Abstract
Abstract A device for separating components from a carrier liquid, comprising mutually parallel corrugated plates, troughs or similarly shaped surfaces, delimiting therebetween separation passages, the longitudinal axes of which corrugations or the like which determine the direction of removal of the separated components include an angle with the direction of the supply and discharge flow of the liquid, in order to obtain an optimal separation between the liquid flow and the flow of the separated components to be removed from the device.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
240 words
A device for separating components from a carrier liquid, which components have a specific mass differing from that of the carrier liquid, comprising a tank including a supply chamber for the liquid to be treated, a discharge chamber for the treated liquid, and at least one collecting duct for components separated from the carrier liquid; at least one plate assembly located in said tank between said supply chamber and said discharge chamber and including a plurality of spaced, substantially parallel plate means defining a plurality of separation passages which extend from one end of said plate means communicating with said supply chamber to the opposite end of said plate means communicating with said discharge chamber and through which the liquid being treated is guided from said supply chamber towards said discharge chamber; said plate means having at least one side communicating with said collection duct and including means defining a plurality of substantially parallel, trough-like collection passages which extend transversely of the flow direction of the liquid being treated and toward said collection duct and which are adapted to collect the components separated in respective of said separation passages and guide the thus-collected components toward said collection duct substantially out of contact with the liquid flow through said separation passages; and said plate means being inclined from the horizontal less than 90* so as to promote the movement of the collected components through said collection passages towards said collection duct.
Claim 2
Independent Claim
240 words
A device for separating components from a carrier liquid, which components have a specific mass differing from that of the carrier liquid, comprising a tank including a supply chamber for the liquid to be treated, a discharge chamber for the treated liquid, and at least one collecting duct for components separated from the carrier liquid; at least one plate assembly located in said tank between said supply chamber and said discharge chamber and including a plurality of spaced, substantially parallel plate means defining a plurality of separation passages which extend from one end of said plate means communicating with said supply chamber to the opposite end of said plate means communicating with said discharge chamber and through which the liquid being treated is guided from said supply chamber towards said discharge chamber; said plate means having at least one side communicating with said collection duct and including means defining a plurality of substantially parallel, trough-like collection passages which extend transversely of the flow direction of the liquid being treated and toward said collection duct and which are adapted to collect the components separated in respective of said separation passages and guide the thus-collected components toward said collection duct substantially out of contact with the liquid flow through said separation passages; and said plate means being inclined from the horizontal less than 90* so as to promote the movement of the collected components through said collection passages towards said collection duct.
Claim 3
Dependent Claim
66 words
A device according to claim 1 including a plurality of spaced baffles located in said collecting duct adjacent to a side of said plate means and extending transversely of the flow direction of the liquid being treated and substantially parallel to the longitudinal axes of said collection passages for minimizing the passage of the liquid being treated from said separation passages directly into said collection duct.
Claim 4
Dependent Claim
34 words
A device according to claim 1 including a baffle partially covering the portion of one end of said plate means and thereby closing the ends of said separation passages adjacent to said collection duct.
Claim 5
Dependent Claim
139 words
A device according to claim 1 wherein the liquid being treated includes first and second components one having a specific mass higher than that of the carrier liquid and the other having a specific mass lower than the carrier liquid, and wherein said plate means includes first and second sections located in series with respect to the direction of the liquid flow through said separation passages, the collection passage defining means of said first section adapted to primarily guide the first components separated from the liquid being treated towards a first collection duct located in communication with one side of said plate means and the collection passage defining means of said second section adapted to primarily guide second component separated from the liquid towarDs a second collection duct located in communication with the opposite side of said plate means.
Claim 6
Dependent Claim
38 words
A device according to claim 4 including a means for introducing an agent, which promotes separation of the second component from the carrier liquid, into the liquid being treated at a location between said first and second sections.
Claim 7
Dependent Claim
45 words
A device according to claim 1 wherein said tank includes an outer wall having a circular cross section and said plate assembly being arranged in a fan-like array with the plate means in rotational symmetry along said wall and being directed transversely to said wall.
Claim 8
Dependent Claim
64 words
A device according to claim 1 including a plurality of said plate assemblies arranged in juxtaposed relationship within said tank, said plate assemblies being mutually separated by a collecting duct, said plate means being superposed, and said collecting ducts being separated from said supply chamber by baffles which guide the liquid being treated towards the inlet of said separation passages of said plate assemblies.
Claim 9
Dependent Claim
29 words
The device according to claim 7 wherein the distance between the sides of said plate means gradually increase in the flow direction of the liquid through said separation passages.
Claim 10
Dependent Claim
39 words
The device according to claim 7 including longitudinal partitions located in each of said collecting ducts adjacent to one side of said plate means and extending substantially parallel to the flow direction of the liquid through said separation passages.
Claim 11
Dependent Claim
72 words
The device according to claim 7 wherein the adjacent plate assemblies are arranged with the incline of said plate means of one being symmetrically opposed to the incline of said plate means of the other; and wherein the arrangement of the collection passage defining means of the plate means of each of said plate assemblies are arranged in a mirror symmetry with the corresponding collection passage means of the adjacent plate assembly.
Claim 12
Dependent Claim
67 words
A device according to claim 10 including a collection vessel communicating with one end of said collection duct; and substantially parallel, spaced guiding partitions located in each of said collection ducts for guiding separated components collected in said collection ducts towards said collecting vessel, said guiding partitions extending between the adjacent sides of the plate means of adjacent assemblies in alignment with corresponding collecting passage defining means.
Claim 13
Dependent Claim
29 words
A device according to claim 11 wherein the distance between the sides of said plate means gradually increases in the flow direction of the liquid through said separation passages.
Claim 14
Dependent Claim
15 words
A device according to claim 12 wherein said guiding partitions have a trough-like cross section.
Claim 15
Dependent Claim
44 words
A device according to claim 7 wherein said plate means of said plate assembly includes two sections which are inclined towards each other in the form of an inverted V with respect to the flow direction of the liquid flowing through said separation passages.
Claim 16
Dependent Claim
23 words
A device according to claim 14 wherein the adjacent lateral sides of said plate means section are spaced apart to define openings therebetween.
Claim 17
Dependent Claim
