The connecting component includes a groove 11, the groove 11 is opened on the outer wall of the cylinder body 1, a first rotating shaft 12 and a second rotating shaft 13 are rotatably installed between the inner walls of the groove 11 through bearings. A first semi-circular plate 14 is fixedly sleeved on the first rotating shaft 12, a second semi-circular plate 15 is fixedly sleeved on the second rotating shaft 13. A first fixing block 16 is welded on the top side of the first semi-circular plate 14, a second fixing block 17 is welded on the top side of the second semi-circular plate 15. An axial hole 18 is opened at the center of the cylinder cover 2, an installation groove 19 is opened inside the axial hole 18, a flange 20 is installed in the installation groove 19, and a transmission shaft 21 is installed in the flange 20; during operation, in the process of sealing the cylinder body 1 by the existing sealing device, the cylinder body 1 and the cylinder cover 2 are fixedly installed by using stainless steel screws. Since the sealing ring 10 needs to be inspected and replaced regularly, the stainless steel screws need tools for disassembly, resulting in low disassembly efficiency. By covering the cylinder cover 2 on the cylinder body 1 and placing the sealing ring 10 between the cylinder body 1 and the cylinder cover 2, the sealing of the inside of the cylinder body 1 is realized, and impurities or ore powder are prevented from entering the inside of the magnetic separator cylinder body 1;

[0019] During the installation of the cylinder body 1 and the cylinder head 2, first open the first semi-circular plate 14 and the second semi-circular plate 15, then align the locking components and connection components on the cylinder body 1 and the cylinder head 2. At this time, the push plate 8 on the cylinder head 2 can directly pass through between the first semi-circular plate 14 and the second semi-circular plate 15. Then hold the first fixing block 16 and the second fixing block 17 to merge the first semi-circular plate 14 and the second semi-circular plate 15 into a circular structure. At this time, rotate the knob 7 to drive the screw rod 6 to rotate. While the screw rod 6 rotates on the rod seat 4, it also moves horizontally. The screw rod 6 drives the push plate 8 to move towards the first semi-circular plate 14 and the second semi-circular plate 15, adjust the position of the push plate 8 so that the two groups of limit plates 9 are located on both sides of the first semi-circular plate 14 and the second semi-circular plate 15.

By covering the cylinder cover 2 on the cylinder body 1 and placing the sealing ring 10 between the cylinder body 1 and the cylinder cover 2, the sealing of the inside of the cylinder body 1 is achieved, avoiding impurities or ore powder from entering the inside of the magnetic separator cylinder body 1; during the installation process of the cylinder body 1 and the cylinder cover 2, by first opening the first semi-circular plate 14 and the second semi-circular plate 15, then aligning the locking components and connecting components on the cylinder body 1 and the cylinder cover 2. At this time, the push plate 8 on the cylinder cover 2 can directly pass through between the first semi-circular plate 14 and the second semi-circular plate 15. Then, hold the first fixing block 16 and the second fixing block 17 to make the first semi-circular plate 14 and the second semi-circular plate 15 combine into a circular structure. At this time, rotate the knob 7 to drive the screw rod 6 to rotate. While the screw rod 6 rotates on the rod seat 4, it also moves horizontally. The screw rod 6 drives the push plate 8 to move towards the first semi-circular plate 14 and the second semi-circular plate 15, adjusting the position of the push plate 8 so that the two groups of limit plates 9 are located on both sides of the first semi-circular plate 14 and the second semi-circular plate 15. The screw rod 6 drives the push plate 8 to continue moving until the push plate 8 is in contact with the first semi-circular plate 14 and the second semi-circular plate 15. The push plate 8 pushes the first semi-circular plate 14 and the second semi-circular plate 15 to closely adhere to the cylinder cover 2, and the first semi-circular plate 14 and the second semi-circular plate 15 drive the cylinder body 1 to closely adhere to the cylinder cover 2, achieving the fixed installation of the cylinder body 1 and the cylinder cover 2; when disassembling the cylinder body 1 and the cylinder cover 2, only need to rotate the knob 7 in the reverse direction, the screw rod 6 drives the push plate 8 to move away from the first semi-circular plate 14 and the second semi-circular plate 15, and then the first semi-circular plate 14 and the second semi-circular plate 15 are opened, achieving the rapid disassembly of the cylinder body 1 and the cylinder cover 2.
