Description

Technical Field

[0001] This utility model belongs to the field of pickling tank technology, specifically a pickling tank for steel wire processing. Background Technology

[0002] Pickling tanks are containers used to hold aqueous solutions and remove thin films from metal surfaces during the pickling process. They have good alkali resistance, acid resistance, high temperature resistance, and corrosion resistance. Pickling tanks are widely used in the pickling industry of metallurgy, electroplating, and other industries. During the processing of steel wire, an oxide scale will form on the surface when it is formed at high temperature. When the steel wire is drawn, the residual oxide scale can easily scratch the mold. Therefore, in order to remove the surface oxide layer and impurities, a pickling tank for steel wire processing is needed.

[0003] A Chinese patent with authorization announcement number CN213266708U discloses a pickling tank for steel wire processing, which includes a pickling tank body and a fixed sliding plate. A lifting groove is provided in the middle of the upper part of the pickling tank body. Two evenly symmetrically distributed control cylinders are fixedly connected to the left and right sides of the upper end face of the lifting groove. An electric control slider is fixedly connected to the upper end face of the control cylinders. A heating layer is provided between the inner side wall and the outer side wall of the pickling tank body. This utility model belongs to the field of pickling tank technology.

[0004] However, the above solution still has some problems. When multiple sets of steel wires enter the pickling tank for pickling, the steel wires will accumulate, which can easily lead to dead corners between the steel wires, thus reducing the pickling quality of the steel wires. Therefore, in order to solve the above problems, a pickling tank for steel wire processing is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes an acid pickling tank for steel wire processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a pickling tank for steel wire processing, comprising: a carbon steel frame, a reinforcing frame fixedly connected to the outer surface of the carbon steel frame, a fiberglass anti-corrosion layer fixedly connected to the inner wall of the carbon steel frame, a PP sheet provided on the inner wall of the fiberglass anti-corrosion layer, a grid plate fixedly connected to the inner wall of the PP sheet, a grid plate opening at the bottom of the grid plate, a drive motor installed at the bottom of the carbon steel frame, an adjusting plate fixedly connected to the output end of the drive motor, the adjusting plate being rotatably connected inside the PP sheet, a connecting rod fixedly connected to the upper surface of the PP sheet, a rotating ring rotatably connected to the connecting rod, a connecting plate provided on the outer side of the rotating ring, support rods fixedly connected to both sides of the connecting plate, and a limit ring fixedly connected inside the PP sheet, the limit ring restricting the movement range of the support rod, thereby improving the stability of the component during reciprocating movement.

[0007] Preferably, the support rod is slidably connected inside the limiting ring, and a slider is fixedly connected to the upper surface of the support rod. The slider is slidably connected inside the grid plate, and the steel wire is located above the grid plate, thereby separating the push plate and the steel wire.

[0008] Preferably, a push plate is fixedly connected to the upper surface of the slider, and hollow plates are fixedly connected to both sides of the push plate. The push plate and hollow plates are located below the grid plate. The push plate and hollow plates cooperate to generate a high shear flow when moving, which can destroy the stagnant layer on the surface of the steel wire, so that the steel wire comes into more comprehensive contact with the acid solution and improves the pickling quality of the pickling tank on the steel wire.

[0009] Preferably, the PP sheet has an internal sandwich layer, and a conical air outlet is provided at the top of the sandwich layer. A spiral plate is fixedly connected to the inner wall of the conical air outlet. The spiral plate disrupts the laminar boundary layer and reduces turbulence. At the same time, the spiral plate guides the airflow to flow along the wall, avoiding the generation of separation vortices in the diffuser section, thereby reducing the pressure loss when the gas is blown out.

[0010] Preferably, an air supply pipe is threaded to one side of the PP sheet, one end of which extends into the interior of the interlayer. An air pump is threaded to one end of the air supply pipe. The air pump is started by an external controller to compress the air and transmit it to the interior of the interlayer through the air supply pipe. The air is then ejected outward through a conical air outlet, thereby forming an air curtain above the PP sheet.

[0011] Preferably, the pickling tank is connected to an external controller, which is used to control the start and stop of the drive motor and the air pump. By controlling the drive motor and the air pump through the external controller, the convenience of using the pickling tank is improved.

[0012] The advantages of this invention are as follows: through the cooperation of the drive motor, adjusting plate, connecting rod, rotating ring, connecting plate and support rod, the push plate and hollow plate are driven to move back and forth, thereby shaking the pickling water and making its concentration distribution more uniform. The holes in the hollow plate compress the air and generate an upward jet, which, together with the push plate, forms a spiral three-dimensional flow field, which increases the acid renewal frequency on the steel wire surface, destroys the stagnant layer on the steel wire surface, and makes the steel wire more fully contacted with the acid, thereby improving the pickling quality of the steel wire in the pickling tank.

[0013] This invention uses an air pump, air supply pipe, conical air outlet, and spiral plate to form an air curtain on the top of the PP sheet. When the pickled steel wire is removed, the steel wire automatically forms a dynamic seal as it passes through the air curtain, thus scraping the acid adhering to the surface of the steel wire into the interior of the PP sheet and preventing the acid from flowing out with the steel wire. This avoids acid splashing when the steel wire is removed, thereby improving the safety of the pickling tank during use. Attached Figure Description

[0017] 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 scope of protection of the present utility model.

[0018] Please see Figure 1-5As shown, a pickling tank for steel wire processing includes: a carbon steel frame 1, a reinforcing frame 2 fixedly connected to the outer surface of the carbon steel frame 1, a fiberglass anti-corrosion layer 3 fixedly connected to the inner wall of the carbon steel frame 1, a PP sheet 4 provided on the inner wall of the fiberglass anti-corrosion layer 3, a grid plate 5 fixedly connected to the inner wall of the PP sheet 4, a grid plate 5 having an opening at the bottom of the grid plate 5, a drive motor 6 installed at the bottom of the carbon steel frame 1, an adjusting plate 7 fixedly connected to the output end of the drive motor 6, the adjusting plate 7 being rotatably connected inside the PP sheet 4, and a [missing information - likely a component or material] fixedly connected to the upper surface of the PP sheet 4. A connecting rod 8 is rotatably connected to a rotating ring 9. A connecting plate 10 is provided on the outer side of the rotating ring 9. Support rods 11 are fixedly connected to both sides of the connecting plate 10. A limit ring 12 is fixedly connected inside the PP sheet 4. The support rod 11 is slidably connected inside the limit ring 12. A slider 13 is fixedly connected to the upper surface of the support rod 11. The slider 13 is slidably connected inside the grid plate 5. A push plate 14 is fixedly connected to the upper surface of the slider 13. Hollow plates 15 are fixedly connected to both sides of the push plate 14. The push plate 14 and the hollow plates 15 are located below the grid plate 5. During the processing of steel wire, an oxide scale forms on the surface during high-temperature forming. When the steel wire is drawn, the residual oxide scale can easily scratch the mold. Therefore, to remove the surface oxide layer and impurities, a pickling tank for steel wire processing is needed. In practical use, the carbon steel frame 1 has anti-deformation capabilities, improving the load-bearing strength of the pickling tank. The fiberglass anti-corrosion layer 3 has high hydrochloric acid resistance, forming a corrosion barrier to prevent acid from penetrating into the carbon steel frame 1. The PP sheet 4 serves as the lining of the pickling tank; its chemical inertness prevents chemical reactions with the pickling water, thus avoiding damage to the pickling tank during steel wire pickling. Furthermore, the reinforcement frame 2 reinforces the outside of the carbon steel frame 1, extending the service life of the pickling tank. During the pickling process, the drive motor 6 is started by an external controller. The drive motor 6 rotates the adjusting plate 7, which in turn moves the connecting rod 8 around the output shaft, pushing the connecting plate through the rotating ring 9. 10, causing the connecting plate 10 and the support rods 11 on both sides to reciprocate, thereby driving the push plate 14 and hollow plate 15 to move synchronously with the support rods 11 via the slider 13. When the push plate 14 and hollow plate 15 move, they push the pickling water, allowing the pickling water in the PP sheet 4 to be in a sloshing state, thus making the pickling water concentration distribution inside the PP sheet 4 more uniform. When the hollow plate 15 moves, its holes compress the air, generating an upward jet, which, together with the push plate 14, forms a spiral three-dimensional flow field, increasing the acid refresh frequency on the steel wire surface. Furthermore, the high shear flow generated when the push plate 14 and hollow plate 15 move can destroy the stagnant layer on the steel wire surface, thereby pushing the pickling water at the bottom and driving the pickling water in the pickling tank to flow. This not only destroys the stagnant layer on the steel wire surface, making the steel wire more fully contacted with the acid, but also makes the pickling water concentration distribution more uniform, thereby improving the pickling quality of the steel wire in the pickling tank.

[0019] Please see Figure 1-5 As shown, a sandwich layer 16 is provided inside the PP sheet 4, and a conical air outlet 17 is provided at the top of the sandwich layer 16. A spiral plate 18 is fixedly connected to the inner wall of the conical air outlet 17. An air supply pipe 19 is threadedly connected to one side of the PP sheet 4. One end of the air supply pipe 19 extends into the interior of the sandwich layer 16, and an air pump 20 is threadedly connected to one end of the air supply pipe 19. A controller is connected to the outside of the slot. The external controller is used to control the start and stop of the drive motor 6 and the air pump 20. The air pump 20 is started by an external controller to compress the air, which is then transmitted to the interior of the interlayer 16 through the air supply pipe 19. The air is then ejected outward through the conical air outlet 17. Because the conical air outlet 17 is conical, the air is accelerated when it passes through the conical air outlet 17, which increases the dynamic pressure at the outlet of the conical air outlet 17. The spiral plate 18 disrupts the laminar boundary layer and reduces the turbulence. At the same time, the spiral plate 18 guides the airflow to flow along the wall, avoiding the generation of separation vortices in the diffuser section, thereby reducing the pressure loss when the gas is blown out. When multiple conical air outlets 17 eject gas at the same time, an air curtain can be formed above the PP sheet 4. When the pickled steel wire is taken out, the steel wire automatically forms a dynamic seal when it passes through the air curtain, thereby scraping the acid attached to the surface of the steel wire into the interior of the PP sheet 4, preventing the acid from being ejected with the steel wire, thus avoiding acid splashing when the steel wire is removed, and thus improving the safety of the pickling tank during use.

[0020] Working principle: During the pickling process, the external controller starts the drive motor 6, which rotates the adjusting plate 7. This, in turn, moves the connecting rod 8 around the output shaft. The rotating ring 9 pushes the connecting plate 10, causing the connecting plate 10 and the support rods 11 on both sides to reciprocate. This, in turn, drives the push plate 14 and hollow plate 15 to move synchronously with the support rods 11 via the slider 13. The movement of the push plate 14 and hollow plate 15 pushes the pickling water, breaking up the stagnant layer on the steel wire surface. This increases the acid refresh frequency on the steel wire surface, resulting in more comprehensive contact between the steel wire and the acid, thus improving pickling efficiency. The pickling quality of steel wire is ensured by an external controller starting the air pump 20 to compress air, which is then transmitted to the interior of the interlayer 16 through the air supply pipe 19. The air is then sprayed outward through the conical air outlet 17. The spiral plate 18 guides the airflow to flow along the wall, preventing the generation of separation vortices in the diffusion section. When the pickled steel wire is removed, it automatically forms a dynamic seal as it passes through the air curtain, thereby scraping the acid adhering to the surface of the steel wire into the interior of the PP sheet 4, preventing the acid from flowing out with the steel wire. This avoids acid splashing when the steel wire is removed, thus improving the safety of the pickling tank during use.
