[0018] like Figure 1 and Figure 2 As shown, the fully enclosed downstream permanent magnet drum separator includes: a housing 1, a protective cover 2, a drum 3, a magnet 4, a magnet shaft 41, a feed inlet 5, a magnetic separation plate 6, a frame plate 61, a non-magnetic discharge outlet 7, a trough 8, a magnetic metal discharge outlet 9, a frame 10, a transmission assembly 11, an observation window 12, and a water spray device 13.

[0019] refer to Figure 2 The protective cover 2 is installed on top of the housing 1, forming a closed chamber. The middle crossbeam of the frame 10 is bolted to the housing 1, ensuring that the housing 1 is installed on top of the frame 10. These three components constitute the main body of this design, and the metal frame 10 provides support for the equipment. The protective cover 2 blocks splashes generated during equipment operation, preventing injury from contact with the human body. The sealed design prevents dust diffusion. The protective cover 2 is removable for easy maintenance, and has an observation window 12 on the cover plate for real-time monitoring of equipment operation. Permanent magnet drums are installed inside the housing 1 and on the frame 10. The permanent magnet drum is the core component of magnetic separation. It consists of a drum 3, a magnet 4, a magnet shaft 41, and a magnetic system adjustment device. The magnet 4 is installed inside the housing 1, and the drum 3 is rotatably installed inside the housing 1, with the drum 3 located outside the magnet 4. The drum 3 uses a double-layer shell structure for easy replacement and to increase the service life of the equipment. Magnet 4 is designed with a C-shaped arc and its opening faces upward. Its performance is specifically tailored for slag materials, utilizing high-performance, high-coercivity ferrite and rare-earth neodymium iron boron magnetic materials to effectively attract and separate ferrous materials from the slag. A magnet shaft 41 is connected to one side of magnet 4 via a mounting plate. Magnet shaft 41 is coaxial with magnet 4 and extends through and beyond the outer side of the housing 1. A bearing seat can be additionally installed on the frame 10, supporting magnet shaft 41. A magnetic system adjustment device is mounted on the frame 10 to drive magnet 4 to rotate, allowing for fine-tuning and ensuring the magnetic system is in a suitable working position, thus improving the sorting effect.

[0020] In addition, a feed inlet 5 is provided on the housing 1, and a magnetic separator 6 is installed inside the housing 1. The magnetic separator 6 is located at the bottom of the feed inlet 5, and its main body is arc-shaped and coaxial with the roller 3. A gap is left between the magnetic separator 6 and the roller 3. The magnetic separator 6 is made of stainless steel plate or wear-resistant steel plate and is installed with screws. The installation gap distance is set according to the actual needs. The surface is smoothly polished to make the material flow smoother and prevent blockage. The magnetic separator 6 is provided with a non-magnetic discharge port 7, the bottom end of which extends out of the bottom end of the housing 1 for discharging non-magnetic metal materials. A trough 8 is installed on the housing 1 for collecting magnetic metals. A retaining plate 61 is provided at the end of the magnetic separator 6 facing the trough 8. The retaining plate 61 is inclined from top to bottom towards one side of the trough 8 to guide the falling magnetic metals into the trough 8. A magnetic metal discharge port 9 is provided at the bottom end of the trough 8 for discharging magnetic metals. A water spray device 13 is installed inside the protective cover 2. The water spray device 13 consists of a main water pipe and nozzles. The main water pipe extends out of the protective cover 2 and is connected to an external water tank. Turning on the external water pump allows water to be sprayed out through the nozzles, which face the roller 3 to wash the roller 3, thus aiding in the magnetic metal stripping process. The nozzles in the water spray device 13 use fan-shaped nozzles to spray water, achieving large-area uniform coverage through fan-shaped spray.

[0021] refer to Figure 3 , Figure 4 and Figure 5 The transmission assembly includes a motor 1101, a reducer 1102, pulleys 1103, and a belt 1104. Both the motor 1101 and the reducer 1102 are mounted on the frame 10. There are two pulleys 1103, one mounted on the output end of the motor 1101 and the other on the input end of the reducer 1102. The two pulleys 1103 are connected by a tensioned belt 1104 to ensure synchronous rotation of the two pulleys 1103. The output end of the reducer 1102 is connected to the center of the roller 3.

[0022] In actual use, the motor 1101 is turned on, and the reducer 1102 is started and operated through the cooperation of the pulley 1103 and the belt 1104, which in turn drives the drum 3 to rotate. Slag enters the space between the magnetic separator 6 and the drum 3 through the feed inlet 5. The slag moves along the arc surface of the magnetic separator 6, and the direction of movement of the slag is consistent with the rotation direction of the drum 3. Because the magnet 4 is magnetic, its part opposite to the drum 3 forms a strong magnetic area, and magnetic metals are attracted to the surface of the drum 3 and follow its rotation. Non-magnetic metals are discharged through the non-magnetic discharge outlet 7. As the drum 3 rotates, the magnetic metals move to a position that does not correspond to the magnet 4 and enter the weak magnetic area. The non-magnetic metals are then dislodged by their own weight and the action of the flushing water, and guided by the guide plate 61 into the tank 8. It is worth noting that in this embodiment, the highest point of the magnet 4 is lower than the horizontal center line of the drum 3, and the highest point of the guide plate 61 corresponds to the highest point of the magnet 4. This ensures that the magnetic metal enters the weak magnetic region before crossing the center line of roller 3, preventing the magnetic metal from rotating with roller 3 for more than one revolution.

[0023] refer to Figure 6 and Figure 7 The magnetic system adjustment device includes: a lead screw 14, a nut 141, a moving block 15, a lever 16, a connecting frame 17, and a through slot 18. The lead screw 14 is threadedly mounted on the frame 10. There are two nuts 141, both threaded onto the lead screw 14, located on opposite sides of the frame 10. Rotating the lead screw 14 allows it to move along its axial direction, and adjusting the two nuts 141 further locks the position of the lead screw 14. The moving block 15 is mounted on the end of the lead screw 14 facing the center of the housing 1 via a bearing, and a slot is formed on the moving block 15. The lever 16 is installed in the slot of the moving block 15. The top of the connecting frame 17 is attached to the magnet shaft 41, and the bottom of the connecting frame 17 extends into the slot of the connecting frame 17. The through slot 18 is formed at the bottom of the connecting frame 17, and the lever 16 is installed in the through slot 18. In actual use, first rotate the lead screw 14 to move it axially, adjust the position of the moving block 15, and then use the cooperation of the lever 16 and the through slot 18 to make the connecting frame 17 swing, thereby driving the magnet shaft 41 to rotate, and finely adjust the position of the magnet 4. Then stop rotating the lead screw 14 and use the nut 141 to lock the position.
