Description
Technical Field
[0001] This utility model relates to the technical field of anti-corrosion spraying equipment for petrochemical pipelines, specifically an anti-corrosion spraying equipment for petrochemical applications. Background Technology
[0002] The petrochemical industry is closely related to pipelines, which are key facilities for transporting petrochemical products, undertaking the long-distance transport of oil, gas, chemical raw materials, and products. Because pipelines are in prolonged contact with corrosive media, corrosion is a significant hidden danger in pipeline operation, making corrosion prevention measures crucial. Anti-corrosion coatings effectively isolate the pipeline surface from the external environment, preventing corrosion caused by moisture, salt, acidic gases, and other factors. Common anti-corrosion coatings include epoxy resin coatings, polyurethane coatings, and polymer coatings. Anti-corrosion spraying equipment, as an important tool for coating applications, is widely used for external corrosion protection of pipelines. Common spraying equipment includes high-pressure air sprayers, electrostatic sprayers, and thermal sprayers. High-pressure air sprayers use air pressure to spray coating onto the pipeline surface, suitable for large-area coating; electrostatic sprayers utilize electrostatic attraction to improve coating adhesion and reduce waste; thermal sprayers heat the coating to a molten state before spraying, resulting in coatings with higher wear resistance and corrosion resistance. The application of these spraying devices not only improves the uniformity and adhesion of the coating but also effectively extends the service life of pipelines, ensuring the safe and stable operation of petrochemical pipeline systems.
[0003] In some large-scale pipeline spraying operations, spraying robots are usually used to complete the work. However, the existing equipment has a simple structure and is located at the bottom of the pipeline during spraying, which results in uneven spraying. In addition, dust may accumulate inside the pipeline, and the existing equipment is difficult to complete the dust removal work, which increases the labor intensity of users and reduces the practicality of the equipment.
