Can be measured.

FIGS. 5 and 6 show a second embodiment of the oblique shaft stirrer according to the present invention, particularly showing a modification of the stirring means 7A provided on the annular stirrer 5A. The plate blade-like one, the other, and the upper stirring members 7Aa, 7Bb, 7Dd, which are the stirring means 7A, are arranged in multiple stages parallel to the left and lower, respectively, and one and the other stirring members 7Aa, 7A.
Between Bb, a connecting member 7Cc is positioned on an axis connecting the upper oblique axis 4A and the lower oblique axis 6A, and both stirring members 7A
a, 7Bb are fixed at the opposite end faces. The stirring means 7A includes one stirring member 7Aa inclined upward at a predetermined angle, which is connected substantially on the axis connecting the upper inclined shaft 4A and the lower inclined shaft 6A, and the other stirring member inclined downward at a predetermined angle. A disc-shaped connecting member 7Cc having a large cross-sectional area at the connecting portion is interposed between the one and the other stirring members 7Aa and 7Bb.

The one and other stirring members 7A
a, 7Bb are fixed to the stirrer 5A at their outer ends,
The opposite ends of the stirring members 7Aa and 7Bb are fixed to the connecting member 7Cc, respectively.
b may be such that the inclination angle can be adjusted in the same manner as in the first embodiment.

The other stirring member 7b tilted downward
A space is provided above b, but an upper stirring member 7Dd is provided substantially similarly to one of the stirring members 7Aa inclined upward, and an outer end of the upper stirring member 7Dd is a stirrer. 5 and the inner end is fixed to the auxiliary shaft 8A.

The auxiliary shaft 8A is fixed to the upper part of the stirrer 5A and the uppermost connecting member 7Cc. Further, by fixing the temperature sensor mounting member 9A to the center of the upper oblique shaft 4A and bending it from the middle, most of the temperature sensor mounting member 9A is not located on the axis connecting the upper oblique shaft 4A and the lower oblique shaft 6A. In this way, a temperature sensor 10A is continuously provided at the lower end of the mounting member 9A, and the temperature sensor 10A is arranged close to the lower end of the stirrer 5A.

The shapes of the stirring members 7Aa and 7Bb are as follows.
