Description

Technical Field

[0001] This utility model relates to the field of pickling tank technology, specifically a high-efficiency pickling tank. Background Technology

[0002] A pickling tank is a container for holding acidic solutions, commonly used in industrial production for pickling metal materials. Its basic principle is to utilize acids such as hydrochloric acid, sulfuric acid, and nitric acid to chemically react with oxides, rust, oil, and other impurities on the metal surface, dissolving and removing these unwanted substances. This achieves the purpose of cleaning the metal surface, improving its quality, and preparing it for subsequent processing such as electroplating and coating. It is generally made of acid-resistant materials, commonly fiberglass, plastics such as PP and PVC, or acid-resistant bricks with anti-corrosion coatings. The tank shape is mostly rectangular or cylindrical, and its size is designed and customized according to the production scale and the dimensions of the workpieces to be treated, ensuring sufficient space to accommodate the acid and the metal objects being processed.

[0003] Patent publication number "CN222861651U" discloses "an efficient pickling tank, comprising a pickling tank body, a top plate installed at the top of the pickling tank body, a fixing sleeve installed at the bottom of the top plate, a sliding rod slidably connected inside the fixing sleeve, a pull-out plate installed at the bottom of the sliding rod, and a water spraying mechanism installed at the bottom of the top plate." In this efficient pickling tank, after the parts are pickled, pressing the pressing block inward causes the elastic spring to store force, simultaneously releasing the sliding rod from its limit. Then, pulling the push-pull rod pulls the pull-out plate out of the pickling tank body. When the plate is pulled to the pop-out position, the elastic spring causes the pressing block to pop out quickly, fixing the pull-out plate. At this point, the water spraying mechanism washes off any residual acid on the surface of the parts. This secondary rinsing can more thoroughly remove residual acid from the surface of the parts, thereby effectively improving the efficiency and quality of pickling.

[0004] In the aforementioned patent, the existing pickling tank does not have a good filtration function, and the impurities inside can easily affect the pickling effect, thus affecting the pickling efficiency. In addition, it does not have a good limiting function, and the metal plates are prone to tipping over during the pickling process, which can easily affect the pickling effect.

[0005] Therefore, this utility model provides an efficient pickling tank to solve the above problems. Utility Model Content

[0020] Beneficial effects

[0021] This invention provides a high-efficiency pickling tank. Compared with the prior art, it has the following advantages:

[0022] 1. This high-efficiency pickling tank, through its set filter components, can filter out the debris inside in a timely manner. Timely filtration of debris prevents it from remaining in the acid solution for a long time, thus preventing it from repeatedly scraping the surface of the metal sheet with the flow of acid. This reduces damage to the original smooth surface of the metal sheet, helps maintain the flatness and appearance quality of the metal sheet, and ensures that subsequent processing and use are not affected, effectively guaranteeing work efficiency.

[0023] 2. This high-efficiency pickling tank, through its set limiting components, can effectively limit the position of metal plates, resulting in better pickling effects. The limiting components can precisely fix the position of the metal plates, preventing displacement or shaking of the metal plates due to acid agitation or other external forces such as collisions and squeezing between multiple plates during the pickling process. This ensures that all parts of the metal plates can fully and evenly contact the acid, allowing the acid to comprehensively act on the rust, oxides, and other impurities on the surface of the metal plates, achieving a thorough pickling and rust removal effect.

A water pump 46 is fixedly installed on the top of the filter box 41, and a connecting pipe 47 is fixedly connected to the input end of the water pump 46. The output end of 46 is fixedly connected to a connecting pipe 48. The filter assembly 4 also includes a positioning block 44 and a positioning frame 45. The positioning block 44 is fixedly installed on both sides of the filter frame 42, and the positioning frame 45 is fixedly installed on the top of the filter box 41. The positioning block 44 and the positioning frame 45 are interlocked. The filter assembly 4 also includes an inlet pipe 49. The inlet pipe 49 is fixedly connected to one side of the pickling tank body 1. A drain pipe 5 is fixedly connected to one side of the pickling tank body 1. The drain pipe 5 is located above the filter screen 43. A solenoid valve 6 is provided on the side wall of the drain pipe 5. The solenoid valve 6 is connected to the drain pipe 5 by bolts.

[0033] In this embodiment, the solenoid valve 6 is then opened to discharge the pickling liquid inside the pickling tank body 1 into the filter screen 43 through the drain pipe 5. After the filter screen 43 filters the pickling liquid, it enters the filter box 41. Then, the water pump 46 is started to extract the pickling liquid inside the filter box 41 through the first connecting pipe 47. Then, the second connecting pipe 48 discharges the pickling liquid back into the pickling tank body 1, making the discharge more convenient.

[0034] Reference Figures 1 to 4 In one aspect of this embodiment, the pickling assembly 2 includes a support frame 21 and a cylinder 22. The support frame 21 is fixedly connected to the top of the pickling tank body 1, and the cylinder 22 is fixedly installed on the top of the support frame 21. The output end of the cylinder 22 is fixedly connected to a lifting frame 23. A filter groove 24 is provided on the inner bottom wall of the lifting frame 23.

[0035] In this embodiment, firstly, pulling the handle 33 can drive the rotating shaft 31 to rotate at the top of the lifting frame 23 via the torsion spring through the baffle 32. Then, the metal plate is placed inside the lifting frame 23. After releasing the handle 33, the torsion spring can reset the rotating shaft 31, so that the baffle 32 can limit the torsion spring, making the metal plate more stable. Then, opening the cylinder 22 can drive the lifting frame 23 into the interior of the pickling tank body 1 to achieve the pickling effect.

[0036] Working principle: First, pulling handle 33 can drive the rotating shaft 31 to rotate at the top of the lifting frame 23 via the torsion spring through the baffle 32. Then, the metal plate is placed inside the lifting frame 23. After releasing handle 33, the torsion spring can reset the rotating shaft 31, so that the baffle 32 can limit the torsion spring, making the metal plate more stable. Then, opening cylinder 22 can drive the lifting frame 23 into the interior of the pickling tank body 1 to achieve the pickling effect.

[0037] Afterwards, opening the solenoid valve 6 allows the pickling liquid inside the pickling tank body 1 to be discharged into the filter screen 43 via the drain pipe 5. The filter screen 43 then filters the pickling liquid, which then enters the filter box 41. Afterwards, starting the water pump 46 allows the pickling liquid inside the filter box 41 to be extracted via the connecting pipe 1 47. Then, the connecting pipe 2 48 discharges the pickling liquid back into the pickling tank body 1, making the discharge process more convenient.
