Description

Technical Field

[0001] This application relates to the field of iron wire galvanizing technology, and in particular to an apparatus for galvanizing rust-proof iron wire. Background Technology

[0002] Zinc plating is a surface treatment technique that involves coating the surface of metals, alloys, or other materials with a layer of zinc for aesthetic purposes, rust prevention, and other functions. An existing patent (publication number: CN209243146U) discloses a galvanizing device for iron wire, including a solution tank with an open top. A support plate is fixedly installed at one end of the top of the solution tank. A hollow sleeve is fixedly connected to the bottom surface of the support plate. A charcoal powder inlet and an iron wire outlet are connected through the surface of the support plate with the sleeve. A cover plate is hinged to the end of the solution tank without the support plate. A flow-blocking plate is hinged to the end of the cover plate near the support plate through an opening and closing mechanism. An iron wire inlet is also provided on the cover plate. A first submerged wheel and a second submerged wheel are also provided inside the solution tank. The second submerged wheel is positioned opposite the iron wire outlet. A stirring mechanism is provided downward on the cover plate. The solution tank is connected to a zinc liquid replenishment mechanism. A drying mechanism and a wire coiling mechanism are also provided on one side of the solution tank. This utility model has the advantages of good wiping effect, high galvanizing quality, and simple structure.

[0003] Although the device in the aforementioned comparative document can achieve the effect of galvanizing, the lack of pretreatment on the surface of the iron wire will affect the bonding strength between the zinc layer and the substrate, and easily lead to blistering and peeling of the coating. In order to solve the above problems, a rust-proof iron wire galvanizing device is proposed. Utility Model Content

[0004] The purpose of this application is to provide a galvanizing device for rust-proof iron wire, which optimizes the galvanizing process and solves the problems mentioned in the background art.

[0005] The rust-proof iron wire galvanizing device provided in this application adopts the following technical solution: A rust-proof iron wire galvanizing device includes a main treatment box and a physical rust removal mechanism. The physical rust removal mechanism includes two supports fixedly connected to the inlet end of the main treatment box. A main steel wire brush roller and an auxiliary steel wire brush roller are respectively installed on the inner wall of the two supports. A servo motor is fixedly connected to the outer surface of the lower support of the two supports. The output shaft end of the servo motor is fixedly connected to the rotating shaft end of the main steel wire brush roller. The interior of the main treatment box is provided with a heat treatment mechanism, an oxygen-free cooling mechanism, a fluxing agent adhesion mechanism, and a galvanizing mechanism. The inner wall of the main treatment box has evenly distributed wire-leading holes, and a high-temperature resistant silicone sealing ring is installed on the inner wall of each wire-leading hole.

[0006] The heat treatment mechanism includes a heat treatment chamber located inside the main treatment chamber. The inner wall of the heat treatment chamber is fitted with uniformly distributed first electric heating tubes. A reducing gas delivery pipe is connected to the top of the heat treatment chamber. The oxygen-free cooling mechanism includes a cooling chamber located inside the main treatment chamber. Multiple rotatable hollow rollers are installed on the inner wall of the cooling chamber. Multiple connecting pipes are installed on the outer surface of the main treatment chamber. The multiple hollow rollers are connected to each other via multiple connecting pipes. An inlet pipe and an outlet pipe are installed on the inner wall of the cooling chamber. The interior of the inlet pipe and the outlet pipe are respectively connected to the hollow rollers on both sides. An inert gas inlet pipe is connected to the top of the cooling chamber.

[0007] By adopting the above technical solution, in the physical rust removal mechanism, the servo motor drives the main wire brush roller to rotate, which, together with the auxiliary wire brush roller, performs friction cleaning on the surface of the iron wire. This effectively removes rust, scale, oil, and other impurities from the iron wire surface, solving the problem in the background technology where insufficient bonding strength between the zinc layer and the substrate, and easy blistering and peeling of the coating, are caused by the lack of pretreatment of the iron wire surface. This provides a clean surface foundation for the subsequent galvanizing process. In the heat treatment mechanism, the first electric heating tube creates a suitable temperature environment in the heat treatment chamber, and the reducing gas introduced through the reducing gas delivery pipe can remove residual rust on the iron wire surface. The trace oxide layer is reduced to further enhance the surface activity of the iron wire and improve the adhesion of the subsequent zinc layer. This makes up for the lack of oxide layer reduction treatment in the existing technology. In the oxygen-free cooling mechanism, the inert gas introduced through the inert gas inlet pipe can form an oxygen-free atmosphere in the cooling chamber, avoiding secondary oxidation of the iron wire when it comes into contact with air during the cooling process. At the same time, the hollow roller achieves circulating cooling through the connecting pipe, water inlet pipe and water outlet pipe, which can quickly reduce the temperature of the iron wire and solve the problem of easy secondary oxidation of the iron wire during the cooling stage in the background technology, ensuring the cleanliness and activity of the iron wire surface.

[0008] Preferably, the interior of the heat treatment chamber is connected to an exhaust pipe, which is installed on the outer surface of the main treatment chamber.

[0009] By adopting the above technical solution, the exhaust pipe can discharge the gas after the reaction in the heat treatment chamber in a timely manner, avoid the accumulation of exhaust gas in the chamber and affect the stability of the reducing atmosphere, ensure that the oxide layer reduction reaction is fully carried out, and further improve the surface treatment quality of iron wire.

[0010] Preferably, the cooling chamber is internally connected to an oxygen venting pipe, which is installed on the outer surface of the main treatment chamber.

[0011] By adopting the above technical solution, the oxygen venting pipe can expel the air initially present in the cooling chamber and any small amount of air that may have seeped in, ensuring that the inert gas fully fills the chamber, enhancing the oxygen-free cooling effect, and fundamentally eliminating the risk of secondary oxidation during iron wire cooling.

[0012] Preferably, the fluxing agent attachment mechanism includes an attachment cavity located inside the main treatment chamber, and a fluxing tank is installed on the inner bottom wall of the attachment cavity.

[0013] By adopting the above technical solution, the fluxing tank in the fluxing agent attachment mechanism can hold the fluxing agent, so that the pre-treated iron wire can fully contact the fluxing agent in the attachment cavity, which helps the subsequent zinc layer to adhere more evenly to the surface of the iron wire. This solves the problem of uneven coating in the existing technology and improves the quality of zinc plating.

[0014] Preferably, a first guide wheel assembly is installed inside the plating tank, and a squeeze roller assembly is installed inside the attachment cavity, with the squeeze roller assembly located above the first guide wheel assembly.

[0015] By adopting the above technical solution, the first guide wheel assembly guides the movement path of the iron wire in the fluxing tank, ensuring that the iron wire is fully immersed in the fluxing agent; the squeeze roller assembly can remove excess fluxing agent from the surface of the iron wire, avoiding excessive fluxing agent from being carried into the subsequent zinc plating mechanism and affecting the purity of the zinc liquid, thus ensuring the fluxing effect and maintaining the stability of the zinc plating environment.

[0016] Preferably, the top of the plating tank is connected to a first injection pipe, and the bottom of the plating tank is connected to a first drain pipe.

[0017] By adopting the above technical solution, the first injection pipe facilitates the replenishment of flux into the fluxing tank, and the first drain pipe facilitates the replacement of waste flux, so that the flux is always kept in good working condition, ensuring stable fluxing effect and improving the ease of operation of the device.

[0018] Preferably, the galvanizing mechanism includes a galvanizing chamber located inside the main processing box, a galvanizing tank installed on the inner bottom wall of the galvanizing chamber, and a second guide wheel assembly and a second electric heating tube installed inside the galvanizing tank, with the second guide wheel assembly located above the second electric heating tube.

[0019] By adopting the above technical solution, in the galvanizing mechanism, the zinc liquid in the galvanizing tank is kept at a suitable temperature under the action of the second electric heating tube, and the second guide wheel assembly guides the iron wire to form a reasonable movement trajectory in the zinc liquid, ensuring that the iron wire surface is evenly covered with a zinc layer, thus solving the problem of poor coating quality in the background technology and enhancing the rust resistance of the iron wire.

[0020] Preferably, the top of the galvanizing tank is connected to a second injection pipe, and the bottom of the galvanizing tank is connected to a second drain pipe.

[0021] By adopting the above technical solution, the second injection pipe facilitates the replenishment of zinc liquid to the galvanizing tank, and the second drain pipe facilitates the discharge of impurities or waste zinc liquid from the tank, which helps maintain the purity and performance stability of the zinc liquid and ensures the consistency of galvanizing quality in mass production.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This rust-proof iron wire galvanizing device effectively removes rust, scale, and oil from the iron wire surface by using a servo motor-driven main wire brush roller in a physical rust removal mechanism, which works in conjunction with an auxiliary wire brush roller. This solves the problem of insufficient bonding strength between the zinc layer and the substrate caused by the lack of pretreatment in existing technologies. The heat treatment mechanism then creates a suitable temperature environment within the heat treatment chamber using a first electric heating tube, which, combined with a reducing gas supply pipe, reduces the residual oxide layer on the iron wire surface, enhancing surface activity. Finally, the oxygen-free cooling mechanism uses an inert gas inlet pipe within the cooling chamber to introduce gas... An oxygen-free atmosphere is created, and the hollow rollers achieve circulating cooling through connecting pipes, inlet pipes, and outlet pipes, preventing secondary oxidation of the iron wire during cooling. The flux attachment mechanism contains the flux in the flux tank, and the squeeze roller assembly removes excess flux, ensuring uniform coating. In the galvanizing mechanism, the second electric heating tube in the galvanizing tank maintains a suitable temperature for the zinc liquid, and the second guide wheel assembly guides the iron wire to form a reasonable trajectory, ensuring uniform zinc coating. At the same time, the high-temperature resistant silicone sealing ring in the wire guide hole maintains the sealing stability of each cavity, significantly improving the overall galvanizing quality and the rust prevention performance of the iron wire.

[0028] Example 2: A galvanizing device for rust-proof iron wire, referring to... Figure 3 , Figure 4 and Figure 5 Based on the same concept as Embodiment 1 above, this embodiment proposes a fluxing agent attachment mechanism 5 including an attachment cavity 501 opened inside the main processing box 1. A fluxing tank 502 is installed on the inner bottom wall of the attachment cavity 501. The fluxing tank 502 in the fluxing agent attachment mechanism 5 can hold the fluxing agent, so that the pre-treated iron wire can fully contact the fluxing agent in the attachment cavity 501, which helps the subsequent zinc layer to adhere more evenly to the surface of the iron wire, solving the problem of uneven coating in the prior art and improving the zinc plating quality. A first guide wheel assembly 503 is installed inside the fluxing tank 502, and a squeeze roller assembly 504 is installed inside the attachment cavity 501. The squeeze roller assembly 504 is located above the first guide wheel assembly 503. The first guide wheel assembly 503 guides the movement path of the iron wire in the fluxing tank 502, ensuring that the iron wire is fully immersed in the flux. The squeeze roller assembly 504 removes excess flux from the surface of the iron wire, preventing excessive flux from being carried into the subsequent zinc plating mechanism 6 and affecting the purity of the zinc liquid. This ensures both the fluxing effect and the stability of the zinc plating environment. The top of the fluxing tank 502 is connected to the first injection pipe 505, and the bottom of the fluxing tank 502 is connected to the first drain pipe 506. The first injection pipe 505 facilitates the replenishment of flux into the fluxing tank 502, and the first drain pipe 506 facilitates the replacement of waste flux, ensuring that the flux is always in good working condition, guaranteeing a stable fluxing effect, and improving the ease of operation of the device.

[0029] Reference Figure 3 , Figure 4 and Figure 5 The galvanizing mechanism 6 includes a galvanizing chamber 601 located inside the main processing box 1. A galvanizing tank 602 is installed on the inner bottom wall of the galvanizing chamber 601. A second guide wheel assembly 603 and a second electric heating tube 604 are installed inside the galvanizing tank 602. The second guide wheel assembly 603 is positioned above the second electric heating tube 604. In the galvanizing mechanism 6, the molten zinc in the galvanizing tank 602 is maintained at a suitable temperature under the action of the second electric heating tube 604. The second guide wheel assembly 603 guides the iron wire to form a reasonable temperature in the molten zinc. The motion trajectory ensures that the iron wire surface is evenly covered with a zinc layer, solving the problem of low coating quality in the background technology and enhancing the rust resistance of the iron wire. The top of the galvanizing tank 602 is connected to a second injection pipe 605, and the bottom of the galvanizing tank 602 is connected to a second drain pipe 606. The second injection pipe 605 facilitates the replenishment of zinc liquid to the galvanizing tank 602, and the second drain pipe 606 facilitates the discharge of impurities or waste zinc liquid in the tank, which helps to maintain the purity and performance stability of the zinc liquid and ensure the consistency of galvanizing quality in mass production.

[0030] The implementation principle of this application embodiment is as follows: the iron wire enters the device through the wire guide hole 7 at the inlet end of the main processing box 1. The high-temperature resistant silicone sealing ring 8 in the wire guide hole 7 can seal each cavity to prevent gas leakage or infiltration of outside air during subsequent processing. After entering the physical rust removal mechanism 2, the two brackets 201 respectively support the main steel wire brush roller 202 and the auxiliary steel wire brush roller 203. The servo motor 204 fixed on the outer surface of the lower bracket 201 drives the main steel wire brush roller 202 to rotate, and cooperates with the auxiliary steel wire brush roller 203 to perform friction cleaning on the surface of the iron wire, effectively removing rust, oxide scale and oil stains and other impurities, providing a clean surface for subsequent processing. After cleaning, the iron wire enters the heat treatment chamber 301 of the heat treatment mechanism 3. The first electric heating tube 302, which is evenly distributed on the inner wall, heats the chamber to a suitable temperature. The reducing gas delivery pipe 303 introduces reducing gas into the chamber to reduce the trace oxide layer remaining on the surface of the iron wire. The waste gas generated by the reaction is discharged through the exhaust pipe 304 installed on the outer surface of the main treatment box 1 to maintain a stable reducing atmosphere in the chamber. Subsequently, the iron wire enters the cooling chamber 401 of the oxygen-free cooling mechanism 4 through the corresponding wire guide hole 7 and the high-temperature resistant silicone sealing ring 8. Inert gas is introduced through the inert gas inlet pipe 406, while the oxygen exhaust pipe 407 discharges the initial air and any small amount of air that may have seeped into the chamber, thus creating an oxygen-free environment. Multiple rotatable hollow rollers 402 are interconnected through connecting pipes 403. Cooling water is introduced into the hollow rollers 402 through the water inlet pipe 404. The cooling water flows through all the hollow rollers 402 via the connecting pipe 403 and is discharged from the water outlet pipe 405. When the iron wire comes into contact with the hollow rollers 402, it achieves rapid cooling, avoiding secondary oxidation due to contact with air. After cooling, the iron wire enters the attachment chamber 501 of the flux attachment mechanism 5 through the corresponding wire guide hole 7 and the high-temperature resistant silicone sealing ring 8. The flux tank 502 stores flux, and new flux can be added through the first injection pipe 505 and waste flux can be discharged through the first drain pipe 506. The first guide wheel assembly 503 guides the iron wire to be completely immersed in the flux. The squeeze roller assembly 504 located above removes excess flux from the surface of the iron wire to prevent excessive flux from being carried into the subsequent zinc plating process and affecting the purity of the zinc liquid. Finally, the wire enters the galvanizing chamber 601 of the galvanizing mechanism 6 through the corresponding wire guide hole 7 and the high-temperature resistant silicone sealing ring 8. The zinc liquid in the galvanizing tank 602 is replenished through the second injection pipe 605 and the impurities in the tank are discharged through the second drain pipe 606. The second electric heating tube 604 heats the zinc liquid and maintains it at a suitable temperature. The second guide wheel assembly 603 guides the wire to form a reasonable movement trajectory in the zinc liquid, so that the surface of the wire is evenly covered with a zinc layer. After the galvanizing process is completed, the wire is sent out from the wire guide hole 7 at the outlet end of the main processing box 1.
