Rust-removing cleaning device for ultrasonic pulse water jet pipe wall

Abstract

The invention relates to a rust-removing cleaning device for an ultrasonic pulse water jet pipe wall, which is used for cutting the pipe wall and removing a surface coating, corrosion, scale formation and the like and comprises a vortex pulse resonance jet spray head mechanism, a transplanting lifting track mechanism, a high-pressure water supply mechanism and an ultrasonic wave supply mechanism,wherein the vortex pulse resonance jet spray head mechanism is arranged on the transplanting lifting track mechanism; and the high-pressure water supply mechanism and the ultrasonic wave supply mechanism are respectively connected with the high-pressure water input end and the ultrasonic input end of the vortex pulse resonance jet spray head mechanism through a high-voltage water input hose and apulse signal cable. By adopting the pulse jet technology, the invention generates powerful pulse jet, improves the energy conversion efficiency, greatly reduces the use pressure, reduces the manufacturing cost and the maintenance and use expense, saves energy and reduces the emission. A micro air cooler provides cooling compressed air and an air source required for the swing of a spray head; in addition, the invention has the advantages of strong maneuverability, high efficiency, safety and reliability.

Description

technical field [0001] The invention relates to an ultrasonic pulse water jet pipe wall derusting and cleaning device for cutting pipe walls and removing surface coatings, rust and oxide scales. Background technique [0002] High-pressure water jet technology and equipment are widely used in industrial cleaning, cutting, deburring and surface coating peeling. In general industrial cleaning, rust removal, and scale removal processes, most of them use continuous pure water jets. The pressure of high-pressure water required is generally 150-250Mpa, and the removal of some hard metal coatings, oxide scales and deburring requires continuous high-pressure jets of pure water up to 350-420Mpa to complete. Especially in the internal and external cleaning of large pipe walls, rust removal, paint removal and scale removal, there is no reliable way. [0003] In the current large-scale pipe wall rust removal and scale removal processes in the aerospace industry, petrochemical industry,...

AI Technical Summary

Problems solved by technology

[0005] 1. Manual grinding or pickling process is used, which has low efficiency, low processing quality and pollutes the environment;

[0006] 2. The structure of the ultra-high pressure water jet cleaning system is complex, the water spray system is expensive and heavy, the use conditions are cumbersome, and the energy consumption is high;

[0007] 3. At present, there is still no efficient pipe wall cleaning and derusting actuator, resulting in low production efficiency, high energy loss, and extremely low efficiency.
