Abstract

The invention relates to an acoustic vortex ultrasonic cleaning device. The acoustic vortex ultrasonic cleaning device comprises an ultrasonic signal generation and control system, a power amplification system and a cleaning system. A platform and N independently-driven electroacoustic transducers are arranged in a cleaning tank of the cleaning system. The N independently-driven electroacoustic transducers are respectively arranged on the side walls of the cleaning tank to form a group of ultrasonic generation arrays in an annular or focusing arrangement mode. After the transducers work, a superposed vortex sound field can be generated in the cleaning tank. Vortex waves carry the axial orbital angular momentum, and the orbital angular momentum can be transmitted to the fluid in the cleaning tank to drive the fluid to rotate, so that the flowing speed of the fluid in the cleaning tank can be remarkably increased, and a dirt layer can be easily stripped off. Particularly, the independently-driven electroacoustic transducers can be additionally arranged at the bottom and the top (a cleaning tank cover) of the cleaning tank correspondingly to form three groups of orthogonal ultrasonicarrays together with the side wall transducers, and the rotation control dimension of the fluid can be expanded from one dimension to three dimensions through a signal control terminal, so that the cleaning effect is further enhanced.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic cleaning, and relates to an ultrasonic cleaning device based on an acoustic vortex. Background technique [0002] The principle of ultrasonic cleaning is to use the cavitation, acceleration and direct flow effect of ultrasonic waves in the cleaning tank to have direct and indirect effects on liquid and dirt, so that the dirt layer is dispersed, emulsified, and peeled off, so as to achieve the purpose of cleaning. Compared with traditional manual cleaning, high-pressure water jet cleaning, organic solvent cleaning and other methods, ultrasonic cleaning has the characteristics of non-destructive and efficient, easy to automate, and strong decontamination ability. For precision components or complex workpieces, ultrasonic cleaning is the only cleaning method that can meet their special technical requirements. [0003] Common ultrasonic cleaning techniques utilize single or multiple ultrasonic tra...
