Description

Technical Field

[0001] This utility model relates to the field of galvanized steel strip processing technology, and in particular to a pretreatment cleaning device for galvanized steel strip. Background Technology

[0002] In the production process of galvanized steel strip, the cleanliness of the strip surface plays a decisive role in the galvanizing quality. During processing, transportation, and storage, the surface of the steel strip inevitably accumulates impurities such as oil, dust, iron filings, and oxide scale. If these impurities are not effectively removed before galvanizing, they will seriously affect the adhesion between the galvanized layer and the steel substrate, leading to defects such as peeling and blistering of the galvanized layer. This, in turn, reduces the corrosion resistance and service life of the galvanized steel strip, necessitating the use of cleaning equipment for treatment.

[0003] Cleaning operations can only maintain a certain cleaning effect by continuously injecting large amounts of fresh water and cleaning solution. However, the direct discharge of used cleaning solution and water not only leads to the unnecessary consumption of water resources and increases the water costs for enterprises, but also causes a large amount of wastewater containing pollutants such as oil, acid and alkali substances, and heavy metal ions to flow into the environment, causing serious pollution to the ecological environment such as soil and water bodies. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pretreatment cleaning device for galvanized steel strip. By starting a water pump and using a connecting pipe, water and cleaning fluid are drawn from the cleaning tank and sent to a filter tank. Upon reaching the filter tank, the water and cleaning fluid are filtered through a filter screen. The filtered water and cleaning fluid are then transported from the delivery pipe to the nozzle and then back into the cleaning tank. This allows for the reuse of the cleaning fluid, avoiding significant waste, reducing the amount of cleaning fluid needed for replenishment, and conserving water resources, thus meeting the requirements of energy conservation and emission reduction.

[0016] 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.

[0017] Reference Figure 1 - Figure 3This utility model provides an embodiment of a pretreatment cleaning device for galvanized steel strip, comprising: a connecting plate 1 serving as a supporting body; a filter box 2 fixedly connected to the front top of the connecting plate 1; connecting frames 3 fixedly connected to both sides of the inner wall of the filter box 2; sliding frames 4 slidably connected to the inner walls of the connecting frames 3; filter screens 5 slidably connected to the inner walls of the sliding frames 4; a connecting pipe 6 fixedly connected to the left end of the filter box 2; a water pump 7 fixedly connected to the right end of the filter box 2; a conveying pipe 8 fixedly connected to the right end of the water pump 7; a nozzle 9 fixedly connected to the rear end of the conveying pipe 8; a cleaning box 10 fixedly connected to the top of the connecting plate 1; a protective box 11 fixedly connected to the front end of the cleaning box 10; a first motor 12 fixedly connected to the front end of the protective box 11; and the drive end of the first motor 12 penetrating the protective box 11. A first rotating rod 13 is fixedly connected, and a second rotating rod 15 is connected to the first rotating rod 13 via a transmission assembly. Cleaning brushes 16 are fixedly connected to the outer walls of both the first rotating rod 13 and the second rotating rod 15. Positioning assemblies are provided on both sides of the top of the cleaning tank 10. The bottom end of the nozzle 9 is fixedly connected to the top of the cleaning tank 10. The outer walls of the first rotating rod 13 and the second rotating rod 15 are rotatably connected to the inner wall of the cleaning tank 10. Rollers 17 are fixedly connected to both sides of the top of the cleaning tank 10. Support rollers 18 are fixedly connected to both sides of the inner wall of the cleaning tank 10. A collecting roller 19 is provided at the right end of the cleaning tank 10. The outer wall of the connecting pipe 6 is fixedly connected to the inner wall of the cleaning tank 10. The transmission assembly includes gears 14 located on the outer wall of the first rotating rod 13 and on the outer wall of the second rotating rod 15, and the gears 14 are meshed together.

[0018] Specifically, during the cleaning process, a large amount of fresh water and cleaning solution is injected into the cleaning tank 10. At this time, the galvanized steel strip passes sequentially through the gaps between the roller 17, support roller 18, and cleaning brush 16, and then connects to the collecting roller 19. Once the installation is complete, the first motor 12 is started. When the first motor 12 operates, it drives the first rotating rod 13 to rotate synchronously. The rotation of the first rotating rod 13 causes the upper gear 14 to rotate, which in turn drives the lower gear 14 to rotate. The rotation of the lower gear 14 drives the second rotating rod 15 to rotate. With the rotation of the second rotating rod 15 and the first rotating rod 13, the cleaning brush 16 begins to operate, cleaning the surface of the galvanized steel strip. When it is necessary to circulate and filter the fresh water and cleaning solution, the water pump 7 is started. Water and cleaning fluid are extracted from the cleaning tank 10 through the connecting pipe 6 and transported to the filter tank 2. After entering the filter tank 2, the water and cleaning fluid flow through two filter screens 5. During this process, the filter screens 5 play a filtering role, intercepting impurities in the water. The filtered water and cleaning fluid are sent to the nozzle 9 through the conveying pipe 8, and then the nozzle 9 sends it back into the cleaning tank 10. Through this circulation system, the cleaning fluid can be reused, which greatly avoids the waste of a large amount of cleaning fluid, effectively reduces the amount of cleaning fluid to be replenished, and saves water resources, which fully meets the requirements of energy conservation and emission reduction. When the filter screen 5 needs to be replaced, the slide 4 can be pulled out from the inside of the connecting frame 3 to replace the filter screen 5. The collecting roller 19 can collect the cleaned galvanized steel strip.

[0019] Reference Figure 1 and Figure 4 The positioning component includes a fixed frame 20 fixedly connected to both sides of the top of the cleaning tank 10. A second motor 21 is fixedly connected to the top of each fixed frame 20. The drive end of each second motor 21 passes through the fixed frame 10 and is fixedly connected to a turntable 22. A rotating plate 23 is rotatably connected to both sides of the bottom of the turntable 22. A slide table 24 is slidably connected to both sides of the inner wall of the fixed frame 20. A positioning plate 25 is fixedly connected to the bottom of each slide table 24. The top of each slide table 24 is rotatably connected to the bottom of the rotating plate 23. The outer wall of the turntable 22 is rotatably connected to the inner wall of the fixed frame 20.

[0020] Specifically, when positioning the galvanized steel strip is required, the second motor 21 is started, and the drive end of the second motor 21 begins to rotate. This rotation immediately drives the turntable 22 connected to it to rotate synchronously. During the rotation of the turntable 22, the turntable 22 further drives the turntable 23 to rotate around its mounting axis. As the turntable 23 rotates, it pulls the slide 24 connected to it, causing the slide 24 to move. During the movement of the slide 24, it drives the positioning plate 25 fixed on it to move synchronously until the positioning plate 25 moves to the position above the roller 17. At this time, the positioning plate 25 can perform the positioning operation on the galvanized steel strip running on the roller 17. Through such a set of linked mechanical structures and operating mechanisms, it is possible to effectively prevent the steel plate from shaking or shifting during the pre-cleaning process, thereby greatly reducing the adjustment time caused by position deviation, reducing the scrap rate, and improving the overall production efficiency and product quality.

[0021] Working principle: During the cleaning process, a large amount of fresh water and cleaning solution is fed into the cleaning tank 10. The galvanized steel strip is then passed sequentially between roller 17, support roller 18, and cleaning brush 16, and connected to the top of the collecting roller 19. Upon installation, the first motor 12 is started, causing the first rotating rod 13 to rotate. The rotation of the first rotating rod 13 drives the upper gear 14, which in turn drives the lower gear 14. The rotation of the lower gear 14 then drives the second rotating rod 15. The rotation of both the second and first rotating rods 13 causes the cleaning brush 16 to clean the galvanized steel strip. When it is necessary to circulate and filter the fresh water and cleaning solution, the water pump 7 is started, using the connecting pipe 6 to draw water and cleaning solution from inside the cleaning tank 10 into the filter tank 2. Upon reaching the filter tank 2, the water and cleaning solution are filtered by two filter screens 5. The filtered water and cleaning solution are delivered from the conveying pipe 8 to the nozzle 9, and then from the nozzle 9 into the cleaning tank 10. This allows the cleaning solution to be reused, avoiding a large waste of cleaning solution and reducing the amount of cleaning solution to be replenished. It also saves water resources and meets the requirements of energy conservation and emission reduction. When the filter screen 5 needs to be replaced, the slide 4 can be pulled out from the inside of the connecting frame 3 and then the filter screen 5 can be replaced. When positioning is required, the second motor 21 is started and its drive end rotates, which drives the turntable 22 to rotate. When the turntable 22 rotates, it drives the rotating plate 23 to rotate. When the rotating plate 23 rotates, it pulls the slide 24 to move. When the slide 24 moves, it drives the positioning plate 25 to move on top of the roller 17 and then positions the galvanized steel strip. This prevents the steel plate from shaking or shifting during the pre-cleaning process and reduces the adjustment time and scrap rate caused by position deviation.
