Description

Technical Field

[0001] The utility model relates to the technical field of copper wire pickling, in particular to a copper wire pickling system. Background Art

[0002] Copper wire pickling refers to the use of acid to remove oxides, impurities and contaminants on the surface of the copper wire through chemical methods to achieve the purpose of cleaning and brightening. After pickling the copper wire, it is usually necessary to clean the residual pickling solution on the surface of the copper wire. After rinsing with clean water, the copper wire needs to be transferred to the next process station. Therefore, in order to avoid the copper wire being oxidized again during the transfer process, the copper wire needs to be soaked in soapy water. This not only makes the surface of the copper wire lubricated, which is convenient for subsequent processing, but also covers the surface of the copper wire with a protective layer to prevent the copper wire from being oxidized.

[0003] CN112111648B discloses a processing technology and immersion cleaning device for producing tinned copper wire using scrap copper wire. It mainly discloses an immersion cleaning device, which includes a box body 1, which is a square with an open top and a hollow interior. One end of the box body along its length is set as the upstream end, and the other end is set as the downstream end. A first partition and a second partition are fixedly provided in the box body along its length. The first partition and the second partition are parallel to each other, and the first partition is arranged along the width direction of the box body. An acid washing tank is formed between the first partition and the side wall of the upstream end of the box body, a cleaning liquid washing tank is formed between the first partition and the second partition, and a water washing tank is formed between the second partition and the side wall of the downstream end of the box body.

[0004] However, the copper wire of the above technical solution first passes through the pickling tank, then the cleaning liquid washing tank, and finally the water washing tank. This will not only make the pH value in the cleaning liquid washing tank lower and lower, but also the lubricating effect and protective layer produced by the copper wire in the cleaning liquid washing tank will be washed away in the water washing tank, which is not conducive to subsequent processing.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] Example 1

[0028] refer to Figures 1 to 3 A copper wire pickling system includes a hoisting unit 1, a pickling unit 2, a cleaning unit 3, and an alkaline lubrication unit 4. The hoisting unit 1 is used to lift a copper wire coil and drive the copper wire coil to be immersed in the pickling unit 2, the cleaning unit 3, and the alkaline lubrication unit 4 in sequence.

[0029] The pickling unit 2 is used to pickle the copper wire to remove oxides and impurities on the surface of the copper wire;

[0030] The cleaning unit 3 is used to clean the pickling material on the copper wire;

[0031] The alkaline lubrication unit 4 is used to lubricate the surface of the copper wire and cover the surface of the copper wire with a protective layer.

[0032] Under this design, the operator hangs the copper wire roll on the hoisting unit 1, drives the copper wire roll to the top of the pickling unit 2 through the hoisting unit 1, and drives the copper wire roll downward to be immersed in the pickling unit 2, and the pickling liquid in the pickling unit 2 is used to remove oxides, impurities and pollutants on the surface of the copper wire to achieve the purpose of cleaning and brightening; then the hoisting unit 1 drives the copper wire roll to the top of the cleaning unit 3, and drives the copper wire roll downward to be immersed in the cleaning unit 3, and the cleaning liquid in the cleaning unit 3 is used to clean the residual pickling liquid on the copper wire roll, and the pH in the cleaning unit 3 will also be reduced. The subsequent operator can drain the liquid in the cleaning unit 3 and recycle the pickling liquid through an external device; after cleaning is completed, the hoisting unit 1 drives the copper wire roll to the top of the alkaline lubrication unit 4, and drives the copper wire roll downward to be immersed in the alkaline lubrication unit 4, and the alkaline lubricating liquid is used to further remove the residual pickling liquid on the copper wire roll, while lubricating the surface of the copper wire and covering the surface of the copper wire with a protective layer, which is convenient for subsequent transfer and processing.

[0033] Preferably, the cleaning unit 3 is a cleaning tank, in which a cleaning module 31 is provided. The cleaning module 31 comprises a tube located in the cleaning tank, with multiple outlets 311 provided on the tube, and the tube is connected to an external input device, which may be an external gas delivery device.

[0034] Preferably, the tube body is a vortex structure, one end of the tube body is closed, and the outlet 311 is located on the side of the tube body. Further, the tube body is a vortex structure, one end of the tube body is closed, and the outlet 311 is located on the side of the tube body. When the tube body adopts a vortex structure, the outlet 311 can cover a wider range of positions.

[0035] In this embodiment, the cleaning unit 3 is provided with a first drain pipe 32, and the cleaning tank is filled with clean water. The operator can drain the cleaning liquid in the cleaning tank through the first drain pipe 32 and recover the pickling liquid.

[0036] Preferably, the pickling unit 2 is a pickling tank, and an overflow tank 21 is provided on the side wall of the pickling tank. An overflow hole 22 matching the overflow tank 21 is provided on the pickling tank. The overflow tank 21 is connected to an external circulation device through a pipe. A liquid inlet pipe 23 and a liquid outlet pipe 24 are provided on the pickling tank, and the liquid inlet pipe 23 and the liquid outlet pipe 24 are both located at the lower part of the pickling tank.

[0037] Specifically, because the purpose of pickling is to remove oxides, impurities and contaminants on the surface of the copper wire, it is inevitable that there will be floating objects on the surface of the pickling liquid after pickling. By adding an overflow trough 21 and an overflow hole 22, as well as a liquid inlet pipe 23 located at the lower part of the pickling tank, liquid inlet and outlet can be achieved at the bottom of the pickling tank. By controlling the liquid inlet and outlet amounts, the pickling liquid can overflow from the overflow hole 22, overflowing the floating objects on the surface and allowing the pickling liquid in the pickling tank to flow.

[0038] In this embodiment, the alkaline lubrication unit 4 is an alkaline lubrication tank, in which soap water is loaded. Soap water is selected because soap water is more economical and has both alkaline and lubricating effects.

[0039] In this embodiment, a guide module 5 is also included, which includes a fixing frame 51 and a guide plate 52 connected to the fixing frame 51. The guide plate 52 is arranged at an angle, and the lowest point of the guide plate 52 is located above the alkaline lubrication unit 4. The guide plate 52 is used to receive the liquid dripping from the copper wire coil and guide it back to the alkaline lubrication unit 4.

[0040] In actual use, after the copper wire roll is soaked in the alkaline lubrication unit 4 and taken out, excess soapy water will drip from the copper wire roll. If the copper wire roll is kept above the alkaline lubrication unit 4, it will affect the subsequent copper wire rolls. Therefore, a guide module 5 is added to guide the dripping soapy water back to the alkaline lubrication unit 4 through the guide plate 52.

[0041] Furthermore, the alkaline lubrication unit 4 is provided with a second drain pipe 41. The second drain pipe 41 is used to drain the soapy water in the alkaline lubrication unit 4, so as to facilitate the replacement of the soapy water.

[0042] In this embodiment, the hoisting unit 1 includes a moving module 11 and a lifting module 12 connected to the moving module 11 . A support frame 13 for fixing the copper wire coil is provided on the power output end of the lifting module 12 .

[0043] Specifically, the operator fixes the copper wire coil on the support frame 13 and drives the copper wire coil to move above the pickling unit 2, cleaning unit 3 or alkaline lubrication unit 4 through the moving module 11. The lifting module 12 drives the copper wire coil downward to the corresponding immersion position for immersion. Among them, the moving function and the lifting function can be realized by a crane, and the moving module 11 and the lifting module 12 are the corresponding functional components of the crane.

[0044] Although the embodiments of the present application have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and intent of the present application, and that the scope of the present application is defined by the claims and their equivalents.
