Description

Technical Field

[0001] This utility model relates to the field of electrolysis technology, specifically to an insulating mesh for an electrolytic cell and an electrolytic cell. Background Technology

[0002] In the electrolysis industry, the electrolytic cell is the core equipment. The material transformation is achieved through the redox reaction between the electrodes. In order to improve electrolysis efficiency, ensure reaction purity, and avoid short circuits or side reaction interference between electrodes, it is usually necessary to set up an isolation structure in the electrolytic cell. Among them, the insulating mesh is one of the key components.

[0003] Traditional electrolytic cells have isolation structures where some of the meshes are made of metal or conductive materials, which can easily cause leakage between electrodes, increase energy consumption, and even lead to safety hazards. At the same time, traditional meshes have low filtration accuracy and cannot effectively intercept solid particles generated in the reaction. If these particles adhere to the electrode surface, they will reduce electrolysis efficiency.

[0004] The target products generated during electrolysis need to be collected in a targeted manner to improve the recovery rate. However, traditional mesh only serves as an isolation device and lacks active flow guidance and aggregation structure, resulting in the products being dispersed in the electrolyte and increasing the cost of subsequent separation.

If these particles adhere to the electrode surface, they will reduce the electrolysis efficiency.

[0025] refer to Figure 1 and Figure 4 In some embodiments, the insulating collection assembly 3 further includes a linkage shaft 3-8; The connecting shaft 3-8 is fixedly connected to the drive shaft 3-5. The upper end face of the connecting shaft 3-8 is provided with a toggle piece, which is fixedly fitted to the connecting shaft 3-8.

[0026] In some examples, the insulating collection assembly 3 also includes a connecting shaft 3-8, which is fixedly connected to the drive shaft 3-5, for example, by a coupling. An actuating plate is provided on the upper end face of the connecting shaft 3-8, and the actuating plate is fixedly fitted to the connecting shaft 3-8. When the connecting shaft 3-8 rotates with the drive shaft 3-5, the actuating plate will also rotate, further assisting the flow and processing of the liquid.

[0027] like Figures 1-4 As shown, on the other hand, this utility model also provides a drive sealing component 4, including a mounting frame 4-1; The mounting frame 4-1 is set on the lower end face of the collecting cone cover 3-3. The bottom of the mounting frame 4-1 is provided with a fixing frame 4-2. The inner side wall of the fixing frame 4-2 is provided with a clearance groove 4-3. The interior of the clearance groove 4-3 is provided with a sealing ball 4-4. The sealing ball 4-4 is sealed and fitted with the collecting cone cover 3-3.

[0028] In some examples, the drive sealing assembly 4 is located at the bottom of the tank 1. It includes a mounting frame 4-1, which is installed on the lower end face of the collecting cone hood 3-3 and can be fixed by bolts or the like. A fixing frame 4-2 is provided at the bottom of the mounting frame 4-1. A clearance groove 4-3 is opened on the inner side wall of the fixing frame 4-2. A sealing ball 4-4 is placed inside the clearance groove 4-3. The sealing ball 4-4 is made of a material with a certain elasticity and sealing properties, such as rubber. It is sealed and fitted with the collecting cone hood 3-3 to control the opening and closing of the lower end of the collecting cone hood 3-3.

[0029] refer to Figure 1 and Figure 4 In some embodiments, the drive sealing assembly 4 further includes a lifting shaft 4-5; The lifting shaft 4-5 is located on the lower end face of the sealing ball 4-4. A return spring 4-6 is mounted on the lifting shaft 4-5. The lower end face of the return spring 4-6 is fixedly connected to the inner bottom of the groove 1. The lower end face of the lifting shaft 4-5 extends out of the groove 1. A driving inclined surface 4-7 is provided on the lower end face of the lifting shaft 4-5. A push rod 5 is provided at the bottom of the groove 1. A friction inclined surface 6 is provided at the end of the push rod 5. The friction inclined surface 6 is in contact with the driving inclined surface 4-7.

[0030] In some examples, the drive sealing assembly 4 also includes a lifting shaft 4-5, which is mounted on the lower end face of the sealing ball 4-4 and the two can be fixedly connected. A return spring 4-6 is fitted on the lifting shaft 4-5, and the lower end face of the return spring 4-6 is fixedly connected to the inner bottom of the groove 1. The lower end face of the lifting shaft 4-5 extends out of the groove 1, and a drive ramp 4-7 is provided on the lower end face of the lifting shaft 4-5. At the same time, a push rod 5 is installed at the bottom of the groove 1, and a friction ramp 6 is provided at the end of the push rod 5. The friction ramp 6 is in contact with the drive ramp 4-7. When the push rod 5 is pushed, friction occurs. The interaction between the wiping inclined surface 6 and the driving inclined surface 4-7 can drive the lifting shaft 4-5 to move up and down, thereby causing the sealing ball 4-4 to slide within the clearance groove 4-3, thus achieving the sealing or opening of the lower end of the collecting cone cover 3-3. When the push rod 5 is released, under the action of the return spring 4-6, the lifting shaft 4-5 and the sealing ball 4-4 can return to their original positions. Through the coordinated work of the above components, the insulating mesh used in the electrolytic cell can achieve effective filtration of liquids, collection of specific substances, and flexible sealing and opening of related channels, meeting the insulation and material handling requirements of the electrolytic cell during operation.

[0031] For example, such as Figure 3 As shown, the outer wall of the tank 1 is provided with a liquid inlet chamber 7, and the inside of the liquid inlet chamber 7 is provided with a liquid inlet hole 8, and a liquid inlet pipe 9 is connected to the liquid inlet hole 8.

[0032] In some examples, an inlet chamber 7 is provided on the outer wall of the tank 1, and an inlet hole 8 is provided inside the inlet chamber 7. An inlet pipe 9 is connected to the inlet hole 8, and the liquid to be treated can be introduced into the tank 1 through the inlet pipe 9.

[0033] For example, such as Figure 3 As shown, it includes a reinforcing frame 10; The reinforcing frame 10 is installed on the inner side wall of the support frame 2. One end of the reinforcing frame 10 is fixedly connected to the bottom surface of the trough 1. The bottom surface of the reinforcing frame 10 is provided with a support column 11.

[0034] In some examples, to further enhance the stability of the overall structure, a reinforcing frame 10 is provided on the inner wall of the support frame 2. One end of the reinforcing frame 10 is fixedly connected to the bottom surface of the tank 1, for example, by welding, to ensure a firm connection. At the same time, a supporting column 11 is installed on the bottom surface of the reinforcing frame 10, and the lower end face of the supporting column 11 matches the height of the lower end face of the support frame 2. This allows the entire device to be placed stably on the ground or workbench. The insulating collection assembly 3 is installed inside the tank 1. Its core component is the insulating filter screen 3-1, which is made of a material with good insulation properties, such as polytetrafluoroethylene. It can filter the liquid entering the tank 1.

[0035] For example, such as Figure 3 As shown, the lower end face of the support column 11 is at the same height as the lower end face of the support frame 2.

[0036] During operation, the insulating mesh used in the electrolytic cell works on the synergistic effect of filtration separation, directional flow guidance, and controlled blocking, as detailed below: 1. Liquid introduction and preliminary filtration: The liquid to be treated enters the inlet chamber 7 through the inlet pipe 9 on the outer wall of the tank 1, and then flows into the interior of the tank 1 through the inlet hole 8. The liquid first comes into contact with the insulating filter screen 3-1, which uses its insulating properties (to avoid current interference during the electrolysis process) and filtration function to intercept solid impurities or specific particles in the liquid, thus achieving preliminary purification.

[0037] 2. Directional Flow Guidance and High-Efficiency Collection: The filter port 3-2 on the insulating filter screen 3-1 works in conjunction with the collection cone hood 3-3 to guide the filtered target liquid (such as precipitates generated by electrolysis or specific reactants) into the cone hood. At the same time, the drive shaft 3-5 drives the flow-deflecting plate 3-6 and the flow-deflecting vane 3-7 to rotate, stirring the liquid to form a directional flow and accelerating the accumulation of the target substance into the collection cone hood. The linkage shaft 3-8 synchronously drives the deflecting vane to rotate, further enhancing the liquid flow and improving the collection efficiency.

[0038] 3. Controllable switching between blocking and emission Blocking state: The reset spring 4-6 extends naturally, pushing the lifting shaft 4-5 to move upward, so that the blocking ball 4-4 fits tightly with the lower end of the collecting cone 3-3 to form a seal. At this time, the collected material is temporarily stored in the cone 3-3.

[0039] Discharge status: Pushing the push rod 5 causes the friction inclined surface 6 at its end to interact with the driving inclined surface 4-7 of the lifting shaft 4-5, forcing the lifting shaft 4-5 to move downward against the elastic force of the return spring 4-6. This causes the sealing ball 4-4 to slide down along the clearance groove 4-3 of the fixed frame 4-2, opening the outlet of the collecting cone cover 3-3 and allowing the collected material to be discharged. After releasing the push rod 5, the return spring 4-6 resets, and the sealing is achieved again.

[0040] 4. Structural stability assurance The support frame 2, the reinforcing frame 10, and the support column 11 together form a stable load-bearing structure, ensuring that the tank 1 remains stable under liquid pressure and component operation, and avoiding the impact of vibration or deformation on the filtration and collection effect.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
