Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydrometallurgical electrolysis technology, and in particular to an electrolytic cell that facilitates liquid level adjustment. Background Technology
[0002] In hydrometallurgical electrolytic production processes, such as copper electrolysis, nickel electrowinning, cobalt electrowinning, and manganese electrolysis, the electrolytic cell is the core equipment, and the control of the electrolyte level within the cell is crucial. Maintaining a suitable electrolyte level ensures that the electrolyte level covers the effective deposition height of the cathode, thereby ensuring that the area of the metal deposit meets production requirements.
[0003] Taking copper electrolysis as an example, during the electrolysis process, to reduce the upper edge particles of the cathode copper, the electrolyte level in the electrolytic cell needs to be raised at the end of the electrolysis process, and then lowered before exiting the cell. Similarly, in the production processes of nickel electrowinning, cobalt electrowinning, and manganese electrolysis, the output of the anolyte needs to be controlled by adjusting the difference between the cathode and anode levels to maintain a balance between the inflow of cathode solution and the outflow of anolyte. This requires that the solution level in the electrolytic cell can be flexibly adjusted according to production needs.
[0004] Currently, the liquid level in an electrolytic cell is mainly adjusted using a level regulator. Typically, an overflow pipe is installed at the overflow hopper of the electrolytic cell, and the level regulator is mounted on the overflow pipe. The electrolyte in the cell flows out from the level regulator at the top of the overflow pipe. Existing level regulators and overflow pipes are mostly connected by threads. The liquid level in the electrolytic cell is adjusted by rotating the level regulator to raise or lower it.
[0005] However, this traditional spiral level regulator has revealed many problems in actual use, seriously affecting the stability and efficiency of production:
[0006] 1. Scale and crystallization affect rotation: During copper electrolysis, substances such as arsenic, antimony, and bismuth precipitate as scale. In processes such as copper electrowinning, nickel electrowinning, cobalt electrowinning, zinc electrowinning, and manganese electrolysis, crystallization occurs in the solution. This scale and crystals easily adhere to the threads of the level regulator, obstructing their rotation and preventing the level regulator from rising or falling normally, thus hindering level adjustment. To solve this problem, the threads need to be cleaned regularly, which is cumbersome and increases production costs.
[0007] 2. Lack of Measurement and Standardization in Liquid Level Adjustment: The use of threaded adjustment for liquid level control lacks effective measurement methods. Due to the lack of a unified reference standard, adjustments by operators often vary from person to person. This heavily relies on the operator's skill and experience, especially in processes like nickel electrowinning and cobalt electrowinning where liquid level control is crucial. Different anode and cathode level differences can lead to variations in anolyte output, affecting solution volume balance and introducing instability into production.
[0008] 3. Low level adjustment accuracy: Existing level adjustment methods are difficult to accurately determine whether the level has been adjusted to the correct position, which cannot meet the needs of some production processes that require high level accuracy, and may lead to problems such as unstable product quality or low production efficiency.
[0009] In conclusion, developing an electrolytic cell that can overcome the above-mentioned defects and facilitate liquid level adjustment is of great practical significance. Utility Model Content
[0010] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an electrolytic cell that is easy to adjust the liquid level.
[0011] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0012] An electrolytic cell with easily adjustable liquid level includes a cell body and an overflow port disposed at the top of the cell body. A liquid level regulator is disposed on the overflow port, the liquid level regulator comprising:
[0013] A base fixed to the overflow port, having a through hole communicating with the overflow port; and,
[0014] Multiple adjusting rings, each adjusting ring having a central channel communicating with the through hole;
[0015] The regulating rings are detachably stacked on the base, and the liquid level of the electrolyzer is adjusted by increasing or decreasing the number of regulating rings.
[0016] Furthermore, the top end of the adjusting ring and the top end of the base are provided with an upper connecting structure having the same structure, and the bottom end of the adjusting ring is provided with a lower connecting structure, which is adapted to the upper connecting structure.
[0017] Furthermore, one of the upper connecting structures and the lower connecting structure is an annular tenon with a first mating surface on its outer circumference; the other is an annular mortise with a second mating surface on its inner circumference that matches the first mating surface.
[0018] Furthermore, a rotating locking pin is provided between the annular tenon and the annular mortise. The rotating locking pin includes a first protruding edge disposed on the first mating surface and a second protruding edge disposed on the second mating surface. When the annular mortise is nested on the annular tenon, the first and second protruding edges are misaligned in height, and the first and second protruding edges are engaged by rotation.
[0019] Furthermore, a snap-fit structure is provided between the annular tenon and the annular mortise. The snap-fit structure includes a protrusion on the first mating surface and a groove on the second mating surface. The protrusion can be tightly fitted into the groove.
[0020] Furthermore, a plurality of protrusions are uniformly provided circumferentially on the first mating surface, and a plurality of grooves are correspondingly provided on the second mating surface.
[0021] Furthermore, the bottom end of the base is connected to the overflow port by adhesive or threaded connection.
[0022] Furthermore, all the adjusting rings have the same height.
[0023] Furthermore, the height of the adjusting ring is 5mm-50mm.
[0024] Furthermore, an overflow hopper is provided at the overflow outlet.
[0025] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects:
[0026] 1. This invention utilizes a base fixed to the overflow port to detachably stack multiple adjusting rings, allowing for level regulation of the electrolytic cell by increasing or decreasing the number of adjusting rings. This structure eliminates the threaded portion prone to scaling and crystallization, as is common in traditional threaded adjustment methods, thus avoiding interference from scaling and crystallization in level regulation. Therefore, the need for frequent thread cleaning as in traditional methods is eliminated, significantly reducing maintenance costs, minimizing production downtime due to equipment maintenance, improving production continuity and stability, and bringing significant economic benefits to the enterprise.
[0027] 2. This invention adjusts the liquid level by adding or removing a specific number and specification of adjusting rings. The height of each adjusting ring is fixed (all adjusting rings have the same height and can be set within a preset range). Operators can accurately determine the number of adjusting rings to add or remove according to production needs, thereby achieving standardization and precision in liquid level adjustment. This standardized operation method does not rely on the individual skills and operational level of the operators, reducing the impact of human factors on liquid level adjustment. It ensures that the solution level in the electrolytic cell can be accurately adjusted to the required position under different production batches and production conditions, maintaining a stable anode-cathode liquid level difference, ensuring the balance of anolyte output and solution volume, thereby improving product quality and production stability, and meeting the requirements of high-precision production processes.

[0059] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.
[0060] Example 1:
[0061] like Figures 1 to 8 As shown, this embodiment provides an electrolytic cell that facilitates liquid level adjustment. This electrolytic cell is mainly used in copper electrolysis production processes, but it is also applicable to hydrometallurgical processes such as nickel electrowinning, cobalt electrowinning, and manganese electrolysis.
[0062] The electrolytic cell 10 includes a cell body and an overflow port 11 located at the top of the cell body. An overflow hopper 12 is provided at the overflow port 11 to guide the electrolyte outflow. A liquid level regulator 20 is provided on the overflow port 11. The liquid level regulator 20 includes a base 21 fixed to the overflow port 11 and multiple regulating rings 22.
[0063] The base 21 is fixed to the overflow port 11 by a threaded connection. Specifically, the inner wall of the overflow port 11 is provided with an internal thread 111, and the bottom end of the base 21 is provided with an external thread 213 that matches the overflow port 11. By rotating the base 21, it can be securely installed on the overflow port 11. The base 21 is provided with a through hole 211 communicating with the overflow port 11 for the flow of electrolyte.
[0064] The adjusting ring 22 has a central channel 221 communicating with the through hole 211. The height of each adjusting ring 22 is the same and is set within the range of 5mm-50mm. In this embodiment, the height of the adjusting ring 22 is 10mm. The adjusting rings 22 are detachably stacked on the base 21. The liquid level of the electrolytic cell can be adjusted by increasing or decreasing the number of adjusting rings 22.
[0065] Both the top of the base 21 and the top of the adjusting ring 22 are equipped with upper connecting structures, such as upper connecting structure 212 on the top of the base 21 and upper connecting structure 222 on the top of the adjusting ring 22. The bottom of the adjusting ring 22 is equipped with a lower connecting structure 223. In this embodiment, the upper connecting structures 212 and 222 are annular tenons with a first mating surface on their outer circumference; the lower connecting structure 223 is an annular mortise with a second mating surface on its inner circumference that matches the first mating surface, and the depth of the annular mortise is the same as the height of the annular tenon. This structure allows the adjusting rings 22 to be accurately stacked on the base 21, and adjacent adjusting rings 22 can also be stably connected.
[0066] In the copper electrolysis production process, a certain liquid level needs to be maintained in the initial stage of electrolysis according to the production process requirements. At this time, a certain number of regulating rings 22 are stacked on the base 21. After the electrolyte overflows from the tank, it flows out of the overflow hopper 12 through the through hole 211 of the base 21 and the central channel 221 of the regulating rings 22. Since the height of the regulating rings 22 is fixed, the liquid level in the electrolytic cell will rise by 10mm for each additional regulating ring 22. Operators can accurately calculate the number of regulating rings 22 that need to be stacked according to production needs, so as to achieve standardized adjustment of the liquid level.
[0067] To reduce the number of particles along the upper edge of the cathode copper at the end of the electrolysis process, it is necessary to raise the liquid level in the electrolytic cell. This can be achieved by simply adding a corresponding number of regulating rings 22 to the existing ones. For example, if a 30mm increase in liquid level is required, three regulating rings 22 can be added. Conversely, when the liquid level needs to be lowered before discharge, the corresponding number of regulating rings 22 can be reduced to achieve the desired result.
[0068] This liquid level regulation method eliminates the threaded portion, which is prone to scaling and crystallization, found in traditional threaded regulation methods, fundamentally avoiding interference from scaling and crystallization in liquid level regulation. During copper electrolysis, although substances such as arsenic, antimony, and bismuth may precipitate as scale, since the liquid level regulator 20 in this embodiment has no threaded structure, scaling and crystallization will not affect the stacking and disassembly of the regulating ring 22. This eliminates the need for frequent thread cleaning as in traditional methods, significantly reducing maintenance costs, minimizing production downtime due to equipment maintenance, and improving production continuity and stability.
[0069] Simultaneously, the liquid level is adjusted by adding or removing a specific number and specification of adjusting rings 22. Each adjusting ring 22 has a fixed height, allowing operators to precisely determine the number of rings to add or remove based on production needs, thus achieving standardized and precise liquid level adjustment. This standardized operation method is independent of the individual skills and operational level of the operators, reducing the impact of human factors on liquid level adjustment. It ensures that the solution level in the electrolytic cell can be accurately adjusted to the required position under different production batches and conditions, maintaining a stable anode-cathode liquid level difference, ensuring the balance of anolyte output and solution volume, thereby improving product quality and production stability, and meeting the liquid level accuracy requirements of the copper electrolysis production process.
[0070] Example 2:
[0071] like Figures 9 to 16 As shown, the electrolytic cell of this embodiment is also applicable to the field of hydrometallurgical electrolysis technology, and performs particularly well in nickel electrowinning production processes.
[0072] Similar to Embodiment 1, the electrolytic cell 10 includes a cell body, an overflow port 11, and an overflow hopper 12. A liquid level regulator 20 is provided on the overflow port 11. The liquid level regulator 20 consists of a base 21 and multiple regulating rings 22.
[0073] The base 21 is fixed to the overflow port 11 by adhesive bonding. A special adhesive is applied to the contact surface between the base 21 and the overflow port 11 to ensure that the base 21 is firmly installed. The base 21 has a through hole 211 communicating with the overflow port 11, and the adjusting ring 22 has a central channel 221 communicating with the through hole 211. All adjusting rings 22 have the same height. In this embodiment, the height of the adjusting ring 22 is set to 20mm.
[0074] In this embodiment, the upper connecting structures 212 and 222 and the lower connecting structure 223 are configured differently from those in Embodiment 1. Both the upper connecting structure 212 of the base 21 and the upper connecting structure 222 of the adjusting ring 22 are annular mortises, while the lower connecting structure 223 is an annular tenon. The upper connecting structure 212 has a first protruding edge 2121, the upper connecting structure 222 has a first protruding edge 2221, and the lower connecting structure 223 has a second protruding edge 2231. A rotating locking pin is provided between the annular tenon and the annular mortise. When the annular mortise is nested in the annular tenon, the first protruding edges 2121 and 2221 and the second protruding edge 2231 are misaligned in height. By rotating the adjusting ring 22, the first protruding edges 2121 and 2221 are engaged with the second protruding edge 2231, thereby achieving a stable connection between the adjusting ring 22 and the base 21, as well as between adjacent adjusting rings 22.
[0075] In the nickel electrowinning process, liquid level control is crucial for product quality and production efficiency. At the start of production, the initial liquid level is determined according to process requirements, and a corresponding number of adjusting rings 22 are stacked on the base 21. During stacking, the annular tenon of the adjusting ring 22 is inserted into the annular groove of the base 21 or the adjusting ring 22 below it, causing the first protruding edge 2121 and the second protruding edge 2231 to misalign. Then, the adjusting ring 22 is rotated to engage the first protruding edge 2121 with the second protruding edge 2231, ensuring a secure connection. After the electrolyte overflows from the tank, it flows out from the overflow hopper 12 through the through hole 211 of the base 21 and the central channel 221 of the adjusting ring 22.
[0076] During production, the anode and cathode liquid level difference needs to be adjusted according to the actual situation to control the anolyte output, in order to maintain the balance between the cathode liquid inflow and the anolyte output. At this time, the liquid level is adjusted by increasing or decreasing the number of regulating rings 22. If it is necessary to raise the liquid level, the regulating rings 22 are added according to the stacking and snapping method described above; if it is necessary to lower the liquid level, the regulating rings 22 are rotated to separate them, and the corresponding number of regulating rings 22 are removed.
[0077] This liquid level adjustment method also avoids the shortcomings of traditional threaded adjustment methods. During nickel electrowinning, crystallization easily occurs in the solution. In traditional threaded adjustment methods, the threaded portion is prone to crystal adhesion, leading to obstructed rotation. However, the liquid level regulator 20 in this embodiment has no threaded structure. The adjustment ring 22 is connected via a rotary locking pin. Crystallization does not affect the disassembly and installation of the adjustment ring 22, eliminating the need for frequent cleaning, reducing maintenance costs, and improving production stability.
[0078] Furthermore, each adjusting ring 22 has a fixed height of 20mm, allowing operators to precisely calculate the number of adjusting rings 22 that need to be added or removed based on production requirements, thus achieving standardized and precise liquid level adjustment. Regardless of the operator's skill level, the liquid level can be accurately adjusted according to a unified standard, ensuring that a suitable anode-cathode liquid level difference is maintained at different production stages, guaranteeing the balance of anolyte output and solution volume, and improving the quality and production efficiency of nickel electrowinning products.
[0079] Example 3:
[0080] like Figures 17 to 24 As shown, the electrolytic cell in this embodiment is applied to the cobalt electrowinning process, providing a convenient and precise liquid level control solution for cobalt electrowinning production.
[0081] The basic structure of the electrolytic cell 10 is the same as that of the previous two embodiments, including a tank body, an overflow port 11 and an overflow hopper 12, and a liquid level regulator 20 is provided on the overflow port 11. The liquid level regulator 20 consists of a base 21 and multiple regulating rings 22.
[0082] The base 21 is fixed to the overflow port 11 by a threaded connection. The internal thread 111 on the inner wall of the overflow port 11 matches the external thread 213 at the bottom of the base 21. The base 21 is installed by rotation. The base 21 has a through hole 211 communicating with the overflow port 11. The adjusting ring 22 has a central channel 221 communicating with the through hole 211. All adjusting rings 22 have the same height. In this embodiment, the height of the adjusting ring 22 is 30mm.
[0083] In this embodiment, the upper connecting structure 212 of the base 21 and the upper connecting structure 222 of the adjusting ring 22 are both annular mortises, and the lower connecting structure 223 is annular tenons. A snap-fit structure is provided between the annular tenon and the annular mortises. This snap-fit structure includes a protrusion 2232 on the first mating surface of the annular tenon and a groove on the second mating surface of the annular mortises (grooves 2122 on the annular mortises of the base 21 and grooves 2222 on the annular mortises of the adjusting rings; the protrusion 2232 can be tightly fitted into the grooves 2122 and 2222). Furthermore, several protrusions 2232 are evenly distributed circumferentially on the first mating surface, and several grooves 2122 and 2222 are correspondingly distributed on the second mating surface. This multi-point snap-fit design makes the connection between the adjusting rings 22 more stable.
[0084] In the cobalt electrowinning process, the liquid level is initially set according to process requirements. After the base 21 is installed on the overflow port 11, the adjusting rings 22 are stacked on the base 21. During stacking, the annular tenon of the adjusting ring 22 is inserted into the annular groove of the base 21 or the adjusting ring 22 below, so that the protrusion 2232 fits tightly into the grooves 2122 and 2222, ensuring a firm connection. After the electrolyte overflows from the tank, it flows out from the overflow hopper 12 through the through hole 211 of the base 21 and the central channel 221 of the adjusting ring 22.
[0085] During production, the cobalt electrowinning process requires precise liquid level control. Different anode and cathode liquid level differences directly affect the anolyte output and solution volume balance, thus impacting product quality. Therefore, the liquid level needs to be adjusted promptly based on production conditions. When the liquid level needs to be increased, add adjusting rings 22, following the stacking and snap-fit method described above. When the liquid level needs to be decreased, forcefully pull the adjusting rings 22 upwards to separate the protrusions 2232 from the grooves 2222, and remove the corresponding number of adjusting rings 22.
[0086] The liquid level regulator 20 in this embodiment also overcomes the shortcomings of traditional threaded adjustment methods. Crystallization is common in the cobalt electrowinning process, and traditional threaded adjustment methods are prone to difficulties in thread rotation due to crystal adhesion, affecting liquid level regulation. However, this embodiment uses a snap-fit structure to connect the adjustment ring 22, eliminating the need for threads. Crystallization does not hinder the disassembly and installation of the adjustment ring 22, reducing maintenance costs, minimizing production downtime, and improving production continuity and stability.
[0087] Meanwhile, each adjusting ring 22 has a fixed height of 30mm. Operators can accurately calculate the number of adjusting rings 22 that need to be added or removed according to production needs, achieving standardized and precise liquid level adjustment. This standardized operation method does not rely on the personal factors of the operator and can ensure that the solution level in the electrolytic cell can be accurately adjusted to the required position under different production batches and production conditions, maintaining a suitable anode-cathode liquid level difference, ensuring the balance of anolyte output and solution volume, improving the quality and production stability of cobalt electrowinning products, and meeting the stringent requirements of liquid level accuracy in the cobalt electrowinning production process.
[0088] In summary, the three embodiments of this utility model achieve a stable connection between the adjusting ring and the base, as well as between the adjusting rings, through different connection structures. At the same time, by increasing or decreasing the number of adjusting rings, the liquid level of the electrolytic cell can be precisely adjusted, overcoming the defects of the traditional threaded adjustment method. This approach has significant economic benefits and production advantages, and is applicable to various hydrometallurgical electrolysis processes.
[0089] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
