Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel strip pickling lines, and particularly relates to a post-pickling blowing device for stainless steel strips. Background Art

[0002] The pickling of stainless steel strips is an important surface treatment technology. It uses an acidic solution to clean and treat the surface of stainless steel strips to remove scale, welding slag, metal oxides, and dirt on the surface, thereby improving the surface finish and corrosion resistance of stainless steel strips. Through pickling treatment, the surface of stainless steel strips can reach a smooth and bright state, while removing the oxide layer and other pollutants, making the surface smoother. This not only improves the appearance quality of stainless steel strips but also enhances their corrosion resistance and aesthetics. In addition, pickling treatment can also provide a good foundation for subsequent processes such as electroplating, coloring, polishing, and passivation, ensuring the stable performance of stainless steel strips during processing and use.

[0003] After retrieval, the surface blowing device of the strip pickling line with the authorized announcement number of CN 218710879 U in the prior art is convenient for filtering the slag generated during the pickling process, so it is not easy to cause acid solution pollution and improves the continuous pickling effect. It includes an acid tank; conveying ports are provided at both the left and right ends of the acid tank; a fixing plate; a filter plate is fixedly connected in the acid tank, the fixing plate is fixedly connected in the acid tank, and two first electric cylinders are installed on the fixing plate. The output ends of the two first electric cylinders penetrate through the fixing plate and are fixedly connected with a lifting plate; a cleaning mechanism is installed on the fixing plate and is used for cleaning the slag on the surface of the strip; a circulating mechanism: the circulating mechanism is installed on the acid tank and is used for circulating the acid solution; a conveying mechanism: the conveying mechanism is installed on the acid tank and is used for conveying the strip. The surface blowing device of this strip pickling line does not have a limiting mechanism and cannot effectively solve the lateral deviation that occurs during the strip conveying process.

[0004] After retrieval, a purging device for removing residual acid in an acid pickling process with the authorized announcement number of CN 216095297 U in the prior art includes an operation box. A guide rail is fixedly connected to the center of the inner top surface of the operation box. A truss is slidably connected to the inner surface of the guide rail. A clamping manipulator is fixedly connected to the bottom surface of the truss. Guide rods are fixedly connected between the inner top surface and the inner bottom surface on both sides of the truss in the operation box. In the present utility model, the servo motor can drive the acid removal roller and the gas nozzle to remove the residual acid on the surface of the sheet. After the residual acid on the surface of the sheet is cleaned by the gas nozzle and the acid removal roller, only a small amount of clean water is needed for cleaning, which saves water resources and improves the efficiency of removing residual acid. The movement of the acid removal hoop driven by the hydraulic expansion rod can scrape the residual acid remaining in the bristles on the outer edge of the acid removal roller, avoiding too much residual acid remaining in the bristles and making it difficult to carry out the acid removal work, ensuring the cleaning efficiency of the acid removal roller and also facilitating the recovery of residual acid. This device uses a manipulator to clamp the strip steel, and the clamping effect on strip steels with different thicknesses is different, and there is a risk of falling off during the clamping process.

[0029] A pickling and purging device for stainless steel strip steel, and its working process is as follows:

[0030] During operation, the stainless steel strip steel is fed between the feeding roller 101 and the pressing roller 102 of the strip steel conveying mechanism 12. The feeding roller 101 is driven to rotate by the motor II 104, and the pressing roller 102 is driven to rotate by the motor I 103 to feed the stainless steel strip steel into the feeding port 21. The upper pressing roller 102, through the spring 106 between the limiting block 108 and the upper positioning plate 105, plays the role of pressing the stainless steel strip steel while conveying it, and also plays the role of position limitation through the sliding connection between the T-shaped positioning plate 112 and the limiting sliding groove 113. Thus, it can convey strip steels of different thicknesses while pressing the strip steel, increasing the friction force between the upper and lower rollers and the strip steel, ensuring that the stainless steel strip steel can enter the treatment area smoothly and efficiently, and improving the working efficiency.

[0031] The stainless steel strip steel enters the internal treatment area of the box body 11. The conveying roller 15 in the box body 11 plays the functions of positioning the stainless steel strip steel and auxiliary transmission. The electric push rods I 201 on both sides of the limiting mechanism 13 push out the limiting push plates 203, making the limiting push plates 203 fit with the stainless steel strip steel.

By the limiting mechanism 13, the position of the strip steel in the box body is ensured, effectively preventing the lateral offset of the strip steel during the conveying process, ensuring the accurate position of the strip steel in the box body, and ensuring the smoothness of the device during operation; the spray head water pipe 19 starts to spray clean water on the stainless steel strip steel.

[0032] The stainless steel strip steel continues to move forward to the extrusion and cleaning mechanism 14. The motor III 307 drives the brush roller 306 to rotate. The lead screw motor 301 controls the up and down movement of the positioning slider 304. The positioning slider 304 is connected to the main shaft 310, driving the main shaft 310 and other mechanisms on the main shaft to lift and lower together.

The limiting rings 311 on the main shaft 310 and the sliding connection shaft 318 control the contraction and expansion of the arc-shaped support plate 309 through the connecting rod 312. The rubber brush roller sleeve 308 is sleeved on the arc-shaped support plate 309, and the contraction and expansion of the arc-shaped support plate 309 drive the contraction and expansion of the rubber brush roller sleeve 308; by controlling the up and down movement of the main shaft 310 by the lead screw motor 301 and the contraction and expansion of the arc-shaped support plate 309 by the electric push rod II 317, the stainless steel strip steel can be tightly attached to the upper rubber brush roller sleeve 308 and the lower brush roller 306. The motor III 307 controls the rotation of the brush roller 306 to drive the forward displacement of the stainless steel strip steel. When the stainless steel strip steel passes through the extrusion and cleaning mechanism 14, the upper and lower surfaces are effectively cleaned.

[0033] The stainless steel strip reaches the area provided with the purging air pipes 20 after passing through the extrusion and cleaning mechanism 14. The purging air pipes 20 are distributed vertically and horizontally, which can purge the water and impurities on the surface of the stainless steel strip. Before the stainless steel strip reaches the discharge port 22 after purging, it is further cleaned by the second group of extrusion and cleaning mechanisms 14, and then sent out of the device by the strip conveying mechanism 12 at the discharge port 22 to complete the work.
