METHOD AND DEVICE FOR MIXING Russian patent published in 2003 - IPC

FIELD: mixing of liquids ort liquid with particles without liquid aeration. SUBSTANCE: liquid and/or particles fill the vessel having upper end, lower end and restricting wall built-in between upper and lower ends. Mechanical rotating device (turbine) located near upper end and immersed in liquid is used for producing vortex flow directed radially from central part of vessel towards restricting wall for formation of vortex flow. Flow is distinguished by its peripheral circular region with moderate vortex flow along restricting wall, moving from upper end to lower end and directed inside flow, near lower end of vessel and internal ring of vortex flow near central region of vessel. Internal circular flow moves from lower end to upper end and traverses path from lower end of vessel to mechanical rotating device. EFFECT: reduced energy consumption, increased efficiency. 35 cl, 6 dwg
