[0026] The power provided by the driving motor 5 is transmitted through the power component 4 to rotate the external drum 11 inside the drum component 1. At the same time, the electromagnet activated by the power supply imparts magnetic force to it, so as to magnetically select metal particles. The screened metal particles are transported out through the feeding component 2, and the waste materials without metal are discharged through the discharge port 13.

[0027] See also Figure 2 The power assembly 4 includes a rotating internal gear 41, the rear end of which is rotatably connected to the outer side of the front end of the drum assembly 1, and the built-in drum 12 fixedly connected at the rear end is driven to rotate by the rotating internal gear 41. At the same time, a rotating external gear 42 is meshed inside the rotating internal gear 41, and the rear end of the rotating external gear 42 is fixedly connected to the front end of the drum assembly 1. Two bevel gears 43 are arranged in parallel at the front and rear of the rotating external gear 42. The top end of the upper bevel gear 43 is fixedly connected to the bottom of the driving motor 5. The power provided by the driving motor 5 is provided to the rotating external gear 42 through the steering of the bevel gear 43, so that the rotating external gear 42 rotates the rotating internal gear 41.

[0028] See also Figure 2 The machine bracket 3 includes two device brackets 31. The device brackets 31 are trapezoidal. A groove with an arc equal to that of the feeding pipe 21 is opened at the top of the rear device bracket 31, and the groove is fixedly connected to the bottom end of the feeding pipe 21. A groove with an arc equal to that of the rotating pipe 62 is opened at the top of the front device bracket 31, and the groove is fixedly connected to the bottom end of the rotating pipe 62. The device as a whole is cylindrical, and the bracket with an arc-shaped groove can better support the device.

[0030] See also Figure 3 The feeding pipe 21, the limiting pipe 22 and the feeding rotary column 23 are all located inside the built-in drum 12. A waste hole is provided at the bottom of the built-in drum 12. When the built-in drum 12 is rotating and magnetically separating, the metal particles separated by the magnetic separation will fall into the feeding pipe 21, and the waste after the magnetic separation will enter the external drum 11 through the waste hole, and then flow out of the device through the discharge port 13.

[0031] See also Figure 3 and Figure 4 The feeding tube 21, the limiting tube 22 and the feeding rotary column 23 are of the same length, the bottom end of the feeding rotary column 23 is close to the lower end of the inside of the feeding tube 21, and a gap is left between the lower end of the limiting tube 22 and the lower end of the feeding tube 21. The length of the feeding tube 21, the limiting tube 22 and the feeding rotary column 23 can ensure the completeness of the material transportation work. The metal particles after magnetic separation will pass through the groove at the top of the feeding tube 21 and fall into between the feeding tube 21 and the limiting tube 22, and then enter the limiting tube 22 through the gap between the limiting tube 22 and the bottom end of the feeding tube 21, and be pushed by the feeding rotary column 23 to be transported to the rear end. The limiting tube 22 wraps the feeding rotary column 23 with a large area to prevent the metal particles from being squeezed out during the operation of the feeding rotary column 23.

[0032] See also Figure 3 and Figure 4 The feeding assembly 2 includes a feeding rotary column 23, the front end of which is fixedly connected to the rear end of the injection port 61. The rotating external gear 42 will drive the injection port 61 to rotate, and the injection port 61 will drive the feeding rotary column 23 to rotate to achieve the purpose of feeding. The outer surface of the feeding rotary column 23 is rotatably connected to the limiting tube 22. Two fixed columns are provided on the outer surface of the limiting tube 22. The ends of the two fixed columns away from the limiting tube 22 are fixedly connected to the feeding tube 21. Grooves are penetrated at the top end of the feeding tube 21 and the bottom end of the limiting tube 22. The material after magnetic separation falls into the limiting tube 22 through the groove at the top end of the feeding tube 21, and then enters the working range of the feeding rotary column 23 through the groove at the bottom end of the limiting tube 22.

[0033] See also Figure 5 and Figure 6The feed port 6 includes an injection interface 64, the rear end of the injection interface 64 passes through the middle of the lower bevel gear 43, the rear end of the injection interface 64 is fixedly connected to a horizontal bearing 63, the rear end of the injection interface 64 is fixedly connected to a one-way valve toward the rear end, the outer surface of the horizontal bearing 63 is rotatably connected to a rotating pipe 62, the rear end of the rotating pipe 62 passes through the rotating external gear 42 and is fixedly connected to an injection port 61, the rotating pipe 62, the horizontal bearing 63 and the middle of the injection interface 64 are all penetrated by pipes that pass through the inside of the injection port 61, a groove is opened in the middle of the outer surface of the horizontal bearing 63, a number of rolling balls are arranged in the groove, the rolling balls are all tightly attached to the inner wall of the rotating pipe 62, and a number of holes are opened on the outer surface of the injection port 61 to connect to the middle pipe.

[0034] Because the bevel gear 43 will drive the rotating pipe 62, the rotating external gear 42, and the injection port 61 to rotate, the horizontal bearing 63 provided therein can keep the injection interface 64 connected to the air from rotating, so that the feeding can be carried out more stably, and the incoming raw materials will pass through the horizontal bearing 63, the rotating pipe 62, and the rotating external gear 42 in turn, and when reaching the injection port 61, they will enter the interior of the built-in drum 12 through the hole opened on the outer surface of the injection port 61 for magnetic separation.

[0035] Working principle:

[0036] First, connect the raw material conveying pipe to the front end of the injection interface 64, then connect the power supply to give electromagnetic magnetic force to the built-in drum 12, start the drive motor 5, and rotate the built-in drum 12 through the transmission of the power component 4. When the raw material passes through the one-way valve inside the injection interface 64 and the feed port 6 to reach the injection port 61, it enters the built-in drum 12 through the hole opened on the surface, and the magnetic separation process is carried out in the built-in drum 12. The metal particles will be adsorbed on the inner wall of the built-in drum 12 due to the magnetic force of the built-in drum 12. When the built-in drum 12 rotates to reach the high non-magnetic area, it falls into the groove of the feeding pipe 21 by gravity, and then is output from the rear end through the feeding of the feeding rotary column 23, completing the magnetic separation process, and the magnetically separated waste will flow out of the device through the discharge port 13.
