ACOUSTIC ATOMIZER FOR SPRAYING SOLUTIONS Russian patent published in 2018 - IPC B05B17/04 

FIELD: devices for spraying or atomizing liquids.

SUBSTANCE: invention relates to devices for liquids, solutions spraying. Acoustic nozzle for spraying solutions contains a housing with nozzles for supplying a spraying liquid and a spraying agent, inside of which an acoustic oscillation generator is arranged in the form of a nozzle and a resonator, made in the form of a sound generator formed by a Helmholtz resonator made in the form of at least one spherical cavity located in the wall of a ring with a conical surface that is connected to the body through calibrated gaskets. Spherical cavity of the sound generator is connected by a calibrated hole with an annular gap formed by the end planes of the housing and a ring with a lateral conical surface made on a hollow rod, that is located inside the shell axially to it and serves to form the resulting flare of the atomized liquid entering through the channel of the hollow rod to the screw atomizer, rigidly fixed at the hollow rod end and serving for the liquid film formation, overlapping the formed by the Helmholtz resonator sound generator output. Ring with a lateral conical surface is arranged to be fixedly movable along the axis of the housing by means of a threaded connection that connects the housing to the ring via calibrated gaskets. In the screw atomizer body lower part, an additional disc atomizer is attached, consisting of a threaded bushing with a central hole connected to the rod cavity by means of calibrated hole, rigidly connected to threaded bushing with central hole upper disc, and a lower solid disk connected to the upper disc by means of at least three fasteners to form a throttling gap between the discs, with an external diffuser coaxially attached to the lower portion of the nozzle body, and an internal perforated diffuser is attached to the conical surface of the screw diffuser in such a way that the exit cross-sections of the external and internal diffusers lie in the same plane, perpendicular to the axis of the screw diffuser, characterized by fixing coaxially the external diffuser to an additional flow divider, in the form of a cylindrical shell, where on the end part a perforated plate is attached to the end opposite the diffuser.

EFFECT: technical result of the invention is an increase in the spraying efficiency of liquid.
