Abstract
Abstract An oil reclamation device comprises a housing, filter, evaporator plate and heating assembly. The housing has a longitudinal axis and includes an oil inlet to receive oil to be reclaimed and an oil outlet to discharge reconditioned oil. The filter is disposed at one end of the housing to define a mechanical filtration zone which receives the oil from the oil inlet of the device. The evaporator plate is disposed within the housing adjacent the mechanical filtration zone. The heating assembly is disposed at the open end of the housing adjacent the evaporator plate to define an evaporation chamber therebetween. The evaporator plate includes upwardly projecting evaporation walls defining a plurality of curved vaporizing surfaces laterally displaced radially with respect to each other to form a fluid traveling surface therebetween. The heating assembly includes downwardly projecting heating walls defining a plurality of curved heating surfaces located between the curved vaporizing surfaces. The evaporation walls and the heating walls define a plurality of curved paths along the fluid traveling surface from the longitudinal axis of the housing outwardly along the evaporator plate. Evaporator plate includes passageways extending from the mechanical filtration zone to deliver substantially all of the oil being treated at a centermost portion of the evaporator plate. The evaporation walls and the heating walls provide a structural configuration effective to guide the oil from the centermost portion of the plate outwardly along the curved paths to the oil outlet of the housing.
