Problems solved by technology

As a result, especially in the case of stirring a small-capacity material to be stirred, the area of ​​the blade portion 102a immersed in the material to be stirred is small, resulting in a portion (dead space) where the material to be stirred is stagnant, and sufficient agitation cannot be performed.
[0018] In addition, in the prior art, since stirring is performed under high shear (high power), fine aggregates are generated during emulsion polymerization, and there is a problem that fine particles are generated during suspension polymerization.

Example Embodiment

[0042] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0043] figure 1 This is a schematic diagram showing a stirring device according to an embodiment of the present invention. The stirring device includes a stirring tank 1 having a vertical cylindrical shape, a stirring blade 2 rotatably installed in the stirring tank 1, a baffle portion 3 fixedly arranged at a predetermined position in the stirring tank 1, and the like. The stirring blade 2 is composed of a blade portion 21 and a stirring shaft 22. The blade portion 21 is composed of two blade configuration portions 21a. The stirring shaft 22 is connected to a driving portion 4 provided at an upper portion outside the stirring tank 1 and driven to rotate.

[0044] The stirring tank 1 has a vertical cylindrical shape as described above, and a stirring blade installation port 5 used to install the stirring blade 2 inside the stirring tank 1 is provided on the top 1a, and used w
