VORTEX ATOMIZER WITH A VORTEX UNIT Russian patent published in 2018 - IPC B05B17/04 

FIELD: devices for spraying liquids.

SUBSTANCE: invention relates to devices for spraying of liquids, solutions. Vortex acoustic atomizer with a vortex unit 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 which there is a conical chamber for supplying liquid to the nozzle. Vortex atomizer also comprises an acoustic unit. Nozzle made in the form of an inverted barrel is connected to the cylindrical sleeve, in its lower part, in bottom of which there is a turbulent air flow swirler with at least two inclinations 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 resonant conical sleeve consisting of sections with resonant holes connected to the cavity for supplying compressed air or gas. Cavity for supplying compressed air or gas is located between the inner surface of the cylindrical sleeve and the hollow resonant conical sleeve which is connected by means of inclined cylindrical holes to the mixing chamber of the nozzle. Cavity for supplying compressed air through the resonant holes is connected to an additional resonant chamber made in the form of an annular recess in the cylindrical sleeve, separated from the cavity by the annular partition, in which resonant bushings are fixed.

EFFECT: increased spraying efficiency due to spray cone increasing.
