Claims
- 1. An oil reclamation device comprising;
- an evaporator head;
- an evaporator base mounted to and below said evaporator head, said head and base defining an evaporator chamber therebetween;
- a heating element connected to said evaporator base for heating oil containing contaminants within said evaporator chamber by conduction and convection to evaporate light contaminants in the oil;
- a vent from said evaporator chamber;
- an oil discharge conduit from said evaporator chamber formed in said evaporator base; and
- an oil inlet conduit feeding oil from said head toward said evaporator chamber.
- 2. An oil reclamation device as recited in claim 1 further comprising an oil filter for filtering oil prior to the oil passing into said oil inlet conduit.
- 3. An oil reclamation device as recited in claim 2 wherein said oil filter is mounted to said evaporator head on the opposite side of said evaporator head from said evaporator base.
- 4. An oil reclamation device as recited in claim 3 wherein said oil filter comprises an outer canister having filtering media therein, and a central perforated mandrel; said filtering media having a density differential of at least about 10% between said outer canister and said central mandrel, the density being higher adjacent said mandrel than adjacent said canister; and wherein said oil inlet conduit is adjacent said central mandrel, said oil filter supported on said evaporator head.
- 5. An oil reclamation device as recited in claim 4 wherein said filtering media comprises continuous filament unbleached natural cotton wrapped around said perforated mandrel.
- 6. An oil reclamation device as recited in claim 1 wherein said evaporator base comprises a base element and at least one generally annular wall element extending upwardly from said base element toward said evaporator head, said annular wall member having at least one channel formed therein for allowing drainage of oil.
- 7. An oil reclamation device as recited in claim 6 wherein said heating element is substantially concentric with said wall elements, and comprises a sealed stainless steel electrical resistance heating element.
- 8. An oil reclamation device as recited in claim 6 wherein the oil containing contaminants is heated in said evaporator chamber by convective and conductive heating.
- 9. An oil reclamation device as recited in claim 8 wherein the oil containing contaminants flows via said oil inlet conduit to an inner side of said generally annular wall element.
- 10. An oil reclamation device as recited in claim 1 further comprising a filter canister housing extending from said evaporator head on the opposite side of said evaporator head from said evaporator base, said filter canister housing having a removable lid and enclosing an oil filter for filtering oil prior to the oil passing into said oil inlet conduit.
