DRIER FOR SOLUTIONS IN BOILING BED OF PULSE-TYPE INERT OBJECTS Russian patent published in 2008 - IPC F26B3/12 

FIELD: heating.

SUBSTANCE: invention refers to drying engineering applied to dispersed materials in boiling bed and can be implemented in aniline-colour, food, pharmaceutical, microbiological, chemical and other industries. Drier for solutions in boiling bed of inert objects contains drying cabinet with injectors, two gas grids one of which contains main conical distributor. Head nozzle from inert bodies is mounted between gas grids. Another gas grid additionally contains conical distributor and actuating vertical shaft movable vertically and rotationally and driven by worm gear set. Apexes of main conical distributors of gas grids are turned towards one another. Injector is acoustic and contains case with in-built ultrasonic oscillator designed as nozzle and ring resonant cavity. Case is designed as vertical linear bushing in upper part of which there is air nozzle mounted with its axis perpendicular to solution nozzle. And case contains in-built coaxial with upper and lower flange plates with lower flange plate rigidly fixed in in-case groove. Bushing contains coaxial ring resonant cavity executed in the form of cup with conic surface. Cup is inserted in resonant cavity rod of diameter d. And its tail part includes locking disks designed as elastic petals connected to internal surface of bushing. Lower flange plate contains one nozzle at the angle 20°÷40° to axis of resonator cavity. Axis of nozzle extends on circle in midsection of conic surface. Internal surface of bushing contains formed coaxial tapered and parallel holes.

EFFECT: higher drying output.
