Abstract

A size of an agitating mechanism can be reduced. An agitating mechanism according to an aspect of the present disclosure is an agitating mechanism for agitating fluid flowing through inside a pipe, including: a rotary body placed inside the pipe so as to be able to rotate in a circumferential direction of an inner circumferential surface of the pipe; and a regulation part configured to regulate a movement of the rotary body in a longitudinal direction of the pipe. The rotary body includes a hollow part penetrating the pipe in the longitudinal direction of the pipe and an agitating blade provided in the hollow part.

First claim

What is claimed is:

1. An agitating mechanism for agitating fluid flowing through a pipe, comprising:
a pipe; and
a rotary body placed inside the pipe so as to be able to rotate in a circumferential direction of an inner circumferential surface of the pipe; wherein
one of the pipe and the rotary body is configured to regulate a movement of the rotary body in a longitudinal direction of the pipe, wherein
the rotary body comprises a hollow part penetrating the pipe in the longitudinal direction of the pipe and an agitating blade provided in the hollow part, a planetary gear wheel configured to be engaged with an internal tooth part continuously formed in the circumferential direction of the inner circumferential surface of the pipe, and a sun gear wheel configured to be engaged with the planetary gear wheel, wherein the sun gear wheel comprises the hollow part penetrating therethrough in a thickness direction and the agitating blade provided in the hollow part.

2. The agitating mechanism according to claim 1 , wherein the rotary body comprises a cylindrical body and the agitating blade disposed in a hollow part of the cylindrical body, and
an outer edge of the cylindrical body is inserted, as a regulation part, into a recess continuously formed in the circumferential direction of the inner circumferential surface of the pipe.

3. The agitating mechanism according to claim 1 , wherein a tooth of each of the internal tooth part, the planetary gear wheel, and the sun gear wheel is a helical tooth, and
an engaging part between the internal tooth part and the planetary gear wheel, and an engaging part between the planetary gear wheel and the sun gear wheel serve as a regulation part.

4. The agitating mechanism according to claim 1 , wherein a recess is continuously formed in the circumferential direction of the inner circumferential surface of the pipe,
the internal tooth part is formed on the bottom of the recess,
the planetary gear wheel is placed inside the recess, and in a place where the planetary gear wheel is engaged with the sun gear wheel, a tip of the sun gear wheel is placed closer to an outer circumferential surface of the pipe than an inner circumferential surface of a region of the pipe adjacent to a region of the pipe where the recess is formed is, and
a side surface of the recess serves as a regulation part.

5. The agitating mechanism according to claim 1 , wherein the planetary gear wheel includes the hollow part penetrating therethrough in the thickness direction and the agitating blade provided in the hollow part.
