Abstract

Oil and impurities collected by a cleaning fluid during cleaning of machine parts are removed by sepn. The liq. mixt. gathers in a collecting vessel in which oil tends to float on the surface with the cleaning liq. below. A float, designed to rest just beneath surface of oil layer, has an opening on its top and a central pipe which moves telescopically on the suction pipe of a pump, the liq. mixt. flowing down the pipe to the pump and being transferred to a sepn. chamber. Baffles in this chamber slow down the rise of the liq. mixt. to the top giving good sepn. of the oil, which floats on the surface and is drained off via an overflow. A dividing wall open at the bottom of the sepn. chamber forms a flow-off well and the purified cleaning fluid rises in this flowing over a weir and back into the collecting vessel. Process gives better sepn. of oil and increased recovery of cleaning fluid.
