An exhaust port 20 is provided on the upper wall of the collection box 5. An exhaust rotating plate 21 is rotatably arranged at the exhaust port 20.

The filter screen 23 is arranged below the baffle 22.

[0042] During specific use, pass the magnesium ingot to be processed through the stabilizing ring 32 and place it into the fixing frame 26. Then rotate the fixing stud 28 to fix the magnesium ingot in the fixing frame 26. After the fixing is completed, rotate the anti-deformation screw rod 34. The rotation of the anti-deformation screw rod 34 drives the moving roller 35 to press tightly against the magnesium ingot, effectively preventing the magnesium ingot from deforming due to large forces during processing. Press the sealing plate 46, and the sealing plate 46 moves downward. At this time, the return spring 45 contracts, and the cooling port 44 opens. Put dry ice into the cooling chamber 41, and then release the sealing plate 46. The sealing plate 46 resets under the action of the return spring 45 to block the cooling port 44. Fill the box 53 with argon through the inflation port 55 for safety protection. Start the feeding motor 50. The rotation of the feeding motor 50 drives the feeding screw rod 48 to rotate. The rotation of the feeding screw rod 48 drives the moving frame 37 to move. The movement of the moving frame 37 drives the grinding head 40 to move. The movement of the grinding head 40 drives the limit projection 43 to move until the limit projection 43 presses tightly against the stabilizing ring 32. While leaving a grinding space for the magnesium ingot, it provides a contact-type anti-deformation for the magnesium ingot. Start the grinding motor 38. The rotation of the grinding motor 38 drives the grinding head 40 to rotate. The rotation of the grinding head 40 grinds the magnesium ingot into powder. The magnesium powder generated by grinding falls into the adsorption hood 6. As the grinding progresses, the temperature of the grinding head 40 will rise. At this time, the dry ice in the cooling chamber 41 sublimes due to heat, cooling the grinding head 40 and the inside of the box 53, effectively preventing the magnesium powder from burning and improving the safety of processing. The rotation of the feeding screw rod 48 also drives the force-boosting rotating plate 9 to rotate. The rotation of the force-boosting rotating plate 9 drives the connecting rod 10 to rotate and lift. The rotation and lifting of the connecting rod 10 drive the pulling connecting rod 11 to rotate. The rotation of the pulling connecting rod 11 drives the rotating plate 14 to rotate. The rotation of the rotating plate 14 drives the suction rod 15 to extend and retract along the collection box 5. The extension and retraction of the suction rod 15 drive the piston 16 to extend and retract, thereby sucking the collection box 5. When the suction rod 15 moves in the direction close to the rotating plate 14, the collection box 5 is evacuated. At this time, the one-way rotating plate 18 rotates, and the feeding port 17 opens, while the exhaust rotating plate 21 closes. Thus, the magnesium powder generated by grinding is adsorbed into the collection box 5 through the flexible telescopic tube 7 and the adsorption hood 6. When the suction rod 15 moves in the direction away from the rotating plate 14, the collection box 5 is exhausted. At this time, the one-way rotating plate 18 blocks the feeding port 17 to prevent the magnesium powder from being blown into the box 53 again, and the exhaust rotating plate 21 opens to discharge the gas. Under the action of the filter screen 23, the magnesium powder is prevented from being discharged. The above is the specific working process of the present invention. Just repeat these steps during the next use.
