TECHNICAL FIELD

[0001] The utility model relates to ultrasonic generator technical field, concretely is a kind of fluid ultrasonic generator. BACKGROUND

[0002] The homogenization of ultrasonic wave is mainly realized by cavitation and other physical effects in liquid, and is divided into two types according to the principle of ultrasonic generation: electric ultrasonic wave and fluid power ultrasonic wave. Although the electric ultrasonic wave has good homogenization effect, it needs to be installed with electric equipment, which is high in cost and energy consumption, and small in processing capacity. In the environment of corrosive or strong acidic substances, the electric components are easy to be damaged and have short service life, so it is not suitable for application in harsh chemical industry. The fluid power ultrasonic wave is composed of high-speed nozzle and feedback spring whistle according to Hartmann whistle principle, and the fluid power ultrasonic wave uses fluid (gas or liquid) as power to excite the vibration of spring whistle, so that the spring whistle and fluid medium resonate to emit ultrasonic wave.

[0003] At present, the fluid power ultrasonic wave needs high fluid power source in the nickel sulfate oxygen leaching section, and the energy conversion rate is low. The oxygen consumption is huge, and the cost of oxygen is high. The traditional spring whistle has small cavitation area, and the ultrasonic wave is strengthened in one direction, but the ultrasonic cavitation intensity is weak in the other direction, which causes poor ultrasonic effect. The fluid ultrasonic wave currently uses spring whistle fixed in two ways, including support point type and cantilever type. The support point type supports the wave node of the spring whistle vibration by supporting point, and the cantilever type is fixed at one end and can freely vibrate at the other end. The spring whistle is fixed and cannot be adjusted, and the vibration frequency is fixed, so the applicability is narrow. The conventional fluid ultrasonic wave needs larger fluid power source, and the energy conversion rate is low. The required gas amount is large, and the operation cost is high. The spring piece is easy to break in long-term vibration, which shortens the service life. Therefore, we propose a fluid ultrasonic generator. UTILITY MODEL CONTENTS
