Description

Technical Field

[0001] This invention relates to the field of electrolytic cell diaphragm technology, specifically to an adjustable pressure plate fixing structure for an electrolytic cell diaphragm. Background Technology

[0002] In the electrolysis industry, the diaphragm is a core component in the electrolytic cell that separates the anode and cathode regions, prevents reactants from mixing directly, and allows ions to pass through. The stability and accuracy of its installation and fixing directly affect the electrolysis reaction efficiency, product purity, and equipment operation safety. At present, the diaphragm of the electrolytic cell is mostly fixed by the traditional pressure plate structure, which is pressed on the outside of the diaphragm by bolts or welding to achieve the positioning of the diaphragm. Traditional pressure plates are mostly one-piece fixed designs, lacking flexible adjustment mechanisms. During installation, it is difficult to accurately adjust the pressing position and stress intensity of the pressure plate according to the actual size deviation of the diaphragm or assembly requirements. This can easily lead to uneven stress on the diaphragm, causing problems such as diaphragm deformation, damage, or poor sealing. Consequently, it can cause ion transport obstruction, increased energy consumption, and even safety hazards such as electrolyte leakage during electrolysis. On the other hand, the disassembly and assembly process of traditional structures is complex, requiring the use of special tools to remove bolts or cut welding points one by one. This is not only cumbersome and time-consuming, but may also cause secondary damage to components such as the diaphragm and electrolytic cell shell during disassembly and assembly, seriously affecting the maintenance efficiency and service life of the equipment. In addition, although some improved pressure plate structures attempt to add adjustment functions, the frictional resistance during adjustment is large, the positioning accuracy is insufficient, and there is a lack of convenient disassembly mechanisms. They still cannot meet the core requirements of modern electrolysis processes for diaphragm fixing structures: "efficient commissioning, rapid maintenance, and stable reliability."

[0003] Therefore, an adjustable pressure plate fixing structure for the diaphragm of an electrolytic cell is proposed to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable pressure plate fixing structure for a diaphragm in an electrolytic cell, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An adjustable pressure plate fixing structure for a diaphragm in an electrolytic cell includes an electrolytic cell shell, a diaphragm body installed inside the electrolytic cell shell, a pressure plate body disposed on the outside of the diaphragm body, and a convenient adjustment mechanism disposed between the diaphragm body and the pressure plate body. The convenient debugging mechanism includes a rotating plate with a moving groove inside. A connecting column is fixedly connected to the outside of the pressure plate. A sliding groove and a snap-fit ​​plate are fixedly connected to the outside of the connecting column. A limit groove is opened in the inner wall of the sliding groove. A limit plate is fixedly connected to the outside of the snap-fit ​​plate. A rotating groove is opened inside the snap-fit ​​plate, and a ball is rotatably snapped inside the rotating groove.

[0006] As a further optimization of the present invention, the connecting column is provided with a quick disassembly mechanism, the quick disassembly mechanism includes a hidden groove, a nylon rod is movably engaged inside the hidden groove, an extension plate is fixedly connected to the top of the nylon rod, and a compression spring is sleeved on the nylon rod.

[0007] As a further optimization of the present invention, the following features are provided: a connector is provided on the outer side of the operating plate, a cover plate is installed on the top of the electrolytic cell shell, and guide columns are provided on the outer side of the electrolytic cell shell, with the guide columns symmetrically distributed on the outer side of the electrolytic cell shell.

[0008] As a further optimization of the present invention, the pressure plate is symmetrically distributed on the outside of the diaphragm body, and the diaphragm body is evenly distributed inside the electrolytic cell shell, and the operating plate is installed on the inner wall of the electrolytic cell shell through a connector.

[0009] As a further optimization of the present invention, the connecting columns are symmetrically distributed on the outside of the pressure plate body, and the end of the connecting column away from the pressure plate body is slidably connected to the inside of the moving groove.

[0010] As a further optimization of the present invention, the sliding groove is adapted to the snap-fit ​​plate, and the limiting groove is symmetrically distributed on the inner wall of the sliding groove.

[0011] As a further optimization of the present invention, the sliding groove is adapted to the snap-fit ​​plate, and the limiting groove is symmetrically distributed on the inner wall of the sliding groove.

[0012] As a further optimization of the present invention, the balls are evenly distributed inside the rotating groove and are tightly attached to the inner wall of the sliding groove.

[0013] As a further optimization of the present invention, the hidden groove is formed inside the connecting column, and the hidden groove is symmetrically distributed inside the connecting column.

[0014] As a further optimization of the present invention, the nylon rods are symmetrically distributed inside the hidden groove, the extension plate is movably connected inside the hidden groove, and the extension plate is closely attached to the outside of the operating plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the sliding cooperation between the moving groove of the rotating plate and the connecting column, combined with the rolling action of the ball, makes the position adjustment of the pressure plate more flexible. The matching between the limiting plate and the limiting groove can ensure stable positioning, greatly reducing the difficulty of diaphragm installation and debugging and improving the overall operating efficiency.

[0016] 2. In this invention, the nylon rod inside the connecting column and the compression spring work together to achieve quick engagement or disengagement of the connecting column and the operating plate without the need for complicated tools. This effectively shortens the disassembly and assembly time of the pressure plate and diaphragm, making subsequent maintenance and replacement work more efficient and convenient.

[0017] 3. In this invention, the symmetrical distribution of the pressure plates adapts to the internal layout of the electrolytic cell, ensuring uniform stress on the diaphragm and reducing electrolysis failures caused by loose pressure plates; the setting of the flow guide column meets the flow requirements of the electrolytic medium, and the fixing method of the operating plate is highly compatible with the outer shell of the electrolytic cell, ensuring both the stability and reliability of the electrolysis process and meeting the actual electrolysis process application requirements.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] Please see Figures 1-9 The present invention provides a technical solution: An adjustable pressure plate fixing structure for a diaphragm in an electrolytic cell includes an electrolytic cell shell 1, a diaphragm body 2 installed inside the electrolytic cell shell 1, a pressure plate body 3 arranged on the outside of the diaphragm body 2, and a convenient adjustment mechanism 4 arranged between the diaphragm body 2 and the pressure plate body 3. The convenient adjustment mechanism 4 includes a rotating plate 41, with a moving groove 42 inside the rotating plate 41. A connecting column 43 is fixedly connected to the outside of the pressure plate body 3. A sliding groove 44 and a snap-fit ​​plate 45 are fixedly connected to the outside of the connecting column 43. A limit groove 441 is opened in the inner wall of the sliding groove 44. A limit plate 451 is fixedly connected to the outside of the snap-fit ​​plate 45. A rotating groove 452 is opened inside the snap-fit ​​plate 45. A ball bearing 453 is rotatably snapped inside the rotating groove 452.

[0023] It should be noted that: a connector 411 is provided on the outer side of the operating plate 41; a cover plate 11 is installed on the top of the electrolytic cell shell 1; guide columns 12 are provided on the outer side of the electrolytic cell shell 1, and the guide columns 12 are symmetrically distributed on the outer side of the electrolytic cell shell 1; pressure plates 3 are symmetrically distributed on the outer side of the diaphragm body 2, and the diaphragm body 2 is evenly distributed inside the electrolytic cell shell 1; the operating plate 41 is installed on the inner wall of the electrolytic cell shell 1 through the connector 411; connecting columns 43 are symmetrically distributed on the outer side of the pressure plates 3, and the end of the connecting column 43 away from the pressure plates 3 is slidably connected. Inside the moving groove 42, connecting posts 43 are symmetrically distributed inside the moving groove 42 and outside the pressure plate body 3. The end of the connecting post 43 away from the pressure plate body 3 is slidably connected inside the moving groove 42. The connecting posts 43 are symmetrically distributed inside the moving groove 42. The limiting plate 451 is symmetrically distributed outside the snap-fit ​​plate 45 and is adapted to the limiting groove 441. The limiting plate 451 is made of rubber. The balls 453 are evenly distributed inside the rotating groove 452 and are tightly attached to the inner wall of the sliding groove 44.

[0024] Furthermore, the outer shell 1 of the electrolytic cell serves as the installation foundation and protective carrier of the entire structure. The diaphragm body 2 is evenly arranged inside it, and the pressure plate body 3 is symmetrically arranged on the outer side of the diaphragm body 2. The pressing action of the pressure plate body 3 ensures that the diaphragm body 2 maintains a flat and stable posture during the electrolysis process, and avoids the impact of displacement on the electrolysis effect.

[0025] Specifically: A cover plate 11 is installed on the top of the electrolytic cell shell 1 to achieve sealing protection inside the cell. The symmetrically distributed guide columns 12 on the outside provide a channel for the flow of the electrolytic medium, ensuring the smooth operation of the electrolysis process. A convenient adjustment mechanism 4 is provided between the diaphragm body 2 and the pressure plate body 3. This mechanism includes a rotating plate 41 fixed to the inner wall of the electrolytic cell shell 1 by a connector 411. A moving groove 42 is opened inside the rotating plate 41. A connecting column 43 is symmetrically fixedly connected to the outside of the pressure plate body 3. The end of the connecting column 43 away from the pressure plate body 3 is slidably connected to the inside of the moving groove 42, forming the basic sliding structure for adjusting the pressure plate body 3.

[0026] Meanwhile, the outer side of the connecting column 43 is fixedly connected with a sliding groove 44 and a snap-fit ​​plate 45 that are compatible with each other. The inner wall of the sliding groove 44 is symmetrically provided with a limiting groove 441. The outer side of the snap-fit ​​plate 45 is correspondingly fixedly connected with a rubber limiting plate 451. The limiting plate 451 and the limiting groove 441 are adapted to achieve positioning constraint. At the same time, the inside of the snap-fit ​​plate 45 is evenly provided with a rotating groove 452. The rotating groove 452 is rotatably snapped with a ball 453 that is close to the inner wall of the sliding groove 44 to reduce the frictional resistance during the adjustment process.

[0027] As a further implementation of this solution, the connecting column 43 is provided with a quick disassembly mechanism 5. The quick disassembly mechanism 5 includes a hidden groove 51, a nylon rod 52 is movably engaged inside the hidden groove 51, an extension plate 53 is fixedly connected to the top of the nylon rod 52, and a compression spring 54 is sleeved on the nylon rod 52.

[0028] It should be noted that: the hidden groove 51 is opened inside the connecting column 43, and the hidden groove 51 is symmetrically distributed inside the connecting column 43; the nylon rod 52 is symmetrically distributed inside the hidden groove 51; the extension plate 53 is movably connected inside the hidden groove 51, and the extension plate 53 is closely attached to the outside of the operating plate 41.

[0029] Furthermore, the connecting column 43 is also equipped with a quick disassembly mechanism 5. This mechanism includes hidden grooves 51 symmetrically opened inside the connecting column 43. A nylon rod 52 is movably engaged in the hidden groove 51. An extension plate 53 is fixedly connected to the top of the nylon rod 52, and a compression spring 54 is sleeved on the nylon rod 52. The extension plate 53 is movably connected in the hidden groove 51 and can be closely attached to the outside of the operating plate 41. The quick engagement and disengagement function is realized through the elastic structure.

[0030] Work process: The outer shell 1 of the electrolytic cell serves as the installation carrier. The diaphragm body 2 installed inside it is pressed and positioned by the pressure plates 3 symmetrically distributed on the outside. The rotating plate 41 is fixed to the inner wall of the outer shell 1 of the electrolytic cell through the connector 411. The cover plate 11 on the top of the outer shell 1 of the electrolytic cell plays a sealing and protective role. The guide columns 12 symmetrically distributed on the outside ensure smooth flow of the electrolytic medium. When the convenient adjustment mechanism 4 is working, the pressure plate body 3 forms a sliding fit with the moving groove 42 of the rotating plate 41 through the symmetrically distributed connecting columns 43 on the outside. The connecting columns 43 can move along the extension direction of the moving groove 42 to adjust the distance between the pressure plate body 3 and the diaphragm body 2. The snap-fit ​​plate 45 on the outside of the connecting column 43 and the sliding groove 44 are mutually adapted. The rubber limiting plate 451 on the outside of the snap-fit ​​plate 45 is embedded in the limiting groove 441 on the inner wall of the sliding groove 44 to form a positioning constraint. At the same time, the ball 453 in the rotating groove 452 inside the snap-fit ​​plate 45 rolls tightly against the inner wall of the sliding groove 44, converting sliding friction into rolling friction to reduce adjustment resistance. When the quick disassembly mechanism 5 is used for disassembly and assembly, the extension plate 53 is pressed into the hidden groove 51. The extension plate 53 drives the nylon rod 52 to compress the compression spring 54 on the outside and retract into the hidden groove 51, releasing the clamping limit on the operating plate 41. At this time, the connecting column 43 can be pulled out from the moving groove 42 to complete the disassembly. When assembling, the connecting column 43 is inserted into the moving groove 42 and the extension plate 53 is released. The compression spring 54 elastically returns and pushes the nylon rod 52 to reset, so that the extension plate 53 extends out of the hidden groove 51 and is tightly attached to the outside of the operating plate 41 to form a limit. With the matching structure of the snap-fit ​​plate 45 and the sliding groove 44, quick fixation is completed.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
