Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell maintenance technology, and in particular to a device for maintaining the integrity of an aluminum electrolytic cell. Background Technology

[0002] An electrolytic cell is a device used to realize the electrolysis process. It promotes the decomposition of electrolytes by reduction and oxidation reactions at the anode and cathode. An electrolytic cell mainly consists of electrodes, electrolyte, and cell body. Common electrode materials include graphite and metals. Electrolytes are mostly aqueous solutions, molten salts, or solid electrolytes. Electrolytic cells can be divided into aqueous solution electrolytic cells, molten salt electrolytic cells, and solid electrolyte electrolytic cells. In the chemical industry, electrolysis of brine can produce caustic soda, chlorine, and hydrogen. In the metallurgical industry, metallic aluminum can be produced by electrolyzing molten alumina. In addition, it also plays an important role in battery manufacturing, wastewater treatment, and other fields.

[0003] In existing technologies, electrolytic cells generate high temperatures during operation. Long-term operation in a high-temperature environment may lead to problems such as damage and leakage. Inspection requires manual contact with the electrolytic cell using testing equipment, which exposes maintenance personnel to high temperatures and strong magnetic fields. Electrolyte splashes can threaten the safety of workers. After welding repairs, the welded area also needs to be ground to ensure the required precision. Both processes consume a lot of time, affecting the efficiency of electrolytic cell damage maintenance. Therefore, to solve the above problems, this utility model proposes an aluminum electrolytic cell damage maintenance device. Utility Model Content

A servo motor drives the maintenance mechanism to achieve integrated welding and grinding operations, preventing the consumption of a large amount of time between two operations. While maintaining the repair accuracy of the electrolytic cell, it also improves the efficiency of the device in maintaining the damaged electrolytic cell.

A servo motor 4 is fixedly installed on the upper part of the top plate 1. A transmission gear roller 5 is fixedly connected to the output shaft of the servo motor 4 via a coupling. A transmission gear belt 6 is engaged with the outer edge of the transmission gear roller 5. A transmission gear roller 7 is engaged with the bottom end of the transmission gear belt 6. The transmission gear roller 7 is fixedly sleeved with the threaded rod 3. A slider 8 is movably sleeved on the threaded rod 3 and is movably connected to the groove 2. Two electric push rods 9 are fixedly installed at the bottom of the slider 8 and are symmetrically distributed front and back. A welding machine 10 and a grinding machine 11 are fixedly installed at the telescopic ends of the two electric push rods 9, respectively. A connecting plate 12 is fixedly installed at the bottom of the top plate 1, located directly behind the electric push rods 9. An infrared scanner 13 is fixedly installed at the bottom of the connecting plate 12. The electrolytic cell operates normally through the infrared scanner 13 at the bottom of the top plate 1. When the temperature is high, the infrared scanner can perform detection without contacting the tank by receiving the infrared energy radiated by the object itself. This avoids the risk of maintenance personnel being exposed to high temperature, strong magnetic field and electrolyte splash. It is also conducive to quickly locating the damaged position that needs maintenance in emergency scenarios. The servo motor 4 drives the transmission toothed roller 5 to rotate. The transmission toothed roller 5 drives the transmission toothed roller 7 to rotate through the transmission toothed belt 6. The transmission toothed roller 7 drives the threaded rod 3 to make the slider 8 slide in the slide groove 2. This moves the bottom mechanism of the slider 8 to above the damaged position. The electric push rod 9 at the rear drives the welding machine 10 to descend, thereby welding and filling the damaged area. After the weld has completely cooled, the electric push rod 9 at the front drives the grinding machine 11 to descend and grind the welded area. This realizes the integrated operation of welding and grinding, preventing a lot of time to be spent between two operations.

The inner cavity of the right slide groove 17... A sliding rod 24 is fixedly connected, and two support rods 14 are movably connected to threaded rod 23 and sliding rod 24 respectively. The device is moved by casters 16, which facilitates transportation and enhances the flexibility of the device. The base 15 surrounds the aluminum electrolytic cell. The hydraulic rod 18 is opened so that its telescopic end drives the clamping plate 19 to extend. The clamping plate 19 contacts the outer surface of the electrolytic cell to fix the electrolytic cell and prevent it from shaking. This improves the stability of the electrolytic cell during maintenance operations and also helps to fix electrolytic cells of different sizes, improving the applicability of the device. The servo motor 20 drives the helical gear 21 to rotate. The engagement of helical gear 21 and helical gear 22 causes the threaded rod 23 to rotate. The threaded rod 23, in conjunction with the sliding rod 24, moves the support rod 14. The support rod 14 moves the top plate 1 back and forth, which helps the damage maintenance mechanism to quickly adjust its position and ensures that the device has good working efficiency.

The hydraulic rod 18 is activated, causing its telescopic end to extend the clamping plate 19. The clamping plate 19 contacts the outer surface of the electrolytic cell, fixing it in place. The servo motor 20 drives the helical gear 21 to rotate. The engagement of helical gear 21 and helical gear 22 causes the threaded rod 23 to rotate. The threaded rod 23, in conjunction with the sliding rod 24, moves the support rod 14. The support rod 14 moves the top plate 1 back and forth, activating the infrared scanner 13 at the bottom of the top plate 1. The main function of the infrared scanner 13 is to detect the surface of objects. The thermal radiation is used to generate temperature images. Thermal imaging is used to identify the inner cavity of the electrolytic cell and determine the damaged location that needs maintenance.
