Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrolytic equipment manufacturing, specifically to a high-precision integrated electrolytic cell based on concave-convex positioning holes. BACKGROUND

[0002] In existing electrolytic cell processing technology, traditional assembly and welding methods are often used, such as direct bonding, ordinary bolt fixation, or conventional welding. Although these processes can achieve the assembly of electrolytic cells, they expose the following technical defects and deficiencies in actual application:

[0003] (1) Low positioning accuracy and large assembly error

[0004] Traditional assembly processes rely on manual or simple positioning devices, making it difficult to ensure accurate alignment between components, resulting in large assembly errors. Such errors can directly affect the sealing performance and overall strength of the cell, reducing the long-term reliability of the device. Especially when it comes to cells with complex geometrical structures, error accumulation is even more prominent.

[0005] (2) Unstable welding process and poor quality consistency

[0006] The ordinary welding process currently used has high requirements for temperature, pressure, and operating conditions at the welding site. Any slight mistake can result in welding defects such as weld porosity, cracks, or deformation. Welding defects not only affect the sealing performance of the electrolytic cell, but also may cause electrolyte leakage or uneven internal electrolysis environment. In addition, the consistency of welding quality is difficult to control, increasing the cost of finished product inspection and rework.

[0007] (3) Low processing efficiency and difficulty in batch production

[0008] Traditional process steps are tedious, requiring multiple repeated positioning and adjustments, and the processing time is relatively long, making it difficult to meet the needs of industrialized batch production. This low-efficiency production method seriously restricts the rapid response capability of market demand.

[0009] (4) Limited electrolysis efficiency and device performance

[0010] Due to insufficient positioning and welding accuracy, the actual effective electrolysis area of the electrolytic cell is difficult to maximize, affecting the uniformity of gas-liquid distribution during the electrolysis process, resulting in reduced electrolysis efficiency. At the same time, uneven structure may cause local electrochemical reaction hot spots, further shortening the service life of the device.

[0011] (5) Insufficient reliability and product quality

[0012] The structural design and manufacturing method of the traditional process are relatively single, lack precise positioning and efficient assembly means, resulting in poor product quality consistency. In addition, the instability of the structure also makes it difficult to ensure the reliability of the equipment during long-term operation, and it is prone to failure.

[0013] Therefore, it is an urgent technical problem for those skilled in the art to provide an innovative process and assembly method that can solve the above problems, improve the positioning accuracy and welding quality of the cell components, significantly improve the processing efficiency, and meet the industrial production needs. In addition, by optimizing the electrolytic cell structure to improve the effective electrolysis area and electrolysis efficiency, it has important practical significance SUMMARY

[0014] The present application aims to solve the problems of low positioning accuracy, poor welding reliability, low processing efficiency and insufficient electrolysis efficiency in the prior art, and provides an integrated electrolytic cell based on concave-convex positioning holes. The present application introduces precise positioning and hot melt welding process to realize high-precision and high-reliability cell assembly, improve processing efficiency and product quality, maximize the effective electrolysis area of the electrolytic cell, thereby significantly improving the electrolysis efficiency and meeting the industrial production needs.

[0015] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0016] A high-precision integrated electrolytic cell based on concave-convex positioning holes, comprising a polar plate, a milk convex, an electrode and a diaphragm.

[0017] Among them, the polar plate includes a first polar plate and a second polar plate, the milk convex includes a first milk convex and a second milk convex, and the electrode includes a first electrode and a second electrode.

[0018] The electrolytic cell is sequentially arranged from left to right as the first polar plate, the first milk convex, the first electrode, the diaphragm, the second electrode, the second milk convex and the second polar plate.

[0019] The first polar plate is provided with a large trapezoidal groove, and the second polar plate is provided with a large trapezoidal protrusion matched with the large trapezoidal groove, and the first polar plate and the second polar plate are fixed to form an electrolytic cell through the combination of the large trapezoidal groove and the large trapezoidal protrusion.

[0020] In the present application, the electrolytic cell body adopts an innovative V-shaped cavity structure. Through the optimization design of the cavity geometry, the fluid flows uniformly along the V-shaped path during the electrolysis process, effectively reducing the flow resistance and flow field unevenness, while avoiding the formation of dead corners and stagnant zones, significantly improving the efficiency and stability of the electrolysis reaction.

[0021] The V-shaped protrusion is part of the internal design of the V-shaped cavity, mainly used for guiding fluid flow in the electrolysis chamber and optimizing the fluid path.

[0022] The electrode in the application is made of a material with high conductivity and corrosion resistance, which can ensure the stability and efficiency of long-term operation.

[0023] The size of the large trapezoidal protrusion is completely consistent with the large trapezoidal groove, which can ensure the air tightness and liquid tightness of the electrolysis chamber and prevent fluid leakage.

[0024] The diaphragm in the application is installed between the electrodes to separate the anode and cathode chambers, prevent product mixing (such as hydrogen and oxygen), but allow ions to pass through, maintain the normal progress of the electrolysis reaction.

[0025] Further, the first and second plates are fixed together by hot melt glue.

[0026] Further, the second plate is also provided with a small trapezoidal protrusion, and the first plate is provided with a small trapezoidal groove matched with the small trapezoidal protrusion.

[0027] Further, the small trapezoidal protrusion is made of hot melt material; when the first and second plates are welded, the small trapezoidal protrusion melts to form a liquid to fix the components, and the melted liquid enters the gap between the large trapezoidal groove and the large trapezoidal protrusion, thereby enhancing the structural stability and sealing of the electrolysis chamber.

[0028] The small trapezoidal protrusion in the application melts when welding, which is used to firmly fix the components together, and the melted liquid enters the gap between the trapezoidal groove and the trapezoidal protrusion, ensuring the overall structural stability and sealing of the electrolysis chamber.

[0029] Further, the side of the plate is provided with a liquid inlet and a liquid outlet.

[0030] In the application, the fluid enters the V-shaped cavity from the liquid inlet, and the uniform distribution of the fluid is realized through the design and optimization of the flow channel. The liquid produced after electrolysis flows out through the liquid outlet, avoiding fluid retention and ensuring continuous reaction.

[0031] The electrolytic cell of the present application can overcome the problems of uneven flow field, poor gas-liquid separation effect and fluid stagnation in the existing electrolytic cell design. The electrolytic cell based on V-shaped cavity structure realizes uniform distribution of flow field in the electrolytic cell through unique structural design and assembly method, significantly improving the electrolysis efficiency. In the present application, the surface of the electrode plate, as a key component, is distributed with bumps to increase the contact area with the electrolyte. The electrode is connected to the electrode plate for current introduction. The large and small trapezoidal protrusions are respectively matched with the corresponding trapezoidal grooves through concave-convex positioning to realize precise positioning and stable connection of the components. The diaphragm is located between the positive and negative electrodes to separate the electrolyte in different areas and ensure efficient and stable electrolysis reaction.

[0032] The present application has the following advantages:

[0033] (1) Precise positioning to improve assembly accuracy

[0034] The present application realizes rapid and accurate alignment during the assembly of electrolytic cell components through the design of concave-convex positioning holes, significantly reducing assembly errors and ensuring the sealing and stability of the overall structure.

[0035] (2) High reliability and superior welding quality

[0036] The present application uses hot melt welding process to form the electrolytic cell, which can effectively avoid defects such as pores and cracks in traditional welding, ensuring uniform and reliable welding quality and improving the strength and service life of the electrolytic cell.

[0037] (3) Improved processing efficiency

[0038] The introduction of concave-convex positioning holes simplifies the assembly process, reduces the dependence on manual adjustment, significantly shortens the processing time, improves the efficiency of batch production, and reduces production costs.

[0039] (4) Improved electrolysis efficiency

[0040] The optimized cell structure, combined with high-precision assembly and welding process, fully utilizes the effective electrolysis area, improves the uniformity of gas-liquid distribution during electrolysis, and significantly improves the electrolysis efficiency.

[0041] (5) High quality and industrial adaptability

[0042] Through precise positioning and efficient processing, the consistency and stability of the product are ensured, meeting the needs of industrial production and providing reliable protection for the upgrading and application of electrolytic equipment.

[0043] In summary, the present application not only solves the main defects in the prior art, but also realizes the overall improvement of assembly accuracy, welding quality and electrolysis efficiency through innovative processing methods and structural design, which has important significance for the production and application of electrolytic equipment.
