DEVICE FOR IMPREGNATION OF WOOD UNDER PRESSURE FROM WOOD END Russian patent published in 2014 - IPC B27K3/02 

FIELD: process engineering.

SUBSTANCE: invention relates to woodwork, particularly, to equipment for through impregnation of wood with fluids. Proposed device comprises welded frame 1 with metal tube 2 secured thereto, left taper nozzle 3, right taper nozzle 4, ultrasound radiator 5 acting radial direction, impregnation fluid tank 6, hydraulic pump 7, pressure gage 8, pressure pneumohydraulic accumulator 9, hydraulic pulsator 10 with check valve, auxiliary pipeline 11, water collection tank 12, horizontal hydraulic cylinder 13, ultrasound radiators 14 acting in horizontal direction. Extra ultrasound radiators are secured in metal tube generatrix to get in contact with processed wood at spacing multiple of half the ultrasound wavelength in wood. Hydraulic pulsator incorporates encased distribution mechanism composed of the shaft with mutually perpendicular bores and working fluid feed channels that allow working fluid oscillation frequency of 0.3-10 Hz and amplitude of 0.1-0.2 mm.

EFFECT: expanded performances.
