[0024] A mounting base 12 is fixedly installed at the bottom of the nut 10, and a fixed base 13 is fixedly installed at the center of the top of the baffle 7. The two ends of the rotating part 11 are respectively rotatably set in the mounting base 12 and the fixed base 13. A first pin is set in the mounting base 12, and a second pin is set in the fixed base 13. The two ends of the rotating part 11 are respectively rotatably sleeved on the first pin and the second pin. The driving part includes an electric push rod 16, which is fixedly installed on the inner side wall of the slag collection tank 4. The driving end of the electric push rod 16 is fixedly connected to the push plate 5. A first solenoid valve 18 and a second solenoid valve 19 are respectively set at the bottom of the inner roller 2 and the outer roller 1. The first solenoid valve 18 and the second solenoid valve 19 are connected in cooperation.

[0025] In practice, the electric push rod 16 is turned on, causing the drive end of the electric push rod 16 to extend and drive the push plate 5 to slide in the slag collection tank 4. This pushes the waste material out of the second solenoid valve 19 to a designated position for collection. Then, the motor 9 is turned on, causing the drive shaft of the motor 9 to drive the bidirectional lead screw 8 to rotate, so that the two nuts 10 move closer to each other. This allows the rotating part 11 to rotate while pushing the baffle 7 downward, which can scrape off the waste material adhering to the surface of the push plate 5 and discharge it out of the second solenoid valve 19. This can improve the waste material discharge effect and thus improve the collection effect.

[0026] As a further implementation of the above technical solution: a sliding opening 14 is provided at the bottom of the fixed box 6, which is connected to the inside of the fixed box 6, and the rotating part 11 is slidably inserted into the sliding opening 14. This ensures that the rotating part 11 can slide normally, avoids motion interference, and also ensures that the nut 10 will not rotate with the bidirectional lead screw 8.

[0027] As a further implementation of the above technical solution: a vibration motor 15 is fixedly installed at the center of the top of the baffle 7. By turning on the vibration motor 15, the vibration motor 15 can generate vibration and transmit it to the baffle 7, which can shake down a small amount of waste material at the bottom of the baffle 7, thereby further improving the discharge effect.

[0028] As a further implementation of the above technical solution: a baffle 17 is fixedly installed inside the outer roller 1. The baffle 17 abuts against the push plate 5 and is used to block the waste material splashing through the slag discharge hole 3.

[0029] As a further implementation of the above technical solution, it also includes two frames 20, which are symmetrically arranged. The two ends of the outer roller 1 are respectively rotatably mounted on opposite sides of the two frames 20. A servo motor 21 is provided on one side of one of the frames 20, and the drive shaft of the servo motor 21 is fixedly connected to one end of the outer roller 1. The magnetic material and metal grinding balls are fed into the inner roller 2 through the second solenoid valve 19 and the first solenoid valve 18. Then, the servo motor 21 is turned on, causing the outer roller 1 to drive the inner roller 2 to rotate. This facilitates the friction and compression of the metal grinding balls and magnetic material to break them into small pieces. The first solenoid valve 18 is then turned on, allowing the ground magnetic material to be discharged through the first solenoid valve 18 and the second solenoid valve 19, thus completing the processing.

[0030] Working principle:

[0031] Before using this invention, all electrical components of the tumbling mill and its waste collection device should be connected to an external power source to ensure their normal operation. During use, the magnetic material and metal grinding balls are fed into the inner drum 2 through the second solenoid valve 19 and the first solenoid valve 18. Then, the servo motor 21 is turned on, causing the outer drum 1 to rotate, which allows the metal grinding balls to rub and squeeze the magnetic material, breaking it into small pieces. If the magnetic material is broken into excessively small particles during this process, it can leak into the outer drum 1 and the slag collection trough 4 through the slag discharge hole 3. When waste needs to be collected after processing, the second solenoid valve 19 is turned downwards, and then the electric push rod 16 is activated, causing the electric push rod to... The extension of the drive end of rod 16 causes push plate 5 to slide in the slag collection trough 4, which can push the waste to be discharged from the second solenoid valve 19 to a designated position for collection. Then, the motor 9 is turned on, causing the drive shaft of the motor 9 to drive the bidirectional lead screw 8 to rotate, so that the two nuts 10 are brought closer to each other. This allows the rotating part 11 to rotate while pushing the baffle 7 downward, which can scrape off the waste adhering to the surface of push plate 5 and discharge it from the second solenoid valve 19, thereby improving the waste discharge effect and thus improving the collection effect. Finally, by turning on the vibration motor 15, the vibration motor 15 can generate vibration and transmit it to the baffle 7, which can shake off a small amount of waste at the bottom of the baffle 7, further improving the discharge effect.

[0032] Finally, following the principle described above, opening the first solenoid valve 18 allows the polished magnet to be discharged through the first solenoid valve 18 and the second solenoid valve 19, thus completing the processing.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
