Abstract

An object is to provide a slurry storage and stirring device which can sufficiently flow even a high-concentration slurry by a simple means and is excellent in stirring properties. Disclosed is a slurry storage and stirring device including a container which stores a slurry containing particles and a solvent, and in this device, the container has an inner wall provided inside the container and formed of a porous body which passes a gas supplied to the container through the porous body to generate fine bubbles in the slurry.

First claim

1 . A slurry storage and stirring device comprising a container which stores a slurry containing particles and a solvent,
wherein the container has an inner wall provided inside the container and formed of a porous body which passes a gas supplied to the container through the porous body to generate fine bubbles in the slurry.

2 . The slurry storage and stirring device according to claim 1 , wherein the container has a cone portion whose cross-sectional area decreases toward a bottom of the container.

3 . The slurry storage and stirring device according to claim 1 , wherein the inner wall has an inclined portion inclined with respect to a vertical direction.

4 . The slurry storage and stirring device according to claim 1 , wherein at least a portion on the bottom side of the container has a double structure of an inner body having the inner wall in at least a part of the inner body and an outer body provided outside the inner body.

5 . The slurry storage and stirring device according to claim 4 , wherein the inner body and the outer body are provided to be spaced apart from each other, and
a supply port configured to supply the gas to a space between the inner body and the outer body is provided at a bottom of the outer body.

6 . The slurry storage and stirring device according to claim 4 , wherein the inner body and the outer body are configured to be separable from a main body portion on a side opposite to the bottom side of the container.

7 . The slurry storage and stirring device according to claim 1 , further comprising a defoaming device in the container.
