SWIRL ATOMIZER Russian patent published in 2018 - IPC B05B1/34 B05B17/04 

FIELD: devices for spraying or atomizing liquids.

SUBSTANCE: invention relates to devices for liquids, solutions spraying. Swirl atomizer contains a body with a swirl chamber and a nozzle. Body is made in the form of a supply fitting with a central hole and rigidly connected to it and a coaxial cylindrical sleeve with an internal thread and an expansion chamber coaxial to the housing. Nozzle made as an inverted barrel is attached to the sleeve by the thread coaxially to the casing in its lower part. Cup bottom is provided with fluid flow turbulence swirler with, at least, two inclined feed cylinder holes inclined to the nozzle axis and made in nozzle face surface, where also a central cylindrical throttle opening is made connected to the nozzle mixing chamber, in series connected to the diffuser outlet chamber. In outlet diffuser chamber splitter is arranged made in form of, at least, three spokes. Each of spokes is secured by one end to outlet diffuser chamber outer surface perpendicular to its surface generatrices, and by the other end – in the surface of the body of rotation, for example, a ball whose axis coincides with the axis of the outlet diffuser chamber. Body of rotation itself is located in the lower part behind the cutoff of the outlet diffuser chamber. Diffuser is attached to the end surface of a cylindrical sleeve coaxial with the body, coaxial to the diffuser chamber. Cut surface of diffuser lies in a plane below the surface of the divider’s body of rotation. Divider is made in the form of two spokes, each of which is fixed at one end to the outer surface of the diffuser outlet chamber, perpendicular to the surface forming it, and the other – on an axis on which a rotating body is mounted with the possibility of rotation, made in the form of a ball, the center of which lies on the axis of the diffuser outlet chamber. Surface of body of revolution made in form of ball mounted on axis with possibility of rotation, is made perforated. In the cylindrical sleeve there is an acoustic unit made with a compressed air inlet in the form of a toroidal shell of rectangular cross section with resonance sleeves forming Helmholtz resonators connected by means of an inlet for the entry of compressed air with a cavity of the toroidal shell in which they are fixed. Compressed gas is discharged from the acoustic unit through the outlet throttling sleeves, which are located in the lower part of the acoustic unit and point toward the mixing chamber of the nozzle. To the surface of the body of rotation, made in the form of a ball and mounted on the axis with the possibility of rotation, elements are installed that rotate it, for example, in the form of segments of helical blades.

EFFECT: increased spraying efficiency due to spray cone increasing.
