PNEUMOACOUSTIC LIQUID ATOMIZER Russian patent published in 2005 - IPC

FIELD: agricultural engineering.

SUBSTANCE: invention relates to devices for atomizing liquids of different viscosity and it can be used for producing highly dispersed aerosols for chemical protection of plants, in fog generators for sheltered grounds and decontamination of live stock barns and animals. Proposed pneumoacoustic liquid atomizer has nozzle housing, rod-type radiator arranged coaxially in nozzle housing in closed-type bearings and fixed from axial displacement by lock ring. Unit to deliver compressed air is installed on bushing enclosing nozzle housing and fixed by locknut. Such connection forms ring-shaped air channel communicating with compressed air supply system through union and holes uniformly distributed in nozzle housing. Concentric nozzle enclosing, by taper part, nozzle housing with clearance is connected with liquid feed system by union and is pressed to bushing by union nut. Blades are arranged in space of gas jet radiator formed by inner space of nozzle housing at its outlet and rod radiator, blades being secured on rod radiator. Acoustic vibration resonator is secured on end of rod radiator projecting beyond nozzle housing cut. Flexible element mounted in resonator space is protected by wear resistant deflecting washer with cross cuts which is installed in resonator with clearance.

EFFECT: provision of reliability and faultlessness in operation and formation of perfectly aimed jet, thus increasing utilization factor.
