Document Type and Number:

WIPO Patent Application WO/2023/223814

Kind Code:

A1

Abstract:

The present invention comprises: a first filtration unit 102 provided to the bottom-section side of an enclosing container 3, the first filtration unit 102 being obtained by laminating wet cakes 202 that are subject fluids; a fluid medium introduction unit 104 for introducing, from the bottom-section side of the first filtration unit, a fluid liquid 103a that is a fluid medium in which the wet cakes 202 are allowed to flow; and a stirring part having a stirring shaft 4a that is rotatably disposed inside the enclosing container, and a stirring blade 5 that is provided to the stirring shaft 4a and that stirs the wet cakes at the upper-surface side of the first filtration unit 102. A fluid medium discharge hole 4b through which the fluid liquid 103a can be discharged is formed in the stirring shaft 4a, which stirs the stirring blade 5. An upper-section region of the enclosing container 3 is provided with a second filtration unit 111A that captures microparticles of the wet cakes. The second filtration unit 111A is installed on the stirring shaft 4a and has a flow path 111a through which the fluid liquid can pass. The flow path 111a communicates with the fluid medium discharge hole 4b within the stirring shaft 4a.
