Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal material surface treatment technology, and more specifically, to a continuous hot-dip galvanizing device for galvanized steel wire. Background Technology
[0002] Galvanized steel wire is widely used in many fields such as construction, communications, transportation, and power engineering due to its excellent corrosion resistance, mechanical strength, and long service life. Its production quality directly affects the reliability and safety of downstream products. Hot-dip galvanizing is one of the core technologies in the production of galvanized steel wire. By immersing the steel wire in molten zinc to form a zinc coating, effective protection of the steel wire is achieved.
[0003] Existing continuous hot-dip galvanizing equipment for steel wire still has many shortcomings in practical applications: First, the pretreatment cleaning process for steel wire is mostly a single rinsing structure with uneven distribution of high-pressure nozzles. The cleaning solution cannot fully cover the surface of the steel wire, resulting in residual impurities such as oxide scale and oil, which directly affects the adhesion between the subsequent coating and the steel wire substrate, easily leading to problems such as coating peeling and blistering. Second, the cleaning solution circulation system lacks an efficient filtration mechanism. The accumulation of impurities not only reduces the cleaning effect but also increases equipment wear. Moreover, the installation and disassembly of filter plates are cumbersome, resulting in low maintenance efficiency. Third, the spraying of the plating solution in the immersion zone is uneven, and the zinc solution concentration is unbalanced in some areas, resulting in a large deviation in the thickness of the steel wire coating and affecting product consistency.
[0004] To address the aforementioned issues, a continuous hot-dip galvanizing device for galvanized steel wire is proposed. Summary of the Invention
[0005] To solve the above-mentioned technical problems, a continuous hot-dip galvanizing device for galvanized steel wire is provided.
[0006] To achieve the above objectives, the present invention can be implemented using the following technical solutions: This utility model provides a continuous hot-dip galvanizing device for steel wire, comprising: a device body, a partition fixedly installed in the middle of the inner side of the device body, one side of the partition being a cleaning zone and the other side being a galvanizing zone, a cleaning rack fixedly installed on the top of the cleaning zone of the device body, a diverter plate fixedly installed on the top of the cleaning rack, a connecting hose fixedly installed in the middle of the top side of the diverter plate, a water pump box fixedly installed at the end of the connecting hose away from the diverter plate, the water pump box fixedly installed to one side wall of the cleaning rack, a circulation pipe fixedly installed at the bottom of the water pump box, multiple sets of evenly distributed high-pressure nozzles fixedly installed on the top of the inner side of the cleaning rack, a drain pipe fixedly installed on the outer wall of the cleaning zone of the device body, a filter plate slidably installed on the outer wall of the device body away from the drain pipe, a rubber pad adhered to one end of the filter plate, and a limit strip rotatably connected to the outer wall of the device body near the rubber pad, the limit strip limiting the filter plate.
[0007] Preferably, a plurality of evenly distributed magnetic sheets are fixedly installed on the outer periphery of the rubber pad, the outer wall of the device body is made of iron material, and a cleaning wheel is fixedly installed on the top of the device body, the cleaning wheel having a plurality of evenly distributed cleaning grooves.
[0008] Preferably, an immersion plating rack is fixedly installed on the top of the immersion plating area of the device body, a diversion plate II is fixedly installed on the top of the immersion plating rack, a connecting hose II is fixedly installed on the top of the diversion plate II, a water pump box I is fixedly installed on the side of the connecting hose II away from the diversion plate II, the water pump box I is fixedly installed to one side wall of the immersion plating rack, a circulation pipe I is fixedly installed at the bottom of the water pump box I, a drain pipe II is fixedly installed on one outer wall of the immersion plating area of the device body, and multiple evenly distributed nozzles are fixedly installed on the top inner side of the immersion plating rack.
[0009] Preferably, multiple evenly distributed guide wheels are symmetrically installed on both sides of the device body.
[0010] Preferably, a guide plate is fixedly installed on the top of the device body, and a plurality of evenly distributed wire grooves are opened in the middle of the guide plate. The guide plate is fixedly installed directly below the immersion plating rack.
[0011] As described above, the features and advantages of the continuous hot-dip galvanizing device for galvanized steel wire in this utility model are: The cleaning zone uses multiple sets of evenly distributed high-pressure nozzles in conjunction with a flow divider plate to ensure that the cleaning fluid evenly covers the surface of the steel wire, effectively removing impurities such as oxide scale and oil. Combined with the scraping action of the cleaning groove on the top cleaning wheel, double cleaning avoids impurity residue, significantly improves the adhesion between the subsequent coating and the steel wire substrate, and reduces quality problems such as coating peeling and bulging.
[0012] The filter plates that slide in the cleaning area can effectively filter impurities in the cleaning fluid, and the sealing effect of the rubber gasket prevents leakage. The magnetic sheet and the iron device body are attracted together, and the quick-limiting design of the superimposed limit strip makes it possible to install and disassemble the filter plates without complicated tools, which greatly improves maintenance efficiency. At the same time, it avoids the accumulation of impurities and wear on the equipment, and extends the service life of circulation pipe 2 and water pump box 2.
[0013] The plating zone is evenly distributed with the plating solution by the second diversion plate, and multiple nozzles spray simultaneously. Combined with the first circulation pipe, the plating solution is recycled to ensure a uniform zinc concentration in the plating zone. The wire groove of the lower guide plate precisely limits the steel wire, and with the smooth transmission of the guide wheels on both sides, the steel wire is prevented from deviating, so that the coating thickness deviation is controlled within a reasonable range and the consistency of product batches is improved.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0017] See Figures 1-3 As shown, this is an embodiment of the present invention. The continuous hot-dip galvanizing device for galvanized steel wire will be described in detail below: A continuous hot-dip galvanizing apparatus for galvanized steel wire, such as Figures 1-3As shown, the device includes: a device body 1, with a partition 23 fixedly installed on the inner center of the device body 1. One side of the partition 23 is a cleaning area, and the other side is an immersion plating area. A cleaning rack 4 is fixedly installed on the top of the cleaning area of the device body 1. A diversion plate 6 is fixedly installed on the top of the cleaning rack 4. A connecting hose 5 is fixedly installed on the top center of the diversion plate 6. A water pump box 21 is fixedly installed at the end of the connecting hose 5 away from the diversion plate 6. The water pump box 21 is fixedly installed on one side wall of the cleaning rack 4. A circulation pipe 22 is fixedly installed at the bottom of pump box 21. Multiple sets of evenly distributed high-pressure nozzles 3 are fixedly installed on the inner top of the cleaning rack 4. A drain pipe 17 is fixedly installed on the outer wall of the cleaning area of the device body 1. A filter plate 16 is slidably installed on the outer wall of the device body 1 on the side away from the drain pipe 17. A rubber pad 15 is adhered to one end of the filter plate 16. A limit strip 13 is rotatably connected to the outer wall of the device body 1 on the side near the rubber pad 15. The limit strip 13 limits the filter plate 16, thus controlling the steel wire to be plated. One end passes through the guide wheel 2 on one side of the device body 1. Multiple evenly distributed guide wheels 2 form a stable transmission path, ensuring the steel wire smoothly enters the device horizontally, preventing deviation or shaking during transmission. After the steel wire enters the cleaning zone, the water pump box 21 is activated, and the cleaning fluid is delivered to the diversion plate 6 via the connecting hose 5. (The core working principle of the diversion plate is to achieve media diversion, merging, or guidance through internal flow channel design, while ensuring flow / pressure uniformity. Multiple symmetrical or custom-designed flow channels are pre-set inside to evenly divide the media into multiple branches. The distributed media flows out from multiple outlets, accurately delivering to the corresponding downstream equipment or channel.) After being evenly distributed by the diversion plate 6, high-pressure water is sprayed onto the steel wire surface by multiple high-pressure nozzles 3 on the top inner side of the cleaning rack 4, efficiently washing away scale, oil, and other impurities. Simultaneously, the cleaning wheel 7 on the top of the device body 1 rotates synchronously with the steel wire transmission, and its surface cleaning grooves scrape and clean the steel wire surface, achieving "high-pressure rinsing +..." The "physical scraping" double cleaning ensures the pretreatment effect. The waste liquid after cleaning carries impurities to the bottom of the cleaning area. After being filtered by the filter plate 16, it flows back to the water pump box 21 through the circulation pipe 22, realizing the recycling of the cleaning liquid.
[0018] Furthermore, such as Figures 1-3 As shown, multiple evenly distributed magnetic sheets 14 are fixedly installed on the outer periphery of the rubber pad 15. The outer wall of the device body 1 is made of iron. A cleaning wheel 7 is fixedly installed on the top of the device body 1. The cleaning wheel 7 has multiple evenly distributed cleaning grooves. The filter plate 16 is attracted and attached to the iron device body 1 through the magnetic sheets 14 on the outer periphery of the rubber pad 15. It is fixed in place with the limiting strip 13 to ensure no leakage during the filtration process. The filter plate 16 can be quickly disassembled for cleaning and maintenance by rotating the limiting strip 13.
[0019] Furthermore, an immersion plating rack 11 is fixedly installed on the top of the immersion plating area of the device body 1. A diversion plate 2 9 is fixedly installed on the top of the immersion plating rack 11. A connecting hose 2 10 is fixedly installed on the top of the diversion plate 2 9. A water pump box 20 is fixedly installed on the side of the connecting hose 2 10 away from the diversion plate 2 9. The water pump box 20 is fixedly installed on one side wall of the immersion plating rack 11. A circulation pipe 19 is fixedly installed at the bottom of the water pump box 20. A drain pipe 2 18 is fixedly installed on one outer wall of the immersion plating area of the device body 1. Multiple evenly distributed nozzles 8 are fixedly installed on the top inner side of the immersion plating rack 11. Multiple evenly distributed guide wheels 2 are symmetrically installed on both sides of the device body 1. A guide plate 12 is fixedly installed on the top of the device body 1. Multiple evenly distributed wire grooves are opened in the middle of the guide plate 12. The guide plate 12 is fixedly installed directly below the immersion plating rack 11. The pre-treated steel wire passes through the partition 23 and enters the immersion plating area. When the guide plate 12 is in operation, the wire groove in its middle precisely limits the position of the steel wire, ensuring that the steel wire is directly below the immersion rack 11, providing positional assurance for uniform immersion. The water pump box 20 is started, and the molten zinc liquid is transported to the diversion plate 9 through the connecting hose 10. After being evenly distributed by the diversion plate 9, the zinc liquid is simultaneously sprayed onto the surface of the steel wire by multiple nozzles 8 inside the immersion rack 11, achieving full coverage. At the same time, the circulation pipe 19 returns the zinc liquid at the bottom of the immersion zone to the water pump box 20, maintaining a balanced concentration of the plating solution and ensuring that the coating thickness of the steel wire is uniform. The steel wire that has completed immersion is smoothly discharged through the guide wheel 2 on the other side of the device body 1, forming a finished galvanized steel wire. Waste liquid or excess plating solution generated during the immersion process is centrally discharged and treated through the drain pipe 18, while waste liquid from the cleaning area is discharged through the drain pipe 17, achieving environmentally friendly treatment.
[0020] Specifically, one end of the steel wire to be plated is passed through the guide wheel 2 on one side of the device body 1. Multiple evenly distributed guide wheels 2 form a stable transmission path, ensuring the steel wire smoothly enters the device horizontally, preventing deviation or shaking during transmission. After the steel wire enters the cleaning area, the water pump tank 21 is activated, and the cleaning solution is delivered to the distribution plate 6 through the connecting hose 5. After being evenly distributed by the distribution plate 6, high-pressure water is sprayed onto the surface of the steel wire from multiple high-pressure nozzles 3 on the inner top of the cleaning rack 4, efficiently washing away scale, oil, and other impurities. Simultaneously, the cleaning wheel 7 on the top of the device body 1 rotates synchronously with the steel wire transmission, and its surface cleaning grooves perform abrasive cleaning on the steel wire surface, achieving "high-pressure rinsing + physical abrasion". Double cleaning ensures effective pretreatment. The waste liquid, carrying impurities, flows to the bottom of the cleaning zone, is filtered by filter plate 16, and then returns to pump box 21 via circulation pipe 22, achieving recycling of the cleaning liquid. Filter plate 16 is adhered to the iron device body 1 by magnetic sheets 14 on the outer periphery of rubber pad 15, and fixed by limiting strip 13, ensuring no leakage during filtration. The filter plate 16 can be quickly disassembled for cleaning and maintenance by rotating the limiting strip 13. The pretreated steel wire passes through partition 23 into the immersion plating zone. When passing the guide plate 12 at the top of the device body 1, the wire groove in the middle precisely limits the steel wire, ensuring it is directly below the immersion plating rack 11, improving uniform plating. To ensure proper positioning, the water pump box 20 is activated, and the molten zinc liquid is transported to the distribution plate 9 through the connecting hose 10. After being evenly distributed by the distribution plate 9, the zinc liquid is simultaneously sprayed onto the surface of the steel wire by multiple nozzles 8 inside the immersion rack 11, achieving full coverage. At the same time, the circulation pipe 19 returns the zinc liquid at the bottom of the immersion zone to the water pump box 20, maintaining a balanced concentration of the plating solution and ensuring a uniform coating thickness for the steel wire. The steel wire that has completed immersion plating is smoothly discharged through the guide wheel 2 on the other side of the device body 1, forming a finished galvanized steel wire. Waste liquid or excess plating solution generated during the immersion plating process is centrally discharged and treated through the drain pipe 18, while waste liquid from the cleaning area is discharged through the drain pipe 17, achieving environmentally friendly treatment.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
