TECHNICAL FIELD

[0001] The present application relates to the technical field of electrolyte purification, specifically a magnesium-lithium alloy anodic oxidation electrolyte circulating purification device. BACKGROUND

[0002] Magnesium-lithium alloy is a lightweight and high-strength metal material, which has wide application prospects in aerospace, automobile manufacturing, electronics and other fields. Anodic oxidation is a common surface treatment method that can improve the corrosion resistance, wear resistance and decorative properties of magnesium-lithium alloy. However, during the anodic oxidation process, the electrolyte will gradually be contaminated, leading to a decrease in the quality of the oxidation film and even preventing normal anodic oxidation. Therefore, regular purification treatment of the electrolyte is needed to ensure the effectiveness of anodic oxidation.

[0003] Currently, traditional electrolyte purification methods mainly include filtration, precipitation, distillation, etc. These methods have the disadvantages of unsatisfactory purification effect, complex operation, high cost, etc. For example, filtration can only remove large particle suspended matter in the electrolyte, but it is difficult to remove small impurity ions and organic matter; precipitation method requires the addition of a large amount of chemical reagents, which can easily introduce new impurities; distillation method has high energy consumption and low production efficiency. In addition, existing electrolyte purification devices are mostly simple in structure and single in function, which cannot meet the purification requirements of magnesium-lithium alloy anodic oxidation electrolyte.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 A magnesium-lithium alloy anodic oxidation electrolyte circulation purification device includes a filter barrel 100, an inner mounting basket 200, a mounting column 300, a rotating rod 400, a barrel cover 500, an adsorption cylinder 600, and an ion exchange cylinder 700. The inner mounting basket 200 and the mounting column 300 are both fixedly installed inside the filter barrel 100. The mounting column 300 is located around the inner mounting basket 200. A cylinder frame 202 is inserted into the inner mounting basket 200. A coarse filter plate 204 is fixedly installed on the side of the cylinder frame 202. A fan-shaped frame 303 is provided in the mounting column 300, and a microporous filter membrane 305 is fixedly connected to the inner wall of the fan-shaped frame 303. The rotating rod 400 is located in the middle of the inner mounting basket 200, and a scraper 401 is fixedly connected to the surface of the rotating rod 400, with the scraper 401 in contact with the coarse filter plate 204. A connecting column 104 is fixedly connected to the bottom of the filter 100. The bottom of the connecting column 104 is fixedly connected to the top of the ion exchange cylinder 700. A support leg 701 is fixedly connected to the bottom of the ion exchange cylinder 700. Several connecting pipes 103 are fixedly connected to the bottom of the side wall of the filter 100.

The water inlet 501 is located directly above the cylinder frame 202. The electrolyte first passes through a coarse filter plate 204 to remove large particulate impurities, then undergoes fine filtration through a microporous membrane 305, followed by adsorption of organic matter in an adsorption cylinder 600, and finally removes ionic impurities in an ion exchange cylinder 700. This integrated design improves purification efficiency, avoids the cumbersome operation of multiple electrolyte transfers in traditional methods, and features a compact structure that saves space and facilitates deployment in industrial sites. The device recycles the electrolyte, helping to reduce resource consumption and operating costs.

[0021] Please see Figure 4 and Figure 5The inner wall of the mounting inner basket 200 is fixedly connected with a protruding strip 201, and the surface of the cylinder frame 202 has a groove 203, which slides and engages with the protruding strip 201. By adding the feature of sliding engagement between the protruding strip 201 on the inner wall of the mounting inner basket 200 and the groove 203 on the surface of the cylinder frame 202, the ease of installation and disassembly of the cylinder frame 202 is improved, making the cleaning or replacement of the coarse filter plate 204 faster and reducing maintenance downtime. The sliding engagement structure ensures that the cylinder frame 202 remains stable during operation, avoiding displacement due to vibration, thereby ensuring the continuity of the filtration effect.

[0022] Please see Figure 1 , Figure 2 , Figure 3 A motor 404 is fixedly connected to the bottom of the filter barrel 100. A hexagonal head 405 is fixedly connected to the output end of the motor 404. The hexagonal head 405 is located inside the filter barrel 100.

The rotating rod 400 and the scraper 401 are rotated by the motor. The scraper 401 is in contact with the coarse filter plate 204, which can promptly scrape off the attached impurities, prevent the filter plate from clogging, and reduce the frequency of manual cleaning. The plug-in design of the top block 402 and the protruding rod 503 facilitates the installation and alignment of the rotating rod 400, improving the reliability and automation level of the device.

[0023] Please see Figure 1 , Figure 4 and Figure 6 The fan-shaped frame 303 is arranged in a fan shape, with protruding strips 304 fixedly connected to both sides of the frame. A slot 301 is provided on the side of the mounting column 300, which slidably engages with the protruding strips 304. An insertion hole 302 is provided at the top of the mounting column 300. A protruding rod 504 is fixedly connected to the lower surface of the lid 500, and the protruding rod 504 is movably inserted into the insertion hole 302. The lid 500 abuts against the top of the fan-shaped frame 303. Through the fan-shaped arrangement of the frame 303, the sliding engagement of the protruding strips 304 and the slots 301, and the insertion of the lid 500 through the protruding rod 504 and the insertion hole 302, the fan-shaped design allows for quick replacement of the filter membrane, ensuring filtration accuracy. The fixing effect of the lid 500 enhances the overall structural rigidity and prevents leakage during operation. This design simplifies the maintenance process and improves the applicability of the device to different purification needs.

[0024] Please see Figure 1 , Figure 2 , Figure 3 andFigure 4 An activated carbon filter cartridge 601 is threadedly connected to the top of the adsorption cylinder 600. Activated carbon is placed inside the activated carbon filter cartridge 601. A sieve plate 603 is fixedly connected to the inner wall of the lower cylinder 602. Silica gel adsorption particles are placed in the cavity below the sieve plate 603 inside the adsorption cylinder 600. A filter screen is installed inside the end cap 604 to prevent the silica gel adsorption particles from falling out. Through the activated carbon filter cartridge 601, the sieve plate 603, and the silica gel adsorption particles, the activated carbon filter cartridge 601 can effectively remove organic matter and pigments from the electrolyte, while the silica gel adsorption particles further capture fine impurities. The threaded connection design facilitates the replacement of adsorption materials, extends the service life of the device, and ensures a hygienic and safe purification process.

[0025] Please see Figure 1 and Figure 8 Two filter screens 702 are fixedly connected inside the ion exchange cylinder 700. The two filter screens 702 are arranged vertically inside the ion exchange cylinder 700. A second partition screen 704 is fixedly connected to the bottom of the ion exchange cylinder 700. A cation exchange resin column is placed between the two filter screens 702. An anion exchange resin column is placed in the cavity above the second partition screen 704. An outlet 706 is fixedly connected to the bottom of the ion exchange cylinder 700. Two sealing doors 705 are fixedly installed on the side wall of the ion exchange cylinder 700. The two sealing doors 705 correspond to the positions of the cation exchange resin column and the anion exchange resin column, respectively. Filter covers 703 are fixedly connected below several sieve holes on the filter screens 702. By incorporating a filter screen 702, a partition screen 704, and cation and anion exchange resin columns, the cation exchange resin removes metal ions, while the anion exchange resin treats acid radicals, thereby restoring the chemical balance of the electrolyte. The layered arrangement improves exchange efficiency, and the filter screen 702 ensures uniform liquid distribution, preventing resin bed caking and enhancing purification stability. The addition of a closed door 705 on the sidewall of the ion exchange cylinder 700 provides direct access without disassembling the entire cylinder, reducing maintenance time and labor intensity while maintaining system sealing and preventing external contamination. The filter cover 703 below the sieve holes of the filter screen 702 acts as a secondary barrier, ensuring that resin particles are not washed away by the liquid, maintaining the integrity of the exchange bed, and thus improving purification continuity and equipment reliability.

[0026] Please see Figure 2 and Figure 3A flange 101 is fixedly connected to the top edge of the filter tank 100, and bolts 102 are inserted into the edge of the tank cover 500, with the bolts 102 being fixedly connected to the flange 101. The tank cover 500 is connected to the top of the filter tank 100 via the flange 101 and bolts 102. The flange connection ensures that the tank cover 500 is tightly fixed to prevent electrolyte leakage; the bolts 102 are designed for quick opening and closing, facilitating daily inspection and cleaning, and improving the overall safety of the device.

[0027] Working principle and usage steps: The electrolyte first enters the device through the inlet 501 at the top of the lid 500. The inlet 501 is located directly above the frame 202 to ensure uniform liquid distribution. After flowing into the inner basket 200, the electrolyte undergoes primary filtration through the coarse filter plate 204 on the side of the frame 202 to remove large suspended solids and impurities. The design of the coarse filter plate 204 improves processing efficiency and prevents clogging of subsequent components. Simultaneously, the rotating rod 400 rotates under the drive of the motor 404, and the scraper 401 on its surface adheres to the coarse filter plate 204, automatically scraping off attached impurities and keeping the filter plate unobstructed. The hexagonal head 405 at the output end of the motor 404 engages with the bottom block 403 at the bottom of the rotating rod 400 to ensure stable power transmission. The electrolyte, after primary filtration, flows from the periphery of the inner basket 200 to the mounting column 300. The mounting column 300 contains a fan-shaped frame 303, whose inner wall is fixed with a microporous filter membrane 305 for fine filtration, removing fine particles and colloidal substances. The modular design of the fan-shaped frame 303 facilitates filter membrane replacement and adapts to different purification needs. The electrolyte is further purified by the microporous filter membrane 305, ensuring liquid cleanliness. The lid 500 is inserted into the insertion hole 302 of the mounting column 300 via a second protrusion 504, enhancing structural sealing and preventing leakage. The electrolyte enters the adsorption cylinder 600 through the connecting pipe 103 at the bottom of the filter tank 100. An activated carbon filter 601 is threadedly connected to the top of the adsorption cylinder 600; the activated carbon inside adsorbs organic matter and pigments; the lower cavity contains silica gel adsorbing particles for further capture of fine impurities. The filter screens in the sieve plate 603 and the end cap 604 prevent the loss of adsorption material and ensure uniform purification effect. After adsorption, the electrolyte flows to the ion exchange cylinder 700 through the connecting pipe 605. After the electrolyte enters the ion exchange cylinder 700, it is first evenly distributed by the upper filter screen 702, then passes through the cation exchange resin column to remove metal ions, and finally through the anion exchange resin column to treat acid ions. The partition screen 704 and filter cover 703 prevent resin loss and ensure exchange efficiency. The purified electrolyte is discharged from the outlet 706 and can be recycled for the anodizing process. The sealed door 705 of the ion exchange cylinder 700 facilitates resin replacement and maintenance.

[0028] First, place the device on a stable surface, with the support leg 701 providing a stable foundation. Install the internal components of the filter cartridge 100: slide the cartridge frame 202 into the inner basket 200 via the groove 203, ensuring the coarse filter plate 204 is in place; engage the fan-shaped frame 303 with the mounting column 300 via the second protrusion 304, securing the microporous filter membrane 305 firmly. Connect the adsorption cartridge 600: thread the top of the adsorption cartridge 600 to the connecting pipe 103 of the filter cartridge 100, and thread the bottom end to the lower receiving cartridge 602 and the flavor end cap 604 in sequence. The activated carbon filter cartridge 601 and silica gel adsorption particles are pre-placed. Close the cartridge lid 500: secure it to the flange 101 of the filter cartridge 100 with bolts 102, inserting the second protrusion 504 into the insertion hole 302 to ensure a seal. Connect the power supply and start the motor 404. The motor drives the rotating rod 400 to rotate, and the scraper 401 begins cleaning the coarse filter plate 204. Inject the magnesium-lithium alloy anodized electrolyte to be purified through inlet 501. The liquid flows naturally, passing through primary and fine filtration. Monitor electrolyte flow: adjust the flow rate via PLC controller to avoid overload. Observe the pressure indicators of adsorption cylinder 600 and ion exchange cylinder 700 to ensure no blockage. The electrolyte removes organic matter during the adsorption stage and restores chemical balance during the ion exchange stage. Regularly check the electrolyte quality at outlet 706. If the clarity meets the standard, it can be recycled; otherwise, adjust the purification parameters. Regular shutdown maintenance: open the tank cover 500 and clean the cylinder frame 202 and coarse filter plate 204 to remove residual impurities; the fan-shaped frame 303 can be pulled out to replace the microporous filter membrane 305. Adsorption material replacement: unscrew the adsorption cylinder 600 and replace the activated carbon filter cylinder 601 and silica gel adsorption particles. Ion exchange resin maintenance: access the ion exchange cylinder 700 through the closed door 705 to check or replace the cation and anion exchange resin columns. Clean the filter screen plate 702 and filter cover 703 to prevent scale buildup.

[0029] This application includes a PLC controller, a control panel, and a power supply battery, and belongs to the prior art for equipment control and operation.

[0030] Beneficial effects: Through the coordinated operation of multiple purification units such as the coarse filter plate 204, microporous filter membrane 305, adsorption cylinder 600, and ion exchange cylinder 700, the electrolyte sequentially undergoes physical filtration, adsorption to remove organic matter, and ion exchange to remove impurity ions, achieving comprehensive purification from large suspended particles to fine ions. This multi-stage process ensures high cleanliness of the electrolyte, effectively extending the lifespan of the anodizing process and avoiding oxide film quality problems caused by incomplete purification in traditional methods. The device is equipped with a rotating rod 400 driven by a motor 404 and a scraper 401, which can automatically clean the adhering impurities on the surface of the coarse filter plate 204 to prevent clogging. This automated design reduces the frequency of manual cleaning and improves the stability of continuous operation. At the same time, the PLC controller enables full monitoring, making operation simpler and suitable for industrial production line environments, improving production efficiency. The cylinder frame 202 is slidably engaged with the convex strip 201 via the groove 203. The frame 303 is engaged with the slot 301 via the second protrusion 304, enabling quick disassembly and replacement. This modular design makes the maintenance of filter plates, filter membranes, and adsorption materials quick and reduces downtime. In addition, the closed door 705 of the ion exchange cylinder 700 facilitates access to the resin column, further enhancing the applicability and durability of the device. By circulating and purifying the electrolyte, waste liquid discharge and the consumption of fresh electrolyte are reduced, lowering operating costs and environmental burden. The activated carbon and silica gel materials in the adsorption cylinder 600 are reusable, and the ion exchange resin is regenerable, embodying the green design concept and meeting the requirements of sustainable development. The filter cylinder 100, adsorption cylinder 600, and ion exchange cylinder 700 are tightly connected by connecting pipe 103 and connecting pipe 205, occupying little space and easy to deploy in limited areas. The cover 500 is bolted to the flange 101 of the filter cylinder 100, ensuring airtightness and adapting to various industrial environments.
