Description

Technical Field

[0001] The invention relates to the technical field of rare earth processing equipment, in particular to rare earth magnetic filtering treatment equipment for rare earth processing. Background Art

[0002] Rare earths have irreplaceable excellent magnetic, optical and electrical properties, which play a huge role in improving product performance, increasing product variety and improving production efficiency. After being mined, rare earth elements usually exist in the form of oxides, phosphates or carbonates. Therefore, if you want to obtain rare earths from rare earth ores, you need to smelt the ores, and there will be a lot of impurities in the ores. Therefore, before smelting rare earth ores, it is necessary to separate the rare earth-containing substances from the impurities.

[0003] For example, the Chinese patent with publication number "CN118976594A" discloses "a magnetic rare earth filter device for rare earth processing", whose main structure includes a bottom plate; a support leg fixedly mounted on the top of the bottom plate; a filter box fixedly mounted on the top of the support leg; and a filter assembly arranged on the filter box. The magnetic rare earth filter device for rare earth processing rotates the reciprocating screw to make the moving plate reciprocate left and right along the reciprocating screw, thereby driving the L-shaped rack to move left and right. The left and right movement of the L-shaped rack causes the gear to reciprocate forward and reverse, thereby driving the rotating shaft to periodically rotate forward and reverse, thereby driving the filter plate to shake, The rare earth accumulated on the filter plate 1 is shaken apart, so that the magnetic rare earth contacts with the magnetic rod 1 and is then adsorbed by the magnetic rod 1. At the same time, shaking left and right avoids the problem of the rare earth flipping quickly and causing the magnetic rare earth on the magnetic rod 1 to be rubbed off. At the same time, the filter plate 1 filters out the debris in the rare earth. When the support shaft 1 is driven by the filter plate 1 to move along the arc groove 1, it drives the fixed sleeve 1 to move. The movement of the fixed sleeve 1 drives the fixed sleeve 2 to move through the hinged rod, and then drives the support shaft 2 to move. The movement of the support shaft 2 drives the filter plate 2 to shake left and right, and then the magnetic rare earth that has not been adsorbed in the primary filter part is adsorbed for the second time, thereby ensuring the filtering effect of the rare earth.

[0004] However, when the above-mentioned magnetic rare earth filtration device for rare earth processing is actually used, the magnetic substances in the rare earth solution will be adsorbed onto the surfaces of magnetic rod one and magnetic rod two. After the filtration is completed, due to the magnetic attraction, the magnetic substances on the surfaces of magnetic rod one and magnetic rod two will be difficult to separate, and most of the magnetic substances are relatively small particles, making it more difficult to collect them. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a rare earth magnetic filtration processing equipment for rare earth processing, which utilizes a slowly rotating magnetic rod to perform an adsorption-type separation effect on magnetic objects in a rare earth solution.
