As an important strategic resource, the supply and demand of rare earths have a significant impact on the country's economy and security. Although rare earths are relatively abundant on the earth, the amount of high-quality rare earth resources that can be mined is decreasing. Therefore, recycling and reusing rare earth waste has become a key measure to meet market demand and ensure the sustainable use of resources.

A driving deflection column 53 is rotatably arranged in the rotating installation cavity 56 directly facing the upper end of the material collecting conduit 47. A rotating scraper 54 is arranged on the driving deflection column 53 directly facing the wall of the rotating installation cylinder 28. The rotating scraper 54 is matched with the inclined auxiliary magnetic attraction ring 52 to be provided with a plurality of inclined notches 55. A liquid storage chamber 38 is arranged in the support mounting tube 14 and the curved surface mounting cover 11 on one side of the drop tube 36, and a plurality of guide tubes 39 are arranged at the bottom of the liquid storage chamber 38, and the two ends of the guide tubes 39 are respectively connected to the liquid storage chamber 38 and the mixing chamber 29, and a valve body 40 is arranged inside the guide tubes 39; a connecting conduit 12 extending out of the support mounting tube 14 is arranged on the liquid storage chamber 38.

[0039] Specifically, the rare earth waste is poured from the open cambered guide barrel 15, and enters the working installation barrel 13 under the guiding action of the cambered guide installation plate 16 and the open cambered guide barrel 15, and the rare earth waste enters the variable diameter crushing groove 44 and the rotating grinding groove 45 in turn. At the same time, the driving member 2 43 drives the variable diameter crushing column 23 and the rotating grinding column 25 to rotate synchronously. While the rare earth waste is guided downward along the variable diameter crushing groove 44, the variable diameter crushing column 24 of the variable diameter crushing groove 44 and the variable diameter crushing column 24 on the variable diameter crushing column 23 rotate relatively to crush the rare earth waste falling therein, and the crushing accuracy is gradually improved from top to bottom, and finally the rare earth waste is guided out from the bottom of the variable diameter crushing groove 44 into the rotating grinding groove 45. The rare earth waste entering the rotating grinding groove 45 enters the conical guide groove 26 after grinding under the rotating grinding action of the rotating grinding column 25 and the rotating grinding groove 45, and is introduced into the inclined guide pipe 27. As more and more rare earth waste is ground in the inclined guide tube 27, it exceeds the bearing limit of the reset discharge tray 35. At this time, the reset discharge tray 35 rotates, and the rare earth waste ground in the inclined guide tube 27 and the conical guide groove 26 falls into the drop tube 36. Then the reset discharge tray 35 rotates and resets. As the rotating installation cylinder 28 driven by the driving member 3 46 rotates, the rotating coupling power supply of the rotating installation cylinder 28 is realized under the cooperation of the rotating conductive ring 50 and the rotating conductive groove 51, and the internal magnetic attraction coil part 62 generates a magnetic attraction force, so that a magnetic attraction force is generated near the cylinder wall of the rotating installation cylinder 28, and the inclined auxiliary magnetic attraction ring 52 is cooperated to magnetically adsorb the rare earth waste dropped in the drop tube 36. The offset guide protrusion 37 on the drop tube 36 makes the drop trajectory of the rare earth waste material offset toward the rotating installation cavity 56, thereby improving the effect of magnetic attraction. The magnetic material is captured and adsorbed on the inclined auxiliary magnetic attraction ring 52 by the magnetic attraction force, and moves with the rotation of the rotating installation cylinder 28. When it contacts the rotating scraper 54 and the upper inclined surface recess 55, the magnetic material on the inclined auxiliary magnetic attraction ring 52 is blocked. As more and more magnetic materials are blocked, the magnetic materials that exceed the magnetic attraction force fall into the collection conduit 47, and finally fall into the arc bottom storage cavity 34 through the collection conduit 47. After a period of time, the discharge gate 19 is opened to discharge the magnetic material collected in the arc bottom storage cavity 34 from the discharge hole 18. By driving the deflection column 53 to adjust the angle of the rotating scraper 54, the gap between the upper inclined surface notch 55 and the inclined surface auxiliary magnetic attraction ring 52 is adjusted to achieve the adjustment of the scraping efficiency of the magnetic material; The extracting liquid connected to the outside is introduced into the liquid storage chamber 38 through the connecting conduit 12, and the extracting liquid in the liquid storage chamber 38 is introduced into the mixing chamber 29 through the control of the valve body 40. The extracting liquid in the mixing chamber 29 is mixed with the rare earth waste after magnetic attraction treatment. As the rotating member 30 rotates, when one edge of the triangular prism structure of the rotating member 30 passes through the inner wall of the hyperbolic mounting cylinder 1 corresponding to the mixing chamber 29, it will definitely squeeze the triggering protrusion 60, so that the elastic layer 59 is deformed, and then the triggering protrusion moves into the trigger mounting chamber 57 and squeezes the passive lever 58, so that the rotating discharge plate 49 rotates around the rotating end. The shaft rotates to realize the opening of the rotating discharge plate 49 to connect the hyperbolic mounting cylinder 1 and the mixing chamber 29. At this time, part of the mixture of the extract and the rare earth waste enters the space formed by the convex arc surface of a rotating member 30 and the inner wall of the hyperbolic mounting cylinder 1. The capacity expansion chamber 31 is used to increase the volume of the space. With the further rotation of the rotating member 30, the rotating discharge plate 49 is reset under the action of the reset shaft, cutting off the connection between the hyperbolic mounting cylinder 1 and the mixing chamber 29, and the reset force causes the extract and rare earth waste in the mixing chamber 29 to impact the auxiliary mixing sheet 48, thereby improving the mixing effect of the extract and the rare earth waste.

[0040] Example 4, based on Example 1, please refer to Figure 1 to Figure 3 and Figure 5 In the embodiment of the present invention, a recovery and discharge mechanism is provided, and the recovery and discharge mechanism is provided at the lower side of another curved surface of the hyperbolic mounting cylinder 1. The recovery and discharge mechanism includes a collection mounting cylinder 7 provided at the outer side of another curved surface of the hyperbolic mounting cylinder 1. An expansion mounting cylinder 8 is provided at the bottom of the collection mounting cylinder 7. The cross section of the expansion mounting cylinder 8 is in the shape of a water drop. An upper discharge pipe 9 and a lower discharge pipe 10 are provided at both ends of the expansion mounting cylinder 8. The upper discharge pipe 9 and the lower discharge pipe 10 are connected to the expansion mounting cylinder 8 one above and one below. A diverter plate 42 is provided on the inner wall of the expansion mounting cylinder 8 on the upper side of the upper discharge pipe 9; A plurality of strip-shaped flow guide holes 41 are arranged at equal angles on the wall of the hyperbolic mounting cylinder 1 opposite to the aggregate mounting cylinder 7. The cross-section of the strip-shaped flow guide holes 41 is trapezoidal, and the flow guide area of ​​the strip-shaped flow guide holes 41 gradually decreases from the inside to the outside of the hyperbolic mounting cylinder 1.

[0041] Until the next edge of the triangular prism structure of the rotating member 30 passes through the inner wall of the hyperbolic mounting barrel 1 corresponding to the mixing chamber 29, the extracting liquid and the rare earth waste have entered the space formed by the convex arc surface of the rotating member 30 and the inner wall of the hyperbolic mounting barrel 1. As the rotating member 30 rotates, the volume shrinks and expands. During this process, the temperature and pressure of the mixture of the extracting liquid and the rare earth waste change at a high speed, which significantly improves the quality and efficiency of the extraction. The extracting liquid and the rare earth waste can be fully extracted in the process of the mixing chamber 29 moving to the collecting mounting barrel 7. When passing through the strip-shaped flow guide hole 41, the extract and rare earth waste therein are squeezed into the aggregate installation cylinder 7 through the strip-shaped flow guide hole 41, and then introduced into the diameter-expanding installation cylinder 8. Since the cross-section of the strip-shaped flow guide hole 41 is a trapezoid, the mixture of the extract and the rare earth waste is in a jet state when it is discharged, and hits the inner wall of the aggregate installation cylinder 7, further improving the quality of extraction; Finally, the waste is temporarily stored in the water drop-shaped structure of the enlarged diameter mounting tube 8 to complete the stratification, and the extracted liquid is discharged through the upper discharge pipe 9 after the extraction is completed. After a period of time, the deposited waste is extracted through the lower discharge pipe 10.
