Abstract

A wet particle storage tank includes a tank body capable of storing wet particles containing particles and solvent. The tank body has an upper storage section having a supply port through which the wet particles are supplied, a lower storage section located below the upper storage section and having a discharge port through which the wet particles are discharged, and a bridge forming section provided between the upper storage section and the lower storage section. The bridge forming section facilitates formation of a bridge by the wet particles to block falling of the wet particles from the upper storage section to the lower storage section.

First claim

What is claimed is:

1. A wet particle storage tank comprising a tank body configured to store wet particles containing particles and a solvent, wherein the tank body includes:
an upper storage section having a supply port through which the wet particles are supplied;
a lower storage section located below the upper storage section and having a discharge port through which the wet particles are discharged; and
a bridge forming section provided between the upper storage section and the lower storage section, the bridge forming section being configured to facilitate formation of a bridge by the wet particles to block falling of the wet particles from the upper storage section to the lower storage section, wherein:
the upper storage section and the lower storage section are formed in a cylindrical shape having a central axis that extends in a direction connecting the upper storage section and the lower storage section,
the bridge forming section has a neck portion formed at an axial central region of the bridge forming section, and
a cross-sectional area of the neck portion in a first plane perpendicular to the central axis is smaller than a cross-sectional area of a lower end portion of the upper storage section in a second plane perpendicular to the central axis, and is smaller than a cross-sectional area of an upper end portion of the lower storage section in a third plane perpendicular to the central axis.

2. The wet particle storage tank according to claim 1 , wherein the neck portion is curved to be convex toward the central axis.

3. The wet particle storage tank according to claim 1 , wherein:
the bridge forming section connects the upper storage section and the lower section, and
a surface roughness of an inner surface of the bridge forming section is smaller than the surface roughness of an inner surface of the upper storage section.

4. The wet particle storage tank according to claim 1 , wherein the bridge forming section connects the upper storage section and the lower storage section, and includes a solvent supply unit configured to supply the solvent toward an inner surface of the bridge forming section.

5. The wet particle storage tank according to claim 1 , further comprising a crushing member configured to break down the bridge formed in the tank body.

6. The wet particle storage tank according to claim 5 , wherein:
the crushing member includes an agitator configured to agitate the wet particles in the tank body, and
the agitator has an upper agitator configured to agitate the wet particles in the upper storage section, and a lower agitator configured to agitate the wet particles in the lower storage section.
