Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic cleaning of cold-rolled steel sheets, specifically to an experimental device for simulating electrolytic cleaning of cold-rolled steel sheets. Background Technology

[0002] Cold-rolled steel sheets are made from hot-rolled steel billets through further cold rolling. During the processing, it is necessary to remove impurities from the surface of the cold-rolled steel sheets. However, the existing processing equipment still has certain defects in use. In use, the processing technology is mostly pickling, that is, a support frame is set in the pickling tank, and the cold-rolled steel sheets are placed directly in it and pickling solution is passed through for pickling. Since multiple cold-rolled steel sheets are stacked, the contact area with the pickling solution is insufficient, which reduces the overall processing efficiency.

[0003] To overcome the above-mentioned defects, prior art 1 (Chinese patent application number 202223418365.5, application date 2022-12-20) provides a cold-rolled steel plate hydrochloric acid cleaning machine, including a cleaning tank, a tank cover, a rotating drum, and a rotating shaft. The rotating drum extends into the cleaning tank and is equipped with a connecting mechanism and connected to a first positioning fork. The first positioning fork can be adjusted laterally on the rotating drum. A motor is mounted on the right end of the cleaning tank, and the motor output shaft is connected to the rotating shaft via a coupling. A second positioning fork is fixed on the left end of the rotating shaft. The first and second positioning forks are mirror-symmetrically arranged, with plugs welded to each fork end. An agitator is fixed on the rotating shaft. A placement cage is sandwiched between the first and second positioning forks, with a cage cover. A positioning mechanism is installed inside the placement cage, which can drive the placement cage and the cold-rolled plate inside to rotate, thereby facilitating the reaction of the cold-rolled plate with the pickling solution at different positions. This allows for full contact with the pickling solution and accelerates the reaction. When the agitator rotates, it drives the hydrochloric acid solution to flow, which, together with the rotating cold-rolled plate, facilitates the washing of the cold-rolled plate by the hydrochloric acid solution.

[0004] While existing technologies can increase the contact area between the cold-rolled sheet and the treatment liquid, during operation, the rotation of the agitator and the cold-rolled sheet helps the hydrochloric acid solution flow and accelerates the reaction. However, the overall process is easily affected by the rotation speed, resulting in incomplete treatment. Furthermore, rotating the cold-rolled sheet can cause friction, reducing the overall service life. Additionally, the hydrochloric acid solution generates harmful substances when dissolving the surface of the cold-rolled sheet, requiring complex processing, which increases the cost of treatment and the environmental burden.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing experimental apparatus for simulating electrolytic cleaning of cold-rolled steel sheets. Therefore, we propose an experimental apparatus for simulating electrolytic cleaning of cold-rolled steel sheets that can effectively solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide an experimental device for simulating the electrolytic cleaning of cold-rolled plates, so as to solve the problems raised in the above background technology. Currently in the market, the rotation of the stirring paddle and the cold-rolled plate is used to help the hydrochloric acid solution flow and accelerate the reaction. The whole is easily affected by the rotation speed, resulting in incomplete treatment. And the rotation of the cold-rolled plate easily causes friction, reducing the overall service life. When the hydrochloric acid solution dissolves the surface of the cold-rolled plate, harmful substances are produced, which requires complex treatment, increasing the treatment cost and environmental burden.

[0007] To achieve the above purpose, the present utility model provides the following technical solutions: An experimental device for simulating the electrolytic cleaning of cold-rolled plates includes an experimental box provided. A cleaning tank is installed inside the experimental box. A clamping block is installed at the inner bottom of the cleaning tank. A first placement groove is opened on the clamping block, and the first placement groove is opened in a "rice" shape. A clamping member for restricting the position of the cold-rolled plate is provided on the inner wall of the cleaning tank. A heating member is installed at the bottom of the cleaning tank.

[0008] Preferably, a limiting groove is opened at the upper top of the experimental box. A first magnetic block is provided inside the limiting groove, and the first magnetic block is adapted to the second magnetic block after being powered on.

[0009] Preferably, the second magnetic block is located at the bottom of the limiting block, and the limiting block is installed at the side end of the cleaning tank.

[0010] Preferably, the limiting block is connected through the outside of the guiding rod. The guiding rod is provided inside the limiting groove, and a spring is sleeved on the outside of the guiding rod.

[0011] Preferably, a protection plate for preventing the electrolyte from splashing is provided at the upper top of the experimental box, and a slider is installed on the top of the protection plate.

[0012] Preferably, the slider is slidably connected to the outside of the sliding rod, and the sliding rod is installed inside a second placement groove opened at the side end of the experimental box.

[0013] Preferably, a first half-tube is provided at the side end of the protection plate. A limiting plate is installed on the experimental box through a limiting bolt, and a second half-tube is provided at the side end of the limiting plate.

[0014] Preferably, the first half-tube is adapted to the second half-tube, and the thread grooves on the outside of the first half-tube and the second half-tube are adapted to each other.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: For the experimental device for simulating electrolytic cleaning of cold-rolled plates, the first storage grooves arranged in a "rice" shape on the clamping blocks facilitate the cold-rolled plates to be clamped after tilting, enabling electrolytic operations on the entire surface of the cold-rolled plates, reducing the friction problems caused by rotating the cold-rolled plates for treatment, improving the overall service life, reducing the treatment cost and the burden on the environment by using electrolytic operations, ensuring a relatively uniform cleaning effect through uniform current distribution, and reducing the problem of incomplete treatment caused by using hydrochloric acid solution for treatment. The specific content is as follows:

[0016] (1) The clamping parts and the clamping blocks limit the cold-rolled plates, enabling electrolytic operations on the entire surface of the cold-rolled plates, reducing the friction problems caused by rotating the cold-rolled plates for treatment, ensuring a relatively uniform cleaning effect through uniform current distribution, reducing the treatment cost and the burden on the environment, and reducing the problem of incomplete treatment caused by using hydrochloric acid solution for treatment;

[0017] (2) By performing power-on and power-off operations on the first magnetic blocks in the limiting grooves, the first magnetic blocks cooperate with the second magnetic blocks at the bottom of the limiting blocks, facilitating the shaking of the cleaning tank. The shaking function realized through electromagnetic cooperation can make the electrolyte flow in the cleaning tank, further promoting the full contact between the cold-rolled plates and the electrolyte, and improving the uniformity and effect of electrolytic cleaning;

[0018] (3) The height of the cleaning tank is lower than the height of the cleaning tank placement groove inside the experimental box, facilitating the shaking of the cleaning tank inside the cleaning tank placement groove of the experimental box. The springs arranged on the outer side of the guiding rods make the shaking of the cleaning tank more stable, not only effectively preventing the cleaning tank from being damaged due to collisions during shaking, extending the service life of the experimental device, but also improving the processing efficiency of the cold-rolled plates;

[0019] (4) The protective plate protects the top of the cleaning tank. The setting of the protective plate effectively prevents the splashing of the electrolyte, ensuring the safety and cleanliness of the experimental environment, and avoiding potential hazards caused by the electrolyte to the experimental equipment and operators;

[0020] (5) Using joints for threaded connection not only enables the stable connection between the protective plate and the limiting plate, greatly improving the protective stability of the cleaning tank, but also enables the gas generated by electrolysis to be导出. The gas导出 function avoids potential safety hazards caused by gas accumulation during the experiment. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] 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.

[0030] Example 1: In this example, the locking block 3 and the locking member 5 limit the cold-rolled sheet, ensuring that the entire surface of the cold-rolled sheet is electrolyzed, thus reducing friction caused by rotating the cold-rolled sheet during processing. Figures 1-5The described technical solution includes an experimental box 1 provided. Inside the experimental box 1, a cleaning tank 2 is installed. At the inner bottom of the cleaning tank 2, a clamping block 3 is installed. A first storage groove 4 is opened on the clamping block 3, and the first storage groove 4 is opened in a "rice" shape. A clamping member 5 for restricting the position of the cold-rolled sheet is provided on the inner wall of the cleaning tank 2. A heating member 6 is installed at the bottom of the cleaning tank 2. The cold-rolled sheet to be electrolyzed is clamped into the inside of the clamping member 5, which facilitates the support of the cold-rolled sheet through the first storage groove 4 of the clamping block 3, greatly improving the support stability of the cold-rolled sheet and reducing the problem of unstable reaction caused by the displacement of the cold-rolled sheet during electrolysis. Moreover, the first storage groove 4 opened in a "rice" shape on the clamping block 3 facilitates the clamping of the cold-rolled sheet after tilting, enabling the entire surface of the cold-rolled sheet to be subjected to electrolysis operations. This not only reduces the problem that the part of the cold-rolled sheet clamped into the inside of the clamping member 5 has less contact with the electrolyte, improving the accuracy of the overall experimental data, but also reduces the friction problem caused by rotating the cold-rolled sheet for treatment, increasing the overall service life. Turning on the heating member 6 inside the experimental box 1 facilitates the heating operation of the electrolyte inside the cleaning tank 2, accelerating the electrolysis reaction, shortening the experimental period, thereby improving the overall electrolysis efficiency, reducing the treatment cost and the burden on the environment. Through the uniform distribution of current, a relatively uniform cleaning effect can be ensured, reducing the problem of incomplete treatment caused by using hydrochloric acid solution for treatment.

[0031] Embodiment 2: In this embodiment, the jitter function achieved through electromagnetic cooperation can make the electrolyte flow inside the cleaning tank 2, further promoting the full contact between the cold-rolled sheet and the electrolyte, and improving the uniformity and effect of electrolytic cleaning. Specifically, as Figures 4-7 shown, a limiting groove 7 is opened at the upper top of the experimental box 1. A first magnetic block 8 is arranged inside the limiting groove 7. After the first magnetic block 8 is powered on, it is adapted to the second magnetic block 12. The second magnetic block 12 is located at the bottom of the limiting block 11. The limiting block 11 is installed at the side end of the cleaning tank 2. The limiting block 11 is connected through the outside of the guiding rod 9. The guiding rod 9 is arranged inside the limiting groove 7. A spring 10 is sleeved on the outside of the guiding rod 9. The provided cleaning tank 2 can be conveniently clamped onto the guiding rod 9 of the limiting groove 7 through the limiting block 11 at the side end. Therefore, the first magnetic block 8 inside the limiting groove 7 can be powered on and off, enabling the first magnetic block 8 to cooperate with the second magnetic block 12 at the bottom of the limiting block 11, facilitating the jitter of the cleaning tank 2. The jitter function achieved through electromagnetic cooperation can make the electrolyte flow inside the cleaning tank 2, further promoting the full contact between the cold-rolled sheet and the electrolyte, and improving the uniformity and effect of electrolytic cleaning. The height of the cleaning tank 2 is lower than the height of the groove for placing the cleaning tank 2 inside the experimental box 1, facilitating the jitter of the cleaning tank 2 inside the groove for placing the cleaning tank 2 in the experimental box 1. Moreover, the spring 10 arranged on the outside of the guiding rod 9 makes the jitter of the cleaning tank 2 more stable. This not only can effectively prevent the cleaning tank 2 from being damaged due to collision during jitter, extending the service life of the experimental device, but also improves the processing efficiency of the cold-rolled sheet.

[0032] Example 3: In this example, the protective plate 13 effectively prevents electrolyte splashing, ensuring the safety and cleanliness of the experimental environment and avoiding potential hazards to experimental equipment and operators from the electrolyte. Specifically, as follows... Figures 3-7 As shown, the top of the experimental chamber 1 is equipped with a protective plate 13 to prevent electrolyte splashing. A slider 14 is installed on the top of the protective plate 13, and the slider 14 is slidably connected to the outside of a slide rod 15. The slide rod 15 is installed inside the second storage slot 16 opened on the side of the experimental chamber 1. A first half-tube 17 is provided on the side of the protective plate 13. A limit plate 19 is installed on the experimental chamber 1 by a limit bolt 20. A second half-tube 18 is provided on the side of the limit plate 19. The first half-tube 17 and the second half-tube 18 are adapted to each other, and the threaded groove on the outside of the first half-tube 17 and the second half-tube 18 are adapted to each other. When the cold-rolled plate is processed, the protective plate 13 is moved on the slide rod 15 inside the second storage slot 16 opened on the side of the experimental chamber 1 by the slider 14 at the bottom, so that the protective plate 13 protects the top of the cleaning tank 2. The setting of the protective plate 13 effectively prevents electrolyte splashing and ensures the safety and cleanliness of the experimental environment. The cleaning process is clean, avoiding potential hazards to experimental equipment and operators from the electrolyte. At this time, the first half-tube 17 on the protective plate 13 moves to the side of the second half-tube 18 on the limiting plate 19. Since the outer thread grooves of the first half-tube 17 and the second half-tube 18 are compatible, it is convenient to use a connector for threaded connection. This not only makes the protective plate 13 and the limiting plate 19 stably connected, greatly improving the protective stability of the cleaning chamber 2, but also allows the gas generated by electrolysis to be discharged. The gas discharge function avoids the safety hazards that may be caused by gas accumulation during the experiment. The limiting plate 19 is installed on the experimental box 1 by the limiting bolt 20. The limiting bolt 20 allows for quick operation when the experimental device needs to replace parts, improving the maintenance efficiency of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention 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 invention should be included within the protection scope of the present invention.
