Description

Technical Field

[0001] This invention relates to the field of copper dissolution technology using electrolytic solutions, and particularly to an additive-mixed connector, and more specifically to an additive-mixed connector and its method of use. Background Technology

[0002] Currently, in the lithium-ion battery copper foil industry, adding appropriate additives to the electrolyte can increase cathode polarization to varying degrees, thereby inhibiting abnormal metal growth. This is beneficial for obtaining dense cathode deposits and improving the elasticity, strength, hardness, and smoothness of the copper foil. Before reaching the foil-making machine, the additives need to be thoroughly mixed with the electrolyte, and the content of each additive must reach the required production level to maximize the quality of the produced foil. In existing technologies, traditional industrial production involves directly adding additives, leading to uneven additive content and insufficient mixing, resulting in poor electrolyte quality and a decline in the quality of the produced copper foil. Summary of the Invention

[0003] The technical problem to be solved by this invention is to overcome the defects of the prior art and provide an additive mixing connector. This invention changes the traditional method of directly adding additives. The additive is fed into the inner cavity of the outer shell through an additive addition pipe along a rotating blade. The spiral rotation of the blade causes the additive to disperse and contact with the electrolyte, which helps to accelerate the mixing of the additive and the electrolyte. The electrolyte mixture in the additive mixing pipe is then fed back into the high-level tank through the electrolyte outlet pipe and finally enters the pipeline of the next process. This ensures that the additive in the electrolyte outlet pipe is uniformly mixed, effectively solving the problems of uneven additive content and insufficient mixing, greatly improving the quality of the electrolyte and the quality of the copper foil.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] This invention discloses an additive mixing connector, comprising a first flange, a second flange, and a third flange. The first flange is installed and connected to one end of an electrolyte inlet pipe, which is inserted through the central cavity of a housing. A rotating blade is provided on the outside of the electrolyte inlet pipe. An additive inlet port is provided near one end of the first flange, and an additive inlet pipe is connected to the outside of the additive inlet port. The second flange is installed at the end of the additive inlet pipe. A mixture outlet pipe is connected to the bottom side wall of the housing, and the third flange is installed at the end of the mixture outlet pipe. An inlet ring is connected to one end of the third flange and is installed in the inner cavity of the electrolyte outlet pipe. The outer wall of the electrolyte outlet pipe has a mixture inlet port extending through it.

[0006] As a preferred embodiment of the present invention, the rotating blade is manufactured by rotating along the electrolyte inlet tube, and the rotating blade has a constant pitch of 90-110 mm and rotates 3-8 times.

[0007] As a preferred embodiment of the present invention, the additive adding tube is bent at a right angle and extends outward, and several additive adding tubes are evenly distributed on the outside of the outer shell.

[0008] As a preferred embodiment of the present invention, the first flange, the additive addition pipe, the second flange, the outer shell, the rotating blade, and the electrolyte addition pipe together constitute the additive mixing pipe.

[0009] As a preferred embodiment of the present invention, one end of the additive mixing tube is connected to one end of the electrolyte outlet tube through a high-level tank.

[0010] As a preferred embodiment of the present invention, the additive mixing tube is made of stainless steel, and the outer diameter of the outer shell is 180 mm and the length is 500 mm. The size of the electrolyte inlet tube is DN50 mm, and the size of the mixture outlet tube is DN50 mm.

[0011] As a preferred embodiment of the present invention, the inner diameter of the adding ring is larger than the outer diameter of the electrolyte outlet pipe.

[0012] As a preferred embodiment of the present invention, the mixed liquid inlet is at a 30° angle to the electrolyte outlet pipe, and a total of 6 mixed liquid inlets are evenly distributed.

[0013] A method for using an additive-mixed connector, and the steps of the method for using the additive-mixed connector are as follows:

[0014] Step 1: Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 5 When referring to the attached diagrams, rotate them 90° clockwise for easier understanding; once the entire structure of the additive mixing connector is connected, the high-level tank, additive mixing pipe, addition ring, and electrolyte outlet pipe form a dynamic flow.

[0015] Step Two: When the electrolyte introduced into one end of the high-level tank passes through the first flange and re-enters the electrolyte inlet pipe, it enters the inner cavity of the outer shell. At the same time, the additives flow from the second flange and the additive inlet pipe onto the rotating blades. On the one hand, with initial flow kinetic energy when the additives enter the additive inlet pipe, the additives will be surrounded by the electrolyte inlet pipe by the rotating blades and gradually flow into the inner cavity of the other end of the outer shell. On the other hand, in the specific installation of the additive mixing connector, the additive mixing pipe can be kept in a vertically downward connection state. Under the action of gravity, the additives flowing from the second flange and the additive inlet pipe onto the rotating blades will flow freely downwards around the electrolyte inlet pipe and finally enter the inner cavity of the other end of the outer shell.

[0016] Step 3: During the encapsulation process, the electrolyte permeates through the gaps between the rotating blades and floods the surface of the rotating blades; at this time, the introduced additive will flow along the blade path of the rotating blades, so that the additive is evenly dispersed on the rotating blades in the inner cavity enclosed by the outer shell, allowing the additive and electrolyte to be fully mixed inside the outer shell.

[0017] Step 4: After step 3, the fully mixed additive mixture enters the inlet ring through the mixture outlet pipe and the third flange. There are 6 mixture inlet ports evenly distributed on the inside of the inlet ring and on the electrolyte outlet pipe. The mixture then enters the electrolyte outlet pipe again. The electrolyte outlet pipe transports the additive mixture after passing through the additive mixing pipe to the high-level tank at the other end, and finally into the pipeline of the next process.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] This invention changes the traditional method of directly adding additives. The additive is fed into the inner cavity of the outer shell through an additive addition tube along a rotating blade. The spiral rotation of the blade disperses and contacts the additive with the electrolyte, which helps to accelerate the mixing of the additive and the electrolyte. The electrolyte mixture in the additive mixing tube is then fed back into the high-level tank through the electrolyte outlet tube and finally enters the pipeline of the next process. This ensures that the additive in the electrolyte outlet tube is uniformly mixed, effectively solving the problems of uneven additive content and insufficient mixing, greatly improving the quality of the electrolyte and the quality of the copper foil.

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] Example 1

[0030] like Figure 1-6 As shown, the present invention provides an additive mixing connector, including a first flange 1, a second flange 3, and a third flange 7. The first flange 1 is installed and connected to one end of an electrolyte inlet pipe 6, which is inserted through the central cavity of the outer shell 4. A rotating blade 5 is provided on the outside of the electrolyte inlet pipe 6. An additive inlet port 12 is provided near one end of the first flange 1, and an additive inlet pipe 2 is connected to the outside of the additive inlet port 12. A second flange 3 is installed at the end of the additive inlet pipe 2. A mixture outlet pipe 8 is connected to the bottom side wall of the outer shell 4, and a third flange 7 is installed at the end of the mixture outlet pipe 8. An inlet ring 9 is connected to one end of the third flange 7. The inlet ring 9 is installed in the inner cavity of the electrolyte outlet pipe 11, and a mixture inlet port 10 is provided through the outer wall of the electrolyte outlet pipe 11.

[0031] The rotating blade 5 is made by rotating along the electrolyte addition pipe 6, forming a trajectory channel for the flow of additives, which is beneficial for dispersion; and the rotating blade 5 has a constant pitch of 90-110 mm and rotates 3-8 times.

[0032] The additive addition tube 2 is bent at a right angle and extends outward. Several additive addition tubes 2 are evenly distributed on the outside of the outer shell 4, which meets the design requirements of the structure.

[0033] The first flange 1, the additive inlet pipe 2, the second flange 3, the outer shell 4, the rotating blade 5, and the electrolyte inlet pipe 6 together constitute the additive mixing pipe 14. Through the addition of the new design structure, the unevenness caused by the traditional direct addition of additives in the industry is effectively solved.

[0034] One end of the additive mixing tube 14 is connected to one end of the electrolyte outlet tube 11 through the high-level tank 13, forming a dynamic flow channel.

[0035] The additive mixing tube 14 is made of stainless steel, and the outer diameter of the outer shell 4 is 180 mm and the length is 500 mm. The electrolyte inlet tube 6 is DN50 mm in size, and the mixed liquid outlet tube 8 is DN50 mm in size.

[0036] The inner diameter of the added ring 9 is larger than the outer diameter of the electrolyte outlet tube 11, as per the instruction manual. Figure 4 As shown, when the inner diameter of the inlet ring 9 is larger than the outer diameter of the electrolyte outlet pipe 11, a gap cavity will be formed. The inlet ring 9 is sealed and installed on the side of the electrolyte outlet pipe 11.

[0037] The inlet 10 of the mixture is at a 30° angle to the outlet pipe 11 of the electrolyte, and the 30° tilt direction is aligned with the direction of the additive mixture outflow (i.e., the other end of the high-level tank 13). At this time, under the premise that the additive mixture originally has the kinetic energy of flow, it is thrown in the opposite direction of the flow direction of the electrolyte outlet pipe 11, which further enhances the mixing effect of the additive and the electrolyte.

[0038] Furthermore, there are a total of 6 mixture inlets 10 evenly distributed, forming a gap cavity. The inlet ring 9 is sealed and installed on the side of the electrolyte outlet pipe 11, so that the additive mixture is injected into the electrolyte outlet pipe 11 through the 6 mixture inlets 10.

[0039] A method for using an additive-mixed connector, and the steps of the method for using the additive-mixed connector are as follows:

[0040] Step 1: Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 5 When referring to the attached diagrams, rotate each diagram 90° clockwise for easier understanding; once the entire structure of the additive mixing connector is connected, the high-level tank 13, additive mixing pipe 14, addition ring 9, and electrolyte outlet pipe 11 form a dynamic flow.

[0041] Step 2: When the electrolyte introduced into one end of the high-level tank 13 passes through the first flange 1 and re-enters the electrolyte inlet pipe 6, it enters the inner cavity of the outer shell 4. At the same time, the additives flow from the second flange 3 and the additive inlet pipe 2 onto the rotating blade 5. On the one hand, under the condition that the additives have initial flow kinetic energy when they enter the additive inlet pipe 2, the additives will be surrounded by the electrolyte inlet pipe 6 by the rotating blade 5 and gradually flow into the inner cavity of the other end of the outer shell 4. On the other hand, in the specific installation of the additive mixing connector, the additive mixing pipe 14 can be kept in a vertically downward connection state. Under the action of gravity, the additives flowing from the second flange 3 and the additive inlet pipe 2 onto the rotating blade 5 will flow freely downward around the electrolyte inlet pipe 6 and finally enter the inner cavity of the other end of the outer shell 4.

[0042] Step 3: During the process of encapsulating the outer shell 4, the electrolyte permeates through the gaps between the rotating blades 5 and floods the surface of the rotating blades 5; at this time, the introduced additive will flow along the blade path of the rotating blades 5, so that the additive is evenly dispersed on the rotating blades 5 in the inner cavity encapsulated by the outer shell 4, allowing the additive and electrolyte to be fully mixed in the outer shell 4.

[0043] Step 4: After step 3, the fully mixed additive mixture enters the inlet ring 9 through the mixture outlet pipe 8 and the third flange 7. Then, six mixture inlets 10 are evenly distributed on the inside of the inlet ring 9 and on the electrolyte outlet pipe 11, and the mixture enters the electrolyte outlet pipe 11 again. The electrolyte outlet pipe 11 transports the additive mixture after passing through the additive mixing pipe 14 to the high-level tank 13 at the other end, and finally into the pipeline of the next process.

[0044] Working principle: When the electrolyte introduced into one end of the high-level tank 13 passes through the first flange 1 and re-enters the electrolyte inlet pipe 6, it enters the inner cavity of the outer shell 4. The additives flow from the second flange 3 and the additive inlet pipe 2 onto the rotating blade 5. Under the condition that the additives have initial flow kinetic energy when they enter the additive inlet pipe 2, the additives will be surrounded by the rotating blade 5 around the electrolyte inlet pipe 6 and gradually flow into the inner cavity of the other end of the outer shell 4. Alternatively, in the specific installation of the additive mixing connector, the additive mixing pipe 14 can be kept in a vertically downward connection state. Under the action of gravity, the additives flowing from the second flange 3 and the additive inlet pipe 2 onto the rotating blade 5 will flow freely downward around the electrolyte inlet pipe 6 and finally enter the inner cavity of the other end of the outer shell 4. During the encapsulation process of 4, the electrolyte permeates through the gaps in the rotating blades 5 and submerges the surface of the rotating blades 5. At this time, the introduced additive flows along the blade path of the rotating blades 5, so that the additive is evenly dispersed on the rotating blades 5 in the inner cavity enclosed by the outer shell 4, allowing the additive and electrolyte to be fully mixed in the outer shell 4. The fully mixed additive mixture enters the inlet ring 9 through the mixture outlet pipe 8 and the third flange 7, and then enters the electrolyte outlet pipe 11 again through a total of 6 mixture inlet ports 10 evenly distributed on the inner side of the inlet ring 9 and the electrolyte outlet pipe 11. The electrolyte outlet pipe 11 then transports the additive mixture after passing through the additive mixing pipe 14 to the high-level tank 13 at the other end, and finally into the pipeline of the next process.
