Description

Technical Field

[0001] This utility model relates to the field of pickling tank technology, and in particular to a metal material pickling tank with a filtration structure. Background Technology

[0002] A pickling tank is a device used to remove oxide layers, rust, oil, and other impurities from metal surfaces using an acidic solution. It is widely used in machinery manufacturing, steel smelting, and the electronics industry. During metal processing, pickling tanks are used to clean metal surfaces to remove oxide scale, oil, and other impurities generated during processing, thereby improving the precision and performance of the metal materials. The working principle of a pickling tank is mainly based on the chemical reaction between the acidic solution and the metal surface. A pickling tank typically consists of a tank body and a heating device. The tank body is the main part of the pickling tank, used to hold the acidic solution and the metal material.

[0003] Existing pickling tanks typically place profiles in the pickling tank for surface pickling treatment. However, the oxides on the surface of the profiles have a strong adhesion and are not easy to remove. In addition, the pickling process requires a large amount of pickling solution, which can easily lead to waste of resources.

[0004] An existing patent (publication number: CN209741277U) discloses a pickling tank, which includes a tank body with a base connected to its lower part. A heating tank is located in the center of the base's interior. One end of a No. 3 pipe is connected to the center of each side of the heating tank. The other end of the No. 3 pipe is connected to the side of a pump. The pump is connected to one end of a No. 1 pipe, and the other end of the No. 1 pipe is connected to a liquid storage device. This design can thoroughly pickle profiles, improving pickling quality, and effectively reduce the amount of pickling solution used, thus saving resources.

[0005] To address the aforementioned issues, while existing patents offer solutions that can thoroughly pickle profiles, improve pickling quality, and effectively reduce the amount of pickling solution used, these solutions are inconvenient for filtering impurities in the pickling solution during pickling cycle, causing these impurities to easily re-adhere to the surface of the workpiece. Summary of the Invention

[0006] The purpose of this invention is to provide a metal pickling tank with a filtration structure, which can drive a water wheel to rotate, thereby driving a transmission rod to rotate. At this time, the rotation of the transmission rod drives the stirring blade to move, stirring the pickling liquid inside the pickling tank, ensuring the pickling effect on the workpiece, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a metal pickling tank with a filtration structure, comprising a pickling tank body, wherein two heating tubes are fixed inside the pickling tank body by screws, and a stirring mechanism for stirring the pickling solution is provided at the lower end of the interior of the pickling tank body, and a filtration mechanism for filtering the pickling solution is provided on the right side of the stirring mechanism.

[0008] The stirring mechanism includes a water inlet component, which is fixed to the lower end of the pickling tank body.

[0009] The filtration mechanism includes a connecting pipe connected to one side of the water inlet, an installation component connected to the end of the connecting pipe, an installation pipe connected to one end of the installation component, and a filter plate installed inside the installation component.

[0010] Preferably, both ends of the filter plate are fixed with locking blocks that are plugged into the mounting component, and one end of the filter plate is fixed with a movable plate that is movably connected to the mounting component.

[0011] Preferably, an impeller is installed inside the mounting tube, and a connecting rod is fixed to one end of the impeller.

[0012] Preferably, a filter screen is rotatably connected to the outer surface of the connecting rod via a bearing, and two scraping parts that are tightly fitted to the sidewall of the filter screen are fixed at the end of the connecting rod.

[0013] Preferably, a water wheel is installed inside the water inlet, and a transmission rod is fixed inside the water wheel. The transmission rod is rotatably connected to the inner wall of the water inlet via a bearing.

[0014] Preferably, two stirring blades are symmetrically fixed at the upper end of the transmission rod, and a water inlet is provided on the side wall of the water inlet component.

[0015] Preferably, a circulation pump is connected to one side of the mounting pipe, and the output end of the circulation pump is connected to a delivery pipe that is interconnected with the pickling tank.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The set stirring mechanism can drive the water wheel to rotate, which in turn drives the transmission rod to rotate. At this time, the rotation of the transmission rod drives the stirring blade to move, stirring the pickling solution inside the pickling tank, ensuring the pickling effect on the workpiece;

Detailed Implementation

[0026] 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.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 4 A metal pickling tank with a filtration structure includes a pickling tank body 1. Two heating tubes 2 are fixed inside the pickling tank body 1 by screws. A stirring mechanism for stirring the pickling solution is provided at the lower end of the pickling tank body 1. A filtration mechanism for filtering the pickling solution is provided on the right side of the stirring mechanism.

[0029] The stirring mechanism includes a water inlet 3, which is fixed at the lower end inside the pickling tank 1.

[0030] The filtration mechanism includes a connecting pipe 4, which is connected to one side of the water inlet 3. The end of the connecting pipe 4 is connected to an installation component 41. One end of the installation component 41 is connected to an installation pipe 42. A filter plate 43 is installed inside the installation component 41. Both ends of the filter plate 43 are fixed with locking blocks 44 that are inserted and connected to the installation component 41. One end of the filter plate 43 is fixed with a movable plate 49 that is movably connected to the installation component 41. An impeller 45 is installed inside the installation pipe 42. One end of the impeller 45 is fixed with a connecting rod 46. The outer surface of the connecting rod 46 is rotatably connected to a filter screen 47 through a bearing. Two scraping parts 48 that are tightly attached to the side wall of the filter screen 47 are fixed at the end of the connecting rod 46.

[0031] By adopting the above technical solution, before using the pickling tank with the filter structure, the pickling tank 1 is first placed in a suitable position. During use, the workpiece to be pickled is placed on the external fixing frame and then placed into the pickling tank 1. The heating pipe 2 heats the pickling solution, thus better pickling the workpiece. The circulating pump 5 draws out the pickling solution from the pickling tank 1. When the pickling solution passes through the filter plate 43, larger impurities in the pickling solution are filtered out. After filtration, it re-enters the installation pipe 42, where smaller impurities are filtered through the filter screen 47. The filtered pickling solution is then passed through the impeller 45... The circulating pump 5 draws out the pickling liquid and sends it back to the pickling tank 1 through the delivery pipe 6 for recycling. When the pickling liquid passes through the impeller 45, it drives the impeller 45 to rotate, which in turn drives the connecting rod 46 to rotate. At this time, the scraper 48 is driven to move synchronously. The scraper 48 is a scraper with a groove. When the scraper 48 moves, it scrapes off the impurities blocked by the side wall of the filter screen 47, so that these impurities are collected in the groove inside the scraper 48. The installation pipe 42 can be removed from the installation part 41, which facilitates the internal cleaning. Furthermore, the movable plate 49 can be manually pulled by the locking block 44 on the filter plate 43, which allows the filter plate 43 to be disassembled for easy replacement.

[0032] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, a water wheel 31 is installed inside the water inlet 3, and a transmission rod 32 is fixed inside the water wheel 31. The transmission rod 32 is rotatably connected to the inner wall of the water inlet 3 through a bearing. Two stirring blades 34 are symmetrically fixed at the upper end of the transmission rod 32. A water inlet 33 is opened on the side wall of the water inlet 3. A circulation pump 5 is connected to one side of the installation pipe 42. The output end of the circulation pump 5 is connected to a delivery pipe 6 that is connected to the pickling tank 1.

[0033] By adopting the above technical solution, when the pickling solution enters the water inlet 3 through the inlet 33, it will drive the water wheel 31 to rotate, which in turn drives the transmission rod 32 to rotate. At this time, the rotation of the transmission rod 32 drives the stirring blade 34 to move, stirring the pickling solution inside the pickling tank 1, ensuring the pickling effect on the workpiece. The pickling solution after driving the water wheel 31 to rotate will enter the mounting part 41 through the connecting pipe 4.

[0034] Working principle: The heating tube 2 heats the pickling solution, and the circulating pump 5 draws out the pickling solution from the pickling tank 1. When the pickling solution enters the water inlet 3 through the water inlet 33, it drives the water wheel 31 to rotate, which in turn drives the transmission rod 32 to rotate. At this time, the rotation of the transmission rod 32 drives the stirring blade 34 to move, stirring the pickling solution inside the pickling tank 1. The pickling solution after driving the water wheel 31 to rotate will enter the mounting part 41 through the connecting pipe 4. After filtration, it will enter the mounting pipe 42 again. Smaller impurities in the pickling solution will be filtered through the filter screen 47. The filtered pickling solution will be drawn out by the circulating pump 5 through the impeller 45 and sent back to the pickling tank 1 through the conveying pipe 6 for recycling. This allows these impurities to be collected in the groove in the scraper 48. The mounting pipe 42 can be removed from the mounting part 41, which facilitates the cleaning of the inside.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
