Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot-dip galvanizing tank technology, and more specifically, it relates to a circulating hot-dip galvanizing tank with a filtration device. Background Technology
[0002] In existing technologies, the existing circulating hot-dip galvanizing tanks with filtration devices typically only have one filter component, which undertakes all the work of filtering the zinc liquid during equipment operation. However, during use, the filter component will gradually become clogged due to the long-term interception of impurities in the zinc liquid. Once clogged, the flow of zinc liquid is hindered, the filtration function cannot be performed normally, and the normal operation of the galvanizing tank is directly affected.
[0003] Existing galvanizing tank structures are relatively simple, typically consisting of only a static tank. The natural flow of the liquid inside the tank is poor, and there is a lack of effective circulation and stirring devices. Due to the lack of stirring tools, it is difficult for the molten zinc in the tank to achieve uniform flow, especially near the parts. The temperature of the molten zinc will drop due to heat transfer, forming local low-temperature areas. This temperature difference directly affects the quality of the galvanized layer, which may lead to uneven coating thickness or reduced coating adhesion, thus failing to achieve the expected anti-corrosion effect.
[0004] In current filtration devices, the filter screen is the main component for intercepting impurities in molten zinc. Although it can remove some impurities from the molten zinc, its cleaning and maintenance remains a major bottleneck for existing devices. The filter screen is mainly used to filter zinc oxide particles and iron impurities in molten zinc. However, due to the uneven particle size of iron impurities, some larger iron impurities will get stuck in the pores of the filter screen. This situation is quite common during the filtration process. Utility Model Content

[0016] (III) Beneficial Effects
[0017] Compared with the prior art, this utility model provides a circulating hot-dip galvanizing tank with a filtration device, which has the following advantages:
[0018] 1. The diversion component achieves efficient circulation of fluid between the tank and the filter box through the linkage of the water pump and the U-tube.

[0019] 2.

[0032] Please see Figures 1-7 A circulating hot-dip galvanizing tank with a filtration device includes a fixed frame 1. A diversion assembly is provided on the fixed frame 1. The diversion assembly includes a tank body 2, a filter box 3, a U-shaped pipe 4, a water pump 5, and a connecting pipe 6. The tank body 2 is set on the fixed frame 1. The filter box 3 is set at one end of the tank body 2. There are two filter boxes 3. The U-shaped pipe 4 is connected to the bottom of the filter box 3. A control valve is externally connected to the U-shaped pipe 4. The water pump 5 is connected to the U-shaped pipe 4. The connecting pipe 6 connects the water pump 5 and the tank body 2. A stirring assembly is provided on the tank body 2. The stirring assembly includes a top plate 7, a first motor 8, and a rotating rod 9. The top plate 7 is fixedly installed on the top of the tank body 2. The first motor 8 is fixedly installed on the top plate 7. The rotating rod 9 is connected to the output end of the first motor 8.
[0033] A sealing plug 10 is detachably installed on the filter box 3, and a second threaded rod 11 is threadedly connected to the filter box 3.
[0034] A scraper 12 is connected to the second threaded rod 11. The scraper 12 is in close contact with the bottom of the filter box 3. A guide rod 13 is fixedly installed in the filter box 3. The guide rod 13 is slidably connected to the scraper 12.
[0035] A rotating blade 14 is connected to the rotating rod 9, and connecting rods 15 are evenly connected to the rotating rod 9.
[0036] A toggle plate 16 is connected to the connecting rod 15.
[0037] In this embodiment, during use, the water pump 5 is started to introduce the fluid in the tank 2 along the connecting pipe 6 and the U-shaped pipe 4 into the filter box 3. The water flow is controlled by the external control valve on the U-shaped pipe 4, so that if the filter plate 17 in one filter box 3 is blocked and cannot be used, another filter box 3 can be used for filtration. As the fluid is continuously introduced, the liquid level rises until the entire filter box 3 is filled. Then, under the action of the pump body 22, the fluid is reintroduced into the tank 2 for circulation. When it is necessary to stir the fluid inside the tank 2, the first motor 8 is started to drive the rotating rod 9 at the output end to rotate. During the rotation, the rotating blade 14 on it rotates, thereby completing the stirring process of the liquid at the top. During the continuous rotation, the connecting rod 15 at the bottom rotates, which drives the actuating plate 16 on it to rotate, thus completing the stirring and homogenization process of the liquid.
[0038] Please see Figure 5-7 As an embodiment of a circulating hot-dip galvanizing tank with a filter device for a vibration component: a vibration component is provided on the filter box 3. The vibration component includes a filter plate 17, a spring 18, and a second motor 19. The filter plate 17 is slidably connected inside the filter box 3. The spring 18 is evenly connected between the filter plate 17 and the filter box 3. The second motor 19 is fixedly installed on the filter box 3.
[0039] The output end of the second motor 19 is connected to a cam 20. Multiple cams 20 are provided. One end of the cam 20 is in close contact with the filter plate 17. A return pipe 21 is connected between the top trough 2 of the filter box 3.
[0040] A pump body 22 is installed on the return pipe 21.
[0041] More specifically, as the liquid in the filter box 3 rises continuously, large impurities on it will be filtered out by the filter plate 17 and will adhere to the filter plate 17. At this time, by starting the second motor 19, it drives the cam 20 on it to rotate. As it rotates, it comes into contact with the filter plate 17. During the rotation of the cam 20, it causes the filter plate 17 to compress the spring 18 at its bottom, thereby causing the filter plate 17 to move up and down, causing the impurities to fall off. Finally, the sealing plug 10 is removed, and the second threaded rod 11 is driven to rotate, thereby causing the scraper 12 on it to slide along the guide rod 13, thereby scraping off the impurities.
[0042] In summary, during the use or operation of the overall equipment: During use, the water pump 5 is started, and the fluid in the tank 2 is introduced into the filter box 3 along the connecting pipe 6 and the U-shaped pipe 4. The water flow is controlled by the external control valve on the U-shaped pipe 4, so that if the filter plate 17 in one filter box 3 becomes clogged and unusable, another filter box 3 can be used for filtration. As the fluid is continuously introduced, the liquid level rises until the entire filter box 3 is filled. Then, under the action of the pump 22, the fluid is reintroduced into the tank 2, creating a circulation process. When it is necessary to agitate the fluid inside the tank 2, the first motor 8 is started, causing the rotating rod 9 at the output end to rotate. During this rotation, the rotating blade 14 on the motor rotates, thus agitating the liquid at the top. Furthermore, during this continuous rotation, the connecting rod 15 at the bottom rotates, causing the actuating plate 16 on it to rotate, ensuring thorough and uniform agitation of the liquid.
[0043] As the liquid in the filter box 3 rises continuously, large impurities on it will be filtered out by the filter plate 17 and will adhere to the filter plate 17. At this time, the second motor 19 is started, which drives the cam 20 on it to rotate. As the cam rotates, it comes into contact with the filter plate 17. During the rotation of the cam 20, the filter plate 17 is compressed against the spring 18 at its bottom, which causes the filter plate 17 to move up and down, causing the impurities to fall off. Finally, the sealing plug 10 is removed, which drives the second threaded rod 11 to rotate, causing the scraper 12 on it to slide along the guide rod 13, thereby scraping off the impurities.
[0044] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
