In this process, the first motor will drive the magnetic selection cylinder to rotate through the gear set. The magnetic selection cylinder has a permanent magnet. The magnetic selection cylinder will adsorb the magnetic impurities in the raw material. The magnetic selection cylinder will continuously adsorb the magnetic impurities on the magnetic selection cylinder during rotation. When the magnetic selection cylinder rotates to the scraper, the scraper will scrape off the magnetic impurities adsorbed on the magnetic selection cylinder.

[0027] This application provides a high-efficiency magnetic separation device for white fused alumina, effectively solving the problem of the aforementioned impurity removal device. The magnetic separation mechanism inside the impurity removal cylinder filters magnetic impurities. However, in the magnetic separation process, the white fused alumina raw material must first be poured into the cylinder, and after magnetic separation, the white fused alumina and magnetic impurities are poured out separately before a second magnetic separation can be performed, resulting in low efficiency. The raw material enters the outer cylinder through the feed hopper and is then discharged from the other side of the outer cylinder. During this process, the first motor starts and drives the magnetic separation cylinder to rotate via a gear set. The magnetic separation cylinder contains permanent magnets, which attract magnetic impurities from the raw material. As the cylinder rotates, it continuously attracts magnetic impurities. When the magnetic separation cylinder rotates to the scraper, the scraper will remove... Magnetic impurities adsorbed on the magnetic separator are scraped off. The continuous rotation of the magnetic separator continuously draws out these impurities, while the side of the outer cylinder continuously discharges the screened white fused alumina. This continuous magnetic separation improves work efficiency. The second motor starts, driving the transmission disc to rotate. The transmission disc then drives the slider to rotate. Since the slider is slidably connected to the rocker arm, the slider's rotation causes the rocker arm to swing, which in turn causes the outer cylinder to swing. This swinging motion of the outer cylinder ensures a more even distribution of the white fused alumina material inside, resulting in better magnetic separation. Furthermore, the left-right swinging of the outer cylinder facilitates the discharge of the material inside, preventing it from accumulating and getting stuck between the outer cylinder and the magnetic separator. This not only improves the magnetic separation effect but also facilitates the discharge of the magnetically separated white fused alumina.

[0028] Example

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the technical solution in this application embodiment effectively solves the problem of the aforementioned impurity removal device. Magnetic impurities are screened through a magnetic separation mechanism inside the impurity removal cylinder. However, during the magnetic separation process, the white corundum raw material needs to be poured into the impurity removal cylinder first. After the magnetic separation is completed, the white corundum and magnetic impurities are poured out separately before a second magnetic separation can be performed. Therefore, this results in low working efficiency. The overall approach is as follows:

[0030] To address the problems existing in the prior art, this utility model provides a high-efficiency magnetic separation iron removal device for white corundum, including a support frame 1, an outer cylinder 2 rotatably mounted inside the support frame 1, a magnetic separation cylinder 3 for magnetic separation rotatably mounted inside the outer cylinder 2, a scraper 4 for cleaning the magnetic separation cylinder 3 fixedly mounted on the side end of the outer cylinder 2, and a first motor 5 fixedly mounted on the outer cylinder 2.

[0031] A gear set 6 for transmitting power is installed between the first motor 5 and the magnetic separator 3. A feed hopper 7 for feeding is fixedly installed on the side of the support frame 1. A permanent magnet is installed inside the magnetic separator 3, and a second motor 8 is fixedly installed on the support frame 1.

[0032] A rocker arm 9 for transmitting power is rotatably mounted on the support frame 1; the rocker arm 9 is fixedly connected to the outer cylinder 2; a transmission disk 11 is fixedly mounted on the shaft of the second motor 8; a slider 12 is slidably mounted on the rocker arm 9; and the slider 12 is rotatably connected to the transmission disk 11.

[0033] Support frame 1: Serves as the main frame of the device, providing a foundation for the installation and support of other components;

[0034] Outer cylinder 2: The two ends of the outer cylinder 2 are provided with openings for the entry and exit of white fused alumina. The interior contains the white fused alumina after magnetic separation and discharge treatment of the raw material. It can also promote the uniform distribution and discharge of the raw material when swinging.

[0035] Magnetic separator 3: It is equipped with permanent magnets inside, which adsorb magnetic impurities in the raw materials by rotating.

[0036] Scraper 4: Used to scrape off magnetic impurities adsorbed on the magnetic separator 3;

[0037] First motor 5: provides power and drives the magnetic separator 3 to rotate through gear set 6;

[0038] Gear set 6: It consists of two meshing gears, which are respectively connected to the rotating shaft of the first motor 5 and the magnetic separator 3, and transmit the power of the first motor 5 to the magnetic separator 3 to realize the rotation of the magnetic separator 3;

[0039] Feed hopper 7: Used for feeding, allowing unselected raw materials to enter the outer cylinder 2;

[0040] Second motor 8: After starting, it drives the transmission disc 11 to rotate, providing a power source for the operation of subsequent components;

[0041] Joystick 9: During the swinging process, it drives the outer cylinder 2 to swing;

[0042] Transmission disc 11: Driven to rotate by the second motor 8, which in turn drives the slider 12 to rotate;

[0043] Slider 12: When rotating, the sliding connection with the rocker arm 9 causes the rocker arm 9 to swing.

[0044] Working principle:

[0045] The first step involves connecting the feeding mechanism to the feed hopper 7. The feeding device will then feed the unselected raw material into the feed hopper 7. The raw material will then enter the outer cylinder 2 along the feed hopper 7 and be discharged from the other side of the outer cylinder 2. During this process, the first motor 5 will start and drive the magnetic separator 3 to rotate through the gear set 6. The magnetic separator 3 contains a permanent magnet, which will adsorb magnetic impurities in the raw material. As the magnetic separator 3 rotates, it will continuously adsorb magnetic impurities onto the magnetic separator 3. When the magnetic separator 3 rotates to the scraper 4, the scraper 4 will scrape off the magnetic impurities adsorbed on the magnetic separator 3. The magnetic separator 3 will continuously rotate and continuously draw out magnetic impurities. At the same time, the side end of the outer cylinder 2 will continuously discharge the screened white corundum. Continuous magnetic separation is carried out, which improves the working efficiency.

[0046] In the second step, simultaneously, the second motor 8 starts and drives the transmission disk 11 to rotate. The transmission disk 11 will drive the slider 12 to rotate. Since the slider 12 is slidably connected to the rocker arm 9, the slider 12 will drive the rocker arm 9 to swing during the rotation. The rocker arm 9 will cause the outer cylinder 2 to swing. During the swinging process, the white corundum raw material entering the outer cylinder 2 can be distributed more evenly, making the magnetic separation effect better. At the same time, the left and right swinging of the outer cylinder 2 is conducive to the discharge of the internal raw material, avoiding the accumulation of raw material between the outer cylinder 2 and the magnetic separation cylinder 3. This not only improves the magnetic separation effect, but also facilitates the discharge of the white corundum after magnetic separation.

[0047] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
