Technical Field
[0001] This utility model belongs to the field of alloy wire processing technology, and in particular relates to an acid pickling device for hard-state tin-plated copper-clad steel wire. Background Technology
[0002] A pickling tank is a container used to hold aqueous solutions and remove the thin film from the metal surface during the pickling process. It possesses excellent resistance to alkalis, acids, high temperatures, and corrosion. Pickling is necessary during the production of hard-plated tin-coated copper-clad steel wire to remove rust, scale, and other impurities from its surface, thereby improving the quality of the hard-plated tin-coated copper-clad steel wire.
[0003] When existing pickling equipment is in use, the pickling solution inside is in a stagnant or poorly fluid state, making it difficult to dissipate the heat generated during the pickling process. This results in excessively high local temperatures and rapid evaporation of the pickling solution, leading to uneven pickling solution concentration and affecting the pickling effect on alloy wires.
[0004] Therefore, it is necessary to improve the pickling equipment in the existing technology. Utility Model Content
[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a pickling device for hard-plated tin-coated copper-clad steel wire, which improves the pickling effect on alloy wire.

[0025] like Figure 1-3 As shown, a pickling device for hard-plated tin-coated copper-clad steel wire includes a pickling tank 1 with an open top. A cylindrical rinsing mechanism 2 is raised and lowered directly above the pickling tank 1 and rotates around its own axis. The rinsing mechanism 2 includes a converging section and a dispersing section. The converging section is equipped with converging blades 201 for driving the pickling liquid to flow from the outside to the inside of the rinsing mechanism 2, and the dispersing section is equipped with dispersing blades 202 for driving the pickling liquid to flow from the inside to the outside of the rinsing mechanism 2.
[0026] The above-mentioned pickling equipment is suitable for pickling alloy wires such as tin-plated copper-clad steel wire. During use, the pickling tank 1 contains pickling solution, and the rinsing mechanism 2 is immersed in the pickling solution. The pickling tank 1 is equipped with guide wheels to guide the alloy wire's forward direction. Under the action of the guide wheels, the alloy wire passes coaxially through the rinsing mechanism 2. During this process, the rinsing mechanism 2 rotates, and the converging vanes 201 introduce the pickling solution from outside the rinsing mechanism 2 into its interior, causing the pickling solution to flush the alloy wire. The dispersing vanes 202 guide the pickling solution inside the rinsing mechanism 2 to the outside, thereby achieving convection of the pickling solution inside and outside the rinsing mechanism 2. This process allows the heat generated during pickling to diffuse and dissipate with the flow of the pickling solution, thus maintaining a uniform temperature and reducing the likelihood of excessive evaporation in localized areas due to overheating. It also improves the uniformity of the pickling solution concentration. Furthermore, the convection of the pickling solution mixes it, further enhancing the uniformity of concentration and improving the pickling effect on the alloy wire. During the convection process, the pickling solution washes over the alloy wire, removing impurities adhering to it and ensuring full contact between the pickling solution and the alloy wire, further improving the pickling effect.
[0027] Further improvements include, for example Figure 3 As shown, the rinsing mechanism 2 has multiple converging sections and multiple dispersing sections arranged along its own axis, with the converging sections and dispersing sections staggered. After the multiple converging sections and multiple dispersing sections are staggered, the rinsing mechanism can form multiple small internal and external circulation convections during rotation, thereby improving the convection effect of the pickling solution and ultimately improving the pickling effect of the pickling equipment on the alloy wire.
[0028] Further improvements include, for example Figure 3 As shown, the rinsing mechanism 2 includes multiple coaxially arranged support rings 203, with a flow-gathering section and a flow-diffusing section respectively disposed between two adjacent support rings 203. The support rings 203 are fixedly connected to the flow-gathering blades 201 and the flow-diffusing blades 202, providing support and reinforcement to the flow-gathering blades 201 and the flow-diffusing blades 202 from both ends, thereby improving the stability and reliability of the equipment operation.
[0029] Further improvements include, for example Figure 4 As shown, the converging vanes 201 are evenly distributed around the axis of the support ring 203, and the minimum distance between the converging vanes 201 and the axis of the support ring 203 gradually decreases along the rotation direction of the support ring 203. During the rotation of the converging vanes 201, the pickling liquid moves relative to the converging vanes 201, causing the pickling liquid to flow along the distribution direction of the converging vanes 201. This pushes the pickling liquid along the gaps between the converging vanes 201 towards the axis of the support ring 203, thereby pushing the pickling liquid outside the rinsing mechanism 2 inward.
[0030] Further improvements include, for example Figure 5 As shown, the diffuser blades 202 are evenly distributed around the axis of the support ring 203, and the minimum distance between the diffuser blades 202 and the axis of the support ring 203 gradually increases along the rotation direction of the support ring 203. During the rotation of the diffuser blades 202, the pickling solution moves relative to the diffuser blades 202, causing the pickling solution to flow along the distribution direction of the diffuser blades 202. This pushes the pickling solution along the gaps between the diffuser blades 202 in a direction away from the axis of the support ring 203, thereby pushing the pickling solution inside the rinsing mechanism 2 to the outside. By simultaneously moving the pickling solution from the outside to the inside and from the inside to the outside, convection of the pickling solution inside and outside the rinsing mechanism 2 can be achieved, improving the uniformity of the pickling solution concentration and temperature. Furthermore, the radial flow of the pickling solution along the rinsing mechanism 2 can also achieve the rinsing of the alloy wire.
[0031] Further improvements include, for example Figure 1 and 2As shown, the pickling tank 1 is equipped with a lifting mechanism, wherein two support rings 203 are connected to the lifting mechanism through bearings 204. The lifting mechanism is equipped with a drive unit for driving the support rings 203 to rotate. The outer ring of the bearing 204 is coaxially and detachably connected to a bearing seat. The bearing seat is vertically equipped with a guide rod 104. The pickling tank 1 is fixedly connected to a guide sleeve 105 through a gantry frame 101. The guide rod 104 and the guide sleeve 105 are slidably engaged. The top end of the guide rod 104 is fixedly connected to a lifting plate 103. The pickling tank 1 is equipped with a power component 102 for driving the lifting plate 103 to rise and fall. The drive unit is set on the lifting plate 103.
[0032] Specifically, the gantry frame 101 is used to fix the guide sleeve 105, which guides and supports the guide rod 104. The power component 102 is a hydraulic cylinder, which pushes the guide rod 104 to rise and fall, thereby realizing the lifting and lowering of the rinsing mechanism 2. By controlling the height of the rinsing mechanism 2, the rinsing mechanism 2 can be raised above the pickling liquid page, which facilitates the threading of alloy wire in the rinsing mechanism 2 and also facilitates the maintenance of the rinsing mechanism 2. The drive unit includes a servo motor 301 fixedly connected to the lifting plate 103. The servo motor 301 is driven by a drive wheel, which is driven by a conveyor belt 302 and one of the support rings 203. Thus, the servo motor 301 drives the rinsing mechanism 2 to rotate, thereby realizing the convection of the pickling liquid.
[0033] Further improvements include, for example Figure 2 As shown, the bearing housing includes two semi-circular unit seats 106, both ends of which are connected to two guide rods 104 by bolts. Each unit seat 106 has a through hole at its end, and the bottom end of each guide rod 104 has a threaded section that passes through the ends of both unit seats 106 and is secured with nuts. This facilitates the disassembly and reassembly of the guide rods 104 and the two unit seats 106, thereby improving the ease of assembly and disassembly of the flushing mechanism 2 and enhancing equipment maintenance.
[0034] Further improvements include, for example Figure 3 As shown, both the diffuser blade 202 and the converging blade 201 are thin-plate structures. The thin-plate structure of the diffuser blade 202 and the converging blade 201 allows for faster heat exchange. When the top part of the rinsing mechanism 2 is exposed above the pickling solution surface, heat exchange between the pickling solution, air, and between the diffuser blade 202 and the converging blade 201 can be achieved, thereby dissipating the heat from the pickling solution into the air, cooling the pickling solution, and improving the pickling effect of the pickling equipment on the alloy wire.
