Description

Technical Field

[0001] This invention relates to the field of electrode cleaning technology, specifically to an apparatus and method for dynamically immersing and cleaning electrolytic manganese dioxide electrodes. Background Technology

[0002] Electrolytic manganese dioxide plates are commonly used in battery manufacturing, particularly in lithium-ion batteries and battery energy storage systems. They are typically used in conjunction with electrolytes to form highly efficient battery systems. Cleaning electrolytic manganese dioxide plates is a crucial step in ensuring electrode performance and extending their lifespan.

[0003] For example, the patent document with authorization announcement number CN108539129B, authorization announcement date November 10, 2020, and titled "A Method for Washing Electrode Plates in Electrolytic Manganese Dioxide," includes the following steps: installing an air pipe in an immersion tank and evenly distributing air holes on the air pipe; placing the electrode plate to be washed in the immersion tank and injecting an immersion agent into the immersion tank; connecting gas to the air pipe, allowing the gas to rush into the immersion tank, generating a dynamic immersion liquid in the immersion tank, and continuously washing the surface of the electrode plate. This patent's method for washing electrode plates in electrolytic manganese dioxide utilizes gas to agitate and agitate the electrode plate immersion tank, improving the surface cleanliness of the electrode plate.

[0004] In the prior art, gas is used to agitate and agitate the electrode soaking tank to improve the surface cleanliness of the electrode. However, the agitation of the soaking tank by the gas is limited, and the flow direction of the soaking liquid in the soaking tank is relatively uniform as the gas moves from the bottom to the top of the soaking tank, resulting in many dead corners in the soaking tank that cannot be agitated by the gas. Summary of the Invention

[0005] The purpose of this invention is to provide an apparatus and method for dynamically immersing and cleaning electrolytic manganese dioxide plates, so as to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A device for dynamically immersing and cleaning electrolytic manganese dioxide electrode plates includes an immersion tank, wherein the immersion tank is provided with:

[0008] A circulating pipe has an outlet at one end and multiple inlets at the other end, and a circulating water pump is installed on the circulating pipe.

[0009] The dynamic circulation mechanism includes a blocking component for blocking multiple water inlets and a driving component for moving a water outlet. While the driving component moves the water outlet, the blocking component sequentially opens multiple water inlets so that one water outlet forms a circulation with different water inlets at different positions.

[0010] The above-mentioned device for dynamically immersing and cleaning electrolytic manganese dioxide electrode plates has multiple water inlet pipes fixed at one end of the circulation pipeline and a corrugated pipe fixed at the other end. The multiple water inlets are constructed on the multiple water inlet pipes, and the water outlet is constructed on the corrugated pipe.

[0011] The above-mentioned device for dynamically immersing and cleaning electrolytic manganese dioxide plates includes multiple ultrasonic generators installed at the bottom of the immersion tank.

[0012] The aforementioned device for dynamically immersing and cleaning electrolytic manganese dioxide electrode plates includes a sealing component comprising an extension constructed on the outer wall of an inlet pipe, a baffle hinged to the extension, and a torsion spring provided on the extension for forcing the baffle to seal the inlet.

[0013] The above-mentioned device for dynamically immersing and cleaning electrolytic manganese dioxide electrode plates includes a rotating shaft rotatably connected to the immersion tank, a plurality of protrusions on the outer wall of the rotating shaft, and abutment portions on the baffle plate, with the plurality of protrusions corresponding to the plurality of abutment portions.

[0014] In the aforementioned device for dynamically immersing and cleaning electrolytic manganese dioxide electrode plates, when the rotating shaft rotates, multiple protrusions sequentially abut against corresponding contact parts to sequentially open multiple water inlets. When one of the protrusions abuts against one contact part to open a corresponding water inlet, the remaining protrusions separate from their corresponding contact parts.

[0015] The aforementioned device for dynamically immersing and cleaning electrolytic manganese dioxide electrode plates includes a drive assembly comprising multiple drive wheels rotatably connected to the inner wall of the immersion tank, with a drive belt fitted onto each drive wheel, and the end of the corrugated pipe furthest from the circulation pipe being fixed to the drive belt.

[0016] In the aforementioned device for dynamically immersing and cleaning electrolytic manganese dioxide electrode plates, a drive shaft is fixed on one of the drive wheels, and the drive shaft is connected to the rotating shaft for transmission.

[0017] The aforementioned device for dynamically immersing and cleaning electrolytic manganese dioxide electrode plates includes an arc-shaped portion and a connecting column at the end of the drive shaft, a hemisphere on the rotating shaft, and multiple arc-shaped grooves and multiple adapter grooves on the hemisphere, with the multiple arc-shaped grooves and multiple adapter grooves arranged alternately.

[0018] A method for dynamically immersing and cleaning electrolytic manganese dioxide electrode plates, based on the apparatus for dynamically immersing and cleaning electrolytic manganese dioxide electrode plates described above, wherein when the circulating water pump is running, the driving component drives the water outlet to move, and at the same time, the sealing component sequentially opens multiple water inlets, so that one water outlet forms a circulation with different water inlets at different positions.

[0019] In the above technical solution, the present invention provides a device and method for dynamically immersing and cleaning electrolytic manganese dioxide electrode plates. When the circulating water pump is running, opening one water inlet through the sealing component can cooperate with the water outlet to make the liquid in the immersion tank circulate. During the process, opening different water inlets in sequence and moving the water outlet can change the path of liquid flow. In this way, a dynamic and all-round liquid circulation can be formed in the immersion tank. This can use the liquid flow to clean the electrode plates in all directions, realize a large circulation of water in all directions without dead angles, and maximize the cleaning effect of the electrode plates.

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Reference Figure 1-10 This invention provides a device for dynamically immersing and cleaning electrolytic manganese dioxide electrode plates, including an immersion tank 1. The immersion tank 1 is provided with a circulation pipe 2 and a dynamic circulation mechanism. One end of the circulation pipe 2 is configured as an outlet 3, and the other end is configured with multiple inlets 4. A circulation water pump 5 is provided on the circulation pipe 2. The dynamic circulation mechanism includes a blocking component for blocking the multiple inlets 4 and a driving component for moving the outlet 3. While the driving component moves the outlet 3, the blocking component sequentially opens the multiple inlets 4 so that one outlet 3 forms a circulation with different inlets 4 at different positions.

[0035] Specifically, the soaking tank 1 typically contains cleaning solution. Electrolytic manganese dioxide plates are then suspended into the soaking tank 1 to clean the plates through liquid flow and chemical reaction. This is existing technology and will not be elaborated upon here. The innovation of this embodiment lies in the inclusion of a circulation pipe 2 within the soaking tank 1. A circulating water pump 5 on the circulation pipe 2 allows the soaking solution in the soaking tank 1 to circulate between the inlet 4 and outlet 3 at both ends of the circulation pipe 2. The soaking tank 1 also includes a dynamic circulation mechanism, comprising a blocking component and a driving component. The blocking component can utilize a multi-electrode valve structure, as used in existing technologies. During operation, the multi-electrode valve structure can block or open a designated inlet 4. The driving component can utilize a linear drive structure, such as a lead screw or cylinder structure, which can drive the outlet 3. (That is, one end of the circulation pipe 2) moves back and forth in a straight line in the soaking tank 1; the advantage of this setting is that when the circulating water pump 5 is running, opening one inlet 4 through the sealing component can cooperate with the outlet 3 to make the liquid in the soaking tank 1 circulate. During the process, opening different inlets 4 in sequence and moving the outlet 3 can change the path of liquid flow. In this way, a dynamic and all-round liquid circulation can be formed in the soaking tank 1. This can use the liquid flow to clean the electrode plate in all directions, realize the all-round and dead-angle-free large circulation of water, and maximize the cleaning effect of the electrode plate.

[0036] Preferably, the direction of opening the inlet 4 in sequence is opposite to the direction of movement of the outlet 3, so that when the outlet 3 is on one side of the soaking tank 1, it can form a circulation with the inlet 4 on the other side, thereby increasing the flow path of the circulating water in the soaking tank 1 and further improving the cleaning effect on the electrode plate.

[0037] In another embodiment of the present invention, a plurality of water inlet pipes 6 are fixed at one end of the circulation pipe 2, and a corrugated pipe 7 is fixed at the other end. A plurality of water inlets 4 are constructed on the plurality of water inlet pipes 6, and a water outlet 3 is constructed on the corrugated pipe 7. Specifically, the circulation pump 5 is fixed to the outer wall of the soaking tank 1, and both ends are connected to the circulation pipe 2. One section of the circulation pipe 2 extends above the soaking tank 1 and is connected to the plurality of water inlet pipes 6, while the other section of the circulation pipe 2 is connected to the corrugated pipe 7. The end of the corrugated pipe 7 away from the circulation pipe 2 extends to the bottom of the soaking tank 1, so that the water inlet 4 and the water outlet 3 are located on the upper and lower sides of the soaking tank 1, respectively. Then, by operating the dynamic circulation mechanism, the soaking liquid can be fully circulated in the soaking tank 1.

[0038] Preferably, a plurality of ultrasonic generators 8 are provided at the bottom of the soaking tank 1. Specifically, a plurality of ultrasonic generators 8 are provided on the bottom wall of the soaking tank 1, which can further improve the cleaning effect of the electrode plates.

[0039] In another embodiment of the present invention, as an alternative to the solenoid valve structure used in the above-mentioned sealing component, preferably, the sealing component includes an extension 9 constructed on the outer wall of the inlet pipe 6, a baffle 10 hinged to the extension 9, and a torsion spring (not shown) provided on the extension 9 to force the baffle 10 to seal the inlet 4. Specifically, the extension 9 is located on one side of the inlet pipe 6, the baffle 10 is hinged to the extension 9 and adheres to the inlet 4 under the action of the torsion spring, so as to seal the inlet 4 by means of the baffle 10. With this setup, under normal conditions, multiple baffles 10 block multiple inlets 4 under the action of corresponding torsion springs. At this time, the circulating water pump 5 cannot circulate the liquid in the soaking tank 1 through the circulating pipe 2. When it is necessary to circulate the liquid in the soaking tank 1, the baffles 10 can be pushed against each other (e.g., manually or by an electric push rod) to overcome the spring force of the corresponding torsion springs and open the corresponding inlets 4. In this way, the liquid in the soaking tank 1 can be circulated by the circulating water pump 5. Subsequently, by pushing against different baffles 10 in sequence, the liquid in the soaking tank 1 can achieve dynamic circulation (the baffles 10 that lose contact will reset under the action of the corresponding torsion springs and re-block the corresponding inlets 4).

[0040] As an alternative to the above-mentioned method of opening the water inlet 4 by pushing the baffle 10 with an electric push rod, the soaking tank 1 is further provided with a rotating shaft 11 rotatably connected to it. The outer wall of the rotating shaft 11 has multiple protrusions 12, and the baffle 10 has contact parts 13. The multiple protrusions 12 correspond to the multiple contact parts 13. When the rotating shaft 11 rotates, the multiple protrusions 12 sequentially abut against their corresponding contact parts 13 to sequentially open the multiple water inlets 4. When one protrusion 12 abuts against one contact part 13 to open the corresponding water inlet 4, the remaining protrusions 12 separate from their corresponding contact parts 13. Specifically, the protrusion 12 has a structure consisting of a disc structure and a raised structure, such as... Figure 3 As shown, the protrusions 12 have different orientations; the baffle 10 on the side of the extension 9 near the water inlet pipe 6 extends to the water inlet pipe 6 to block the corresponding water inlet 4. The baffle 10 on the other side of the extension 9 has a contact part 13, which is located on the rotation stroke of the corresponding protrusion 12 (the protrusion on the protrusion 12). When the rotating shaft 11 rotates, it can drive the protrusion 12 to contact the corresponding contact part 13, so as to force the corresponding baffle 10 to overcome the elastic force of the torsion spring and open the corresponding water inlet 4. The multiple protrusions 12 correspond to the multiple contact parts 13 respectively, and the multiple protrusions 12 are located at different angles around the rotating shaft 11. In this embodiment, both the water inlet 4 and the protrusions 12 are provided. There are six protrusions 12, which are equidistantly arranged along the axial direction of the rotating shaft 11 to correspond to the positions of the six water inlets 4 (contact parts 13). Two adjacent protrusions 12 are spaced 60 degrees apart in the circumferential direction of the rotating shaft 11. When one protrusion 12 abuts against the corresponding contact part 13 to open the corresponding water inlet 4, the other protrusions 12 do not abut against the contact part 13. Then, the rotating shaft 11 rotates 60 degrees so that an adjacent protrusion 12 abuts against the corresponding contact part 13 to open the corresponding water inlet 4. Correspondingly, when the contact part 13 loses the contact of the protrusion 12, the baffle 10 resets under the action of the torsion spring to re-seal the corresponding water inlet 4. In this way, multiple water inlets 4 are opened sequentially during the rotation of the rotating shaft 11. The advantage is that during the rotation of the shaft 11, multiple protrusions 12 sequentially abut against multiple contact parts 13 to sequentially open multiple water inlets 4. Compared with the above embodiment which uses multiple solenoid valves or multiple electric push rods, this embodiment only requires a power source on the side wall of the soaking tank 1 to drive the shaft 11 to rotate, which can sequentially open multiple water inlets 4, thereby achieving the effect of cost reduction and efficiency improvement.

[0041] In another embodiment of the present invention, as an alternative to the aforementioned screw structure driving the outlet 3 to move, the driving assembly further includes multiple transmission wheels 14 rotatably connected to the inner wall of the soaking tank 1. A transmission belt 15 is fitted onto each of the multiple transmission wheels 14, and the end of the corrugated pipe 7 furthest from the circulation pipe 2 is fixed to the transmission belt 15. Specifically, the multiple transmission wheels 14 are located at multiple positions in the soaking tank 1. Taking four transmission wheels 14 as an example, the four transmission wheels 14 are located at the four corners of the soaking tank 1. The transmission belt 15 enables the four transmission wheels 14 to rotate synchronously and in the same direction. The end of the corrugated pipe 7 furthest from the circulation pipe 2 is located between two transmission wheels 14 furthest from the inlet pipe 6. Thus, when the transmission wheels 14 reciprocate, they drive the outlet 3 at the end of the corrugated pipe 7 to reciprocate between the two transmission wheels 14. In this embodiment, a motor structure (not shown) can be installed in the soaking tank 1. The motor structure can drive a transmission wheel 14 to rotate, thereby driving the outlet 3 at one end of the corrugated pipe 7 to move back and forth in the soaking tank 1 through the transmission wheel 14 and the transmission belt 15.

[0042] As an alternative to the aforementioned power source for the rotating shaft 11, preferably, a transmission shaft 16 is fixed on one of the transmission wheels 14, and the transmission shaft 16 is driveably connected to the rotating shaft 11. Specifically, in the above embodiment, the rotating shaft 11 and the transmission wheel 14 need to be provided with two power sources to drive them respectively. In this embodiment, a transmission shaft 16 is coaxially fixed on one of the transmission wheels 14, and the transmission shaft 16 extends to the rotating shaft 11 and is driveably connected to the rotating shaft 11. The transmission ratio between the transmission shaft 16 and the rotating shaft 11 is less than one. The transmission connection between the two can be a reduction gear transmission structure in the prior art. During the process of one power source driving one transmission wheel 14 to rotate, the transmission shaft 16 can drive the rotating shaft 11 to rotate at a reduced speed, and the rotational speed of the rotating shaft 11 is less than... The rotational speed of the drive shaft 16, that is, the drive shaft 16 rotates several times before the rotating shaft 11 rotates one revolution; taking six water inlets 4 as an example, during the process of the drive wheel 14 rotating several revolutions, the drive belt 15 can drive the water outlet 3 to move from one side of the soaking pool 1 to the other side, and at the same time, the drive shaft 16 can drive the rotating shaft 11 to rotate one revolution, so that multiple water inlets 4 are opened in sequence during the movement of the water outlet 3. Conversely, the power source drives the drive wheel 14 to rotate in the opposite direction, which can synchronously drive the water outlet 3 and the rotating shaft 11 to reset. This reciprocating motion can make the liquid in the soaking pool 1 dynamically circulate.

[0043] Furthermore, the drive shaft 16 has an arc-shaped portion 17 and a connecting post 18 at its end, and a hemisphere 19 is constructed on the rotating shaft 11. The hemisphere 19 has multiple arc-shaped grooves 20 and multiple fitting grooves 21, which are staggered. Specifically, in the above embodiment, rotating the rotating shaft 11 60 degrees opens different water inlets 4. During the continuous rotation of the drive shaft 16, the rotating shaft 11 and the drive gear maintain transmission and continue to rotate, causing multiple protrusions 12 to rotate continuously. Obviously, during the rotation of two adjacent protrusions 12 (during the sequential opening of two adjacent water inlets 4), the two adjacent water inlets 4 may open or close simultaneously (both situations will affect the circulation of the liquid, thus affecting the cleaning effect). Due to the continuous rotation of the rotating shaft 11, this situation will persist for a certain period of time. In this embodiment, the hemisphere 19 is similar to a bowl-shaped structure, with its opening facing the drive shaft 16. Multiple arc-shaped grooves 20 and multiple adapter grooves 21 are constructed on the side of the hemisphere 19 facing the drive shaft 16. The number of arc-shaped grooves 20 and adapter grooves 21 is the same as the number of inlets 4 (six in each case), and one arc-shaped groove 20 is adjacent to two adapter grooves 21, or one adapter groove 21 is adjacent to two arc-shaped grooves 20. The arc-shaped portion 17 is adapted to the arc-shaped groove 20, so that when the arc-shaped portion 17 rotates into the arc-shaped groove 20, it can restrict the hemisphere 19 to lock the rotating shaft 11. The connecting post 18 is located on the side of the drive shaft 16 away from the arc-shaped portion 17. During the rotation of the drive shaft 16, the arc-shaped portion 17 can rotate... The drive shaft 16 is inserted into an arc-shaped groove 20 to lock the rotating shaft 11. Then, the drive shaft 16 continues to rotate, which can drive the connecting post 18 to move into an adapter groove 21. At the same time, the arc-shaped part 17 moves out from the corresponding arc-shaped groove 20. At this time, the connecting post 18 and the inner wall of the adapter groove 21 abut against each other, so as to restrict the position of the hemisphere 19 by the connecting post 18. When the drive shaft 16 rotates, the connecting post 18 can abut against the inner wall of the adapter groove 21 to force the hemisphere 19 and the rotating shaft 11 to rotate until the hemisphere 19 and the rotating shaft 11 rotate 60 degrees. Then, the connecting post 18 moves out from the adapter groove 21. At the same time, the arc-shaped part 17 rotates into an adjacent arc-shaped groove 20, so as to restrict the hemisphere 19 and the rotating shaft 11 again by the arc-shaped part 17. The advantage of this design is that, during the continuous rotation of the drive shaft 16, the arc-shaped part 17 and the connecting column 18 can intermittently drive the hemisphere 19 and the rotating shaft 11 to rotate, so that the rotating shaft 11 can rotate 60 degrees when the drive wheel 14 rotates one revolution. This allows the outlet 3 to move a certain distance before switching to an inlet 4, thereby achieving dynamic liquid circulation. During the rotation of the rotating shaft 11 driven by the drive shaft 16, the connecting column 18 can drive the hemisphere 19 and the rotating shaft 11 to rotate 60 degrees quickly. Then, the arc-shaped part 17 locks the hemisphere 19 and the rotating shaft 11, thereby quickly and sequentially opening multiple inlets 4, minimizing the time when two adjacent inlets 4 open or close simultaneously, and maximizing the cleaning effect.

[0044] Furthermore, fan blades 22 are fixed on both the transmission wheel 14 and the transmission shaft 16. Specifically, in order to further reduce the dead zones of liquid circulation in the soaking tank 1, fan blades 22 are provided on multiple transmission wheels 14 and one transmission shaft 16. When the transmission wheels 14 and the transmission shaft 16 rotate, the multiple fan blades 22 can simultaneously agitate the liquid in the soaking tank 1, thereby cooperating with the circulation pipe 2 to enable the liquid to circulate dynamically and in all directions, further improving the cleaning effect. Optionally, the fan blades 22 on the transmission shaft 16 are symmetrically arranged with the fan blades 22 on the corresponding transmission wheels 14. When the transmission shaft 16 and the corresponding transmission wheels 14 rotate synchronously and in the same direction, the two fan blades 22 agitate the liquid in opposite directions, thereby increasing the degree of turbulence in the liquid flow in the soaking tank 1, further reducing the cleaning dead zones and improving the cleaning effect of the electrode plates.

[0045] The present invention also provides a method for dynamically immersing and cleaning electrolytic manganese dioxide electrode plates, which is based on the apparatus for dynamically immersing and cleaning electrolytic manganese dioxide electrode plates according to any of the above claims. When the circulating water pump 5 is running, the driving component drives the outlet 3 to move, and at the same time, the sealing component sequentially opens multiple inlets 4 so that one outlet 3 forms a circulation with different inlets 4 at different positions.

[0046] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
