Description

Technical Field

[0001] This utility model relates to the field of galvanizing equipment, and more specifically, to a high-strength steel galvanizing equipment. Background Technology

[0002] High-strength steel galvanizing is a process that provides corrosion protection for high-strength steel. By immersing high-strength steel in molten zinc or using electrolysis, a zinc coating is formed on its surface. This coating protects the steel substrate through sacrificial anodic action, delaying corrosion. It is particularly suitable for applications such as automobiles and construction machinery, where both steel strength and weather resistance are critical. The process must consider the mechanical properties of the high-strength steel, avoiding strength reduction due to high temperatures or improper handling, while ensuring a uniform coating with strong adhesion, balancing the protective effect with the material's inherent properties.

[0003] Galvanizing typically involves placing steel wire inside galvanizing equipment. However, existing galvanizing equipment often produces impurities floating on the surface of the galvanized solution. These impurities usually originate from residual oil from incomplete pretreatment of the workpiece or lubricating oil introduced during equipment maintenance. These impurities have low density and easily float on the surface. If they adhere to the workpiece surface, they can cause defects such as pinholes and peeling in the coating. These impurities are usually manually removed to prevent them from adhering to the steel wire and causing poor galvanizing quality, resulting in low efficiency. Therefore, we propose a high-strength steel galvanizing equipment. Utility Model Content

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A high-strength steel galvanizing equipment includes a galvanizing tank 1, a return box 2 fitted on the outer surface of the galvanizing tank 1, a diversion channel 3 formed on the upper surface of the return box 2, the bottom wall of the diversion channel 3 being inclined, a filter plate 4 provided on the inner wall of the diversion channel 3, a pump body 5 fixedly connected to the lower surface of the return box 2, a return pipe fixedly connected to the output end of the pump body 5, the return pipe communicating with the interior of the galvanizing tank 1, and an overflow channel 6 formed on the upper surface of the galvanizing tank 1, the bottom wall of the overflow channel 6 being inclined. An expansion bubble 7 is fixedly connected to the bottom wall of the galvanizing tank 1. An air pump 8 is fixedly connected to the right side surface of the galvanizing tank 1. A transmission pipe 9 is fixedly connected to the output end of the air pump 8. The end of the transmission pipe 9 is connected to the interior of the expansion bubble 7. A fixing component is provided on the filter plate 4. When floating impurities appear on the surface of the galvanizing tank 1, the upper zinc liquid can be pushed out through the overflow trough 6 by the slow expansion of the expansion bubble 7. Thus, the flow of the zinc liquid drives the impurities out. At the same time, the impurities can be separated by the filter plate 4.

[0029] Example 2

[0030] The high-strength steel galvanizing equipment provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the fixing assembly includes a hook 10, which is fixedly connected to the upper surface of the filter plate 4. An overflow plate 11 is fixedly connected to the upper surface of the galvanizing tank 1. The overflow plate 11 is U-shaped, and the hook 10 is hung on the overflow plate 11. Two mounting plates 12 are fixedly connected to the left and right sides of the return box 2, respectively. An mounting rod 13 is fixedly connected between two adjacent mounting plates 12. A galvanizing frame 14 is fitted onto the outer surface of the mounting rod 13. The galvanizing frame 14 is U-shaped, and a hydraulic push rod 15 is fixedly connected to the upper surface of the horizontal plate of the galvanizing frame 14. The lower end of the hydraulic push rod 15 slides... The hydraulic push rod 15 extends through the lower surface of the horizontal plate of the galvanizing rack 14. The lower end of the hydraulic push rod 15 is fixedly connected to the displacement plate 16. Guide grooves 17 are opened on the adjacent side surfaces of the two vertical plates of the galvanizing rack 14. Guide blocks 18 are fixedly connected to the left and right sides of the displacement plate 16 respectively. The guide blocks 18 are slidably connected inside the guide grooves 17. The lower surface of the displacement plate 16 is fixedly connected to the hanging ears 19. Not only can the spill plate 11 be used to avoid the waste caused by zinc liquid dripping, but the displacement plate 16 and the hanging ears 19, together with the hydraulic push rod 15, can also be used to sink a batch of workpieces into the zinc liquid to complete the galvanizing work.

[0031] The expansion bubble 7 is made of cobalt-based alloy Haynes 188 with a wall thickness of 4 mm. It has good elongation and good resistance to zinc liquid corrosion.

[0032] The high-strength steel galvanizing equipment provided by this utility model is used as follows:

[0033] When impurities float on the surface of the galvanizing tank 1, gas can be injected into the expansion bubble 7 through the air pump 8 and the transmission pipe 9, causing the expansion bubble 7 to expand. After expansion, the expansion bubble 7 squeezes out some of the galvanizing tank 1. When the galvanizing liquid flows out through the overflow trough 6, it also moves the impurities floating on the surface. The overflowing galvanizing liquid enters the interior of the guide trough 3 through the overflow trough 6. After being filtered by the filter plate 4, the impurities remain on the upper side of the filter plate 4, while the galvanizing liquid is guided by the guide trough 3 and accumulates at the lowest point, i.e., above the pump body 5. After cleaning, the expansion bubble 7 is evacuated to remove the internal gas. This causes the expansion bubble 7 to restore the liquid level to drop. At this time, the zinc liquid inside the diversion tank 3 is injected back into the galvanizing tank 1 through the return pipe by the pump body 5 to achieve liquid level balance. At the same time, when the filter plate 4 becomes partially clogged after a period of filtration, it can be directly removed and cleaned by the hook 10. Meanwhile, the anti-overflow plate 11 can prevent the zinc liquid from spilling outside. When galvanizing high-strength steel parts, the workpiece can be suspended on the hanging ear 19, and then the displacement plate 16 can be lowered by starting the hydraulic push rod 15 to sink the workpiece into the zinc liquid.
