Description

Technical Field

[0001] This utility model relates to the field of copper processing equipment, and in particular to a simple acid addition device for cleaning copper strips. Background Technology

[0002] In the production of copper strip, acid baths are typically used to treat and clean the copper strip to remove surface oxides and impurities. Therefore, in actual production, sulfuric acid needs to be added to the acid bath periodically.

[0003] In existing operations, concentrated sulfuric acid is usually added to the acid tank manually. However, since there are no special containers to hold the concentrated sulfuric acid, and multiple cleaning production lines are operating simultaneously, a large amount of sulfuric acid needs to be added. Using manual acid replenishment outside the production line poses a significant safety hazard. Therefore, this solution proposes a simple external acid addition device for copper strip cleaning lines to address the above problems. Utility Model Content

[0033] 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 protection scope of the present utility model.

[0034] Example 1: This utility model provides the following... Figure 1 - Figure 4 The device shown is a simple acid addition device for cleaning copper strip wires, including an acid addition tank 1. The bottom of the acid addition tank 1 is provided with an acid discharge structure for discharging concentrated sulfuric acid. Multiple sets of supporting steel pipes 2 are fixedly connected to the bottom end of the acid addition tank 1, and multiple hooks 7 are symmetrically fixedly connected to the top of the acid addition tank 1.

[0035] It should be noted that the hook 7 facilitates the hoisting and movement of the acid tank 1, and the supporting steel pipe 2 ensures that the acid tank 1 is supported off the ground, thus protecting the bottom of the acid tank 1.

[0036] Specifically, the acid-removing structure includes:

[0037] Discharge pipe 3 is installed at the bottom of acid addition tank 1 and is connected to the bottom of acid addition tank 1.

[0038] The guide plate 13 is fixedly connected to the bottom inner wall of the acid addition tank 1.

[0039] Furthermore, the guide plate 13 is inclined at 3°-8°, and the lower end of the guide plate 13 is located at the junction of the discharge pipe 3 and the acid tank 1.

[0040] It should be noted that in the actual setup, a corrosion-resistant control valve is installed at the discharge point of the discharge pipe 3. The discharge is quantitatively controlled by the on / off control of the valve. In order to ensure that the concentrated sulfuric acid in the acid tank 1 is stably guided to the discharge pipe 3, the guide plate 13 is set so that the concentrated sulfuric acid is guided by gravity to the connection between the discharge pipe 3 and the acid tank 1.

[0041] Example 2: This utility model provides a liquid level measuring mechanism, which is applied to a simple acid addition device for copper strip cleaning wires in Example 1. The liquid level measuring mechanism is installed on the side wall of the acid addition tank 1 and is used to monitor the discharge of concentrated sulfuric acid.

[0042] Specifically, the liquid level measuring mechanism includes:

[0043] The connecting parts, with multiple sets of connecting parts respectively penetrating and installed at the top and bottom of the side wall of the acid tank 1;

[0044] The magnetic level gauge 14 has its measuring end connected to one end of multiple connecting parts away from the acid tank 1.

[0045] It should be noted that the magnetic float level gauge 14 consists of a housing, a measuring tube, a float, and a flip indicator. The housing is made of corrosion-resistant material and can withstand the corrosion of sulfuric acid. The measuring tube is built into the housing, through which the liquid flows. The float, containing a magnet, is also built into the measuring tube. The flip indicator is installed on the outside of the housing and is typically a flip plate with both red and white colors. When liquid enters the measuring tube, the float rises or falls due to buoyancy, and its floating height corresponds to the liquid level. The magnet inside the float moves with the float's movement. When the float rises or falls, it generates a change in the magnetic field within the measuring tube. The external flip indicator is affected by the float's magnetic field, and the internal flipping mechanism changes the color of the flip plate (alternating between white and red) according to the float's position. When the float rises, the flip plate flips to red, indicating a rise in liquid level; when the float falls, the flip plate flips to white, indicating a fall in liquid level.

[0046] Furthermore, the connecting part includes:

[0047] Measuring flange 4, one end of which is connected through to the tank wall of acid tank 1;

[0048] Ball valve 5, one end of which is connected through to the end of measuring flange 4 away from acid tank 1;

[0049] An external flange 6 is provided, with one end of the external flange 6 being connected to the end of the ball valve 5 away from the measuring flange 4, and the other end of the external flange 6 being used to connect to the magnetic level gauge 14. The magnetic level gauge 14 and the acid tank 1 are connected through the measuring flange 4, the ball valve 5 and the external flange 6.

[0050] In Example 3, this utility model provides a feeding mechanism, which is applied to a simple acid-adding device for cleaning copper strip wires in Example 1. The feeding mechanism is located on the top of the acid-adding tank 1 and is used to add concentrated sulfuric acid into the acid-adding tank 1.

[0051] Specifically, the feeding mechanism includes:

[0052] Welded flange 8 is connected to the top of acid tank 1.

[0053] End cap 10, which is disposed at the top of the butt-welding flange 8;

[0054] Sealing gasket 9 is disposed between the top end of the butt-welding flange 8 and the bottom end of the end cover 10.

[0055] It should be noted that the welding flange 8 is connected to the top of the acid tank 1. After opening the end cover 10, concentrated sulfuric acid can be added into the acid tank 1 along the welding flange 8 to replenish the concentrated sulfuric acid in the acid tank 1, which is convenient for delivery to various cleaning production lines. The sealing gasket 9 ensures the sealing stability after the welding flange 8 and the end cover 10 are connected, thereby ensuring the stable storage of concentrated sulfuric acid in the acid tank 1.

[0056] Furthermore, multiple sets of fastening bolts 12 are interlocked around the top edge of the butt-welded flange 8 and the end cap 10, and multiple handles 11 are fixedly connected to the top of the end cap 10.

[0057] It should be noted that the end cover 10 and the butt-welding flange 8 are detachably fixed after being connected by the fastening bolts 12, and the end cover 10 can be picked up and put down by the handle 11.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
