Abstract
Oil filter elements are processed to be substantially free of oil and thus contamination by passage through a series of counterrotating nip rolls which squeeze the filter element media and carry the separated oil circularly to be doctored off opposite the nip and collected for recycle separate from the filter element media.

Apparatus for the low contamination recycling of oil filter elements comprising a frame, a sequence of counterrotating pairs of nip rolls supported within the frame in sequential relation, means to feed a continuing succession of oil containing oil filter elements to between said nip rolls for a series of sequential compressions transferring separated oil onto said nip rolls while passing said oil separated filter elements beyond said nip rolls to recycle, means diverting said separated oil off said nip rolls before recombination with filter elements between said nip rolls as said nip rolls rotate toward each other, and wall means defining below said sequence of nip rolls separate paths to recycle for oil separated filter elements and separated oil.
Apparatus for the low contamination recycling of oil filter elements comprising a frame having side, top and bottom walls, a vertical sequence of counterrotating pairs of nip rolls supported by the frame, means to feed a continuing succession of oil-containing oil filter elements downward through said frame top wall to between said nip rolls for a series of sequential compressions transferring separated oil onto said nip rolls while passing said oil separated filter elements beyond said nip rolls to recycle, and means diverting said separated oil off said nip rolls to recycle before recombination with filter elements between said nip rolls as said nip rolls rotate toward each other, said frame bottom wall defining separate paths to recycle for said oil separated filter elements and said separated oil.
Apparatus for the removal of oil from oil filter elements comprising a rigid frame of side, top, and bottom walls, a series of left and right nip rolls within said frame journaled by said walls for counterrotation to define a vertical series of nips adapted to squeeze filter elements to separate the oil therefrom, said frame top wall including means to drop filter elements into the uppermost of said nips, said frame bottom wall being apertured to pass oil separated filters dropped from the lowermost of said nips, said frame bottom wall surrounding said aperture being adapted to collect oil separated from said oil filters;
- left and right arrays of doctor blades supported on said frame for vertical movement to and from engagement with said nip rolls opposite said nips, said doctor blades acting to divert separated oil from said nip rolls being carried from the locus of said nips on said nip rolls to collection by said frame bottom wall for recycle.
Method for low contamination recycling oil filter elements, including feeding a succession of oil-containing filter elements to a sequence of nip roll pairs supported by a frame having a wall below said nip roll pairs, sequentially squeezing said filter elements to separate said oil from said filter elements, diverting separated oil from said nip roll pairs along a first path to recycle, and diverting oil-separated filter elements along a second path to recycle separate from said first path, said first and second paths being defined by said frame bottom wall.
