Description

Technical Field

[0001] This invention relates to the field of spray coating application on the inner surface of oil storage tanks, and in particular to a method, system and equipment for controlling the spray coating on the inner surface of oil storage warehouses. Background Technology

[0002] Oil storage tanks are large, regularly shaped containers used for storing petroleum products. They are widely used in refineries, oil fields, oil depots, and other industrial sectors. Oil storage tanks consist of a domed top and vertical cylindrical walls, primarily used for storing non-volatile oils such as diesel and similar products. The inner walls of oil storage tanks are in constant contact with the oil. Moisture, impurities in the oil, and oxygen in the air cause the tank walls to rust. The rust layer continuously flakes off, not only contaminating the oil but also accelerating the corrosion of the tank walls, shortening the tank's lifespan. Rust particles in the rust layer may mix into the oil, affecting its purity and quality. Simultaneously, the rust layer thins the tank walls, reducing the tank's pressure-bearing capacity and increasing the risk of explosion or leakage. The rust layer can also become a breeding ground for microorganisms, further exacerbating corrosion and safety hazards. Therefore, it is necessary to use spraying equipment to remove rust from the inner surface of oil storage tanks.

[0003] Common methods for spraying the inner surface of oil storage tanks: Rust removal and spraying on the inner surface of oil storage tanks mostly rely on manual operation. Advantages: Manual operation allows for flexible adjustment of rust removal and spraying methods and intensity based on the actual conditions of the tank's inner surface, such as the distribution and thickness of the rust layer and the shape of special areas. For example, manual processing can be more precise for irregular or narrow areas. Disadvantages: Low efficiency, incomplete rust removal, uneven spraying, and a harsh working environment pose certain health risks to operators. Furthermore, traditional methods make it difficult to monitor the rust removal and spraying effects in real time and adjust operating parameters promptly, leading to inconsistent work quality. Therefore, this paper proposes a method, system, and equipment for controlling the spraying of the inner surface of oil storage tanks. Summary of the Invention

[0004] This invention provides the following technical solution: a method for controlling the spraying of coatings on the inner surface of an oil storage warehouse, comprising the following steps: S1 device initialization: Start the equipment and perform self-tests and initialization settings for the control terminal, sandblasting system, oil spraying system, camera detection system, dust collection mechanism, rotating structure, and spraying system; S2 parameter settings: Based on the specifications, material, and rust condition of the inner surface of the oil storage tank, the operating parameters such as sandblasting pressure, sandblasting angle, spraying flow rate, and spraying speed are set through the control terminal. S3 sandblasting rust removal operation: According to the preset sandblasting parameters, the rotating structure is controlled to make the sandblasting system perform sandblasting and rust removal on the inner surface of the oil storage tank according to the preset trajectory and angle. At the same time, the camera detection system monitors the rust removal in real time and transmits the image data to the control terminal. S4 Performance Evaluation and Adjustment: The control terminal analyzes the image data transmitted by the camera detection system to evaluate the rust removal effect. If the rust removal is not thorough, the parameters of sandblasting pressure and angle are adjusted, and the sandblasting operation continues until the preset rust removal standard is achieved. S5 Vacuuming and Cleaning: During the sandblasting and rust removal process, the dust collection mechanism continuously absorbs the generated dust; S6 spraying operation: According to the preset spraying parameters, the spraying system is controlled to spray the inner surface of the rust-removed oil tank, while the camera detection system monitors the spraying situation in real time. S7 coating quality inspection: The spraying quality is inspected using a camera detection system. If the quality fails the inspection, the spraying parameters are adjusted and a local touch-up spraying operation is performed. S8 device reset and shutdown: After the operation is completed, control the rotating structure to reset the sandblasting system, and shut down the sandblasting system, the spraying system, and the dust collection mechanism; S9 Data Recording and Analysis: Record and analyze the various parameters, rust removal effect, and spraying quality data of this operation to provide a reference for subsequent operations; S10 Remote Monitoring and Early Warning: Establish a remote monitoring platform to receive equipment operating status and work data in real time, and send early warning information in a timely manner.

[0005] This control method automates the spraying operation on the inner surface of the oil storage tank through an automated control process, reducing manual intervention and improving work efficiency. By monitoring and adjusting operating parameters in real time, such as sandblasting pressure, spraying flow rate, and spraying speed, it ensures thorough rust removal and uniform spraying, improving work quality. Furthermore, it allows for the recording and analysis of work data, providing a reference for subsequent operations and helping to continuously optimize the work process and improve work efficiency.

The control terminal is used to set operating parameters, receive image data transmitted by the camera detection system, analyze rust removal and spraying effects, issue control commands, and record and analyze operating data. Operators input operating requirements through the control terminal, including sandblasting pressure, spraying flow rate, and spraying speed parameters. The control terminal calculates the corresponding control signals based on the input operating parameters. The sensor module, including a pressure sensor, an angle sensor, and a flow sensor, is used to monitor the operating parameters of sandblasting pressure, sandblasting angle, and spraying flow rate in real time and transmit the data to the control terminal.

The actuator control module is connected to the delivery pump of the sandblasting system and the oil spraying system, the drive device of the rotating structure, and the spraying pump actuator of the spraying system. After receiving the control signal from the control terminal, the actuator control module converts it into a corresponding drive signal to control the action of the actuator. The camera detection module captures images of the inner surface of the oil storage tank, converts them into electrical signals, and sends them to the image processing equipment through the signal transmission line. The image processing equipment processes and analyzes the images, extracts information on rust removal and spraying effects, and sends the information to the control terminal.
