SOLID-LIQUID AGITATOR

PURPOSE:To provide the solid-liquid agitator which uniformly agitates and mixes the liquid phase or solid and liquid phases in a container and can efficiently agitate and mix the solid phase. CONSTITUTION:This agitator is constituted by disposing a motor 5 for revolution and a motor 7 for rotation with a speed changer 8 on the outside of the inverted circular conical container 1 and pivotally supporting a revolving shaft 2 which is disposed in proximity to the inner peripheral wall surface of the container 1 and has spiral vanes 3 to the front end of a hollow revolving shaft 4b extending radially from the upper part in the central part of the container at its front end in such a manner that this device can be revolved and rotated by the motors. A part of the upper part of the spiral vanes 3 is substd. with a plane vane 9. This plane vane 9 exists upper than the solid phase boundary S.
