Description

Technical Field

[0001] This invention belongs to the field of waste recycling, specifically relating to a high-purity rare earth metal waste recycling device. Background Technology

[0002] Existing high-purity rare earth metal waste recycling devices mostly adopt a fixed feeding method, which makes it easy for waste to accumulate locally on the sorting plate, resulting in uneven sorting, mixing of large pieces and fine chips. Moreover, relying solely on the shaking of the sorting plate cannot achieve uniform spreading of waste. Fine chips are easily wrapped by large pieces, and impurities are difficult to separate, making subsequent purification and impurity removal difficult. This affects the purity and yield of recycled rare earth metals and makes it difficult to meet the stable and efficient requirements of high-purity recycling.

[0003] Patent CN116219209B discloses a praseodymium-neodymium metal waste recycling and processing device, including a base, a support frame fixedly connected to the base, and a processing shell fixedly connected to the support frame. This patent provides a praseodymium-neodymium metal waste recycling and processing device that uses a motor to drive a rotating plate within a circular frame. The rotating plate causes two main magnetic blocks to intermittently overlap with two auxiliary magnetic blocks, causing the hopper shell to shake continuously, thus shaking out dust from the metal waste. Simultaneously, a fan is activated, causing airflow to carry the dust into the collection box, automatically completing the recycling and processing of the metal waste. The cleaning of waste materials involves activating a hydraulic cylinder to move a rack plate, which in turn drives a gear to rotate, causing the bucket to rotate and automatically dump the cleaned metal scraps into a collection bin. However, during the process of dumping the waste, it is difficult to distribute the waste evenly onto the sorting plate. Furthermore, after dumping, it is difficult to make the sorting plate vibrate to improve the sorting and recycling speed. This can lead to a slower recovery and rare earth metal extraction rate, affecting the efficiency of subsequent recovery and rare earth metal extraction. Summary of the Invention

[0004] The purpose of this invention is to provide a high-purity rare earth metal waste recycling device to solve the problem of inaccurate recycling and sorting.

A leveling mechanism for spreading the waste is disposed on the inner wall of the sorting box, and a collection mechanism for collecting and recycling is disposed on the inner wall of the fine material box. A reciprocating screw is rotatably connected to the inner wall of the sorting box, and a moving rod is movably connected to the circumferential surface of the reciprocating screw. A limit post is fixedly connected to the inner wall of the sorting box, and a guide box is fixedly connected to the front of the moving rod.

[0009] In one or more embodiments of the present invention, the smoothing mechanism further includes a limiting slide bar, the limiting slide bar being fixedly connected to the inner wall of the sorting box, a fixed groove bar being fixedly connected to the bottom of the guide box, a connecting rod being fixedly connected to the inner wall of the fixed groove bar, a fixed column being slidably connected to the inner wall of the limiting slide bar, and an elastic telescopic rod being fixedly connected to the bottom of the fixed column.

The inclined push plate can flatten the waste material remaining on the surface of the sorting filter plate and simultaneously push the waste material to move, ensuring that a certain number of smaller waste materials remain on the surface of the sorting filter plate. This improves the recovery efficiency of the device, completely eliminates local accumulation, makes the sorting filter plate cleaner, reduces entrained mixed materials, lowers the difficulty of purification and impurity removal, stabilizes the feeding rhythm, and ensures continuous and stable subsequent processes.

The guide plate and the dredging column can continuously push and move the waste in the guide box, which can prevent the waste in the guide box from clogging and affecting the subsequent sorting efficiency, and can directly improve the rare earth metal acquisition speed of the device.

[0013] In one or more embodiments of the present invention, the fine filter plate is located directly below the sorting box, the second fixed column is in contact with the guide box, the guide hinge plate is in contact with the guide box, the guide plate is in contact with the guide box, the movement of the connecting frame will drive the fixed frame to move, at this time the fixed frame can synchronously drive the second fixed column to move, and the movement of the second fixed column will drive the guide plate to move.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This high-purity rare earth metal waste recycling device, through the coordinated movement of its base, fine material box, sorting box, motor, leveling mechanism, collecting mechanism, reciprocating screw, moving rod, limiting column, guide box, first pulley, rotating column, second pulley, belt, sorting filter plate, fixed block, first roller, first elastic telescopic rod, and protruding rod, can ensure that the waste falls relatively evenly onto the surface of the sorting filter plate. This avoids local accumulation of waste, ensures thorough screening by the sorting filter plate, improves subsequent recycling accuracy, reduces mixing and impurity entrainment, lowers recycling difficulty, achieves a stable feeding rhythm, ensures continuous and stable recycling, and accelerates the speed at which the device obtains rare earth metals. It can also cause the waste on the surface of the sorting filter plate to shake, so that larger waste remains on the surface of the sorting filter plate, while smaller waste falls through the opening of the sorting filter plate. It can sort the waste according to its shape and size, avoid mixing and contamination, perform preliminary impurity removal, reduce the burden of subsequent purification, and improve the efficiency of subsequent recycling and purification, as well as the purity and yield of the final rare earth metal.

[0015] 2. This high-purity rare earth metal waste recycling device utilizes the coordinated movement of guide blocks, elastic telescopic rod II, connecting frame, roller II, moving frame, sealing plate, limiting slide rod, fixed groove rod, connecting rod, fixed column I, elastic telescopic rod III, and inclined push plate. This allows the sealing plate to open the bottom opening of the guide box, enabling waste to fall in during the guide box's movement. This effectively prevents waste accumulation, which would otherwise affect subsequent sorting and recycling efficiency, thus improving the quality of the obtained rare earth metals. The inclined push plate flattens the waste remaining on the surface of the sorting filter plate and pushes it forward, ensuring that some smaller pieces of waste remain on the filter plate surface. This improves the device's recycling efficiency, completely eliminates localized accumulation, ensures cleaner sieving, reduces entrainment and mixing, lowers the difficulty of purification and impurity removal, stabilizes the feeding rhythm, and guarantees continuous and stable subsequent processes.

At this time, the operator can quickly collect and recycle the waste. The structure is simple and can collect and recycle quickly, which can improve the recycling efficiency of the device and thus improve the rare earth metal acquisition efficiency. The guide plate and unblocking column can continuously push and move the waste in the guide box, which can prevent the waste in the guide box from clogging and affecting the subsequent sorting efficiency, and can directly improve the rare earth metal acquisition speed of the device.

[0019] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figures 1-9 As shown, a high-purity rare earth metal waste recycling device includes a base 1 and a belt 14. A fine material box 2 is provided on the top of the base 1, and a sorting box 3 is installed on the fine material box 2. A motor 4 is installed on the sorting box 3. A smoothing mechanism 5 for spreading the waste is provided on the inner wall of the sorting box 3, and a collection mechanism 6 for collecting and recycling is provided on the inner wall of the fine material box 2. A reciprocating screw 7 is rotatably connected to the inner wall of the sorting box 3, and a moving rod 8 is movably connected to the circumferential surface of the reciprocating screw 7. A limit post 9 is fixedly connected to the inner wall of the sorting box 3, and the moving rod 8... A guide box 10 is fixedly connected to the front. A first leather wheel 11 is fixedly connected to the circumferential surface of the reciprocating screw 7. A rotating column 12 is rotatably connected to the inner wall of the sorting box 3. A second leather wheel 13 is fixedly connected to the circumferential surface of the rotating column 12. An elastic telescopic rod 18 is fixedly connected to the inner wall of the sorting box 3. A sorting filter plate 15 is fixedly connected to the telescopic end of the elastic telescopic rod 18. A fixing block 16 is fixedly connected to the bottom of the sorting filter plate 15. A first roller 17 is rotatably connected to the inner wall of the fixing block 16. A protruding rod 19 is fixedly connected to the circumferential surface of the rotating column 12. When the device is ready for use, the operator first needs to discharge the high-purity rare earth metal waste into the guide box 10. After the preparation is completed, the motor 4 will start, and the motor 4 will drive the reciprocating screw 7 to rotate. During the rotation of the reciprocating screw 7, the rotation of the reciprocating screw 7 will drive the moving rod 8 to rotate. However, at this time, the moving rod 8 is limited by the movement guide of the limiting post 9. At this time, the limiting post 9 will cause the moving rod 8 to move laterally back and forth through the reciprocating groove opened on the surface of the limiting post 9 during the rotation of the reciprocating screw 7. During the movement, the movement of the moving rod 8 will synchronously drive the guide box 10 to move. During the movement of the guide box 10, the metal waste in the guide box 10 can fall into the sorting box 3 through the opening at the bottom of the guide box 10. It can fall more evenly on the surface of the sorting filter plate 15, which can avoid local accumulation of waste, ensure that the sorting filter plate 15 can fully screen, improve the subsequent recycling accuracy, reduce mixing and impurity entrainment, reduce recycling difficulty, achieve a stable feeding rhythm, ensure continuous and stable recycling, and accelerate the speed at which the device obtains rare earth metals. The reciprocating screw 7 is fixedly connected to the output end of the motor 4. The moving rod 8 is slidably connected to the circumferential surface of the limiting post 9, and the limiting post 9 is used to guide and limit the movement of the moving rod 8. The first pulley 11 is connected to the belt 14 for transmission, and the belt 14 is connected to the second pulley 13 for transmission. The sorting filter plate 15 is slidably connected to the inner wall of the sorting box 3. The first roller 17 is located on the movement trajectory of the protruding rod 19, and the protruding rod 19 is used to push the first roller 17 to move upward. When the device is in use, the reciprocating screw 7 rotates, which in turn drives the first pulley 11 to rotate. The first pulley 11, in turn, drives the second pulley 13 to rotate via the belt 14. The second pulley 13, in turn, drives the rotating column 12 to rotate. The rotating column 12, in turn, drives the protruding rod 19 to rotate. During its rotation, the protruding rod 19 contacts the first roller 17 and, through its curved surface, pushes the first roller 17 upwards. The upward movement of the first roller 17 causes the fixed block 16 to move. The movement will cause the sorting filter plate 15 to move upward. When the protruding rod 19 is no longer in contact with the roller 17, the elastic telescopic rod 18 can drive the sorting filter plate 15 to reset downward through its own reset characteristics. During this process, the up and down movement of the sorting filter plate 15 can cause it to shake, which can cause the waste on the surface of the sorting filter plate 15 to shake. Larger waste will stay on the surface of the sorting filter plate 15, while smaller waste will fall through the opening of the sorting filter plate 15. The waste can be sorted according to its shape and size, avoiding mixed material contamination, initially removing impurities, reducing the burden of subsequent purification, and improving the efficiency of subsequent recycling and purification and the purity and yield of the final rare earth metal. Overall working principle: The waste material can fall relatively evenly onto the surface of the sorting filter plate 15, avoiding local accumulation and ensuring that the sorting filter plate 15 can fully screen the waste, improving the subsequent recycling accuracy, reducing mixing and impurity entrainment, reducing recycling difficulty, achieving a stable feeding rhythm, ensuring continuous and stable recycling, and accelerating the acquisition of rare earth metals by the device. It can also cause the waste material on the surface of the sorting filter plate 15 to shake, so that larger waste materials remain on the surface of the sorting filter plate 15, while smaller waste materials will fall through the opening of the sorting filter plate 15. It can sort the waste materials according to their shape and size, avoid mixing and contamination, perform preliminary impurity removal, reduce the burden of subsequent purification, and improve the efficiency of subsequent recycling and purification and the final purity and yield of rare earth metals.

[0021] Please see Figure 1-9 Figure 1 shows that, based on the above embodiments, in another embodiment of the present invention, the smoothing mechanism 5 includes a guide block 501, the guide block 501 is fixedly connected to the inner wall of the sorting box 3, the front part of the guide box 10 is fixedly connected to an elastic telescopic rod 502, the telescopic end of the elastic telescopic rod 502 is fixedly connected to a connecting frame 503, the inner wall of the connecting frame 503 is rotatably connected to a roller 504, the circumferential surface of the connecting frame 503 is fixedly connected to a movable frame 505, and the inner wall of the movable frame 505 is fixedly connected to a sealing plate 506. When the device is in use, the movement of the guide box 10 will cause the elastic telescopic rod 502 to move, which in turn will cause the connecting frame 503 to move. During the movement of the connecting frame 503, the connecting frame 503 will drive the roller 504 to move. After moving a certain distance, the roller 504 will no longer be in contact with the guide block 501. At this time, the elastic telescopic rod 502 will return to its original position, and the movement of the elastic telescopic rod 502 will drive the roller 504 to move. The movement will cause the connecting frame 503 to move, and the movement of the connecting frame 503 will cause the moving frame 505 to move. During the movement of the moving frame 505, the moving frame 505 will cause the sealing plate 506 to move. After the sealing plate 506 moves a certain distance, the sealing plate 506 can open the opening at the bottom of the guide box 10. At this time, the waste can be dropped into the guide box 10 during the movement, which can effectively prevent the accumulation of waste and thus affect the subsequent sorting and recycling efficiency, and improve the quality of rare earth metals obtained. The smoothing mechanism 5 also includes a limiting slide bar 507, which is fixedly connected to the inner wall of the sorting box 3. A fixed groove bar 508 is fixedly connected to the bottom of the guide box 10. A connecting rod 509 is fixedly connected to the inner wall of the fixed groove bar 508. A first fixed column 510 is slidably connected to the inner wall of the limiting slide bar 507. An elastic telescopic rod 511 is fixedly connected to the bottom of the first fixed column 510. An inclined push plate 512 is fixedly connected to the telescopic end of the elastic telescopic rod 511. A second roller 504 contacts the guide block 501. A connecting frame 503 contacts the guide box 10. A sealing plate 506 contacts the guide box 10 and seals the opening of the guide box 10. An inclined push plate 512 contacts the sorting box 3. A connecting rod 509 is fixedly connected to the circumferential surface of the first fixed column 510. When the device is in use, the movement of the guide box 10 will cause the fixed groove rod 508 to move, which in turn will cause the connecting rod 509 to move. During the movement of the connecting rod 509, the connecting rod 509 will simultaneously cause the fixed column 510 to move. At this time, the fixed column 510 will move stably on the inner wall of the limiting slide bar 507. The movement of the fixed column 510 will cause the elastic telescopic rod 511 to move, which in turn will cause the inclined push plate 512 to move. When the inclined push plate 512 is no longer in contact with the sorting box 3, the elastic... The telescopic rod 511 will drive the inclined push plate 512 to move downward through its own reset characteristics. At this time, during the movement, the inclined push plate 512 can flatten the waste material remaining on the surface of the sorting filter plate 15 and push the waste material to move, so that a certain amount of smaller waste material remains on the surface of the sorting filter plate 15. This can improve the recovery efficiency of the device, completely eliminate local accumulation, make the sorting filter plate 15 screen cleaner, reduce the entrainment of mixed materials, reduce the difficulty of purification and impurity removal, stabilize the feeding rhythm, and ensure the continuous and stable operation of subsequent processes. This is an important guarantee for obtaining qualified high-purity rare earth metals. The collection mechanism 6 includes a sliding door 601, which is slidably connected to the inner wall of the fine material box 2. A recycling box 602 is installed on the inner wall of the fine material box 2, and a fine filter plate 603 is fixedly connected to the inner wall of the recycling box 602. When the device is in use, after being sorted by the sorting filter plate 15, the smaller waste materials can fall into the recycling box 602 inside the fine material box 2. At the same time, the fine filter plate 603 inside the recycling box 602 can screen the waste materials again, allowing the waste materials in the recycling box 602 to be separated again. Meanwhile, the operator can pull the sliding door 601 to open the fine material box 2, at which time the operator can quickly collect and recycle the waste materials. The structure is simple and can collect and recycle quickly, which can improve the recycling efficiency of the device and thus improve the efficiency of rare earth metal acquisition. The collection mechanism 6 also includes a fixing frame 604, which is fixedly connected to the circumferential surface of the connecting frame 503. The inner wall of the fixing frame 604 is fixedly connected to a second fixing column 605. The circumferential surface of the second fixing column 605 is fixedly connected to a guide plate 606. The circumferential surface of the guide plate 606 is rotatably connected to a guide hinge plate 608 via a torsion spring. The rear part of the guide plate 606 is fixedly connected to a clearing column 607. The fine filter plate 603 is located directly below the sorting box 3. The second fixing column 605 is in contact with the guide box 10, the guide hinge plate 608 is in contact with the guide box 10, and the guide plate 606 is in contact with the guide box 10. When the device is in use, the connecting frame 503 moves back and forth, and the movement of the connecting frame 503 will drive the fixed frame 604 to move. At this time, the fixed frame 604 can synchronously drive the fixed column 605 to move. The movement of the fixed column 605 will drive the guide plate 606 to move. The movement of the guide plate 606 will drive the unblocking column 607 to move. During the movement of the unblocking column 607 and the guide plate 606, the guide plate 606 and the unblocking column 607 can continuously push and move the waste in the guide box 10, which can prevent the waste in the guide box 10 from clogging and affecting the subsequent sorting efficiency, and can directly improve the rare earth metal acquisition speed of the device. Overall working principle: The sealing plate 506 opens the bottom opening of the guide box 10, allowing waste to fall in during the movement of the guide box 10. This effectively prevents waste accumulation, which would affect the subsequent sorting and recycling efficiency and improve the quality of rare earth metals obtained. The inclined push plate 512 flattens the waste remaining on the surface of the sorting filter plate 15 and pushes the waste to move, ensuring that some smaller pieces of waste remain on the surface of the sorting filter plate 15. This improves the recycling efficiency of the device, completely eliminates local accumulation, makes the sorting filter plate 15 screen cleaner, reduces entrained mixed materials, lowers the difficulty of purification and impurity removal, stabilizes the feeding rhythm, and ensures the continuity of subsequent processes. Continuous stability is a crucial guarantee for obtaining qualified high-purity rare earth metals. Operators can pull the sliding door 601 to open the fine material box 2, allowing for quick collection and recycling of waste. The simple structure and rapid collection and recycling capabilities improve the device's recycling efficiency, thereby increasing the efficiency of rare earth metal acquisition. The movement of the guide plate 606 moves the unblocking column 607. During this movement, the guide plate 606 and the unblocking column 607 continuously push and move the waste in the guide box 10, preventing blockage and ensuring efficient subsequent sorting. This directly improves the rare earth metal acquisition speed of the device.
