[0002] Titanium dioxide is an active electrode material with very good blackness. Titanium dioxide can protect the two poles of the battery and is used as a bipolar battery material and LED black matrix material. Through titanium dioxide modification, titanium dioxide has a smaller particle size and higher covering power. The Ti4O7 anode has low resistivity, stable chemical properties, good corrosion resistance, good conductivity, and can pass large currents. It has a three-dimensional structural coating, which greatly improves the bonding strength of the coating.

[0003] In the prior art, sodium perchlorate is electrolyzed to produce an integrated Ti4O7 anode, which outputs electrical energy through a conductive plate. However, the integrated Ti4O7 anode will expand thermally and absorb expansion during use, causing the entire anode to swell, thereby causing the anode plate to break, thereby reducing the service life of the anode plate.

[0004] Therefore, it is necessary to invent an integrated Ti4O7 anode for the production of sodium perchlorate by electrolysis to solve the above problems. Utility Model Content

[0005] The utility model aims to provide an integrated Ti4O7 anode for the production of sodium perchlorate by electrolysis, so as to solve the problem that the integrated Ti4O7 anode outputs electric energy through a conductive plate, but the integrated Ti4O7 anode will expand thermally and absorb expansion during use, resulting in overall expansion and bulging, thereby causing the anode plate to break, thereby reducing the service life of the anode plate.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an integrated Ti4O7 anode for the production of sodium perchlorate by electrolysis, comprising an anode body, wherein the anode body is provided with a plurality of anode bodies, a connecting plate is fixedly connected to the top of the anode body, and a conductive column is fixedly connected to the top of the connecting plate;

[0007] A plurality of square grooves are provided on both sides of the connecting plate, and a clamping assembly is arranged inside the plurality of square grooves. The clamping assembly includes a fixing seat, and the fixing seat is fixedly connected to the square groove. A fixing groove is provided inside the fixing seat, and a moving rod is slidably connected inside the fixing groove. A spring is provided on one side of the moving rod, and two ends of the spring are respectively fixedly connected to the fixing groove and the moving rod. Two fixing blocks are fixedly connected to the outer ring of the moving rod, a connecting block is fixedly connected to the bottom of the moving rod, and a partition is fixedly connected to the bottom of the connecting block.

[0008] Preferably, two elastic sheets are fixedly connected to the outer ring of the fixing seat, and a push rod is fixedly connected to the inside of the two elastic sheets. The push rod passes through the inside of the fixing seat and extends into the fixing seat.

[0009] Preferably, the plurality of anode bodies are distributed in a linear array.

[0010] Preferably, the separator is located between two anode bodies.

[0011] Preferably, one end of the push rod and the fixing block are both triangular, and the push rod and the fixing block fit each other.

[0012] Preferably, both sides of the anode body are sleeved with insulating buckles, and the insulating buckles are respectively fitted with the bottom of the connecting plate and the top of the connecting block.

[0013] Preferably, the insulating buckle is U-shaped.

[0014] Technical effects and advantages of the utility model:

[0015] 1. The utility model is provided with a clamping assembly, which helps to install the insulating clip between the two anode bodies. When the anode body is in use, on the one hand, the insulating clip can limit the vertical movement of the partition, so that the partition is located between the two anode bodies and fits each other. On the other hand, the insulating clip and the partition cooperate with each other to avoid thermal expansion or overall expansion and bulging of the anode body, thereby increasing the service life of the Ti4O7 anode.

[0016] 2. Furthermore, considering that the insulating buckle needs to be replaced after long-term use, if the replacement process is cumbersome, it will affect its performance and reduce the practicality of the insulating buckle. Therefore, a fixed block is provided in the utility model. When the moving rod is forced to move vertically downward, a space for installing the insulating buckle is generated between the connecting block and the square groove for installing the insulating buckle. At the same time, when the moving rod moves downward, the push rod will move along the inclined surface of the fixed block to shrink the elastic sheet, thereby increasing the gap between the elastic sheet and the square groove, which is convenient for the installation and disassembly of the insulating buckle.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-Figure 3 As shown, the integrated Ti4O7 anode for the production of sodium perchlorate by electrolysis comprises an anode body 1, wherein a plurality of anode bodies 1 are provided, and the plurality of anode bodies 1 are distributed in a linear array, a connecting plate 2 is fixedly connected to the top of the anode body 1, a conductive column 3 is fixedly connected to the top of the connecting plate 2, and insulating buckles 9 are sleeved on both sides of the anode body 1, and the insulating buckles 9 are U-shaped, and the insulating buckles 9 are respectively fitted with the bottom of the connecting plate 2 and the top of the connecting block 7.

[0023] The principle of electrolytic sodium perchlorate:

[0024] The electrolytic process of producing sodium perchlorate mainly consists of an electrolytic cell and a power supply. The electrolytic cell is usually made of titanium or polymer materials to prevent corrosion from sodium ions. The power supply provides current to enable the reaction to proceed.

[0025] The electrolyte in the electrolytic cell is the key to the production of sodium perchlorate. Generally speaking, the electrolyte is composed of sodium chloride and sulfuric acid. Sodium chloride is the main raw material, while sulfuric acid plays a role in adjusting the pH of the electrolyte. The electrolyte in the electrolytic cell needs to maintain a certain concentration and temperature to ensure the smooth progress of the reaction.

[0026] During the electrolysis process, the positive electrode in the electrolytic cell is the anode and the negative electrode is the cathode. The chloride ions on the positive electrode will be affected by the current on the anode, causing a chlorination reaction to produce chlorine gas. At the same time, the water molecules on the negative electrode will be reduced to hydrogen and hydroxide ions. Chlorine and hydrogen are physically separated during electrolysis and further purified.

[0027] After the chlorine element is generated, it reacts with the hydroxide ions in the electrolyte to generate hypochlorous acid. Hypochlorous acid further decomposes to generate perchloric acid and sodium chloride. The reaction process needs to be precisely controlled because a certain current, temperature and concentration need to be controlled during the reaction, and impurities in the electrolyte need to be prevented from entering the final product.

[0028] The integrated Ti4O7 anode in this application will be produced and prepared according to the above steps.

[0029] A plurality of square grooves 4 are provided on both sides of the connecting plate 2, and the plurality of square grooves 4 are distributed in a linear array. A clamping assembly is arranged inside the plurality of square grooves 4, and the clamping assembly includes a fixing seat 5, and the fixing seat 5 is fixedly connected to the square groove 4. A fixing groove 10 is provided inside the fixing seat 5, and a moving rod 11 is slidably connected inside the fixing groove 10. A spring 12 is provided on one side of the moving rod 11, and both ends of the spring 12 are respectively fixedly connected to the fixing groove 10 and the moving rod 11. Two fixing blocks 13 are fixedly connected to the outer circle of the moving rod 11, and a connecting block 7 is fixedly connected to the bottom of the moving rod 11, and a partition 8 is fixedly connected to the bottom of the connecting block 7, and the partition 8 is located between the two anode bodies 1.

[0030] The separator 8 is made of insulating material and has good insulation properties, and can also prevent the Ti4O7 anode from expanding.

[0031] The moving rod 11 is T-shaped, and the diameter of the upper part of the moving rod 11 is larger than the diameter of the lower part.

[0032] Two elastic sheets 6 are fixedly connected to the outer ring of the fixed seat 5, and a push rod 14 is fixedly connected to the inside of the two elastic sheets 6. One end of the push rod 14 and the fixed block 13 are both triangular. The push rod 14 and the fixed block 13 fit each other. The push rod 14 runs through the inside of the fixed seat 5 and extends into the fixed seat 5.

[0033] The elastic sheet 6 is made of insulating material, is arc-shaped, and has a certain elasticity.

[0034] The utility model is provided with a clamping assembly, which helps to install the insulating clip 9 between the two anode bodies 1. When the anode body 1 is in use, on the one hand, the insulating clip 9 can limit the vertical movement of the partition 8, so that the partition 8 is located between the two anode bodies 1 and fits each other. On the other hand, the insulating clip 9 cooperates with the partition 8 to avoid thermal expansion or overall expansion and bulging of the anode body 1, thereby increasing the service life of the Ti4O7 anode.

[0035] Furthermore, considering that the insulating buckle 9 needs to be replaced after long-term use, if the replacement process is cumbersome, it will affect its performance and reduce the practicality of the insulating buckle 9. Therefore, a fixed block 13 is provided in the utility model. When the moving rod 11 is forced to move vertically downward, a space for installing the insulating buckle 9 is generated between the connecting block 7 and the square groove 4, which is used to install the insulating buckle 9. At the same time, when the moving rod 11 moves downward, the push rod 14 will move along the inclined surface of the fixed block 13 to shrink the elastic sheet 6, thereby increasing the gap between the elastic sheet 6 and the square groove 4, and facilitating the installation and disassembly of the insulating buckle 9.

[0036] Furthermore, the clamping assembly can prevent the anode body 1 from thermal expansion or overall expansion and bulging. Specifically, first hold the connecting block 7, and when subjected to force, the connecting block 7 moves vertically downward, the moving rod 11 moves vertically downward following the direction of the connecting block 7, the fixed block 13 moves vertically downward following the direction of the moving rod 11, and the push block 14 moves horizontally under force, and the elastic sheet 6 performs a reset movement without external force. At this time, hold the insulating buckle 9 again, put the insulating buckle 9 on the anode body 1, and then release the connecting block 7. Under the elastic force of the spring 12, the insulating buckle 9 is restricted on the anode body 1.
