Abstract
A rotary processor useful in mixing, conveying, and heating or cooling a fluid material. Interchangeable subassemblies each comprise a helical coil permanently affixed at each end to a terminal block. The terminal blocks of each subassembly are removably fastened at a preselected orientation to two polygonal segments of a rotatable shaft. The polygonal segments are rotated relative to one another. A portion of the shaft and the subassemblies are supported within a housing having an inlet and an outlet for flow of the material to be processed.
Claims4
A fluid material rotary processor comprising:
- a plurality of interchangeable subassemblies, each said subassembly including two terminal blocks and a helical coil having two ends, each of said ends being sealingly and permanently affixed within one of said terminal blocks, each said coil having a coil axis;
- a shaft including a shaft axis, a first segment and a second segment, said segments each having exterior edges forming in cross section a polygon, said edges of said first segment being angularly offset with respect to said edges of said second segment, said axes of said coils being parallel to said shaft axis;
- means for removably mounting said subassemblies to said edges of said segments such that said coils are mounted aside said shaft and certain of said subassemblies are axially staggered along said shaft with respect to other of said subassemblies;
- a housing having a fluid material inlet and outlet;
- means for supporting and rotating said segments and affixed subassemblies within said housing;
- said coils entering said terminal blocks at an entry angle with respect to said shaft axis, said entry angle being equivalent to the helix angle of said respective coil, and said certain subassemblies being staggered along said shaft with respect to other of said subassemblies by a distance equivalent to the pitch of said coils divided by the number of said subassemblies.
