ACOUSTIC SPRAYER BY KOCHETOV Russian patent published in 2012 - IPC F23D11/34 B05B17/04 

FIELD: machine building.

SUBSTANCE: acoustic sprayer includes housing with acoustic generator arranged inside the housing in the form of nozzle and resonator, air and fluid supply branch pipes; housing is provided with a collar on one side of which there made is gas supply nozzle, and on the other side of the collar there fixed axisymmetrically to the housing is cylindrical sleeve rigidly attached to conical nozzle, and inside cylindrical sleeve there fixed is case with throttle holes the axes of which are parallel to the housing axis, as well as resonator rod is attached to the case coaxially to the housing; resonator disc is rigidly installed through central hole and a screw on free end of resonator rod opposite the section of conical nozzle with an axial gap; at that, in resonator disc there located are at least three blind holes being the part of acoustic generator of ultrasonic frequency range, which is made in the form of a conical nozzle coaxial to the housing and has annular throttle hole with outer diameter d_c, which is formed with the nozzle section and resonator rod with diameter d_rod, and sprayed fluid is supplied through the branch pipe located perpendicular to the housing axis to annular cavity formed with the casing and external surface of the nozzle; at that, one end of casing is solid and connected to the housing, and in the other end enveloping the conical nozzle there made are throttle holes that are coaxial to annular throttle hole with outer diameter d_c.

EFFECT: higher spraying efficiency and operating reliability.
