ABSTRACT:
A tractor trailer chassis compactly mounts a waste oil cleaning apparatus of hydraulically connected, primary components. A diesel fuel burner fired heater of vertical cylindrical form mounts at one end of the chassis. A blower feeds a large volume of air under pressure to a cylindrical fire box where a fuel air mixture is ignited and fed tangentially into the base of the central chamber within the heater where the products of combustion follow a helical path within the central heat exchange chamber. Waste oil is fed counterflow along a second helical path through an annular chamber separated by a cylindrical metal heat conductive wall from the chamber bearing the products of combustion. Heated waste oil is fed from the heater to a vibrating table type solids separator or shaker mounted at the opposite end of the trailer chassis from the heater where solids are separated from the heated waste oil. An elongated oil/water separator tank extends the major length of the trailer chassis and is positioned between the heater and the solids separator. The waste oil with solids removed is discharged under gravity flow into the first upstream compartment of the oil/water separator. Vertical transverse walls within the separator tank define weirs of decreasing height to insure water separation from the oil prior to oil flow to the last compartment remote from the solids separator. Water collecting within the separator tank compartments is fed through parallel feed pipes to a common manifold.
