Process for erecting a rotor assembly for a rotary extractor and apparatus therefor

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.
