のである。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, reference numeral 1 is a stirring blade for mixing and stirring liquids, which is arranged in a stirring tank 2 having a bowl-shaped bottom and is connected to an electric motor 3 to rotate.

メタルなどが使用される。The stirring blade 1 is shaped so as to stir the liquid A filled in the stirring tank 2 over almost the entire area. That is, the stirring blade 1 includes a support shaft body 11 connected to the electric motor 3 side, and a pair of left and right flat plate-shaped blade plates 1 attached so as to project on both sides of the support shaft body 11.
2 and each of these vanes 12 has a large number of holes 13 having a predetermined diameter (for example, about 1/100 to 1/10 of the inner diameter of the stirring tank 2) formed at predetermined intervals. Is. For example, punching metal or the like is used as a constituent material of each blade 12.

A skirt portion 12a having, for example, an arc shape is formed so as to follow the shape of the inner bottom surface 2a, and a cutout portion 12b is provided in a portion near the support shaft body 11. The skirt portion 12a has no hole 13 formed therein.

の数は多い方がよい。Therefore, when the liquid is mixed by the above-mentioned stirring blade 1, as shown in FIG. 2, when the liquid passes through a large number of holes 13 formed in each blade 12, its inner peripheral surface Since the liquid is separated into the spiral V, the dispersibility of the mixed liquid becomes good. That is, since the blade 12 moves in the direction perpendicular to the liquid (see FIG. 2), the vortex generated when passing through the hole 13 promotes microscopic mixing, and the blade 12 is almost Since the liquid has a shape corresponding to almost the entire area of the stirring tank 2, efficient mixing and stirring is performed over the entire stirring tank 2. In the case of the ribbon screw, the blade crosses the liquid obliquely, which is inferior in that the liquid is dispersed as compared with the case of moving in a direction perpendicular to the liquid. Also, the anchor wing is
Although the stirring blade 1 is the same as the stirring blade 1 in that it moves in a direction perpendicular to the liquid, the length of contact with the liquid in the stirring blade 1 of the present embodiment (inner circumferential distance of hole portion × number of holes) is Since the contact length with the liquid in the anchor blade, that is, the outer peripheral distance is longer, the dispersibility is improved. Therefore, the hole 13
The better the number of.
