Description

Technical Field

[0001] This utility model belongs to the field of steel plate pickling technology, specifically, it relates to a steel coil pickling equipment. Background Technology

[0002] From the perspective of producing hot-dip galvanized steel sheets, the process of directly hot-dip galvanizing hot-rolled strip steel, similar to that of cold-rolled steel sheets, requires a clean and active surface before galvanizing. To obtain such a surface, the hot-rolled strip steel needs to be treated to remove surface iron oxide scale. The common practice is pickling. In the pickling process, some methods mainly remove the iron scale by dissolving the corresponding metal oxides through the chemical reaction between acid and iron. In others, such as when using sulfuric acid for steel pickling, the scale is also removed by the peeling effect of hydrogen bubbles generated by the chemical reaction between acid and steel. Therefore, a large amount of acid is inevitably consumed during the pickling process. Although the use of pickling corrosion inhibitors can reduce the metal consumption of steel, a considerable amount of metallic iron is still lost.

[0003] Chinese utility model patent CN220265854U discloses a steel plate pickling device. It is equipped with a pickling component, a cleaning component, and a storage component. The pickling component pickles the surface of the steel plate and uses heating to improve the pickling degree and speed. The cleaning component can clean the dirt and zinc powder on the surface of the steel plate to prevent the dirt from affecting the pickling effect. At the same time, the storage component can receive the liquid after pickling the steel plate and prevent the pickling liquid from falling directly to the ground.

[0004] Although the pickling equipment can pickle steel plates, when pickling steel coils, the steel plates are continuous and long plates. When pickling steel plates that have been unrolled from steel coils, the pickling effect is not good. Therefore, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a steel coil pickling equipment that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A steel coil pickling device includes a pickling tank, into which a pickling solution is added. Two upper and lower opposing limit rollers are rotatably connected to the outer wall of one side of the pickling tank. A conveying assembly is installed on the other side of the pickling tank. The conveying assembly transports the steel plate outward. One end of the steel coil passes through the two limit rollers and the two power rollers, causing the steel plate to fall into the pickling tank in a bent shape.

[0008] Furthermore, the upper end of the pickling tank is detachably connected to a mounting plate, and a pressing component is installed on the upper end of the mounting plate, which immerses the steel plate in the pickling solution.

[0009] Furthermore, a swaying assembly is installed on the top plate, which causes the steel plate to sway in the pickling solution.

[0010] Furthermore, the conveying assembly includes a power roller, meshing gears, and a first drive motor. The first drive motor is detachably connected to one side of the outer wall of the pickling tank. The rotating end of the first drive motor is detachably connected to one end of the power roller on one side. The other ends of the two power rollers are fixedly connected to a drive shaft that extends out of the pickling tank. The outer wall of the drive shaft is fixedly connected to a meshing gear, and the two meshing gears mesh with each other.

[0011] Furthermore, the pressing assembly includes an electric telescopic rod, a mounting bracket, a mounting bracket, and a pressing roller. The upper end of the pickling tank is detachably connected to a mounting top plate, and the electric telescopic rod is detachably connected above the mounting top plate. The telescopic end of the electric telescopic rod passes through the mounting top plate and is detachably connected to a mounting bracket with an opening facing downwards. The pressing roller is rotatably connected inside the mounting bracket.

[0012] Furthermore, the shaking assembly includes a piston cylinder, an inclined mounting plate, a fixed bracket, a second drive motor, an incomplete gear, a piston rod, a meshing tooth groove, a return spring, an extension rod, and a rubber head. The upper end of the mounting plate is detachably connected to the inclined mounting plate, and the outer wall of the inclined mounting plate is detachably connected to the piston cylinder. An opening is provided on the outer wall of the piston cylinder near its upper end. A piston rod is slidably connected inside the piston cylinder, and a return spring is provided between the piston rod and the piston cylinder. Multiple meshing tooth grooves are provided on the outer wall of the piston rod near its upper end. An extension rod that extends out of the piston cylinder is fixedly connected to the end of the piston rod, and a rubber head is detachably connected to the end of the extension rod. The outer wall of the inclined mounting plate is fixedly connected to the second drive motor, and the outer wall of the second drive motor is detachably connected to the second drive motor. An incomplete gear is detachably connected to the rotating end of the second drive motor. The incomplete gear meshes with the meshing tooth groove, and the rubber head is aligned with the steel plate inside the pickling tank that has not yet been pickled.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0014] 1. Pass one end of the steel coil through the two limit rollers and the two power rollers, so that the steel plate falls into the pickling tank in a bent shape. The pickled steel plate is then conveyed to one side by the power roller, thus completing the pickling of the steel coil.

[0015] 2. Through the set conveying components, the first drive motor rotates and drives the power roller on one side to rotate. Through the meshing of the meshing gears on both sides, the power rollers on both sides rotate in opposite directions to convey the steel plate to one side.

[0016] 3. Through the set pressing component, the electric telescopic rod extends, causing the mounting bracket and the electric telescopic rod to press downward, thereby pressing the steel plate into the pickling solution, and then pickling the steel plate in all directions.

[0017] 4. Through the set shaking component, the second drive motor rotates and drives the incomplete gear to rotate, so that the piston rod can extend and contact the steel plate through the meshing tooth groove. When the incomplete gear rotates to the toothless part, the return spring contracts and the piston rod returns to its original position, which can shake the steel plate. On the one hand, it makes the pickling effect better, and on the other hand, it makes the pickling solution inside flow.

Two upper and lower opposing limit rollers 101 are rotatably connected to one side of the outer wall of the pickling tank 100, and upper and lower opposing power rollers 200 are rotatably connected to the other side of the outer wall of the pickling tank 100. In this embodiment, one end of the steel coil is passed through the two limit rollers 101 and the two power rollers 200, causing the steel plate to fall into the pickling tank 100 in a bent shape. The pickled steel plate is conveyed to one side by the power rollers 200, thereby completing the pickling of the steel coil.

[0031] Referring to Figure 2, which is a schematic diagram of the conveying component structure in this embodiment, a first drive motor 202 is detachably connected to one side of the outer wall of the pickling tank 100. The rotating end of the first drive motor 202 is detachably connected to one end of a power roller 200 on one side. The other ends of the two power rollers 200 are fixedly connected to a drive shaft that extends out of the pickling tank 100. The outer wall of the drive shaft is fixedly connected to a meshing gear 201. The two meshing gears 201 mesh with each other. In this embodiment, the rotation of the first drive motor 202 drives the rotation of the power roller 200 on one side. The meshing of the two meshing gears 201 causes the two power rollers 200 to rotate in opposite directions, conveying the steel plate to one side.

[0032] It is worth noting that the aforementioned power roller 200, meshing gear 201, and first drive motor 202 are conveying components in this embodiment. The conveying components include, but are not limited to, the power roller 200, meshing gear 201, and first drive motor 202. Any component capable of conveying steel plates can be applied to this embodiment.

[0033] Referring to Figure 3, which is a schematic diagram of the pressing component structure in this embodiment, the upper end of the pickling tank 100 is detachably connected to a mounting top plate 102, and an electric telescopic rod 300 is detachably connected above the mounting top plate 102. The telescopic end of the electric telescopic rod 300 passes through the mounting top plate 102 and is detachably connected to a downward-facing mounting bracket 301. A pressing roller 302 is rotatably connected inside the mounting bracket 301. In this embodiment, the extension of the electric telescopic rod 300 causes the mounting bracket 301 and the electric telescopic rod 300 to press downward, thereby pressing the steel plate into the pickling solution and thus performing all-round pickling of the steel plate.

[0034] It is worth noting that the electric telescopic rod 300, mounting bracket 301, and pressing roller 302 mentioned above are the pressing components in this embodiment. The pressing components include, but are not limited to, the electric telescopic rod 300, mounting bracket 301, and pressing roller 302. Any component that can press the steel plate into the pickling solution can be used in this embodiment.

[0035] Referring to Figure 4, which is a schematic diagram of the swaying component structure in this embodiment, an inclined mounting plate 401 is detachably connected to the upper end of the mounting top plate 102. A piston cylinder 400 is detachably connected to the outer wall of the inclined mounting plate 401. An opening is provided on the outer wall of the piston cylinder 400 near its upper end. A piston rod 405 is slidably connected inside the piston cylinder 400. A return spring 407 is provided between the piston rod 405 and the piston cylinder 400.

An incomplete gear 404 is detachably connected to the rotating end of the second drive motor 403. The incomplete gear 404 meshes with the meshing groove 406. The rubber head 409 is aligned with the steel plate inside the pickling tank 100 that has not yet been pickled. In this embodiment, the rotation of the second drive motor 403 drives the incomplete gear 404 to rotate, thereby enabling the piston column 405 to extend through the meshing groove 406 to contact the steel plate with the extension rod 408 and the rubber head 409. When the incomplete gear 404 rotates to the toothless part, the return spring 407 contracts to reset the piston column 405, thereby shaking the steel plate. This improves the pickling effect and allows the pickling solution inside to flow.

[0036] It is worth noting that the piston cylinder 400, inclined mounting plate 401, fixed bracket 402, second drive motor 403, incomplete gear 404, piston column 405, meshing tooth groove 406, return spring 407, extension rod 408, and rubber head 409 mentioned above are the shaking components in this embodiment.
