Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to an electrocoagulation anode connection structure. Background Technology

[0002] Electrocoagulation technology is widely used in the field of water treatment. Its core lies in generating flocculents that can remove pollutants through electrode reactions. As a key component in the electrocoagulation system, the performance of the anode directly affects the efficiency and stability of the entire system.

[0003] In existing technologies, the connection structure of the anode typically needs to meet two important requirements: First, the anode must have a good seal with the housing to prevent leakage of the treated liquid and the entry of external contaminants. Insufficient sealing performance will lead to reduced electrolysis efficiency and may cause equipment damage or unstable operation. Second, the anode's position within the housing must be stable. Unstable position will result in uneven electric field distribution, affecting flocculation. Loosening or displacement of the anode may cause short circuits or equipment damage, thereby increasing maintenance costs and downtime.

[0004] Therefore, it is necessary to improve the reliability and efficiency of the electrocoagulation system by improving the connection mechanism. Utility Model Content

[0005] In view of at least one of the above technical problems, the present invention provides an electrocoagulation anode connection structure, which improves the reliability of the electrocoagulation anode by adopting improvements in the sealing structure and positioning structure.

[0006] According to a first aspect of the present invention, an electrocoagulation anode connection structure is provided, comprising: The housing has an opening at one end, and an anode is installed inside.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figures 1 to 5 The electrocoagulation anode connection structure shown includes: The housing 1 has an opening 11 at one end, and an anode 12 is installed inside. It should be noted that the housing 1 can be made of various materials, such as stainless steel, PVC, or other corrosion-resistant materials.

[0024] The end cap 21 mechanism 2 includes an end cap 21 connected to the opening 11, and a through hole 22 is provided in the center of the end cap 21.

[0025] Connecting rod 3 passes through through hole 22 and connects to anode 12. It should be noted that connecting rod 3 can be made of various materials, such as titanium alloy, aluminum, or other conductive and corrosion-resistant materials.

[0026] The sealing mechanism 4 includes a fixing member 41 that passes through the connecting rod 3 and is connected to the end cap 21, a locking member 42 that passes through the connecting rod 3 and is connected to the fixing member 41, and a sealing member 43 that passes through the connecting rod 3 and is installed between the fixing member 41 and the locking member 42. It should be noted that the sealing member 43 can be made of rubber, a metal with ductility and corrosion resistance, or other materials that can be used as a seal.

[0027] Positioning component 5, such as Figure 2 As shown, the anode 12, which extends into the interior of the housing 1, is connected to at least two support rods 51 facing the inner wall of the housing 1, with each support rod 51 being equidistant from the housing 1. It should be noted that the support rods 51 are evenly spaced according to their number, and each faces the inner wall of the housing 1 to provide support for the anode 12.

[0028] When the fixing member 41 and the locking member 42 are connected, the sealing member 43 is compressed and sealed. It should be noted that there are many ways to connect the fixing member 41 and the locking member 42, including threaded connection, snap-fit ​​connection, and other possible connection methods.

[0029] When installing the electrocoagulation anode connection structure of this utility model, first connect the connecting rod 3 to the anode 12, then place the anode 12 into the housing 1, pass the end cap 21 through the connecting rod 3 to connect the end cap 21 to the housing 1, then pass the fixing member 41 through the connecting rod 3 and fix it to the end cap 21, then pass the sealing member 43 and the locking member 42 through the connecting rod 3 and fix the locking member 42 to the connecting member. During connection, by adjusting the connection tightness of the fixing member 41 and the locking member 42, the sealing member 43 is compressed to form an effective seal, preventing any leakage of liquid or gas.

[0030] This invention achieves effective sealing and precise positioning of the anode 12 through a housing 1, an end cap 21 mechanism 2, a connecting rod 3, a positioning element 5, and a sealing mechanism 4. The housing 1 provides installation space for the anode 12 and is combined with the end cap 21. A through hole 22 in the center of the end cap 21 allows the connecting rod 3 to be securely connected to the anode 12. The positioning element 5 ensures the stable position of the anode 12 within the housing 1 through at least two support rods 51. The support rods 51 are designed to be equidistant from the inner wall of the housing 1 to ensure uniform electric field distribution in all directions during electrolysis. The connecting rod 3 is detachably connected to the fixing element 41 and the locking element 42 via threads or other means. The sealing mechanism 4 uses a sealing element 43 positioned between the fixing element 41 and the locking element 42. The connection between the fixing element 41 and the locking element 42 compresses the sealing element 43, thereby achieving effective sealing, enhancing the stability of the connection, and ensuring convenience for maintenance and replacement.

[0031] In traditional designs, fastener 41 typically lacks flexibility, making it difficult to quickly disassemble and reassemble during maintenance, and may lead to a decrease in sealing performance. To address this issue, such as... Figure 4 As shown, in some embodiments of this invention, the fastener 41 includes a fixing section 41a, one end of which is threadedly connected to the end cap 21, and a locking section 41b, the other end of which is threadedly connected to the locking member 42. The threaded connection design allows for precise adjustment of the tightness of the fixing section 41a and the locking section 41b during installation, thereby applying appropriate pressure during the compression of the seal 43 to ensure leak-free sealing performance. This not only improves the reliability of the seal but also simplifies the installation and disassembly process. Compared to traditional welding or adhesive fixing methods, the use of a threaded connection also reduces the complexity of assembly and maintenance, making component replacement or regular maintenance more convenient.

[0032] Most existing seals 43, such as simple circular gaskets, are prone to seal failure when exposed to pressure changes or vibrations, increasing the risk of liquid leakage and affecting system performance. In some embodiments of this invention, such as... Figure 2 , Figure 4As shown, the seal 43 is an annular structure with a large diameter in the middle and small diameters at both ends. One end of the seal 43 can extend between the fixing member 41 and the connecting plate, and the other end extends between the locking member 42 and the connecting rod 3. The annular structure allows the seal 43 to form a more stable sealing surface when compressed. The larger diameter in the middle provides additional compression protection, enabling the seal 43 to fit more tightly against the contact surfaces of the fixing member 41 and the locking member 42 under pressure, thus enhancing the sealing ability. The smaller diameters at both ends make it easier for the seal 43 to extend between the fixing member 41 and the connecting plate, and between the locking member 42 and the connecting rod 3, increasing the contact area between the seal 43 and the connecting rod 3 and further reducing the possibility of leakage. By enhancing the sealing performance, the seal 43 provides important support for the long-term stable operation of the electrocoagulation equipment, improving the economy and practicality of the entire water treatment process.

[0033] Existing sealing materials such as rubber and plastics, while possessing a certain degree of elasticity, are prone to aging and deformation in high-temperature, strong acid, or strong alkali environments, leading to seal failure. In some embodiments of this invention, the seal 43 is made of copper. Copper possesses excellent corrosion resistance and thermal conductivity, enabling it to maintain material stability in harsh chemical environments. Compared to traditional materials, copper exhibits less expansion and contraction under high-temperature and high-pressure conditions, reducing the likelihood of damage to the seal 43 under extreme operating conditions. The strength and hardness of copper ensure that the seal 43 maintains its sealing integrity under physiological stress and physical impact, thereby extending the service life of the entire system.

[0034] The connecting rod 3 faces problems of friction, corrosion, and electrical interference during long-term use, which may lead to a decrease in electrochemical efficiency or system failure. Existing connection methods often neglect the protection of the connecting rod 3, resulting in increased maintenance costs and a shortened service life. The connecting rod 3, installed inside the housing 1, is also fitted with heat-shrink tubing. The heat-shrink tubing has excellent insulation and protective properties, and after heating, it adheres to the surface of the connecting rod 3, forming a tight protective layer. This effectively prevents current leakage, reduces electrical interference, and ensures the stability of current transmission. The wear-resistant and corrosion-resistant properties of the heat-shrink tubing provide additional protection for the connecting rod 3, reducing the corrosive effects from the processed liquid and protecting it from external friction damage.

[0035] like Figure 5As shown, the end cap 21 is threadedly connected to the housing 1, and a sealing ring 23 is also provided between the end cap 21 and the housing 1. The threaded connection provides a stable mechanical bond, which can withstand greater force and pressure changes, ensuring the stable position of the end cap 21 over a long period of time. In contrast, traditional methods are prone to loosening or displacement due to vibration or impact. The threaded connection makes assembly and maintenance simpler and more controllable, improving the equipment's adaptability to environmental changes. The sealing ring 23 located between the end cap 21 and the housing 1 further ensures reliable sealing performance through elastic fit. The sealing ring 23 effectively prevents liquid leakage and the intrusion of external contaminants, maintaining the chemical stability and electrical insulation inside the equipment, which is crucial for the efficient operation of the electrocoagulation process.

[0036] In the electrocoagulation system, the support rod 51 not only serves to fix and stabilize the position of the anode 12, but also needs to operate stably and reliably in the chemical reaction environment for a long time. The support rod 51 is made of polypropylene. Polypropylene has excellent chemical corrosion resistance and can maintain its structural integrity in acidic and alkaline environments, which is crucial for long-term operation in the electrocoagulation system. The high strength and toughness of polypropylene ensure that the support rod 51 maintains a stable supporting effect even under external forces or vibrations, thus ensuring the precise positioning of the anode 12 in the electric field. Compared to traditional metal support rods 51, the use of polypropylene not only reduces the overall weight of the component, thereby reducing transportation and installation costs, but also reduces the impact on equipment load.

[0037] The support rod 51 is tightly attached to the inner wall of the housing 1. While this provides support, it limits flexibility and adjustment space, potentially leading to stress concentration due to thermal expansion or material deformation, ultimately affecting the system's operational stability. Figure 3 As shown, there is a gap between the support rod 51 and the housing 1. The support rod 51 and the housing 1 experience slight displacement due to temperature changes or system pressure fluctuations, which reduces deformation stress caused by expansion or contraction. The gap improves the structure's cushioning performance and seismic resistance, allowing the anode 12 to maintain a precise position under different operating conditions. By reducing direct contact, the gap enhances the independence of the housing 1 and the support rod 51, reduces frictional wear, and thus extends the component's service life.

[0038] Traditional support designs may employ simple straight lines, but their limited contact area with the inner wall of the housing 1 fails to adequately accommodate the complex shapes within the housing 1, leading to instability or inaccurate positioning. Therefore, a design reference is urgently needed. Figure 3The end shape of the support rod 51 is similar to that of the inner wall of the housing 1. By matching the shape of the housing 1, the support rod 51 can better resist mechanical stress and vibration from multiple directions. This greatly reduces the risk of displacement of the anode 12 due to uneven force during operation, improves the dynamic stability of the structure, and enables the entire system to maintain a reliable operating state in the face of environmental changes and dynamic working conditions.

[0039] In some embodiments of this invention, the connecting rod 3 is made of titanium. Titanium has excellent corrosion resistance, maintaining its shape and strength even in harsh chemical environments. This material property ensures that the connecting rod 3 can operate stably under highly corrosive and high-temperature conditions, supporting the efficient implementation of the electrocoagulation process. Titanium's high strength-to-weight ratio provides excellent mechanical properties, which not only helps reduce the overall weight of the equipment but also reduces the difficulty of installation and maintenance.
