Abstract

PURPOSE:To enable the revolutionary motion of an impeller with agitation resistance and to simplify the structure of an agitator by fitting a transverse supporting arm which receives torque caused around a driving shaft by means of agitation resistance exerted to the rotating impeller so that the transverse supporting arm can not be moved to the axial direction of the driving shaft and fitting an agitating shaft fitted with the impeller to this arm so that it can not be moved to the axial direction. CONSTITUTION:The rotation of a driving shaft 2 is transferred to the agitating shafts 4, 5 via the gears 6, 7, 8 and the agitating shafts 9 are subjected to rotational motion and a mixture to be agitated which is introduced into an agitation tank 1 is agitated with the impeller 10 fitted to the lower end thereof. In this case, since agitation resistance due to the mixture to be agitated acts on the impellers 10, torque caused around the driving shaft 2 is generated in a supporting arm 3 by means of this agitation resistance. As a result, the agitation shafts 9 are subjected to revolutionary motion around the driving shaft 2. The mixture to be agitated is uniformly agitated in a range over all regions of the agitation tank 1 with the impellers 10 of the agitating shafts 9 which are subjected to revolutionary motion while performing rotational motion in such a way.

ものである。(Means for Solving the Problems) In order to achieve the above object, the stirring device of the present invention has a horizontal support arm near the lower end of the vertical drive shaft, which is immovable in the axial direction of the drive shaft. A vertical stirring shaft with a stirring blade attached to the lower end is pivotally mounted on the end of the support arm so as not to be movable in the axial direction, and a rotation transmission member is connected between the stirring shaft and the drive shaft. It is characterized by being connected by.

直となっているが、傾斜させてもよい。Gears 7.8 are fixed to the upper end of the stirring shaft 4.5, and these gears 7.8 mesh with the gear 6 fixed to the drive shaft 2, so that the rotation of the drive shaft 2 is transmitted to the stirring shaft 4.5. It has become so. A stirring blade 9 having a plurality of blade plates 10 is fixed to the lower end of the stirring shaft 4°5. Although the blades 10 are vertical in the illustrated example, they may be inclined.
