Description

TECHNICAL FIELD

[0001] The utility model relates to metal surface treatment technical field, especially a pickling device for metal surface treatment. BACKGROUND

[0002] In the field of metal processing and manufacturing, metal surface treatment is a key link to guarantee product quality and performance. Pickling, as a common metal surface treatment method, uses acid solution to chemically react with the oxide scale and rust on the metal surface, dissolving and removing them to achieve the purpose of cleaning the metal surface.

[0003] The strong acid in the pickling solution rapidly reacts with the oxide scale and rust layer on the metal surface, dissolving them into water-soluble salts. Meanwhile, the hydrogen ions in the acid solution react with the metal to generate hydrogen gas bubbles, which help to peel off the oxide scale and rust layer, greatly improving the rust removal efficiency.

[0004] During pickling, the workpiece is often in a relatively static state, and the contact between the acid solution and the workpiece surface is not sufficient and uniform, resulting in poor pickling effect and difficulty in completely removing impurities on the metal workpiece surface, which affects product quality.

[0005] Therefore, it is necessary to invent a pickling device for metal surface treatment to solve the above problems. SUMMARY

[0006] The utility model aims at providing a pickling device for metal surface treatment to solve the problem of insufficient and uniform contact between the acid solution and the workpiece surface, leading to poor pickling effect and difficulty in completely removing impurities on the metal workpiece surface, which affects product quality.

[0007] To achieve the above purpose, the utility model provides the following technical scheme: a pickling device for metal surface treatment, comprising:

[0044] 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.

[0045] This utility model provides, for example Figures 1-5 A pickling apparatus for metal surface treatment is shown, comprising:

[0046] Pickling tank 100;

[0047] A dividing plate 200 is installed inside the pickling tank 100, dividing the pickling tank 100 into two independent cavities 110. These two cavities 110 can be flexibly used to store different types of acid solutions, such as oxidizing acid solutions and non-oxidizing acid solutions, and can also be used for pickling operations at different stages, such as pre-pickling and deep pickling in separate cavities.

[0048] The 300 hanging basket is designed with a grid structure and the inner surface is bonded with corrosion-resistant perfluoroether rubber, polytetrafluoroethylene or fluororubber, which does not prevent the acid from fully contacting all surfaces of the workpiece to achieve a comprehensive pickling effect.

[0049] The drive assembly 400, installed on the pickling tank 100, drives the basket 300 to slide back and forth above the two cavities 110. It can precisely drive the basket 300 to slide back and forth smoothly along the preset track to the top of the two cavities 110, thereby quickly and accurately realizing convenient switching between different acids or different pickling stages.

[0050] The telescopic rod 500 is installed on the drive assembly 400, which drives the basket 300 to descend into the cavity 110 or rise out of the cavity 110. The basket 300 slowly descends into the cavity 110, so that the metal workpiece is completely immersed in the acid solution for efficient pickling. After pickling is completed, it can rise quickly to detach the basket 300 from the cavity 110, so as to carry out subsequent operations such as workpiece transfer and draining.

[0051] The blower assembly 600 is installed on the dividing plate 200 and pushes the basket 300 to swing in stages. During the pickling process, the blower assembly 600 is started in stages at preset time intervals. The strong airflow generated by the high-pressure blower blows the basket 300 precisely through the adjustable nozzle, pushing the metal workpiece in the basket 300 to swing periodically during the pickling process, so that all parts of the workpiece can fully and evenly contact the acid solution, thereby achieving a more uniform and better pickling effect.

[0052] The working principle of this embodiment is as follows:

[0053] The metal is placed inside the basket 300 and moved above the corresponding cavity 110 according to the pickling procedure. Then, the telescopic rod 500 is activated, causing the basket 300 to descend into the cavity 110 and immerse it in the pickling solution. The blower assembly 600 is then activated, intermittently applying airflow to the basket 300, causing it to swing the metal. After pickling is complete, the telescopic rod 500 is activated again, causing the basket 300 to rise. The drive assembly 400 is then activated, moving the basket 300 above another cavity 110. The above steps are repeated.

[0054] In this process, the 300-stage swinging of the basket in stages causes the workpiece to sway in the acid solution, which effectively improves the uniformity of pickling, ensures that impurities on the surface of the metal workpiece can be fully removed, and improves the quality of pickling. At the same time, the swinging process also helps to remove residual acid from the surface of the workpiece, providing a good foundation for subsequent processing steps.

[0055] The combination of the drive assembly 400 and the telescopic rod 500 enables the automatic movement of the basket 300 between different pickling zones and the automatic lifting and lowering of the workpiece, reducing manual operation, lowering labor intensity, and improving production efficiency.

[0056] In some embodiments of this utility model, reference is made to Figure 2 and Figure 4 As shown, mounting plates 310 are fixedly installed at both ends of the suspended platform 300. A symmetrical U-shaped frame 320 is fixedly connected to the mounting plates 310 above the suspended platform 300. A hinge frame 330 is fixedly installed on the top of the U-shaped frame 320. This not only facilitates a precise and secure connection between the suspended platform 300 and the telescopic rod 500, but also facilitates the connection and cooperation between the suspended platform 300, the telescopic rod 500, and other components. Moreover, when working in conjunction with other components, it can achieve efficient and stable cooperation, ensuring the smooth operation of the entire pickling device.

[0057] In some embodiments of this utility model, reference is made to Figure 5 As shown, the bottom of the telescopic rod 500 is fixed with a support plate 510 that is hinged to the hinge frame 330 via a pin, and a coil spring 520 is fixedly installed at the connection between the support plate 510 and the hinge frame 330.

[0058] When the basket 300 is swinging, the coil spring 520 can provide auxiliary torsional force to the basket 300 by its own elastic deformation, making the basket 300 more flexible and smooth during the swing. When the basket 300 completes the swinging action, the elastic potential energy stored in the coil spring 520 is released instantly, driving the basket 300 to quickly and automatically reset, ensuring that the position of the basket 300 is accurate and uniform during each pickling.

[0059] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 As shown, the blower assembly 600 includes:

[0060] The air guide frame 610 is detachably and fixedly installed on the top of the partition plate 200, which allows for convenient operation of the air guide frame 610 during device maintenance, repair or replacement of parts.

[0061] The air duct 620 is used to provide airflow to the air guide frame 610. The air duct 620 has a standard interface and can be smoothly connected to an external air source. It can flexibly adjust the input airflow pressure and flow rate according to actual needs to meet the requirements of the blower assembly 600 under different working conditions.

[0062] There are two sets of air outlets 630, which are respectively installed on both sides of the air guide frame 610. When the airflow flows from the air guide duct 620 through the air guide frame 610 to the air outlets 630, the two sets of air outlets 630 can blow air onto the basket 300 from different directions. The airflow impact force can be effectively used to make the basket 300 swing, thereby achieving more comprehensive and efficient drying or cleaning of metal objects inside the basket 300.

[0063] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 As shown, the drive component 400 includes:

[0064] Two sets of support rods 410 are provided and are fixedly installed at both ends of the top of the pickling tank 100, laying the foundation for the subsequent construction of the device structure;

[0065] The frame plate 420 is fixedly installed on the top of the support rod 410 to ensure that the components can be assembled in an orderly manner and operate in coordination.

[0066] There are two guide rods 430, which are fixedly installed between the two frame plates 420.

[0067] In some embodiments of this utility model, reference is made to Figure 2 and Figure 4 As shown, the drive component 400 also includes:

[0068] The threaded rod 440 rotatably passes through the two brackets 420. One end of the threaded rod 440 is connected to an external drive source, such as a motor. When the motor runs and drives the threaded rod 440 to rotate, it can provide power for the subsequent movement of the sliding plate 450, thereby driving the sliding plate 450 to move.

[0069] The sliding plate 450 slides laterally along the two guide rods 430. The guide rods 430 provide precise guidance for the movement of the sliding plate 450, ensuring that it does not deviate during the movement.

[0070] The threaded sleeve 460 is fixed at the center of the sliding plate 450 and drives the sliding plate 450 to move under the drive of the threaded rod 440. When the threaded rod 440 rotates, the threaded sleeve 460 drives the sliding plate 450 to move laterally along the guide rod 430 under the action of threaded transmission. In this way, the position of the basket 300 connected to the sliding plate 450 can be controlled, which meets the strict requirements for the position adjustment of the basket 300 in the pickling process of metal surface treatment.

[0071] In some embodiments of this utility model, reference is made to Figure 4 As shown, the telescopic rod 500 is detachably and fixedly connected to a receiving sleeve 530 installed on the sliding plate 450. When the telescopic rod 500 is damaged and needs to be replaced, the replacement process can be completed efficiently, effectively improving the efficiency of equipment maintenance and replacement and reducing equipment downtime.

[0072] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 As shown, two drain pipes 120 are fixedly installed on the outside of the pickling tank 100, which are respectively connected to the two cavities 110. After the pickling process is completed, the drain pipes 120 can quickly and efficiently discharge the waste liquid after pickling, preparing for the next round of pickling operation, and also greatly facilitating the subsequent centralized collection of waste liquid.

[0073] The working method of this utility model:

[0074] Place the metal workpiece to be pickled inside the basket 300;

[0075] By rotating the threaded rod 440, the sliding plate 450 drives the telescopic rod 500 and the basket 300 to move above one of the cavities 110;

[0076] The telescopic boom 500 is activated, causing the basket 300 to descend into the acid solution within the cavity 110 for pickling. At this time, the blower assembly 600 operates, providing airflow to the air guide frame 610 through the air duct 620. The airflow exits from the blowers 630 on both sides, pushing the basket 300 to swing, causing the metal workpiece to continuously change angles in the acid solution, ensuring uniform pickling. During the swinging process, the coil spring 520 assists in the swinging and resetting.

[0077] After pickling is completed, the telescopic rod 500 drives the basket 300 to rise and detach from the acid solution;

[0078] Rotate the threaded rod 440 again to move the basket 300 above another cavity 110 and repeat the above pickling process. Pickling with different acids or different stages of pickling can be performed as needed.

[0079] After pickling, the waste liquid in cavity 110 is discharged through drain pipe 120 for subsequent treatment.

[0080] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0081] 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.
