VORTEX ACOUSTIC NOZZLE Russian patent published in 2018 - IPC B05B17/04 B05B1/26 B05B1/34 

FIELD: devices for spraying liquids.

SUBSTANCE: invention relates to devices for spraying of liquids, solutions. Vortex acoustic nozzle comprises a body made in the form of a supply fitting with a central hole and rigidly connected to it coaxially with a cylindrical sleeve. In the sleeve there is a conical chamber for supplying liquid to the nozzle. Nozzle also contains an acoustic unit. Nozzle made in the form of an inverted glass is connected to the cylindrical sleeve, in its lower part. In the bottom of the cup there is a turbulent swirler of the liquid flow with at least two entries inclined to the axis of the nozzle in the form of cylindrical holes and a central cylindrical throttle opening connected to the mixing chamber of the nozzle, in series connected to the diffuser outlet chamber. Acoustic unit is located coaxially with the conical chamber and is made in the form of a coaxially located hollow resonance conical sleeve consisting of sections with resonant holes connected to the cavity for supplying compressed air or gas. Cavity is located between the inner surface of the cylindrical sleeve and the hollow resonance conical sleeve which is connected by means of inclined cylindrical holes with the mixing chamber of the nozzle. Cavity with the supply of compressed air through resonant holes is connected to an additional resonant chamber, which is in the form of an annular recess in a cylindrical sleeve, separated from the cavity by an annular partition in which resonance sleeves are fixed.

EFFECT: increasing spraying efficiency due to spray cone increasing.
