[0020] like Figures 1 to 3 As shown, a surface cleaning device for cold-rolled strip steel includes a main body 1. A squeezing table 2 and multiple washing tanks 6 are sequentially installed on the main body 1 according to the material conveying direction of the strip steel 11. Baffles are provided on both sides of the main body 1, with two baffles located on either side of the washing tanks 6. The height of the baffles is higher than the height of the washing tanks 6. The multiple washing tanks 6 are arranged in a stepped manner along the material conveying direction of the strip steel 11. The height of the washing tanks 6 located further away from the squeezing table 2 is higher than the height of the washing tanks 6 located closer to the squeezing table 2. Adjacent washing tanks 6 are connected by a water guide plate 8. The water guide plate 8 is provided with a concave water guide groove. The water guide plate 8 is located above the lower of the two washing tanks 6 and connected to the higher of the two washing tanks 6. Guide rollers 7 are provided on both sides of each washing tank 6.
[0021] The strip steel 11 is cleaned through multiple tiered washing tanks 6. The flowing water in the washing tanks 6 has a certain impact force and fluidity, which can continuously wash the surface of the strip steel 11, remove the attached acid and other stains in time, prevent the stains from adhering to the surface of the strip steel 11, and reduce residues. In addition, the flowing water can penetrate into the gaps and holes on the surface of the strip steel 11 to wash away the stains in the gaps, improve the cleaning effect of the strip steel 11, and make the cold-rolled strip steel 11 thoroughly cleaned, thereby removing the acid from the surface of the cold-rolled strip steel 11 for subsequent storage.
[0022] There are more than 3 washing pools.
[0023] The squeezing table 2 is equipped with squeezing rollers 3 arranged vertically. The squeezing rollers 3 are used to initially squeeze the strip steel 11. After passing through the squeezing rollers 3, the strip steel 11 enters the washing tank 6 for further cleaning, which improves the cleaning efficiency and quality.
[0024] An inclined guide groove 4 is provided on the upper end face of the squeezing table 2, and the squeezing roller 3 is located above the inclined guide groove 4. A water receiving cavity 5 is provided inside the squeezing table 2. The bottom surface of the inclined guide groove 4 is provided with multiple water passage holes communicating with the water receiving cavity 5. The solution on the strip steel 11 is squeezed off by the squeezing roller 3 and falls onto the squeezing table 2, flows into the inclined guide groove 4, and flows into the water receiving cavity 5 through the water passage holes, reducing the amount of solution entering the washing tank 6 for contamination and improving the cleaning efficiency of the strip steel 11.
[0025] The bottom surface of the water receiving cavity 5 is inclined, and a drain pipe is provided at the lowest point of the bottom surface of the water receiving cavity 5 on the side wall of the squeezing table 2 to facilitate the discharge of the solution in the water receiving cavity 5.
[0026] The drain pipe is inclined, and the height of one end of the drain pipe that connects to the water receiving cavity 5 is higher than the other end of the drain pipe, so as to facilitate the discharge of the solution in the water receiving cavity 5.
[0027] The washing tank 6 is equipped with two roller brushes arranged vertically, which are symmetrically distributed with respect to the strip steel 11. A drain pipe is also provided at the bottom of the washing tank 6. The roller brushes facilitate the cleaning of residual acid and other substances on the surface of the strip steel 11.
[0028] like Figures 2 to 3 As shown, each washing tank 6 is equipped with a spray structure located above the strip steel 11 to ensure thorough removal of dirt from the surface of the strip steel 11. The spray structure includes an air blowing pipe 9 installed on the outlet side of the washing tank 6. The air blowing pipe 9 is V-shaped and has multiple air blowing ports 10 on its wall for blowing air onto the surface of the strip steel 11. The air blowing ports 10 are located diagonally below the air blowing pipe 9. One side of the air blowing pipe 9 is equipped with an air injection port connected to a gas source. The air blowing pipe 9 is used to blow air onto the upper surface of the strip steel 11. The gas source injects gas into the air blowing pipe 9 through the air injection port. The gas in the air blowing pipe 9 blows away the moisture on the strip steel 11 through the air blowing ports 10, reducing the residual moisture on the strip steel 11.
[0029] The shortest straight-line distance between the middle part of the air blowing pipe 9 and the strip 11 is less than the shortest straight-line distance between the end of the air blowing pipe 9 and the strip 11. The middle part of the air blowing pipe 9 quickly agitates the moisture in the middle of the strip 11. The air blown out by the air blowing ports 10 on both sides of the air blowing pipe 9 blows the moisture on both sides of the strip 11, quickly blowing away the moisture on the strip 11, effectively preventing moisture from remaining on the sides of the strip 11, and significantly improving the air blowing quality of the pickled strip 11.
