Description

Technical Field

[0001] This utility model relates to the field of sealing structure technology, specifically to a gas-filled anode groove sealing structure on both sides. Background Technology

[0002] In the electrolysis industry, the anode cell is a key piece of equipment, and the stability and reliability of its sealing structure directly affect the efficiency and safety of the electrolysis process. Traditional anode cell sealing structures mostly employ lip-type sealing strips. While this sealing method can meet sealing requirements to a certain extent, it presents a series of significant problems during application.

[0003] First, the lip seal requires extremely high manufacturing precision for the anode groove. Strict dimensional tolerances must be controlled during the anode groove's processing to ensure a tight fit between the lip seal and the anode groove, thus achieving a good sealing effect. However, this high precision requirement undoubtedly increases the manufacturing cost and difficulty of the anode groove.

[0004] Secondly, the lip seal requires strict precision in the installation of the cathode roller and anode groove. During installation, the relative positions of the cathode roller and anode groove must be accurate to avoid seal failure due to installation deviations. This requirement not only increases the complexity of the installation work but may also lead to human error during the installation process.

[0005] Furthermore, the lip seal can easily cause uneven stress during the rotation of the cathode roller. Due to the structural characteristics of the lip seal, it may generate uneven friction when in contact with the cathode roller, resulting in an unbalanced force on the cathode roller during rotation, which affects the stability and efficiency of the electrolysis process.

[0006] Therefore, in view of this, the existing structure was studied and improved, and a gas-filled anode tank sealing structure on both sides was proposed. Utility Model Content

[0007] The technical problem this invention aims to solve is the high precision requirements, uneven stress distribution, and high operating resistance inherent in existing sealing structures on both sides of the anode tank. Traditional lip-shaped sealing strip designs not only require high precision for both the anode tank and the cathode roller, but also are prone to uneven stress distribution during long-term operation, leading to seal failure and equipment wear. Furthermore, the high coefficient of friction increases operating resistance and reduces the efficiency of the electrolysis process.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an inflatable anode groove sealing structure on both sides, including an anode support, a sealing strip base and an anode plate are provided on the top of the anode support, and the anode plate is provided on one side of the sealing strip base. A pad, a polytetrafluoroethylene (PTFE) strip and a pressure plate are sequentially provided on the top of the sealing strip base. A fixing assembly for fixing the sealing strip base, the pad, the PTFE strip and the pressure plate is provided on the anode support. An inflatable sealing strip is fixedly provided on the sealing strip base, and a PTFE strip covers the top of the inflatable sealing strip. A cathode roller edge ring is attached to the PTFE strip, and a rubber ring and a cathode roller are provided on the cathode roller edge ring.

[0009] As a further embodiment of this utility model: the fixing component includes a screw fixedly installed on the top of the anode support, and the sealing strip base, gasket, polytetrafluoroethylene strip, and pressure plate are all sleeved on the screw and fixed by nuts.

[0010] As a further aspect of this utility model, the inflatable sealing strip is made of a material with high elasticity and wear resistance.

[0011] As a further embodiment of this invention, the surface of the polytetrafluoroethylene strip is provided with an anti-slip texture.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. Reduced manufacturing and installation costs: The design of the inflatable sealing strip requires relatively lower manufacturing precision for the anode groove and cathode roller, which greatly simplifies the production process and reduces manufacturing costs. Simultaneously, the installation process does not require excessively high-precision alignment, reducing installation difficulty and time, further lowering installation costs.

[0014] 2. Improved sealing performance: The inflatable sealing strip adjusts its tightness through inflation, better adapting to sealing requirements under different working conditions. This dynamic adjustment capability ensures the stability and durability of the sealing effect, effectively preventing electrolyte leakage and improving the safety and efficiency of the electrolysis process.

[0015] 3. Optimized stress distribution: The inflatable sealing strip provides a more uniform stress distribution during the rotation of the cathode roller, avoiding the uneven stress distribution that may occur with traditional lip sealing strips. This helps reduce wear on the cathode roller, extend the service life of the equipment, and improve the stability and continuity of the electrolysis process.

[0016] 4. Reduced operating resistance: The application of new materials such as PTFE tape results in a lower coefficient of friction in the newly invented sealing structure, thereby reducing the operating resistance during the rotation of the cathode roller. This not only reduces energy consumption but also improves the overall efficiency of the electrolysis process.

[0017] 5. Enhanced adaptability: The inflatable sealing strip design allows it to flexibly adapt to anode tanks and cathode rollers of different sizes, improving the equipment's versatility and flexibility. This is of great significance for the diversified production needs of the electrolysis industry. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 This embodiment provides a gas-filled anode groove sealing structure, specifically including an anode support 12. The anode support 12 serves as the supporting component of the entire sealing structure, ensuring its stability and reliability. A sealing strip base 1 and an anode plate 11 are provided on the top of the anode support 12, with the anode plate 11 positioned on one side of the sealing strip base 1. This layout ensures the normal operation of the anode plate 11 and provides an installation foundation for the sealing structure.

[0024] At the top of the sealing strip base 1, a gasket 2, a PTFE strip 3, and a pressure plate 4 are arranged in sequence. The gasket 2 is designed to keep the PTFE strip 3 horizontal during operation, ensuring a good seal. The PTFE strip 3 has a low coefficient of friction and good wear resistance, effectively reducing the running resistance during the rotation of the cathode roller. The pressure plate 4 is used to fix the PTFE strip 3, preventing it from shifting during operation.

[0025] To ensure the secure installation of the sealing strip base 1, gasket 2, PTFE strip 3, and pressure plate 4, a fixing assembly is provided on the anode support 12. In this embodiment, the fixing assembly includes a screw 6 fixedly mounted on the top of the anode support 12, and the sealing strip base 1, gasket 2, PTFE strip 3, and pressure plate 4 are all sleeved on the screw 6 and secured with nuts 5. This fixing method is simple, reliable, and easy to install and disassemble.

[0026] An inflatable sealing strip 7 is fixedly installed on the sealing strip base 1. The inflatable sealing strip 7 is made of a material with high elasticity and wear resistance, such as rubber or silicone. This material selection ensures both the sealing effect of the inflatable sealing strip 7 and extends its service life. A polytetrafluoroethylene (PTFE) strip 3 covers the top of the inflatable sealing strip 7. When the inflatable sealing strip 7 is inflated, it protrudes upwards, pressing against the PTFE strip 3, making it tightly adhere to the cathode roller edge ring 8, thereby achieving a sealing effect.

[0027] A rubber ring 9 and a cathode roller 10 are provided on the cathode roller side ring 8. The rubber ring 9 further enhances the sealing effect and prevents electrolyte leakage. During rotation, the cathode roller 10 comes into contact with the inflatable sealing strip 7 and the PTFE belt 3. Since the PTFE belt 3 has a low coefficient of friction, it can reduce operating resistance and improve the efficiency of the electrolysis process.

[0028] In this embodiment, the surface of the PTFE tape 3 is provided with an anti-slip texture. The anti-slip texture increases the friction between the PTFE tape 3 and the cathode roller edge ring 8, preventing slippage during operation and thus ensuring the stability and durability of the sealing effect.

[0029] In practical use, the tightness of the inflatable sealing strip 7 can be controlled by adjusting the inflation pressure to meet the sealing requirements under different working conditions. This dynamic adjustment capability ensures the stability and durability of the sealing effect, effectively prevents electrolyte leakage, and improves the safety and efficiency of the electrolysis process.

[0030] In summary, the inflatable anode tank side sealing structure provided in this embodiment effectively solves the technical problems of high precision requirements, uneven stress distribution, and high operating resistance existing in current anode tank side sealing structures by adopting novel materials such as inflatable sealing strips 7 and polytetrafluoroethylene (PTFE) tape 3, and a unique fixing component design. This sealing structure has advantages such as low manufacturing and installation costs, good sealing performance, uniform stress distribution, low operating resistance, and strong adaptability, making it suitable for various anode tank sealing needs in the electrolysis industry.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
