Abstract

The invention relates to a complex frequency emulsified fluid power sounding device. A spraying nozzle is arranged on one side in a sleeve; a bracket opposite to the spraying nozzle is arranged on the other side of the sleeve; at least two spraying openings are machined in the spraying nozzle; an overflowing hole is machined in the middle of the bracket; reeds which are in one-to-one correspondence with the spraying openings are arranged on the periphery of the overflowing hole; each reed faces the jet direction of the corresponding spray opening; the length or / and the thickness of each reed is different from the length or / and the thickness of the adjacent reed. The complex frequency emulsified fluid power sounding device can produce a plurality of different sound wave frequencies, is favorable for the emulsifying and the mixing of liquid; the reeds start to oscillate more easily, and are not easily broken within a long working time; the complex frequency emulsified fluid power sounding device can be directly connected between pipelines, and is high in emulsifying and mixing efficiency, stable in operation, simple in structure, low in cost, and suitable for engineering application.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic mixing or emulsification, in particular to a multiple-frequency emulsification hydrodynamic sounding device which uses fluid as a power source to realize deep emulsification or mixing. Background technique [0002] At present, the reed whistle, as a fluid dynamic sounding device for acoustic cavitation amplification from laboratory effects to engineering applications, has received extensive research and attention on its application effects. The jet liquid sheet excites the reed to vibrate to generate sound waves or ultrasonic waves. The liquid passes through the nozzle channel. Due to the expansion of the cross section, more cavitation bubbles are formed in the low-pressure area. Under the action of the reed vibration and sound waves, the cavitation bubbles grow and collapse. Cavitation is generated, and the high temperature and high pressure generated during the cavitation process together wit...
