Description of the Related Art In the fields of polymer production, polymer chemical reaction apparatus, etc., in which a plurality of types of liquids or a mixed medium of liquids and solids are stirred and mixed, a stirrer having a shape and a principle according to its purpose is widely used. . In general, liquids, liquids, or liquids
The stirring and mixing of solids is performed by driving a mixing blade rotating in a stirring tank to give a predetermined power to the mixing medium,
This is done by the dissipation of energy due to the viscosity of the mixed fluid.
That is, a circulating flow and a shear flow are generated in the mixed medium by the driving of the mixing blades in the radial direction and the axial direction, and mixing is performed depending on these flow states to generate an energy loss. Therefore, in order to perform efficient stirring and mixing,
The rate of homogenization of the mixed medium with respect to the power applied per unit volume of the mixed medium is a problem.

・混合されている。Conventionally, there are many types of mixing blades such as edge turbine blades, propeller blades, turbine blades, anchor blades, ribbon blades, etc. These mixing blades have a specific gravity, viscosity and chemical reaction state of the mixed liquid. Selected by the body. Furthermore, even when the same mixed liquid is mixed using a certain type of mixing blade, an outer diameter that is inversely proportional to the viscosity is used, or the same type of mixing blade is used in a plurality of stages with a certain interval on one drive shaft. It is attached. Further, different types of mixing blades are separately placed by the respective drive shafts and agitated and mixed depending on the purpose.

好ましくないという問題があった。However, depending on the type of the mixing blade or the type of the mixing medium, the mixing medium may adhere to the mixing blade or the like to prevent efficient stirring and mixing. For example, a ribbon blade is usually supported by a single helical blade or a double, triple blade, or other helical blade on the shaft, but the mixed medium adheres to the shaft and the support, resulting in reduced efficiency, which is not preferable in practice. There was a problem.

なされなかった。Further, in order to increase the shearing force, a short fence-shaped baffle (baffle plate) is attached to the inner wall surface of the stirring tank at a slight distance from the mixing blade and in parallel with the axis. There is a problem in that the mixed liquid adheres to and the shearing force is reduced and the stirring efficiency is reduced. Further, particularly in the case of stirring and mixing the powder and the liquid, the stirring efficiency is poor and a large amount of power is required, and even if the stirring is not performed for a long time, uniform mixing cannot be achieved.

きる。As is apparent from the above description, according to the present invention, the spiral flat blades, the propeller blades, and the mixing blades mounted on the outer peripheral wall of the support ensure that the circulating flow in the stirring tank is entirely within the stirring tank. The mixing is carried out effectively and there is a turbulent flow due to the shear flow, so that the mixing is effectively performed, so that the stirring efficiency can be improved and the mixing is carried out in a short time. In addition, due to the entire flow, the mixed liquid does not adhere to the mixing blades and the supporting portion, and high efficiency can be maintained for a long time. Therefore, according to the stirrer of the present invention, stable stirring and mixing can be performed even if there is a rapid change in viscosity in the process of producing a solid from a liquid in the polymer manufacturing process of polymer chemistry. Furthermore, since it is highly efficient and is agitated coaxially, it is possible to provide a small agitator.
