[0027] Furthermore, such as Figure 3 As shown, two mounting slots 16 are symmetrically arranged on the inner walls of the box 1 located on the front and rear sides of the filter frame 5.

[0030] Preferred, such as Figure 1-2 As shown, baffles are provided on the right side of both the first sorting plate 121 and the second sorting plate 131.

[0031] Based on the above structure, such as Figure 1-3As shown, during operation, waste aluminum material is dumped into the feed hopper 61 by an engineering vehicle. The fourth motor 64 drives the auger 63 to rotate via the drive rod 62. The auger 63 transports the waste aluminum material to the top of the conveyor drum 6 and discharges it into the crushing unit through the guide pipe 65. The first motor 24 drives two drive gears 22 to rotate relative to each other. The drive gears 22 drive the crushing roller 21 to rotate, and the crushing roller 21 crushes the waste aluminum material.

The third motor 42 drives the linkage roller 4 to drive the transmission belt 41 to transport the waste aluminum material towards the passage 43. When the waste aluminum material passes the bottom of the conveyor belt 32, the electromagnet 33 attracts iron-containing impurities in the waste aluminum material to the bottom of the conveyor belt 32. The second motor 34 drives the conveyor belt 32 to transport the iron-containing impurities towards the first discharge port 12 via the drive roller 3A connected by the transmission. The conveyor belt 32 transports the iron-containing impurities out. When the first discharge port 12 is reached, the electromagnet 33 no longer attracts iron-containing impurities. The iron-containing impurities fall onto the surface of the first sorting plate 121 and fall along the first sorting plate 121 to the rear side of the box 1. When the conveyor belt 41 transports the waste aluminum material to the passage 43, the waste aluminum material falls onto the surface of the guide plate 14 and falls along the surface of the guide plate 14 into the left filter box 5. The vibration motor 52 drives the filter box 5 to vibrate the filter plate 51. The filter plate 51 filters out the aluminum chips, which fall to the bottom of the inner wall of the box 1. The aluminum chips accumulate at the bottom of the inner wall of the box 1 and slide out of the fourth discharge port 17 along the bottom of the inner wall of the box 1, accumulating on the right side of the box 1. The filtered waste aluminum material moves along the filter plate 51 toward the second discharge port 13 and is discharged from the discharge hopper 54 onto the surface of the second sorting plate 131. The waste aluminum material falls along the second sorting plate 131 to the front side of the box 1.
