Abstract
An oil reclamation device includes an evaporator head and base both of heat conductive material and defining an evaporator chamber between them. An upwardly vertically extending heating element is disposed within the evaporator base for heating oil containing contaminants within the evaporator chamber by conduction and convection to evaporate light contaminants/liquids (e.g. water, fuel or antifreeze) in the oil. A vent extends from the evaporator chamber through the head, and an oil discharge conduit provides gravity discharge from the evaporator chamber and is formed in the base. An oil inlet conduit feeds oil from the head toward the evaporator chamber, preferably through a plurality of substantially evenly spaced passages formed in the head and flaring outwardly from the oil inlet conduit to the evaporator chamber to provide flow of oil in small, distinct, spaced streams to impact a portion of a generally annular frustoconical wall element extending upwardly form the base toward the head. An oil filter having a density differential between an outer canister and an inner central mandrel is mounted on the head for removing particles from the oil before it is refined.
