Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot acid washing equipment, and in particular to a frame for reducing acid mist leakage. Background Technology
[0002] During hot rolling, forging, or heat treatment, steel balls develop oxide scale (such as Fe3O4, Fe2O3, etc.) and residual oil, weld spots, and other impurities on their surface. Hot pickling dissolves and peels off these surface defects through a chemical reaction between acid (such as sulfuric acid or hydrochloric acid) and the oxides, exposing a clean metal substrate. Furthermore, the surface roughness of the steel ball is significantly reduced after pickling (Ra can reach 0.8–1.6 μm), providing a uniform and smooth substrate for subsequent polishing, electroplating, or coating processes, and enhancing the adhesion of the plating or coating. Additionally, damage to the passivation film caused during processing (such as a chromium-depleted layer) reduces the steel ball's corrosion resistance. After pickling, a dense passivation film reforms on the metal surface (especially in chromium-containing stainless steel), significantly improving its oxidation resistance and environmental corrosion resistance. Therefore, hot pickling is an essential step in the steel ball processing technology.
[0003] Existing hot pickling equipment typically only sets up the treatment tank inside a closed frame. During the process, acid mist fills the entire frame, causing corrosion to the inside of the frame. In addition, the frame needs to be opened during loading and unloading, which leads to a large amount of acid mist leakage, which in turn causes corrosion to the equipment in the workshop. Utility Model Content
[0004] To address the shortcomings of the existing technology, the main objective of this utility model is to overcome these deficiencies and disclose a device frame for reducing acid mist leakage. The frame includes a frame body, within which a loading station, a treatment tank, and a unloading station are sequentially arranged. No doors are provided at the loading and unloading stations. A partition is also provided within the frame body, with a transition groove on the partition. A connection hole is provided on the frame body, which connects to an acid mist collection and treatment device.
[0005] Furthermore, a rubber sheet is attached to the transition groove.
[0006] Furthermore, the treatment tank includes a hot acid washing tank, a neutralization tank, and a cleaning tank arranged in sequence.
[0007] Furthermore, it also includes a partition component, which is disposed between the loading station, the unloading station and the processing pool, and uses the partition component to separate the loading area, the unloading area and the processing area.
[0008] Furthermore, the partition assembly includes a rotating shaft, a partition plate, and a servo motor. The rotating shaft is mounted on the frame body, and the partition plate is fixed on the rotating shaft. The servo motor drives the rotating shaft to rotate, thereby causing the partition plate to rotate.
[0009] Furthermore, the partition plate is fixed to the rotating shaft by screws.
[0010] Furthermore, rubber washers are provided between the partition plate and the rotating shaft, and between the screw and the partition plate.
[0011] The beneficial effects achieved by this utility model are:
[0012] This invention ensures that the acid mist inside the frame is kept at a low concentration and the internal pressure is lower than the external pressure by setting connection holes on the frame and connecting external collection and treatment equipment, thereby reducing acid mist leakage when the hopper door is opened. A partition component is installed to separate the processing area from the loading and unloading area, and its opening is covered when the hot acid pickling tank is not in use, further reducing acid mist leakage.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0023] A device frame for reducing acid mist leakage, such as Figures 1-7 As shown, the system includes a frame body 1, within which a loading station 2, a treatment tank 3, and a unloading station 4 are sequentially arranged. No doors 5 are provided at the loading station 2 or the unloading station 4. A partition 6 is also installed inside the frame body 1, with a transition groove on the partition 6. A connection hole 11 is provided on the frame body 1, connecting to an acid mist collection and treatment device. The acid mist collection and treatment device is a conventional device that uses negative pressure to extract and collect the acid mist inside the frame body 1, preventing environmental pollution. The partition 6 separates the inside and outside of the frame body 1, externalizing the drive mechanisms and connecting them to an internal cage via the transition groove, controlling the movement of the cage between the stations. This reduces acid mist leakage and protects the external equipment, extending its service life.
[0024] In one embodiment, such as Figures 1-7 As shown, a rubber sheet 62 is attached to the transition groove. The rubber sheet 62 is elastic, and when the connector passes through the transition groove, the rubber sheet 62 adheres tightly to the surface of the connector to reduce the size of the gap. In addition, the rubber sheet 62 has good corrosion resistance.
[0025] In one embodiment, such as Figures 1-7 As shown, the treatment tank 3 includes a hot pickling tank 31, a neutralization tank 32, and a cleaning tank 33 arranged sequentially. The number of treatment tanks 3 is set according to the product processing steps. In this embodiment, hydrochloric acid is added to the hot pickling tank 31 to perform hot pickling on the surface of the steel balls. After a set time, the tank is moved to the neutralization tank to neutralize the acid remaining on the surface of the steel balls. Finally, the tank is moved to the cleaning tank to clean the liquid remaining on the surface of the steel balls from the neutralization tank.
[0026] like Figures 1-7 As shown, the equipment frame also includes a partition component 7, which is installed between the loading station 2, the unloading station 4 and the processing pool 3, and uses the partition component 7 to separate the loading area, the unloading area and the processing area.
[0027] In the above embodiments, such as Figures 1-7 As shown, the partition assembly 7 includes a rotating shaft 71, a partition plate 72, and a servo motor 73. The rotating shaft 71 is mounted on the frame body 1, and the partition plate 72 is fixed on the rotating shaft 71. The servo motor 73 drives the rotating shaft 71 to rotate, thereby causing the partition plate 72 to rotate.
[0028] One usage step of the above embodiment: as follows Figures 1-7 As shown, to reduce the diffusion of acid mist from the hot pickling tank, the opening of the hot pickling tank 31 is covered by the partition plate 72 of the partition assembly 7; that is, the partition plate 72 covers the hot pickling tank 31. After the hoisting mechanism loads the material, it moves to above the neutralization tank 32. Once the partition plate 71 of the partition assembly 7 rotates to a vertical position, the hoisting mechanism moves the product into the hot pickling tank 31. After completion, it moves the product into the neutralization tank 32, and the partition assembly 7 operates again to cover the hot pickling tank 31. After the neutralization tank 32 is completed, the product is moved to the cleaning tank 33 for surface cleaning. Throughout the above steps, the other partition assembly 7 remains in a partitioned state, i.e., the partition plate 72 is in a vertical position, separating the processing area from the unloading area. When unloading, the servo motor 73 drives the partition plate 72 to rotate to the unloading station 4. After completion, the hoisting mechanism moves to the unloading station for manual unloading. Of course, the hoisting mechanism can first move to above the neutralization tank 32, and the partition plate 72 of another partition component 7 rotates and covers the cleaning tank 33. The hoisting mechanism moves the product to the unloading station 4, and the partition plate 72 of the partition component 7 returns to a vertical position, separating the processing area from the unloading area. The external acid mist collection and treatment equipment operates, drawing away the acid mist inside the frame body 1 through the connection hole 11. Even after the chamber door is opened, acid mist leakage can be effectively reduced.
[0029] In one embodiment, such as Figures 1-7 As shown, the partition plate 72 is fixed to the rotating shaft 71 by screws. Preferably, a rubber washer 74 is provided between the partition plate 72 and the rotating shaft 71, and between the screw and the partition plate 72. After the screw is tightened, the rubber washer is tightly attached to the pressing surface of the partition plate 72 and the rotating shaft 71, and between the screw and the partition plate 72, effectively preventing acid mist from entering the mounting hole of the rotating shaft and causing corrosion of the mounting hole.
[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present utility model.
