Description

Technical Field

[0001] This application relates to the field of battery recycling technology, and in particular to an electrode plate electrolytic cell. Background Technology

[0002] In practical applications of related technologies, electrolytic recovery cells are typically used to recover lithium battery electrode plates. While this prevents the electrode plates from contacting each other and exposes a large area of ​​the plate to the electrolytic cell, thus increasing the electrolysis rate, the electrolytic performance of the electrolyte in the area where the electrode plate is located decreases because the electrolysis of the lithium battery electrode plates consumes specific components of the electrolyte. Currently, the electrode plates are fixed in one location within the electrolytic cell for electrolysis. During the electrolysis process, significant electrolyte consumption occurs around the electrode plate, and even with a stirrer in the cell, the impact on the electrolyte above the electrode plate is minimal, resulting in low electrolysis efficiency. Furthermore, since the existing supports for the electrode plates are fixed inside the electrolytic cell, the plates must be removed manually or with specific tools after electrolysis, making electrode plate replacement extremely inconvenient. Utility Model Content

[0003] In view of this, this application aims to provide an electrode plate electrolytic cell to improve the electrolysis efficiency of the electrode plate to be treated in the cell.

[0008] Furthermore, the drive unit includes a lifting mechanism disposed on the pool body and a rotating mechanism disposed on the lifting mechanism; the support plate is rotatably disposed on the lifting mechanism, and can be driven by the lifting mechanism to move up and down in the pool body, and can be driven by the rotating mechanism to rotate on the lifting mechanism.

[0009] Furthermore, the lifting mechanism includes a drive unit disposed on the outer wall of the pool body, a shift plate disposed inside the pool body, and a connecting frame connecting the drive unit and the shift plate; the bearing plate is rotatably disposed in a rotating groove on the shift plate, and the drive unit drives the shift plate to rise and fall in the pool body through the connecting frame.

[0010] Furthermore, the drive unit includes a first servo motor fixed to the outer wall of the pool body, a lead screw driven by the first servo motor, and an internal thread block fixed to the connecting frame; the internal thread block is screwed to the lead screw.

[0011] Furthermore, a lifting bracket is provided on the outer wall of the pool body, the lead screw is rotatably mounted on the lifting bracket, and a slider that can slide up and down is provided on the lifting bracket. The internal thread block and the connecting frame are both fixedly connected to the slider.

[0012] Furthermore, the connecting frame includes a top plate disposed on the top of the pool body, a transmission rod connecting the top plate and the slider, and a transition rod connecting the top plate and the shifting plate.

[0013] Furthermore, the pool body is cylindrical, and the top plate is constructed in an arc shape that matches the top edge of the pool body; a set of adapter rods is provided at each end of the top plate, and the transmission rod is connected to the middle position of the top plate.

[0014] Furthermore, the rotating mechanism includes a second servo motor mounted on the shift plate, and a gear that rotates under the drive of the second servo motor; the carrier disk is constructed in the shape of a disc, and the edge of the carrier disk is provided with a toothed belt; the gear meshes with the toothed belt to drive the carrier disk to rotate on the shift plate.

[0015] Compared with related technologies, this application has the following advantages:

[0016] (1) The electrode plate electrolytic cell of this application, by equipping the support plate in the cell with a driving unit to drive the support plate to move in the electrolyte in the cell, can make the electrode plate to be treated on the support plate change position with the support plate, so that the electrode plate to be treated can contact the electrolyte in different positions, so as to achieve full contact and smooth reaction between the electrode plate to be treated and the electrolyte; in this way, when the electrode plate to be treated consumes a specific component in the electrolyte in the current area through electrolysis, the electrode plate to be treated will move to other areas and continue to undergo electrolysis reaction with the electrolyte rich in the specific component; thereby effectively improving the electrolysis efficiency of the electrode plate to be treated in the cell.

[0017] (2) Multiple electrode arrangement slots are set up on the carrier plate in a centrally symmetrical and spaced manner, and the corresponding number of electrode plates to be treated are inserted and fixed into each electrode arrangement slot. This not only makes the electrode plates to be treated neat and uniformly distributed on the carrier plate, which is conducive to the contact between the electrode plates to be treated and the electrolyte, but also makes the placement and fixing of the electrode plates to be treated on the carrier plate simple and convenient, and facilitates the replacement and disassembly of the electrode plates to be treated.

[0018] (3) A power supply unit is fixedly set above the electrode plate to be treated relative to the carrier plate, which can provide the required power for the electrolysis of the electrode plate to be treated; the negative electrode rod is suspended on the electrode rod support, and the negative electrode rod can be easily immersed in the electrolyte next to the electrode plate to be treated. By utilizing the voltage difference between the electrode plate to be treated and the negative electrode rod, the electrode plate to be treated can be well promoted to carry out the electrolysis reaction, and finally create good voltage conditions for the electrolysis of the electrode plate to be treated.

[0019] (4) The drive unit is configured with a lifting mechanism and a rotating mechanism, which can respectively realize the driving control of lifting and rotating the carrier plate, thereby conveniently changing the height and angle position of the electrode plate to be treated in the pool, so as to achieve the purpose of fully contacting the electrolyte at different positions in the pool.

[0020] (5) By placing the drive unit of the lifting mechanism outside the pool body, the space occupied inside the pool body can be reduced, and there is no need to consider the corrosive effect of the electrolyte on the motor and other drive components in the drive unit, which facilitates the overall layout and installation of the lifting mechanism. The shift plate is placed inside the pool body. By setting a rotating groove on the shift plate, the bearing plate can be easily placed on the shift plate. The shift plate is connected to the drive unit through the connecting frame across the side wall of the pool body, thereby achieving the purpose of the drive unit driving the shift plate. The layout scheme of the entire lifting mechanism is simple and effective, and facilitates technical implementation.

[0021] (6) The transmission form of the motor-driven lead screw can reliably convert the motor rotation into lifting and lowering driving action; the lead screw drives the internal thread block to perform lifting and lowering action, and then drives the shift plate to perform lifting and lowering through the connecting frame; it has a good and stable transmission effect.

[0022] (7) A lifting bracket is installed on the outer wall of the pool body, which provides good conditions for the installation of the lead screw and the setting of the slider, and facilitates the specific setting and technical implementation of the drive unit.

[0023] (8) The connecting frame adopts a top plate, transmission rod and adapter rod structure. The connecting frame can cross the side wall of the pool body to realize the transmission connection between the drive unit located outside the pool body and the shift plate located inside the pool body. This avoids opening through slots and other structures on the side wall of the pool body, and will not damage the integrity of the pool body. This is conducive to ensuring the durability and reliability of the pool body.

[0024] (9) The pool body adopts a cylindrical structure, which is more suitable for setting both the shift plate and the support plate as discs, making it easier to realize the rotation drive action of the support plate on the shift plate; correspondingly, the top plate is set as an arc shape, so that when the shift plate descends to the bottom of the pool body, the top plate can press against the side wall of the pool body, which can reduce the load on the drive unit. Furthermore, a set of adapter rods is set at each end of the top plate. The bottom end of each set of adapter rods can be connected to the circumference of the shift plate through a connecting rod. The two sets of adapter rods and connecting rods are located on the symmetrical sides of the shift plate, which can make the force on the shift plate more balanced and help ensure the overall structural stability of the lifting support.

[0025] (10) The rotating mechanism adopts the form of motor-driven gear and gear and toothed belt meshing transmission on the bearing plate, which can achieve the effect of speed reduction transmission well and drive the bearing plate to rotate smoothly. Both have good driving and transmission effects. Attached Figure Description

[0042] As is well known, in the traditional electrolytic recycling process of electrode plates, the electrolytic performance of the electrolyte in the area where the lithium battery electrode plates are located decreases because specific components in the electrolyte are consumed during the electrolysis of the electrode plates. Currently, the electrode plates to be processed are fixed in one position within the electrolytic cell. During the electrolysis process, a significant amount of electrolyte is consumed around the electrode plates, and even with a stirrer in the cell, the impact on the electrolyte above the electrode plates is minimal, resulting in low electrolysis efficiency. Furthermore, since the existing supports for the electrode plates are fixed inside the electrolytic cell, the electrode plates must be removed from the cell by hand or with specific tools after electrolysis, making the replacement of the electrode plates extremely inconvenient.

[0043] In view of the above-mentioned problems in the related technologies, this application innovatively proposes a brand-new electrode plate electrolytic cell, which can improve the electrolysis efficiency of the electrode plate 3 to be treated in the cell body 1.

[0044] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0045] Embodiments of this application provide an electrode plate electrolytic cell for the electrolytic recycling of lithium batteries; one exemplary structure is as follows: Figure 1and Figure 2 As shown.

[0046] Overall, the electrode plate electrolytic cell includes a cell body 1, a support plate 2 for supporting the electrode plate 3 to be processed, and a drive unit disposed on the cell body 1. The support plate 2 is disposed within the cell body 1 via the drive unit, and the support plate 2 can move within the cell body 1 under the drive of the drive unit; as the support plate 2 moves, the electrode plate 3 to be processed located on the support plate 2 can change its position within the cell body 1, thus coming into contact with the electrolyte at different locations within the cell body 1.

[0047] Based on the overall design concept described above, by equipping the support plate 2 in the tank 1 with a driving unit to move the support plate 2 in the electrolyte within the tank 1, the electrode plate 3 to be treated on the support plate 2 can change position with the support plate 2, thereby allowing the electrode plate 3 to contact the electrolyte at different locations, achieving sufficient contact and smooth reaction between the electrode plate 3 and the electrolyte. In this way, after the electrode plate 3 consumes a specific component in the electrolyte in the current area through electrolysis, the electrode plate 3 will move to other areas to continue the electrolytic reaction with the electrolyte rich in the specific component. This can effectively improve the electrolysis efficiency of the electrode plate 3 in the tank 1.

[0048] It should be noted that, based on the above overall design concept, the technical solution of this application can adopt a variety of different specific implementation structures, forms, or configuration sequences. For example, the above-mentioned drive unit may include a lifting mechanism for changing the height position of the drive bearing plate 2, or a rotating mechanism for changing the angular position of the bearing plate 2, or a combination of multiple directional drive mechanisms; the pool body 1 may adopt different structural forms such as box-shaped or cylindrical. The specific arrangement sequence and assembly method of the pool body 1, drive unit, and bearing plate 2 can also be flexibly adjusted. For parts required for the implementation of the overall solution but not covered in the above overall setup, reasonable and flexible designs can be made by referring to mature setup methods in the field and the actual situation during implementation, which will not be elaborated here. The specific implementation schemes described below in this embodiment are only one of the many solutions that can be formed by the above various combinations and variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the many solutions that can be formed by the above-mentioned combinations and variations, as well as the specific implementation schemes of this embodiment, are all within the protection scope of this application.

[0049] Regarding the specific configuration of the carrier disk 2, there are naturally many different structural options available; for example, the carrier disk 2 can be designed as square or round, and the fixing structure of the electrode plate 3 to be processed on the carrier disk 2 can be a slot structure or a clamping fixing structure. In this embodiment, as... Figure 2As shown, in some preferred exemplary embodiments, the carrier disk 2 is provided with a plurality of electrode plate arrangement slots 20, and each electrode plate arrangement slot 20 is evenly distributed around the center of the carrier disk 2, and each electrode plate 3 to be processed is inserted into each electrode plate arrangement slot 20 in a corresponding manner.

[0050] Multiple electrode plate arrangement slots 20 are arranged in a centrally symmetrical and spaced manner on the carrier plate 2, and a corresponding number of electrode plates 3 to be treated are inserted and fixed into each electrode plate arrangement slot 20. This not only makes the distribution of the electrode plates 3 to be treated on the carrier plate 2 neat and uniform, which is conducive to the contact between the electrode plates 3 to be treated and the electrolyte, but also makes the placement and fixing of the electrode plates 3 to be treated on the carrier plate 2 simple and convenient, and facilitates the replacement and disassembly of the electrode plates 3 to be treated.

[0051] Still Figure 2 As shown, in some preferred exemplary embodiments, the electrode plate electrolytic cell of this embodiment further includes a power supply unit 4 fixedly disposed relative to the support plate 2. Specifically, the power supply unit 4 of this embodiment includes a power source 40 disposed above the electrode plate 3 to be treated and an electrode rod support 41, and a negative electrode rod 5 that can be immersed in the electrolyte is suspended on the electrode rod support 41; the positive and negative terminals of the power source 40 are respectively connected to the electrode plate 3 to be treated and the negative electrode rod 5. The power supply unit 4 is fixedly disposed above the electrode plate 3 to be treated relative to the support plate 2 to provide the required power for the electrolysis of the electrode plate 3 to be treated; the negative electrode rod 5 is suspended on the electrode rod support 41, and the negative electrode rod 5 can be easily immersed in the electrolyte located next to the electrode plate 3 to be treated. The voltage difference between the electrode plate 3 to be treated and the negative electrode rod 5 by the power source 40 can effectively promote the electrolytic reaction of the electrode plate 3 to be treated, and ultimately create good voltage conditions for the electrolysis of the electrode plate 3 to be treated.

[0052] As mentioned above, the type and number of drive units can be flexibly selected. In this embodiment, for example... Figure 1 , Figure 2 and Figure 3 As shown, in some preferred exemplary embodiments, the drive unit includes a lifting mechanism disposed on the pool body 1 and a rotating mechanism disposed on the lifting mechanism. The support plate 2 is rotatably disposed on the lifting mechanism and can be driven by the lifting mechanism to move up and down within the pool body 1; simultaneously, the support plate 2 can also be driven by the rotating mechanism to rotate on the lifting mechanism.

[0053] The drive unit is configured with a lifting mechanism and a rotating mechanism, which can respectively drive and control the lifting and rotation of the support plate 2. This allows for convenient changes in the height and angle of the electrode plate 3 to be treated within the tank 1, thus ensuring sufficient contact with the electrolyte at different locations within the tank 1. Furthermore, the lifting mechanism allows the support plate 2 to be moved to the open position at the top of the tank 1, eliminating the need to reach inside the tank 1 to disassemble or assemble the electrode plate 3. This facilitates the replacement and disassembly of the electrode plate 3 after electrolysis.

[0054] Specifically, such as Figure 1 , Figure 2 and Figure 3 and Figure 4 As shown, the lifting mechanism of this embodiment includes a drive unit disposed on the outer wall of the pool body 1, a shift plate 6 disposed inside the pool body 1, and a connecting frame connecting the drive unit and the shift plate 6. The support plate 2 is rotatably disposed in the rotating groove 61 on the shift plate 6, and the drive unit drives the shift plate 6 to rise and fall within the pool body 1 via the connecting frame.

[0055] By placing the drive unit of the lifting mechanism outside the pool body 1, the space occupied inside the pool body 1 can be reduced, and the corrosive effect of the electrolyte on the drive components such as the motor in the drive unit can be eliminated, which facilitates the overall layout and installation of the lifting mechanism. The shift plate 6 is set inside the pool body 1. By setting a rotating groove 61 on the shift plate 6, the bearing plate 2 can be easily placed on the shift plate 6. The shift plate 6 is connected to the drive unit through the connecting frame across the side wall of the pool body 1, thereby achieving the purpose of the drive unit driving the shift plate 6. The layout scheme of the entire lifting mechanism is simple and effective, and easy to implement.

[0056] In some preferred exemplary embodiments, the drive unit of this embodiment includes a first servo motor 79 fixedly mounted on the outer wall of the pool body 1, a lead screw 77 driven by the first servo motor 79, and an internally threaded block 76 fixedly connected to the connecting frame. The internally threaded block 76 is screwed to the lead screw 77. Under the drive of the first servo motor 79, the lead screw 77 rotates, thereby driving the internally threaded block 76 to move up and down. This motor-driven lead screw transmission method reliably converts motor rotation into lifting and lowering motion; the lead screw 77 drives the internally threaded block 76 to perform lifting and lowering motion, which in turn drives the shift plate 6 to lift and lower via the connecting frame; resulting in good and stable transmission performance.

[0057] Preferably, a lifting bracket 7 can be installed on the outer wall of the pool body 1, and a lead screw 77 can be rotatably mounted on the lifting bracket 7. A slider 71 that can slide up and down is also installed on the lifting bracket 7, and the internal thread block 76 and the connecting frame are both fixed to the slider 71. Specifically, the lifting bracket 7 can adopt a "U"-shaped frame structure, with both ends of the lead screw 77 rotatably passing through the two ends of the lifting bracket 7. The middle part of the lifting bracket 7 is welded to the outer wall of the pool body 1, and a vertically arranged sliding groove 710 is formed on the lifting bracket 7 to guide the slider 71 to slide within the groove 710. Installing the lifting bracket 7 on the outer wall of the pool body 1 provides favorable conditions for the installation of the lead screw 77 and the setting of the slider 71, facilitating the specific setup and technical implementation of the drive unit. To facilitate the installation of the first servo motor 79, a motor frame 78 can be added to the outer wall of the pool body 1 below the lifting bracket 7, and the first servo motor 79 can be mounted on the motor frame 78.

[0058] Still Figure 1 , Figure 2 and Figure 3 As shown, the connecting frame in this embodiment includes a top plate 73 disposed on the top of the pool body 1, a transmission rod 72 connecting the top plate 73 and the slider 71, and a transition rod 74 connecting the top plate 73 and the shift plate 6. The connecting frame adopts the structure of top plate 73, transmission rod 72 and transition rod 74. The connecting frame can span across the side wall of the pool body 1 to realize the transmission connection between the drive unit located outside the pool body 1 and the shift plate 6 located inside the pool body 1. This avoids the need to open through slots or other structures on the side wall of the pool body 1, does not damage the integrity of the pool body 1, and helps to ensure the durability and reliability of the pool body 1.

[0059] Based on the above configuration, preferably, the pool body 1 in this embodiment is designed as a cylinder, and the top plate 73 is constructed as an arc shape that matches the top edge of the pool body 1. Simultaneously, each end of the top plate 73 is provided with a set of adapter rods 74, and a transmission rod 72 is connected to the middle of the top plate 73. The cylindrical structure of the pool body 1 is more suitable for setting both the shift plate 6 and the support plate 2 as discs, facilitating the rotational drive action of the support plate 2 on the shift plate 6. Correspondingly, setting the top plate 73 as an arc shape allows it to press precisely against the side wall of the pool body 1 when the shift plate 6 descends to the bottom, reducing the load on the drive unit. Furthermore, a set of adapter rods 74 is set at each end of the top plate 73. The bottom end of each set of adapter rods 74 can be connected to the circumference of the displacement plate 6 through a connecting rod 75. The two sets of adapter rods 74 and connecting rods 75 are located on the symmetrical sides of the displacement plate 6, which can make the force on the displacement plate 6 more balanced and help ensure the overall structural stability of the lifting bracket 7.

[0060] There are, of course, various structural options available for the specific configuration of the rotating mechanism; for example, a rotary motor can be installed in the middle of the shift plate 6 to directly drive the carrier plate 2 to rotate on the shift plate 6. However, in this embodiment, as... Figure 2 and Figure 4 As shown, in some preferred exemplary embodiments, the rotating mechanism of this embodiment includes a second servo motor 67 mounted on the shift plate 6, and a gear 64 rotating under the drive of the second servo motor 67; meanwhile, the support plate 2 is constructed in a disc shape, and the edge of the support plate 2 is provided with a toothed belt 65. When the second servo motor 67 drives the gear 64 to rotate, since the gear 64 meshes with the toothed belt 65, the rotation of the gear 64 can drive the support plate 2 to rotate on the shift plate 6. The rotating mechanism adopts the form of motor driving gear 64, and gear 64 meshing with the toothed belt 65 on the support plate 2, which can achieve a good speed reduction transmission effect and drive the support plate 2 to perform a smooth rotation, both with good driving and transmission effects.

[0061] In the specific design, a mounting bracket 62 can be welded to the edge of the shift plate 6 to mount the second servo motor 67 onto the mounting bracket 62; the rotating shaft 63 of the second servo motor 67 can be rotatably mounted on the mounting bracket 62 and fixedly connected to the gear 64; since the second servo motor 67 will be immersed in the electrolyte for a long time, in order to improve the protection performance of the second servo motor 67, a sealed protective cover 66 can be wrapped around the outside of the second servo motor 67.

[0062] Based on the above exemplary embodiments, as a preferred combination of the exemplary solutions, refer to Figures 1 to 4 As shown, when implementing the electrode plate electrolytic cell of this application, the following overall implementation scheme can be referred to:

[0063] The electrode plate electrolytic cell of this application includes a cell body 1, a support plate 2, and a shifting plate 6. The support plate 2 is disposed inside the cell body 1, and an electrode plate 3 to be processed is mounted on the support plate 2. A power supply unit 4 is disposed on the top of the support plate 2 (above the electrode plate 3), and a negative electrode rod 5 is disposed on the power supply unit 4. A lifting mechanism is mounted on the cell body 1, and a rotating mechanism is mounted on the lifting mechanism. The rotating mechanism is mounted on the bottom of the support plate 2. The lifting mechanism includes the shifting plate 6, and both the support plate 2 and the rotating mechanism are mounted on the shifting plate 6. A rotating groove 61 is formed on the shifting plate 6. The carrier plate 2 is rotatably mounted in the rotating groove 61. A rotating shaft 63 is rotatably mounted on the shift plate 6. A gear 64 is sleeved on the rotating shaft 63. A toothed belt 65 meshes with the gear 64. The toothed belt 65 is sleeved on the edge of the carrier plate 2. A mounting bracket 62 is mounted on the shift plate 6. The rotating shaft 63 is rotatably mounted on the mounting bracket 62. A protective cover 66 is mounted on the mounting bracket 62. A second servo motor 67 is installed inside the protective cover 66. The output shaft of the second servo motor 67 is connected to the top end of the rotating shaft 63. The bottom end of the rotating shaft 63 is fixedly connected to the gear 64. The second servo motor 67 drives the rotating shaft 63 on the mounting bracket 62 to rotate. The rotating shaft 63 drives the gear 64 to rotate, the gear 64 drives the toothed belt 65 to rotate, and the toothed belt 65 drives the carrier plate 2 to rotate on the shift plate 6. This allows the electrode plate 3 to be processed on the carrier plate 2 to be rotated to different positions so that the electrode plate 3 to be processed can fully contact the surrounding electrolyte, realize the electrolysis of the electrode plate 3 to be processed, and thus accelerate the electrolysis speed of the electrode plate 3 to be processed.

[0064] Meanwhile, the lifting mechanism includes a lifting bracket 7, which is installed on the outer wall of the pool body 1. A slider 71 is slidably installed on the lifting bracket 7. A sliding groove 710 is opened on the lifting bracket 7, and the slider 71 is slidably installed in the sliding groove 710. A transmission rod 72 is installed on the slider 71, and a top plate 73 is installed on the transmission rod 72. A transition rod 74 is installed at both ends of the top plate 73. A connecting rod 75 is installed on each of the two transition rods 74. The two connecting rods 75 are respectively installed on both sides of the shift plate 6 and can be fixed to the circumference of the shift plate 6. Preferably, the arrangement is symmetrical about the center of the shift plate 6 to make the shift plate 6 bear the force evenly. A lead screw 77 is rotatably mounted on the lifting bracket 7. An internal threaded block 76 is screwed onto the lead screw 77. The internal threaded block 76 is mounted on one end of the slider 71. A motor frame 78 is mounted on the pool body 1. The motor frame 78 is bolted to fix a first servo motor 79. The output shaft of the first servo motor 79 is connected to the bottom end of the lead screw 77. The first servo motor 79 drives the output shaft to rotate, which in turn drives the lead screw 77 on the lifting bracket 7 to rotate. The lead screw 77 drives the internal threaded block 76 to move up and down. The internal threaded block 76 drives the slider 71 to slide up and down in the slide groove 710 on the lifting bracket 7. The slider 71 drives the transmission rod 72 to move. The transmission rod 72 drives the connecting rod 75 through the top plate 73 and the adapter rod 74. The connecting rod 75 moves the shifting plate 6 and its supporting plate 2, thereby immersing the electrode plate 3 to be treated on the supporting plate 2 at different heights in the pool 1. This allows the electrode plate 3 to be electrolyzed in the electrolyte at different positions. After the electrode plate 3 is electrolyzed, the first servo motor 79 drives the lead screw 77 to rotate in the opposite direction, which can easily move the electrode plate 3 on the supporting plate 2 from the electrolyte in the pool 1 to above the electrolyte. This makes it easy to disassemble and replace the electrode plate 3 on the supporting plate 2 from the outside, avoiding the need for workers to put their hands into the electrolyte when replacing the electrode plate 3, which can easily cause hand injuries.

[0065] The working principle of the entire electrode plate electrolytic cell is roughly as follows:

[0066] When using the electrolyte in the tank 1 to electrolyze and recover the electrode plates 3 to be treated, the electrode plates 3 to be treated are sequentially inserted into the support plate 2. The electrode plate arrangement groove 20 on the support plate 2 is used to clamp and fix the electrode plates 3 to be treated. Then, the switch of the first servo motor 79 is turned on, and the first servo motor 79 drives the output shaft to rotate. The output shaft drives the lead screw 77 on the lifting bracket 7 to rotate. The lead screw 77 drives the internal thread block 76 to rotate. The internal thread block 76 drives the slider 71 to slide upward in the slide groove 710 on the lifting bracket 7. The slider 71 drives the transmission rod 72 to move. The transmission rod 72 drives the top plate 73 to move. The top plate 73 drives the adapter rod 74 to slide on the inner wall of the tank 1. The adapter rod 74 drives the connection When rod 75 moves, it drives the carrier plate 2 on the shifting plate 6 to move, thus immersing the electrode plate 3 to be treated on the carrier plate 2 in the electrolyte in the pool 1 for electrolysis. Then, the switch of the second servo motor 67 inside the protective cover 66 is activated. The second servo motor 67 drives the rotating shaft 63 on the mounting frame 62 to rotate. The rotating shaft 63 drives the gear 64 to rotate, which in turn drives the toothed belt 65 to rotate. The toothed belt 65 drives the carrier plate 2 to rotate on the shifting plate 6, thereby rotating the electrode plate 3 on the carrier plate 2 to different positions for electrolysis. This ensures that the electrode plate 3 can fully contact the electrolyte at different positions, thereby accelerating the electrolysis speed. During electrolysis, the shifting plate 6 and the carrier plate 2 can also be moved upwards by a lifting mechanism to ensure that the electrode plate 3 can fully contact the electrolyte at different heights, further improving the electrolysis efficiency of the electrode plate 3.

[0067] In summary, the electrode plate electrolysis cell of this embodiment, by equipping the support plate 2 in the cell body 1 with a driving unit to drive the support plate 2 to move its position in the electrolyte within the cell body 1, allows the electrode plate 3 to be treated on the support plate 2 to change position with the support plate 2. This enables the electrode plate 3 to contact the electrolyte at different locations, achieving sufficient contact and smooth reaction between the electrode plate 3 and the electrolyte. In this way, after the electrode plate 3 consumes a specific component in the electrolyte in the current area through electrolysis, the electrode plate 3 will move to other areas to continue the electrolysis reaction with the electrolyte rich in the specific component. This effectively improves the electrolysis efficiency of the electrode plate 3 in the cell body 1.
