Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a filtration device for purifying copper foil coupling agent solution. Background Technology

[0002] Coupling agents play a crucial role in copper foil preparation. They form an inorganic compound coating on the copper foil surface, protecting it from oxidation and facilitating adhesion. However, during preparation, impurities can be introduced due to manufacturing defects and raw material purity. For example, in the production of common silane coupling agents, insufficient purity of the raw monomer (such as chlorosilane) can lead to residual impurities. Incomplete hydrolysis during synthesis or improper post-processing (such as insufficient filtration or improper drying temperature control) can also introduce impurities. Impurities in the coupling agent solution can contaminate the copper foil, causing defects and affecting the quality of copper foil preparation, resulting in deficiencies in the copper foil manufacturing process. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a filtration device for purifying copper foil coupling agent solution. This device is used to filter impurities in the coupling agent, preventing impurities from contaminating the copper foil and affecting its quality during the use of the coupling agent. It can also be used to clean and discharge the filtered impurities, avoiding the accumulation of impurities that affect the use of this filtration device. This can effectively solve the problems in the background art.

[0015] 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.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a filtration device for purifying copper foil coupling agent solution, including a filter tank 1. A three-way valve 2 connected to the inner cavity of the filter tank 1 is installed at the bottom of the filter tank 1. A liquid inlet component is installed at one end of the three-way valve 2, and a drain component is installed at the other end of the three-way valve 2. A drain component connected to the inner cavity is installed on the upper side of the filter tank 1. In use, the coupling agent solution is added into the filter tank 1 through the liquid inlet component. After being filtered in the filter tank 1, the coupling agent solution is discharged from the filter tank 1 through the drain component. It is used for the production and preparation of copper foil. By filtering impurities in the coupling agent solution, the impact of impurities on the preparation of copper foil is reduced, ensuring the quality of copper foil preparation. The impurities filtered from the coupling agent solution can be discharged through the drain component, which facilitates the use of this filtration device.

[0017] The filter tank 1 is equipped with a filter screen 6 and a protective net 7. A filter element 5 is placed between the filter screen 6 and the protective net 7. Both the filter screen 6 and the protective net 7 are annular structures. The filter screen 6 and the protective net 7 constrain and limit the position of the filter element 5 to prevent displacement during use. The coupling agent solution entering the filter tank 1 is first filtered by the filter screen 6. The filter screen 6 is used to filter some solid impurities in the coupling agent solution, thereby reducing the clogging caused by solid impurities to the filter element 5 and improving the service life of the filter element 5. The coupling agent solution after being filtered by the filter screen 6 is then filtered by the filter element 5 and then discharged into the containment space between the protective net 7 and the filter tank 1. The filtered coupling agent solution can be discharged from the filter tank 1 through the drainage component, which facilitates the use of the coupling agent.

[0018] The liquid inlet assembly includes a liquid inlet pipe 3 installed inside the three-way valve 2, and a liquid inlet valve 4 installed on the liquid inlet pipe 3. The liquid outlet assembly includes a liquid outlet pipe 8 installed on the upper side of the filter tank 1 and communicating with the inner cavity of the filter tank 1, and a liquid outlet valve 9 installed on the liquid outlet pipe 8. When filtering the coupling agent, after opening the liquid inlet valve 4, the coupling agent can be delivered into the filter tank 1 through the liquid inlet pipe 3. At the same time, opening the liquid outlet valve 9 can discharge the filtered coupling agent through the liquid outlet pipe 8.

[0019] The sewage discharge assembly includes a sewage discharge pipe 18 installed in the three-way valve 2. A sewage discharge valve 19 is installed on the sewage discharge pipe 18. When it is necessary to discharge foreign matter filtered out by the filter screen 6, the inlet valve 4 on the inlet pipe 3 and the sewage discharge valve 9 on the drain pipe 8 are closed. Then, the sewage discharge valve 19 on the sewage discharge pipe 18 is opened. The coupling agent remaining in the filter tank 1 flows in the opposite direction to flush some of the foreign matter on the side of the filter screen 6 and the filter element 5. At the same time, the remaining coupling agent solution carries the flushed foreign matter out through the drain pipe 8.

[0020] A cleaning assembly is installed inside the filter tank 1, and a drive assembly is installed on the upper side of the filter tank 1 to drive the cleaning assembly to move up and down. The cleaning assembly includes a cleaning plate 12, the outer side of which contacts the side of the filter screen 6. A water spray tank 13 is installed on the lower side of the cleaning plate 12. Several sets of nozzles 14 communicating with its inner cavity are installed on the side of the water spray tank 13, and the nozzles 14 are set towards the filter screen 6. When it is necessary to clean the impurities on the filter screen 6, the inlet valve 4 and the outlet valve 9 are closed, and then the drain valve 19 is opened. The cleaning plate 12 is controlled to move down through the drive assembly. First, the cleaning liquid in the water spray tank 13 is controlled to spray out through the nozzles 14 to rinse the impurities filtered by the filter screen 6. Then the cleaning plate 12 cleans the filter screen 6, improving the quality of impurity cleaning. The cleaned impurities are discharged through the drain pipe 18 along with the cleaning liquid.

[0021] The drive assembly includes a connecting pipe 11 and a threaded cylinder 10 mounted on the upper side of the filter tank 1. The connecting pipe 11 has threads on its outer side that are compatible with the threaded cylinder 10. The bottom end of the connecting pipe 11 is fixed to the side of the cleaning plate 12 and communicates with the inner cavity of the spray tank 13. A water inlet pipe 16 is rotatably installed at the top end of the connecting pipe 11, and a handle 17 is installed on the upper side of the connecting pipe 11. During use, cleaning fluid is injected into the connecting pipe 11 through the water inlet pipe 16. The cleaning fluid enters the spray tank 13 through the connecting pipe 11 and is sprayed out through the nozzle 14. During this process, the connecting pipe 11 can be rotated by the handle 17. Under the action of the threads of the threaded cylinder 10, the connecting pipe 11 drives the cleaning plate 12 and the spray tank 13 to rotate and move downward, thereby improving the cleaning quality of impurities at the filter screen 6. By cleaning the impurities, it is prevented that the impurities accumulate and clog the filter screen 6, thus affecting the use of this filtration device.

[0022] A sealing gasket 15 is fixed on the upper side of the cleaning plate 12. After cleaning the filter screen 6, rotate the connecting pipe 11 to raise the cleaning plate 12 to the top of the filter tank 1. The sealing gasket 15 plays a sealing role, which facilitates the subsequent filtration of the coupling agent solution through this filtration device.

[0023] This copper foil coupling agent solution purification filtration device is used to filter impurities in the coupling agent, preventing impurities from contaminating the copper foil and affecting its quality during use. It can also be used to clean and discharge the filtered impurities, avoiding the accumulation of impurities that could affect the use of this filtration device.
