[0002] Circulating water treatment systems are widely used in industrial cooling, wastewater treatment, and other fields. The electrochemical reaction tank, as the core equipment, achieves functions such as sterilization, algae removal, and heavy metal removal through electrochemical oxidation / reduction reactions. The electrode plates, as the core components of the reaction, are susceptible to scale, organic matter buildup, and electrolysis byproduct deposition after long-term operation, requiring regular disassembly and cleaning to maintain treatment efficiency.

[0003] Traditional electrochemical reactor electrode installation methods are quite cumbersome, often using multiple sets of bolts and washers to fix the electrodes. Each installation and disassembly requires tightening and loosening one electrode at a time, resulting in a long disassembly and installation process, increasing labor and material costs, and also affecting the operation of the circulating water treatment system. Utility Model Content

[0004] To overcome the cumbersome installation methods of traditional electrochemical reaction tanks, which often use multiple sets of bolts and washers to fix the electrodes, requiring each electrode to be tightened and loosened individually for each installation and removal, resulting in lengthy disassembly and installation processes, increased labor and material costs, and impacting the continuous operation of circulating water treatment systems, this invention provides an electrochemical reaction tank for circulating water treatment. The cathode plate, composite membrane electrode plate, and anode plate are connected to the top edge of the reaction tank via a support plate, located inside a limiting groove. Compared to the traditional method of tightening and loosening bolts individually, this structure makes electrode removal and placement much more convenient and faster, allowing operators to easily perform maintenance and cleaning, thus improving work efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: An electrochemical reaction tank for circulating water treatment mainly includes a reaction tank body, a limiting plate, a cathode plate, a composite membrane electrode plate, an anode plate, a support plate, a connecting assembly, a sealing cover, an inlet pipe, and an outlet pipe. The reaction tank body is internally configured as a cavity structure. The limiting plate is installed on the inner wall of the reaction tank body, and a limiting groove is formed between adjacent limiting plates. The cathode plate, composite membrane electrode plate, and anode plate are alternately installed at equal intervals in the limiting groove. The composite membrane electrode plate separates the cathode plate and the anode plate. The support plate is installed at the top of the cathode plate, composite membrane electrode plate, and anode plate. The cathode plate, composite membrane electrode plate, and anode plate overlap the top edge of the reaction tank body through the support plate for easy handling and placement. The connecting assembly of the limiting plate, cathode plate, and composite membrane electrode plate is installed on the support plate. The sealing cover is installed at the top of the reaction tank body, and a locking buckle is provided on the sealing cover and the reaction tank body. The inlet pipe is installed at the bottom of the reaction tank body, and the outlet pipe is installed on the side wall of the reaction tank body. The inlet pipe and the outlet pipe are connected to the interior of the reaction tank body.

[0006] The connecting assembly includes a connecting plate, a Y-shaped connecting plate, a connecting post, and a handle. The connecting plate and the Y-shaped connecting plate are mounted on the support plate, the connecting post is mounted between the connecting plate and the Y-shaped connecting plate, and the handle is mounted on the top of the Y-shaped connecting plate.

[0007] The latch includes a snap-fit ​​component and a sealing ring. The snap-fit ​​component is installed on the sealing cover and the reaction tank body, and the sealing ring is installed on the top of the reaction tank body. The sealing cover is sealed to the top of the reaction tank body through the snap-fit ​​component and the sealing ring.

[0008] The width of the limiting groove is adapted to the thickness of the cathode plate, composite film electrode plate, and anode plate.

[0009] The cathode plate and anode plate are coated with a nano-coating to improve electrochemical catalytic efficiency. The coating material is platinum or titanium-based oxide.

[0010] The beneficial effects of this utility model are:

[0011] The cathode plate, composite membrane plate, and anode plate are connected to the top edge of the reaction tank via a support plate and are located inside the limiting groove. Compared with the traditional method of tightening and loosening bolts one by one, this structure makes it more convenient and faster to remove and place the electrode plates. Operators can easily perform maintenance and cleaning, improving work efficiency. The water inlet pipe is installed at the bottom of the reaction tank, and the water outlet pipe is installed on the side wall of the reaction tank. After the water enters from the bottom, it can flow more evenly through each electrode plate in the reaction tank, making the electrochemical oxidation / reduction reaction more complete and improving the treatment effect of the circulating water treatment system on different water qualities. The sealing cover ensures the sealing of the inside of the reaction tank and reduces the fluctuation of reaction efficiency caused by environmental factors. Attached Figure Description

[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0020] This utility model discloses an electrochemical reaction tank for circulating water treatment. The electrochemical reaction tank mainly includes a reaction tank body 1, a limiting plate 2, a cathode plate 3, a composite membrane electrode plate 4, an anode plate 5, a support plate 6, a connecting assembly 7, a sealing cover 8, an inlet pipe 9, and an outlet pipe 10. The reaction tank body 1 has an internal cavity structure. The limiting plates 2 are installed on the inner wall of the reaction tank body 1, and adjacent limiting plates 2 form limiting grooves 21. The cathode plate 3, the composite membrane electrode plate 4, and the anode plate 5 are alternately installed at equal intervals within the limiting grooves 21. The composite membrane electrode plate 4 holds the cathode plate 3... The anode plate 5 is separated, and the support plate 6 is installed on the top of the cathode plate 3, the composite membrane electrode plate 4, and the anode plate 5. The cathode plate 3, the composite membrane electrode plate 4, and the anode plate 5 are connected to the top edge of the reaction tank 1 through the support plate 6 for easy handling and placement. The connecting assembly 7 of the limiting plate 2, the cathode plate 3, and the composite membrane electrode plate 4 is installed on the support plate 6. The sealing cover 8 is installed on the top of the reaction tank 1. The sealing cover 8 and the reaction tank 1 are provided with a locking buckle 11. The water inlet pipe 9 is installed at the bottom of the reaction tank 1, and the water outlet pipe 10 is installed on the side wall of the reaction tank 1. The water inlet pipe 9 and the water outlet pipe 10 are connected to the inside of the reaction tank 1.

[0021] like Figure 4 As shown, the connecting assembly 7 includes a connecting plate 71, a Y-shaped connecting plate 72, a connecting post 73, and a handle 74. The connecting plate 71 and the Y-shaped connecting plate 72 are mounted on the support plate 6, the connecting post 73 is mounted between the connecting plate 71 and the Y-shaped connecting plate 72, and the handle 74 is mounted on the top of the Y-shaped connecting plate 72. The connecting assembly 7 cooperates with the limiting groove 21 to realize the quick assembly and disassembly of the cathode plate 3, the composite film electrode plate 4, and the anode plate 5, thereby reducing maintenance costs.

[0022] like Figure 5 As shown, the latch 11 includes a snap-fit ​​component 111 and a sealing ring. The snap-fit ​​component 111 is installed on the sealing cover 8 and the reaction tank 1, and the sealing ring is installed on the top of the reaction tank 1. The sealing cover 8 is sealed to the top of the reaction tank 1 through the snap-fit ​​component 111 and the sealing ring. The sealing cover 8 is tightly connected to the top of the reaction tank 1 through the snap-fit ​​component 111, and the sealing ring ensures the reliability of the seal, prevents liquid leakage in the reaction tank, maintains the stability of the internal reaction environment, and avoids external substances from entering the reaction system and interfering with the reaction.

[0023] like Figure 7As shown, the width of the limiting groove 21 is adapted to the thickness of the cathode plate 3, the composite film electrode plate 4, and the anode plate 5; the cathode plate 3, the composite film electrode plate 4, and the anode plate 5 can be easily installed alternately at equal intervals in the limiting groove 21.

[0024] The cathode plate 3 and anode plate 5 are coated with a nano-coating to improve electrochemical catalytic efficiency. The coating material is platinum or titanium-based oxide, which helps to improve reaction efficiency and stability.

[0025] Work process:

[0026] The circulating water to be treated is injected into the cavity through the inlet pipe 9 located at the bottom of the reaction tank 1. The water flows from bottom to top, ensuring uniform distribution within the cavity of the reaction tank 1. The sealing cover 8 is tightly fastened to the reaction tank 1 by the locking buckle 11. The snap-fit ​​element 111 in the locking buckle 11 cooperates with the sealing ring to form a reliable sealing structure, preventing liquid leakage. The water flows sequentially through the gaps between the alternately arranged anode plates 5, composite membrane plates 4, and cathode plates 3. The cathode plate 3 undergoes a reduction reaction under energized conditions, promoting the reduction of heavy metal ions (such as Cu²⁺, Cr) in the water. 6 The reduction and precipitation of ⁺) occurs, and the anode plate undergoes an oxidation reaction, decomposing organic pollutants and generating active oxygen substances (such as ·OH) with bactericidal effects. The composite membrane plate 4 acts as an ion exchange membrane or proton exchange membrane, separating the cathode area and the anode area, preventing direct mixing of the solutions in the two areas, while allowing specific ions to pass through to maintain current conduction, which helps to improve reaction efficiency and stability. Under the action of the electric field, ions in the circulating water will migrate and react, thereby achieving functions such as sterilization, algae removal, and heavy metal removal. The treated water gradually rises in the reaction tank 1 and is finally discharged from the outlet pipe 10 on the upper side wall, ensuring smooth water flow.

[0027] When cleaning or replacing the electrode plates is required, open the snap-fit ​​connector 111 and remove the sealing cover 8. Operate through the connecting component 7, hold the anti-slip handle 74 at the top of the Y-shaped connecting plate 72, and pull the handle 74 upward to remove the cathode plate 3, composite film electrode plate 4, and anode plate 5 that need to be cleaned or replaced from the limiting groove 21. After maintenance, re-insert the cathode plate 3, composite film electrode plate 4, and anode plate 5 into the limiting groove 21, overlap them through the support plate 6, and lock the latch 11 and sealing cover 8 to resume operation. The connecting component 7 cooperates with the limiting groove 21 to achieve quick disassembly and assembly of the cathode plate 3, composite film electrode plate 4, and anode plate 5, reducing maintenance costs.
