Abstract
Abstract A separating device comprising an assembly of sloping passages, in which components of a liquid moving through this assembly are separated therefrom, which components are separately removed at an extremity of this assembly. This assembly is composed of tubes, troughs or corrugated plates delimiting sets of plural passages connected by narrower channels, the liquid to be treated being supplied to one passage, and the separated components passing through a connected channel into another passage, from which it may be removed out of contact with the liquid. Special guiding partitions may be arranged at a discharge end of such an assembly for suppressing turbulences.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
228 words
A device for separating heavier and lighter components of a mixture of substances including a carrier liquid comprising: a separation basin having a supply chamber into which the mixture to be separated is introduced and a discharge chamber separated from said supply chamber for collecting the lighter portion separated from said mixture; and at least one separation assembly, positioned in said basin between said supply chamber and said discharge chamber, through which said mixture flows to separate said components, said separation assembly including means defining at least one set of generally tubular and substantially parallel separating passages extending between said supply and discharge chambers and inclining towards said discharge chamber at an acute angle to the horizontal, each of said sets comprising a first separating passaGe and at least one second separating passage which are positioned at different heights, and means defining a passage connecting said first and second separating passages of each set through which a separated portion of said mixture passes from one of said separating passages to the other, said connecting passage extending over substantially the entire length of said separating passages and having a cross-sectional area smaller than that of at least one of said separating passages so as to substantially isolate said separated portion in one of said separating passages from the turbulence of the flow in the other of said separating passages.
Claim 2
Independent Claim
228 words
A device for separating heavier and lighter components of a mixture of substances including a carrier liquid comprising: a separation basin having a supply chamber into which the mixture to be separated is introduced and a discharge chamber separated from said supply chamber for collecting the lighter portion separated from said mixture; and at least one separation assembly, positioned in said basin between said supply chamber and said discharge chamber, through which said mixture flows to separate said components, said separation assembly including means defining at least one set of generally tubular and substantially parallel separating passages extending between said supply and discharge chambers and inclining towards said discharge chamber at an acute angle to the horizontal, each of said sets comprising a first separating passaGe and at least one second separating passage which are positioned at different heights, and means defining a passage connecting said first and second separating passages of each set through which a separated portion of said mixture passes from one of said separating passages to the other, said connecting passage extending over substantially the entire length of said separating passages and having a cross-sectional area smaller than that of at least one of said separating passages so as to substantially isolate said separated portion in one of said separating passages from the turbulence of the flow in the other of said separating passages.
Claim 3
Dependent Claim
53 words
A device according to claim 1 wherein the means defining said separating passages are arranged to define a plurality of vertically spaced sets of said separating passages and are further arranged so said first and second separating passages are respectively superposed to form a plurality of separate and alternate vertical rows of each.
Claim 4
Dependent Claim
30 words
A device according to claim 2 wherein said means defining said separating passages comprise oppositely directed open troughs which are arranged so the longitudinal edges thereof define said connecting passage.
Claim 5
Dependent Claim
27 words
A device according to claim 3 wherein the longitudinal edges of said troughs are mounted in spaced relationship so as to define the narrow flow passage therebetween.
Claim 6
Dependent Claim
54 words
A device according to claim 2 wherein the means defining said separating passages comprise vertically spaced and parallel corrugated plates which are arranged so the cross-sectional area defined between the superposed valleys and tops of adjacent plates are considerably larger than the cross-sectional area defined between a valley and a top of adjacent plates.
Claim 7
Dependent Claim
34 words
A device according to claim 1 wherein said means defining said separating passages are arranged so that the cross-sectional area of said separating passages gradually increases in one direction along the longitudinal axis thereof.
Claim 8
Dependent Claim
31 words
A device according to claim 6 wherein the direction of the cross-sectional area increase of one of said separating passages is opposite to that of the other of said separating passages.
Claim 9
Dependent Claim
64 words
A device according to claim 1 wherein the means defining said separating passages are arranged to define the plurality of vertically spaced sets of said separating passages and are further arranged so that said first and second separating passages are obliquely superposed to form a plurality of separate and alternate rows of each which are arranged at an angle with respect to the vertical.
Claim 10
Dependent Claim
30 words
A device according to claim 8 including duct means connected at one end of said separating passage interconnecting the oblique rows of one of said separating passages in liquid communication.
Claim 11
Dependent Claim
112 words
A device according to claim 8 wherein the means defining said separating passages are vertically spaced and parallel corrugated means, said corrugated means being arranged so that the corresponding corrugations of two successive superposed corrugations are in close relationship with each other at one side and define a connecting passage between the top and valley thereof at the other side, and further includes a plurality of alternate guiding partitions which are connected to one end of said separating passages so that alternate of said guiding partitions respectively interconnect said corrugated means at points where the corrugations are closest to each other and cross corresponding connecting passages defined by said tops and valleys.
Claim 12
Dependent Claim
81 words
A device according to claim 8 wherein said first and second separating passages are conically converging and are arranged with opposite conicity so that, at one end of said assembly, the openings of the separating passages having a smaller cross-section are symmetrically surrounded by separating passages having openings with a larger cross-section; and including a plurality of parallel, sloping guiding partitions connected to one end of said assembly and interconnecting passages having openingS with the smaller cross-sectional area in liquid communication.
Claim 13
Dependent Claim
26 words
The device according to claim 1 wherein said separating passages are arranged to have rotational symmetry with respect to the central vertical axis of said basin.
Claim 14
Dependent Claim
37 words
The device according to claim 12 wherein said means defining said separation passages are oppositely directed, open troughs with the troughs defining at least one of said separating passages being in a form of a truncated cone.
Claim 15
Dependent Claim
47 words
The device according to claim 12 including a cylindrical partition dividing said supply and discharge chambers, and a plurality of said separating assemblies having separating passages of the same length and arranged in said basin so the vertical planes intersecting the opposite ends thereof define co-axial cylinders.
