VORTEX RESONANT NOZZLE Russian patent published in 2018 - IPC B05B17/06 B05B1/34 

FIELD: devices for spraying or atomizing liquids.

SUBSTANCE: invention relates to devices for liquids, solutions spraying. Vortex resonant nozzle comprises a housing with a swirl chamber and a nozzle, the housing is in the form of a supply fitting with a central hole and rigidly connected thereto and a coaxial cylindrical sleeve with an internal thread and an expansion chamber coaxial to the housing, in its lower part is connected to the sleeve by means of a threaded nozzle, made in the form of an inverted glass, in the bottom of which there is a turbulent swirler of the liquid flow with at least two inclusions to the axis of the nozzle in the form of cylindrical openings, which are located in the end surface of the nozzle, where a central cylindrical throttle opening is also connected to the mixing chamber of the nozzle, in series connected to the diffuser outlet chamber, a diffuser is provided in the diffuser outlet chamber in the form of at least three spokes, each of them is fixed by one end to the outer surface of the diffuser outlet chamber, perpendicular to the surface forming it, 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, and the body of revolution itself is located in the lower part behind the cutoff of the diffuser outlet chamber, a diffuser is attached to the end surface of the cylindrical sleeve coaxial with the body, coaxial to the diffuser chamber, the cut surface of which lies in a plane below the surface of the body of rotation of the dissector, 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 the axis on which the body of rotation 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 output chamber, the surface of the body of rotation made in the form of a ball mounted on the axis with the possibility of rotation is perforated, to the surface of the body of rotation, made in the form of a ball mounted on an axis, for example in the form of segments of helical blades, on the inner surface of the central cylindrical throttle opening located in the end surface of the nozzle, screw grooves are provided for performing additional twisting of the liquid flow, in the body of revolution, whose axis coincides with the axis of the diffuser outlet chamber, and the body of rotation itself is located in the lower part behind the cutoff of the diffuser outlet chamber, resonant recesses are made in the form of a cylindrical surface of different diameters and lengths, performing the functions of Helmholtz resonators, their dimensions are determined by the necessary pulsation frequency of the liquid flow to increase the fineness of the sprayed flame. To the diffuser, whose axis coincides with the axis of the diffuser outlet chamber, triangular profile ring is coaxially attached at its output with resonant recesses at an angle of 45° to the nozzle axis, and coaxially with its outlet hole, a ring with a perforated disk at the outlet is attached to it, in the lateral surface of which at an angle of 90° to the axis of the injector, resonant recesses are formed in the form of a cylindrical surface of different diameters and lengths, performing the functions of Helmholtz resonators, their dimensions are determined by the necessary pulsation frequency of the liquid flow to increase the fineness of the sprayed spray of the injector.

EFFECT: increasing spraying efficiency due to spray cone increasing.
