Description

Technical Field

[0001] This utility model relates to the field of degreasing technology for hot-dip galvanized steel strips, specifically to a high-efficiency degreasing device for hot-dip galvanized steel strips. Background Technology

[0002] Degreasing of hot-dip galvanized steel strip refers to the process of removing various oil stains and impurities adhering to the surface of hot-dip galvanized steel strip through physical, chemical, or combined physical and chemical methods before production, processing, or subsequent applications (such as stamping and coating).

[0003] Currently, in the degreasing of hot-dip galvanized steel strip using sodium hydroxide via saponification, the oil produced during degreasing floats on the surface of the solution. If this floating oil is not promptly removed during subsequent unloading of the degreased steel strip, it easily re-adheres to the strip surface, affecting the actual degreasing effect. Furthermore, a secondary degreasing process is required, which is time-consuming and labor-intensive, further reducing efficiency. Therefore, a high-efficiency degreasing device for hot-dip galvanized steel strip is needed to address these drawbacks and improve the overall performance. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To make the objectives, technical solutions and advantages of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 As shown, this utility model is a high-efficiency degreasing device for hot-dip galvanized sheet and strip, comprising: The degreasing soaking tank 11 has a first support rod 12 on one side, and a first connecting pipe 14 is connected through the upper end of the first support rod 12. A blower pipe 15 is fixed to the top of the inner side of the first support rod 12, and the top of the blower pipe is connected to one end of the first connecting pipe 14. The other end of the first connecting pipe 14 is connected to an external blower. A guide plate 16 is threaded to one end inside the degreasing soaking tank 11. A plurality of rolling grooves 17 are equidistantly arranged on one side of the guide plate 16, and guide balls 18 are arranged in the plurality of rolling grooves 17. The degreasing soaking tank 11 stores sodium hydroxide solution, and degreasing is achieved by soaking the hot-dip galvanized sheet and strip and generating a saponification reaction. The first support rod 12 provides the structural foundation installation environment. The first connecting pipe 14 is connected to the external blower. The blower pipe 15 acts on the upper surface of the solution to concentrate the floating oil to one side. The rolling groove 17 accommodates the installation of multiple guide balls 18. The guide plate 16, together with the multiple guide balls 18, can conveniently pick up the degreased hot-dip galvanized sheet and strip.

[0018] The lower part of the first support rod 12 has a first opening extending to the lower part of one side of the degreasing soaking tank 11, and a first positioning post 13 is sleeved in the first opening; The first positioning pin 13 fits into the first positioning hole to install and fix the first support rod 12.

[0019] The guide plate 16 is trapezoidal and forms a 60° angle with the horizontal plane, and the upper part of the guide plate 16 extends into the degreasing soaking tank 11.

[0020] Working principle: In the degreasing process, the hot-dip galvanized steel strip is placed in a degreasing soaking tank 11 containing sodium hydroxide solution. The two react through a saponification reaction to remove the oil. The oil residue formed by the degreasing process floats on the surface of the solution. At this time, the first connecting pipe 14 is connected to an external blower, and the floating oil residue is concentrated and blown to one side through the blower pipe 15. When the degreased hot-dip galvanized steel strip is subsequently removed, the hot-dip galvanized steel strip is brought into contact with multiple guide balls 18 on the guide plate 16, and under the application of drag force, the degreased hot-dip galvanized steel strip is conveniently and quickly removed from the degreasing soaking tank 11, completing the removal process.

[0021] This solution avoids contact between the degreased hot-dip galvanized sheet and the floating oil during material handling, reducing the probability of subsequent secondary degreasing, saving time and effort, and significantly improving degreasing efficiency.

[0022] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment: It also includes an auxiliary oil removal component, which includes a perforated block 25 and an oil-absorbing cotton 28. Two perforated blocks 25 are arranged symmetrically. A rotating motor 26 is connected through the upper part of one perforated block 25, and a shaft 27 is fixed to the output end of the rotating motor 26. The middle part of one side of the outer surface of the shaft 27 is fixed to the top of the oil-absorbing cotton 28. The hole block 25 provides the structural installation base, the rotating motor 26 provides the power required for the rotation of the oil-absorbing cotton 28, and the shaft 27 supports the oil-absorbing cotton 28 and realizes the transmission of force, so that the oil-absorbing cotton 28 can concentrate and absorb and clean the floating oil blown in.

[0023] The bottom ends of the two holes 25 are fixed with positioning blocks, and the positioning blocks are connected to the degreasing soaking tank 11 by positioning bolts that pass through the middle. The positioning bolts fix the positioning block, and then the structural installation of the hole block 25 is completed by the fixed positioning block.

[0024] The auxiliary oil removal assembly also includes a second support rod 21. A second connecting pipe 23 is connected through one side of the upper end of the second support rod 21. An adsorption pipe 24 is fixed to the top of the inner side of the second support rod 21. The top of the adsorption pipe 24 is connected to one end of the second connecting pipe 23. The other end of the second connecting pipe 23 is connected to an external vacuum adsorption machine. The adsorption pipe 24 is in contact with the 90° angle flipped oil-absorbing cotton 28. The second support rod 21 provides the structural installation base. By connecting the second connecting pipe 23 to the external vacuum adsorption machine, and using the adsorption pipe 24, the oil-absorbing cotton 28 after being turned over can be cleaned and degreased, ensuring the reuse of the oil-absorbing cotton 28.

[0025] The lower part of the second support rod 21 has a second positioning hole extending to the lower part of the other side of the degreasing soaking tank 11, and a second positioning post 22 is fitted in the second positioning hole. The fitting of the second positioning pin 22 and the second positioning hole secures the second support rod 21.

[0026] Working principle: After blowing the floating oil to one side, the rotating motor 26 and the shaft 27 adjust the angle of the oil-absorbing cotton 28, that is, adjust the oil-absorbing cotton 28 to an angle where its lower end is perpendicular to the horizontal plane, and make it in contact with the floating oil to achieve adsorption. After the floating oil is adsorbed, the rotating motor 26 adjusts the angle of the oil-absorbing cotton 28 again, that is, rotates it to a 90° angle, so that the oil-absorbing cotton 28 and the adsorption tube 24 are in contact with each other. At this time, the vacuum negative pressure generated by the external vacuum adsorption machine can remove oil from the oil-absorbing cotton 28. After the oil is removed, the above steps are repeated to adsorb the oil.

[0027] This solution eliminates the need to replace the oil-absorbing cotton 28 repeatedly to absorb and clean oil stains, further reducing the probability of oil stains re-adheding to the hot-dip galvanized steel strip during material handling and further improving the performance.

[0028] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
