[0002] Anodizing tanks are core equipment in the field of metal surface treatment. They are widely used for surface oxidation treatment of workpieces such as aluminum alloys and magnesium alloys. Through electrolytic reaction, a dense oxide film is formed on the surface of the workpiece to improve its wear resistance, corrosion resistance and decorative properties.

[0003] In the production of products such as laptop casings and automotive parts, the stability of the anodizing tank directly affects the uniformity of the oxide film and the quality of the workpiece. Therefore, protective structures are needed to ensure the purity of the electrolyte, the sealing of the equipment, and the safety of operation.

[0004] However, traditional anodizing tanks have some shortcomings in long-term use. During the oxidation process, metal shavings, oil stains and other impurities will fall off. These impurities are easily attached to the surface of the workpiece after mixing with the electrolyte, resulting in defects such as pinholes and spots on the oxide film. Traditional tanks lack real-time filtration and impurity cleaning functions, requiring frequent shutdowns for cleaning, which affects production efficiency.

[0005] To address this issue, an anodizing tank with a protective structure is proposed. Utility Model Content

[0032] 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.

[0033] Reference Figure 1 - Figure 2 This utility model provides an embodiment of an anodizing tank with a protective structure, including a tank body 1 for storing electrolyte. A mounting bracket 2 is fixedly connected to the inner wall of the top of the tank body 1. Multiple sets of mounting brackets 2 are provided to facilitate the fixing of workpieces undergoing anodizing. A base plate 6 is fixedly connected to the inner wall of the bottom of the tank body 1. The tank body 1 and the base plate 6 are installed by welding. Support feet 7 are fixedly connected to the four corners of the lower surface of the base plate 6, supporting the entire device. A protective component 3 is provided at the left end of the tank body 1 to achieve a protective effect. The protective component 3 can filter the electrolyte in the tank body 1, ensuring the stability of its anodizing effect on the workpiece. A sealing component 4 is provided inside the tank body 1 to ensure a seal and prevent electrolyte leakage.

[0034] Reference Figure 1 , Figure 2 , Figure 4 The protective component 3 includes a suction pump 31, which is existing technology and can be implemented by those skilled in the art. As it is existing technology, it will not be described in detail in this case. The suction pump 31 is set on the left surface of the tank 1. A connecting pipe 32 is connected through and fixedly connected to the left surface of the tank 1. A slot 36 is opened on the upper surface of the tank 1. A filter plate 34 is inserted into the inner wall of the slot 36. The slot 36 and the filter plate 34 fit together and their contact surfaces are in contact. A pull ring 35 is fixedly connected to the upper surface of the filter plate 34. A finger can pass through the pull ring 35 for easy pulling. A positioning component 5 is set at the top of the filter plate 34. A baffle 33 is fixedly connected to the inner wall of the tank 1 to prevent the filtered electrolyte from impacting the surface of the anodized workpiece, thereby ensuring the stability of the anodizing effect.

[0035] Reference Figure 1 , Figure 2 , Figure 4 The suction pump 31 is located at the bottom of the connecting pipe 32. The suction pump 31 can draw the electrolyte into the connecting pipe 32. The baffle 33 is located on the right side of the filter plate 34. The upper surface of the bottom plate 6 is set to be inclined from left to right to facilitate the flow of the electrolyte under its own gravity. The inner surface of the filter plate 34 is provided with multiple sets of filter holes in an array to facilitate the flow of electrolyte. However, impurities will be blocked by the filter holes and deposited at the bottom of the filter plate 34 for subsequent centralized treatment.

[0036] Reference Figure 1 , Figure 2 , Figure 4 The positioning component 5 includes a connecting plate 51, and the inner wall of the groove 1 is elastically connected to a locking block 53 via an elastic element 54. A buckle 52 for easy pulling is fixedly connected to the right surface of the connecting plate 51.

[0037] Reference Figure 1 , Figure 2 , Figure 4 Two sets of locking blocks 53 and elastic elements 54 are provided. The two sets of locking blocks 53 and elastic elements 54 are symmetrically distributed about the center line of the groove 1. The upper surfaces of the two sets of locking blocks 53 are fixedly connected to the front and rear ends of the lower surface of the connecting plate 51, respectively. The connecting plate 51 and the two sets of locking blocks 53 will move synchronously. The top of the locking block 53 penetrates the upper surface of the groove 1. The locking block 53 is slidably connected to the inner wall of the groove 1. The locking block 53 moves laterally. The left half of the locking block 53 is located inside the slot 36 and can block the filter plate 34. The left half of the upper surface of the locking block 53 is set as an arc surface. When the arc surface is squeezed, the locking block 53 will move to the right and retract into the groove 1.

[0038] Reference Figure 1 - Figure 3The sealing component 4 includes a liner 41, which is fixedly connected to the upper surface of the base plate 6. A partition 42 is fixedly connected to the outer wall of the liner 41. The liner 41 is made of fluororubber and can play a sealing role. The partition 42 is fixedly connected to the inner wall of the tank 1. The partition 42 and the tank 1 are welded together. During use, gaps are easily generated due to the corrosion of the electrolyte.

[0039] Working principle: During the anodizing process of the workpiece, impurities will fall off the surface of the workpiece. These impurities will affect the purity of the electrolyte, which in turn will affect the quality of the subsequent anodizing of the workpiece. Therefore, it is necessary to filter the impurities to protect the oxidation quality of the subsequent workpiece.

[0040] During filtration, the suction pump 31 is started, and the electrolyte will flow to the left along the inclined surface of the sealing component 4. The suction pump 31 will draw the electrolyte in the tank 1, and the electrolyte will flow out through the connecting pipe 32 and out from the other end of the connecting pipe 32. The electrolyte will be filtered through the filter plate 34, and the electrolyte that passes through the filter plate 34 will enter the tank 1 and will be blocked by the baffle 33, which can prevent direct impact with the workpiece.

[0041] The blocked impurities will settle at the bottom of the filter plate 34. When cleaning is required, move the buckle 52 to the right to move the connecting plate 51 and the locking block 53 to the right to release the obstruction of the filter plate 34. Then pull the pull ring 35 upward to pull out the filter plate 34. Then clean the impurities. After cleaning, insert the filter plate 34 into the slot 36. During the insertion process, the filter plate 34 will press the arc surface of the locking block 53, which will cause the locking block 53 to move to the right to release the obstruction. The locking block 53 will also press the elastic element 54 to generate a reaction force. When the filter plate 34 is inserted into the slot 36, the elasticity of the elastic element 54 will push the locking block 53 out and lock it on the upper part of the filter plate 34 to limit the filter plate 34 and ensure its stability.

[0042] During prolonged use, the connection point between the partition 42 and the tank 1 will be corroded by the electrolyte, creating gaps. When the electrolyte comes into contact with the liner 41, it will be blocked, maintaining a seal.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
