[0002] Rare earth elements are mainly used in agriculture, metallurgy, petrochemicals, glass manufacturing, ceramics, and electric light source industries. With in-depth research into rare earth elements, their application in high-tech industries is gradually increasing. In the machinery sector, the utilization rate of rare earth elements is continuously increasing. However, the amount of rare earth waste generated during production is also growing. Furthermore, the over-exploitation of rare earth resources has not only resulted in significant resource waste but also caused serious environmental pollution. Therefore, increasing the recycling and utilization of rare earth materials has significant social, environmental, and economic benefits.

[0003] When recycling rare earth waste, it is generally necessary to crush the rare earth waste.

Detailed Implementation

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0022] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0023] like Figure 1 , Figure 2 , Figure 5 The diagram shows a structural representation of a rare earth waste recycling device for the mechanical field, provided by an embodiment of the present invention. The device includes a recycling box 1, with support legs 11 fixedly installed around the bottom wall of the recycling box 1. Feeding funnels 12 are provided on both sides of the recycling box 1. A guide outlet 13 is provided on the bottom wall of the recycling box 1, and a sealing plate 131 is rotatably installed inside the guide outlet 13. A locking element 8 that cooperates with the sealing plate 131 is provided on the bottom wall of the recycling box 1. A bearing column 2 is rotatably installed inside the recycling box 1, with one end extending to the outside of the recycling box 1. A screen plate 3 is fixedly installed on the surface of the bearing column 2, and the surface of the screen plate 3 has evenly distributed mesh. A crushing mechanism 4 is provided on the surface of the bearing column 2, the crushing mechanism 4 including… The recycling bin 1 has a squeezing roller 41 and a positioning component 42. The positioning component 42 is located on the surface of the support column 2 and is connected to the squeezing roller 41. The positioning component 42 is used to support and position the squeezing roller 41 above the support column 2. The side wall of the recycling bin 1 is provided with a control mechanism 5 that cooperates with the support column 2. The control mechanism 5 includes a swing component 51 and a flipping component 52. The swing component 51 is located on the side wall of the recycling bin 1 and is connected to the support column 2. The swing component 51 is used to control the support column 2 to reciprocate and rotate a certain angle in the inner cavity of the recycling bin 1. The flipping component 52 is connected to the swing component 51. The flipping component 52 controls the support column 2 and the screen plate 3 to rotate 180 degrees in the inner cavity of the recycling bin 1 by cooperating with the swing component 51.

[0024] Initially, the screening plate 3 is kept horizontal in the inner cavity of the recycling box 1. The positioning component 42 controls the squeezing roller 41 to be directly above the screening plate 3. The crushed rare earth waste that needs to be screened is fed into the inner cavity of the recycling box 1 through the feeding funnel 12. The rare earth waste falls onto the surface of the screening plate 3. The swing component 51 controls the bearing column 2 to rotate back and forth in the inner cavity of the recycling box 1. The bearing column 2 drives the screening plate 3 to rotate back and forth synchronously at a certain angle in the inner cavity of the recycling box 1. When the screening plate 3 swings back and forth, it can drive the rare earth waste on the surface of the screening plate 3 to roll synchronously. Particles of suitable size pass through the mesh on the surface of the screening plate 3 and fall to the bottom of the recycling box 1. At this time, the guide port 13 is in the open state. The waste particles screened at the bottom of the recycling box 1 pass through the guide port 13 and fall to the outside of the recycling box 1. The sieve plate 3 continues to swing, and larger rare earth particles fall onto its surface. After initial screening, the locking member 8 fixes the sealing plate 131 inside the guide port 13, which is now closed. The flipping component 52 and the swinging component 51 work together to control the support column 2 and the sieve plate 3 to rotate 180 degrees within the recycling box 1. At this point, larger rare earth particles on the surface of the sieve plate 3 fall to the bottom of the recycling box 1. The positioning component 42 then controls the squeezing roller 41 to be directly below the sieve plate 3. The swinging component 51 then controls the support column 2 and the sieve plate 3 to swing back and forth with small amplitudes. The positioning components 42 work together to control the extrusion roller 41 to roll back and forth at the bottom of the recycling box 1. The extrusion roller 41 can crush and pulverize the larger rare earth particles at the bottom of the recycling box 1. After crushing and pulverizing, the flipping component 52 and the swing component 51 work together to control the bearing column 2 and the screen plate 3 to rotate 180 degrees again. At this time, the extrusion roller 41 moves to the top of the screen plate 3 again. When the screen plate 3 rotates, it shovels the crushed rare earth particles at the bottom of the recycling box 1 back onto the surface of the screen plate 3. The swing component 51 controls the bearing column 3 and the screen plate 3 to swing back and forth, which can screen and filter the rare earth particles again.

[0025] like Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, in a preferred embodiment of the present invention, the positioning component 42 includes two sets of oppositely distributed side plates 421 fixedly mounted on the surface of the bearing column 2. The ends of the two sets of side plates 421 away from the bearing column 2 are rotatably mounted on a rotating column 422. The extrusion roller 41 is fixedly mounted on the surface of the rotating column 422. The surface of the side plate 421 is provided with a buffer part 6 connected to the rotating column 422. The buffer part 6 is used to adjust the relative position of the rotating column 422 and the side plate 421.

[0026] Two sets of side plates 421 support and position the rotating column 422 and the extrusion roller 41. Initially, the extrusion roller 41 is above the screen plate 3. When the supporting column 2 swings back and forth, the extrusion roller 41 rotates synchronously above the screen plate 3. The extrusion roller 41 does not interfere with the screening process of rare earth particles. When it is necessary to crush the larger rare earth particles left on the surface of the screen plate 3, the locking member 8 fixes the position of the sealing plate 131 in the guide port 13. At this time, the guide port 13 is in a closed state. The flipping component 52 and the swinging component 51 cooperate to control the supporting column 2 and the screen plate 3 to rotate 180 degrees. At this time, the extrusion roller 41 moves to the bottom of the screen plate 3 and is located at the bottom of the recycling box 1. When the swinging component 51 controls the supporting column 2 to rotate back and forth, the side plates 421 and the rotating column 422 cooperate to drive the extrusion roller 41 to roll back and forth at the bottom of the recycling box 1. The extrusion roller 41 can crush the larger rare earth particles.

[0027] like Figure 5 , Figure 6 As shown, in a preferred embodiment of the present invention, the buffer part 6 includes two sets of sliding grooves 61 respectively opened on the surface of the side plates 421. A bearing block 62 is slidably installed in the sliding groove 61. The two ends of the rotating column 522 are respectively rotatably connected to the bearing block 62. A compression spring 63 is fixedly installed at one end of the sliding groove 61 near the bearing column 2. The extension end of the compression spring 63 is connected to the bearing block 62.

[0028] When the side plate 421 drives the rotating column 422 and the squeezing roller 41 to roll at the bottom of the recycling box 1, the squeezing spring 63 applies a pushing force to the bearing block 62, which in turn applies pressure to the squeezing roller 41 toward the bottom wall of the recycling box 1. The bearing block 62 moves in the slide 61, which can adjust the position of the squeezing roller 41 and prevent the rare earth particles from getting stuck in the gap between the squeezing roller 41 and the recycling box 1 when the size is large.

[0029] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, in a preferred embodiment of the present invention, the swing assembly 51 includes a positioning plate 511 fixedly installed at one end of the bearing column 2 located outside the recycling bin 1. The positioning plate 511 has an elongated guide groove 512 on its surface. A drive disk 513 is rotatably installed on the side wall of the recycling bin 1. A guide post 514 is provided on the surface of the drive disk 513 at a position off-center. The guide post 514 is inserted into the guide groove 512. A motor 515 is fixedly installed on the side wall of the recycling bin 1 by a bracket. A transmission gear disk 516 is fixedly installed on the output shaft of the motor 515. A gear ring 517 that meshes with the transmission gear disk 516 is fixedly installed on the annular side wall of the drive disk 513.

[0030] In use, the motor 515 drives the transmission gear plate 516 to rotate. The transmission gear plate 516 meshes with the gear ring 517, which can drive the drive plate 513 to rotate. The drive plate 513 drives the guide column 514 to rotate synchronously. When the guide column 514 rotates, it cooperates with the guide groove 512, which can drive the positioning plate 511 to swing back and forth at a certain angle. When the positioning plate 511 swings, it drives the bearing column 2 and the screen plate 3 to rotate synchronously back and forth in the inner cavity of the recycling box 1.

[0031] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, in a preferred embodiment of the present invention, the flipping assembly 52 includes a toothed ring 522 sleeved on the surface of the bearing column 2. The toothed ring 522 meshes with a toothed ring 517. A telescopic cavity 523 is provided inside the bearing column 2. A first electric telescopic rod 524 is fixedly installed in the telescopic cavity 523. A sliding block 525 is fixedly installed at the telescopic end of the first electric telescopic rod 524. Multiple sets of connecting rods 526 are fixedly installed on the side wall of the sliding block 525. One end of the connecting rod 526 away from the sliding block 525 extends to the outside of the bearing column 2 and is fixedly connected to the toothed ring 522. A storage cavity 527 is provided inside the drive disk 513. A second electric telescopic rod 528 is fixedly installed in the storage cavity 527. The telescopic end of the second electric telescopic rod 528 is connected to the guide column 514. Two sets of positioning plates 511 are provided and are distributed opposite to each other on the surface of the bearing column 2.

[0032] Initially, the toothed ring 522 and the toothed ring 517 are separated. When it is necessary to further crush the larger rare earth particles on the surface of the screen plate 3, the second electric telescopic rod 528 controls the guide column 514 to move into the receiving cavity 527. At this time, the guide column 514 moves to the outside of the guide groove 512, and the first electric telescopic rod 524 pulls the sliding block 525 to move in the telescopic cavity 523, thereby driving the toothed ring 522 to move synchronously outside the bearing column 2. After the toothed ring 522 and the toothed ring 517 are engaged, the motor 515 drives the transmission gear plate 516 to rotate, and the transmission gear plate 516 and the toothed ring 517... The meshing transmission drives the drive disc 513 to rotate. The meshing transmission between the gear ring 517 and the gear ring 522 drives the bearing column 2 to rotate synchronously. After the bearing column 2 and the screen plate 3 have rotated 180 degrees inside the recycling box 1, the motor 515 stops rotating. The first electric telescopic rod 524 pushes the sliding block 525 to move within the telescopic cavity 523, thereby causing the gear ring 522 and the gear ring 517 to separate. The second electric telescopic rod 528 pushes the guide column 514 to move outward toward the outside of the receiving cavity 527, so that the guide column 514 is inserted into the guide groove 512 on the surface of another set of positioning plates 511. The motor 515 drives the transmission gear disc 516 to rotate. The transmission gear disc 516 meshes with the gear ring 517, which drives the drive disc 513 to rotate. The drive disc 513 drives the guide column 514 to rotate synchronously. When the guide column 514 rotates, it cooperates with the guide groove 512, which can drive the positioning plate 511 to swing back and forth again.

[0033] like Figure 2 , Figure 5 As shown, in a preferred embodiment of the present invention, the two ends of the screening plate 3 are respectively provided with guide plates 7, and the guide plates 7 are attached to the inner side wall of the recycling box 1.

[0034] The guide plate 7 can effectively prevent rare earth particles from getting stuck in the gap between the screen plate 3 and the inner wall of the recycling box 1.

[0035] like Figure 1 , Figure 2 As shown, in a preferred embodiment of the present invention, the locking member 8 includes a base plate 81 fixedly installed on the bottom wall of the sealing plate 131, the surface of the recycling bin 1 is provided with a threaded hole 82, and the surface of the base plate 81 is provided with a fixing bolt 83 that cooperates with the threaded hole 82.

[0036] By using the fixing bolt 83 and the threaded hole 82 to cooperate with each other, the position of the base plate 81 and the sealing plate 131 can be easily adjusted. During screening, the guide port 13 is in an open state, and when crushing is required, the sealing plate 131 controls the guide port 13 to be in a closed state.

[0037] The working principle of this invention is as follows: Initially, the screening plate 3 is kept horizontal in the inner cavity of the recycling box 1, and the extrusion roller 41 is above the screening plate 3. The rare earth waste that needs to be screened after crushing is fed into the inner cavity of the recycling box 1 through the feeding funnel 12, and the rare earth waste falls onto the surface of the screening plate 3.

[0038] Motor 515 drives transmission gear 516 to rotate. Transmission gear 516 meshes with gear ring 517, which drives drive disc 513 to rotate. Drive disc 513 drives guide column 514 to rotate synchronously. When rotating, guide column 514 cooperates with guide groove 512, which drives positioning plate 511 to swing back and forth at a certain angle. When positioning plate 511 swings, it drives bearing column 2 and screen plate 3 to rotate synchronously back and forth in the inner cavity of recycling box 1. When screen plate 3 swings back and forth, it can drive the rare earth waste on the surface of screen plate 3 to roll synchronously. Particles of suitable size pass through the mesh on the surface of screen plate 3 and fall to the bottom of recycling box 1. At this time, guide port 13 is in the open state. The waste particles screened at the bottom of recycling box 1 pass through guide port 13 and fall to the outside of recycling box 1. The sieve plate 3 continuously oscillates, and larger rare earth particles fall onto its surface. After initial screening, and when it is necessary to crush the larger rare earth particles remaining on the sieve plate 3, the positions of the base plate 81 and the sealing plate 131 are adjusted by the cooperation of the fixing bolt 83 and the threaded hole 82. The sealing plate 131 controls the guide port 13 to be in a closed state. The second electric telescopic rod 528 controls the guide column 514 to move into the receiving cavity 527. At this time, the guide column 514 moves to the outside of the guide groove 512. The first electric telescopic rod 524 pulls the sliding block 525 to move in the telescopic cavity 523, thereby driving the toothed ring 522 to move synchronously outside the bearing column 2. After the toothed ring 522 meshes with the toothed ring 517, the motor 515 drives the transmission toothed disc 516 to rotate. The transmission toothed disc 516 meshes with the toothed ring 517, which can drive the drive disc 513 to rotate. The gear ring 522 engages in transmission, driving the bearing column 2 to rotate synchronously. After the bearing column 2 and the screen plate 3 have rotated 180 degrees inside the recycling box 1, the motor 515 stops rotating. The first electric telescopic rod 524 pushes the sliding block 525 to move within the telescopic cavity 523, thereby separating the gear ring 522 from the gear ring 517. The second electric telescopic rod 528 pushes the guide column 514 to move outward from the receiving cavity 527, causing the guide column 514 to insert into the guide groove 512 on the surface of another set of positioning plates 511. The motor 515 drives the transmission gear disc 516 to rotate. The transmission gear disc 516 engages in transmission with the gear ring 517, driving the drive disc 513 to rotate. The drive disc 513 drives the guide column 514 to rotate synchronously. When rotating, the guide column 514 cooperates with the guide groove 512, causing the positioning plate 511 to swing back and forth again. The positioning plate 511 drives the bearing column 2 to rotate back and forth. The side plate 421 and the rotating column 422 cooperate with each other to drive the extrusion roller 41 to roll back and forth at the bottom of the recycling box 1. The extrusion roller 41 can crush and pulverize large rare earth particles.After crushing, the bearing column 2 and the screen plate 3 can be controlled to rotate 180 degrees again. At this time, the extrusion roller 41 moves to the top of the screen plate 3 again. When the screen plate 3 rotates, it shovels the crushed rare earth particles from the bottom of the recycling box 1 back onto the surface of the screen plate 3. By controlling the bearing column 3 and the screen plate 3 to swing back and forth, the rare earth particles can be screened and filtered again.

[0039] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
