Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrolyte circulation technology, specifically to a circulating filtration device for anodizing electrolyte in die-cast aluminum alloy parts. Background Technology
[0002] Die-cast aluminum alloy parts are alloys with aluminum as the base and a certain amount of other alloying elements added. They are one of the light metal materials. In addition to the general properties of aluminum, aluminum alloys also have some specific alloy properties due to the different types and amounts of alloying elements added. The density of aluminum alloys is 2.63 to 2.85 g / cm3, with high strength (σb is 110 to 650 MPa), specific strength close to that of high alloy steel, specific stiffness exceeding that of steel, good casting performance and plastic processing performance, good electrical and thermal conductivity, good corrosion resistance and weldability. They can be used as structural materials and have wide applications in aerospace, aviation, transportation, construction, electromechanical, light chemical and daily consumer goods.
[0003] Before use, die-cast aluminum alloy parts are often electrolyzed to meet their corrosion resistance requirements, which forms a dense alumina protective film on the surface of the die-cast aluminum alloy parts. This ensures that the aluminum alloy inside the alumina protective film will not be corroded during subsequent use. However, in the actual electrolysis process, the electrolyte contains a lot of impurities due to long-term use, which affects the subsequent electrolysis of the aluminum alloy and cannot meet the actual use requirements.

[0027] Example
[0028] The anodizing electrolyte circulation filtration device for die-cast aluminum alloy parts provided in this embodiment, such as... Figures 1-5 As shown, the device includes a base 1, an electroplating tank 3 is provided on the top of the base 1, and a circulating filter mechanism 6 is provided on the top of the base 1 and on the right side of the electroplating tank 3. The base 1 is used to install the electroplating tank 3 and the circulating filter mechanism 6. The electroplating tank 3 is used to electroplat aluminum alloy parts, and the circulating filter mechanism 6 is used to filter the electroplating solution inside the electroplating tank 3 to remove impurities, thereby increasing the cleanliness of the electroplating solution and facilitating subsequent electroplating.
[0029] The circulating filtration mechanism 6 includes a groove 601 inside the base 1 and a filter box 602 inside the groove 601. A partition 611 is fixedly installed inside the filter box 602. A filter element 612 is threadedly connected to one side of the partition 611. An mounting plate 603 is fixedly installed on the top of the filter box 602 by bolts. A circulating pump 604 is fixedly installed on the top of the mounting plate 603. The filter element 612 is used to filter the electroplating solution. The groove 601 is used to extend the filter box 602 into the interior of the base 1, so that the filter box 602 can create a height difference with the electroplating tank 3 to facilitate the subsequent discharge of the electroplating solution. The partition 611 is used to divide the inner cavity of the filter box 602 into two areas for containing unfiltered electroplating solution and filtered electroplating solution. The circulating pump 604 is used to send the filtered electroplating solution into the interior of the electroplating tank 3 for circulation.
[0030] The input end of the circulation pump 604 is connected to a conduit 610, and the end of the conduit 610 extends into the interior of the filter box 602. The conduit 610 is used to send the filtered electroplating solution into the interior of the circulation pump 604 so that the electroplating solution can be returned to the interior of the electroplating tank 3 for subsequent electroplating.
[0031] The output end of the circulation pump 604 is connected to a water supply pipe 605, and the end of the water supply pipe 605 extends into the interior of the electroplating tank 3. The water supply pipe 605 is used to send the circulation pump 604 into the interior of the electroplating tank 3 for subsequent circulation.
[0032] The end of the electroplating tank 3 is connected to a horizontal pipe 608, and one side of the horizontal pipe 608 is connected to a uniformly distributed nozzle 609. The horizontal pipe 608 and the nozzle 609 are used to pressurize the electroplating solution entering the electroplating tank 3 to facilitate the flow of the internal electroplating solution and facilitate the subsequent electroplating of aluminum alloy.
[0033] A return water pipe 607 is connected to the left side of the electroplating tank 3. The end of the return water pipe 607 extends into the interior of the filter box 602. A valve 606 is fixedly installed inside the return water pipe 607. The return water pipe 607 is used to backflow the electroplating solution inside the electroplating tank 3 into the interior of the filter box 602 for subsequent filtration.
[0034] Limiting frames 5 are fixedly installed on both sides of the top of the electroplating tank 3. A placement rod 4 is placed inside the limiting frame 5. The limiting frame 5 is used to limit the placement rod 4, and the placement rod 4 is used to suspend the aluminum alloy parts to be electroplated, so as to facilitate subsequent electroplating.
[0035] Four support rods 2 are fixedly installed on the top of the base 1. The top of the support rods 2 is fixedly connected to the bottom of the electroplating tank 3. The support rods 2 are used to install the electroplating tank 3 and lift the electroplating tank 3, so that there is a height difference between the electroplating tank 3 and the filter box 602, which facilitates the subsequent flow of the electroplating liquid to be filtered into the filter box 602 for filtration.
[0036] In use, the electroplating solution is added to the electroplating tank 3. The aluminum alloy parts to be electroplated are suspended below the placement rod 4, and the placement rod 4 is placed inside the limiting frame 5 for electroplating. After a period of use, when the electroplating solution needs to be filtered, the valve 606 is opened. The electroplating solution inside the electroplating tank 3 flows into the filter box 602 through the return water pipe 607. Under the obstruction of the partition 611, the electroplating solution flows through the filter element 612 to the filter box 602 on the other side of the partition 611. At this time, the filtered electroplating solution is backflowed into the electroplating tank 3 through the conduit 610, water supply pipe 605, horizontal pipe 608 and nozzle 609 by the opening of the circulation pump 604 for recycling. During continuous electroplating, the valve 606 can be slightly opened to allow the electroplating solution to flow into the filter box 602 in a metered manner for simultaneous electroplating and filtration. After use, the mounting plate 603 is removed and the filter element 612 is removed and replaced for maintenance.
[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
