Description

Technical Field

[0001] The invention belongs to the technical field of SmFeN magnetic steel cleaning, and in particular relates to a SmFeN magnetic steel cleaning device and a cleaning method. Background Art

[0002] SmFeN magnet is a new type of high-performance permanent magnet material. SmFeN magnet was first developed and studied in the 1990s. It was created to overcome the problem of magnetic property degradation of early rare earth permanent magnet materials (such as NdFeB magnet) at high temperatures. With the deepening of research, the manufacturing process and performance of SmFeN magnet have been continuously improved. It has been applied in some specific fields. With the advancement of research and technology, the production cost of SmFeN magnet may be reduced, and its application range is expected to be further expanded. Against the background of growing demand for high-performance magnetic materials, SmFeN magnet has great market potential. Overall, SmFeN magnet is a new type of permanent magnet material with superior magnetic properties. Although it faces some technical and cost challenges, its unique properties make it important in high-performance magnetic applications.

[0003] There are many pollutants and impurities attached to the surface of SmFeN magnets, which need to be cleaned during the application process to avoid the negative impact of these impurities on the performance of the magnets. During the operation of the existing SmFeN magnet cleaning equipment, due to the strong magnetism of the SmFeN magnets themselves, the SmFeN magnets adsorb each other and cannot be fully cleaned. In addition, cleaning fluid will remain on the surface of the SmFeN magnets after cleaning. Long-term residue will cause corrosion on the surface of the SmFeN magnets, thereby affecting the magnetic properties of the magnets, including the magnetic field strength and stability, resulting in the performance of the magnets failing to meet expectations. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a samarium iron nitrogen magnetic steel cleaning device and a cleaning method.

[0005] The technical solution adopted to solve the above technical problems is: a samarium iron nitrogen magnetic steel cleaning device, comprising a cleaning pool, a bracket is fixedly connected to the bottom of the cleaning pool, and a magnetic steel inlet is opened on the top of the cleaning pool; A swing mechanism is installed inside the cleaning pool, a fixing mechanism is installed on one side of the swing mechanism, and a lifting mechanism is installed inside the fixing mechanism.

[0006] Furthermore, the swing mechanism includes a first motor fixedly connected to one side of the cleaning tank, a rotating shaft is rotatably connected inside both sides of the cleaning tank, the outer walls of the two rotating shafts are fixedly connected to rockers, the other ends of the two rockers are rotatably connected to rings, the inner walls of the two rings are slidably connected to cylinders, the upper and lower ends of the two cylinders are fixedly connected to connecting rods, the middle ends of the multiple connecting rods are rotatably connected to pillars, the other ends of the multiple connecting rods are rotatably connected to the first connecting seat, the outer walls of the two pillars are fixedly connected to fixed plates, the other end of one of the rotating shafts is fixedly connected to the first motor, the upper and lower ends of one of the pillars are fixedly connected to the cleaning tank, the bottom of the other cleaning tank is fixedly connected to the cleaning tank, and the front and rear ends of the two fixed plates are fixedly connected to the cleaning tank.

[0007] Through the above technical scheme, when in use, after the SmFeN magnet is placed in the cleaning equipment, it can be swung by the swing mechanism so that the SmFeN magnet can be completely in contact with the cleaning liquid. The flow of the cleaning liquid can be increased by shaking, so that the SmFeN magnet can be completely rinsed. For magnets with complex shapes, shaking can help the cleaning agent penetrate into hard-to-reach areas. In addition, swinging can keep the cleaned magnets evenly distributed on the mesh plate to avoid stacking or mutual adsorption, which is convenient for subsequent operations. Specifically, the first motor on one side of the cleaning tank is started to drive the rocker on the outer wall of one of the rotating shafts to rotate. At this time, the rocker makes a circular motion, so that the ring can slide up and down on the cylinder. With the support of the pillar, the two connecting rods can swing on both sides, thereby driving the cleaning screen frame of the first connecting seat at the other end of the two connecting rods to move and shake. At this time, the swing of the cleaning screen frame can increase the internal flow of the cleaning liquid, and can better clean the samarium iron nitrogen magnetic steel. At the same time, the other side of the cleaning screen frame is performing the same swing. On the one hand, the swinging of the two ends can better support the cleaning screen frame. On the other hand, the pillar is used as a support to complete a moving and shaking process. In the case of swinging, the spring between the first fixed seat on the front and rear end surfaces of the cleaning screen frame and the second fixed seat fixed on the inner wall of the front and rear end of the cleaning tank will stretch and extend, so that the samarium iron nitrogen magnetic steel can be better laid flat inside.

[0008] Furthermore, the fixing mechanism includes a cleaning net frame fixedly connected to one side of a plurality of first connecting seats, two first fixing seats are fixedly connected to the front and rear end surfaces of the cleaning net frame, springs are fixedly connected inside the plurality of first fixing seats, the other ends of the plurality of springs are fixedly connected to a second fixing seat, and one ends of the plurality of second fixing seats are respectively fixedly connected to the inner walls of the front and rear ends of the cleaning pool.

[0009] Through the above technical solution, during the shaking of the samarium iron nitrogen magnet, the fixing mechanism can bind it, so that the cleaning screen frame can be more stable during the movement, and at the same time can better produce vibration during the shaking process to maintain a certain cleaning effect. Specifically, when the cleaning screen frame is shaking, the springs fixed by the first fixed seat on the front and rear sides of the cleaning screen frame are connected to the second fixed seat, so that the cleaning screen frame can slide within a certain range of the cleaning pool, avoiding collision between the cleaning pool and the cleaning screen frame, and reducing the safety hazards of the cleaning equipment.

[0010] Furthermore, the lifting mechanism includes a second motor fixedly connected to one side of the cleaning screen frame, the output end of the second motor is fixedly connected to the second driving shaft, the outer wall of the second driving shaft is fixedly connected to the first threaded rod, the outer wall of the second driving shaft is fixedly connected to the second threaded rod, the outer wall of the second driving shaft is fixedly connected to the third threaded rod, the outer walls of the second threaded rod and the third threaded rod are both rotatably connected to moving blocks, the inner wall of the moving block is provided with a wide thread, the inner wall of the moving block is provided with a narrow thread, the front and rear ends of the two moving blocks are rotatably connected to pull rods, the other ends of multiple pull rods are rotatably connected to second connecting seats, the bottoms of multiple second connecting seats are fixedly connected to bottom screen plates, the wide threaded outer wall is rotatably connected to the third threaded rod, the narrow threaded outer wall is rotatably connected to the second threaded rod, and the outer wall of the bottom screen plate is slidably connected to the cleaning screen frame.

[0011] By means of the above technical scheme, before the samarium iron nitrogen magnet is placed into the cleaning equipment, it is necessary to use a lifting mechanism to place it smoothly, so as to avoid collision between the cleaning liquid and the samarium iron nitrogen magnet and waste of the cleaning liquid. At the same time, the lifting mechanism can be tilted during the placement process, so that the samarium iron nitrogen magnet can slide according to the slope and its own gravity. The tilting can reduce the contact area between the magnets, reduce the attraction between them, prevent mutual adsorption or stacking, and facilitate cleaning and processing. At the same time, after cleaning, it can be tilted to the other side, so that the samarium iron nitrogen magnet can be stacked, which is more convenient for operators to collect and makes the cleaning and picking process more efficient. In addition, after cleaning is completed, it can cooperate with the swing mechanism to swing the cleaning liquid remaining on the surface of the samarium iron nitrogen magnet to reduce the residue on the surface of the samarium iron nitrogen magnet. Specifically, after the samarium iron nitrogen magnet is placed on the bottom mesh plate, the second motor on one side of the cleaning mesh frame can be started to drive the first threaded rod, the second threaded rod and the outer wall of the second drive shaft The third threaded rod rotates, and the thread groove on the outer wall of the third threaded rod is set to one section, the thread groove on the outer wall of the second threaded rod is set to three sections, and the thread groove on the outer wall of the first threaded rod is set to four sections, and the length of the third threaded rod is equal to that of the second threaded rod, and the length of the third threaded rod and the second threaded rod is equal to that of the first threaded rod. In addition, the narrow thread of the wide thread arranged on the inner wall of the moving block rotates with the corresponding third threaded rod and the second threaded rod respectively, and the built-in thread of another moving block rotates with the first threaded rod to ensure the meshing performance of the rotation. At the same speed, the moving distances of the two moving blocks will be different, which will drive the bottom mesh plate connected to the bottom of the second connecting seat corresponding to different pull rods to tilt, so that the samarium iron nitrogen magnetic steel can slide. Similarly, when rising, the samarium iron nitrogen magnetic steel will accumulate to the other side. When the bottom mesh plate is restored to be flat, the first motor is started to swing the cleaning mesh frame, so that the cleaning liquid on the surface of the samarium iron nitrogen magnetic steel can be better removed, thereby completing the cleaning process of the entire samarium iron nitrogen magnetic steel.

[0012] A cleaning method for samarium iron nitrogen magnetic steel cleaning equipment comprises the following steps: Step 1: Gently brush away the dust and impurities on the surface of the magnet, and carry out a series of pretreatment processes, then put the SmFeN magnet into the cleaning equipment from the magnet entrance opened at the top of the cleaning tank; Step 2: Place the SmFeN magnet from one end of the cleaning screen frame onto the bottom screen plate. At this time, the second motor on one side of the cleaning screen frame can be started to drive the first threaded rod, the second threaded rod and the third threaded rod on the outer wall of the second drive shaft to rotate, which will drive the two moving blocks to move on the first threaded rod, the second threaded rod and the third threaded rod, so that the pull rod will gradually squeeze the second connecting seat located at the top of the bottom screen plate downward, and at the same time, set the thread ratio of the first threaded rod, the second threaded rod and the third threaded rod, so that the bottom screen plate can remain tilted when moving downward, so that the SmFeN magnet can be laid flat to reduce accumulation, until the bottom screen plate is slid along the cleaning screen frame until it is at the bottom, so that the SmFeN magnet is completely immersed in the cleaning liquid; Step 3: After the SmFeN magnet enters the cleaning liquid, the first motor on one side of the cleaning tank is started to drive the rocker on the outer wall of one of the rotating shafts to rotate, so that the ring can slide up and down on the cylinder. Under the support of the pillar, the two connecting rods can swing on both sides, thereby driving the cleaning screen frame of the first connecting seat at the other end of the two connecting rods to move and shake, and at the same time, the other side of the cleaning screen frame performs the same swing. In the case of swinging, the spring between the first fixed seat on the front and rear end surfaces of the cleaning screen frame and the second fixed seat fixed on the inner wall of the front and rear end of the cleaning tank will stretch and extend forward, and the SmFeN magnet will be cleaned during the swinging process; Step 4: When the SmFeN magnet is cleaned, stop the movement of the first motor, and start the second motor to move the bottom screen upward, thereby driving the SmFeN magnet to move upward. Due to the ratio of the first threaded rod, the second threaded rod and the third threaded rod, the bottom screen can maintain a certain inclination as it moves, so that the SmFeN magnet can be gathered for easy collection. Then, when the bottom screen reaches a certain height and is separated from the cleaning liquid, the SmFeN magnet can be processed, and then the first motor is started to swing the cleaning screen frame to reduce the residual cleaning liquid on the surface of the SmFeN magnet.

[0013] The beneficial effects of the present invention are as follows: (1) The present invention designs a swing mechanism, a fixing mechanism and a lifting mechanism, so that the samarium iron nitrogen magnet can be better collected and cleaned during cleaning, and can increase the cleaning area of ​​the samarium iron nitrogen magnet by swinging left and right during cleaning, thereby greatly improving the cleaning efficiency; (2) The present invention designs a swing mechanism and a fixing mechanism, so that when the samarium iron nitrogen magnet is cleaned, the flow speed of the cleaning liquid can be accelerated by swinging, thereby impacting the samarium iron nitrogen magnet. The flow of the cleaning liquid allows the cleaning agent to cover each area more evenly, thereby improving the overall cleaning effect. In addition, the impact and swing of the cleaning liquid can weaken the friction between the samarium iron nitrogen magnets. The magnetism of the SmFeN magnets is increased, and the contact area between the SmFeN magnets is reduced. Reducing the magnetism between the SmFeN magnets can reduce the force of mutual attraction and reduce the physical collision and damage that may be caused during the cleaning process, thereby greatly improving the safety and cleaning efficiency of the SmFeN magnets during cleaning; (3) The present invention designs a swing mechanism and a lifting mechanism, which can lay the SmFeN magnets as they descend and slide and collect them when they rise. The gradual tilting can improve the placement efficiency in a limited space, making the cleaning and collection process more efficient. At the same time, after the SmFeN magnets are cleaned, they can be swung left and right. When swinging, the air flow increases, which helps to accelerate the drying process.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] like Figure 1-Figure 9As shown, a samarium iron nitrogen magnetic steel cleaning device includes a cleaning pool 1, a bracket 2 is fixedly connected to the bottom of the cleaning pool 1, a magnetic steel entrance 3 is opened on the top of the cleaning pool 1, a swing mechanism 4 is installed inside the cleaning pool 1, and the swing mechanism 4 includes a first motor 401 fixedly connected to one side of the cleaning pool 1, and rotating shafts 402 are rotatably connected inside the two sides of the cleaning pool 1, and the outer walls of the two rotating shafts 402 are fixedly connected to rockers 403, and the other ends of the two rockers 403 are rotatably connected to collars 404, and the inner walls of the two collars 404 are slidably connected to cylinders 405, and the upper and lower ends of the two cylinders 405 are fixedly connected to connecting rods 406, and the middle ends of the multiple connecting rods 406 are rotatably connected to the brackets. The other ends of the plurality of connecting rods 406 are rotatably connected to the first connecting seat 408, the outer walls of the two pillars 407 are fixedly connected to the fixing plates 409, the other end of one of the rotating shafts 402 is fixedly connected to the first motor 401, the upper and lower ends of one of the pillars 407 are fixedly connected to the cleaning tank 1, the bottom of the other cleaning tank 1 is fixedly connected to the cleaning tank 1, and the front and rear ends of the two fixing plates 409 are fixedly connected to the cleaning tank 1. When in use, after the samarium iron nitrogen magnet is placed in the cleaning equipment, the swing mechanism 4 can be used to swing it, so that the samarium iron nitrogen magnet can be completely in contact with the cleaning liquid, and the flow of the cleaning liquid can be increased by shaking, so that the samarium iron nitrogen magnet It can be completely rinsed, and for magnetic steel with complex shapes, shaking can help the cleaning agent penetrate into hard-to-reach areas. In addition, swinging can keep the cleaned magnetic steel evenly distributed on the screen to avoid stacking or mutual adsorption, which is convenient for subsequent operations. Specifically, the first motor 401 on one side of the cleaning tank 1 is started to drive the rocker 403 on the outer wall of one of the rotating shafts 402 to rotate. At this time, the rocker 403 makes a circular motion, so that the ring 404 can slide up and down on the cylinder 405. Under the support of the pillar 407, the two connecting rods 406 can swing on both sides, thereby driving the first connecting seat 408 at the other end of the two connecting rods 406. The cleaning screen frame 501 moves and shakes. At this time, the swing of the cleaning screen frame 501 can increase the internal flow of the cleaning liquid, and can better clean the samarium iron nitrogen magnetic steel. At the same time, the other side of the cleaning screen frame 501 is performing the same swing. The swinging of the two ends can better support the cleaning screen frame 501 on the one hand, and on the other hand, it uses the pillar 407 as a support to complete a moving and shaking process. In the case of swinging, the spring 503 between the first fixed seat 502 on the front and rear end surfaces of the cleaning screen frame 501 and the second fixed seat 504 fixed on the inner wall of the front and rear end of the cleaning tank 1 will stretch and extend forward, so that the samarium iron nitrogen magnetic steel can be better spread inside.

[0018] like Figure 4-Figure 5As shown, a fixing mechanism 5 is installed on one side of the swing mechanism 4, and the fixing mechanism 5 includes a cleaning screen frame 501 fixedly connected to one side of a plurality of first connecting seats 408, and two first fixing seats 502 are fixedly connected to the front and rear end surfaces of the cleaning screen frame 501, and springs 503 are fixedly connected inside the plurality of first fixing seats 502, and the other ends of the plurality of springs 503 are fixedly connected to second fixing seats 504, and one ends of the plurality of second fixing seats 504 are respectively fixedly connected to the inner walls of the front and rear ends of the cleaning tank 1.

Specifically, when the cleaning screen frame 501 is shaking, the springs 503 fixed by the first fixing seats 502 on the front and rear sides of the cleaning screen frame 501 are connected to the second fixing seats 504, so that the cleaning screen frame 501 slides within a certain range of the cleaning tank 1, avoiding collision between the cleaning tank 1 and the cleaning screen frame 501, and reducing the safety hazards of the cleaning equipment.

The outer wall of the wide thread 607 is rotatably connected to the third threaded rod 605, and the outer wall of the narrow thread 608 is rotatably connected to the second threaded rod 604. The outer wall of the bottom mesh plate 611 is slidably connected to the cleaning mesh frame 501. Before the samarium iron nitrogen magnet is placed into the cleaning equipment, it is necessary to use the lifting mechanism 6 to place it smoothly to avoid collision between the cleaning liquid and the samarium iron nitrogen magnet and waste of cleaning liquid. At the same time, the lifting mechanism 6 can be tilted during the placement process, so that the samarium iron nitrogen magnet can slide according to the slope and its own gravity. The tilting can reduce the contact area between the magnets, reduce the attraction between them, prevent mutual adsorption or stacking, and facilitate cleaning. Washing and processing, at the same time, after cleaning, it can be tilted to the other side, so that the samarium iron nitrogen magnetic steel can be stacked, which is more convenient for operators to collect, making the cleaning and picking process more efficient. In addition, after cleaning is completed, it can cooperate with the swing mechanism 4 to swing the cleaning liquid remaining on the surface of the samarium iron nitrogen magnetic steel to reduce the residue on the surface of the samarium iron nitrogen magnetic steel. Specifically, after the samarium iron nitrogen magnetic steel is placed on the bottom mesh plate 611, the second motor 601 on one side of the cleaning mesh frame 501 can be started to drive the first threaded rod 603, the second threaded rod 604 and the third threaded rod 605 on the outer wall of the second drive shaft 602 to rotate, and the thread groove of the outer wall of the third threaded rod 605 is set to one section, the thread groove of the outer wall of the second threaded rod 604 is set to three sections, and the thread groove of the outer wall of the first threaded rod 603 is set to three sections. The groove is set to four sections, and the length of the third threaded rod 605 is equal to that of the second threaded rod 604, and the length of the third threaded rod 605 and the second threaded rod 604 is equal to that of the first threaded rod 603. In addition, the narrow thread 608 of the wide thread 607 arranged on the inner wall of the moving block 606 rotates with the corresponding third threaded rod 605 and the second threaded rod 604 respectively, and the internal thread of another moving block 606 rotates with the first threaded rod 603 to ensure the engagement performance of the rotation. At the same speed, the moving distances of the two moving blocks 606 will be different, which will drive the bottom mesh plate 611 connected to the bottom of the second connecting seat 610 corresponding to different pull rods 609 to tilt, so that the samarium iron nitrogen magnet can slide. Similarly, when rising, the samarium iron nitrogen magnet will accumulate to the other side.When the bottom screen 611 is restored to be flat, the first motor 401 is started to swing the cleaning screen frame 501, so that the cleaning liquid on the surface of the SmFeN magnetic steel can be better removed, thus completing the entire cleaning process of the SmFeN magnetic steel.

[0020] A cleaning method for samarium iron nitrogen magnetic steel cleaning equipment comprises the following steps: Step 1: Gently brush away the dust and impurities on the surface of the magnetic steel, and perform a series of pretreatment processes, and then put the samarium iron nitrogen magnetic steel into the cleaning equipment through the magnetic steel inlet 3 opened at the top of the cleaning tank 1; Step 2: Place the SmFeN magnet from one end of the cleaning screen frame 501 onto the bottom screen plate 611. At this time, the second motor 601 on one side of the cleaning screen frame 501 can be started to drive the first threaded rod 603, the second threaded rod 604 and the third threaded rod 605 on the outer wall of the second driving shaft 602 to rotate, which will drive the two moving blocks 606 to move on the first threaded rod 603, the second threaded rod 604 and the third threaded rod 605, so that the pull rod 609 will gradually squeeze the second connecting seat 610 located at the top of the bottom screen plate 611 downward, and at the same time, set the thread ratio of the first threaded rod 603, the second threaded rod 604 and the third threaded rod 605, so that the bottom screen plate 611 can remain tilted when moving downward, so that the SmFeN magnet can be laid flat to reduce accumulation, until the bottom screen plate 611 is slid along the cleaning screen frame 501 until it is at the bottom, so that the SmFeN magnet is completely immersed in the cleaning liquid; Step 3: After the SmFeN magnet enters the cleaning liquid, the first motor 401 on one side of the cleaning tank 1 is started to drive the rocker 403 on the outer wall of one of the rotating shafts 402 to rotate, so that the ring 404 can slide up and down on the cylinder 405. Under the support of the pillar 407, the two connecting rods 406 can swing on both sides, thereby driving the cleaning net frame 501 of the first connecting seat 408 at the other end of the two connecting rods 406 to move and shake, and at the same time, the other side of the cleaning net frame 501 performs the same swing. In the case of swinging, the spring 503 between the first fixed seat 502 on the front and rear end surfaces of the cleaning net frame 501 and the second fixed seat 504 fixed on the inner wall of the front and rear end of the cleaning tank 1 will stretch and extend forward, and the SmFeN magnet is cleaned during the swinging process; Step 4: When the SmFeN magnet is cleaned, the movement of the first motor 401 is stopped, and the second motor 601 is started at this time, so that the bottom mesh plate 611 moves upward, thereby driving the SmFeN magnet to move upward. Due to the proportion of the first threaded rod 603, the second threaded rod 604 and the third threaded rod 605, as the bottom mesh plate 611 moves, it can maintain a certain inclination, so that the SmFeN magnet can be gathered for easy collection. Then, when the bottom mesh plate 611 reaches a certain height and is separated from the cleaning liquid, the SmFeN magnet can be processed, and then the first motor 401 is started to swing the cleaning mesh frame 501, so that the residual cleaning liquid on the surface of the SmFeN magnet is reduced.

7. The SmFeN magnetic steel cleaning equipment according to claim 6, characterized in that: The outer wall of the wide thread (607) is rotatably connected to the third threaded rod (605), the outer wall of the narrow thread (608) is rotatably connected to the second threaded rod (604), and the outer wall of the bottom screen plate (611) is slidably connected to the cleaning screen frame (501).

8. The cleaning method of samarium iron nitrogen magnetic steel cleaning equipment according to any one of claims 1 to 7, characterized in that: The following steps are involved: Step 1: Gently brush away the dust and impurities on the surface of the magnetic steel, and perform a series of pretreatment processes, and then put the samarium iron nitrogen magnetic steel into the cleaning equipment through the magnetic steel inlet (3) opened at the top of the cleaning tank (1); Step 2: Place the samarium iron nitrogen magnet from one end of the cleaning screen frame (501) onto the bottom screen plate (611). At this time, the second motor (601) on one side of the cleaning screen frame (501) can be started to drive the first threaded rod (603), the second threaded rod (604) and the third threaded rod (605) on the outer wall of the second drive shaft (602) to rotate, which will drive the two moving blocks (606) to move on the first threaded rod (603), the second threaded rod (604) and the third threaded rod (605), so that the pull The rod (609) gradually presses the second connection seat (610) located at the top of the bottom mesh plate (611) downward, and at the same time sets the thread ratio of the first threaded rod (603), the second threaded rod (604) and the third threaded rod (605) so that the bottom mesh plate (611) can be kept tilted when moving downward, so that the samarium iron nitrogen magnetic steel can be laid flat to reduce accumulation, until the bottom mesh plate (611) is slid along the cleaning mesh frame (501) until it is located at the bottom, so that the samarium iron nitrogen magnetic steel is completely immersed in the cleaning liquid; Step 3: After the samarium iron nitrogen magnet enters the cleaning liquid, the first motor (401) on one side of the cleaning tank (1) is started to drive the rocker (403) on the outer wall of one of the rotating shafts (402) to rotate, so that the ring (404) can slide up and down on the cylinder (405). Under the support of the pillar (407), the two connecting rods (406) can swing on both sides, thereby driving the cleaning screen frame (501) of the first connecting seat (408) at the other end of the two connecting rods (406) to move and shake. At the same time, the other side of the cleaning screen frame (501) performs the same swing. In the case of swinging, the spring (503) between the first fixed seat (502) on the front and rear end surfaces of the cleaning screen frame (501) and the second fixed seat (504) fixed on the front and rear end inner walls of the cleaning tank (1) will stretch and extend forward, and the samarium iron nitrogen magnet will be cleaned during the swinging process; Step 4: After the SmFeN magnet is cleaned, the movement of the first motor (401) is stopped, and the second motor (601) is started to move the bottom screen (611) upward, thereby driving the SmFeN magnet to move upward. Due to the proportions of the first threaded rod (603), the second threaded rod (604) and the third threaded rod (605), the bottom screen (611) can maintain a certain inclination during the movement process, so that the SmFeN magnet can be gathered and collected. Then, when the bottom screen (611) reaches a certain height and is separated from the cleaning liquid, the SmFeN magnet can be processed, and then the first motor (401) is started to swing the cleaning screen frame (501), so that the cleaning liquid residue on the surface of the SmFeN magnet is reduced.
