Description

Technical Field

[0001] This utility model belongs to the field of electrolytic cell technology, and specifically relates to an easy-to-maintain electrolytic cell structure. Background Technology

[0002] Electrolytic cells, also known as "electrolytic oxidation-reduction reactors," are widely used in wastewater treatment. Their core principle is to utilize an external electric field to drive an oxidation-reduction reaction on the electrode surface. Through processes such as "direct electrode reaction," "indirect active substance action," and "physical auxiliary effects" (flocculation, flotation), pollutants such as organic matter, heavy metal ions, and suspended particles in wastewater are decomposed, transformed, or separated, thereby achieving water purification. Their basic principle can be broken down into three parts: "core electrochemical reaction," "removal mechanisms of the three major pollutants," and "key influencing factors."

[0003] The core structure of a wastewater treatment electrolytic cell is a closed system consisting of electrodes, electrolyte, and external circuitry. The wastewater itself serves as the electrolyte (containing electrolyte ions such as chloride, sulfate, and sodium ions). Under the influence of an applied DC electric field, directional oxidation and reduction reactions occur at the anode and cathode, respectively, providing the basis for electron transfer and the generation of active substances for pollutant removal. This type of electrolytic cell has significant advantages: the electron transfer process occurs only between the electrodes and the wastewater components, eliminating the need for additional oxidizing or reducing agents and avoiding secondary pollution caused by chemical reagents; the reaction rate and conditions can be flexibly controlled by adjusting the applied current; the free radicals generated during the reaction can non-selectively degrade organic pollutants in the wastewater, converting them into carbon dioxide, water, or simple organic matter, with virtually no secondary pollution; and the electrochemical processes are mostly carried out at ambient temperature and pressure, ensuring safe and mild operation.

[0004] However, despite the high efficiency and environmental friendliness of wastewater treatment electrolyzers during operation, they still face problems such as frequent maintenance and difficult cleaning in long-term use. Electrodes are the core functional components of the electrolyzer; their materials are prone to "oxidative corrosion" or "dissolution and consumption" during repeated oxidation-reduction reactions, leading to a shortened service life. Simultaneously, when wastewater contains high-hardness ions (such as calcium and magnesium ions), calcium carbonate and magnesium hydroxide scale easily form on the cathode surface, hindering electron transfer; the anode surface may adsorb organic residues or metal oxides, causing "passivation." To maintain electrolysis efficiency, regular acid washing (such as dilute hydrochloric acid cleaning) or mechanical cleaning is usually required, generally at least once a week, making the structural disassembly and reassembly a key influencing factor.

[0005] Currently, electrolytic cells used in wastewater treatment generally employ a bolt-through fixing structure, where the electrolysis frame is securely connected to the cell body using multiple sets of bolts. While this connection method ensures the stability of the electrolysis unit, cleaning and maintenance require disassembling each bolt individually, which is cumbersome, time-consuming, and significantly reduces maintenance efficiency. Furthermore, to enhance the stability of the electrode plate assembly, existing structures often use long bolts penetrating the anode and cathode plates for reinforcement, further increasing the disassembly and assembly steps and making it difficult to quickly remove the electrode plates for cleaning or replacement. Since threaded connections are prone to rusting, stripping, or jamming in high-humidity and corrosive environments, maintenance is not only time-consuming and labor-intensive but also prone to damaging structural components, affecting subsequent assembly accuracy.

[0006] In summary, existing electrolytic cells still have significant shortcomings in terms of low disassembly and assembly efficiency, cumbersome maintenance operations, and structural fixing methods that are not conducive to rapid cleaning. In particular, the need for frequent cleaning and maintenance in the wastewater treatment process highlights the importance of structural improvement. Utility Model Content

[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide an easy-to-maintain electrolytic cell structure that can effectively shorten maintenance time and improve cleaning efficiency, so as to solve the above-mentioned problems existing in the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An easy-to-maintain electrolytic cell structure includes a cell body, an electrolytic frame, and quick-release buckles. L-shaped hooks are uniformly welded to both sides of the upper surface of the cell body, and an electrolytic chamber is provided inside the cell body. The electrolytic frame is inserted and installed inside the electrolytic chamber. The quick-release buckles and L-shaped hooks are correspondingly arranged, and T-shaped hook heads are movably installed at both ends of the quick-release buckles via rotating shafts. Threaded holes are provided at both ends of the quick-release buckles, and the quick-release buckles are hooked to the L-shaped hooks via the T-shaped hook heads. A compression screw is installed inside the threaded hole via threaded engagement. The bottom end of the compression screw is tightly pressed against the upper surface of the electrolytic frame. The electrolytic frame and the cell body are pressed and fixed by the compression screw.

[0010] Furthermore, the electrolytic frame includes a cover plate and an electrode plate assembly, wherein the electrode plate assembly includes an anode plate, a cathode plate, and an electrode plate clamp.

[0011] Furthermore, multiple anode plates and cathode plates are provided, and the multiple anode plates and cathode plates are arranged alternately and crosswise. An anode parallel plate is provided at the top of the anode plate, and a cathode parallel plate is provided at the top of the cathode plate.

[0012] Furthermore, bolts pass through the anode plate, the anode parallel plate, and the cover plate, and the anode plate, the anode parallel plate, and the cover plate are fixed together by bolts. Similarly, bolts pass through the cathode plate, the cathode parallel plate, and the cover plate, and the cathode plate, the cathode parallel plate, and the cover plate are fixed together by bolts.

[0013] Furthermore, the electrode plate bracket includes a bracket horizontal plate and a bracket long bolt. A foamed support block is bonded and fixed to one side of the bracket horizontal plate. Electrode plate limiting grooves are evenly opened inside the foamed support block. The electrode plate limiting grooves are correspondingly arranged with the anode plate or cathode plate.

[0014] Furthermore, the hoop cross plate is inserted into the edge of the anode plate or cathode plate through the electrode plate limiting groove, and the hoop long bolt is installed through the ends of the two hoop cross plates, and the two hoop cross plates are connected and fixed together by the hoop long bolt.

[0015] Furthermore, a connecting rod is provided on the upper surface of one end of both the electrode plate clamp and the anode parallel plate, and the connecting rod extends through and protrudes from the upper surface of the cover plate.

[0016] Furthermore, a sealing gasket is laid between the cover plate and the groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention replaces the traditional through-bolt fixing method with an assembly structure combining quick-release plates and compression screws, solving the problem of existing electrolytic cells requiring the removal of bolts one by one during cleaning and maintenance, which is cumbersome and time-consuming. By setting L-shaped hook claws on the tank body and installing T-shaped hook heads at both ends of the quick-release plates, the quick-release plates can be quickly engaged with the L-shaped hook claws. Combined with the compression screws, the upper surface of the electrolytic frame is pressed and fixed, forming a stable connection between the electrolytic frame and the tank body. During maintenance, simply loosening the compression screws allows the quick-release plates to be removed, enabling direct disassembly of the entire electrolytic frame. This achieves rapid assembly and disassembly without removing the through bolts, significantly shortening maintenance time and improving cleaning and repair efficiency. It is particularly suitable for applications requiring high-frequency maintenance in wastewater electrolysis treatment systems.

[0019] This invention solves the problems of difficult electrode replacement and complex disassembly / reassembly procedures in existing electrolytic cells by incorporating a detachable electrode assembly structure inside the electrolysis frame. The electrode assembly consists of multiple sets of anode plates, cathode plates, and electrode clamps. The clamps are secured by horizontal plates and long bolts, ensuring stable spacing and uniform electric field between the plates during operation. When replacing or cleaning the anode or cathode plates, simply loosening the clamp bolts allows for easy separation of the clamps and quick removal of the plates. Compared to traditional through-bolt fixing, this structure significantly reduces the number of threaded operations during maintenance, avoids jamming due to thread corrosion or stripping, improves the reliability and service life of repeated disassembly and reassembly, and ensures the long-term stability of the wastewater treatment electrolysis process.

[0031] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0032] like Figures 1-4 As shown, an easy-to-maintain electrolytic cell structure includes a cell body 101, an electrolytic frame 102, and a quick-release buckle plate 103. The cell body 101 is generally a rectangular box structure, welded from anti-corrosion alloy sheet. L-shaped hook claws 111 are uniformly welded to both sides of the upper surface of the cell body 101. The L-shaped hook claws 111 are made of stainless steel, possessing good mechanical strength and corrosion resistance, and are used to form stable hook supports when the quick-release buckle plate 103 is installed. An electrolytic chamber 112 is provided inside the cell body 101, which is used to contain the electrolyte and the electrolytic frame 102. The internal space dimensions match the shape of the electrolytic frame 102 to ensure a uniform electric field distribution when energized. The electrolytic frame 102 is plugged into the electrolytic chamber 112, and the plug-in connection ensures a smooth and reliable installation and removal process. The quick-release buckle plate 103 and the L-shaped hook claws 111 are connected to the electrolytic frame 102. Hook claws 111 are correspondingly provided, and T-shaped hook heads 131 are movably installed at both ends of the quick-release buckle plate 103 via rotating shafts. During installation, the T-shaped hook heads 131 can be rotated and inserted under the L-shaped hook claws 111 to form a mechanical lock. Both ends of the quick-release buckle plate 103 are provided with threaded holes 132. A compression screw 107 is installed inside the threaded hole 132 by threaded engagement. The bottom end of the compression screw 107 is close to the upper surface of the compression electrolysis frame 102. By tightening the compression screw 107, the electrolysis frame 102 can be limited and pressed and fixed. The electrolysis frame 102 and the tank 101 are reliably connected by the axial force of the compression screw 107, so that the entire electrolysis device remains stable during operation and prevents positional displacement caused by electrolyte agitation or bubble impact, thereby ensuring the uniformity of the electric field and reaction efficiency of the wastewater in the electrochemical reaction process.

[0033] like Figure 1 , Figure 2 , Figures 5-7As shown, the electrolysis frame 102 includes a cover plate 121 and an electrode assembly 105. The cover plate 121 is made of acid and alkali resistant resin composite material and is used to seal the upper end of the electrolysis chamber 112 and provide electrical connection support. The electrode assembly 105 consists of multiple sets of anode plates 151, cathode plates 152 and electrode clamps 153. The electrode assembly 105 forms a closed system of "electrode-electrolyte-external circuit" in the electrolysis cell 101. The electrolyte is wastewater containing chloride ions, sulfate ions, sodium ions, etc. A potential difference is generated between the anode plate 151 and the cathode plate 152 to realize the oxidation-reduction reaction, thereby decomposing or transforming organic matter, heavy metals and suspended particles in the wastewater.

[0034] like Figures 5-7 As shown, multiple anode plates 151 and cathode plates 152 are provided, and the multiple anode plates 151 and cathode plates 152 are arranged alternately and crosswise. The anode plates 151 are made of titanium-based platinum-plated material, which has excellent conductivity and corrosion resistance. The cathode plates 152 are made of stainless steel or graphite material, which can effectively promote the reduction reaction. An anode parallel plate 154 is provided at the top of the anode plates 151 to electrically connect the multiple anode plates 151, so that the potential among the anode plates 151 is balanced and the current is evenly distributed. A cathode parallel plate 155 is provided at the top of the cathode plates 152, which is used to centrally conduct the cathode current and ensure the stability of the electrolysis reaction. This alternating and cross-arranged electrode structure forms a multi-channel electric field region, which enhances the efficiency of pollutant oxidation and decomposition.

[0035] like Figure 1 , Figure 2 , Figures 5-7 As shown, bolts pass through the anode plate 151, the anode parallel plate 154, and the cover plate 121, and the anode plate 151, the anode parallel plate 154, and the cover plate 121 are fixed together by bolts; bolts also pass through the cathode plate 152, the cathode parallel plate 155, and the cover plate 121, and the cathode plate 152, the cathode parallel plate 155, and the cover plate 121 are fixed together by bolts; all bolts are made of corrosion-resistant alloy material, and anti-oxidation grease is applied to the threads to prevent rust in the sewage environment; this through-bolt fastening method ensures the conductivity stability of the anode plate 151 and the cathode plate 152, and at the same time facilitates quick disassembly for replacement of the plates during maintenance.

[0036] like Figures 5-9As shown, the electrode clamp 153 includes a clamp cross plate 156 and clamp long bolts 157; the clamp cross plate 156 is made of high-strength insulating composite board and is used to support the electrode group and maintain its parallel spacing; a foamed support block 158 is bonded and fixed to one side of the clamp cross plate 156. The foamed support block 158 has excellent elasticity and buffering performance, which can prevent the electrode from shaking due to current impact or bubble disturbance during electrolysis; the interior of the foamed support block 158 is uniformly provided with electrode limiting grooves 159, which are correspondingly set with the edge of the anode plate 151 or cathode plate 152 to ensure the accurate position of the electrode and avoid displacement, further ensuring the symmetry of the electric field distribution and the uniformity of the reaction.

[0037] like Figures 5-9 As shown, the clamping cross plate 156 is inserted into the edge of the anode plate 151 or cathode plate 152 via the electrode plate limiting groove 159; the clamping long bolt 157 is installed through the ends of the two clamping cross plates 156, and the two clamping cross plates 156 are connected and fixed together by the clamping long bolt 157; after being locked, the clamping long bolt 157 forms a clamping and pressing effect on the electrode plate assembly 105 to prevent the electrode plates from loosening; this structure allows the electrode plate clamping 153 to be disassembled and installed independently. When cleaning or replacing the anode plate 151 and cathode plate 152, maintenance personnel only need to loosen the clamping long bolt 157 to separate the electrode plate clamping 153, achieving quick maintenance and avoiding the cumbersome disassembly problem caused by the traditional through bolt fixing structure.

[0038] like Figure 1 , Figure 2 , Figure 5 As shown, a connecting rod 106 is provided on the upper surface of one end of the electrode clamp 153 and the anode parallel plate 154. The connecting rod 106 is made of copper-plated nickel material, which has high conductivity and good oxidation resistance. The connecting rod 106 penetrates through and protrudes from the upper surface of the cover plate 121 for connection with external power supply wires to realize current input and output. The weld between the connecting rod 106 and the parallel plate is treated with anti-corrosion sealing to ensure long-term stable operation in the high humidity wastewater electrolysis environment.

[0039] like Figure 1 and Figure 2 As shown, a sealing gasket 104 is laid between the cover plate 121 and the tank body 101. The sealing gasket 104 is made of acid and alkali resistant rubber material and is used to prevent electrolyte leakage and ensure the sealing of the electrolysis reaction chamber. The sealing gasket 104 is laid continuously along the edge of the cover plate 121 and forms a closed sealing structure after the cover plate 121 and the tank body 101 are pressed together, which effectively prevents electrolyte evaporation and leakage, and ensures the safety and environmental cleanliness of the electrolysis reaction process.

[0040] The working principle of this utility model is as follows:

[0041] This solution eliminates the bolt-through fixing method and adopts a quick-release buckle plate 103, combined with L-shaped hook claws 111 on both sides of the tank body 101 and a compression screw 107 to achieve a compression fixing method. The electrolysis frame 102 is fixed to the tank body 101 by compression. When disassembling, it is not necessary to completely remove the compression screw 107. Just screw the compression screw 107 until the quick-release buckle plate 103 can be removed. Then remove the quick-release buckle plate 103 to release the electrolysis frame 102 from the fixation. Then the electrolysis frame 102 can be removed for cleaning and maintenance. This shortens the disassembly time and improves the efficiency of cleaning and maintenance.

[0042] When fine cleaning is required, or when replacing the corresponding anode plate 151 or cathode plate 152, first remove the bolts that fix the anode plate 151, cathode plate 152, anode parallel plate 154, cathode parallel plate 155 and cover plate 121, and then remove the long bolts 157 of the clamp. At this time, the anode plate 151 and cathode plate 152 can be detached from the clamp 153, and the corresponding plates can be removed for cleaning or replacement. Compared with the fixing method that passes through the anode plate 151 and cathode plate 152, the clamp 153 limiting fixing method is easier to disassemble and maintain, reduces the disassembly and maintenance time, and facilitates inspection and maintenance.

[0043] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
