Matching device of ultrasonic resonance frequency

Abstract

The invention discloses a matching device of ultrasonic resonance frequency. The matching device of ultrasonic resonance frequency comprises a water taking tank, ultrasonic vibrators, an ultrasonic control circuit, an X-axis driving mechanism, a Y-axis driving mechanism and a shell, wherein the ultrasonic vibrators are installed on the four side surfaces and the bottom surface of the water takingtank, the ultrasonic control circuit is used for adjusting the ultrasonic frequency emitted by the ultrasonic vibrators, and foldable structures are arranged at the joints of the four side surfaces and the bottom surface of the water taking tank; the X-axis driving mechanism is used for driving the two side surfaces, located in the X-axis direction, of the water taking tank to be expanded or contracted by virtue of the foldable mechanisms, the Y-axis driving mechanism is used for driving the two side surfaces, located in the Y-axis direction, of the water taking tank to be expanded or contracted by virtue of the foldable mechanisms, and the opening port of the water taking tank is outward. The device can be used for carrying out multi-frequency-band cleaning or crushing on a trial sample,meanwhile, the size of the water taking tank can be adjusted, so that the incident wave and the reflected wave of the ultrasonic wave are enabled to be subjected to in-phase interference resonance, and then the trial sample crushing or cleaning effect is improved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic cleaning, in particular to an ultrasonic resonance frequency matching device. Background technique [0002] Ultrasonic crushing is the process of crushing materials using ultrasonic energy. The principle of crushing includes: the positive and negative alternating sound pressure field formed by the propagation of ultrasound in the medium exerts tension and compression force on the material particles in the medium, and frequent alternating stress can lead to fatigue and crushing of the particles; when the ultrasonic frequency is consistent with the resonance frequency of the material particles When the particle resonance is excited, the energy can be oscillated, causing the material particles to resonate and break; the ultrasonic cavitation makes the cavity (unsteady microbubble) form at the low pressure of the sound field, and the cavity collapse at the high pressure, and the cavity collapses. ...
