MIXING DEVICE Russian patent published in 1998 - IPC

FIELD: food, medical, microbiological and chemical branches of industry. SUBSTANCE: device has trough 1, frame 2, drive consisting of induction motor 3 attached to frame and connected to reduction gear 5 through coupling 4. Device has three input shafts. First shaft carries bevel gear-wheel 6 and crankshaft 7 which forms rotary kinematic pair "frame- crankshaft". Cylindrical gear 8 and auxiliary crankshaft 9 are secured on second drive shaft. Cylindrical gear-wheel 10 and bevel gear 11 are secured to third shaft. Output shaft of reduction gear is coupled to any one of shafts. Axes of revolution of the above-indicated crankshafts 7,9 form angle equal to angle between axes of the above-indicated bevel gear and bevel gear-wheel. Crankshaft 7 is coupled to stone 13 through ball kinematic pair with pin 12. Guide slot 14 serves as guide for stone 13 and forms ball- screw pair with the latter. Upper part is coupled to auxiliary crankshaft 9 through ball kinematic pair 16. EFFECT: intensification of mass-transfer and heat-exchange processes, balancing of concentrations and temperature over entire volume of liquid. 1 dwg
