Description

Technical Field

[0001] This utility model relates to the field of electrolytic copper foil production technology, and in particular to an electrolyte circulation structure for a copper melting tank used in the production of electrolytic copper foil. Background Technology

[0002] Electrolytic copper foil is an important conductor raw material in the manufacture of copper-clad laminates, printed circuit boards, flexible circuit boards, and lithium-ion batteries, and is widely used in electronics, communications, computers, and other fields. In the production of electrolytic copper foil, the copper dissolution process is the first step, also known as electrolyte preparation. Its purpose is to dissolve the copper raw material into a sulfate solution so that copper ions can be reduced on the surface of the cathode plate to form copper foil.

[0003] In existing technologies, heating or stirring of the solution is usually required to accelerate the copper dissolution process. However, existing small-scale heating equipment in laboratories cannot guarantee uniform heating of the solution, resulting in uneven and unstable reaction between the solution and the copper material. Stirring can also cause copper to accumulate in certain areas of the solution, preventing uniform distribution and affecting the dissolution rate. Therefore, this paper proposes an improved electrolyte circulation structure for the copper dissolution tank in the production of electrolytic copper foil. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose an electrolyte circulation structure for a copper melting tank in the production of electrolytic copper foil, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides an electrolyte circulation structure for a copper melting tank in the production of electrolytic copper foil, comprising a copper melting tank, a plurality of feed pipes provided on the copper melting tank, a discharge pipe provided on the copper melting tank, a main shaft rotatably connected inside the copper melting tank, a motor with an output shaft fixedly connected to the main shaft provided on the copper melting tank, a main spiral disk fixedly connected to the main shaft, a plurality of horizontal plates fixedly connected to the main shaft, and a secondary shaft rotatably connected to the end of the horizontal plates, wherein a stirring plate is fixedly connected to a portion of the secondary shaft, and a secondary spiral disk is fixedly connected to another portion of the secondary shaft;

[0007] A driven gear is fixedly connected to the top of the countershaft. An internal gear ring that meshes with the driven gear is fixedly connected inside the copper melting tank. An electric heating plate is installed inside the copper melting tank. A side door is opened on the side wall of the copper melting tank. An anti-corrosion coating is applied to the electric heating plate.

[0008] Preferably, as described in any of the above embodiments, the copper melting tank is provided with support legs at the bottom, and the discharge pipe is located at the bottom of the copper melting tank.

[0009] Preferably, in any of the above embodiments, the ends of the feed pipe and the discharge pipe are provided with flanges, and the main shaft is rotatably connected to the center of the copper melting tank.

[0010] The above technical solution employs the following: The copper melting tank provides space for the copper melting operation and serves as an installation platform for related components. An inlet pipe is installed on the tank, allowing external steam, hot water, ion-exchange water, compressed air, and high-purity sulfuric acid to be fed into the melting tank, providing the necessary conditions for the copper melting process. The outlet pipe is used to discharge the generated copper sulfate solution from the melting tank. Support legs are installed at the bottom of the melting tank, and the outlet pipe is positioned at the bottom of the tank to facilitate the discharge of the copper sulfate solution from the bottom. Flanges are installed at the ends of both the inlet and outlet pipes for easy connection to external pipelines.

[0011] Preferably, in any of the above embodiments, the horizontal plate is fixedly connected to the upper part of the main shaft, and limit plates are provided on both the top and bottom surfaces of the horizontal plate on the secondary shaft.

[0012] Preferably, any of the above schemes has a plurality of stirring plates that are evenly arranged along the length of the secondary shaft.

[0013] The above technical solution employs a platform consisting of a horizontal plate and a main spiral disc. Starting the motor drives the main shaft to rotate, which in turn drives the main spiral disc, mixing the solution in the copper melting tank from bottom to top. Simultaneously, the rotation of the main shaft drives the horizontal plate, which in turn drives the auxiliary shaft. This auxiliary shaft, in conjunction with its stirring plate, promotes horizontal mixing of the solution in the copper melting tank. This ensures thorough contact between the solution and the copper components, accelerating the copper melting process.

[0014] Preferably, in any of the above embodiments, the driven gear is positioned above the horizontal plate, and the heating plate has a ring structure.

[0015] Preferably, in any of the above embodiments, the heating plate with a ring structure has a notch at the side door, and a sealing assembly is provided between the side door and the copper melting tank.

[0016] The above technical solution works as follows: Under the action of the driven gear and the internal gear ring, when the main shaft drives the horizontal plate and the secondary shaft to rotate, the secondary shaft is driven by the driven gear to rotate on its own axis. In this way, the secondary spiral disk on the secondary shaft can drive the solution at the secondary shaft to mix upwards. The stirring plate on the secondary shaft can better mix the solution during its revolution and rotation, thus further increasing the copper dissolving speed. The heating plate can heat the solution in the copper dissolving vessel, allowing the temperature of the solution in the vessel to be adjusted as needed.

During operation, copper material is added to the melting tank through a side door. The tank is connected to an external supply pipe via a feed pipe, allowing the addition of steam, hot water, ion-exchange water, compressed air, and high-purity sulfuric acid. During the reaction, the motor is started, driving the main shaft to rotate. The main shaft then drives the main spiral disc, mixing the solution in the melting tank from bottom to top. Simultaneously, the rotation of the main shaft drives the horizontal plate, which in turn drives the secondary shaft. The secondary shaft, in conjunction with its stirring plate, promotes horizontal mixing of the solution in the melting tank. Under the action of the driven gear and internal gear ring, when the main shaft drives the horizontal plate and the secondary shaft to rotate, the secondary shaft is driven by the driven gear to rotate on its own axis. In this way, the secondary spiral disk on the secondary shaft can drive the solution at the secondary shaft upwards for mixing. The stirring plate on the secondary shaft can better mix the solution during its revolution and rotation, thus further increasing the copper dissolving speed. The heating plate can heat the solution in the copper dissolving tank, allowing the temperature of the solution in the tank to be adjusted as needed. More uniform solution heating, more thorough contact between the solution and the copper material, and easier control of the solution temperature all contribute to the rapid progress of the copper dissolving process.

[0029] like Figures 1-4 As shown, this utility model includes a copper melting tank 1, a plurality of feed pipes 2 and a discharge pipe 3 on the copper melting tank 1, a main shaft 4 rotatably connected inside the copper melting tank 1, a motor 5 with an output shaft fixedly connected to the main shaft 4 on the copper melting tank 1, a main spiral disk 6 fixedly connected to the main shaft 4, a plurality of horizontal plates 7 fixedly connected to the main shaft 4, and a secondary shaft 8 rotatably connected to the end of the horizontal plates 7, wherein a stirring plate 9 is fixedly connected to a part of the secondary shaft 8, and a secondary spiral disk 10 is fixedly connected to another part of the secondary shaft 8;

[0030] A driven gear 11 is fixedly connected to the top of the countershaft 8. An internal gear ring 12 that meshes with the driven gear 11 is fixedly connected inside the copper melting tank 1. An electric heating plate 13 is provided inside the copper melting tank 1. A side door 14 is opened on the side wall of the copper melting tank 1. An anti-corrosion coating is applied to the electric heating plate 13.

[0031] Example 1: The copper melting tank 1 is equipped with support legs at its bottom, and the discharge pipe 3 is located at the bottom of the copper melting tank 1. Flanges are installed at the ends of both the inlet pipe 2 and the discharge pipe 3. The main shaft 4 is rotatably connected to the center of the copper melting tank 1. The copper melting tank 1 provides space for copper melting operations and a platform for installing related components. The inlet pipe 2 is installed on it, allowing external steam, hot water, ion-exchange water, compressed air, and high-purity sulfuric acid to be input into the copper melting tank 1, providing the necessary conditions for copper melting operations. The discharge pipe 3 is used to discharge the generated copper sulfate solution from the copper melting tank 1. The support legs at the bottom of the copper melting tank 1 and the location of the discharge pipe 3 at the bottom of the copper melting tank 1 facilitate the discharge of the copper sulfate solution from the bottom of the copper melting tank 1. Flanges are installed at the ends of the inlet pipe 2 and the discharge pipe 3 for easy connection to external pipelines.

[0032] Example 2: The horizontal plate 7 is fixedly connected to the upper part of the main shaft 4. Limiting plates are provided on the top and bottom surfaces of the horizontal plate 7 on the secondary shaft 8. Several stirring plates 9 are evenly arranged along the length of the secondary shaft 8. The main shaft 4 provides an installation platform for the horizontal plate 7 and the main spiral disk 10. The motor 5 is started, and the motor 5 drives the main shaft 4 to rotate. The main shaft 4 drives the main spiral disk 10 to rotate, which can mix the solution in the copper melting tank 1 from bottom to top. When the main shaft 4 rotates, it synchronously drives the horizontal plate 7 to rotate, which in turn drives the secondary shaft 8 to rotate. The secondary shaft 8, together with the stirring plates 9 on it, can mix the solution in the copper melting tank 1 in a horizontal direction. This can achieve full contact between the solution and the copper parts, and make the copper melting process faster.

[0033] Example 3: The driven gear 11 is positioned above the horizontal plate 7, and the heating plate 13 adopts a ring structure. The ring-shaped heating plate 13 has a notch at the side door 14, and a sealing assembly is provided between the side door 14 and the copper melting tank 1. Under the action of the driven gear 11 and the internal gear ring 12, when the main shaft 4 drives the horizontal plate 7 and the secondary shaft 8 to rotate, the secondary shaft 8 is driven by the driven gear 11 to rotate. Thus, the secondary spiral disk 10 on the secondary shaft 8 can drive the solution at the secondary shaft 8 to mix upwards. The stirring plate 9 on the secondary shaft 8 can better mix the solution during its revolution and rotation, thereby further increasing the copper melting speed. The heating plate 13 can heat the solution in the copper melting tank 1, thus allowing the temperature of the solution in the copper melting tank 1 to be adjusted as needed.

[0034] The working principle of this utility model is as follows:

[0035] S1. Add copper material into copper melting tank 1 through side door 14. Connect the feed pipe 2 to the external feed pipe and add steam hot water, ion exchange water, compressed air and high-purity sulfuric acid into copper melting tank 1.

[0036] S2. During the reaction, motor 5 is started, which drives the main shaft 4 to rotate. The main shaft 4 drives the main spiral disk 10 to rotate, which can mix the solution in the copper dissolving tank 1 from bottom to top. When the main shaft 4 rotates, it simultaneously drives the horizontal plate 7 to rotate, which in turn drives the secondary shaft 8 to rotate. The secondary shaft 8, together with the stirring plate 9 on it, can mix the solution in the copper dissolving tank 1 horizontally. Under the action of the driven gear 11 and the internal gear ring 12, when the main shaft 4 drives the horizontal plate 7 and the secondary shaft 8 to rotate, the secondary shaft 8 is driven by the driven gear 11 to rotate on its own axis. In this way, the secondary spiral disk 10 on the secondary shaft 8 can mix the solution at the secondary shaft 8 upward. The stirring plate 9 on the secondary shaft 8 can better mix the solution during the revolution and rotation process, which can further improve the copper dissolving speed.

[0037] S3. As needed, use the heating plate 13 to control the temperature of the solution and promote the rapid progress of copper dissolution.

The tank is connected to an external supply pipe via the feed pipe 2, allowing the addition of steam, hot water, ion-exchange water, compressed air, and high-purity sulfuric acid. During the reaction, the motor 5 is started, driving the main shaft 4 to rotate. The main shaft 4 then drives the main spiral disc 10, causing the solution in the copper melting tank 1 to mix from bottom to top. Simultaneously, the rotation of the main shaft 4 drives the horizontal plate 7, which in turn drives the secondary shaft 8 to rotate. The secondary shaft 8, in conjunction with the stirring plate 9, causes the solution in the copper melting tank 1 to mix horizontally. Under the action of the driven gear 11 and the internal gear ring 12, when the main shaft 4 drives the horizontal plate 7 and the secondary shaft 8 to rotate, the secondary shaft 8 is driven by the driven gear 11 to rotate on its own axis. Thus, the secondary spiral disk 10 on the secondary shaft 8 can drive the solution at the secondary shaft 8 to mix upwards. The stirring plate 9 on the secondary shaft 8 can better mix the solution during its revolution and rotation, thereby further increasing the copper dissolving speed. The heating plate 13 can heat the solution in the copper dissolving tank 1, thus allowing the temperature of the solution in the copper dissolving tank 1 to be adjusted as needed.
