KOCHETOV CENTRIFUGAL VORTEX NOZZLE Russian patent published in 2017 - IPC B05B1/34 B05B1/26 

FIELD: machine engineering.

SUBSTANCE: centrifugal vortex nozzle comprises case with swirling chamber and nozzle. The casing is made in form of the union with hole for liquid supply from main line and rigidly connected with it cylindrical coaxial sleeve with external thread. Coaxial to the chassis in its lower part connected by sleeves with inner thread nozzle, made in the form of a centrifugal flow swirler in the form of a deaf cylindrical insert. Insert is made with at least three tangential inlets in the form of cylindrical holes. Liner is part of nozzle and coax installed and aligned towards the centrifugal swirler. In the face of the centrifugal swirler solved tapered bore, the coaxial cylindrical swirler inserted outlandish. Swirler ring is mounted in a cylindrical chamber housing with the formation of annular cylindrical chamber for liquid supply to the tangential inlets centrifugal swirler. Tangential inlets are made in the form of canals, tangentially located to the inner surface of the deaf cylindrical insert. In the centrifugal swirler, the intensifier is installed in a centrifugal twisting fluid flow, which is executed in the form of stock. One end of the rod is attached to the cylindrical surface of a round insert outlandish transformed using screws. At the other end of the rod mounted a second swirl ring, made in the form of a flow sleeve with external screw thread with large pitch of trapezoidal profile and anchored by tapping on the rod with conical radome. Axle chassis nozzles, to its outlet at the bottom of the rigidly attached konfuzor, having on the inner surface threaded with a major step of trapezoidal profile and has a direction opposite twist intensifier fluid flow. Coaxial intensifier of twisting fluid flow with conical radome to confuser the conical flow divider is rigidly attached. The upper perforated part of the flow spreader cone passes inside the surface of the confuser is fitted by perforation. Konfuzor's surface is completed with perforations. The vertex of the perforated part of the spreader cone touches the vertex of the fairing cone. A conical flow spreader is rigidly attached to the confuser coaxially to the intensifier. The upper perforated part of the flow spreader cone passes inside the surface of the confuser is fitted by perforation. The solid part of the cone is designed in the form of rings, located perpendicularly to its axis and is rigidly connected to the perforated part of the cone of chopper.

EFFECT: higher efficiency of spraying by means of increases spray cone.
