ULTRASONIC OSCILLATING SYSTEM (VARIANTS) Russian patent published in 2018 - IPC B06B1/06 

FIELD: technological processes.

SUBSTANCE: using: for the separation of dispersed materials. Summary of invention is thatin the first variant, an ultrasonic oscillating system contains a working waveguide, piezoelectric transducer comprising a radiating and reflecting plates connected with piezoceramic plates between them connected with a clamping element, as well as a counterweight resonator, having the same frequency of ultrasonic vibrations with a transducer, while the latter is tightly connected through the working waveguide with the said resonator, acoustically contacting with the side surfaces of the working waveguide. According to the second variant, the ultrasonic oscillating system differs from the first one in that instead of the counterweight resonator, a similar transducer with the same frequency of ultrasonic vibrations is acoustically connected to the first piezoelectric transducer through the working waveguide.

EFFECT: technical result: increasing the operational reliability ofultrasonic oscillating system in devices designed for sifting fine powders.
