Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell technology, specifically to a descaling device for electrolytic cells with circulating filtration. Background Technology

[0002] Electrolytic cells are core reaction equipment in industries such as chemical, metallurgical, and water treatment. They achieve material transformation or purification through electrochemical reactions of electrolyte solutions. During long-term operation, calcium and magnesium ions in the electrolyte react with hydroxide and carbonate ions to form insoluble salts such as calcium carbonate and magnesium hydroxide. At the same time, metal oxides and impurity particles generated by electrode reactions gradually deposit on the tank walls, electrode surfaces, and flow channels, forming a stubborn scale layer. Therefore, electrolytic cell descaling devices are needed to achieve the descaling function. However, existing electrolytic cell descaling devices still have certain defects in use. As proposed in application number CN201922473801.0, an electrolytic cell descaling device for denture processing includes an electrolytic cell body, a receiving tank, and a liquid outlet. The receiving tank is located at the middle of the inner surface of the electrolytic cell body, and a mounting float is installed through the outer side of the receiving tank. A limiting roller is rotatably connected to the inner side of the mounting float, and the limiting roller is connected to the inner surface of the receiving tank. A first pull rope is fixedly connected to the outer end of the mounting float, and the first pull rope is connected to the inner surface of the electrolytic cell body. A liquid outlet is located at the lower end of the electrolytic cell body. The outer end of the body has a first sliding groove. As the electrolyte inside the electrolytic cell body is discharged, the water level continuously drops. The "C"-shaped first scraper, which is connected to the lowered installation float by a pull rope, will slide synchronously along the inner surface of the electrolytic cell body, thereby cleaning and descaling the inner surface of the attached electrolytic cell body. In actual use, the cleaning power is insufficient when scraping the dirt on the inner wall by only using the pull rope and scraper. When the dirt is stubborn and not easily scraped off, it will block the movement of the scraper, thus reducing the descaling effect.

[0003] Therefore, we propose a circulating filtration electrolytic cell descaling device to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a circulating filtration electrolytic cell descaling device to solve the problem of insufficient cleaning power mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a descaling device for an electrolytic cell with circulating filtration, comprising a tank body, wherein support plates are symmetrically installed at the bottom of the tank body for support, and an internal descaling mechanism is installed inside the tank body to scrape off dirt from the inner wall of the tank body. A circulation box is fixedly installed on the front and rear sides of the tank, and a filter plate is installed inside the circulation box; The circulation tank is equipped with circulation filtration mechanisms at both ends and the bottom to circulate and filter the cleaning solution.

[0006] Preferably, the internal descaling mechanism includes a lifting scraper that slides and fits against the inner ring of the tank. A connecting frame is fixedly installed in the middle of the lifting scraper. The connecting frame is arranged in an "X" shape. A first cylinder is fixedly installed at the bottom of the tank. The shaft end of the first cylinder is fixedly connected to the center of the connecting frame. Limiting frames are symmetrically installed at the top of the left and right ends of the lifting scraper. The limiting frames are slidably connected to the tank.

[0007] Preferably, the internal descaling mechanism further includes a sliding scraper fitted into the bottom inner side of the left and right ends of the tank body. A second cylinder is fixedly installed in the middle of the left and right ends of the tank body. The shaft end of the second cylinder is fixedly connected to the sliding scraper. When the sliding scraper retracts, the inner wall surface is parallel to the inner wall surface of the left and right ends of the tank body.

[0008] With the above-mentioned structural design, the "X"-shaped connecting frame can evenly transmit the driving force of the first cylinder to the lifting scraper, ensuring that the lifting scraper and the inner wall of the tank always maintain a stable sliding contact state, avoiding scraper deviation and missed scraping due to uneven force. After the cleaning liquid softens the dirt on the inner wall of the tank, the first cylinder drives the lifting scraper to move back and forth along the height direction of the tank, which can directly scrape off the softened stubborn dirt, solving the problem of "poor contact and incomplete descaling" in traditional mechanical descaling. The through sliding cooperation between the limiting frame and the tank can limit the movement trajectory of the lifting scraper, prevent the scraper from tilting or jamming during the lifting process, and ensure the continuity of the descaling action. The second cylinder drives the horizontal reciprocating scraper to thoroughly remove the dirt deposited at the bottom of the left and right ends of the tank, making up for the shortcomings of the lifting scraper in cleaning the "corner areas". When the horizontal scraper retracts, the inner wall surface is parallel to the inner wall surface of the left and right ends of the tank, which will not hinder the lifting scraper's upward and downward movement, nor will it affect the softening effect of the cleaning liquid in the tank.

[0009] Preferably, the circulation box is fixedly connected to the filter plate.

[0010] The above-mentioned structural design prevents the filter plate from shifting due to the impact of the cleaning liquid, ensuring stable filtration, uniform filtration of the cleaning liquid, and minimal impurities in the cleaning liquid circulating back into the tank. This does not affect the softening of dirt, meets the requirements for the recycling of cleaning liquid, and indirectly improves cleaning power.

[0011] Preferably, the circulating filtration mechanism includes output pumps installed at equal intervals at the bottom of the circulating tank. The inlet end of the output pump is connected to the bottom of the circulating tank, and the outlet end of the output pump is fixedly connected to an outlet pipe, which is connected to the bottom of the tank.

[0012] Preferably, the circulating filtration mechanism further includes a circulating pump fixedly installed on the left and right ends of the circulating tank. The inlet end of the circulating pump is fixedly connected to an inlet pipe, the bottom end of which is connected to the bottom of both ends of the circulating tank. The outlet end of the circulating pump is fixedly connected to a connecting pipe, the outlet end of which is connected to the top of both ends of the circulating tank.

[0013] With the above-described structure, after the cleaning solution softens the dirt in the tank and mixes with the scraped dirt particles, the output pump can deliver the cleaning solution into the circulation tank, where it is filtered by the filter plate and stored for the next cleaning cycle. This prevents the cleaning solution from becoming less effective at softening dirt due to the accumulation of impurities in the tank, ensuring a continuous softening effect on the dirt.

[0014] Preferably, a connection and positioning mechanism is provided between the filter plate and the circulation box; The connecting positioning mechanism includes a rear plate symmetrically installed on the inner top surface of the filter plate, a front plate symmetrically installed on the outer top surface of the circulation box, the front plate and the rear plate overlapping the top of the circulation box, a connecting shaft seat installed on the outer side of the front plate, an adjusting screw connected to the end of the connecting shaft seat away from the front plate, a threaded sleeve sleeve on the outer ring of the adjusting screw, a snap-fit ​​plate fixedly sleeved on the outer ring of the threaded sleeve, snap-fit ​​seats symmetrically installed on the outer side of the circulation box, the snap-fit ​​seats engaging with the snap-fit ​​plates, a limit plate fixedly installed on the outer top of the front plate, and the snap-fit ​​plates slidingly connected with the limit plates.

[0015] With the above-mentioned structural design, the rear plate overlaps the front plate at the top of the circulation tank. The adjusting screw and threaded sleeve drive the snap-fit ​​plate to engage with the snap-fit ​​seat, which can firmly fix the filter plate in the circulation tank, prevent the filter plate from loosening during the circulation of cleaning liquid, and ensure the filtration effect. Rotating the adjusting screw controls the engagement or disengagement of the snap-fit ​​plate and the snap-fit ​​seat, facilitating quick disassembly and cleaning or replacement of the filter plate and improving cleaning convenience. The sliding fit between the limiting plate and the snap-fit ​​plate restricts the movement direction of the snap-fit ​​plate, preventing the snap-fit ​​plate from shifting when the adjusting screw is turned, and ensuring the reliability of the snap-fit ​​fixation.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the descaling device for the electrolytic cell with circulating filtration; 1. The internal descaling mechanism transmits the driving force evenly to the lifting scraper through the "X"-shaped connecting frame. With the trajectory restriction of the limiting frame, it ensures that the lifting scraper is stably attached to the inner wall of the tank. It can efficiently scrape the softened dirt in the height direction of the tank, avoiding missed scraping and jamming. The translation scraper driven by the second cylinder can specifically remove the deposited dirt at the bottom of the left and right ends of the tank, making up for the blind spots of cleaning the corners. Moreover, when it retracts, it does not affect the movement of the lifting scraper and the flow of cleaning liquid, thus improving the continuity of descaling. 2. The circulating filtration mechanism sends the cleaning solution containing dirt into the circulation tank through the output pump. After being filtered by the filter plate, it is stored and reused to avoid the accumulation of impurities and reduce the softening ability of the cleaning solution, thus ensuring continuous cleaning effect. The connection and positioning mechanism uses the overlap of the rear and front plates and the adjustment screw to drive the snap-fit ​​plate and snap-fit ​​seat to engage, ensuring that the filter plate works stably. At the same time, rotating the adjustment screw allows for quick disassembly and assembly of the filter plate, improving the convenience of cleaning and replacement. The limit plate also ensures the reliability of the snap-fit ​​fixation, indirectly enhancing the practicality and maintenance efficiency of the device. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: a descaling device for an electrolytic cell with circulating filtration, including a tank body 1, with support plates 2 symmetrically installed at the bottom of the tank body 1 for support, and an internal descaling mechanism installed inside the tank body 1 to scrape off dirt from the inner wall of the tank body 1. The internal descaling mechanism includes a lifting scraper 3 that slides against the inner ring of the tank body 1, a connecting frame 4 fixedly installed in the middle of the lifting scraper 3, the connecting frame 4 being arranged in an "X" shape, a first cylinder 5 fixedly installed at the bottom of the tank body 1, the shaft end of the first cylinder 5 being fixedly connected to the center of the connecting frame 4, and limit frames 6 symmetrically installed at the top of the left and right ends of the lifting scraper 3, the limit frames 6 being slidably connected to the tank body 1 through the tank body 1. The internal descaling mechanism also includes a translation scraper 7 embedded in the bottom of the inner side of the left and right ends of the tank body 1, and a second cylinder 8 fixedly installed in the middle of the left and right ends of the tank body 1, the shaft end of the second cylinder 8 being fixedly connected to the translation scraper 7. When the translation scraper 7 retracts, the inner wall surface is parallel to the inner wall surface of the left and right ends of the tank body 1. In the above-described structure, during cleaning operations, cleaning fluid is first injected into the tank 1 to soften the dirt on the inner wall. Then, the internal descaling mechanism is activated, and the first cylinder 5 outputs driving force. Its shaft end is fixedly connected to the center of the connecting frame 4, which has an "X" shaped structure. This allows the driving force to be evenly transmitted through the connecting frame 4 to the lifting scraper 3, which slides against the inner ring of the tank 1. This ensures that the lifting scraper 3 always maintains a stable fit against the inner wall of the tank 1. At the same time, the limiting frame 6 at the top of the left and right ends of the lifting scraper 3 is slidably connected to the tank 1, restricting the movement trajectory of the lifting scraper 3 and preventing it from tilting or getting stuck during the lifting process. Driven by the first cylinder 5, the lifting scraper 3 moves back and forth along the height direction of the tank 1 to scrape off the softened dirt on the side wall. After the lifting scraper 3 completes the descaling of the side wall, the second cylinder 8 in the middle of the left and right ends of the tank 1 is activated. Its shaft end drives the translation scraper 7, which is fitted and installed at the bottom of the inner side of the left and right ends of the tank 1, to perform a horizontal reciprocating motion, specifically scraping away the dirt deposited at the bottom. When the translation scraper 7 retracts, its inner wall surface is parallel to the inner wall surface of the left and right ends of the tank 1, without hindering the subsequent movement of the lifting scraper 3. Finally, through the cooperation of the lifting scraper 3 and the translation scraper 7, the inner wall of the tank 1 is descaled without dead corners.

[0021] A circulation tank 9 is fixedly installed on the front and rear sides of the tank 1. A filter plate 10 is installed inside the circulation tank 9. The circulation tank 9 is fixedly connected to the filter plate 10. A circulation filtration mechanism is installed at both ends and the bottom of the circulation tank 9 to circulate and filter the cleaning liquid. The circulation filtration mechanism includes an output pump 11 installed at equal intervals at the bottom of the circulation tank 9. The inlet end of the output pump 11 is connected to the bottom of the circulation tank 9. The outlet end of the output pump 11 is fixedly connected to an outlet pipe 12. The outlet pipe 12 is connected to the bottom of the tank 1. The circulation filtration mechanism also includes a circulation pump 13 fixedly installed on the left and right ends of the circulation tank 9. The inlet end of the circulation pump 13 is fixedly connected to an inlet pipe 14. The bottom end of the inlet pipe 14 is connected to the bottom of both ends of the circulation tank 9. The outlet end of the circulation pump 13 is fixedly connected to a connecting pipe 15. The outlet end of the connecting pipe 15 is connected to the top of both ends of the circulation tank 9. With the above structure design, the circulation pumps 13 on the left and right ends of the circulation tank 9 are activated, and the cleaning liquid containing scale is drawn from the bottom of the circulation tank 9 through the liquid inlet pipe 14. The liquid is then transported to the top of the circulation tank 9 through the connecting pipe 15 at the liquid outlet end of the circulation pump 13, so that the liquid forms a downward circulation flow in the circulation tank 9. During the process, the liquid flows through the filter plate 10 which is fixedly connected to the circulation tank 9, and the filter plate 10 filters the dirt particles in the liquid. The filtered cleaning solution collects at the bottom of the circulation tank 9. When cleaning is required again, the output pumps 11, which are installed at equal intervals at the bottom of the circulation tank 9, are started. The inlet end of the pump draws the filtered cleaning solution from the bottom of the circulation tank 9, and then sends the cleaning solution back to the tank 1 through the outlet pipe 12 at the outlet end. The solution is then used to soften and remove dirt from the inner wall of the tank 1, thereby realizing the circulation filtration and reuse of the cleaning solution.

[0022] Example 2: Based on Example 1, this utility model adopts the following... Figure 5-6 The technical solution shown further discloses that a connection positioning mechanism is connected between the filter plate 10 and the circulation box 9. The connection positioning mechanism includes a rear plate 16 symmetrically installed on the inner top surface of the filter plate 10, a front plate 17 symmetrically installed on the outer top surface of the circulation box 9, the front plate 17 and the rear plate 16 overlapping with the top of the circulation box 9, a connecting shaft seat 18 installed on the outer side of the front plate 17, an adjusting screw 19 connected to the end of the connecting shaft seat 18 away from the front plate 17, a threaded sleeve 20 threaded on the outer ring of the adjusting screw 19, a snap-fit ​​plate 21 fixedly sleeved on the outer ring of the threaded sleeve 20, a snap-fit ​​seat 22 symmetrically installed on the outer side of the circulation box 9, the snap-fit ​​seat 22 engaging with the snap-fit ​​plate 21, and a limiting plate 23 fixedly installed on the outer top of the front plate 17, the snap-fit ​​plate 21 slidingly connected with the limiting plate 23. In the above-described structure, when installing the filter plate 10, the rear mounting plate 16, which is symmetrically installed on the top inner side of the filter plate 10, is first overlapped with the front mounting plate 17, which is symmetrically installed on the top outer side of the circulation box 9, to complete the initial positioning. Then, through the connecting shaft seat 18 installed on the outer side of the front mounting plate 17, the adjusting screw 19 connected to the end away from the front mounting plate 17 is rotated. Since the outer ring of the adjusting screw 19 is threaded with a threaded sleeve 20, and the outer ring of the threaded sleeve 20 is fixedly fitted with a snap-fit ​​plate 21, the rotation will cause the snap-fit ​​plate 21 to slide along the limiting plate 23 fixedly installed on the top outer side of the front mounting plate 17 until the snap-fit ​​plate 21 engages with the snap-fit ​​seat 22 symmetrically installed on the outer side of the circulation box 9, thereby firmly fixing the filter plate 10 in the circulation box 9 and ensuring the stability of the filter plate 10 during the filtration process. When the filter plate 10 needs to be cleaned or replaced, rotate the adjusting screw 19 in the opposite direction to separate the snap plate 21 from the snap seat 22, and the filter plate 10 can be easily removed, realizing quick disassembly and assembly of the filter plate 10 and improving maintenance convenience.
