[0002] High-purity red iron oxide is one of the important raw materials for the production of color TV glass shells in the modern electronics industry. According to national standards for premium products, red iron oxide must be above 99.20% to be considered high-purity red iron oxide. To obtain stable ultra-high-purity red iron oxide, solid iron oxide powder purification technology must be used. Based on the properties of iron oxide and the principles of ion exchange, calcium, magnesium, zinc, and copper are removed under acidic conditions. In particular, a redox method is used to remove impurities such as manganese with high content. Subsequently, iron oxide is used as a carrier and ion exchange is used to remove impurities such as sulfate, thus refining high-purity iron oxide.

[0003] The traditional magnetic separation device for purifying high-purity iron oxide powder has a magnetic roller installed in the frame. The motor drives the magnetic roller to rotate. The high-purity iron oxide powder is poured into the hopper, and the high-purity iron oxide powder flows through the hopper to the surface of the magnetic roller to achieve magnetic separation of the high-purity iron oxide powder. In order to prevent too much high-purity iron oxide powder from falling on the surface of the magnetic roller at the same time and affecting the magnetic separation effect, a filter is installed at the upper end of the hopper to disperse the high-purity iron oxide powder.

[0004] This type of magnetic separation device for purifying high-purity iron oxide powder has the following disadvantages: when purifying high-purity iron oxide powder, it is necessary to manually add materials to the hopper continuously, which wastes labor resources.

The first motor 2 drives the magnetic roller 6, and the second motor 59 drives the cam 57 to rotate through the rotating rod 11. After being shaken into the upper end of the magnetic roller 6, the magnetic roller 6 will adsorb the iron powder on the surface, and the substances that cannot be adsorbed will be shaken off to the upper end of the slag hopper 8 and finally flow out of the frame. The adsorbed iron powder will be scraped off by the scraper 10 to the discharge hopper 9 and fall outside the frame 1, thus completing the purification of high-purity iron oxide powder;

[0022] Feeding mechanism 5: It includes a mounting seat 51, a guide column 52, a rocking seat 54, a slide column 55, a rocking block 56 and a feeding hopper 58. The middle part of the lower end of the feeding seat 4 is provided with symmetrically distributed mounting seats 51. The opposite inner sides of the two mounting seats 51 are slidably connected with evenly distributed guide columns 52. The side of the guide column 52 close to the center of the mounting seat 51 is fixedly connected to the outer surface of a rocking seat 54. The front and rear sides of the rocking seat 54 are both provided with slide columns 55. The slide columns 55 are connected to a rocking block 56. The block 56 is slidably connected, and the upper end of the rocking block 56 is fixedly connected to the feeding hopper 58.

The springs 53 are all arranged between the mounting seat 51 and the rocking seat 54. The feeding mechanism 5 also includes a cam 57 and a second motor 59. The cam 57 is rotatably connected to the middle of the right side of the rocking block 56 through the rotating shaft 12.

The input end of the second motor 59 is electrically connected to the output end of the control switch group 3. At this time, the cam 57 rotates with the rotating rod 11 as the center of the circle, and drives the rocking block 56 to revolve. When the cam 57 rotates clockwise, the rocking block 56 slides upward along the sliding column 55, thereby generating an upward shaking force and generating an extrusion force on the rocking seat 54, so that it pushes the guide column 52 to move inward in the mounting seat 51. After that, it slides, thereby generating a shaking force to the right. When the cam 57 rotates one circle, it will give the feeding hopper 58 a shaking force in all directions up and down and left and right.

[0023] The working principle of the magnetic separation device for purifying high-purity iron oxide powder provided by the present invention is as follows: if high-purity iron oxide powder needs to be purified, the high-purity iron oxide powder purification staff needs to first pour the high-purity iron oxide powder into the feeding hopper 58, and then turn on the first motor 2 and the second motor 59 through the control switch group 3. The first motor 2 drives the magnetic roller 6, and the second motor 59 drives the cam 57 to rotate through the rotating rod 11. At this time, the cam 57 rotates with the rotating rod 11 as the center of the circle, and drives the shaking block 56 to revolve. When the cam 57 rotates clockwise, the shaking block 56 slides upward along the sliding column 55, thereby generating an upward shaking force. , and generates an extrusion force on the rocking seat 54, causing it to push the guide column 52 to slide backward in the mounting seat 51, thereby generating a shaking force to the right. When the cam 57 rotates one circle, it will give the feeding hopper 58 a full range of shaking force up and down and left and right. In this way, the high-purity iron oxide powder on the feeding hopper 58 will be shaken into the upper end of the magnetic roller 6. After shaking into the upper end of the magnetic roller 6, the magnetic roller 6 will adsorb the iron powder on the surface, and the material that cannot be adsorbed will be shaken off to the upper end of the slag hopper 8 and finally flow out of the frame. The adsorbed iron powder will be scraped off by the scraper 10 to the discharge hopper 9 and fall outside the frame 1, thus completing the purification of the high-purity iron oxide powder.
