Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell technology, and specifically to a tooling base for assembling electrolytic cells. Background Technology

[0002] In fields such as electrolytic hydrogen production and metal electrolytic refining, the installation stability and positioning accuracy of electrolytic cells directly affect production efficiency, product purity, and operational safety. The tooling base is the core component supporting the electrolytic cell, and the support columns on it play a crucial role in height compensation, horizontal calibration, and load transfer. Its adaptability is essential for equipment compatibility and ease of operation and maintenance.

[0003] The existing support columns of the tooling base used for assembling electrolytic cells are mainly connected to the base by two methods: integrated welding or pre-drilled bolt fastening. Both of these methods result in the position, number, and height of the support columns being "rigidly limited" and cannot be dynamically adjusted according to the needs of electrolytic cells of different specifications.

[0004] Different types (such as alkaline, proton exchange membrane, and solid oxide electrolyzers) or different specifications of electrolyzers vary significantly in the distribution of support points and load-bearing capacity. Fixed support columns cannot accommodate these differences, which may lead to the following problems: First, poor equipment compatibility. One set of bases can only match a single specification of electrolyzer. When replacing an electrolyzer, the base must be remanufactured, which is costly and wasteful of old bases, failing to meet the requirements of cost reduction and low carbon emissions. Second, low installation and commissioning efficiency. Deviations in support points need to be adjusted by grinding and adding shims, which is cumbersome and difficult to guarantee accuracy, easily leading to unstable electrolytic reactions.

[0005] As electrolysis technology continues to develop towards larger scale and more diverse specifications, enterprises have an urgent need for multi-functional tooling bases. Existing fixed support column solutions have become a technical bottleneck, and there is an urgent need to develop tooling base structures with adjustable support column positions.

[0043] See Figures 1 to 5 The present invention discloses a tooling base for assembling an electrolytic cell, comprising: a base plate 100, a support column 200, and a movable structure 300.

[0044] The base plate 100 is provided with several support columns 200, which are used to support the electrolytic cell.

[0045] Specifically, the base plate 100, which serves as the load-bearing foundation of the entire tooling base, can be integrally formed from high-strength alloy steel. Its planar dimensions are designed according to the maximum specifications of common electrolytic cells, generally 2000mm×1500mm-4000mm×3000mm, with a thickness of not less than 20mm to ensure overall rigidity.

[0046] It should be noted that the upper surface of the base plate is precision milled, and the flatness error is controlled within 0.1mm / m to ensure the consistency of the horizontal reference during the movement of the support column 200.

[0047] As a preferred embodiment, a limiting baffle with a height of 50mm (not shown in the figure) may also be provided around the edge of the base plate 100 to prevent the support column 200 from leaving the working area of ​​the base plate 100 during movement.

[0048] It should be noted that the support column 200 contacts the end pressure plate 400 of the electrolytic cell to support the electrolytic cell. In this embodiment, the number of support columns 200 can be flexibly increased or decreased according to the specifications of the electrolytic cell. The load-bearing capacity of the support column 200 can be designed to be no less than 20,000 kg per column to meet the load-bearing requirements of various large electrolytic cells.

[0049] The movable structure 300 is connected to the base plate 100 and the support column 200.

[0050] In a preferred embodiment, the movable structure 300 includes a T-slot 301 and a locking device 302; the T-slot 301 is disposed on the base plate 100, and the locking device 302 is disposed on the support column 200; the locking device 302 drives the support column 200 to move through the through hole on the support column 200 and the T-slot 301.

[0051] Specifically, the movable structure 300 is connected to the base plate 100 and the support column 200, and consists of two parts: a T-slot 301 and a locking device 302. The T-slot 301 is radially distributed with the center of the base plate 100 as the origin, ensuring that the support column 200 can move smoothly from the central area to the edges in all directions.

[0052] Furthermore, the locking device 302 includes: a locking bolt 3021 and a T-nut 3022;

[0053] The locking bolt 3021 is installed on the support column 200 through the through hole, and the T-nut 3022 is installed in the T-slot 301.

[0054] Specifically, in this embodiment, the gap between the T-nut 3022 and the T-slot 301 is controlled within a reasonable range, such as 0.2-0.5mm, which ensures smooth movement without significant shaking. After the support column 200 moves to the target position, the locking bolt 3021 is tightened to fix the support column 200 on the base plate 100, ensuring that the support column 200 will not be displaced during operation.

[0055] The support column 200 can be moved along the central area of ​​the base plate 100 towards the edge of the base plate 100 via the movable structure 300.

[0056] Specifically, the support column 200 can be moved along the central area of ​​the base plate 100 towards its edge via the movable structure 300, covering the entire effective working area of ​​the base plate 100. When different sizes of electrolytic cells need to be installed, the locking devices 302 of all support columns 200 are first loosened, and the support column 200 is moved from the central area to the corresponding position along the radial guide rail according to the distribution of support points at the bottom of the electrolytic cell. This movement method makes the position adjustment of the support column 200 more flexible, adaptable to the support requirements of different types of electrolytic cells (such as alkaline electrolytic cells, proton exchange membrane electrolytic cells, etc.), while ensuring the accuracy and stability of the adjusted position, effectively solving the problem of poor adaptability of traditional fixed support columns 200.

[0057] In a preferred embodiment, the number of T-slots 301 is the same as the number of support columns 200, or is an integer multiple of the number of support columns 200.

[0058] Specifically, when the number of T-slots 301 is the same as the number of support columns 200, each support column 200 can independently correspond to a dedicated T-slot 301, forming a "one-to-one" matching relationship. This configuration method can ensure that each support column 200 does not interfere with each other during the movement and adjustment process, and is especially suitable for scenarios with extremely high requirements for the positional accuracy of the support points (such as the installation of semiconductor-grade high-purity hydrogen electrolyzers).

[0059] When the number of T-slots 301 is an integer multiple (such as 2 times or 3 times) of the number of support columns 200, the resulting "multiple slots corresponding to one support column 200" structure has a significant advantage in stability compared to "one slot and one column".

[0060] Enhanced anti-overturning capability: A single support column 200 can simultaneously engage with two parallel T-slots 301 (e.g., using a double slider connection structure), increasing the number of contact points between the support column 200 and the base plate 100 from one to two or three, forming a stable rectangular support surface. Actual measurement data shows that this structure improves the anti-overturning capability of the support column 200, ensuring positional stability even when lateral forces are generated during the assembly of the electrolytic cell.

[0061] More uniform load distribution: Multiple T-slots 301 allow the vertical load borne by the support column 200 to be distributed to the base plate 100 through multiple T-slots 301, reducing the stress on the T-slots 301. This distributed load-bearing mode can effectively avoid deformation caused by long-term stress on the T-slots 301.

[0062] Improved motion stability: Multiple T-slots 301 provide more comprehensive constraints on the support column 200 during movement, eliminating slight swaying that may occur when "one T-slot 301 corresponds to one support column 200". When fine-tuning the support position is required, this stability ensures that the height adjustment accuracy is not affected by the movement process, significantly reducing the workload of repeated calibration.

[0063] When using an integer multiple configuration, the T-slots 301 are still arranged radially with the center of the base plate 100 as the origin, and adjacent groups (each group contains the same number of T-slots 301 as the support columns 200) maintain a uniform angular interval. This layout ensures the symmetry of the trajectory of the support columns 200 as they move towards the edge, and also improves the fault tolerance of the system through multi-track redundancy design—even if a certain T-slot 301 wears out due to long-term use, the support column 200 can still move through other T-slots 301.

[0064] In a preferred embodiment, the support column 200 includes a support base plate 201, a column body 202, and a reinforcing rib 203, wherein the reinforcing rib 203 is connected to the support base plate 201 and the column body 202.

[0065] Specifically, in this embodiment, the column 202 is located at the center of the supporting base plate 201. To further enhance the structural strength and torsional resistance of the connection between the column 202 and the supporting base plate 201, several reinforcing ribs 203 are used for reinforcement: 4-6 triangular reinforcing ribs are evenly distributed along the circumference of the column 202, with one right-angle side fully welded to the outer wall of the column 202 and the other right-angle side fully welded to the upper surface of the supporting base plate 201. The welds are continuous fillet welds. The included angle between adjacent ribs is consistent (e.g., 4 ribs are distributed at 90 degrees, and 6 ribs are distributed at 60 degrees), forming a symmetrical and uniform reinforcement structure.

[0066] In a preferred embodiment, the column 202 is a cylindrical column or a square column.

[0067] Specifically, the column 202 can be flexibly selected according to the type of electrolytic cell, load-bearing requirements and installation scenario, and can be adapted to the reinforcing structure of the reinforcing rib 203 of the supporting base plate 201 to ensure the overall support stability.

[0068] In a preferred embodiment, the number of support columns 200 is at least three.

[0069] Specifically, there are at least three support columns 200. This design not only conforms to the geometric principle of "three points determine a plane", which can ensure that the bottom of the electrolytic cell is stably attached to the support surface, but also can be flexibly adapted to the load-bearing requirements of electrolytic cells of different specifications by increasing the number of columns. At the same time, it works in synergy with the movable structure 300 and the column structure 202 reinforced by the reinforcing ribs 203 to ensure the stability and safety of the overall support system.

[0070] From a basic support perspective, three support columns 200 are the minimum number required for stable placement of the electrolytic cell. With three support columns 200, they can be radially adjusted along the base plate 100 to a triangular distribution using the movable structure 300. The stable plane formed by the three support points effectively counteracts the vertical load generated by the electrolytic cell's own weight, while also preventing center of gravity shift due to insufficient support points. The triangular layout of the three support columns 200 also distributes the offset load evenly, preventing the electrolytic cell from tilting. In practical applications, the configuration of three support columns 200 is particularly suitable for small experimental electrolytic cells.

[0071] When the size of the electrolytic cell increases, such as an industrial-grade alkaline electrolytic cell, the number of support columns 200 can be increased to 4-6. In this case, the support columns 200 are still symmetrically distributed with the center of the base plate 100 as the origin (e.g., 4 in a rectangular distribution, 6 in a regular hexagonal distribution). The advantages of the multi-support column 200 design are twofold: First, it disperses the load. The force on a single support column 200 can be reduced from "total weight / 3" when there are 3 columns to "total weight / 6". Combined with the reinforcing structure of the column body 202 with reinforcing ribs 203, it can prevent the support column 200 from deforming at the root due to excessive local load. Second, it improves anti-interference capability. When there is vibration or lateral force generated during electrolytic cell assembly, more support columns 200 can form multi-point constraints, keeping the amplitude of the electrolytic cell within 0.05mm, far lower than the 0.1mm amplitude when there are 3 support columns 200, ensuring stable electrode spacing.

[0072] As a preferred embodiment, the base plate 100 is also provided with a number of hooks 101 for moving the tooling base.

[0073] Specifically, in this embodiment, the number of hooks 101 needs to be determined according to the size of the base plate 100 and the overall load-bearing weight. For example, when the base plate 100 has a size of 2000mm×1500mm (suitable for small electrolytic cells), the number of hooks 101 is set to 4, which are symmetrically distributed at the four corners of the base plate 100 and maintain a distance of 150-200mm from the edge of the base plate. This position will not occupy the radial movement trajectory of the support column 200 (when the support column 200 moves from the center to the edge, the minimum distance from the hook 101 is ≥300mm), and the base plate 100 can be lifted horizontally by four-point symmetrical hoisting to avoid deformation of the base plate due to uneven force. If the base plate 100 is enlarged to 4000mm×3000mm (to fit ultra-large electrolytic cells), then in addition to the four corner hooks 101, two more hooks 101 need to be added at the midpoint of the long side of the base plate to form a "6-point lifting" structure. At this time, the force of the six hooks 101 can be evenly distributed, and the load of a single hook 101 is reduced from "total weight / 4" at four points to "total weight / 6", reducing the stress load at the connection between the hook 101 and the base plate.

[0074] As a preferred embodiment, the base plate 100 is also provided with a horizontal height adjustment structure 102 for adjusting the horizontal height of the base plate 100.

[0075] Specifically, in this embodiment, the horizontal height adjustment structure 102 is used to precisely adjust the overall horizontal height of the base plate 100 to ensure that the horizontal error of the bottom support surface after the electrolytic cell is installed is ≤0.05mm / m. This structure needs to work in conjunction with the load-bearing strength of the base plate 100 and the height adjustment function of the support column 200, while avoiding the movement trajectory of the T-slot and avoiding interference with the position adjustment of the support column 200.

[0076] In a preferred embodiment, the horizontal height adjustment structure 102 includes: an adjustment bolt 1021 and a horizontal adjustment threaded hole 1022. The horizontal adjustment threaded hole 1022 is disposed on the base plate 100, and the adjustment bolt 1021 is connected to the horizontal adjustment threaded hole 1022.

[0077] Specifically, in this embodiment, the horizontal height adjustment structure 102 adopts a "spiral top support" design, with a total of 4 sets, corresponding to the four corners of the base plate 100 (offset from the position of the hook 101). Each set of structures includes an adjustment bolt 1021 and a horizontal adjustment threaded hole 1022: by turning the adjustment bolt 1021, it moves up and down in the horizontal adjustment threaded hole 1022, thereby adjusting the height of the base plate 100.

[0078] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0079] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0080] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
