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

Abstract RU 2644860 C1

FIELD: separation; mixing.

SUBSTANCE: invention relates to devices for spraying of liquids, solutions. Acoustic atomiser for spraying solutions, comprising a body with pipes for supplying a spraying liquid and a spraying agent, within which an acoustic 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, which is connected to the body via calibrated gaskets, the spherical cavity of the sound generator being connected by a calibrated hole with an annular slot formed by the end faces of the body and the ring with a lateral conical surface formed on a hollow rod which is located inside the housing, axially symmetrical thereto, and serves to form the generated spray of the spray liquid entering through the channel of the hollow rod to a screw atomiser, rigidly fixed to the end of the hollow rod and serving to form a liquid film covering the output of the sound generator formed by the Helmholtz resonator, and the ring with a lateral conical surface formed on the hollow rod is arranged to be fixedly movable along the axis of the body by means of a threaded connection that connects the body to the ring via calibrated gaskets, wherein the Helmholtz resonator is configured to control the generated frequency of the acoustic vibrations by adjusting the width of the annular gap defined by the end planes of the body and the ring by installing the calibrated gaskets between the body and the ring with a conical surface, the thickness of said gaskets of which corresponds to a predetermined frequency of acoustic vibrations, in the lower part of the body of the screw atomiser there is an additional disc atomiser consisting of a threaded sleeve with a central hole, connected to the cavity of the rod by means of a calibrated hole, an upper disc rigidly connected to the threaded sleeve with a central hole, and a lower solid disc connected to the upper disc by means of at least three fasteners to form a throttling gap between the discs.

EFFECT: technical result is increased efficiency of spraying of liquids.
