[0023] In this embodiment, the crushed waste aluminum materials are put into the feed hopper box 103 and evenly distributed to the sorting system through the material distribution hopper box 104. Meanwhile, the exciting coil 201 is turned on. After the exciting coil 201 in the insulating housing cover 2 is powered on, a high-intensity gradient magnetic field is formed on the surface of the sorting drum 5. The magnetic field penetrates the porous plate 503 outside the medium box 504 and covers the working surface of the drum. A strong magnetic field is generated on the surface of the sorting drum 5, and the reduction motor 401 is started. The sorting drum 5 is driven to rotate through the transmission main shaft 403. When the waste aluminum materials rotate with the drum, the ferromagnetic impurities are adsorbed on the surface of the porous plate 503 of the medium box, and the flushing water tank 501 sprays water on the sorting drum 5 to wash away the non-magnetic aluminum materials.

[0027] In this embodiment, when the waste aluminum materials rotate with the drum, the ferromagnetic impurities are adsorbed on the surface of the porous plate 503 of the medium box, and the flushing water tank 501 sprays water on the sorting drum 5 to wash away the non-magnetic aluminum materials. The aluminum materials fall into the front / rear collection water hopper.

[0028] Specifically, a plurality of medium boxes 504 are arranged inside the sorting drum 5. The medium boxes 504 are connected to the sorting drum 5 by bolts. Among them, the medium boxes 504 are distributed in a ring shape. A perforated plate 503 is arranged on the outer side of the medium box. The perforated plate 503 is connected to the medium box 504 by bolts. An integrally formed partition sleeve shaft 505 is arranged inside the sorting drum 5. The sorting drum 5 is connected to the transmission main shaft 403 through the partition sleeve shaft 505. A front collecting water hopper 105 is arranged on one side of the support shaft 107, and a rear collecting water hopper 106 is arranged on the other side of the support shaft 107. The front collecting water hopper 105 and the rear collecting water hopper 106 are respectively located on both sides below the sorting drum 5.

[0029] In this embodiment, the waste aluminum material is input from the feeding hopper box 103. After being shunted by the distributing hopper box 104, it is evenly spread on the surface of the rotating sorting drum 5.

[0030] A plurality of medium boxes 504 are arranged at intervals along the circumferential direction of the sorting drum 5 to form physically separated adsorption units. The broken aluminum materials cannot completely cover the surface of the drum, and the magnetic field always acts effectively through the gaps of the perforated plate, avoiding the magnetic shielding phenomenon.

[0031] When the drum rotating with adsorbed impurities rotates to the non-magnetic area above the central yoke iron 1072, the magnetic field disappears, and the ferromagnetic impurities break away from the perforated plate 503 and fall into the tailing hopper 101 through the blanking chute 1073. The sorted aluminum materials are graded and guided through the fine material hoppers 102 on both sides of the partition sleeve shaft 505 to improve the purity.

[0032] Working principle: The crushed waste aluminum materials are put into the feeding hopper box 103 and evenly distributed to the sorting system through the material distribution hopper box 104. At the same time, the exciting coil 201 is turned on to generate a strong magnetic field on the surface of the sorting drum 5, and the reduction motor 401 is started to drive the sorting drum 5 to rotate through the transmission main shaft 403. When the waste aluminum materials rotate with the drum, the ferromagnetic impurities are adsorbed on the orifice plate 503 of the medium box 504. The flushing water tank 501 sprays water on the sorting drum 5 to wash away the non-magnetic aluminum materials. The aluminum materials fall into the front / rear collection water hoppers, and the impurities are brought by the drum to the non-magnetic area and fall off, entering the tail material hopper 101 through the blanking chute 1073. The belt drive assembly 301 is started to drive the eccentric main shaft 303 to make the vibration connecting rod 302 reciprocate at a high frequency, and the punching handle 305 pushes the tympanic membrane 306 to vibrate the tail material hopper 101 periodically to prevent the iron slag from piling up and blocking. Finally, the non-magnetic aluminum materials are discharged from the water hopper, dehydrated and sent to be melted.
