Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1-4 ;
[0025] An electrolysis device for sodium chlorate production includes an electrolysis tank 1. The electrolysis tank 1 serves as the core container for the electrolysis reaction in sodium chlorate production, providing a closed and stable reaction space for the electrolysis process and ensuring that the reaction takes place in a controllable environment. The top of the electrolysis tank 1 is sealed with a top cover 11 by bolts. The top cover 11 can prevent material leakage or the entry of external impurities during the electrolysis process, and it is also convenient to open it for maintenance and repair of the internal components. The electrolysis tank 1 is equipped with a cleaning mechanism 2, which facilitates the cleaning of the inside of the electrolysis tank 1 for sodium chlorate production.
[0026] The cleaning mechanism 2 includes a guide trough 22, a feeding and discharging assembly 28, and a cleaning assembly 29. The guide trough 22 is opened on the inner wall of the electrolytic tank 1 and the top cover 11. The guide trough 22 provides a sliding track for the guide block 232. The feeding and discharging assembly 28 is set on the electrolytic tank 1 and the top cover 11. The cleaning assembly 29 is set inside the electrolytic tank 1.
[0027] Furthermore, the cleaning assembly 29 includes a first screw 21 and a second screw 211. The first screw 21 and the second screw 211 are rotatably mounted inside both ends of the electrolytic tank 1, respectively. The threads of the first screw 21 and the second screw 211 are opposite. The connections between the first screw 21 and the second screw 211 and the electrolytic tank 1 are sealed to prevent leakage. The first screw 21 and the second screw 211 rotate under the drive of the reduction motor 27, causing the first electrode plate 23 and the second electrode plate 24 to move in opposite directions in a linear motion, adjusting the distance between the first electrode plate 23 and the second electrode plate 24. A first scraper 25 is fixedly mounted on the other end of the first screw 21 and the second screw 211. The first scraper 25 rotates with the first screw 21 and the second screw 211. The end of the first scraper 25 is not only used to scrape sodium chlorate crystals or impurities from specific areas of the inner wall of the electrolytic tank 1, but also for... The first electrode plate 23, the second electrode plate 24, the first cleaning frame 231, and the second cleaning frame 241 are cleaned on one side to prevent sodium chlorate crystals or impurities from adhering to the first electrode plate 23 and the second electrode plate 24 and affecting the electrolysis reaction. The first electrode plate 23 is threaded on the first screw 21 and serves as an electrode for the electrolysis reaction, participating in the electrolysis process of sodium chlorate production. At the same time, as the first screw 21 moves, it drives the first cleaning frame 231 to move synchronously. The first cleaning frame 231 is fixedly installed on the side of the first electrode plate 23. The first cleaning frame 231 moves with the first electrode plate 23 to scrape and clean the inner wall area of the electrolysis tank 1 to reduce material residue. A guide block 232 is fixedly provided on the side of the first cleaning frame 231. The guide block 232 is slidably disposed in the guide groove 22. The corresponding guide block 232 moves to guide the first electrode plate 23 and the second electrode plate 24.
[0028] Furthermore, a second electrode plate 24 is threaded onto the second screw 211. The second electrode plate 24, together with the first electrode plate 23, forms an electrolytic circuit and participates in the electrolytic reaction. As the second screw 211 moves, it drives the second cleaning frame 241 to move. The second cleaning frame 241 is fixedly installed on the side of the second electrode plate 24. The second cleaning frame 241 moves with the second electrode plate 24, assisting in cleaning the inner wall area of the electrolytic tank 1. It forms a synergistic cleaning effect with the first cleaning frame 231, improving the cleaning coverage area inside the tank. A guide block 232 is also fixedly installed on the side of the second cleaning frame 241. A second scraper 26 is fixedly installed at one end of the first screw 21. The second scraper 26 moves with the first screw 21. The first screw 21 rotates, not only to clean the inner wall of one end of the electrolytic tank 1, but also to scrape and clean sodium chlorate crystals or impurities on the other side of the first electrode plate 23 and the first cleaning frame 231. A third scraper 261 is fixedly installed at one end of the second screw 211. The third scraper 261 rotates with the second screw 211, and is used not only to clean the inner wall of the other end of the electrolytic tank 1, but also to scrape and clean sodium chlorate crystals or impurities on the other side of the second electrode plate 24 and the second cleaning frame 241. A geared motor 27 and a distribution box 12 are installed at one end of the electrolytic tank 1. The output end of the geared motor 27 is connected to the first screw 21, and the geared motor 27 is electrically connected to the distribution box 12.
[0029] Furthermore, the feeding and discharging assembly 28 includes a feed pipe 281, a first inlet pipe 282, and a second inlet pipe 283. The feed pipe 281, first inlet pipe 282, and second inlet pipe 283 are respectively installed on the top of the top cover 11. The feed pipe 281 is used to transport the raw materials required for sodium chlorate production into the electrolytic tank 1. The first inlet pipe 282 and second inlet pipe 283 facilitate the wiring of the first electrode plate 23 and the second electrode plate 24. A first valve 284 is installed at the bottom of one end of the electrolytic tank 1, a third valve 286 is installed at the bottom of the other end of the electrolytic tank 1, and a second valve 285 is installed at the bottom of the middle of the electrolytic tank 1. The first valve 284, the third valve 286, and the second valve 285 not only increase the discharge rate but also prevent residual liquid from remaining inside the electrolytic tank 1.
[0030] The working principle of this utility model is as follows: In the sodium chlorate production process, the electrolytic tank 1 serves as the core reaction vessel, providing a closed and stable space for the electrolytic reaction. The top cover 11 is installed on the top of the electrolytic tank 1 with bolts to ensure that the reaction takes place in a controllable environment, preventing material leakage or the entry of external impurities, and facilitating the maintenance and repair of the components inside the tank later. During the electrolytic reaction, the raw materials required for production are transported into the electrolytic tank 1 through the feed pipe 281. The first electrode plate 23 and the second electrode plate 24 are wired through the first inlet pipe 282 and the second inlet pipe 283, respectively. The two work together to form an electrolytic circuit and participate in the electrolytic process of sodium chlorate production.
[0031] When it is necessary to adjust the electrode plate spacing to optimize the electrolysis reaction, the first screw 21 is driven to rotate by the geared motor 27. Since the first screw 21 and the second screw 211 have opposite threads and rotate synchronously, the first electrode plate 23 with threads installed on the first screw 21 and the second electrode plate 24 with threads installed on the second screw 211 move in opposite or opposite linear directions. During this process, the first cleaning frame 231 on the side of the first electrode plate 23 and the second cleaning frame 241 on the side of the second electrode plate 24 move synchronously with the electrode plates, and the guide blocks 232 on the sides of the first cleaning frame 231 and the second cleaning frame 241 slide along the guide groove 22 to guide the movement of the electrode plates and ensure the smoothness of the movement.
[0032] During and after electrolysis, if it is necessary to clean sodium chlorate crystals or impurities inside the tank, when the first screw 21 and the second screw 211 rotate, the first scraper 25 fixedly installed at their ends rotates together. This not only scrapes away crystals or impurities from specific areas of the inner wall of the electrolysis tank 1, but also cleans one side of the first electrode plate 23, the second electrode plate 24, the first cleaning frame 231, and the second cleaning frame 241. Simultaneously, the first cleaning frame 231 and the second cleaning frame 241 scrape and clean the inner wall area of the electrolysis tank 1 during their movement, reducing material residue and creating a synergistic cleaning effect, increasing the clean coverage area inside the tank, and adjusting the position of the first electrode plate 23. The second scraper 26 rotates with the first screw 21, which can scrape and clean the inner wall of one end of the electrolytic tank 1 and the other side of the first electrode plate 23 and the first cleaning frame 231. Adjust the position of the first cleaning frame 231. The third scraper 261 rotates with the second screw 211, which can scrape and clean the inner wall of the other end of the electrolytic tank 1 and the other side of the second electrode plate 24 and the second cleaning frame 241. When it is necessary to discharge the material and cleaning liquid in the electrolytic tank 1, open the first valve 284 at the bottom of one end of the electrolytic tank 1, the third valve 286 at the bottom of the other end, and the second valve 285 at the bottom of the middle. The discharge rate is increased by coordinating multiple valves, while preventing residual liquid in the tank.
[0033] In summary, by setting up a cleaning mechanism inside the electrolytic tank for sodium chlorate production, not only can crystals and trace impurities on the electrode plates be removed in a coordinated manner, but also crystals and trace impurities on the inner wall of the electrolytic tank can be removed, facilitating the cleaning of the inside of the electrolytic tank; moreover, the device can optimize the spacing between the two electrode plates according to the raw material concentration and reaction stage, ensuring that the current density and ion migration efficiency are at their optimal state during the electrolysis process.
