CENTRIFUGAL ATOMIZER Russian patent published in 2018 - IPC B05B3/00 

FIELD: devices for spraying or atomizing liquids.

SUBSTANCE: invention relates to devices for liquids, solutions spraying. In a centrifugal nozzle comprising a housing with a swirl chamber and a nozzle insert, the housing is provided with an inlet pipe having an opening coaxial with the inlet cylindrical chamber, swirl chamber located coaxially with respect to the inlet chamber and made in the form of a cylindrical beaker having at least three tangentially disposed openings on the side surface, its axes are tangentially relative to the swirl chamber, and a nozzle insert made of solid materials is arranged coaxially with the swirl chamber, inside the liner, there are successively arranged and coaxial to each other and a cylindrical surface of the swirl chamber, two calibrated holes: a cylindrical hole and a conical hole that serves as a diffuser, that increases the angle of the cone at the top of the spray of the liquid, a screw with helical blades is axially symmetric and coaxially attached to the bottom of the cylindrical glass of the swirl chamber from the side of the nozzle liner, the direction of the helical screw worms axially symmetrically and coaxially attached to the bottom of the cylindrical cup of the swirl chamber coincides with the direction of the twist of the flow in the swirl chamber, or back to the direction of the flow twist, at that the spiral blades of the screw are located on it with an increase in their outer diameter away from the bottom of the cylindrical beaker, fitting in this way into the conical surface bounding them, besides the perforated divider in the form of a diffuser is attached to the conical aperture coaxially and axially symmetrically to the nozzle insert of the swirl chamber, at that the conical surface forming the diffuser and the conical surface defining the spiral blades of the screw are made equidistant.

EFFECT: higher efficiency of spraying.
