KOCHETOV'S CENTRIFUGAL ATOMISER WITH ACTIVE SPRAY GUN Russian patent published in 2015 - IPC F23D11/04 B05B1/34 

FIELD: technological processes.

SUBSTANCE: invention relates to liquid and solution spraying devices and can be used in engine building, in the chemical and food industries. A centrifugal atomiser with an active spray gun includes a housing, in which a screw is pressed, and a liquid supply nozzle; the housing consists of two coaxial cylindrical sleeves attached to each other: a sleeve of a larger diameter and a sleeve of a smaller diameter; with that, inside the sleeve of the smaller diameter, coaxially to it, there located is a screw rigidly attached to its inner surface, for example pressed into it; besides, the outer surface of the screw represents a spiral groove, and inside the screw there is a hole with a screw thread, and in the sleeve of the larger diameter, coaxially to it, there located is a nozzle rigidly fixed in it, for example by means of a threaded connection, through a sealing gasket; with that, inside the nozzle there coaxially made is a cylindrical hole changed over into an axisymmetrically located diffuser that is connected to a cylindrical chamber formed with the inner surface of the sleeve of the smaller diameter and the end surface of the screw, and to the end surface of the sleeve of the smaller diameter there attached is an active spray gun of a rod type with blades, which is made in the form of a flattened tetrahedron attached to the end surface of the sleeve of the smaller diameter, the ribs of which are represented by rods with blades with limit stops, which are fixed on them so that there can be a possibility of their rotation against vortex flows leaving the atomiser screw; with that, the ribs of the tetrahedron base are also connected with rods to the blades and limit stops fixed on them.

EFFECT: improvement of spraying efficiency.
