ABSTRACT:
A reconditioning system which withdraws coolant from a machine tool sump, filters solids from the coolant, removes tramp oil from the coolant, kills bacteria in the coolant, and returns the reconditioned coolant to the machine tool sump. The reconditioning system includes a separator tank having a coolant inlet, a coolant outlet, and a coalescer pack located between the coolant inlet and the coolant outlet to separate tramp oil from the coolant. An ozone generator is connected to the separator tank for dissolving ozone into the coolant to kill bacteria, yeast and fungus. An in-sump pickup includes a flexible intake hose connected to the separator tank coolant inlet, a suction nozzle having a generally rigid tube attached near an angled or fluted inlet end of the intake hose, and a ring-shaped float encircling the rigid tube. A discharge hose connects the separator tank coolant outlet and the sump. A split diaphragm air pump withdraws coolant from the sump through the intake hose and forces coolant to the sump through the discharge hose. A skimmer assembly removes tramp oil from the surface of the coolant in the separator tank. The skimmer assembly includes a skimmer roll which rotates about a horizontal axis, a storage tank, a reversing electric motor which alternately rotates the skimmer roll in each direction, and a wiper blade which scrapes tramp oil off the peripheral surface of the skimmer roll and directs the tramp oil into the storage tank.
