Description

Technical Field

[0001] This utility model relates to the field of pickling lines, and in particular to a surface cleaning device for pickling lines. Background Technology

[0002] Pickling is a process in the steel metallurgical industry used to remove iron oxide scale from the surface of steel strips. It removes scale and dirt from the surface of hot-rolled coils through mechanical and chemical action, providing clean strips for subsequent rolling. During the pickling process, the hot-rolled steel strip first enters a pickling tank to remove the scale, then enters a rinsing tank where it is cleaned with demineralized water to remove any remaining acid. Finally, a blowing device dries any remaining moisture on the surface of the steel strip to prevent yellowing and rusting.

[0003] The prior art can be referenced from Chinese authorized utility model patent with publication number CN220432992U, which specifically describes a compressed air dual-purging device for pickling steel strip production, comprising: a main air supply pipe, two branch air supply pipes, and a PLC control cabinet; characterized in that: a first purging device and a second purging device are provided on the pickling steel strip production line; the first or second purging device consists of an upper housing, an upper air blowing pipe, an upper nozzle, a lower housing, a lower air blowing pipe, and a lower nozzle; a photoelectric probe is provided at the front end of the first purging device; the two purging devices are respectively connected to the main air supply pipe through the branch air supply pipes; pneumatic butterfly valves are respectively provided on the two branch air supply pipes, and the two pneumatic butterfly valves are respectively controlled by their respective adapted electromagnetic reversing valves; the two electromagnetic reversing valves and the photoelectric probe are respectively connected to the PLC control cabinet through wires. This existing technology uses two sets of purging devices to simultaneously purge the upper and lower surfaces of the pickled steel strip, which allows the moisture on the steel strip surface to be dried quickly, improving the purging effect and avoiding yellowing and rust defects caused by water on the surface of the pickled steel strip. The surface of the pickled steel strip reaches a silvery white color. At the same time, it reduces the consumption of compressed air, saves time and labor, and improves production efficiency.

[0004] The aforementioned prior art has the following shortcomings in actual operation: Although the prior art can quickly dry the moisture on the surface of the steel strip, it leaves watermark outlines on the surface of the steel strip, affecting the aesthetics of the steel strip surface. Furthermore, dust in the air adheres to the surface of the steel strip during the drying process, resulting in some impurities remaining. Utility Model Content

[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of this utility model are now described with reference to the accompanying drawings. However, the scope of protection of this utility model is not limited to the following description.

[0029] Reference Figure 1-6 As shown, a surface purging device for an acid pickling line includes: an outer casing 1, with a fixing plate 16 connected to its right side;

[0030] The fixed plate 16 is rotatably connected to a bidirectional screw 17. The surface of the bidirectional screw 17 is threaded with an internal threaded ring 19. The rear side of the internal threaded ring 19 is connected to a fixed block 22. The rear side of the fixed block 22 is connected to an installation block 23. An installation groove 24 is opened on the rear side of the installation block 23. A sponge brush 25 is slidably connected to the inner wall of the installation groove 24.

[0031] The left side of the internal threaded ring 19 is connected to the slider 20; the front right side of the outer box 1 is provided with a sliding groove 21, and the inner wall of the sliding groove 21 is slidably connected to the surface of the slider 20.

[0032] A retaining groove 26 is provided on the rear side of the top of the mounting block 23. A retaining block 27 is slidably connected to the inner wall of the retaining groove 26. A control plate 28 is connected to the top of the retaining block 27.

[0033] A telescopic tube 29 is connected to the bottom front side of the control panel 28; a telescopic groove 30 is opened on the top front side of the mounting block 23, the bottom of the inner wall of the telescopic groove 30 is connected to the bottom of the telescopic tube 29, a spring 31 is connected to the bottom of the inner wall of the telescopic groove 30, the spring 31 is set on the outside of the telescopic tube 29, and the top of the spring 31 is connected to the bottom front side of the control panel 28.

[0034] A turntable 18 is connected to the center of the surface of the bidirectional screw 17; an outlet 15 is opened on the right side of the outer casing 1.

[0035] The present invention provides a technical solution in which, during use, one end of the sponge brush 25 is inserted into the mounting groove 24 until one side of the sponge brush 25 is in contact with the left side of the inner wall of the mounting groove 24. The control plate 28 is then released, and the telescopic tube 29 shortens under the elastic force of the spring 31 in the telescopic groove 30. This shortening of the telescopic tube 29 causes the control plate 28 to move downwards, which in turn causes the fixing block 27 to insert into the fixing groove 26, fixing the position of the sponge brush 25. This facilitates the replacement of the sponge brush 25 and reduces the later maintenance cost of the blowing device. After the surface moisture is dried, the steel strip opens from the right side of the outer casing 1. When the outlet 15 is removed, the rotating turntable 18 drives the bidirectional screw 17, which is rotatably connected to the fixed plate 16, to rotate. The rotation of the bidirectional screw 17 drives the internal threaded ring 19 to move towards each other. The movement of the internal threaded ring 19 drives the slider 20 to move towards each other along the inner wall of the slide groove 21. The movement of the internal threaded ring 19 drives the fixed block 22 to move towards each other. The movement of the fixed block 22 drives the mounting block 23 to move towards each other. The movement of the mounting block 23 drives the sponge brush 25 in the mounting groove 24 to move towards each other until its side is in contact with the upper and lower surfaces of the steel strip, respectively, cleaning the watermarks and attachments on the surface of the moving steel strip.

[0036] Preferably, the outer casing 1 has an inlet 2 on the left side, and the inner wall of the outer casing 1 is connected to the upper and lower parts of the partition 3, with an air outlet 4 at the bottom of the partition 3;

[0037] A main shaft 5 is connected to the front side of the inner wall of the air outlet 4. A guide plate 6 is installed inside the air outlet 4. A rotating hole 7 is opened on the upper front side of the guide plate 6. The inner wall of the rotating hole 7 is rotatably connected to the surface of the main shaft 5. A rotating rod 8 is slidably connected to the center of the front side of the guide plate 6. A drive plate 9 is connected to one end of the rotating rod 8. A connecting plate 10 is connected to the left side of the drive plate 9. An electric push rod 11 (model JIANGSU JIECANG-JC) is connected to the left side of the connecting plate 10. The electric push rod 11 and the air compressor 13 are both controlled by an external controller. One end of the electric push rod 11 is connected to the front left side of the inner wall of the outer casing 1.

[0038] A support plate 12 is connected to the front of the outer casing 1. An air compressor 13 is connected to the top of the support plate 12. A delivery pipe 14 is connected to the front of the air compressor 13. One end of the delivery pipe 14 is connected to the surface of the outer casing 1.

[0039] Specifically, when the steel belt enters the outer casing 1 through inlet 2, the air compressor 13 connected to the top of the support plate 12 starts. The air compressor 13 delivers the compressed air through the delivery pipe 14 to the space between the partition 3 and the outer casing 1. Then, the gas is blown towards the steel belt through the air outlet 4. By increasing the air flow rate, the purpose of accelerating the evaporation of moisture is achieved. The electric push rod 11 on the left side of the inner wall of the outer casing 1 starts the cabinet. The extension and retraction of the electric push rod 11 drives the connecting plate 10 to move. The movement of the connecting plate 10 drives the driving plate 9 to move. The movement of the driving plate 9 drives the rotating rod 8 to move. The movement of the rotating rod 8 drives the guide plate 6 with the rotating hole 7 to rotate around the main shaft 5. During the rotation of the guide plate 6, the gas blown towards the steel belt through the air outlet 4 changes the air outlet angle to blow away the moisture on the surface of the steel belt.

[0040] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
