Abstract

PURPOSE: To prevent sludge from solidifying on the bottom surface, by giving oil a turning motion and thereby causing sludge to pile up in the center.
CONSTITUTION: A plurality of lateral stirrers 6, 7 and 8 are provided as mechanism to produce a circular flow. Each stirring shaft is tilted by θ with respect to the radial direction. By this, a circular flow is produced, and sludge is caused to pile up in the center of the tank bottom. By removing this sludge, it is possible to prevent sludge from solidifying on the bottom surface.
