PNEUMOACOUSTIC ATOMIZER OF A LIQUID Russian patent published in 2005 - IPC

FIELD: agriculture; devices for an atomization of a liquid.

SUBSTANCE: the invention is pertaining to the field of agriculture, in particular, to devices for an atomization of a liquid and may be used in the spraying equipment used for chemical protection of plants, in fog generators for a sheltered ground, at decontaminating treatment of livestock barns and animals. The pneumoacoustic atomizer of a liquid has a body of a nozzle, a rod-type emitter coaxially located in the body of the nozzle in the shut-type bearings and fixed to prevent its axial movement by a retaining ring. On the bush there is a compressed air feeding union enveloping the body of the nozzle and fixed by a retaining nut. Such a junction forms an air duct of the ring-type form, which through the union and uniformly distributed holes in the body of the nozzle is connected to a compressed air supply system. A concentric nozzle with its the conical part enveloping the body of the nozzle with a backlash, is connected to a liquid supply system by the union and braced to the bush by a sleeve nut. On the end of the rod-type emitter protruding beyond the shear of the nozzle body there is a fixed resonator of the acoustic vibrations. In the resonator cavity there is an elastic component protected by a high-wear-resistant reflective washer mounted with a backlash in the resonator. The offered design of the pneumoacoustic atomizer ensures uninterrupted operation, and also retention of a strictly directional and whirling a finely dispersed cloud of an aerosol increasing the aerosol capability to penetrate deep into a volumetric crown, ensures the address hit of drips on the elements of plants and reduced losses of an aerosol liquid particles to a minimum with a more uniform distribution of the drips on the treated object and so increasing efficiency of the liquid atomization.

EFFECT: the invention ensures increased efficiency of the liquid atomization.
