ACOUSTIC NOZZLE Russian patent published in 2017 - IPC B05B1/26 B05B1/34 B05B17/04 

FIELD: machine engineering.

SUBSTANCE: nozzle comprises a hollow body with a nozzle and a central core. The body is provided with a channel for liquid supply and has coaxial bushing rigidly connected thereto and provided with the nozzle secured in its lower part made in the form of a cylindrical two-stage bushing. The upper cylindrical stage of the bushing is connected by means of a threaded joint with central core coaxial thereto having a central hole and installed with an annular gap relative to the inner surface of the cylindrical bushing. The annular gap is connected to at least three radial channels made in the two-stage bushing connecting it with an annular cavity formed by the inner surface of the bushing and the outer surface of the upper cylindrical stage. The annular cavity is connected to the body channel for liquid supply. A sprayer made in the form of a truncated cone is rigidly fixed to the central core, in its lower part. The sprayer is made in the form of a truncated cone coaxial to the central hole of the core and fixed by its upper base to the base of the central core cylinder. A splitter is secured to the lower base of truncated cone by means of at least three spokes. The splitter is made in form of end round plate, the edges of which are bent towards the annular gap. There are helical grooves provided on outer side surface of the truncated cone. In the splitter which is fixed to the lower base of truncated cone by means of at least three spokes and made in the form of the end round plate, the edge of which is bent towards the annular gap, a throttle opening is made axially symmetrically to the central hole of the central core. An outer continuous diffuser is coaxially fixed to the central core rigidly coupled with upper the cylindrical stage of the two-stage nozzle bushing, in order not to cover the outlet section of the annular gap connected to at least three radial channels made in the two-stage nozzle bushing.

EFFECT: increased efficiency of liquid fine dispersion.
