[0002] During the rolling process of the cold rolling production line, the strip steel needs to be sprayed with emulsion to cool it. After the strip steel is rolled, the emulsion will remain on the surface of the strip steel. If these emulsions are not cleaned up, the quality of the strip steel will be affected. In order to clean up the residual emulsion, equipment is needed to clean the surface of the strip steel.

[0003] Prior art CN216574887U discloses an emulsion cleaning device for use in a strip steel production workshop, which conveys the strip steel through a conveyor belt, and then cleans the emulsion on the surface of the strip steel through a cleaning component above the conveyor belt and a jet device. However, when the above cleaning device is working, since a lot of emulsion will remain on the surface of the strip steel, when the jet device sprays gas on the surface of the strip steel, it is easy to cause a large amount of emulsion to splash, polluting the working environment, and it can only clean the surface of one side of the strip steel, and the emulsion on the other side of the strip steel needs to be cleaned again, which reduces the efficiency of emulsion cleaning and brings great inconvenience to production work. Summary of the invention

[0004] The purpose of the embodiment of the present application is to provide an emulsion cleaning device for strip steel production, by setting a pretreatment mechanism, a first purge mechanism and a second purge mechanism. The pretreatment mechanism removes most of the emulsion on the surface of the strip steel, the first purge mechanism blows the emulsion away from the strip steel, reduces the emulsion residue on the surface of the strip steel, and improves the cleaning effect of the second purge mechanism. The second purge mechanism can synchronously purge the upper and lower ends of the strip steel, thereby improving the cleaning efficiency of the emulsion.

[0034] Example

[0035] like Figure 1-5As shown, the emulsion cleaning device for strip steel production described in the embodiment of the present application includes a base plate 1, a U-shaped cover 2, a pretreatment mechanism 3, a first purge mechanism 4 and a second purge mechanism 5. The U-shaped cover 2 is arranged on the base plate 1, the pretreatment mechanism 3 includes a first mounting seat 6 arranged at the upper and lower ends of the strip steel running direction and a scraper block 7 arranged on the first mounting seat 6, the first mounting seat 6 is located on the inner side of the U-shaped cover 2, the scraper block 7 abuts against the strip steel, the first purge mechanism 4 includes a mounting plate 8 and a high-pressure airflow pipe 9, the mounting plate 8 is arranged on the first mounting seat 6 at the upper end, the high-pressure airflow pipe 9 is arranged on the mounting plate 8, and the jet direction of the high-pressure airflow pipe 9 is perpendicular to the running direction of the strip steel, the second purge mechanism 5 includes a second mounting seat 10 arranged at the upper and lower ends of the strip steel running direction, a purge pipe 11 arranged on the second mounting seat 10 and a plurality of nozzles 12 arranged on the purge pipe 11, and the second mounting seat 10 is located on the inner side of the U-shaped cover 2.

[0036] During the conveying process of the strip, the scraper block 7 at the upper end of the strip scrapes off the emulsion on the upper surface of the strip, and the high-pressure airflow pipe 9 is used to spray high-pressure airflow to blow the emulsion away from the strip. Due to the provision of the U-shaped cover 2, part of the emulsion falls after contacting the U-shaped cover 2, thereby preventing the emulsion from splashing and polluting the external environment. The emulsion at the lower end of the strip falls under the action of gravity, and the residual amount of emulsion on the surface of the strip after pretreatment is greatly reduced. Subsequently, the nozzles 12 at the upper and lower ends of the strip simultaneously blow airflow to the surface of the strip to perform secondary cleaning of the emulsion on the surface of the strip, thereby improving the cleaning effect and cleaning efficiency of the emulsion on the surface of the strip.

[0037] In this embodiment, a collecting box 13 is provided on the bottom plate 1 , and the collecting box 13 is located at the inner lower end of the U-shaped cover 2 , so as to facilitate the collection of the emulsion.

[0038] In this embodiment, the scraper block 7 is wedge-shaped, and the emulsion scraped off the surface of the steel strip can flow downward along the scraper block 7 .

[0039] In this embodiment, there are two more nozzles 12 on the upper end purge tube 11 than on the lower end purge tube 11. The two more purge tubes 11 are used to purge the ends of the steel strip, ensuring that the surface of the steel strip is purged without dead angles.

[0040] In this embodiment, a first cylinder 14 is provided on the U-shaped cover 2. The first cylinder 14 drives the first mounting seat 6 at the upper end to rise and fall. The two ends of the first mounting seat 6 at the lower end are respectively fixedly connected to the U-shaped cover 2. When the first cylinder 14 drives the first mounting seat 6 at the upper end to rise, the distance between the first mounting seat 6 at the upper end and the first mounting seat 6 at the lower end becomes larger. When the first cylinder 14 drives the first mounting seat 6 at the upper end to move downward, the distance between the first mounting seat 6 at the upper end and the first mounting seat 6 at the lower end becomes smaller, thereby meeting the use requirements of strip steels of different thicknesses.

[0041] In this embodiment, a plurality of first telescopic rods 15 are disposed between the first upper mounting seat 6 and the U-shaped cover 2 to improve the stability of the first upper mounting seat 6 .

[0042] In this embodiment, a squeezing mechanism 16 is provided on the inner side of the U-shaped cover 2, and the squeezing mechanism 16 includes an upper squeezing roller 17 and a lower squeezing roller 18. The upper squeezing roller 17 and the lower squeezing roller 18 respectively abut against the upper and lower ends of the strip, and the upper squeezing roller 17 and the lower squeezing roller 18 respectively clean the upper and lower surfaces of the strip three times, thereby further improving the cleaning effect of the emulsion on the surface of the strip.

[0043] In this embodiment, the squeezing mechanism 16 also includes a second cylinder 19 and a mounting frame 20. The second cylinder 19 is arranged on the U-shaped cover 2. The second cylinder 19 drives the mounting frame 20 to rise and fall. The upper squeezing roller 17 is arranged on the mounting frame 20. The two ends of the lower squeezing roller 18 are respectively connected to the U-shaped cover 2. When the second cylinder 19 drives the mounting frame 20 to rise, the upper squeezing roller 17 moves up synchronously, and the distance between the upper squeezing roller 17 and the lower squeezing roller 18 increases. When the second cylinder 19 drives the mounting frame 20 to descend, the upper squeezing roller 17 moves down synchronously, and the distance between the upper squeezing roller 17 and the lower squeezing roller 18 decreases. This facilitates adjusting the distance between the upper squeezing roller 17 and the lower squeezing roller 18 according to usage requirements.

[0044] In this embodiment, a plurality of second telescopic rods 21 are provided between the installation frame 20 and the U-shaped cover 2 to improve the stability of the installation frame 20 and ensure the use effect of the upper squeeze roller 17 .

[0045] The working principle of an emulsion cleaning device for strip steel production in the embodiment of the present application is as follows:

[0046] During the conveying process of the strip, the scraper block 7 at the upper end of the strip scrapes off the emulsion on the upper surface of the strip, and the high-pressure airflow pipe 9 is used to spray high-pressure airflow to blow the emulsion away from the strip. Due to the provision of the U-shaped cover 2, part of the emulsion falls after contacting the U-shaped cover 2, thereby preventing the emulsion from splashing and polluting the external environment. The emulsion at the lower end of the strip falls under the action of gravity, and the residual amount of emulsion on the surface of the strip after pretreatment is greatly reduced. Subsequently, the nozzles 12 at the upper and lower ends of the strip simultaneously blow airflow to the surface of the strip to perform secondary cleaning of the emulsion on the surface of the strip, thereby improving the cleaning effect and cleaning efficiency of the emulsion on the surface of the strip.

[0047] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
