WORKING TOOL OF MIXER Russian patent published in 1995 - IPC

FIELD: chemical industry. SUBSTANCE: working tool of mixer is composed of two shafts placed in parallel which carry blades. Blades are manufactured in the form of closed one-sided surfaces of Mobius strips. Developments of Mobius strips on plane perpendicular to shafts axes present specularly reflected S-shaped elements. One element is anchored with central section on upper end of shaft perpendicular to its axis and its butts on lower end of shaft in parallel to its axis. The other element is fixed with central section on lower end of shaft perpendicular to its axis and its butts on upper end of shaft in parallel to its axis. Blades may be put on shafts with displacement H=(1-3)Д_b relative to each other, where Д_b is biggest dimension of blade in plane perpendicular to shaft axis. EFFECT: increased mixing efficiency of working tool. 2 cl, 11 dwg
