Abstract

Liq. purifn. tank primarily for use as a recycling cleaner for coolants for machine tool operations. The liq. to be purified is introduced at the bottom of the tank to rise through a heavier liq. with which it does not mix; the lighter liq. settles on the top of the heavier, filtering liq. to await re-use. This is an uncomplicated, highly efficient filtration device and its efficiency does not fall to any extent as filtering continues. The filtering process is continuous, filtered liq. being drawn off from just below the surface.
