[0002] Sodium hypochlorite, as a highly efficient and economical disinfectant, rapidly kills bacteria and viruses due to its strong oxidizing properties, and is low in cost and leaves easily degradable residues. In municipal applications, it is used for disinfection in water treatment plants to ensure drinking water safety; in wastewater treatment, it degrades organic pollutants and kills bacteria. In the food processing industry, it is used for disinfection of workshops and equipment; in aquaculture, it improves water quality and inhibits diseases. It is also suitable for disinfection in public places such as hospitals and schools, as well as for preserving fruits and vegetables in agriculture, becoming a core agent for hygiene protection in multiple fields.

[0003] Existing continuous sodium hypochlorite electrolyzers suffer from cumbersome electrode installation and disassembly, making subsequent maintenance and replacement inconvenient; uneven distribution of raw material solution leads to incomplete local reactions at the electrodes, affecting the sodium hypochlorite generation efficiency; impurities are easily mixed into the solution as it flows through each chamber, making it difficult to guarantee purity; the lack of effective liquid level monitoring and control makes it easy for liquid level fluctuations to affect the stability of continuous production; insufficient sealing performance allows external contamination to easily penetrate, and the concentration of the finished product cannot be monitored in real time. Utility Model Content

[0004] The purpose of this invention is to solve the problems of inconvenient electrode maintenance, uneven raw material distribution, low solution purity, and poor production stability in existing devices, and to propose a continuous sodium hypochlorite electrolytic cell.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a continuous sodium hypochlorite electrolytic cell, comprising a cell body, partitions, an electrolysis chamber, a buffer chamber, a precipitation chamber, and an electrode assembly. Two partitions are fixedly connected to the inner wall of the cell body, dividing the internal space of the cell body into three chambers: the electrolysis chamber, the buffer chamber, and the precipitation chamber. An electrode assembly is disposed on the inner wall of the electrolysis chamber. The electrode assembly includes an installation groove formed on the inner wall of the electrolysis chamber, and a magnetic suction plate is fixedly connected to the inner wall of the installation groove. An electrode frame is fitted onto the inner wall of the mounting slot. A magnetic groove is formed on the back side of the electrode frame. A slot is formed on the inner wall of the electrode frame. A locking block is fitted onto the inner wall of two slots. An electrode block is fitted onto the inner wall of the electrode frame. The two locking blocks are fixedly connected to the back side of the electrode block. Two sealing waterproof strips are fixedly connected to the surface of the electrode frame. One sealing waterproof strip is fixed at the contact gap between the electrode frame and the mounting slot, and the other sealing waterproof strip is fixed at the contact gap between the electrode block and the electrode frame.

[0006] Furthermore, an inlet pipe is fixedly connected to the top of one side of the tank, and a flow regulating valve is fixedly connected to the middle end of the inlet pipe.

[0007] Furthermore, a diverter pipe is fixedly connected to the outlet end of the inlet pipe, and the two outlets of the diverter pipe are located at the top of the electrode block surface.

[0008] Furthermore, the surface of the partition is provided with filter holes, and a top plate is fixedly connected to the top of the buffer cavity.

[0009] Furthermore, a liquid level sensor is fixedly connected to the bottom of the top plate, and a sealing top cover is rotatably connected to the top of the tank.

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

[0013] In this invention, by setting up an electrode assembly, the mounting groove provides a positioning and installation base for the electrode frame. The magnetic plate and magnetic groove work together to achieve quick assembly and disassembly of the electrode frame, solving the problem of inconvenient maintenance of traditional electrodes. The slot and locking block securely hold the electrode block, preventing displacement during electrolysis and ensuring stable contact between the electrode and the electrolyte. Two sealing waterproof strips respectively seal the gaps between the electrode frame and the mounting groove, and between the electrode block and the electrode frame, preventing electrolyte leakage and maintaining a stable reaction environment within the electrolysis chamber. This ensures the electrode block participates efficiently in the electrolysis reaction. The inlet pipe continuously supplies the raw material liquid for electrolysis, and the flow regulating valve flexibly controls the inlet rate to adapt to different production loads. The flow tube evenly distributes the raw material solution to the top of the electrode block, ensuring sufficient reaction on the electrode surface and improving the sodium hypochlorite generation efficiency. The filter holes of the baffle filter impurities in the solution, allowing the electrolyzed solution to flow into the precipitation chamber after being stabilized in the buffer chamber, further improving purity. The liquid level sensor monitors the liquid level in the buffer chamber in real time, facilitating timely adjustment of the liquid inlet and ensuring stable continuous production. The sealed top cover, combined with the air cushion sealing strip, enhances the tank's sealing performance and prevents external contamination. The outlet pipe leads the finished solution to the collection tank, and the concentration sensor detects the concentration in real time to ensure product quality. Overall, this improves electrolysis efficiency, solution purity, and production stability, meeting the continuous preparation needs of sodium hypochlorite in multiple fields.

Two partitions 2 are fixedly connected to the inner wall of the tank body 1, and the two partitions 2 divide the space inside the tank body 1 into three chambers, namely the electrolysis chamber 3, the buffer chamber 4, and the precipitation chamber 5. The electrode assembly 6 is provided on the inner side wall of the electrolysis chamber 3.

[0023] The specific setup and function of electrode assembly 6 will be discussed below.

[0024] In this embodiment: the electrode assembly 6 includes an installation groove 61 formed in the inner wall of the electrolysis chamber 3. A magnetic suction plate 62 is fixedly connected to the inner wall of the installation groove 61. An electrode frame 63 is snapped onto the inner wall of the installation groove 61. A magnetic groove 64 is formed on the back side of the electrode frame 63. A slot 65 is formed on the inner wall of the electrode frame 63. A locking block 66 is snapped onto the inner wall of the two slots 65. An electrode block 67 is snapped onto the inner wall of the electrode frame 63.

One sealing waterproof strip 68 is fixed at the contact gap between the electrode frame 63 and the installation groove 61, and the other sealing waterproof strip 68 is fixed at the contact gap between the electrode block 67 and the electrode frame 63.

[0025] The aforementioned components achieve the following effects: the mounting groove 61 provides precise installation positioning for the electrode frame 63; the magnetic suction plate 62 and the magnetic groove 64 engage to achieve quick assembly and disassembly of the electrode frame 63, facilitating subsequent maintenance and replacement of the electrode assembly 6; the slot 65 and the locking block 66 securely hold the electrode block 67, preventing displacement of the electrode block 67 during electrolysis and ensuring stable contact between the electrode and the electrolyte; two sealing waterproof strips 68 respectively seal different connection gaps to prevent electrolyte leakage, maintain a stable reaction environment within the electrolysis chamber 3, and ensure that the electrode block 67 efficiently participates in the electrolysis reaction to generate sodium hypochlorite.

[0026] Please see Figure 5 Specifically, an inlet pipe 7 is fixedly connected to the top of one side of the tank 1, and a flow regulating valve 8 is fixedly connected to the middle of the inlet pipe 7.

[0027] The effects achieved by the above components are as follows: by setting up the liquid inlet pipe 7, the raw material liquid is continuously supplied to the electrolytic reaction to meet the needs of continuous production; the flow regulating valve 8 flexibly controls the input speed of the raw material liquid, adapts to different electrolytic loads, avoids excessive raw material liquid leading to insufficient or insufficient reaction affecting production capacity, and ensures the stability of the electrolysis process.

[0028] Please see Figure 5 Specifically, the outlet end of the inlet pipe 7 is fixedly connected to the diverter pipe 9, and the two outlets of the diverter pipe 9 are located at the top of the surface of the electrode block 67.

[0029] The effect achieved by the above components is as follows: by setting the diversion pipe 9, the raw material liquid is evenly distributed to the top of the electrode block 67, ensuring that the surface of the electrode block 67 is fully covered by the raw material liquid, avoiding the dead zone caused by the lack of local raw material liquid, and improving the sodium hypochlorite generation efficiency and solution uniformity.

[0030] Please see Figure 4 Specifically, the surface of the partition 2 is provided with filter holes 10, and the top of the buffer cavity 4 is fixedly connected with a top plate 11.

[0031] The effects achieved by the above components are as follows: by setting the filter holes 10, the solution generated in the electrolysis chamber 3 flows smoothly into the buffer chamber 4, while filtering out unreacted solid impurities and improving the purity of the solution; the top plate 11 seals the top of the buffer chamber 4 to prevent the solution from evaporating or being contaminated by the outside world, providing a stable buffer space for the solution and avoiding the impact of subsequent sedimentation chamber 5 level fluctuations on the sedimentation effect.

[0032] Please see Figure 3-5 Specifically, a liquid level sensor 12 is fixedly connected to the bottom of the top plate 11, and a sealing top cover 13 is rotatably connected to the top of the tank body 1.

[0033] The effects achieved by the above components are as follows: by setting up a liquid level sensor 12 to monitor the liquid level in the buffer chamber 4 in real time, timely feedback of abnormal liquid level is provided, which facilitates the control of the liquid inlet rate and ensures the balance of solution flow in each chamber; the sealed top cover 13 can be opened and closed flexibly, isolating external pollution when closed, and facilitating the inspection and maintenance of internal components of the tank 1 when open.

[0034] Please see Figure 3 Specifically, an air cushion sealing strip 14 is fixedly connected to the top of the tank 1, and the surface of the air cushion sealing strip 14 abuts against the inner wall of the sealing top cover 13.

[0035] The effect achieved by the above components is as follows: by setting the air cushion sealing strip 14 to fill the gap between the sealing top cover 13 and the tank body 1, the overall sealing of the tank body 1 is enhanced, further preventing external impurities from entering and the solution from evaporating, and ensuring that the sodium hypochlorite solution is treated in a clean and stable environment.

[0037] The effects achieved by the above components are as follows: the finished product solution after precipitation and purification is exported by setting the liquid outlet pipe 15, and the finished product is centrally stored in the collection tank 17 to meet the collection needs of continuous production; the concentration sensor 16 detects the solution concentration in real time to ensure that the output solution meets the quality standards, which facilitates timely adjustment of electrolysis parameters and improves the product qualification rate.

[0038] Working principle: By setting up electrode assembly 6, mounting groove 61 provides a positioning and installation base for electrode frame 63. Magnetic suction plate 62 and magnetic groove 64 are attracted and cooperate to achieve quick assembly and disassembly of electrode frame 63, solving the problem of inconvenient maintenance of traditional electrodes. Slot 65 and locking block 66 fix electrode block 67 to prevent displacement during electrolysis, ensuring stable contact between the electrode and electrolyte. Two sealing waterproof strips 68 respectively seal the gaps between electrode frame 63 and mounting groove 61, and between electrode block 67 and electrode frame 63, preventing electrolyte leakage and maintaining a stable reaction environment within electrolysis chamber 3, ensuring efficient participation of electrode block 67 in the electrolysis reaction. Inlet pipe 7 continuously supplies raw material liquid for electrolysis, and flow regulating valve 8 flexibly controls the inlet rate to adapt to different production processes. The production load is controlled by the diversion pipe 9, which evenly distributes the raw material liquid to the top of the electrode block 67 to ensure sufficient reaction on the electrode surface and improve the sodium hypochlorite production efficiency. The filter holes 10 of the baffle 2 filter impurities in the solution, so that the electrolyzed solution flows into the precipitation chamber 5 after being stabilized and buffered by the buffer chamber 4, further improving the purity. The liquid level sensor 12 monitors the liquid level in the buffer chamber 4 in real time, which facilitates timely adjustment of the liquid inlet and ensures stable continuous production. The sealed top cover 13, together with the air cushion sealing strip 14, enhances the sealing of the tank and prevents external contamination. The liquid outlet pipe 15 leads the finished solution to the collection tank 17. The concentration sensor 16 detects the concentration in real time to ensure product quality. Overall, the electrolysis efficiency, solution purity and production stability are improved, meeting the continuous preparation needs of sodium hypochlorite in multiple fields.
