MIXER FOR VISCOUS-FLOW DISPERSED SYSTEMS Russian patent published in 2016 - IPC B01F7/16 B01F7/30 

FIELD: machine building.

SUBSTANCE: invention relates to mixing of powders, and more specifically to mixing devices with rotating around vertical axis mixers inside stationary tank with viscous flow material structural homogenisation of powdered components, and can be used for preparing pyrotechnic mixtures containing polymer binder with process volatile solvent. Mixer of viscous-flow dispersed systems contains mounted on common bed high-speed and low-speed drives connected by means of gear transmissions through vertically movable gear adjoining process bowl with rotation axes of frame and stirring device. Novelty is that high-speed drive through central shaft is connected directly with axis of rotation of stirring device made in form of turbine and low-speed drive by means of worm gear and coaxial carrier kinematically connected to bearing axis of rotation of frame blade satellite internal engagement gear with wheel planetary mechanism, which on opposite side is connected with additional servo drive reversible rotation frame blade.

EFFECT: invention ensures universality of mixer for preparation of loose and viscous-flow powder mixes with plasticising binder, which automatically is adapted to varying in process of mixing process rheology of dispersed system.
