[0002] Hot-dip galvanization is an important surface treatment method widely used in the protection of steel. By immersing steel in molten zinc, a zinc coating with good corrosion resistance is formed on its surface, thereby effectively extending the service life of the steel and improving its adaptability and reliability in different environments. In many industrial fields, such as construction, bridges, automobile manufacturing, power transmission, etc., hot-dip galvanized steel plays an indispensable role.

[0003] The thickness of the galvanized layer on the surface of hot-dip galvanized steel needs to be controlled and adjusted by using the prior art such as the one with the publication number CN221275855U. Although this prior art can drive the lifting plate to move up and down by retracting and releasing the fixing rope, it can avoid device failures and waste of zinc liquid, thereby improving the practicability of the device. And by starting the first motor to drive the rotating plate to rotate, it can fix materials of different specifications and improve the galvanizing effect, thereby improving the working efficiency of the device. However, the steel in this prior art is galvanized at normal temperature, and the time for the steel to reach the temperature required for the galvanizing process is relatively long, which will affect the galvanizing efficiency.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Referring to the attached Figure 1 - attached Figure 5 , the present utility model provides a device for adjusting the thickness of the galvanized layer of hot-dip galvanized steel, including a zinc pot 2 installed on the top of the base 1 for storing galvanized liquid, and a functional component for recovering the waste heat of the galvanized liquid is provided outside the base 1;

[0028] The functional component includes a box body 3 arranged on one side of the zinc pot 2. Inside the box body 3, a wavy absorption tube 4 is installed. The top of the absorption tube 4 is fixedly communicated with a plurality of air pipes 5 distributed at intervals. The top ends of the air pipes 5 penetrate through the box body 3 and extend to the top of the box body 3. One end of the absorption tube 4 close to the zinc pot 2 penetrates through the box body 3 and extends to one side of the zinc pot 2, and an air pump 6 is installed outside the absorption tube 4 at the end close to the zinc pot 2. A connecting pipe 7 is fixedly communicated with the outside of the zinc pot 2 corresponding to one side of the absorption tube 4. A filtering component for filtering impurities is arranged between the absorption tube 4 and the connecting pipe 7.

[0029] The worker starts the air pump 6 to convey the high-temperature steam in the zinc pot 2 to the inside of the absorption tube 4 through the connecting pipe 7, and then the absorption tube 4 conveys the high-temperature steam to the top of the box body 3 through the air pipes 5. Among them, since a support frame 23 is installed on the top of the box body 3 and a filter plate 24 is installed inside the support frame 23, the steel to be processed placed on the top of the filter plate 24 can be in contact with the high-temperature steam. Thus, the steel can be preheated by using the high-temperature steam, and the preheated steel can shorten the time required to reach the temperature required for the galvanizing process, so as to complete the galvanizing process faster and improve the production efficiency.

[0030] Also, since the filtering component includes a transfer cylinder 8 arranged between the absorption tube 4 and the connecting pipe 7, one ends of the connecting pipe 7 and the absorption tube 4 close to each other are fixedly communicated with the transfer cylinder 8. A fitting plate 9 is screwed inside the bottom end of the transfer cylinder 8, and a filter ring 10 extending into the transfer cylinder 8 is installed on the top of the fitting plate 9. Thus, the filter ring 10 in the transfer cylinder 8 can filter impurities in the high-temperature steam, avoiding the impurities from adhering to the outside of the steel and affecting the galvanizing effect. At the same time, the fitting plate 9 is screwed to the transfer cylinder 8. Thus, when the worker rotates the fitting plate 9, the filter ring 10 not restricted by a limit can be conveniently removed, thereby improving the convenience of overhauling and maintaining the filter ring 10.

[0031] When processing galvanized steel, it is necessary to facilitate the taking of the heated steel. As Figures 1-3 shown, a top plate 11 is arranged on the top of the base 1, and a plurality of support columns 12 for connecting the base 1 are installed at the bottom of the top plate 11. An installation plate 13 is arranged at the bottom of the top plate 11, and an electric slide rail 14 is installed at the bottom of the installation plate 13. A moving plate 15 is arranged at the bottom end of the electric slide rail 14, and the top of the moving plate 15 is fixedly connected with the bottom of the sliding seat 16 on the electric slide rail 14. The sliding seat 16 on the electric slide rail 14 drives the moving plate 15 to move to the top of the box body 3. Then, since two electric push rods 17 distributed at intervals are installed on the top of the top plate 11, and two positioning columns 18 distributed at intervals are arranged between the two electric push rods 17. The bottom ends of the electric push rods 17 and the bottom ends of the positioning columns 18 penetrate through the top plate 11 and are fixedly connected with the top of the installation plate 13. Thus, the electric push rods 17 can drive the installation plate 13 to move downwards, and the moving plate 15 on the installation plate 13 can be displaced to a proper height.

[0032] Among them, to improve the practicability of the present utility model, it is necessary to adapt to steel materials of different specifications, such as Figure 2 and Figure 3 As shown, a groove 19 is formed at the bottom of the moving plate 15. A threaded rod 20 movably connected through a bearing is installed inside the groove 19, and the thread directions of the two ends of the threaded rod 20 are opposite. Clamping plates 21 extending to the bottom of the moving plate 15 are threadedly connected to the outer parts of the two ends of the threaded rod 20; a servo motor 22 is installed at one end of the moving plate 15. The output shaft of the servo motor 22 penetrates the moving plate 15 and is fixed to one end of the threaded rod 20. By driving the threaded rod 20 to rotate through the servo motor 22, since the cross-sections of the clamping plates 21 and the groove 19 are both rectangular, and the outer parts of the clamping plates 21 are in contact with the inner wall of the groove 19, the threaded rod 20 can drive the two clamping plates 21 limited by the groove 19 to displace synchronously inward, so that the two clamping plates 21 can fix steel materials of different specifications. Then, it is shifted to the galvanizing pot 2 by means of the sliding seat 16 and the electric push rod 17 on the above-mentioned electric slide rail 14, and the steel material on the clamping plate 21 is brought into contact with the galvanizing solution in the galvanizing pot 2 to achieve the effect of galvanizing the steel material. Moreover, by the telescoping of the electric push rod 17, the contact amount between the steel material and the galvanizing solution can be adjusted, thereby achieving the effect of adjusting the galvanizing thickness.

[0033] Finally: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
