Description

Technical Field

[0001] This utility model provides an integrated device for rust removal and corrosion prevention on steel surfaces, belonging to the technical field of steel rust removal and corrosion prevention equipment. Background Technology

[0002] Steel, as the skeletal material of modern industrial society, is widely used in various fields such as construction, bridges, ships, and machinery. However, steel is highly susceptible to electrochemical reactions with moisture and oxygen in the air under natural environments or specific working conditions, leading to surface corrosion. Corrosion not only weakens the load-bearing cross-section of steel, reducing its mechanical properties and durability, but may also cause structural safety hazards. Therefore, thoroughly removing rust and applying an effective anti-corrosion coating before putting steel into use or during its maintenance is a crucial step in preventing contact with corrosive media and extending its service life; the necessity of this process is beyond question.

[0003] Currently, the surface treatment of steel often employs a step-by-step approach. This involves first removing rust through acid immersion; then, the steel is removed from the rust-removal equipment and transferred to a separate spraying area or equipment for anti-corrosion coating application. However, this traditional step-by-step approach has significant drawbacks. Especially after acid pickling, acidic working fluid remains on the steel surface. Direct spraying with this residual acid severely damages the coating's adhesion and curing effect, leading to anti-corrosion failure. Therefore, an additional drying process must be added after rust removal and before spraying to thoroughly remove residues. This not only increases equipment and space investment but also makes the entire process lengthy and cumbersome, requiring multiple transfers and clamping of workpieces, resulting in low operational efficiency and increased production costs. Utility Model Content

[0004] The technical problem this utility model aims to solve is that rust removal, drying, and anti-corrosion spraying of steel often require different equipment, which increases the investment in equipment and space, and the process is lengthy and cumbersome.

[0005] To solve the above problems, the proposed technical solution is as follows: an integrated device for rust removal and corrosion prevention of steel surface, including a rust removal cylinder containing acid solution; a steel plate is suspended above the rust removal cylinder by a lifting frame; The rust-removing cylinder is equipped with an end cap that covers the upper opening of the cylinder. A rotating mechanism is located beside the rust-removing cylinder, capable of rotating the end cap to open the upper opening. A column is located beside the rust-removing cylinder, and a support plate is rotatably connected to the column. A drying tube is located on one side of the support plate for drying the rust-removed steel plate, and an anti-corrosion spray nozzle is located on the other side of the support plate for spraying an anti-corrosion coating onto the dried steel plate. A receiving cylinder for collecting acid, wastewater, and anti-corrosion liquid is fixedly connected to the end cap.

[0006] Preferably, the rotating mechanism includes a rotating motor and a rotating shaft; the rotating motor is mounted on the ground, and the rotating shaft, which is fixedly connected to the output shaft of the rotating motor, is fixedly connected to the end cover.

[0007] Preferably, the receiving cylinder is located directly below the steel plate, and a drain pipe is connected to the bottom of the receiving cylinder.

[0008] Preferably, the support plate is connected to a drying connecting pipe, and the drying connecting pipe is connected to a plurality of drying pipes; the support plate is connected to an anti-corrosion connecting pipe, and the anti-corrosion connecting pipe is connected to a plurality of anti-corrosion nozzles.

[0009] Preferably, a motor slot is provided inside the column, and a tilting motor is installed inside the motor slot; the working end of the tilting motor is fixedly connected to a tilting shaft, and the tilting shaft passes through the column and is fixedly connected to the support plate.

[0010] Preferably, an adjusting motor is installed inside the lifting frame, and an adjusting shaft is fixedly connected to the working end of the adjusting motor; a rotating plate is fixedly connected below the adjusting shaft, and a steel plate is suspended and fixed below the rotating plate.

[0011] The beneficial effects of this utility model are: 1. This device, through its integrated structural design, effectively solves the problems of scattered equipment and poor process coordination in existing technologies. By incorporating openable end caps and rotatable support plates, it enables rapid and seamless switching between workstations for pickling, rust removal, drying, and anti-corrosion spraying. Once the steel plate is clamped, all processing can be completed sequentially, eliminating the need for frequent workpiece transfers between independent units, significantly improving operational efficiency, and reducing the required space.

[0012] 2. The receiving cylinder can collect dripping residual acid and anti-corrosion spray, preventing corrosive liquids from contaminating the working environment and the anti-corrosion spray from causing pollution. The end cap, fixedly connected to the receiving cylinder, seals the upper part of the rust removal cylinder, preventing residual acid, cleaning water, and anti-corrosion spray from the steel plate from entering the cylinder, offering significant advantages in ease of operation.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Reference Appendix Figure 1 , 2 An integrated device for rust removal and corrosion prevention of steel surfaces includes a rust removal cylinder 1 containing acid; a steel plate 4 is suspended above the rust removal cylinder 1 via a lifting frame 5; the lifting frame 5 is connected to an external lifting device, which allows the steel plate 4 to be lifted and raised by operating the external lifting device; the lifting device is a commonly used existing device, and this application directly connects the external lifting device to the lifting frame 5 without modifying the lifting device itself, therefore, the lifting device will not be described in detail here.

[0020] Reference Appendix Figure 2 The rust removal cylinder 1 is equipped with an end cap 2, which covers the upper opening of the rust removal cylinder 1. A rotating mechanism is located beside the rust removal cylinder 1, capable of rotating the end cap 2 to open the upper opening of the rust removal cylinder 1. The rotating mechanism includes a rotating motor 8 and a rotating shaft 9. The rotating motor 8 is located on the ground, and the rotating shaft 9, which is fixedly connected to the output shaft of the rotating motor 8, is fixedly connected to the end cap 2. By starting the rotating motor 8, the end cap 2 can be moved away from the rust removal cylinder 1, opening the upper opening of the rust removal cylinder 1 (during rust removal), or the end cap 2 can be moved to cover the opening of the rust removal cylinder 1 (during cleaning and anti-corrosion spraying of the steel plate 4). A receiving cylinder 3 is fixedly connected to the end cap 2, capable of collecting acid, wastewater, and anti-corrosion liquid, preventing waste liquid from entering the rust removal cylinder 1 while also collecting the waste liquid. The receiving cylinder 3 is located directly below the steel plate 4, and a drain pipe 16 is connected to the bottom of the receiving cylinder 3 for easy discharge of waste liquid.

[0021] Reference Appendix Figure 4A column 7 is set next to the rust removal cylinder 1, and a support plate 6 is rotatably connected to the column 7; a motor slot is opened in the column 7, and a flip motor 17 is set in the motor slot; a flip shaft 189 is fixedly connected to the working end of the flip motor 17, and the flip shaft 189 passes through the column 7 and is fixedly connected to the support plate 6. Reference Appendix Figure 3 The support plate 6 has a drying pipe 13 on one side for drying the rust-removed steel plate 4, and an anti-corrosion spray nozzle 12 on the other side for spraying an anti-corrosion coating onto the dried steel plate 4. A drying connecting pipe 14 is connected to the support plate 6 and is connected to several drying pipes 13. An anti-corrosion connecting pipe 15 is connected to the support plate 6 and is connected to several anti-corrosion spray nozzles 12. An external air source or hot air equipment supplies air to the drying pipe 13 through the drying connection pipe 14, while an external anti-corrosion spraying equipment supplies coating to the anti-corrosion spray nozzle 12 through the anti-corrosion connection pipe 15. The external air source, hot air equipment, and anti-corrosion spraying equipment are all direct applications of existing technology, and their specific structures and principles will not be elaborated upon here. Reference Appendix Figure 2 An adjusting motor 11 is installed inside the hanging frame 5, and an adjusting shaft is fixedly connected to the working end of the adjusting motor 11. A rotating plate 10 is fixedly connected below the adjusting shaft, and the steel plate 4 is suspended and fixed below the rotating plate 10. By installing the adjusting motor 11 inside the hanging frame 5, the steel plate 4 can be rotated through the rotating plate 10, thereby increasing the completeness of the correspondence between the drying tube 13, the anti-corrosion nozzle 12 and the steel plate 4.

[0022] When using the device described in this application, please refer to the attached document. Figure 1 , 2 First, the rotating mechanism motor 8 is started, driving the rotating shaft 9 to rotate the end cover 2, opening the upper opening of the rust removal cylinder 1 (the receiving cylinder 3 simultaneously moves away from the steel plate 4). The lifting frame 5 is connected to external lifting equipment. Through the lifting equipment and the lifting frame 5, the steel plate 4 to be treated is lowered and immersed in the acid solution of the rust removal cylinder 1 for chemical rust removal. After rust removal, the lifting frame 5 lifts the steel plate 4 above the rust removal cylinder 1 and places it stationary. At this time, the rotating motor 8 can be controlled again to rotate the end cover 2 back to the closed position, covering the upper opening of the rust removal cylinder 1. At the same time, the receiving cylinder 3 on the end cover 2 moves exactly below the steel plate 4, ready to catch the residual acid solution dripping from the steel plate 4. Next, the workers can use an external water pipe to rinse the steel plate 4. The rinsed wastewater falls directly into the receiving cylinder 3 without turbulence.

[0023] After cleaning, refer to the attached document. Figure 3 , 4The tilting motor 17 inside the column 7 is activated, driving the support plate 6 to rotate so that the side with the drying pipe 13 faces the steel plate 4. An external air source or hot air equipment supplies air to the drying pipe 13 through the drying connection pipe 14 to blow and dry the surface of the steel plate 4, removing moisture. (Simultaneously, the adjusting motor 11 inside the hanger 5 can be activated, rotating the steel plate 4 via the rotating plate 10, thus drying the steel plate 4 thoroughly.) After drying, the tilting motor 17 is controlled to rotate the support plate 6 180 degrees, turning the side with the anti-corrosion spray nozzle 12 towards the steel plate 4. External anti-corrosion spraying equipment supplies paint to the anti-corrosion spray nozzle 12 through the anti-corrosion connection pipe 15, spraying the dried steel plate 4. (During this process, the adjusting motor 11 inside the hanger 5 can slowly rotate the rotating plate 10 and the steel plate 4 via the adjusting shaft to ensure uniform drying and spraying.) Dripping paint and any remaining liquid are collected by the receiving cylinder 3 below and centrally treated through the drain pipe 16 at its bottom. Once all the procedures are completed, the treated steel plate 4 can be lifted away.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
