Description

Technical Field

[0001] The invention relates to the technical field of galvanizing, and in particular to a plating bath device and method for producing hot-dip galvanized steel sheets. Background Art

[0002] With the continuous development of the national economy and the continuous advancement of science and technology, the demand for steel plates has greatly increased, and more and more places will use steel plates. However, steel plates are exposed to the air for a long time during use, which can easily cause the steel plates to rust and affect their use. In order to better protect the steel plates, the steel plates are galvanized using a plating bath device during the production process to form hot-dip galvanized steel plates, so that a protective film is formed on the surface of the steel plates, thereby slowing down the formation of rust. The production process of hot-dip galvanized steel plates mainly includes pretreatment, zinc immersion, cooling and other steps. In the pretreatment stage, the steel plate needs to be cleaned to remove oil, oxide layer and rust on the surface to ensure the adhesion of the galvanized layer. Pickling is a key step, which removes impurities on the surface of the steel plate through chemical reactions to make its surface smoother. Subsequently, through water washing and passivation steps, the surface of the steel plate is ensured to be clean and have good adhesion.

[0003] For example, the patent application with the prior art publication number CN118345323A discloses a hot-dip galvanizing device for high-pressure hardware bolt production in the field of bolt processing technology, including a processing table, wherein the first row of the processing table surface is provided with an alkali washing tank, a rust removal tank and a phosphating tank from left to right, and the second row of the processing table surface is provided with a galvanizing tank and a cleaning tank from left to right. By setting a stirring mechanism, the staff starts the electric push rod, and the electric push rod starts to move the shell downward, the first motor starts to drive the connecting rod to rotate, and the connecting rod drives the surface stirring rod to stir the bolt. The alkali washing tank and the cleaning brush are provided to remove oil stains on the surface of the bolt, the rust removal tank is provided to cooperate with the cleaning brush to remove rust on the surface of the bolt, and the phosphating tank is provided to perform phosphating treatment on the bolt to improve the adhesion and corrosion resistance of the galvanized layer, so as to achieve sufficient surface rust removal, degreasing and phosphating treatment before galvanizing the bolt, thereby improving the quality of galvanizing of the bolt.

[0004] In practical applications, although the prior art achieves effective pretreatment by setting up an alkaline washing tank and equipping a cleaning brush to remove oil stains on the surface of the material, there are still certain limitations in the specific operation process. In particular, when the order of alkaline washing first, rust removal and phosphating treatment is adopted, although this process improves the overall quality of the galvanized layer to a certain extent, we have also found some potential problems. Although the alkaline washing step is intended to completely remove the grease on the surface of the material, in actual operation, the grease may be intertwined with the rust and oxides on the surface of the material to form a composite layer that is difficult to peel off. In this case, the subsequent rust removal step will become extremely difficult, and the rust removal effect will be greatly reduced. To this end, the present application proposes a plating bath device and method for the production of hot-dip galvanized steel sheets. Summary of the invention

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figure 1 , Figure 2 as well as Figure 3 The present invention provides a technical solution: a hot-dip galvanized steel sheet production bath device, comprising a bathing pot 100 for galvanizing a steel sheet material 105 and a bracket 101, wherein a material roller 104 for winding the steel sheet material 105 is arranged on the top of the bracket 101, a pot guide roller 102 for guiding the steel sheet material 105 is rotatably connected inside the bathing pot 100, a bearing seat 103 for supporting the material roller 104 is fixedly connected to the top of the bracket 101, a dryer 107 for drying the steel sheet material 105 is fixedly connected above the bracket 101, and a roller 106 for guiding the steel sheet material 105 is arranged, and the interior of the bathing pot 100 is filled with a galvanizing solution. During the galvanizing process, the steel sheet material 105 is uniformly galvanized in the bathing pot 100 through the cooperation of the pot guide roller 102 and the roller 106.

[0042] See also Figure 4 , Figure 5 as well as Figure 6, and also includes a rust removal cleaning cylinder 200, which is arranged on the top of the bracket 101 and located on both sides of the steel plate material 105, and is used to remove rust from the steel plate material 105, and a plurality of nozzles and a brush body are opened at the bottom. The internal structure of the bracket 101 is equipped with a driving component for driving the rust removal cleaning cylinder 200 to swing and realize dynamic cleaning. By setting the driving component, the steel plate material 105 can be effectively and efficiently rust-removed, and both sides of the steel plate material 105 can be cleaned to improve its cleaning efficiency.

[0043] Among them, the driving component includes a driving motor 202 fixedly connected to the inside of the bracket 101, and its output end is fixedly connected to an active rod 203, and the outer surface of the active rod 203 is symmetrically rotated along its center and connected to multiple transmission rollers 204, and the inner wall of the bracket 101 is fixedly connected to a diverter plate 404, and one end of the rust removal cleaning cylinder 200 is connected to a swivel 409 that penetrates the diverter plate 404, and the swivel 409 extends to the inside of the bracket 101 and is fixedly connected to a lever 201, and multiple transmission rollers 204 can collide with the lever 201. The power of the rust removal cleaning cylinder 200 comes from the driving motor 202. Through the combination of the active rod 203 and the transmission roller 204, the rust removal cleaning cylinder can swing left and right, and the rust removal work can be completed efficiently. At the same time, the precise meshing of the driving gear 205 and the driven gear 305 ensures the smooth operation of the entire system. In the hot-dip galvanized steel plate production line, this technical solution significantly improves production efficiency and galvanizing quality.

[0044] See also Figure 6 , Figure 7 as well as Figure 8 , and also includes a degreasing spray shell 300, which is connected to one side of the rust removal cleaning cylinder 200 and is used to spray an organic solution to degrease the surface of the steel plate material 105. A liquid storage chamber 301 containing a large amount of organic solution is arranged below the degreasing spray shell 300. The liquid storage chamber 301 is connected to the degreasing spray shell 300 through a pipeline to ensure a continuous supply of organic solution. The degreasing spray shell 300 adopts a high-efficiency atomization technology to evenly cover the surface of the hot-dip galvanized steel plate, further improving the degreasing efficiency and contributing to the adhesion and uniformity of the subsequent galvanized layer.

[0045] Among them, the bottom of the liquid storage chamber 301 is fixedly connected to an infusion pump 302 for extracting the organic solution in the liquid storage chamber 301, and the output end of the infusion pump 302 is fixedly connected to a conduit 306, the top of the degreasing spray shell 300 is connected to an infusion tube 304 connected to the conduit 306, and the inside of the infusion tube 304 is rotatably connected to a lifting impeller 307, and a driven gear 305 fixedly connected to the lifting impeller 307 is provided on one side of the infusion tube 304, and one end of the active rod 203 is fixedly connected to a driving gear 205 meshing with the driven gear 305, so as to realize the circulation of the organic solution inside the liquid storage chamber 301. A wiping plate 401 located on the surface of the steel plate material 105 is fixedly connected to the top of the liquid storage chamber 301, a filter screen 303 for blocking impurities is fixedly connected to the interior of the liquid storage chamber 301, and a return plate 402 is fixedly connected to one side of the wiping plate 401. By setting a lifting impeller 307, the influence of gravity on the organic solution can be overcome, thereby improving the uniform flow direction of the solution, so that both degreasing spray shells 300 obtain adapted solutions.

[0046] Specifically, first, the driving motor 202 is started to drive the active rod 203 to rotate, thereby driving the multiple transmission rollers 204 installed on its outer surface to perform circular motion. At this time, the transmission rollers 204 will continuously push the lever 201 to swing, thereby driving the rust removal cleaning cylinder 200 to rotate back and forth to remove rust from the surface of the steel plate material 105. At the same time, when the rust removal cleaning cylinder 200 starts to operate, the infusion pump 302 is also started to extract organic solution from the liquid storage chamber 301, and the organic solution is transported to the inside of the infusion pipe 304 through the confluence pipe 306 and poured into the inside of the degreasing spray shell 300. Finally, the organic solution The solution is sprayed onto the surface of the steel plate material 105 for degreasing treatment. Subsequently, the wiping plate 401 wipes the surface of the cleaned steel plate material 105, so that the excess organic solution is intercepted and transported to the filter 303 through the reflux plate 402 for filtration. When the active rod 203 rotates, it will drive the active gear 205 to rotate together, thereby engaging with the driven gear 305 to drive the lifting impeller 307 in the infusion tube 304 to rotate, thereby pushing part of the organic solution into the top of the infusion tube 304 to overcome the influence of gravity, so that the organic solution always maintains a uniform flow during the spraying process, further optimizing the degreasing effect. In addition, the wiping action of the wiping plate 401 cooperates with the filtering function of the filter 303 to effectively ensure the cleanliness of the solution and provide a stable quality guarantee for the surface treatment of hot-dip galvanized steel plates.

[0047] In summary, the driving motor 202 drives the active rod 203 to rotate, and then drives the transmission roller 204 to push the lever 201 to swing, so that the rust removal cleaning cylinder 200 can swing left and right, and the two sides of the steel plate material 105 are dynamically and comprehensively rust-removed and cleaned, which significantly improves the rust removal efficiency and cleaning quality. The combination of the infusion pump 302, the confluence pipe 306, the infusion pipe 304 and the lifting impeller 307 realizes the circulation of the organic solution inside the liquid storage chamber 301. This design not only saves resources, but also ensures that the degreasing spray shell 300 can continuously obtain sufficient supply of organic solution to maintain a stable degreasing effect.

[0048] Example 2: Please refer to Figure 8 , Fig. 9 as well as Fig.10 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a plating bath device for hot-dip galvanized steel plate production, further comprising an air pump 400, which is arranged on the top of the bracket 101 for conveying fluid, and is further provided with a diverter assembly that can divert the fluid to the rust removal cleaning cylinder 200 and the wiping plate 401, the diverter assembly comprises a return plate 402 connected to the input end of the air pump 400, the output end of the air pump 400 is fixedly connected to a delivery pipe 407, the interior of the diverter plate 404 is fixedly connected to a diverter ring 408 connected to the delivery pipe 407, the inner wall of the diverter ring 408 is provided with a plurality of liquid passing grooves 412, one end of the rust removal cleaning cylinder 200 passes through the diverter ring 408 and is fixedly connected to a rotating ring 408 rotatably connected thereto 09, the outer surface of the rotating ring 409 is evenly provided with a plurality of overlapping grooves 411 adapted to the liquid-passing grooves 412, and one side of the diverter ring 408 is connected to an exhaust pipe 410, which guides the fluid out of the diverter plate 404 and is connected to an air supply pipe 403, which is connected to the wiping plate 401, and a plurality of air holes are provided on the side of the wiping plate 401 close to the degreasing spray shell 300. By setting the diverter component, the fluid distribution efficiency in the surface treatment process of the hot-dip galvanized steel plate is further improved, thereby realizing the distribution and utilization of gas and hydrochloric acid, and effectively avoiding the waste of resources. At the same time, the conveying capacity of the delivery pipe 407 is combined with the diverter effect of the diverter ring 408 to ensure the processing speed and quality of the fluid on the surface of the hot-dip galvanized steel plate. The production efficiency and the stability of product quality are greatly improved.

[0049] Among them, see Fig.11 , Fig.12 as well as Fig.13A liquid shell 406 is fixedly connected to the top of the bracket 101, and a piston plate 413 adapted thereto is arranged inside the liquid shell 406. The top of the liquid shell 406 is communicated with the air connecting pipe 405. A plurality of gas cylinders 418 are fixedly connected to the inside of the liquid shell 406, and a one-way gas outlet valve 419 is installed on the top of each of the plurality of gas cylinders 418 for conveying the internal gas to the liquid shell 406. By setting the one-way gas outlet valve 419, one-way gas delivery can be achieved, so that the gas in the gas cylinder 418 enters the liquid shell 406 through the one-way gas outlet valve 419, while the gas in the liquid shell 406 cannot enter the gas cylinder 418 through the one-way gas outlet valve 419, thereby achieving one-way gas delivery.

[0050] Furthermore, the inside of the bracket 101 is rotatably connected to an extension rod 308 connected to the lifting impeller 307, and the outer surface of the extension rod 308 is evenly fixedly connected to a plurality of elliptical plates 309, and the bottom of the liquid shell 406 is slidably connected to a plurality of push piston rods 414 whose piston ends are adapted to the gas cylinder 418, and the bottoms of the plurality of push piston rods 414 are rotatably connected to a ball 415 adapted to the elliptical plate 309, and the inside of the push piston rod 414 is fixedly connected to a one-way valve 416 for external gas to enter the inside thereof, and the outer surface of the push piston rod 414 is sleeved with a return spring 416 for its own reset. 17. The elliptical plate 309 rotates along with the rotation of the extension rod 308 to continuously drive the air push piston rod 414 to move upward. In the process of driving the air push piston rod 414 to move upward, the fluid cooperates with the liquid groove 412 and the overlap groove 411 to ensure the effective distribution of gas and hydrochloric acid, thereby optimizing the hot-dip galvanizing process. At the same time, the one-way valve 416 can introduce external gas into the interior of the gas cylinder 418. The flow of gas will ensure that a large amount of organic solution adheres to the surface of the steel plate material 105, and can eventually reflux through the reflux plate 402, which can effectively improve the efficiency of flow resistance under the gas blown out by the wiping plate 401.

[0051] It is worth mentioning that the application of the diverter component cooperates with the driving component. Under the action of the driving component, the rust removal cleaning cylinder 200 will swing back and forth, which makes the rotating ring 409 slide back and forth in the diverter ring 408. Only when the nozzle of the rust removal cleaning cylinder 200 is facing the steel plate material 105, its overlapping groove 411 coincides with the liquid passing groove 412. In this state, the piston plate 413 can be lifted at the same time to transport hydrochloric acid into the empty pipe 405, so that the hydrochloric acid enters the interior of the rust removal cleaning cylinder 200 and is sprayed onto the surface of the steel plate material 105, cooperating with the brush body to improve its rust removal efficiency. At the same time, a small amount of hydrochloric acid will not remain on the surface of the steel plate material 105 due to the combination of the brush body at the edge of the steel plate material 105, and will not affect its subsequent degreasing work.

[0052] Specifically, the pneumatic pump 400 is turned on and the operation of the pneumatic pump 400 will draw fluid from the empty pipe 405. When the lifting impeller 307 rotates, the extension rod 308 will be driven to rotate with it and drive the multiple elliptical plates 309 to rotate. At this time, it will continuously resist the ball 415 and drive the push piston rod 414 to continuously move up and down, thereby pushing the gas in the air cylinder 418 into the interior of the liquid shell 406 through the one-way air outlet valve 419, thereby pushing the piston plate 413 to move upward and squeeze out the hydrochloric acid, so that part of the hydrochloric acid enters the interior of the empty pipe 405 and is transported by the pneumatic pump 400. At the same time, with the cooperation of the one-way valve 416 and the one-way air outlet valve 419, external air enters the interior of the push piston rod 414 to replenish the gas in the air cylinder 418, and the excess gas in the air cylinder 418 will be discharged to the interior of the liquid shell 406 through the one-way air outlet valve 419. , thereby completing the unidirectional movement of the piston plate 413, which makes the pneumatic pump 400 switch back and forth between delivering hydrochloric acid and gas, and when the pneumatic pump 400 delivers gas, the rust removal cleaning cylinder 200 will drive the swivel 409 to swing, so that the overlap groove 411 and the liquid-passing groove 412 are misaligned, so that the incoming gas is guided to the inside of the exhaust pipe 410 when entering the diverter ring 408 through the delivery pipe 407, and then sprayed out through the wiping plate 401, further improving its efficiency in blocking liquid and refluxing more organic solution, and when the hydrochloric acid is delivered, the rust removal cleaning cylinder 200 is swung at an angle whose nozzle is just above the steel plate material 105, at this time The overlap groove 411 and the liquid-passing groove 412 overlap, so that the liquid enters the inside of the swivel 409 and enters the inside of the rust removal cleaning cylinder 200, and finally sprays onto the surface of the steel plate material 105 to improve its rust removal efficiency.

[0053] In summary, the precise distribution of fluids such as hydrochloric acid and gas is achieved through the cooperation of the liquid-passing groove 412 in the diverter ring 408 and the overlap groove 411 on the rotating ring 409. When the rust removal cleaning cylinder 200 needs to spray hydrochloric acid, the overlap groove 411 overlaps with the liquid-passing groove 412, and the hydrochloric acid is accurately delivered to the rust removal cleaning cylinder 200; and when blowing is required, the overlap groove 411 and the liquid-passing groove 412 are misaligned, and the gas is guided to the exhaust pipe 410 and delivered to the wiping plate 401 through the air pipe 403, achieving efficient use of the fluid. The pneumatic pump 400 can flexibly switch between delivering hydrochloric acid and gas according to demand, which not only meets the needs of rust removal and cleaning, but also improves the efficiency of blocking liquid through blowing, and refluxes more effectively. The machine solution realizes the maximum utilization of resources. The rotation of the lifting impeller 307 drives the elliptical plate 309 to rotate through the extension rod 308, thereby pushing the push piston rod 414 to move up and down, providing gas to the gas cylinder 418, realizing the conversion of mechanical energy and gas pressure, and providing a power source for the entire system. The one-way valve 416 allows external gas to enter the push piston rod 414, and the one-way outlet valve 419 ensures that the gas can only flow from the gas cylinder 418 to the liquid shell 406, realizing the one-way flow of gas and ensuring the stability and efficiency of the system.

[0054] Example 3: Please refer to Figures 1 to 13 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a coating bath method for producing hot-dip galvanized steel sheets, comprising the following steps:

[0055] S1. When in use, the steel plate material 105 is first pulled through the rust removal cleaning cylinder 200, the degreasing spray shell 300 and the dryer 107, and then sunk into the interior of the plating bath pot 100 and connected to another winding structure through the guide roller 102 in the pot;

[0056] S2. When the steel plate material 105 needs to be pre-treated and cleaned, the driving motor 202 is first turned on to drive the active rod 203 to rotate so that the multiple transmission rollers 204 connected to its outer surface follow it to make a circular motion. At this time, the transmission rollers 204 will continuously push the lever 201 to swing, thereby driving the rust removal cleaning cylinder 200 to rotate back and forth to remove rust from the surface of the steel plate material 105;

[0057] S3, when the rust removal cleaning cylinder 200 starts to move, the infusion pump 302 is started at the same time, the pump draws the organic solution from the liquid storage chamber 301, transports it to the infusion pipe 304 through the confluence pipe 306, and then pours it into the degreasing spray shell 300, and finally sprays it on the surface of the steel plate material 105 for degreasing treatment. Subsequently, the wiping plate 401 is used to clean the surface of the steel plate material 105, and the excess organic solution is intercepted and guided to the filter screen 303 for filtration through the reflux plate 402. When the active rod 203 rotates, it will drive the active gear 205 to rotate together, thereby meshing with the driven gear 305 to drive the lifting impeller 307 in the infusion pipe 304 to rotate, thereby pushing part of the organic solution into the top of the infusion pipe 304 to overcome the influence of gravity;

[0058] S4. At the same time, the pneumatic pump 400 is turned on. The pneumatic pump 400 will draw fluid from the hollow tube 405 when it is running. When the lifting impeller 307 rotates, the extension rod 308 will be driven to rotate with it, thereby driving the multiple elliptical plates 309 to rotate. At this time, it will continuously collide with the ball 415 to drive the air-pushing piston rod 414 to continuously move up and down, thereby pushing the gas in the air cylinder 418 into the liquid shell 406 through the one-way air outlet valve 419, thereby pushing the piston plate 413 to move upward to squeeze out the hydrochloric acid. Therefore, part of the hydrochloric acid is sent into the hollow tube 405 and transported by the pneumatic pump 400. At the same time, the one-way valve 416 and the one-way air outlet valve 419 work together to allow external air to enter the push piston rod 414 to replenish the gas in the gas cylinder 418, and the excess gas in the gas cylinder 418 will be discharged to the inside of the liquid shell 406 through the one-way air outlet valve 419, thereby completing the one-way movement of the piston plate 413, which makes the pneumatic pump 400 switch back and forth between delivering hydrochloric acid and gas. When the pneumatic pump 400 delivers gas, the rust removal cleaning cylinder 200 will drive the swivel 409 to swing, so that the overlap groove 411 and the liquid passing groove 412 are misaligned, so that the gas entering the liquid passing groove 412 is not in the same position. When entering the diverter ring 408 through the delivery pipe 407, it is guided to the inside of the exhaust pipe 410, and then sprayed out through the wiping plate 401, further improving its resistance to effectively improve the liquid blocking efficiency and ensure the reflux of more organic solution. When transporting hydrochloric acid, by adjusting the swing angle of the rust removal cleaning cylinder 200, its nozzle is accurately aimed at the top of the steel plate material 105. At this time, the overlapping groove 411 and the liquid passing groove 412 are precisely overlapped, and the liquid is able to smoothly enter the inside of the rotating ring 409, and then flow into the rust removal cleaning cylinder 200, and finally sprayed onto the surface of the steel plate material 105 to improve its rust removal efficiency.
