ACOUSTIC HEAD FOR NOZZLES FOR SPRAYING LIQUIDS WITH PARABOLIC SWIRLER Russian patent published in 2018 - IPC B05B17/04 

FIELD: machine engineering.

SUBSTANCE: acoustic head for nozzles for spraying liquids comprises a body with branch pipes for supply of a spraying liquid and a spraying agent. Inside the body, there is a generator of acoustic oscillations in the form of a nozzle and a resonator made in the form of an audio generator formed by a resonator of the helmholtz resonator. A hollow rod is inside the body axially symmetrical thereto and serving to form a produced flare of sprayed liquid entering through a hollow rod channel to an auger sprayer. The auger sprayer is rigidly fixed on the end of the hollow rod and serving to form liquid film closing an outlet of the sound generator. A parabolic swirler is fixed in the lower part of the screw sprayer body.

EFFECT: improved efficiency of liquid spraying.
