Abstract

A waste treatment apparatus includes: a body having a spherical shape and configured to accommodate a waste therein; and a stirring unit configured to stir the waste accommodated in the body. The stirring unit includes: a main shaft horizontally and rotatably disposed at a center portion in the inside of the body; a plurality of main shaft stirring blades having a flat plate shape, the plurality of main shaft stirring blades mounted on a surface of the main shaft; a plurality of support rods assembled to the main shaft at a predetermined interval, the plurality of support rods extending perpendicularly toward an inner peripheral surface of the body; and a plurality of stirring blades each having a rectangular flat plate shape, the plurality of stirring blades being mounted on distal ends of the plurality of support rods on an inner peripheral surface side of the body.

Dependent claims

A waste treatment apparatus comprising:

a body having a spherical shape and configured to accommodate a waste therein;
and
a stirring unit configured to stir the waste accommodated in the body, wherein
the stirring unit includes:
a main shaft horizontally and rotatably disposed at a center portion in an inside of the body;
a plurality of main shaft stirring blades having a flat plate shape, the plurality of main shaft stirring blades being mounted on a surface of the main shaft;
a plurality of support rods assembled to the main shaft at a predetermined interval, the plurality of support rods extending toward an inner peripheral surface of the body;
and
a plurality of stirring blades each having a rectangular flat plate shape, the plurality of stirring blades being mounted on distal ends of the plurality of support rods on an inner peripheral surface side of the body, wherein
the stirring unit further includes a detachably mounting portion that is configured to detachably mount the stirring blade on the support rod at a desired angle with respect to a center axis of the support rod,
the main shaft stirring blade is formed in a triangular shape where one end of the main shaft stirring blade in a longitudinal direction of the main shaft is set relatively higher than the other end of the main shaft stirring blade in the longitudinal direction of the main shaft as viewed in a side view, and
the main shaft stirring blade is formed on a surface of the main shaft in a state where the main shaft stirring blade is bent in the longitudinal direction as well as in a circumferential direction.
