Abstract

The invention relates to an ultrasonic pulse resonance jet rotary spray-head device which comprises an ultrasonic transducer and a spray head, wherein a longitudinal pulse jet inlet is drilled in an ultrasonic transducer body, the ultrasonic transducer body is rotatably installed on the central shaft of the transducer, a high-pressure rotary sealing device is arranged between the central shaft ofthe transducer and the ultrasonic transducer body, an axial high-pressure water channel communicated with the longitudinal pulse jet inlet is drilled in the central shaft of the transducer, and an ultrasonic transduction vibrator is arranged outside the central shaft of the transducer; and an oscillation cavity is arranged in the shell of the spray head, a plurality of nozzles are arranged at thelower end of the shell of the spray head, a multi-head amplitude-changing rod is arranged in the oscillation cavity, and a plurality of miniature amplitude-changing heads are fixedly connected onto the multi-head amplitude-changing rod. The design of the rotary ultrasonic transducer and the spray head is adopted by the invention, the oscillation cavity is arranged in the shell of the spray head, and the multi-head amplitude-changing rod is arranged in the oscillation cavity, thereby improving the energy conversion efficiency, increasing the cleaning width and area of the ultrasonic pulse resonance jet rotary spray-head device and greatly improving the cleaning efficiency of the ultrasonic pulse resonance jet rotary spray-head device.

Description

technical field [0001] The invention relates to an ultrasonic pulse resonant jet device for industrial cleaning, surface coating stripping, deburring, rust removal, paint removal or steel surface descaling by using ultrasonic oscillating pulse jet, specifically an ultrasonic pulse resonant jet rotary nozzle device . Background technique [0002] High-pressure water jet technology and equipment is a high-tech developed in the 1970s and widely used in industrial cleaning, cutting, deburring, surface coating peeling, rust and paint removal, etc. After decades of rapid development, several major fields such as pure water jet, abrasive water jet, unsteady water jet and ultrasonic water jet have been formed. In general industrial cleaning, most of them use continuous high-pressure pure water jets. In the fields of rust removal, paint removal and surface coating peeling, the pressure of high-pressure water required by pure water high-pressure water jets is generally 150~250Mpa, w...

AI Technical Summary

Problems solved by technology

[0006] 1. The cleaning effect of the existing single-nozzle vortex nozzle is better, which can increase the impact force and cleaning effect by about 5-7 times. However, due to its narrow cleaning width and small cleaning area, the cleaning efficiency of the single-nozzle vortex nozzle lower;

[0007] 2. Although the existing pulse jet rotary nozzle has improved its cleaning width and area, due to the defect of the mixing chamber structure of its pulse jet, the nozzle outlet is far away from the multi-head horn, and the ultrasonic attenuation energy loss is large, which cannot form a stable The pulse oscillating jet has poor striking force and cleaning effect, and the cleaning efficiency is still low
