Claims

[Scope of Claim for Utility Model Registration] 1. A rotary shaft is disposed along the central axis of a hopper whose lower end discharge port is connected to a powder transfer device such as a single-shaft eccentric screw pump or a screw feeder, A center screw is disposed so as to be integrally rotatable on the rotation shaft, and a ribbon screw in a direction opposite to the spiral direction of the center screw is brought close to the inner wall of the hopper on the outside of the center screw in the radial direction, and the rotation is performed. A powder fluidization device for powder transfer, characterized in that it is rotatably arranged on a shaft. 2. Powder fluidization according to claim 1, wherein the spiral direction of each screw is set so that the ribbon screw pushes down the powder and the center screw pushes up the powder by rotation of the rotating shaft in a specific direction. Device. 3. Powder fluidization according to claim 1, wherein the spiral direction of each screw is set so that the ribbon screw pushes up the powder and the center screw pushes the powder down by rotation of the rotating shaft in a specific direction. Device. 4 Near the discharge port at the lower end of the hopper of the rotating shaft,
The powder fluidization device according to any one of claims 1 to 3, further comprising a screw member or an inclined fin that pushes down the powder by rotation of the rotating shaft in a specific direction. 5 Connect the suction port of a single-shaft eccentric screw pump to the discharge port at the lower end of the hopper, connect the rotor of the pump to the lower end of the rotating shaft, and drive the rotor together with the rotating shaft by a drive device disposed above the rotating shaft. The powder transfer device according to any one of claims 1 to 4, which is configured to rotate.
