Description

Technical Field

[0001] The invention relates to the technical field of electrolytic equipment manufacturing, in particular to a high-precision integrated electrolytic chamber based on concave-convex positioning holes. Background Art

[0002] The existing electrolytic chamber processing technology mostly adopts traditional assembly and welding methods, such as direct bonding, ordinary bolt fixing or conventional welding. Although these processes can realize the assembly of electrolytic chambers, they expose the following technical defects and deficiencies in actual applications:

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

[0004] Traditional assembly processes rely on manual or simple positioning devices, which makes it difficult to ensure precise alignment between components, resulting in large assembly errors. This error will directly affect the sealing performance and overall strength of the chamber, reducing the long-term reliability of the device. Especially when it comes to chambers with complex geometric structures, the error accumulation problem is more prominent.

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

[0006] The common welding process currently used has high requirements on the temperature, pressure and operating conditions of the welding parts. If you are not careful, welding defects such as weld porosity, cracks or deformation will occur. Welding defects not only affect the sealing performance of the electrolytic chamber, but may also cause electrolyte leakage or uneven internal electrolytic environment. In addition, the consistency of welding quality is difficult to control, which increases the cost of finished product inspection and rework.

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

[0008] The traditional process is complicated and requires repeated positioning and adjustment. It also takes a long time to process and is difficult to meet the needs of industrial mass production. This inefficient production method seriously restricts the ability to respond quickly to market demand.

[0009] (4) Electrolysis efficiency and equipment performance are limited

[0010] Due to insufficient positioning and welding accuracy, the actual effective electrolysis area of ​​the electrolysis chamber is difficult to maximize, affecting the uniformity of gas-liquid distribution during the electrolysis process, resulting in reduced electrolysis efficiency. At the same time, structural unevenness may cause hot spots in local electrochemical reactions, further shortening the service life of the equipment.

[0011] (5) Insufficient reliability and product quality

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

[0013] Therefore, providing an innovative process and assembly method that can solve the above problems can not only improve the positioning accuracy and welding quality of the chamber components, but also significantly improve the processing efficiency and meet the needs of industrial production. This is a technical problem that technical personnel in this field urgently need to solve. In addition, optimizing the structure of the electrolysis chamber to increase the effective electrolysis area and electrolysis efficiency has important practical significance. Summary of the invention

[0014] The purpose of the present invention is to provide an integrated electrolysis chamber based on concave-convex positioning holes to solve the problems of low positioning accuracy, poor welding reliability, low processing efficiency and insufficient electrolysis efficiency in the prior art. The present invention realizes high-precision and high-reliability chamber assembly by introducing precise positioning and hot-melt welding processes, improves processing efficiency and product quality, and maximizes the effective electrolysis area of ​​the electrolysis chamber, thereby significantly improving the electrolysis efficiency and meeting the needs of industrial production.

[0015] To achieve the above object, the present invention adopts the following technical solution:

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

[0017] Wherein, the electrode plate includes a first electrode plate and a second electrode plate, the nipple includes a first nipple and a second nipple, and the electrode includes a first electrode and a second electrode;

[0018] The electrolysis chamber comprises, from left to right, a first electrode plate, a first nipple, a first electrode, a diaphragm, a second electrode, a second nipple, and a second electrode plate;

[0019] The first electrode plate is provided with a large trapezoidal groove, and the second electrode plate is provided with a large trapezoidal protrusion matching the large trapezoidal groove. The first electrode plate and the second electrode plate are fixed together by the large trapezoidal groove and the large trapezoidal protrusion to form an electrolysis chamber.

[0020] In the present invention, the main body of the electrolysis chamber adopts an innovative V-shaped cavity structure. By optimizing the design of the cavity geometry, the fluid can flow evenly 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 areas, and significantly improving the efficiency and stability of the electrolysis reaction.

[0021] The nipple used in the present invention is part of the internal design of the V-shaped cavity, and is mainly used to guide the flow of fluid in the electrolysis chamber and optimize the fluid path. Its convex structure can effectively disturb the fluid, promote the uniform distribution of the fluid, and avoid the occurrence of uneven flow field or retention. At the same time, the nipple also plays a role in supporting the diaphragm and the electrode, ensuring its stability during the working process.

[0022] The electrodes in the present invention are made of highly conductive and corrosion-resistant materials, which can ensure long-term operating stability and efficiency.

[0023] The size of the large trapezoidal protrusion is exactly the same as that of the large trapezoidal groove, which can ensure the air tightness and liquid tightness of the electrolytic chamber and prevent fluid leakage. The trapezoidal groove fits perfectly with the large trapezoidal protrusion, which is used to connect the left and right plates and fix the position, further enhancing the sealing effect.

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

[0025] Furthermore, the first electrode plate and the second electrode plate are fixed together by hot melt adhesive.

[0026] Furthermore, the second pole plate is also provided with a small trapezoidal protrusion, and the first pole plate is provided with a small trapezoidal groove matching the small trapezoidal protrusion.

[0027] Furthermore, the small trapezoidal protrusions are made of hot-melt material; when the first electrode plate and the second electrode plate are welded, the small trapezoidal protrusions melt to form liquid to fix the various components, and the molten liquid enters the large trapezoidal grooves and the gaps of the large trapezoidal protrusions, thereby enhancing the structural stability and sealing of the electrolytic chamber.

[0028] The small trapezoidal protrusions of the present invention melt during welding and are used to firmly fix the various components together. The molten liquid enters the gap between the trapezoidal grooves and the trapezoidal protrusions to ensure the overall structural stability and sealing of the electrolytic chamber.

[0029] Furthermore, the side surfaces of the electrode plates are provided with a liquid inlet and a liquid outlet.

[0030] In the present invention, the fluid enters the V-shaped cavity from the liquid inlet, and the uniform distribution of the fluid is achieved by designing an optimized flow channel. The liquid generated after electrolysis flows out through the liquid outlet to avoid fluid retention and ensure continuous reaction.

[0031] The above scheme of the present invention can overcome the problems of uneven flow field, poor gas-liquid separation effect and fluid stagnation in the existing electrolysis chamber design. The present invention is an electrolysis chamber based on a V-shaped cavity structure, which realizes the uniform distribution of the flow field in the electrolytic cell through a unique structural design and assembly method, and significantly improves the electrolysis efficiency. In the present invention, the electrode plate is a key component, and the surface is distributed with nipples to increase the contact area with the electrolyte. The electrode is connected to the electrode plate for introducing current. The large trapezoidal protrusions and the small trapezoidal protrusions are respectively matched with the corresponding trapezoidal grooves through concave and convex positioning to achieve accurate positioning and stable connection of the components. The diaphragm is located between the positive and negative electrodes to separate the electrolyte in different areas, ensuring that the electrolysis reaction is carried out efficiently and stably.

[0032] The beneficial effects of the present invention are:

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

[0034] The present invention can achieve rapid and accurate alignment during the assembly of electrolysis chamber components by designing concave-convex positioning holes, significantly reduce assembly errors, and ensure the sealing and stability of the overall structure.

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

[0036] The present invention adopts a hot-melt welding process to form an electrolytic chamber, which can effectively avoid defects such as pores and cracks in traditional welding, and the welding quality is uniform and reliable, thereby improving the strength and service life of the electrolytic chamber.

[0037] (3) Improved processing efficiency

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

[0039] (4) Improved electrolysis efficiency

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

[0041] (5) High quality and industrial adaptability

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

[0043] In summary, the present invention not only solves the main defects in the prior art, but also achieves a comprehensive improvement in assembly accuracy, welding quality and electrolysis efficiency through innovative processing methods and structural designs, which is of great significance to the production and application of electrolysis equipment.
