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. Features of this invention include an improved filter assembly, an inside sealing mechanism for flow control, a wall guide mechanism to maintain proper flow control, an improved heat transmitting element, an oil inlet metering assembly and an improved evaporator plate.
Claims28
An oil reclamation device having a longitudinal axis and comprising:
- (a) a housing means having a container, a cover means, an oil inlet, an oil outlet means and a vapor removal vent means,
- (b) filter means and evaporator plate means disposed in said container, said filter means including rigid canister means having an upper peripheral edge,
- (c) heating means attached to said cover means,
- (d) said evaporator plate means including an upper and a lower side, said upper side having a vaporizing surface along which oil passes in a thin film and said lower side facing downwardly toward said canister means,
- (e) said cover means including a heat transmitting member and defining an evaporation chamber between the cover means and the evaporator plate means,
- (f) said lower side of the evaporator plate means including an annularly disposed outer peripheral seat for receiving resilient sealing means disposed between the evaporator plate means and the canister means, said sealing means being located along the entire periphery of the evaporator plate means to prohibit bypassing of fluids between the plate means and the container,
- (g) said evaporator plate means including passageway means extending from the filter means to deliver substantially all of the oil being treated into said evaporation chamber in a thin film along the vaporizing surface, and
- (h) fastening means for resiliently securing the cover means to the top of the container against the resilience of the sealing means,
- (i) a portion of the inside of the cover means being in contact with a portion of the upper side of the evaporator plate means to sealingly urge the evaporator plate means against the filter means with said resilient sealing means therebetween.
