Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0047] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or service tool that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or service tool.

[0048] Copper foil can be widely used in many fields due to its excellent conductivity, good flexibility and moderate potential. For example, copper foil can be used to prepare circuit boards, composite materials and current collectors for lithium-ion batteries.

[0049] Copper foil can be made by electrolytic copper foil. The production process of electrolytic copper foil includes: copper dissolving process, raw foil process, post-processing process and slitting process. Each process is briefly described below. Copper dissolving process: copper raw material and sulfuric acid solution are added to the copper dissolving tank, and the copper raw material is dissolved in the sulfuric acid solution to form a copper sulfate solution. Raw foil process: copper sulfate solution is injected into the electrolytic cell. Under the action of direct current, the copper sulfate solution is electrodeposited on the surface of the cathode roller to form raw foil. After the continuous rotation of the cathode roller, the raw foil can be peeled off. Post-processing process: the raw foil is pickled in the pickling tank, and then an anti-oxidation layer is coated on the surface of the raw foil to form copper foil. The copper foil is rolled up to form a copper foil roll. Slitting process: the copper foil is cut into the required size.

[0050] Among them, the copper dissolving process is the first step in the production of electrolytic copper foil. The copper dissolving efficiency and copper dissolving quality play an important role in the subsequent quality of copper foil. The copper dissolving tank is provided with an aeration pipe, which is arranged at the bottom of the copper dissolving tank. The gas enters the copper dissolving tank from the aeration pipe. Through the circulation of the gas, the copper raw material can be dissolved more evenly in sulfuric acid, and the dissolution efficiency of the copper raw material in sulfuric acid can be improved.

[0051] In the related art, an aeration pipe is arranged at the bottom of a copper dissolving tank, which is usually a cylindrical structure. The height of the copper dissolving tank is greater than its diameter. Therefore, the bottom area of ​​the copper dissolving tank is small. The aeration pipe is arranged at the bottom, so that the amount of gas supplied by the aeration pipe is small, and the gas has insufficient power when it is close to the upper part of the copper dissolving tank. Therefore, the uniformity of dissolution of the copper raw material in sulfuric acid is poor and the dissolution efficiency of the copper raw material is low.

[0052] Based on this, the present application provides a copper dissolving tank device, which can improve the uniformity and dissolution efficiency of copper raw materials in sulfuric acid solution.

[0053] Figure 1 A schematic diagram of the structure of a copper dissolving tank device provided in an embodiment of the present application; Figure 2 This is a schematic diagram of the structure of the tank body in the copper dissolving tank device provided in an embodiment of the present application.

[0054] See also Figure 1 and Figure 2 As shown, the copper dissolving tank device 100 provided in the embodiment of the present application includes a tank body 110 and a plurality of aeration components 120. The tank body 110 includes a bottom wall 111 and a side wall 112. Each aeration component 120 includes an aeration pipe 121. The plurality of aeration pipes 121 are evenly spaced on the side wall 112. The aeration pipe 121 is connected to the interior of the tank body 110 to inject gas into the interior of the tank body 110.

[0055] Specifically, the tank body 110 is a cylindrical structure, and the tank body 110 includes a bottom wall 111 and a side wall 112 . The tank body 110 has a circumferential direction C and a height direction H. The side wall 112 extends from the bottom wall 111 along the height direction H. The bottom wall 111 and the side wall 112 enclose a receiving cavity 113 in the tank body 110 .

[0056] The tank body 110 is provided with a feeding port 114 , which is disposed at the upper end of the tank body 110 . A cover body 115 is provided on the feeding port 114 . The feeding port 114 is used for adding copper raw materials.

[0057] The feeding port 114 can be set at the upper end of the tank body 110, and the projection of the feeding port 114 on the bottom wall 111 can be circular or rectangular. The copper raw material can be added into the tank body 110 through the feeding port 114. After the copper raw material is added, a cover body 115 can be installed on the feeding port 114 to prevent foreign matter from falling into the accommodating cavity 113.

[0058] The tank body 110 is also provided with a liquid inlet pipe (not shown in the figure), which can be provided at the upper end of the tank body 110 or on the side wall 112 of the tank body 110, and the sulfuric acid solution can be injected into the containing cavity 113 from the liquid inlet pipe. The copper raw material is dissolved in the sulfuric acid solution to form a copper sulfate solution. In order to improve the uniformity of the dissolution of the copper raw material in the sulfuric acid solution and the dissolution efficiency of the copper raw material, an aeration assembly 120 can be provided on the tank body 110.

[0059] Please continue to see Figure 2 As shown, the side wall 112 of the tank body 110 has a plurality of first mounting holes 1121 evenly spaced apart. The first mounting holes 1121 are through holes that can connect the accommodating cavity 113 of the tank body 110 and the outside of the tank body 110 .

[0060] The aeration assembly 120 includes an aeration tube 121 , and the aeration tube 121 may be inserted into the first mounting hole 1121 . It should be noted that the aeration tube 121 and the first mounting hole 1121 may be sealed and connected.

[0061] Gas is injected from the aeration pipe 121 , and the gas may be air or oxygen. The gas is injected into the containing chamber 113 , and the power of the gas improves the uniformity of the dissolution of the copper raw material in the sulfuric acid solution and the dissolution efficiency of the copper raw material.

[0062] In the embodiment of the present application, the aeration tubes 121 are evenly spaced on the side wall 112 of the tank body 110, and the expanded surface area of ​​the side wall 112 is larger than the area of ​​the bottom wall 111. Therefore, more aeration tubes 121 can be arranged on the side wall 112 relative to the bottom wall 111, so that more gas can be injected into the accommodating cavity 113, thereby improving the uniformity of dissolution of the copper raw material in sulfuric acid and the dissolution efficiency of the copper raw material.

[0063] The tank body 110 is provided with aeration pipes 121 along the height direction H. Therefore, the power of the gas injected at the upper end and the lower end along the height direction H of the tank body 110 is relatively high. Compared with the related art in which the gas power above the tank body is insufficient, the uniformity of the dissolution of the copper raw material in sulfuric acid and the dissolution efficiency of the copper raw material can be further improved.

[0064] In addition, the aeration tube 121 is arranged on the side wall of the tank body 110 to prevent copper residue in the copper sulfate solution from falling onto the aeration tube 121 and blocking the aeration tube 121. When the aeration tube 121 is blocked, the amount of gas entering the accommodating chamber 113 will be reduced, thereby reducing the uniformity of dissolution of the copper raw material in sulfuric acid and the dissolution efficiency of the copper raw material.

[0065] The copper dissolving tank device 100 provided in the embodiment of the present application is provided with a tank body 110 and a plurality of aeration components 120, the tank body 110 includes a bottom wall 111 and a side wall 112, each aeration component 120 includes an aeration tube 121, and the plurality of aeration tubes 121 are evenly spaced on the side wall 112, and the aeration tube 121 is connected to the inside of the tank body 110 to inject gas into the inside of the tank body 110. The surface area of ​​the side wall 112 is larger than the area of ​​the bottom wall 111, so that more aeration tubes 121 can be provided on the side wall 112, so that more gas can be injected into the accommodating cavity 113, thereby improving the uniformity and dissolution efficiency of the copper raw material in the sulfuric acid solution. The tank body 110 is provided with aeration tubes 121 along the height direction H, and the power of the gas injected at the upper end and the lower end of the height direction H of the tank body 110 is relatively high, which can further improve the uniformity and dissolution efficiency of the copper raw material in the sulfuric acid solution.

[0066] In a possible implementation, adjacent aeration tubes 121 along a height direction H of the tank body 110 are aligned, and adjacent aeration tubes 121 along a circumferential direction C of the tank body 110 are staggered.

[0067] For ease of description, the side wall 112 of the tank body 110 is unfolded.

[0068] Figure 3 A schematic diagram of the structure of the unfolded side wall of the tank body in the copper dissolving tank device provided in an embodiment of the present application.

[0069] See also Figure 3 As shown, the side wall 112 of the tank body 110 is a rectangle after being unfolded, and two adjacent sides of the rectangle are in the circumferential direction C and the height direction H respectively.

[0070] When the first mounting holes 1121 are provided on the side wall 112, the first mounting holes 1121 adjacent in the height direction H are aligned and provided, and the first mounting holes 1121 adjacent in the circumferential direction C of the tank body 110 are staggered. Thus, the aeration pipes 121 provided on the first mounting holes 1121 are aligned in the height direction of the tank body 110 and staggered in the circumferential direction C of the tank body 110. In this way, the number of aeration pipes 121 can be increased as much as possible while maintaining the strength of the tank body 110.

[0071] Figure 4 A schematic structural diagram of the end surface of an aeration tube in a copper dissolving tank device provided in an embodiment of the present application.

[0072] Please continue to see Figure 1 and Figure 4 As shown, the aeration pipe 121 includes a first pipe section 1211 and a second pipe section 1212 connected to the first pipe section 1211. The first pipe section 1211 is located outside the tank body 110, and the second pipe section 1212 extends into the tank body 110. The end surface of the second pipe section 1212 has multiple aeration ports 1212a.

[0073] The aeration pipe 121 is inserted into the first mounting hole 1121, and the first pipe section 1211 is located outside the accommodating chamber 113. The first pipe section 1211 is used to communicate with the gas supply device, and the second pipe section 1212 extends deep into the accommodating chamber 113. A mesh screen is provided on the end surface of the second pipe section 1212, and the mesh screen has a plurality of aeration ports 1212a, thereby making the gas pressure and flow rate entering the accommodating chamber 113 more stable, which is more conducive to the dissolution of the copper raw material in the sulfuric acid solution.

[0074] Please continue to see Figure 1 As shown, the aeration assembly 120 further includes a plurality of protective covers 122 , and each second pipe segment 1212 is covered with a protective cover 122 .

[0075] The aeration pipe 121 can be made of stainless steel, which is resistant to acid corrosion. A protective cover 122 can be provided on the second pipe section 1212, and the protective cover 122 can be made of polytetrafluoroethylene (PTFE) or other corrosion-resistant materials, thereby further reducing the corrosion of the second pipe section 1212 of the aeration pipe 121 by the sulfuric acid solution. It can be understood that the end of the protective cover 122 away from the side wall 112 is an open structure.

[0076] In the embodiment of the present application, the length of the second tube segment 1212 is less than or equal to 1 / 3 of the radius of the bottom wall 111 .

[0077] Please continue to see Figure 1 As shown, the length of the second pipe section 1212 of the aeration pipe 121 is shown as the pipe section length L, and the radius of the bottom wall 111 is shown as the bottom wall radius R.

[0078] When the pipe section length L of the second pipe section 1212 is too large, the second pipe section 1212 will affect the circulation of the sulfuric acid solution in the accommodating cavity 113, and the second pipe section 1212 is more easily corroded by the sulfuric acid solution.

[0079] Therefore, in the embodiment of the present application, the length L of the pipe section is less than or equal to 1 / 3 of the radius of the bottom wall 111 .

[0080] Please continue to see Figure 1 As shown, the aeration assembly 120 further includes a plurality of mounting supports 123 , and the first pipe section 1211 of the aeration pipe 121 is connected to the side wall 112 of the tank body 110 via the mounting supports 123 .

[0081] Specifically, the mounting bracket 123 can be mounted on the side wall 112 of the tank body 110 by means of fasteners, and the mounting bracket 123 has a second mounting hole (not shown in the figure).

[0082] When installing the aeration pipe 121, first align the second mounting hole with the first mounting hole 1121, install the mounting bracket 123 on the side wall 112 of the tank body 110 through fasteners, pass the aeration pipe 121 through the second mounting hole and the first mounting hole 1121 in sequence to insert it into the accommodating cavity 113, and then fix the aeration pipe 121 and the mounting bracket 123 through fasteners.

[0083] By providing the mounting support 123 , the installation of the aeration pipe 121 can be facilitated and the force on the side wall 112 at the first mounting hole 1121 can be reduced.

[0084] Please continue to see Figure 1 As shown, the copper dissolving tank device 100 further includes an air intake manifold 130 , and the plurality of aeration pipes 121 are all connected to the air intake manifold 130 ; the copper dissolving tank device 100 further includes an air pump 140 , and the air pump 140 is disposed on the air intake manifold 130 .

[0085] The air intake manifold 130 is provided with an air pump 140, and the gas generated by the air pump 140 may have pressure, and each aeration pipe 121 is connected to the air intake manifold 130. The pressurized gas generated by the air pump 140 may enter the plurality of aeration pipes 121 through the air intake manifold 130, and enter the accommodating chamber 113 through the plurality of aeration pipes 121.

[0086] By providing an air intake main pipe 130 and making multiple aeration pipes 121 connected to the air intake main pipe 130, the layout of the pipelines in the copper dissolving tank device 100 can be simplified, and the pressure of the gas in each aeration pipe 121 can be made close, thereby avoiding the problem of uneven flow rate of gas in different areas of the accommodating chamber 113, thereby causing inconsistent concentration of copper sulfate solution in different areas.

[0087] Please continue to see Figure 1 As shown, the copper dissolving tank device 100 further includes a protection tank 150 , which is disposed on the outside of the tank body 110 and the plurality of aeration assemblies 120 .

[0088] The radius of the protection tank 150 is greater than the sum of the radius of the tank body 110 and the length of the second pipe section 1212. The protection tank 150 is covered on the tank body 110 and multiple aeration assemblies 120, which can protect the tank body 110 and the aeration assemblies 120 and make the appearance of the copper dissolving tank device 100 smoother and more beautiful.

[0089] The upper end of the protective tank 150 also has an opening, the diameter of the opening is the same as the diameter of the feeding port 114, and the projection of the opening on the bottom wall 111 roughly coincides with the projection of the feeding port 114 on the bottom wall 111, thereby preventing the protective tank 150 from blocking the feeding port 114.

[0090] Please continue to see Figure 1 As shown, the copper dissolving tank device 100 also includes a discharge pipe 160 and a valve 170. The discharge pipe 160 is arranged near the lower end of the tank body 110 along the height direction H and is connected to the tank body 110. The valve 170 is arranged on the discharge pipe 160. The discharge pipe 160 is used to discharge the copper sulfate solution inside the tank body 110.

[0091] The discharge pipe 160 is disposed near the lower end of the tank body 110, so that the copper sulfate solution can be discharged through the discharge pipe 160 by its own weight. Specifically, when the copper sulfate solution needs to be discharged from the tank body 110, the valve 170 is opened; when the copper sulfate solution does not need to be discharged from the tank body 110, the valve 170 is closed.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
