DRYING UNIT WITH INERT HEAD Russian patent published in 2008 - IPC F26B3/12 

FIELD: heating.

SUBSTANCE: drying unit with inert head contains drying cabinet with injection nozzle, cyclone cell, heat-generator, vent unit, air duct and rotary gate. Heat-generator for air cleaning and heating contains frame with partitioned thermal-radiation gas burners mounted astride. Upper part of heat-generator contains intake socket with built-in pump baskets. Intake air delivered to heat-generator runs through cyclone cell along gas burners. It is heated up and delivered to drying cabinet. Vent unit consists of two series high-pressure fans. Self-loading rotary gate consists of the body with in-built rotor rotatable by motor reducer. Drying cabinet is cone shaped with upper part slipping to cylinder. Cabinet contains axially centrally located dome. Intake air clearing is provided by bottom between body and dome. Solution injection nozzle is acoustic and consists of 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 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.
