SPRAY JET DISCHARGING DEVICE Russian patent published in 2020 - IPC B05B9/08 B05B7/24 

FIELD: machine building.

SUBSTANCE: sprayed jet ejection device comprises fan with impeller with possibility of rotation inside spiral casing (1), hydraulic motor (2), oil to which is supplied via hydraulic circuit (52), for actuation of impeller for creation of air flow, hydraulic pipeline for connection with source of liquid, wherein said pipeline comprises spray nozzles (17) for spraying liquid inside the ejected air flow to create a sprayed jet, and a support for mounting the fan, wherein the fan support comprises: U-shaped support base (20) with which spiral housing (1) is pivotally connected in two opposite points (21), (22), located on two arms "U" and forming an imaginary horizontal axis, around which helical casing (1) rotates to allow changing the inclination angle of ejected jet in vertical plane, in upward or downward direction; support post (19) with possibility of rotation, comprising fixed internal barrel of substantially cylindrical shape, outer shell (29), enclosing the shaft and installed with possibility of rotation around the imaginary vertical axis, wherein said shell (29) is rigidly connected to the U-shaped support base (20) so that its rotation also causes the centrifugal fan to rotate about said vertical axis, causing rotations of the sprayed jet to the left or right, wherein fixed inner barrel is simultaneously central oil distributor (31), supplying oil at least to hydraulic motor (2) of impeller, and has at least two holes (40) in the lower part for connection to the oil pipes coming out of the oil supply pump, wherein these holes serve as inlet openings into the channels passing inside the cylindrical shaft, each of which comes into a separate annular groove (41), wherein these grooves are located along the cylinder periphery, each groove at a different axial height along the cylinder, thus, inner wall of rotating shell (29) in combination with grooves (41) of cylindrical distributor and with seals (42) provided on side walls of grooves (41), form separate sealed annular oil chambers, two of which form part of hydraulic circuit (52) of engine (2), one relates to supply line, and other - to return line, wherein outer shell (29) comprises radial through hole (32) opposite each groove (41), said through holes have means of connection with oil hoses (24), extending at least to hydraulic motor (2) impeller.

EFFECT: disclosed is a device with a large operating radius, which ejects a sprayed jet, the action of which is based on creation of a powerful air flow with scattered therein liquid drops.
