Abstract
A coolant recycling apparatus having first and second storage tanks mounted on a wheeled cart. The first tank has a suction device associated therewith to which is coupled a flexible suction hose to suck contaminated coolant from the sump of a machine tool, whereby the coolant flows through the suction device and then through a filter for removing larger solids, whereupon the contaminated coolant is then deposited in the first tank. A pump sucks the contaminated coolant from the first tank and supplies it to a filter disposed adjacent the upper end of the second tank. This filter has a stack of oil absorbent pads which remove tramp oil as the coolant flows downwardly and then collects in the second tank. The clean coolant in the second tank is sent back to the pump through suitable valving which enables the coolant to be supplied to a dishcarge hose which feeds the clean coolant back to the sump.
