[0033] A positive electrode frame for sodium persulfate micro-etching solution electrolytic reuse, comprising a frame body 1, two ion membranes 3 and two outer baffles 4.
[0034] The frame body 1 is provided with an opening 11 on each of the left and right sides, and is provided with a mounting opening 12 on the top, the opening 11 and the mounting opening 12 are communicated with the inside of the frame body 1, and the mounting opening 12 is used for mounting a positive electrode;
[0035] The frame body 1 is provided with an ion membrane 3 and an outer baffle 4 on each side, and the ion membrane 3 and the outer baffle 4 are sequentially arranged from inside to outside, and cover the opening 11.
[0036] The outer baffle 4 is provided with a plurality of outer baffle openings 40, and the plurality of outer baffle openings 40 are formed by a plurality of longitudinal plates 41 and a plurality of transverse plates 42.
[0037] The utility model provides a kind of positive electrode frame for sodium persulfate micro-etching solution electrolytic recycling. The positive electrode frame includes frame body 1, two ion membranes 3 and two outer baffles 4. The frame body 1 is provided with an opening 11 on each of the left and right sides, and is provided with a mounting opening 12 on the top, the opening 11 and the mounting opening 12 are communicated with the inside of the frame body 1, and the mounting opening 12 is used for mounting a positive electrode in the inside of frame body 1. The frame body 1 is provided with an ion membrane 3 and an outer baffle 4 on each side, and the ion membrane 3 and the outer baffle 4 are sequentially arranged from inside to outside and cover the opening 11; the ion membrane 3 is used for isolating the reaction solution in the inside of frame body 1 from the negative electrode outside frame body 1; the outer baffle 4 is formed by a plurality of longitudinal plates 41 and a plurality of transverse plates 42 to form a plurality of outer baffle openings 40, and the outer baffle opening 40 provides an effective path for electrolytic reaction between the positive and negative electrodes, and the longitudinal plate 41 and the transverse plate 42 effectively limit the degree of bulging of the ion membrane 3.
[0038] Compared with the traditional single diaphragm positive electrode frame design, the multi-layer structure of the utility model has obvious advantages. First, it can more effectively prevent the sodium persulfate in the positive electrode frame from easily consuming the elemental copper deposited on the negative electrode, affecting the electrolysis efficiency; second, the design of multiple outer baffle openings 40 on the outer baffle solves the problem of liquid level difference between the inside and outside of the frame, and the bulging of the ion membrane 3 is limited by the longitudinal plate 41 and the transverse plate 42, further avoiding the influence of the reaction solution inside and outside the frame on the positive and negative electrodes, which is conducive to maintaining the stable progress of electrolytic reaction.
[0039] Further, it also includes two inner baffles 2, and an inner baffle 2 is arranged between the frame body 1 and the ion membrane 3 on the same side.
[0040] The inner baffle 2 is provided with a plurality of inner baffle openings 20, and the inner baffle opening 20 corresponds to the outer baffle 40.
[0041] Two inner separators 2 are added, and by placing one inner separator 2 between the frame 1 and the ion exchange membrane 3, the structural stability of the positive electrode frame can be further enhanced. Similarly, the inner separator 2 is provided with inner separator openings 20 corresponding to the outer separator openings 40, which helps to ensure the reaction area (pathway) of the electrolysis reaction and ensures the electrolysis efficiency.
[0042] Further explanation, the role of the outer separator 4 is to avoid the case where the liquid level inside the frame is higher than the liquid level outside the frame, and the high-low liquid level difference causes the ion exchange membrane 3 to expand and bulge outward, contacting the negative electrode and affecting electrolysis. The role of the inner separator 2 is to avoid the case where the liquid level outside the frame is higher than the liquid level inside the frame, and the high-low liquid level difference causes the ion exchange membrane to shrink inward (bulge inward), contact the positive electrode, and affect electrolysis.
[0043] This embodiment effectively improves the structural stability and electrolysis efficiency of the positive electrode frame through the design of multiple layers of isolation structure and openings. Compared with traditional design, it can better prevent the ion exchange membrane from bulging, ensure the safety and effectiveness of the electrolysis process, and thus improve the reliability and production efficiency of the entire electrolysis system.
[0044] Furthermore, the inner separator 2 and the frame 1 are provided with an inner gasket 51, and the outer separator 4 and the ion exchange membrane 3 are provided with an outer gasket 52.
[0045] The inner gasket 51 and the outer gasket 52 are respectively located between the inner separator 2 and the frame 1, and between the outer separator 4 and the ion exchange membrane 3. Their role is to provide important sealing effect, prevent liquid leakage, and improve the stability and efficiency of the electrolysis process. By setting gaskets at these key connection parts, good sealing between components is ensured, leakage of electrolyte is avoided, and the reliability of the device during use is ensured.
[0046] The gasket can be made of a variety of different materials and structures. For example, the inner gasket 51 and the outer gasket 52 can be made of rubber materials with good corrosion resistance, such as fluororubber, silicone, etc., to ensure their stable performance in long-term sodium persulfate environment. In addition, the shape and size of the gasket can also be designed according to the specific sealing requirements, such as O-ring, flat gasket, etc., to meet the sealing needs in different environments. To further enhance the sealing effect, the surface of the gasket can be designed with concave-convex texture to increase the contact area with the inner separator 2, the frame 1, the outer separator 4 and the ion exchange membrane 3, thereby improving the sealing performance.
[0047] Furthermore, the two outer separators 4 and the frame 1 are connected by several titanium screws 6.
[0048] Titanium screws 6 are used to firmly connect the two outer partitions 4 and the assembly between the outer partitions 4 and the frame 1 to the frame 1, and the titanium screws 6 have excellent corrosion resistance and mechanical strength, making the connection more stable and durable. Through this installation method, it can effectively prevent the anode frame from loosening or falling off due to external force or electrolyte corrosion during use, thereby ensuring the stable operation of the equipment and prolonging the service life. The use of titanium screws 6 not only improves the structural strength of the positive electrode frame, but also enhances the reliability of the assembly in harsh working environments, ensuring that the equipment can operate continuously and efficiently during the sodium persulfate micro-etching electrolyte recycling process.
[0049] Further, the lower part of the front end of the frame 1 is provided with a liquid inlet 13, which communicates with the inside of the frame 1;
[0050] The upper part of the rear end of the frame 1 is provided with an overflow port 14, which communicates with the inside of the frame 1.
[0051] By setting the liquid inlet 13 at the lower part of the front end of the frame 1 and the overflow port 14 at the upper part of the rear end, the effective flow and uniform distribution of the electrolyte are ensured, thereby improving the electrolysis effect and efficiency. The liquid inlet 13 is located at the lower part of the front end of the frame 1 to introduce the electrolyte into the frame 1, while the overflow port 14 is located at the upper part of the rear end of the frame 1 to discharge the electrolyte, ensuring the circulation of the positive electrode reaction liquid. This design makes the electrolyte flow from bottom to top inside the frame, realizing the effective flow and uniform distribution of the electrolyte, thereby ensuring the stability and efficiency of the electrolysis process.
[0052] Further, the outer side of the front end of the frame 1 is provided with a liquid guide pipe 7;
[0053] The liquid guide pipe 7 is arranged along the height direction of the frame 1, one end of the liquid guide pipe 7 is connected with the liquid inlet 13, and the other end of the liquid guide pipe 7 is located at the upper part of the front end of the frame 1.
[0054] The liquid guide pipe 7 is arranged along the height direction of the frame 1, one end of the liquid guide pipe 7 is connected with the liquid inlet 13 at the lower part, and the other end at the upper part can be connected with the circulating mechanism for realizing the liquid circulation inside and outside the frame. By changing the actual liquid inlet from the lower part to the upper part through the liquid guide pipe 7, it can be convenient for the actual application that the anode frame and the cathode plate are placed in the reaction tank with a certain interval, and it is difficult to input the positive electrode reaction liquid into the frame from the lower part of the anode frame. Therefore, by setting the vertically extending liquid guide pipe 7 outside the frame 1, it is convenient to input the reaction liquid into the frame 1.
[0055] Further, the upper part of the front end of the frame 1 is provided with a clamping jaw 15, which is used to clamp the liquid guide pipe 7.
[0056] By setting the clamping jaw 15 on the front end upper part of the frame body 1, this design can firmly clamp the liquid guide pipe 7, so that it remains stable during use, thereby preventing the liquid guide pipe 7 from being displaced or falling off due to external force or other factors. The cooperation of the clamping jaw 15 and the liquid guide pipe 7 ensures the fixation and stability of the liquid guide pipe 7, which helps to improve the reliability and durability of the entire positive frame device. The clamping jaw 15 can be implemented in various ways, such as hooks, grooves, clamps, etc., and the material of the clamping jaw 15 can be selected from materials with excellent corrosion resistance to ensure its long-term stability in the sodium persulfate micro-etching solution environment. In specific implementation, the clamping jaw 15 is set to match the outer diameter of the liquid guide pipe 7 to ensure that the clamping jaw can tightly wrap the liquid guide pipe and achieve stable fixation.
[0057] Further, the positions of the outer baffle openings 40 and the inner baffle openings 20 correspond to the positions of the electrode sheets of the positive electrode.
[0058] By corresponding the positions of the outer baffle openings 40 and the inner baffle openings 20 to the positions of the electrode sheets of the positive electrode, the effective electric field of the electrode sheets of the positive electrode radiated to the cathode plate during electrolysis can be ensured, thereby improving the electrolysis efficiency. At the same time, this design can ensure the full utilization of the electrode sheets and avoid the problem of uneven distribution of electrolyte on the surface of the electrode sheets, thereby further improving the overall performance of the electrolysis device.
[0059] Further, the total area of the plurality of outer baffle openings 40 accounts for 60%-80% of the total area of the outer baffle 4.
[0060] The total area of the plurality of inner baffle openings 20 accounts for 60%-90% of the total area of the inner baffle 2.
[0061] The opening area of the outer baffle openings 40 and the inner baffle openings 20 ensures the electric field area of the positive electrode radiated to the cathode. Therefore, by ensuring the reaction area of the electrolysis reaction, the electrolysis efficiency can be further improved.
[0062] The technical principles of the present utility model are described above in combination with specific embodiments. These descriptions are only to explain the principles of the present utility model, and cannot be interpreted in any way as a limitation on the protection scope of the present utility model. Based on the above explanation, those skilled in the art can think of other specific embodiments of the present utility model without creative labor, and these embodiments will fall within the protection scope of the present utility model.
