purity molten silicon powder with D50 of 1-50μm. When using the screening device 8, the support sleeve 801 is sleeved on the surface of the rotating cylinder 3, and the arc plate 809 is manually controlled to rotate on the surface of the rotating rod 808, and then the two arc plates 809 are sleeved.

When using the extrusion device 9, the rubber ring 909 is squeezed away from the rubber ring 909 by the third spring 910, so that The rubber ring 909 is well pressed on the inner wall of the rotating cylinder 3, and then the second motor 901 drives the second threaded rod 902 to rotate. Because the thread direction of the surface of the second threaded rod 902 is opposite from the middle to both sides, and the two extrusion plates 903 are symmetrically arranged on the surface of the second threaded rod 902, under the restriction of the limit rod 904, the two extrusion plates 903 can be controlled to move towards the middle of the rotating cylinder 3 at the same time, so that the crushed raw materials can pass through the connecting port 5 away from the inside of the rotating cylinder 3. The second motor 901 is started in the reverse direction, and the second threaded rod 902 is driven to rotate in the reverse direction by the second motor 901, so that the extrusion plates 903 return to their original positions. When the extrusion plates 903 return to their original positions, they pass through the conical ring 906.In this way, the rubber ring 909 is squeezed into the interior of the storage groove 907, which to a certain extent prevents the rubber ring 909 from bringing the remaining raw materials back into the gap between the rotating cylinder 3 and the extrusion plate 903 when returning to the original position.
