Patent ID: 8348605

Claim:
A device for discharging a fluid comprising: a main chamber adapted to receive a fluid and containing solid particles fluidized by the fluid through a rotary chamber, wherein the rotary chamber is bounded by a rotary circular wall, surrounding and rotating about a rotation axis disposed within the main chamber and connected to a rotation device for rotating the rotary circular wall and comprising: at least one inlet opening disposed through at least one wall, enabling the fluid to enter the rotary chamber; blades disposed along the rotary circular wall for rotating the fluid and the solid particles entrained by the fluid into the rotary chamber; at least one central outlet opening around the rotation axis adapted to discharge the fluid from the rotary chamber; at least one fixed central discharge tube, the discharge opening of which communicates with the central outlet opening of the rotary chamber; at least one fixed wheel fixed around and on the outside of the rotary circular wall; and at least one delivery opening along the rotary circular wall enabling the fluid and the solid particles running along said rotary circular wall inside said rotary chamber to enter the space located between said fins and to be delivered into said main chamber by centrifugal force when the device is operating.
