DRYING UNIT FOR THERMOLABILE MATERIALS Russian patent published in 2008 - IPC F26B3/12 

FIELD: heating.

SUBSTANCE: drying unit for thermolabile materials, mainly calcium hypochlorite, contains chamber, sprayer of calcium hypochlorite growth solution, inert gaseous heat carrier pipeline, dried material discharge manifold connected to pipeline providing pneumatic transportation of dried material, additional heat carrier inlet manifold. Pipeline with its other end is connected to dust cleaning system. Sprayer 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 calcium hypochlorite nozzle. And case contains in-built coaxial rigid bushing 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.
