[0023] Furthermore, a discharge hopper 202 is fixedly connected to the lower end of the discharge port 201, and the lower end of the discharge hopper 202 is communicated with a feeding point on the melting furnace.

[0024] Furthermore, a motor box 204 is fixedly connected to the middle of one side of the continuous feeding device 2 , and a motor 205 is fixedly arranged inside the motor box 204 .

[0025] Furthermore, one end of the conveying shaft 3 passes through one side of the continuous feeding device 2 and extends to the inside of the motor box 204 and is connected to the output shaft of the motor 205 through a coupling. The motor 205 drives the conveying shaft 3 to rotate, so that the conveying shaft 3 drives the spiral blade 301 to rotate. The spiral blade 301 conveys the aluminum waste that enters the continuous feeding device 2 from the feed port 203. After being conveyed, the aluminum waste falls through the discharge port 201 and is guided into the furnace through the discharge hopper 202.

[0026] Furthermore, a blocking net 402 is fixedly connected to the upper middle end of the dust suction port 401, and an inclined plate 404 is provided at the lower end of the trapezoidal air guide cover 403. The lower end of the inclined plate 404 is inserted into the lower end surface of the dust suction port 401 and fixedly connected. The blocking net 402 is used to block the aluminum waste when it is put into the feeding hopper 4 to prevent the aluminum waste from flying into the suction pipe 501.

The purified gas is discharged through the exhaust pipe 602.

[0029] Working principle: When in use, first inject the filtrate into the filter box 6, put the aluminum waste into the feeding hopper 4, and enter the continuous feeding device 2 through the feeding port 203. The conveying shaft 3 is driven by the motor 205 to rotate, so that the conveying shaft 3 drives the spiral blade 301 to rotate, and the spiral blade 301 will convey the aluminum waste that enters the continuous feeding device 2 from the feeding port 203. After being conveyed, the aluminum waste falls through the discharge port 201 and is guided into the furnace through the discharge hopper 202. The upper end of the middle part of the dust suction port 401 is fixedly connected with a blocking net 402, and the lower end of the trapezoidal air guide cover 403 is provided with an inclined plate 404. The lower end of the inclined plate 404 is inserted into the lower end surface of the dust suction port 401 and is fixedly connected. When waste is put into the feeding hopper 4, it is blocked to prevent aluminum waste from flying into the suction pipe 501. The aluminum waste that jumps into the trapezoidal air guide cover 403 is guided back to the feeding hopper 4 through the dust suction port 401 through the inclined plate 404. When aluminum waste is fed into the feeding hopper 4, the smoke generated during feeding is sucked from the dust suction port 401 by the suction fan 5 connected to the trapezoidal air guide cover 403 through the suction pipe 501. The smoke sucked by the suction fan 5 is sent to the lower end of the filter box 6 through the exhaust pipe 502. After the smoke enters the lower end of the filter box 6, the air pressure rises and it is dispersed into bubbles through the dense circular holes on the bubble generating plate 601, so that the smoke is fully in contact with the filtrate for purification. The purified gas is discharged through the exhaust pipe 602.
