[0002] Hot-dip galvanizing tanks are where workpieces undergo hot-dip galvanizing. In existing technology, these tanks are mostly constructed from steel plates, where a heating plate heats the zinc solution to the required temperature for the galvanizing process. This presents several challenges: the zinc solution in the tank easily corrodes the steel plates, while the temperature of the zinc solution drops rapidly, affecting the effectiveness of the galvanizing process. Furthermore, the zinc solution in the tank must be maintained at approximately 450°C to complete the galvanizing of the workpieces. Such high temperatures create a significant amount of zinc fumes in the tank. If these fumes are not treated and allowed to evaporate into the air, they not only waste energy but also pollute the production environment and pose a health risk to workers. Utility Model Content

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1 to 4 As shown, this embodiment provides a hot dip galvanizing tank, comprising

[0026] The galvanizing tank body 1 is provided with a top plate 2 on the top cover of the galvanizing tank body 1;

[0027] The movable connecting component 5 is arranged between the galvanizing tank body 1 and the top plate 2;

[0028] Suction fan 3, the suction fan 3 is installed on the upper surface of the top plate 2;

[0029] The suction filter assembly 4 is arranged on the top plate 2. The suction filter assembly 4 includes an inner cavity 4-1, which is opened in the side surface of the top plate 2. An air inlet 4-2 is opened on the bottom surface of the inner cavity 4-1. A partition plate 4-3 is provided in the inner cavity 4-1. A filter plate 4-4 is inserted and connected in the inner cavity 4-1. The filter plate 4-4 is located at the bottom of the partition plate 4-3. A filter box 4-5 is installed on the upper surface of the top plate 2. A pair of mesh partitions 4-6 are provided in the filter box 4-5. A feeding port 4-7 is opened on the top of the filter box 4-5. A top cover 4-8 is inserted in the feeding port 4-7. A discharge port 4-9 is opened on the side surface of the filter box 4-5. The side surface of the filter box 4-5 is rotatably connected to the side cover 4-10 through a pin shaft. The filter box 4-5 is connected to the output end of the suction fan 3 by a pipe 4-11.

[0030] In this embodiment, in order to filter and purify the gas generated by the galvanizing tank body 1, a suction filter assembly 4 is designed, and an inner cavity 4-1 is opened inside the top plate 2. The inner cavity 4-1 is divided into an upper and lower side by a partition plate 4-3. The bottom is used to insert the filter plate 4-4, and the top interval is used to improve the gas collection and the filtering effect of the filter plate 4-4, so that all positions covered by the filter plate 4-4 can achieve the filtering effect. The upward-flowing air will enter the filter box 4-5, and the interior of the filter box 4-5 is spaced in the middle part by the mesh partition plate 4-6. Adsorption material, such as activated carbon, can be added to the interior of the filter box 4-5 at the feeding port 4-7. The gas is sucked by the suction fan 3 and achieves the adsorption and purification effect through the adsorption material during the flow process. Finally, the filtered and purified gas is discharged by the suction fan 3, and the filter plate 4-4 can be pulled outward for easy cleaning and replacement.

[0031] Specifically, in order to achieve the purpose of being able to quickly open and close the top plate 2 when picking up and placing workpieces, a mobile connection component 5 is designed to drive the top plate 2 to move laterally on the top of the galvanizing tank body 1, which can be quickly opened and closed.

[0032] Furthermore, the movable connection assembly 5 includes a guide frame 5-1, which is fixed on the opposite side surfaces of the galvanizing tank body 1, and the top plate 2 is connected to the guide frame 5-1 in a sliding sleeve. A rack 5-2 is provided on the lower end surface of the top plate 2, and a fixed plate 5-3 is provided on the side surface of the galvanizing tank body 1. A driving motor 5-4 is fixedly connected to the surface of the fixed plate 5-3, and a driving gear 5-5 is provided at the output end of the driving motor 5-4, and the driving gear 5-5 is meshed with the rack 5-2.

[0033] In this embodiment, guide frames 5-1 are provided on both sides of the galvanizing tank body 1, the top plate 2 is slidably connected to the guide frames 5-1, and a rack 5-2 is provided at the lower end of one side of the top plate 2. The rack 5-2 is meshed with a driving gear 5-5 driven to rotate by a driving motor 5-4 as power. The rack 5-2 can be driven by the rotation of the driving gear 5-5 to make the top plate 2 move laterally on the surface of the guide frame 5-1, so that the top plate 2 can achieve the effect of quick opening and closing.

[0034] Furthermore, the overall length of the top plate 2 is shorter than the galvanizing tank body 1, and a partial opening is left on one side of the top of the galvanizing tank body 1.

[0035] In this embodiment, a portion of opening is left at the top of the galvanizing tank body 1 to allow outside air to enter, thereby facilitating the extraction of gas inside the galvanizing tank body 1 .

[0036] Furthermore, the mesh partition 4-6 located at the upper end of the filter box 4-5 has an L-shaped cross section, and the mesh partition 4-6 located at the lower end of the filter box 4-5 is connected in an inclined manner.

[0037] In this embodiment, part of the interior of the filter box 4-5 is separated by two mesh partitions 4-6, and the feed port 4-7 and the discharge port 4-9 can be used to add fillers for adsorption. The inclined mesh partition 4-6 can be used to quickly discharge the failed fillers that need to be replaced, making it convenient to replace the fillers.

[0038] Furthermore, the length of the rack 5-2 is the same as the stroke length of the guide frame 5-1.

[0039] In this embodiment, the maximum movement of the top plate 2 and the area that can be covered by the galvanizing tank body 1 are limited by the stroke length of the rack 5-2 and the guide frame 5-1.

[0040] Furthermore, handles 6 are fixedly connected to the surfaces of the top cover 4-8 and the side cover 4-10.

[0041] In this embodiment, the top cover 4-8 and the side cover 4-10 are conveniently opened outward by the handle 6, and the top cover 4-8 and the side cover 4-10 are both sealed and connected to prevent the gas outside the galvanizing tank body 1 from being sucked in.

[0042] When it is necessary to suction and filter the gas in the galvanizing tank body 1, start the driving motor 5-4, drive the rack 5-2 through the driving gear 5-5 to move the top plate 2 horizontally and close it, then start the suction fan 3, collect gas through the air inlet 4-2, the gas is first filtered through the filter plate 4-4, and then enters the filter box 4-5, and is discharged after being adsorbed by the internal filler. After a period of use, the filter plate 4-4 can be pulled out for cleaning or directly replaced. The filler needs to be opened through the handle 6 to open the top cover 4-8 and the side cover 4-10. After the filler is discharged from the discharge port 4-9, new filler is added at the feeding port 4-7 to ensure the adsorption state.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
