Disclosed is a multi-shaft agitator for preventing oil leakage. Lubrication oil charged in the multi-shaft agitator for preventing oil leakage is prevented from being leaked, so the multi-shaft agitator for preventing oil leakage may be safely installed and used in a water purification plant. The multi-shaft agitator for preventing oil leakage may rotate two output shafts at different RPMs and in different directions by using a rotational force generated from one single driving means, and may prevent gas generated in an agitation tank from being discharged to the outside of the agitation tank. The multi-shaft agitator for preventing oil leakage comprises: a first deceleration means for receiving a rotational force transferred from a driving means coupled with a housing, and thus outputting a rotational force decelerated at a particular ratio to be rotated in an opposite direction to a rotational shaft of the driving means; a second deceleration means for receiving the rotational force from the first deceleration means, and thus outputting a rotational force decelerated at a particular ratio to be rotated in an opposite direction to an output shaft of the first deceleration means; a first shaft rotated by receiving the rotational force decelerated at a particular ratio by the second deceleration means; a third deceleration means for receiving the rotational force transferred from the first shaft, and thus outputting a rotational force decelerated at a particular ratio to be rotated in an opposite direction to the first shaft; a second shaft rotated by receiving the rotational force decelerated at a particular ratio by the third deceleration means; and a first oil leakage prevention means for preventing lubrication oil charged in the driving means or the housing from being leaked through a space between the housing and the first shaft even when the first and second shafts are eccentrically rotated. |
