Rotary Fluidized Powder Bed for Fine Viscous Powder Flow

The patent introduces a rotating mechanism that transforms the static fluidized bed into a dynamic system. The rotating shaft with inclined plates creates continuous motion, generating centrifugal force and varying gas flow patterns that effectively process fine viscous powders which cannot be handled by traditional static fluidized beds.

The rotation of the shaft creates periodic action through the inclined plates, where gas flows through the powder layer in repeated cycles. This periodic gas flow pattern enhances mixing and prevents powder agglomeration, solving the problem of poor processing effect for fine powders with high viscosity.

The rotating inclined plates create mechanical disturbance and vibration effects on the powder bed. This mechanical action breaks up adhered powder clusters and maintains particle separation, preventing strong adhesion from compromising flowability during the fluidization process.

The patent uses gas flow through the fluidized bed to counteract adhesion forces. The gas streams created by the rotating mechanism lift and separate particles, using pneumatic forces to overcome the adhesive forces that cause powder clumping and improve flowability.
