KOCHETOV SWIRL ATOMIZER Russian patent published in 2017 - IPC B05B1/26 B05B1/34 F23D11/04 

FIELD: machine engineering.

SUBSTANCE: swirl atomizer comprises a housing with an auger installed coaxialy in the lower housing part, and a connecting pipe installed in the upper housing part and fitted by a cylindrical hole with a diffuser being axisymmetrical to the housing and the connecting pipe, and the auger is pressed-in the housing to form a conical chamber located above the auger coaxially to the diffuser and coupled to it sequentially. The auger is made solid, and theits outer surface is two series-connected surfaces, one of which is at least a single-threaded screw groove with right or left thread and is located inside the housing, and the second surface is made smooth in the form of a rotary body which is axisymmetrically connected with a spraying disk located perpendicular to the axis of the housing, and protrudes beyond the end surface of the lower part of the housing. Both a straight line and a curved line of the n-th order can be used as the line forming this surface, the surface of the spray disc protruding beyond the end surface of the lower part of the housing is made deflected towards the housing bottom and has on the peripheral part the radial cuts alternating with the solid part of the surface of the spraying disk, the spraying disk is displaced along the axis of the nozzle down from the smooth surface of the auger rotary body, connected to the helical surface of the auger by a value h, depending on the sprayed liquid viscosity and is connected to the auger by the rod located axially to the auger, and a diffuser is attached to the end power surface of the nozzle, covering the spraying disc. At the top of the diffuser, at least three ejection openings are made, a divider is attached to the diffuser cut, made of coaxially arranged, perforated conical shells, external and internal, the space between which is filled with a fine-meshed screen. The apices of the conical surfaces of the shells are directed away from the diffuser, and in the lower part of the divider the spherical perforated segment is fixed in such a way that the apex of the external conical shell coincides with the center of the spherical surface of the perforated segment.

EFFECT: increased efficiency of dispersion.
