Description

Technical Field

[0001] This invention relates to the field of metal surface treatment technology, and more specifically, to a water washing tank and production line for single-piece high-speed hot-dip galvanizing. Background Technology

[0002] Hot-dip galvanizing is a process in which processed steel wire is immersed in molten zinc, coating the wire surface with a layer of zinc. A single-wire high-speed hot-dip galvanizing production line differs from a traditional multi-line production line. During production, this line processes only one wire at a time. This single-wire processing method allows for precise control of process parameters, ensuring that each wire achieves a stable and consistent galvanizing quality, and avoiding the mutual interference problems that can occur in multi-line production.

[0003] Furthermore, the single-line high-speed hot-dip galvanizing production line adopts an integrated water cleaning process, replacing the pickling process of traditional hot-dip galvanizing production lines. Integrated water cleaning involves washing the drawn steel wire semi-finished products in a water washing tank, with no discharge of the cleaning water, which is then recycled. This method effectively removes surface impurities from the steel wire semi-finished products, avoiding the problems of generating large amounts of acid mist, waste acid, and pickling wastewater during the pickling process, thereby reducing environmental pollution and lowering environmental protection costs.

[0004] In the specific operation, the drawn steel wire is first cleaned of dust by a dust removal device, and then washed in a water washing tank. The water washing tank mainly cleans the steel wire through the scouring action of water flow. During the washing process, the cleaning water flows continuously under the action of the circulation system, forming a water flow with a certain speed and pressure. This water flow directly impacts the surface of the steel wire, peeling off impurities such as metal fragments and particles remaining after the drawing process. This scouring action can effectively remove most visible impurities, providing a cleaner surface for subsequent fluxing and galvanizing processes, and enhancing the adhesion between the galvanized layer and the steel wire.

[0005] However, for some strongly adhering metal debris and particles, simply relying on circulating water rinsing may not completely remove them. This can affect the adhesion of the subsequent galvanized layer, leading to product quality defects such as localized peeling and blistering of the galvanized layer. Therefore, we propose a water washing tank and production line for single-row high-speed hot-dip galvanizing. Summary of the Invention

[0017] A production line comprising a water washing tank for single-row high-speed hot-dip galvanizing, as described above.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. The washing tank of this invention not only relies on the circulating water flow in the first and second circulating water tanks to remove impurities from the surface of the steel wire, but also rinses the surface of the steel wire through the circulating flushing chamber. Furthermore, the impurity removal components scrape and rub the outer surface of the steel wire, effectively removing strongly adhering metal particles. The combination of multiple cleaning and impurity removal methods solves the problem that conventional rinsing, which involves completely immersing the steel wire in water, is insufficient to remove strongly adhering metal debris and particles from the steel wire surface by simply relying on circulating water flow.

[0019] 2. This invention changes the traditional straight-line washing path by designing the steel wire's washing path as an undulating, zigzag shape. This design enables a bottom-immersion and top-rinse washing method for the steel wire. At the lower end of the undulating, zigzag shape, the steel wire is immersed in the washing water, and impurities adhering to the surface are removed by circulating water. At the higher end, the steel wire is rinsed by high-pressure water flow inside the circulating flushing chamber, which can remove strongly adhered metal debris or particles from the surface. At the same time, the undulating, zigzag washing path can change the movement state of the steel wire, causing the surface of the steel wire to bend. Impurities are subjected to stretching and compression forces, which break their adhesion to the steel wire surface, making them easier to detach.

[0020] 3. This invention also utilizes a compensated scraping assembly to automatically replace the semi-circular grinding head by employing constant force. When the semi-circular grinding head is in its complete state, its rotation path intersects with the steel wire on the inclined path section, removing impurities through friction with the steel wire. When the semi-circular grinding head is severely worn, its rotation path separates from the steel wire, and the rotation trend of the driven gear drives the circular base plate to rotate, carrying the worn semi-circular grinding head away from the workstation, allowing another complete semi-circular grinding head to enter the workstation. This achieves real-time monitoring and automatic replacement of the semi-circular grinding head's usage, ensuring the continuous and stable operation of the scraping work.

[0021] 4. This invention also designs a waterwheel with a special structure, enabling the water tank of the waterwheel to continuously receive the cleaning water discharged from the circulating flushing chamber. Through the designed drain and overflow outlets, the cleaning water in the water tank is continuously discharged from the drain outlet, and the water at the top is discharged from the overflow outlet, ensuring a constant water volume in the water tank. This constant water volume generates a constant gravitational force. The waterwheel will generate a torque due to the gravitational imbalance, which causes the driving gear coaxially connected to the waterwheel to rotate and maintain this rotational tendency. The rotational tendency of the driving gear is transmitted to the driven gear through the transmission gear, thus ensuring that the circular base plate always has a driving force to rotate. By ensuring that the constant gravity generated by the constant water volume in the water tank is less than the reaction force of the steel wire on the semi-circular grinding head, the semi-circular grinding head can stably rub against the steel wire in its complete state. This avoids the instability of the rotational force, which could easily cause the semi-circular grinding head to push the steel wire into elastic deformation, causing the semi-circular grinding head to pass over the steel wire and lose its frictional effect.

[0022] 5. The present invention also provides a larger discharge diameter by designing the overflow port as a long strip-shaped groove structure, which enables the cleaning water reaching the overflow port to be discharged quickly, ensuring that the water storage in the water tank remains constant. This avoids the overflow port draining water slowly, which could easily cause changes in the water storage in the water tank and thus affect the working state of the semi-circular grinding head.

[0023] 6. This invention arranges the impurity removal component between the first circulating water tank and the circulating flushing chamber. Before the steel wire is scraped, it is pre-cleaned by the first circulating water tank. When the steel wire enters the downward scraping component and the compensating scraping component of the impurity removal component, cold water adheres to the surface of the steel wire. As the steel wire is continuously transported, the cold water is continuously brought into the block grinding head and the semi-circular grinding head, achieving the effect of cooling the block grinding head and the semi-circular grinding head. This solves the problem that the block grinding head and the semi-circular grinding head are prone to generating heat due to friction with metal debris on the surface of the steel wire and the steel wire itself. High temperature may cause changes in the performance of the block grinding head and the semi-circular grinding head, such as reduced hardness and wear resistance. Attached Figure Description

Detailed Implementation

[0026] To address the related technical issues, embodiments of the present invention provide a water washing tank and production line for single-piece high-speed hot-dip galvanizing.

[0027] like Figures 1 to 13 As shown, the present invention provides a water washing tank for single high-speed hot-dip galvanizing. The water washing tank is set between the wire drawing machine and the wiping equipment. The steel wire semi-finished product drawn by the drawing machine is washed with water to further remove surface impurities of the steel wire semi-finished product.

[0028] The washing tank includes a first circulating water tank 1, a circulating flushing chamber 2, a second circulating water tank 3, and a reclaimed water tank 4. The reclaimed water tank 4 is arranged between the first circulating water tank 1 and the second circulating water tank 3, and the circulating flushing chamber 2 is arranged above the reclaimed water tank 4. Circulating water flows are arranged inside the first circulating water tank 1 and the second circulating water tank 3 to remove impurities from the surface of the steel wire 6. The circulating flushing chamber 2 is used to rinse the surface of the steel wire 6. A filter device is arranged inside the reclaimed water tank 4. The filter device is the prior art of this example and is used to filter the wastewater after rinsing. The reclaimed water tank 4 is used to collect the wastewater discharged from the first circulating water tank 1, the circulating flushing chamber 2, and the second circulating water tank 3, and filter it through the filter device. The filtered water is recycled. A fixing frame 7 is arranged on the top of the reclaimed water tank 4. The fixing frame 7 consists of two symmetrically distributed plate frame structures. Multiple circulating water pumps 8 are installed on the fixing frame 7. The multiple circulating water pumps 8 are used to guide the filtered water in the reclaimed water tank 4 into the first circulating water tank 1, the circulating flushing chamber 2, and the second circulating water tank 3, respectively.

[0029] In some embodiments, the first circulating water tank 1, the circulating flushing chamber 2, the second circulating water tank 3, and the reclaimed water tank 4 are all equipped with protective covers that match their tank dimensions. This effectively reduces the liquid evaporation rate, minimizing material loss and environmental pollution. Simultaneously, the airtight design prevents dust and foreign objects from entering, ensuring the cleanliness of the washing tank interior and thus guaranteeing the accuracy and stability of the washing operation, extending the equipment's lifespan. During equipment operation, opening the protective covers is strictly prohibited, as there is a risk of scalding from hot water.

[0030] Furthermore, the washing tank is fitted with a dust cover and has sealing strips on the edges, forming a solid protective barrier that can resist interference from workshop dust, processing debris, etc., ensuring a clean environment for washing operations and providing reliable protection for efficient equipment operation and stable process flow.

[0031] In an embodiment of the present invention, the steel wire 6 output from the wire drawing machine enters sequentially through the guide wheel into the first circulating water tank 1, the circulating flushing chamber 2, and the second circulating water tank 3. The steel wire 6 output from the second circulating water tank 3 enters the wiping device for wiping. The circulating water in the inner cavities of the first circulating water tank 1 and the second circulating water tank 3 can flow continuously. When the steel wire 6 passes through these two water tanks, the circulating water will carry away impurities on the surface of the steel wire 6. When the steel wire 6 passes through the circulating flushing chamber 2, the circulating flushing chamber 2 will rinse the surface of the steel wire 6, further removing residual impurities on the surface of the steel wire 6 and improving the cleaning effect. The first circulating water tank 1, the circulating flushing chamber 2, and the second circulating water tank 3 make the water washing path of the steel wire 6 undulating and zigzag. The present invention changes the traditional straight water washing path of the steel wire 6, making the water washing of the steel wire 6 more efficient. The path is designed as an undulating, zigzag pattern, enabling a bottom-immersion and top-rinse water washing method for the steel wire 6. Specifically, the lower end of the undulating, zigzag pattern is immersed in the washing water, where circulating water carries away impurities adhering to the surface of the steel wire 6. The upper end of the undulating, zigzag pattern is rinsed by the high-pressure water flow inside the circulating flushing chamber 2, removing strongly adhered metal debris or particles from the surface of the steel wire 6. This multi-method cleaning improves the cleaning effect on the steel wire 6. Furthermore, the undulating, zigzag water washing path alters the movement of the steel wire 6, causing its surface to bend. This further subjectes impurities on the surface of the steel wire 6 to different forms of force, such as stretching and compression. For strongly adhered metal debris or particles, these forces can break the bond between the debris and particles and the surface of the steel wire 6, making them easier to detach.

[0032] In an embodiment of the present invention, a first water inlet is provided on one side wall of the first circulating water tank 1 and a first drain outlet 101 is provided at the lower end of the other side wall; a second water inlet is provided on one side wall of the second circulating water tank 3 and a second drain outlet 301 is provided at the lower end of the other side wall; the first water inlet is connected to the output end of the circulating water pump 8 through a water pipe, and the second drain outlet 301 is connected to the output end of another circulating water pump 8 through another water pipe; the first drain outlet 101 and the second drain outlet 301 are arranged above the reclaimed water tank 4.

[0033] In an embodiment of the present invention, the circulating flushing chamber 2 is fixedly arranged on the inner wall of the fixed frame 7, ensuring its stable position in the entire washing tank system; a baffle 201 is detachably connected to the side wall of the circulating flushing chamber 2 by bolts, which facilitates opening the baffle 201 for internal maintenance, cleaning, or inspection when needed; the bottom of the circulating flushing chamber 2 is set as an inclined surface, and a drainage channel 202 is formed at the lower end of the inclined surface, so that the wastewater after rinsing the steel wire 6 can flow naturally to the lower end of the inclined surface, be discharged from the circulating flushing chamber 2 through the drainage channel 202, and enter the recycled water tank 4 for subsequent filtration and recycling; a connecting hole is opened on the side wall of the baffle 201, and a connecting hole of the same structure is opened on the other side wall of the circulating flushing chamber 2, the connecting hole is used for the steel wire 6 to pass through, and four support rods 2 are arranged in a ring array inside the circulating flushing chamber 2. 03. The support rod 203 has multiple arc-shaped clips 204 connected to its side wall. The arc-shaped clips 204 are semi-circular plate structures with elastic fastening, which can firmly clamp the water spray pipe 205, while allowing the water spray pipe 205 to be adjusted to a certain extent. The inner cavity of the circulating flushing chamber 2 is also equipped with four water spray pipes 205. The water spray pipes 205 are movably inserted into the arc-shaped clips 204. Every two water spray pipes 205 are connected by an arc-shaped pipe 206. One of the arc-shaped pipes 206 has an outer pipe 207 connected to its side wall. The outer pipe 207 passes through the top of the circulating flushing chamber 2 and is used to receive the cleaning water delivered by the circulating water pump 8. The output end of the water spray pipe 205 is connected to multiple nozzles 208. The nozzles 208 of the four water spray pipes 205 can respectively rinse the outer wall of the steel wire 6 at different angles. After the cleaning water enters the circulating flushing chamber 2 through the external pipe 207, it is distributed among the four spray pipes 205 through the arc-shaped pipe 206, so that the cleaning water can be evenly distributed to each spray pipe 205. Since the four spray pipes 205 are arranged in a ring array and the nozzles 208 are distributed on the spray pipes 205, the steel wire 6 can be rinsed in all directions, ensuring that all parts of the surface of the steel wire 6 can be cleaned and effectively removing impurities from the surface of the steel wire 6.

[0034] In an embodiment of the present invention, a cleaning component 5 is further arranged between the first circulating water tank 1 and the circulating flushing chamber 2. The cleaning component 5 can scrape and rub the outer surface of the steel wire 6 to remove the metal particles attached to the outer surface of the steel wire 6. The cleaning component 5 includes a downward scraping component 51 and a compensating scraping component 52. The compensating scraping component 52 includes an active rotating component 521 with a constant driving force and a unidirectional rotating driven component 522. The active rotating component 521 can apply a continuous rotational driving force to the driven rotating component 522, giving the driven rotating component 522 a rotational tendency. By designing the cleaning component 5 as a downward scraping component 51 and a compensating scraping component 52, the present invention can treat the surface of the steel wire from different angles, enhance the cleaning effect, effectively remove the strongly attached metal particles on the surface of the steel wire 6, and reduce the burden on subsequent cleaning processes.

[0035] In an embodiment of the present invention, the downward-pressing scraping assembly 51 includes a plurality of guide posts 5101 connected to the top of the first circulating water tank 1. A counterweight 5102 is slidably sleeved on the guide posts 5101. A block-shaped grinding head 5103 is connected to the bottom of the counterweight 5102. The bottom of the block-shaped grinding head 5103 is set as an inclined surface to match the transmission path of the steel wire 6. A first grinding groove 5104 is opened at the bottom of the block-shaped grinding head 5103. The first grinding groove 5104 is used to scrape the upper half of the outer wall of the steel wire 6 to remove the attached metal particles. Due to the gravity of the counterweight 5102 itself, it will slide downward along the guide posts 5101. The guide post 5101 restricts and guides the movement direction of the counterweight 5102, allowing it to move only vertically. This ensures that the block grinding head 5103 can stably scrape the steel wire 6, preventing deviation during the scraping process. The block grinding head 5103, connected to the bottom of the counterweight 5102, moves closer to the steel wire 6 as the counterweight 5102 is pressed down. The bottom of the block grinding head 5103 is designed with an inclined surface to match the transmission path of the steel wire 6. This design allows the block grinding head 5103 to better conform to the surface of the steel wire 6 when in contact, ensuring that the scraping force is evenly distributed on the steel wire 6. Meanwhile, the first grinding groove 5104 at the bottom of the block grinding head 5103 is shaped and positioned to match the upper half of the outer wall of the steel wire 6. When the block grinding head 5103 presses down and contacts the steel wire 6, the first grinding groove 5104 is in close contact with the upper half of the outer wall of the steel wire 6. As the steel wire 6 is conveyed in the production line, it continuously moves relative to the block grinding head 5103. Friction is generated between the groove wall of the first grinding groove 5104 and the upper half of the outer wall of the steel wire 6. Under the action of friction, the metal particles attached to the upper half of the outer wall of the steel wire 6 are scraped off. Compared with simply relying on water flow to wash, this scraping method can more effectively remove metal particles with strong adhesion, further improving the cleanliness of the surface of the steel wire 6, providing a better foundation for subsequent processes such as fluxing and galvanizing, enhancing the adhesion between the galvanized layer and the steel wire, and improving product quality.

[0036] In an embodiment of the present invention, the compensating scraping assembly 52 further includes a transmission gear 523 rotatably arranged on the inner sidewall of the fixed frame 7, and the active rotating assembly 521 and the driven rotating assembly 522 are respectively rotatably arranged on the inner sidewall of the fixed frame 7; wherein, the active rotating assembly 521 is arranged below the circulating punch chamber 2, the transmission gear 523 is arranged between the active rotating assembly 521 and the driven rotating assembly 522, and the driven rotating assembly 522 is arranged below the steel wire 6; the active rotating assembly 521 includes an active gear 52101, which meshes with the transmission gear 523; the driven rotating assembly 522 includes a driven gear 52201, which meshes with the transmission gear 523.

[0037] In an embodiment of the present invention, the active rotating component 521 further includes a water wheel 52102 coaxially connected to the active gear 52101; the water wheel 52102 is composed of two ring plates 521021 and multiple guide plates 521022, the multiple guide plates 521022 are arranged in a ring at equal intervals between the two ring plates 521021, and a water storage tank 521023 is formed between every two guide plates 521022, there are eight water storage tanks 521023, the cleaning water discharged from the drainage channel 202 is guided into the water storage tank 521023 through the guide plates 521022, and the water is driven by the gravity generated by the water storage tank 521023 containing the cleaning water. The driving gear 52101 generates a rotational tendency; the side wall of the ring plate 521021 has multiple drain ports 521024 and multiple overflow ports 521025, which are arranged in a ring at equal intervals; the drain ports 521024 are connected to the lower end of the inner cavity of the water storage tank 521023, and the overflow ports 521025 are connected to the upper end of the inner cavity of the water storage tank 521023; the drain ports 521024 are circular holes, and the overflow ports 521025 are elongated slots, used to drain water overflowing from the water storage tank 521023, so that the water volume inside the water storage tank 521023 remains constant. The drainage channel 202 on the inclined surface at the bottom of the circulating flushing chamber 2 discharges cleaning water, which is received by the water wheel 52102 in the active rotating component 521. The guide plate 521022 of the water turbine 52102 directs the cleaning water into the water storage tank 521023. The cleaning water in the water storage tank 521023 is continuously discharged from the drain outlet 521024. As the drainage channel 202 continuously discharges cleaning water, the water volume in the water storage tank 521023 gradually increases until the water level reaches the overflow outlet 521025. Since the overflow outlet 521025 is designed as a long, narrow slot structure, it can quickly discharge the cleaning water that reaches the overflow outlet 521025, thus allowing the water storage tank 521023 to flow smoothly. The water volume in the storage tank 521023 is kept constant, which further makes the gravity generated by the constant water volume constant. By controlling the water volume in the storage tank 521023, the constant gravity is made less than the reaction force generated by the steel wire 6 and the semi-circular grinding head 52205. The water wheel 52102 will generate a torque due to the gravity imbalance. This torque causes the drive gear 52101, which is coaxially connected to the water wheel 52102, to have a rotational tendency and can maintain this rotational tendency. The rotational tendency of the drive gear 52101 will be transmitted to the driven gear 52201 through the transmission gear 523.

[0038] In an embodiment of the present invention, the driven rotation assembly 522 further includes a circular base plate 52202 coaxially connected to the driven gear 52201 and a one-way bearing 52203. The one-way bearing 52203 is prior art and will not be described in detail. A circular hole is provided on the side wall of the fixing frame 7. The outer ring of the one-way bearing 52203 is fixedly connected to the inner side wall of the circular hole in the fixing frame 7, and the inner ring of the one-way bearing 52203 is coaxially connected to the driven gear 52201. This ensures that the driven gear 52201 can only rotate in one direction, and the circular base plate 52202 coaxially connected to the driven gear 52201 can also only rotate in one direction. The rotational tendency transmitted from the driving gear 52101 to the driven gear 52201 will cause the circular base plate 52202 coaxially connected to the driven gear 52201 to rotate. Furthermore, multiple grinding head supports 52204 are fixedly connected to the outer circumference of the circular substrate 52202, and the multiple grinding head supports 52204 are arranged in a ring array; a semi-circular grinding head 52205 is detachably connected to the grinding head support 52204. The semi-circular grinding head 52205 is a semi-cylindrical block structure, and a second grinding groove 52206 is opened on the arc surface of the semi-circular grinding head 52205. The semi-circular grinding head 52205 is arranged below the steel wire 6 in the inclined path section, and one of the semi-circular grinding heads is positioned below the steel wire 6 in the inclined path section. The second grinding groove 52206 of the circular grinding head 52205 forms contact friction with the side wall of the steel wire 6, which is used to scrape the lower half of the outer side wall of the steel wire 6 to remove the attached metal particles. When the semi-circular grinding head 52205 is in the complete state, the rotation path of the semi-circular grinding head 52205 intersects with the inclined path section of the steel wire 6. When the semi-circular grinding head 52205 is in a severely worn state, the rotation path of the semi-circular grinding head 52205 separates from the inclined path section of the steel wire 6. In this invention, when the semi-circular grinding head 52205 is in its complete state, its rotation path intersects with the steel wire 6 in the inclined path section, making it difficult for the driven gear 52201 to rotate and cause the circular substrate 52202 to rotate. At this time, the second grinding groove 52206 of the semi-circular grinding head 52205 comes into contact with the sidewall of the steel wire 6. By conveying the steel wire 6 forward, friction is formed between the steel wire 6 and the second grinding groove 52206, which can scrape away the metal debris and particles strongly attached to the surface of the steel wire 6. As the usage time increases, the semi-circular grinding head 52205 will gradually wear down. When the wear is severe... When the load is heavy, the rotation path of the semi-circular grinding head 52205 is separated from the steel wire 6. At this time, the rotation trend of the driven gear 52201 drives the circular base plate 52202 to rotate. The circular base plate 52202 carries the worn semi-circular grinding head 52205 away from the work station, and another complete semi-circular grinding head 52205 enters the work station to work. This invention can use the rotation trend generated by the water wheel 52102 to monitor the usage of the semi-circular grinding head 52205 in real time, ensuring that the semi-circular grinding head 52205 can always work normally and always maintain contact with the steel wire 6.

[0039] In an embodiment of the present invention, a slot 52207 is provided on the side wall of the grinding head support 52204, and an insert plate 52208 is connected to the bottom of the semi-circular grinding head 52205. The insert plate 52208 is movably inserted into the slot 52207. The grinding head support 52204 has two insertion holes 1 from top to bottom, and the insert plate 52208 has two insertion holes 2 from top to bottom. The insertion holes 1 and 2 are holes of the same diameter. A cross plate 52209 is movably arranged in the bottom cavity of the grinding head support 52204. The bottom of the cross plate 52209 is connected to the outer circumference of the circular base plate 52202 by multiple springs 52210. Two insertion posts 52211 are connected to the top of the cross plate 52209. When the insert plate 52208 is inserted into the slot 52207, the insertion posts 52211 are used to insert into the insertion hole 1 and extend into the insertion hole 2 to form a locking effect. When the semi-circular grinding head 52205 needs to be replaced during downtime maintenance, the operator only needs to apply a downward pressure to the cross plate 52209 to overcome the elastic force of the spring 52210, so that the insertion post 52211 is removed from the insertion hole one and insertion hole two, and the insertion plate 52208 is pulled out from the slot 52207, thereby completing the disassembly of the semi-circular grinding head 52205 and facilitating the replacement of the new semi-circular grinding head 52205.

[0040] Working principle: During use, the drawn steel wire 6 enters the first circulating water tank 1, the circulating flushing chamber 2, and the second circulating water tank 3 of the washing tank sequentially through the guide wheel. When the steel wire 6 enters the first circulating water tank 1, the circulating water in the first circulating water tank 1 flows continuously, carrying away most of the impurities on the surface of the steel wire 6. When the steel wire 6 passes through the circulating flushing chamber 2, multiple nozzles 208 in the circulating flushing chamber 2 rinse the surface of the steel wire 6 from different angles, further removing the impurities remaining on the surface of the steel wire 6. Then the steel wire enters the second circulating water tank 3, where the circulating water flows continuously, carrying away any impurities that may remain on the surface of the steel wire 6 again. During this period, the water washing path of the steel wire 6 is undulating and zigzag-shaped. This design realizes the water washing method of immersion and rinsing of the steel wire 6 from below. During this period, when the steel wire 6 passes through the impurity removal component 5 between the first circulating water tank 1 and the circulating flushing chamber 2, the downward pressure scraping component 51 passes through the block grinding head 5103. The grinding head 52205 makes close contact with the outer wall of the upper half of the steel wire 6 and generates friction, scraping off the metal particles attached to the outer wall of the upper half of the steel wire 6. The compensation grinding assembly 52 performs the grinding work by friction between the semi-circular grinding head 52205 and the steel wire 6, scraping off the metal particles strongly attached to the outer wall of the lower half of the steel wire 6. When the semi-circular grinding head 52205 is severely worn, its rotation path separates from the steel wire 6. The rotation trend of the driven gear 52201 drives the circular base plate 52202 to rotate, taking the worn semi-circular grinding head 52205 away from the station. Another complete semi-circular grinding head 52205 enters the station to continue working, realizing real-time monitoring and automatic replacement of the semi-circular grinding head 52205.

[0041] According to another aspect of this application, a production line is provided, comprising the washing tank as described above. The production line includes a wire feeding rack, a sanding cloth belt machine, a wire drawing machine, a dust removal device, a wiping device, a fluxing tank, a drying device, a galvanizing tank, a cooling device, and a wire unloading machine connected in sequence. The washing tank is disposed between the dust removal device and the wiping device.

[0042] Among them, the wire feeding frame, sanding cloth belt machine, wire drawing machine, dust removal equipment, wiping equipment, galvanizing tank, drying equipment, galvanizing tank, cooling equipment and wire dropping machine are all existing technologies in the example, used in the hot-dip galvanizing production line.

[0043] Taking this embodiment as an example, the wire feeding frame feeds the steel wire 6 raw material, which is then ground and rust-removed by a sanding belt machine. The mechanical function of the sanding belt machine is to remove oxide scale and rust. It is used to process high, medium, and low carbon steel wire rods and various alloy wire rods. It can monitor the position of the sanding belt in real time and can stop and alarm when the sanding belt breaks or deviates due to abnormal wear, thereby reducing the generation of defective products and mold wear. The sanding belt machine is equipped with a sanding belt tensioning device, which can display the sanding belt tension and adjust the tension through data to ensure the grinding effect.

[0044] Then, the steel wire 6 raw material is drawn by a wire drawing machine to reduce its diameter and obtain the required size of steel wire 6. The dust removal equipment cleans up the dust generated during the drawing process of steel wire 6. In this embodiment, a cartridge dust collector is used, which can absorb and filter the dust in the air generated during the wire drawing process. The cartridge is made of the most efficient filter material currently available, and its efficiency for dust larger than 0.5 microns is ≥99.5%. Subsequently, the drawn steel wire 6 is washed in a water washing tank to further remove impurities from its surface. After washing, the steel wire 6 is wiped dry by a wiping device, and then coated with a flux evenly in a fluxing tank to prevent rusting, activate the surface of the steel wire 6, and provide good adhesion for subsequent hot-dip galvanizing. The fluxed steel wire 6 is then placed in a drying device to be dried quickly. After drying, the steel wire 6 is immersed in a galvanizing tank for galvanizing, so that a galvanized layer covers the surface of the steel wire 6. The galvanized steel wire 6 is cooled and shaped by a cooling device to prevent the galvanized layer from oxidizing at high temperatures. After galvanizing, the steel wire 6 is wound into coils by a winding machine.

Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
