CENTRIFUGAL WIDE PATTERN NOZZLE Russian patent published in 2018 - IPC B05B1/34 

FIELD: separation; mixing.

SUBSTANCE: invention relates to devices for spraying of liquids, solutions. Centrifugal wide pattern nozzle comprises a body with a vortex chamber and a nozzle insert. Body is provided with an inlet fitting having a hole coaxial with the inlet cylindrical chamber, a vortex chamber coaxial with the inlet chamber and made in the form of a cylindrical sleeve which has at least three tangentially arranged holes on the side surface, the axes of which are tangential to the vortex chamber, namely, there is a multi-channel tangential entry. Nozzle insert with an outer diameter D₁ is located coaxially with the vortex chamber_. there are three calibrated holes in the insert, arranged in series and coaxial to each other and to cylindrical surface of the vortex chamber: conical hole with diameter D of truncated cone lower base, central cylindrical hole with diameter d₂ and an outlet conical hole with a diameter d₃ truncated cone lower base. Diameter d₂ of the central cylindrical hole of the nozzle insert is equal to the diameter of the truncated cone upper base of the conical hole and the diameter of the truncated cone upper base of the output conical hole. Nozzle is further provided with a water filter for cleaning from mechanical impurities, which is made in the form of a ring, coaxial with the vortex chamber cylindrical surface and adjacent without gaps to its outer cylindrical surface, overlapping holes tangentially located in the vortex chamber, and the filter can be fastened by means of a clamp or the filter is made in the form of a sleeve, which is fitted without gaps on the vortex chamber outer surface.

EFFECT: technical result: increased spray efficiency.
