Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
198 words
Apparatus for continuously separating liquid phases comprising: a basin for receiving mixed phase liquids and in which the phases separate to upper and lower layers, said basin having an imperforate bottom and sides and further having first and second outlets in opposite sides thereof for the upper and lower layers, respectively, said outlets determining opposite, horizontal, parallel flow directions for the upper and lower layers; a plurality of partition walls within the basin, said partition walls being transverse to the flow direction and spaced apart in the flow direction, said partition walls having opposite end edges in sealing contact with respective sides of the basin, and drive means for moving the partition walls relative to the basin such that adjacent partition walls can be lifted and lowered in an opposite sense and such that adjacent partition walls can be moved toward and away from each other, said partition walls having lower edges which, in the lowered position of the respective partition wall, sealingly engage the bottom of the basin and which, in the raised position of the respective partition wall, are spaced from the bottom of the basin to provide a free flow cross-section for the lower layer.
Claim 2
Dependent Claim
198 words
Apparatus for continuously separating liquid phases comprising: a basin for receiving mixed phase liquids and in which the phases separate to upper and lower layers, said basin having an imperforate bottom and sides and further having first and second outlets in opposite sides thereof for the upper and lower layers, respectively, said outlets determining opposite, horizontal, parallel flow directions for the upper and lower layers; a plurality of partition walls within the basin, said partition walls being transverse to the flow direction and spaced apart in the flow direction, said partition walls having opposite end edges in sealing contact with respective sides of the basin, and drive means for moving the partition walls relative to the basin such that adjacent partition walls can be lifted and lowered in an opposite sense and such that adjacent partition walls can be moved toward and away from each other, said partition walls having lower edges which, in the lowered position of the respective partition wall, sealingly engage the bottom of the basin and which, in the raised position of the respective partition wall, are spaced from the bottom of the basin to provide a free flow cross-section for the lower layer.
Claim 3
Dependent Claim
45 words
Apparatus as in claim 1 wherein said means for moving the partition walls includes means mounting each partition wall for pivotal movement about a horizontal axis which is transverse to said flow direction and further includes means for swinging the partition walls about said axes.
Claim 4
Dependent Claim
11 words
Apparatus as in claim 2 wherein the partition walls are planar.
Claim 5
Dependent Claim
38 words
Apparatus as in claim 2 wherein said means for swinging the partition walls includes two push rods and means for driving the push rods in opposite directions, every other partition wall being connected to a common push rod.
Claim 6
Dependent Claim
19 words
Apparatus as in claim 1 wherein the end edges and bottom edges of the partition walls carry sealing elements.
Claim 7
Dependent Claim
23 words
Apparatus as in claim 1 including supply means for supplying mixed phase liquid to the basin at a location centrally between said outlets.
Claim 8
Dependent Claim
37 words
Apparatus as in claim 1 wherein one of said outlets includes an underflow weir and an overflow weir for discharging the lower phase and wherein the other outlet includes an overflow weir for discharging the upper phase.
