[0035] The concept, specific structure and technical effects of the present application will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present application. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation.

[0036] As Figures 1 - 3 shown, a phosphating device for physical rust removal of wire rods includes:

[0037] A film-forming device 1, the film-forming device 1 includes a cleaning tank 11 for physically cleaning wire rods and a film-forming tank 12 for chemical film-forming. A cleaning mechanism 13 for removing the oxide layer on the surface of the wire rods is provided in the cleaning tank 11, and a circulation mechanism 14 for controlling the flow of the film-forming liquid is arranged in the film-forming tank 12;

[0038] A drying device 2, the drying device 2 is sequentially connected after the film-forming device 1, and the drying device 2 is provided with a heating mechanism 21 for uniformly drying the surface of the wire rods.

[0039] Specifically, first, the wire rods to be processed are physically cleaned through the cleaning tank. Using the built-in cleaning mechanism, the oxide layer on the surface is removed, and at the same time, roughness beneficial to subsequent chemical film-forming is formed on the surface of the wire rods. Then, the wire rods enter the film-forming tank. Under the control of the circulation mechanism, the film-forming liquid in the tank realizes uniform flow, ensuring that the surface of the wire rods is evenly covered with the film-forming liquid. Finally, after the film-forming is completed, the wire rods enter the drying device. This device uses the heating mechanism to heat, ensuring that the surface of the wire rods is evenly heated, realizing rapid and thorough drying, and avoiding quality problems caused by local overheating or uneven drying.

[0040] In one embodiment, the film-forming device 1 and the drying device 2 are connected through a transmission mechanism. Specifically, the transmission mechanism can be a conveyor belt.

[0041] The transmission mechanism, as the connection between the film-forming device 1 and the drying device 2, specifically adopts the form of a conveyor belt. The design of the conveyor belt takes into account the docking with the high-level tank 121 and the low-level tank 122 of the film-forming tank 12, ensuring that the wire rods can smoothly and continuously enter the drying device 2 after film-forming. At the same time, the speed of the conveyor belt is adjustable to meet the requirements of different production speeds.

[0042] In one embodiment, as Figure 2 、 3 shown, the film-forming device 1 and the drying device 2 are arranged in a "T" shape. Specifically, for the "T" shape structure, for the film-forming tank of the film-forming device, the tank body of the film-forming tank is arranged in a "T" shape, and the film-forming operation is carried out on the "one" part of the "T".

[0043] For a specific "T" - shaped structure, the heating position of the drying device for the wire is the "one" part of the "T". Therefore, in this application, the "T" - shaped structure design enables the film - forming device and the drying device to be compactly combined, reducing the floor area of the overall device, thus saving space and making the production layout more efficient. At the same time, through the "T" - shaped structure, the film - forming device and the drying device are sequentially connected, ensuring that the wire can seamlessly enter the drying stage after chemical film - forming, improving production efficiency and the continuity of the process.

[0044] In one embodiment, the heating mechanism 21 adopts a ring - shaped heating tube 211 to dry the wire 360°.

[0045] In the above - mentioned technical solution, the heating mechanism 21 adopts a ring - shaped heating tube 211, and the ring - shaped heating tube 211 can achieve 360° all - around heating of the wire. By precisely controlling the power and temperature of the ring - shaped heating tube, it is ensured that the wire is evenly heated during the drying process, avoiding local overheating or uneven drying, and improving the drying efficiency and the quality of the wire after drying.

[0046] In one embodiment, the drying device 2 has an inlet 15 and an outlet 16. The inlet 15 and the outlet 16 of the drying device 2 are the key channels for the wire to enter and leave the drying device 2.

[0047] In one embodiment, as Figure 4 shown, the cleaning mechanism 13 includes a steel brush 131 and a high - pressure spray head 134; a steel brush 131 is provided on the cleaning tank 11, and a high - pressure water pump 132 is provided at the bottom of the cleaning tank 11; the high - pressure water pump 132 is provided with a water pump inlet 133 and a high - pressure spray head 134.

[0048] In the above - mentioned technical solution, the steel brush 131 in the cleaning mechanism 13 is made of wear - resistant material and is fixed on the inner wall of the cleaning tank (11), effectively removing the oxide layer on the surface of the wire through physical friction. The high - pressure water pump 132 introduces water through the water pump inlet 133, and the water flow generated by the high pressure is sprayed on the wire from multiple directions through the high - pressure spray head 134. Not only is the cleaning effect remarkable, but it can also form a certain roughness on the surface of the wire, providing good surface conditions for the subsequent film - forming process.

[0049] In one embodiment, as Figure 5 、 6 shown, the main body of the film - forming tank 12 is in a T - shape, a high - level tank 121 is provided on the upper part of the main body of the tank, and a low - level tank 122 is provided in the high - level tank 121;

[0050] The high - level tank 121 is provided with an inlet 15 and an outlet 16;

[0051] The low-level tank 122 is provided with an overflow port 1221 and a number of limiting holes 1222; the limiting holes 1222 are located above the overflow port 1221.

[0052] The setting of the high-level tank 121 and the low-level tank 122 enables the wire to be fully immersed in the low-level tank 122 during the film-forming process, then overflow through the limiting holes 1222 to the high-level tank 121, and then return to the low-level tank 122 through the overflow port 1221, forming a cycle, ensuring the uniformity of the bath liquid and the full film-forming of the wire.

[0053] The inlet port 15, the outlet port 16, and the limiting holes 1222 are on a straight line. This design enables the wire to directly align with the limiting holes 1222 when entering the film-forming tank, maintaining a stable position during the film-forming process, avoiding the problems of wire deviation and uneven film-forming. At the same time, this layout also simplifies the structure of the film-forming tank, reducing the complexity of manufacturing and maintenance.

[0054] Specifically, the high-level tank and the low-level tank are used to store the bath liquid; heating pipes are provided on both sides inside the film-forming device to heat the bath liquid and ensure uniform bath liquid temperature.

[0055] The "T" - shaped design of the film-forming tank, especially the setting of the high-level tank and the low-level tank, helps the bath liquid to circulate during the film-forming process, ensuring that the wire is fully immersed in the low-level tank, uniformly covered with the film-forming liquid, overflowing through the limiting holes to the high-level tank, and then flowing back to the low-level tank, forming an effective cycle to ensure the uniformity of film-forming.

[0056] In one embodiment, a stirring paddle 17 is provided inside the tank body. A motor is provided at the top of the tank body, and the lower end of the motor is connected to the stirring paddle for stirring the bath liquid to ensure the uniformity of the bath liquid. In this application, the stirring paddle 17 is installed inside the tank body of the film-forming tank 12, driven by the motor, and the bath liquid is stirred through the stirring paddle connected to the lower end of the motor. The design of the stirring paddle takes into account the characteristics of the bath liquid and the requirements of the film-forming process, adopting a suitable shape and size to achieve an efficient stirring effect. The setting of the stirring paddle not only ensures the uniformity of the bath liquid but also helps to improve the rate and quality of the film-forming reaction.

[0057] At the same time, temperature control probes are respectively provided on both sides of the tank body to monitor the temperatures at both ends of the bath liquid; through the heating pipes on both sides and the stirring device, the bath liquid is heated evenly and the temperature is kept consistent. Therefore, by installing the temperature control probes on both sides of the film-forming tank, the temperatures at both ends of the bath liquid can be detected respectively. Through real-time monitoring by the temperature control probes and adjusting the heating temperature in combination with the heating pipes, it can ensure uniform temperature distribution of the bath liquid and avoid differences in film-forming quality caused by uneven temperature.

[0058] In one embodiment, a circulation mechanism 14 is provided inside the tank body, and the circulation mechanism 14 includes a submersible pump 141;

[0059] The submersible pump 141 is arranged at the bottom of the tank body. The submersible pump 141 is provided with a tank liquid inlet 142 and a tank liquid outlet 143. The tank liquid inlet 142 is arranged at the bottom of the tank body, and the tank liquid outlet 143 is arranged at the bottom of the low-level tank 122.

[0060] In this application, the submersible pump 141 in the circulation mechanism 14 is installed at the bottom of the tank body of the film-forming tank 12. The tank liquid is sucked from the bottom of the tank body through the tank liquid inlet 142, and then the tank liquid is transported to the high-level tank 121 through the tank liquid outlet 143 to realize the circulating flow of the tank liquid. This design not only improves the circulation efficiency of the tank liquid, but also helps to keep the temperature and concentration of the tank liquid uniform, providing a uniform film-forming environment for the wire. The installation position and working mode of the submersible pump 141 ensure the continuity and stability of the tank liquid circulation.

[0061] The phosphating device described in this application operates as follows:

[0062] Before film formation, start the heating tube of the film-forming tank to heat the tank liquid, and use the stirring paddle to stir evenly; at the same time, turn on the submersible pump. The tank liquid is pumped from the bottom of the tank body of the film-forming tank to the upper end of the tank through the tank liquid inlet of the submersible pump, and flows out from the tank liquid outlet of the submersible pump, and the tank liquid circulates inside the tank body.

[0063] At the same time, turn on the drying equipment and use the annular heating tube for heating until the tank liquid and the drying equipment are heated to the required temperature; put the wire to be film-formed that has been peeled or shot-peened into the cleaning tank. After the wire to be film-formed removes the remaining scale by the steel brush, the high-pressure water pump pumps the water in the cleaning tank through the high-pressure pump inlet, and the high-pressure nozzle sprays water from multiple directions to wash the wire to be film-formed clean, and forms a certain roughness on the surface of the wire to be film-formed to facilitate film formation. After washing clean, the washed wire is obtained; the washed wire enters from the high-level tank inlet, and then enters the low-level tank through the low-level tank limiting hole, and the film-forming reaction is completed in the low-level tank. At this time, the tank liquid will overflow from the low-level tank limiting hole to the high-level tank, and the overflowed tank liquid will flow back into the low-level tank through the low overflow port to prevent the liquid in the tank from flowing out of the tank body.

[0064] The wire after film formation exits through the high-level tank outlet, can pass through the conveying mechanism, enter the conveyor belt, etc., enter the drying equipment from the drying equipment inlet, and after the wire is dried in all directions by the annular heating tube in the drying equipment, it exits from the drying equipment outlet, and then the film-forming and drying process is completed after winding.

[0065] The above is a specific description of the preferred embodiment of the present application. However, the present invention is not limited to the described embodiment. Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present application. These equivalent deformations or substitutions are all included within the scope defined by the claims of the present application.
