Abstract
A system for separating a mixture of two fluids of different specific gravities comprising: a first chamber having an inlet for receiving said mixture; a second chamber having a connection for receiving the fluid with the higher specific gravity of said mixture from said first chamber, said connection being situated between a portion of the two chambers below the inlet; and a waste outlet in said first chamber to drain residue situated at an interface between the two fluids.
Claims23
A separation method comprising:
- directing a mixture of two fluids exhibiting different specific gravities into a separator in a printing system;
- separating the two fluids;
- and
- draining a residue containing waste and/or contaminants and situated at an interface between the two fluids from a waste outlet provided to the system.

A separation method comprising:
- directing a mixture of two fluids through an inlet into a first chamber of a separator in a printing system, the two fluids exhibiting different specific gravities;
- separating the mixture in the first chamber into a lighter fluid having a lower specific gravity, a heavier fluid having a higher specific gravity, and a residue situated at an interface between the two fluids in the first chamber;
- directing the heavier fluid from the first chamber through a connection into a second chamber, the connection being situated between a portion of the two chambers below the inlet into the first chamber;
- venting built up pressure from a top of the first chamber above the inlet and from a top of the second chamber, the venting being to atmospheric pressure or between the first and second chamber;
- and
- draining the residue in the first chamber through a waste outlet from the first chamber.
3 more elements
A separation method comprising:
- evaporating a carrier liquid from a printing engine in an enclosure of a printing system;
- condensing the evaporated carrier along with water from airborne moisture in the enclosure;
- directing a mixture of the condensed carrier and the condensed water through an inlet into a first chamber of a separator in the printing system, the carrier and the water exhibiting different specific gravities;
- separating the mixture in the first chamber into the carrier, the water, and a residue situated at an interface between the carrier and the water in the first chamber;
- directing the water from the first chamber through a connection into a second chamber, the connection being situated between a portion of the two chambers below the inlet into the first chamber;
- and
- draining the residue in the first chamber through a waste outlet from the first chamber.
