Description

Technical Field

[0001] This utility model belongs to the field of degreasing technology for hot-dip galvanized parts, and particularly relates to a degreasing device for hot-dip galvanizing. Background Technology

[0002] Hot-dip galvanizing, as a highly efficient and durable metal surface treatment method, relies on the chemical reaction between molten metal and the iron substrate to form a robust alloy layer. This not only achieves a tight bond between the coating and the substrate but also endows the coated parts with a uniform and aesthetically pleasing appearance, strong adhesion, and a long service life. The ingenuity of this process lies in its meticulous arrangement of steps, from degreasing and oil removal, pickling and rust removal to final drying and inspection; each step is crucial.

[0003] In the degreasing and oil removal process, a crucial pretreatment step before hot-dip galvanizing, the purpose is to thoroughly remove water-insoluble impurities such as grease and dirt adhering to the surface of steel parts. If these impurities are not effectively removed, they will severely interfere with subsequent rust removal, the penetration of solvent-assisted plating, and the uniformity and adhesion of the hot-dip galvanized layer. However, traditional brush scraping degreasing methods have significant limitations: on the one hand, grease and debris easily accumulate inside the brush, and if not properly maintained, these contaminants may repeatedly contaminate the workpiece surface; on the other hand, the physical contact method of the brush makes it difficult to reach the tiny crevices and complex structures on the workpiece surface, limiting its cleaning effect, especially for precision or specially shaped parts.

[0004] Therefore, it is essential to invent a degreasing device for hot-dip galvanizing. Utility Model Content

[0008] Preferably, the placement mesh frame is provided with numerous gaps or through holes that allow liquid flow, and the placement mesh frame is located between the two wave-making undulation mechanisms and above the hot-dip galvanizing degreasing machine box.

[0009] Preferably, the bubble-generating tube is a serpentine bend, and the bubble-generating tube has numerous through holes that allow high-pressure gas to pass through, through which the high-pressure gas is injected into the liquid medium inside the cleaning tank.

[0021] As attached Figure 1 To be continued Figure 3 As shown:

[0022] This utility model provides an oil removal device for hot-dip galvanizing, including a hot-dip galvanizing oil removal machine box 1, a wave-making undulation mechanism 2, and a component placement mesh frame 3. The wave-making undulation mechanism 2 is installed on the hot-dip galvanizing oil removal machine box 1. There are two wave-making undulation mechanisms 2, and the two wave-making undulation mechanisms 2 are fixedly connected to the component placement mesh frame 3.

[0023] The hot-dip galvanizing degreasing chamber 1 includes a cleaning tank 11, a bubble-generating pipe 12, support plates 13, and a drive motor 14. The bubble-generating pipe 12 is installed inside the lower part of the cleaning tank 11 and is connected to a high-pressure pipeline. Four support plates 13 are fixedly installed on the cleaning tank 11, and the drive motor 14 is fixedly installed on the outside of the support plates 13. The output end of the drive motor 14 is fixed to the wave-making mechanism 2. The hot-dip galvanizing degreasing chamber 1 can perform efficient cleaning treatment on the workpiece through the generated high-pressure bubbles.

[0024] The wave-making mechanism 2 includes a drive disk 21, a connecting shaft 22, a drive rod 23, a connecting seat 24, a horizontal plate 25, and a wave head 26. Two drive disks 21 are provided; one drive disk 21 is fixed to the output end of the drive motor 14, and the other drive disk 21 is rotatably mounted on the support plate 13. The connecting shaft 22 is fixedly mounted on both drive disks 21, and the connecting shaft 22 is rotatably connected to the two drive rods 23 respectively. The lower end of the connecting shaft 22 is rotatably connected to the connecting seat 24, which is fixedly mounted on the horizontal plate 25. The horizontal plate 25 is fixedly connected to the wave head 26 and the placement mesh frame 3 respectively. The reciprocating motion of the wave-making mechanism 2 can create undulating waves in the liquid, further improving the cleaning effect and allowing the bubbles to move over a wider range.

[0025] Example 1:

[0026] In this embodiment, the hot-dip galvanizing degreasing chamber (1) is the core component of the entire system, with an ingenious internal design to achieve efficient degreasing and oil removal. The cleaning tank 11, as the main body, accommodates most of the cleaning operations. A crucial component—the placement mesh frame 3—is installed above the cleaning tank 11. The placement mesh frame 3 is designed with numerous gaps or through-holes, allowing the cleaning fluid to flow freely and ensuring that the cleaning fluid can comprehensively and evenly cover and act on the surface of the steel parts placed on the mesh frame. The placement mesh frame 3 is located between two wave-making undulation mechanisms 2; this layout helps to maximize the wave effect generated by the wave-making undulation mechanisms, improving the cleaning effect.

[0027] To further enhance the cleaning effect, a serpentine bend serves as a bubble-generating pipe 12 inside the cleaning tank 11. This bubble-generating pipe 12 is covered with tiny through-holes. When high-pressure gas is injected into the liquid medium inside the cleaning tank 11 through these through-holes, a large number of microbubbles are rapidly formed. These microbubbles can more effectively penetrate and peel off grease and dirt from the surface of steel parts, playing a crucial role in the degreasing process.

[0028] The wave-generating mechanism 2 is another highlight of this embodiment. The drive disc 21 is located inside the support plate 13 and is rotatably connected to the support plate 13 via a spindle. When the drive motor 14 starts, it drives the drive disc 21 to rotate, which in turn causes the wave generator 26 to reciprocate up and down on the inner wall of the cleaning tank 11 through a series of mechanical transmissions. This reciprocating motion creates a dynamic wave effect in the liquid medium inside the cleaning tank 11, greatly enhancing the flushing and penetrating power of the cleaning fluid.

[0029] Of particular note is the design of the wave generator 26. It not only slides onto the inner wall of the cleaning tank 11 but also features a ramp. This ramp cuts into the water surface and compresses and propels the liquid medium as the wave generator 26 moves up and down, creating strong wave impacts. This design allows the cleaning fluid to penetrate deeper into the tiny gaps and complex structures of steel components, achieving a more comprehensive and thorough cleaning.

[0030] Example 2:

[0031] Preparation stage: Place the steel parts to be cleaned on the mesh frame 3, ensuring good contact between the surface of the parts and the cleaning solution. At this time, an appropriate amount of cleaning solution has been injected into the cleaning tank 11.

[0032] Foaming and Penetration: A high-pressure gas source is activated, and high-pressure gas is injected into the liquid medium within the cleaning tank 11 through tiny orifices on the foaming tube 12. This gas rapidly forms numerous microbubbles, which diffuse throughout the liquid and penetrate into the minute crevices and complex structures of the steel workpiece surface. The bursting effect and surface tension of the microbubbles help to peel off and suspend grease and dirt from the workpiece surface.

[0033] Wave generation: Simultaneously, the drive motor starts, causing the drive disc 21 of the wave generation mechanism 2 to rotate. Through mechanical transmission of components such as connecting shafts, drive rods, connecting seats, and cross plates, the drive disc 21 causes the wave generator 26 to reciprocate up and down on the inner wall of the cleaning tank 11. During this process, the inclined design of the wave generator 26 allows it to cut into the water surface and squeeze and push the liquid medium, thereby creating a strong wave effect inside the cleaning tank.

[0034] Wave scouring and penetration: The up-and-down movement and impact force of waves greatly enhance the scouring and penetrating power of the cleaning fluid. Waves not only distribute the cleaning fluid more evenly across the surface of the workpiece, but also, through their dynamic characteristics, promote deep penetration of the cleaning fluid into tiny gaps and complex structures. This scouring and penetrating effect further enhances the degreasing and oil removal effect.

[0035] Cleaning Completion and Subsequent Processing: After a period of cleaning, the grease and dirt on the surface of the steel parts are effectively removed. At this point, the high-pressure gas source and drive motor can be turned off, and the parts can be removed from the placement frame 3 for subsequent hot-dip galvanizing or other operations. Simultaneously, the cleaning solution in the cleaning tank 11 can be treated and reused through a recycling system to reduce wastewater generation and discharge.

[0036] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
