Description

Technical Field

[0001] The invention relates to the technical field of rare earth metal recovery, and more particularly to a rare earth metal recovery device based on rare earth metal slag. Background Art

[0002] The rare earth metals in rare earth metal slag solutions are also called rare earth elements. They are the general term for 17 elements in the scandium, yttrium, and lanthanide series in Group IIIB of the periodic table. The luster of rare earth metals is between silver and iron. The impurity content has a great influence on their properties. To separate and extract a single rare earth element from a mixed rare earth compound solution, it is necessary not only to separate these dozen rare earth elements with extremely similar chemical properties, but also to separate the rare earth elements from the associated impurities. Therefore, in the industrial process, the process of extracting rare earth metals from rare earth metal slag solutions mainly includes chemical methods, ion exchange methods, and solvent extraction methods.

[0003] At present, when purifying and recovering rare earth metals in rare earth metal slag solutions, the ion exchange method is mostly used, in which the impurity ions in the rare earth metal slag solution are adsorbed by resin, thereby purifying the rare earth metals in the rare earth metal slag solution.

[0004] During the purification process, the existing equipment only relies on the gravity of the rare earth metal slag solution itself to adsorb impurity ions inside the resin, which causes the adsorption process of the impurity ions to be too slow. In addition, during the adsorption process, some solution that is not absorbed by the resin is easily retained inside the resin, resulting in the waste liquid remaining in the resin falling into the collection structure when the rare earth metal slag solution after purification and adsorption is collected later, thereby causing pollution to the purified solution.

[0060] Furthermore, an extension rod 509 is fixed at the bottom of the sliding plate 507, and a metal ball 510 is fixed at the bottom of the extension rod 509; two symmetrical L-shaped limit plates 310 are fixed to the top of the positioning ring plate 301, and two symmetrical arc-shaped vertical plates 311 are fixed to the top of the positioning ring plate 301 between the two L-shaped limit plates 310, and a driving motor 312 is fixed to the top of the positioning ring plate 301, and a gear 313 is fixed to the output shaft of the driving motor 312; the rotating member 6 includes a rotating cylinder 601, and a ring-shaped groove 602 that is rotatably matched with the two arc-shaped vertical plates 311 is opened at the bottom of the rotating cylinder 601, and a plurality of grooves 603 that are compatible with the metal balls 510 are opened at the top of the rotating cylinder 601, and a gear ring 604 that meshes with the gear 313 is fixed to the outer peripheral side of the rotating cylinder 601.

[0061] The specific application of this embodiment 1 is:

[0062] When the whole device is recycling waste liquid, the rare earth metal slag waste liquid to be recycled first passes through the preliminary filtering effect of the filter element 4 to filter out insoluble impurities in the rare earth metal slag waste liquid to be recycled, and then the rare earth metal slag waste liquid to be recycled after preliminary filtering passes through the filter element 4 into the guide cylinder 304, and the soluble impurities of the rare earth metal slag waste liquid after preliminary filtering are removed through the recovery component 2, so as to perform a later purification operation on the rare earth metal slag waste liquid, thereby increasing the recycling efficiency of the rare earth metal slag waste liquid;

[0063] When the rare earth metal slag waste liquid is subjected to preliminary filtration and subsequent purification operations, the drive motor 312 is started to drive the gear 313 fixed to the output shaft of the drive motor 312 to rotate, so that the gear ring 604 meshing therewith rotates circumferentially, thereby driving the annular rotating groove 602 provided at the bottom of the rotating cylinder 601 to rotate on the two arc-shaped vertical plates 311 (in the process of circumferential rotation, the rotating cylinder 601 is limited by the limiting effect of the two L-shaped limiting plates 310 to prevent the rotating cylinder 601 from shaking up and down and separating from the two arc-shaped vertical plates 311 during the rotation process). 1), and finally drives the whole rotating member 6 to perform circumferential circular motion. When the whole rotating member 6 performs circumferential circular motion, the plurality of grooves 603 provided on the top of the rotating cylinder 601 in the rotating member 6 will sequentially and reciprocally make sliding contact with the metal ball 510 fixed at the bottom of the extension rod 509.

The flexible sleeve is a prior art and is not shown in the figure and will not be elaborated on here). The air pressure inside the variable guide cylinder 304 is changed, so that the airflow passes through the recovery component 2, so that the solution that has not flowed out of the recovery component 2 will be accelerated to flow out under the action of the airflow, thereby improving the adsorption of other impurity ions in the rare earth metal slag waste liquid by the recovery component 2, and improving the purification process of the rare earth metals in the rare earth metal slag waste liquid.

After the plug hole 409 and the positioning hole 704 are synchronously separated from the plug rod 321 and the plug vertical rod 329, the filter element 4 and the recovery component 2 that are plugged and matched are sequentially pulled out, so as to replace the filter element 4 and the recovery component 2. The installation method between the components is simplified during the entire disassembly process, which brings certain convenience to the staff;

[0067] When it is necessary to install the replaced filter element 4 and the recovery component 2, the hinge seat 327 is pulled again, so that the hinge seat 327 slides inside the rectangular frame 326, and thereby the third spring 328 fixedly connected between the hinge seat 327 and the rectangular frame 326 is stretched, so that the lifting arm 325 hingedly matched between the hinge seat 327 and the connecting cross plate 324 is slowly pulled down, thereby driving the two plug-in rods 321 and the two plug-in vertical rods 329 fixed on the top of the Y-shaped movable plate 322 to slide downward synchronously, and then the recovery component 326 is moved downward. The discharging member 7 in the discharging member 2 and the purification member 8 fixed in the discharging member 7 are synchronously inserted from the bottom of the positioning annular plate 301 into the inside of the guide cylinder 304, until the purification cylinder 701 in the discharging member 7 and the positioning ring 330 are fitted together, and the annular sealing gasket 331 fixed on the top of the positioning ring 330 is engaged with the annular sealing groove 711 opened on the top of the purification cylinder 701 of the guide cylinder 304, thereby increasing the sealing performance of the clamping fit between the recovery component 2 and the guide cylinder 304, thereby ensuring that the liquid waste does not leak during the filtration and purification recovery process of the waste;

[0068] After the above recovery component 2 and the guide cylinder 304 are engaged, the articulated seat 327 is stopped from being pulled, so that the articulated seat 327 slides in the opposite direction inside the rectangular frame 326 with the elastic restoring force of the third spring 328, thereby driving the lifting arm 325 between the articulated seat 327 and the connecting horizontal plate 324 to slowly lift up, thereby driving the two plug-in vertical rods 329 to move upward synchronously, and finally plug-in and engage with the inside of the two positioning holes 704 respectively, so as to position and fix the recovery component 2 plugged and fixed at the bottom of the guide cylinder 304 after being plugged in;

[0069] When installing the filter element 4 at a later stage, first slide the arc-shaped card plate 401 in the filter element 4 into the arc-shaped card groove 314, so that the filter disc 406 fixedly plugged into the inner wall of the arc-shaped card plate 401 is synchronously slidably plugged into the arc-shaped groove 315. When the filter disc 406 fixedly plugged into the inner wall of the arc-shaped card plate 401 is synchronously slidably plugged into the arc-shaped groove 315, its two slide plates 408 synchronously pass through the two sliding grooves 320 respectively, and synchronously approach the end of the plug-in rod 321. When the chamfered structure provided on one side of the slide plate 408 and the dome structure provided on the top of the plug-in rod 321 contact each other, continue to slide and engage the arc-shaped card plate 401, so that the slide plate 408 generates an upward moving force on the plug-in rod 321, and thereby the Y-shaped movable plate 322 fixedly connected to the base is fixedly connected to the Y-shaped movable plate 322. The second spring 323 between the plates 319 generates a stretching force until the plug hole 409 moves to the top of the plug rod 321, and the plug rod 321 is plugged into the plug hole 409 under the reset action of the second spring 323, and finally the first U-shaped sealing gasket 403 fixed on one side of the two second ear plates 402 and the first U-shaped sealing groove 317 are snapped together, and the two first arcuate sealing gaskets 404 fixed on the inner wall of the arc-shaped card plate 401 and the two first arcuate sealing grooves 318 are snapped together to seal the gap of the filter element 4 after snapping, so as to prevent the waste liquid to be recycled from flowing out, and finally complete the detachable installation process of the entire filter element 4, which simplifies the installation method between the components during the entire installation process, and brings certain convenience to the staff;

[0070] After the preliminary filtration of the convex filter screen 407, the rare earth metal slag waste liquid flows into the resin cylindrical block 805 through the guide tube 304, and then passes through the purification and adsorption action of the resin cylindrical block 805, and finally flows into the receiving box slidably matched between the two guide grooves 333 through the discharge cover 705 for collection, thereby completing the preliminary filtration and the subsequent purification and adsorption process in the whole process. When the whole equipment is performing preliminary filtration and subsequent purification and adsorption on the rare earth metal slag waste liquid, the change of its internal airflow can timely clear the filter holes in the convex filter screen 407 to prevent the filter holes in the convex filter screen 407 from being blocked by larger insoluble impurities, and at the same time accelerate the flow speed of the rare earth metal slag waste liquid after the preliminary filtration in the resin cylindrical block 805, so that the rare earth metal slag waste liquid after the preliminary filtration is evenly sprinkled on the surface of the resin cylindrical block 805, preventing the occurrence of uneven stratification inside the resin cylindrical block 805, avoiding its influence on the subsequent purification operation, and improving the recovery efficiency of the rare earth metal slag waste liquid.
