Patent ID: 7093718

Claim:
An inline sifter, comprising: a gas-powder mixture receiving module, provided with a supply chamber, which receives a mixture of a gas and a pneumatically transported powdery material from a gas-powder mixture inlet; a sieving module, provided with a sieving chamber, which laterally communicates with said supply chamber of said gas-powder mixture receiving module; a rotating mechanism, provided with a rotating shaft, which is laterally extended inside said supply chamber and said sieving chamber; a cylindrical sieve arranged such that said rotating shaft extended in said sieving chamber passes through a center thereof; a wind power amplifier located in an internal area of said sieve and having multiple blades fixed to said rotating shaft to amplify wind power and pressing said powdery material out from said internal area of said sieve toward an external area; a removal member used to remove a remaining powdery material and/or foreign substances, which has not passed through said sieve, from said internal area of said sieve; and an outlet which discharges a sieved powdery material that has passed through said sieve from said internal area toward said external area, wherein said gas-powder mixture, which is supplied by said gas-powder mixture inlet in a circumferential direction from a circumferential face of said supply chamber, flows around said rotating shaft, and is fed into said sieving chamber, wherein said supply chamber has a cylindrical shape, and said gas-powder mixture inlet is connected to said supply chamber in said circumferential direction of said circumferential face of said supply chamber along a line tangential to said circumferential face of said supply chamber, and wherein said multiple blades laterally extend inside said supply chamber and said receiving chamber to stir the gas-powder mixture supplied by the gas-powder mixture inlet.
