ACOUSTIC NOZZLE FOR SPRAYING SOLUTIONS Russian patent published in 2018 - IPC B05B1/00 

FIELD: liquids spraying or atomizing devices.

SUBSTANCE: invention relates to the liquids, solutions spraying devices. In the solutions spraying acoustic nozzle containing housing with the sprayed liquid and spraying agent supply branch pipes, inside which the acoustic oscillations generator is arranged in the form of nozzle and resonator, made in the form of formed by the Helmholtz resonator sound generator, made in the form of at least one spherical cavity located in the conical surface ring wall, which through the calibrated gaskets is connected to the housing, at that, by the calibrated hole the sound generator spherical cavity is connected to the annular gap formed by the housing end faces and ring with the side conical surface, made on the hollow rod, which is located inside the housing axially symmetric thereto, and serves for the sprayed liquid generated torch formation, coming through the hollow rod channel 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, 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 made to control the generated frequency of the acoustic vibrations by adjusting the width of the annular gap, formed by the end faces of the housing and the ring, by installing between the housing and the ring with a conical surface of calibrated gaskets, the thickness of which corresponds to a specified frequency of acoustic vibrations, in the lower part of the housing of the screw atomizer, an additional disc atomizer consisting of a thread bush with a central hole connected to the plane of the rod by means of a calibrated hole, rigidly connected to threaded bushing with central hole upper disc, and the lower solid disk connected to the upper disc by means of at least three fastening elements with formation of the throttling gap between the discs.

EFFECT: increase in the liquid spraying efficiency.
