A cover plate 4 is placed over the flange at the upper mouth of the tank 1, and a cylindrical cover 5 with an end plate is placed over the cover plate 4.
It is also fastened to the flange with bolts. Further, the dish-shaped seat plate 6 is fastened to the cover plate 4 with bolts, with the seal 7 housed inside the plate-shaped seat plate 6.
Thereby, the seal 7 is pressed against the cover plate 4, and the portion where the core rod 10 passes through the cover plate 4 is reliably sealed. A thrust bearing 8 is mounted on the upper surface of the seat plate 6. On the center line of the tank 1, the core rod 10 is inserted through the cover plate 4, and its upper end is rotatably suspended by a bearing 8, and its lower end faces the bottom of the tank 1. A hollow shaft 11 is fitted into almost the entire portion of the core rod 10 below the cover plate 4 so as to be rotatable independently of the rotation of the core rod 10. Hollow shaft 1
A cup-shaped gasket 12 with a core rod 10 inserted therein is interposed between the upper end of the lid plate 4 and the lower surface of the lid plate 4. Also sealed. Therefore, the seal 7 and the packing 1
2, it is possible to almost completely prevent foreign matter from entering the tank 1 from outside.

When the magnets 6 and 17 rotate, the external magnets 18 and 19 inserted therein also rotate. Also, the drawing shows magnets 18,
19 is shown in the same position, but rings 16 and 17
If the external magnets 18 and 19 are slightly rotated to shift the positions of the external magnets 18 and 19, the horizontal bars 13 and 14 are displaced, and the mounting angle, that is, the pitch, of the flexible vane 15 changes accordingly. By this operation, the stirring efficiency of the content liquid A can be changed arbitrarily. When the rings 16 and 17 are rotated in the same direction and speed by the rotating means,
The horizontal bar 1 is attached to the rotating external magnets 18 and 19.
3 and 14 rotate, and the content liquid A is stirred by the vane plate 15. Of course, if the rotational speed of the rings 16 and 17 is changed, the rotational speed of the blade 15 will also be changed.
