[0010] Preferably, two spray pipes are fixedly connected to the movable pipe, and the two spray pipes are located above and below the steel strip, respectively.

[0011] Preferably, the spray pipe is uniformly and fixedly connected with rinsing nozzles, and the rinsing nozzles are arranged at an angle and facing the surface of the steel strip. At the same time, the rotating pipe drives the rinsing nozzles to uniformly rinse the surface of the steel strip.

[0012] Preferably, a second spring is fixedly connected between the filter plate and the tank, and the filter plate is inclined.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: Existing hot-dip galvanized steel strip production washing tanks mostly use a simple immersion and rinsing process, which fails to adequately remove impurities from the outer side of the strip. To solve this technical problem, this example discloses the following technical content. Please refer to [link / reference]. Figures 1-4 and Figures 6-8As shown; a washing tank for hot-dip galvanized steel strip production with cleaning function includes a tank body 1 for cleaning steel strip, a circulating water pump 2 fixedly installed at the bottom of the tank body 1, and a water supply pipe 3 connected to the output end of the circulating water pump 2, a motor 4 fixedly installed on the tank body 1, and a swing washing component for swinging the steel strip is installed on the inner side of the tank body 1, a guide roller 10 is rotatably installed on the inner side of the tank body 1, and a tensioning component for adjusting the tension of the steel strip is also provided on the inner side of the tank body 1, a movable pipe 15 is rotatably installed on the tank body 1, and spray pipes 16 are symmetrically installed on the movable pipe 15, and rinsing nozzles 17 are installed on the spray pipes 16. At the same time, the swing washing component drives the spray pipes 16 to swing through the transmission component during the swinging process, and a filter plate 19 with elastic lifting is provided on the inner side of the tank body 1.

[0019] The oscillating washing assembly includes a first guide rail 6 symmetrically fixedly installed on the inner wall of the tank 1, and a lifting adjustment seat 7 vertically slidably installed on the first guide rail 6. A drive disc 5 is fixedly installed at the output end of the motor 4. A connecting rod 9 is hinged between the edge of the drive disc 5 and the side wall of the lifting adjustment seat 7. During the rotation of the drive disc 5, the lifting adjustment seat 7 is driven to reciprocate up and down on the first guide rail 6 through the connecting rod 9. Two limit rollers 8 are rotatably installed parallel to each other on the lifting adjustment seat 7. The limit rollers 8 are located below the water surface in the tank 1, and the steel belt passes between the two limit rollers 8. At the same time, the lifting adjustment seat 7 drives the steel belt to oscillate through the limit rollers 8. The tensioning assembly includes two second guide rails 11 symmetrically fixedly installed on the inner wall of the tank 1. A lifting block 12 is slidably installed on the inner side of the second guide rail 11. A first spring 14 is fixedly connected between the lower ends of the lifting block 12 and the second guide rail 11. A tensioning roller 13 is rotatably connected between the two lifting blocks 12. The tensioning roller 13 is attached to and supported on the outside of the steel belt.

[0020] The produced hot-dip galvanized steel strip is conveyed by the limiting roller 8, guide roller 10, and tension roller 13, so that the hot-dip galvanized steel strip at the limiting roller 8 is immersed in the cleaning water. As the hot-dip galvanized steel strip is conveyed, the processed hot-dip galvanized steel strip can continuously enter the inner side of the tank 1. Then, the motor 4 is started, which drives the drive disc 5 to rotate. The drive disc 5 drives the lifting adjustment seat 7 to move up and down on the first guide rail 6 through the connecting rod 9. At this time, the two limiting rollers 8 on the lifting adjustment seat 7 can swing back and forth on the hot-dip galvanized steel strip passing between them, thereby accelerating the water flow to wash away impurities on the surface of the hot-dip galvanized steel strip. The swing washing method can effectively improve the cleaning effect. As the hot-dip galvanized steel strip swings, the tension roller 13 will drive the lifting block 12 to move up and down on the inner side of the second guide rail 11 and squeeze the first spring 14, so that the tension roller 13 can adjust the tension of the hot-dip galvanized steel strip, avoiding the pulling and loosening of the hot-dip galvanized steel strip during the swing, and ensuring the conveying stability of the hot-dip galvanized steel strip.

[0021] The movable tube 15 is rotatably connected to the inner side of the tank 1, and the upper end of the movable tube 15 is rotatably connected to the water supply pipe 3 in a sealed manner. The transmission component includes a winding wheel fixedly installed on the outer side of the upper end of the movable tube 15. At the same time, a traction cable 18 is wound around the outer side of the winding wheel. The other end of the traction cable 18 is fixedly connected to the upper end of the lifting adjustment seat 7. During the lifting adjustment of the lifting adjustment seat 7, the movable tube 15 is rotated and adjusted by pulling the traction cable 18. Two spray pipes 16 are fixedly connected to the movable tube 15, and the two spray pipes 16 are located above and below the steel strip respectively. A rinsing nozzle 17 is evenly fixedly connected to the spray pipe 16. The rinsing nozzle 17 is set at an angle and faces the surface of the steel strip. At the same time, during the rotation of the movable tube 15, the rinsing nozzle 17 is driven to rinse the surface of the steel strip evenly.

[0022] Start the circulating water pump 2 so that it can deliver the filtered cleaning water to the water supply pipe 3, and then enter the movable pipe 15 and the spray pipe 16 through the water supply pipe 3, so that the rinsing nozzle 17 can rinse the upper and lower surfaces of the hot-dip galvanized steel strip. As the lifting adjustment seat 7 is raised and lowered, it will pull the traction cable 18 fixedly connected to its top, so that the traction cable 18 can pull the movable pipe 15 to rotate. At this time, the movable pipe 15 drives the spray pipe 16 to rotate and swing back and forth, so that the rinsing nozzle 17 can rinse the residual impurities on the hot-dip galvanized steel strip to the side, further improving the cleaning effect on the surface of the hot-dip galvanized steel strip.

[0023] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. Existing hot-dip galvanized steel strip production water washing tanks are inconvenient to automatically clean the filter structure inside the tank during use, making them prone to clogging and affecting the recycling of washing water. To further solve this technical problem, this example discloses the following technical content: Figures 4-5 As shown; A second spring 20 is fixedly connected between the filter plate 19 and the tank 1, and the filter plate 19 is set in an inclined position. A first magnetic block 21 is fixedly installed at the lower end of the lifting adjustment seat 7, and a second magnetic block 22 is fixedly installed on the upper surface of the filter plate 19. The positions of the first magnetic block 21 and the second magnetic block 22 are arranged vertically and vertically, and the magnetic poles of the opposite surfaces of the first magnetic block 21 and the second magnetic block 22 are opposite.

[0024] During the cleaning process, the filter plate 19 can filter the washed-off impurities, ensuring that the circulating water pump 2 can draw clean water and avoid blockage in the subsequent pipeline. At the same time, as the lifting adjustment seat 7 is raised and lowered, the first magnetic block 21 at the lower end of the lifting adjustment seat 7 will move back and forth towards the second magnetic block 22, causing the filter plate 19 to shake under the action of the magnetic force in conjunction with the second spring 20. Since the filter plate 19 is set at an angle, the filtered impurities can be collected to the lower end of the filter plate 19 during the shaking process, thereby achieving the purpose of automatic cleaning and effectively preventing the filter plate 19 from becoming blocked.
