## Abstract

There is disclosed a rotor assembly for a rotary solvent extractor comprised of segmental inner, outer and side wall assemblies provided with positioning elements for facile field erection on support beams with the segmental inner, outer and side cell walls being prefabricated and shipped in stacked relationship to the job site for field erection.

## Claims

### Claim 1

In a rotary solvent extractor including a vessel having a vertically-disposed rotor from which there is radially-disposed a plurality of cells arranged in a circumferential manner on a generally horizontal plane wherein each of said cells is disposed between radially-extending upper and lower support beams members mounted to said vertically-disposed rotor and wherein each cell is open at the top and provided with a hinged screen bottom door member, an improved cell assembly, which comprises:
side wall members having a cell surface and a side wall mounting surface, said side wall mounting surface having upper and lower prefabricated horizontally-disposed mounting elements, said mounting elements being positioned and affixed to said upper and lower support beam members, respectively, said cell surface of said side wall members being provided with prefabricated upper and lower inner and outer positioning bar elements;
an inner wall member having a cell surface and disposed between said side wall members with respect to said upper and lower inner positioning bar elements thereof;
an outer side wall member having a cell surface and disposed between said side wall members with respect to said upper and lower outer positioning bar elements; and
a gable cap means disposed over paired side wall members of adjacent cells to direct liquid flow into respective cells thereof.

### Claim 2 (depends on 1)

In a rotary solvent extractor as defined in claim 1 wherein said upper and lower inner and outer positioning elements are vertically-disposed bar members.

### Claim 3 (depends on 1)

In a rotary solvent extractor as defined in claim 1 wherein said upper horizontally-disposed mounting elements of said side wall is a generally L-shaped longitudinally extending member having a horizontally-extending leg portion extending outwardly a distance greater than said lower horizontally-disposed mounting element.

### Claim 4 (depends on 1)

In a rotary solvent extractor as defined in claim 1 wherein said upper and lower support beam members and said upper and lower horizontally-disposed mounting elements include preformed orifices for appropriately positioning said side wall members with respect to said upper and lower support beams, respectively.

### Claim 5 (depends on 4)

In a rotary solvent extractor as defined in claim 4 wherein said gable cap means and said upper support beam members include preformed orifices for positioning said gable member with respect to said upper support beam member.
