Description

Technical Field

[0001] This utility model relates to the field of additive filtration technology, specifically to an additive multi-stage gradient filtration device. Background Technology

[0002] The main function of the electrolytic copper foil additive dosing device is to automatically and precisely add additives to the electrolyte, thereby controlling key indicators such as roughness, peel strength, and tensile strength of the copper foil, and thus improving the overall quality of the copper foil product. In the additive dosing system of the electrolyte preparation workshop, workers first prepare the additive adhesive in a 316 stainless steel mixing tank, and then use a centrifugal pump to transfer the prepared additive to a PVC storage tank. By pre-setting the parameters of the metering pump controller, the metering pump can draw the additive from the storage tank at regular intervals and deliver it to a precision filter. During this process, the additive is thoroughly mixed with the electrolyte, thus achieving precise additive dosing.

[0003] However, existing technologies have some problems in practical applications: due to the complexity of the adhesive preparation process, the variability of raw materials, and the influence of external factors such as weather and environment, impurities and flocculent matter often mix into the formulated additives. These impurities and flocculent matter not only increase the operating burden of precision filters and significantly shorten the service life of their filter elements, but also easily accumulate in pipelines, even causing pipeline blockage in severe cases. More seriously, once a small amount of impurities and flocculent matter enters the electrolytic cell with the electrolyte, it will directly affect the quality of the copper foil, causing the copper foil to be scrapped or downgraded, thus causing economic losses to the company. To address this, a multi-stage gradient filtration device for additives is provided. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model, through the configuration of a wound filter, an inner filter plate, and a filter cylinder, enables the following process in the multi-stage gradient filtration device for additives: when the additive in the mixing tank is pumped into the wound filter by a centrifugal pump, after the first stage of filtration by the wound filter, it is sent into the outer shell of the cylinder through the discharge pipe. Then, the additive undergoes a second stage of filtration through the inner filter plate, and then enters the upper part of the inner filter plate. It then undergoes a third stage of filtration through the circumferential filter mesh of the filter cylinder, and enters the interior of the filter cylinder. Finally, it enters the storage tank for storage through the discharge hole.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-4 This utility model provides a technical solution: an additive multi-stage gradient filtration device, including: a mixing tank 1 and a storage tank 4. The mixing tank 1 is a container used for storing and initially mixing additives in the additive multi-stage gradient filtration device, and includes a stirring device such as a stirring motor, a stirring shaft and a stirring paddle. The storage tank 4 is used to store the additives after multi-stage gradient filtration, and is also equipped with a stirring device to prevent additive sedimentation and maintain uniformity.

[0023] A centrifugal pump 2 is installed at one end of the discharge port of the mixing tank 1. Connected to the discharge port, the centrifugal pump 2 provides power to the additives in the mixing tank 1, drawing them out and transporting them to subsequent filtration components. It is a key power source for the flow of additives within the device, ensuring their smooth entry into the filtration process. A wound filter 3 is also installed at one end of the discharge port of the centrifugal pump 2. Connected to the discharge port, the wound filter 3 receives the additives delivered by the centrifugal pump 2. As a first-stage filtration component, it initially filters out larger particles of impurities in the additives, reducing the burden on subsequent filtration components, extending their service life, and improving the overall filtration effect.

[0024] A guide pipe 5 is provided at one end of the outlet of the wire-wound filter 3. The guide pipe 5 connects to the outlet of the wire-wound filter 3 and guides the flow direction of the additive, accurately delivering the additive after the first stage of filtration by the wire-wound filter 3 to the next stage, ensuring the orderly flow of the additive within the device. A discharge pipe 6 is provided on one side of the guide pipe 5, connected to the guide pipe 5. The discharge pipe 6 leads the additive from the guide pipe 5 and delivers it into the cylindrical shell 9. It is an important channel connecting the guide pipe 5 and the cylindrical shell 9, allowing the additive to smoothly enter the second stage of filtration. A fixing pipe 7 is provided on one side of the top of the glue storage tank 4. The fixing pipe 7 is located on the top side of the glue storage tank 4, providing a fixed position for subsequent connections to the cylindrical shell 9 and other related components. It acts as a bridge connecting the filtration section and the glue storage tank 4, ensuring the stability and continuity of the entire device structure.

[0025] The top end of the fixed tube 7 is provided with a sealing cap 8, which is connected to the top end of the fixed tube 7 to seal and prevent the additive from leaking during the filtration process, ensuring the stability of the internal pressure of the device and the airtightness of the filtration environment, while providing a foundation for the installation and fixation of the internal filter components.

[0026] The sealing cover 8 has a cylindrical outer shell 9 at its bottom, and a filter cylinder 11 is located in the center of the cylindrical outer shell 9. An inner filter plate 10 is located in the middle of the filter cylinder 11, and a discharge hole 12 is located in the center of the bottom of the cylindrical outer shell 9. The cylindrical outer shell 9 is fixed to the bottom of the sealing cover 8 and serves as the main container for the second and third stage filtration. It provides installation space for filter components such as the inner filter plate 10 and the filter cylinder 11, allowing the additive to undergo orderly filtration within it. The inner filter plate 10 is installed in the middle of the filter cylinder 11 as a second-stage filtration component. After the additive enters the cylindrical outer shell 9 from the discharge pipe 6, it first passes through the inner filter plate 10 for filtration, removing larger impurities and providing a purer additive for the subsequent third-stage filtration, thus reducing the filtration burden on the filter cylinder 11. The filter cylinder 11, located in the center of the cylindrical outer shell 9, is a key component of the third-stage filtration. Its special structure, with a closed bottom and filter mesh at the top, allows the additive that has undergone second-stage filtration to undergo further fine filtration through its circumferential filter mesh, improving filtration accuracy. The discharge port 12 is located at the center of the bottom of the cylindrical shell 9 and below the inner side of the filter cylinder 11. The additives after three-stage filtration can flow smoothly into the storage tank 4 through the discharge port 12 for storage. It is the channel for the filtered additives to enter the storage tank 4, ensuring the integrity and continuity of the entire filtration process.

[0027] One end of the discharge pipe 6 extends into the interior of the cylindrical shell 9 and is located below the inner filter plate 10. This connection method ensures that the additive from the feed pipe 5 can directly enter the area below the inner filter plate 10, allowing the additive to accurately pass through the inner filter plate 10 for secondary filtration, thus ensuring the rationality and orderliness of the filtration process.

[0028] The portion of the filter cylinder 11 located below the inner filter plate 10 is a closed cylinder, while the portion of the filter cylinder 11 located above the inner filter plate 10 has filter mesh openings. The closed lower part of the filter cylinder 11 prevents additives from entering the filter cylinder 11 directly from below without filtration, ensuring that the additives must be filtered by the inner filter plate 10 before passing through the upper filter mesh openings for a third stage of filtration. This structural design makes the filtration process more rigorous and orderly, improving the filtration effect.

[0029] The diameter of the filter mesh on the filter cylinder 11 is smaller than that on the filter mesh on the inner filter plate 10. This design creates a multi-stage gradient filtration. The inner filter plate 10 first filters out larger particulate impurities, and then the filter cylinder 11 filters out smaller particulate impurities, gradually improving the filtration precision. This can more effectively filter out impurities and flocculent matter of different particle sizes in the additive, thereby improving the purity of the additive.

[0030] The bottom end of the filter cylinder 11 is fixed to the inner wall of the bottom of the outer casing 9, and the top end is fixed to the inside of the sealing cover 8. The inner filter plate 10 is annular, with its inner ring fixed to the outer wall of the filter cylinder 11 and its outer ring fixed to the inner wall of the outer casing 9. This fixing method ensures the stability of the filter cylinder 11 within the outer casing 9, preventing it from shaking or shifting due to the flow of additives and pressure changes during operation, thus ensuring the normal operation of the filtration process and the stability of the filtration effect.

[0031] The discharge port 12 is located on the lower inner side of the filter cylinder 11. This allows the additives after three-stage filtration to smoothly converge at the discharge port 12 and flow into the glue storage tank 4, ensuring that the filtered additives can be completely discharged from the outer shell 9 of the cylinder, avoiding residues inside the outer shell 9, and improving the efficiency of the filtration device and the utilization rate of the additives.

[0032] When the additive multi-stage gradient filtration device is used, the additive in the mixing tank 1 is sent into the wound filter 3 by the centrifugal pump 2. After the first stage of filtration by the wound filter 3, it is sent into the cylindrical shell 9 through the discharge pipe 6. Then, the additive is filtered through the inner filter plate 10 for the second stage and enters the upper part of the inner filter plate 10. It is then filtered through the circumferential filter mesh of the filter cylinder 11 for the third stage and enters the interior of the filter cylinder 11. Finally, it enters the storage tank 4 through the discharge hole 12 for storage.

[0033] Three filtrations remove most of the impurities and flocculent matter in the additives, thereby reducing the workload of subsequent precision filter elements, increasing their service life, reducing the risk of pipe blockage, minimizing the impact of impurities and flocculent matter in the additives on copper foil production, and reducing losses.

[0034] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
