Abstract
Abstract There is disclosed a manifold assembly for a rotary solvent extractor formed of an elongated fluid distribution trough or conduit divided into a plurality of fluid distribution subsections by intermediate gate members wherein each fluid distribution subsection is in fluid communication with a fluid supply conduit. A deflector plate is disposed therebelow beneath a manifold assembly to permit for the adjustment of the angle of fluid discharge.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
In a solvent extractor including a vessel having a plurality of cells formed by a plurality of radially extending walls arranged in circumferential fashion on a generally horizontal plane around a vertical extending rotor, a feed conduit for introducing solids to be treated into said cells, a solids-retaining bottom closure for each of said cells, a track to maintain said bottom closures in substantially closed position during a predetermined section of a rotational path of each of said cells, fluid manifold assemblies for successively introducing a solvent into said cells from above said predetermined section of said rotational path, liquid collection zones disposed beneath said cells and including a plurality of compartments for receiving liquid, an improved fluid manifold assembly, which comprises: an elongated substantially horizontally-disposed conduit member having an overflow wall member, a plurality of vertically-disposed gate member with said conduit member thereby dividing said conduit member into plurality of sub-zones; conduit means for introducing a fluid into said sub-zones of said conduit member; and means for moving said gate members from within said conduit member.
Claim 2
Dependent Claim
177 words
In a solvent extractor including a vessel having a plurality of cells formed by a plurality of radially extending walls arranged in circumferential fashion on a generally horizontal plane around a vertical extending rotor, a feed conduit for introducing solids to be treated into said cells, a solids-retaining bottom closure for each of said cells, a track to maintain said bottom closures in substantially closed position during a predetermined section of a rotational path of each of said cells, fluid manifold assemblies for successively introducing a solvent into said cells from above said predetermined section of said rotational path, liquid collection zones disposed beneath said cells and including a plurality of compartments for receiving liquid, an improved fluid manifold assembly, which comprises: an elongated substantially horizontally-disposed conduit member having an overflow wall member, a plurality of vertically-disposed gate member with said conduit member thereby dividing said conduit member into plurality of sub-zones; conduit means for introducing a fluid into said sub-zones of said conduit member; and means for moving said gate members from within said conduit member.
Claim 3
Dependent Claim
29 words
The apparatus as defined in claim 1 wherein said means for moving said gate members includes a shaft on which said gate members are mounted for substantially vertical rotation.
Claim 4
Independent Claim
51 words
The apparatus as defined in claims 1 or 2 wherein said conduit member is formed of an overflow wall, a bottom wall, a back wall, a top wall and an intermediate wall position extending downwardly from said top wall to a point above said bottom wall thereby defining a fluid passageway.
Claim 5
Dependent Claim
19 words
The apparatus as defined in claim 3 wherein fluid conduits are positioned in said top wall above said subzones.
Claim 6
Dependent Claim
20 words
The apparatus as defined in claim 3 wherein said shaft is mounted to a lever member external of said vessel.
Claim 7
Independent Claim
55 words
The apparatus as defined in claims 1, 2, 4 or 5 and further comprising a substantially flat fluid deflector plate disposed below and co-axially with said conduit member, said fluid deflector plate being mounted on a shaft; and means connected to said shaft to effect predetermined rotation of said fluid deflector plate about said shaft.
