Typical runoff paddle, suitable for mixing, extraction, emulsification, solid suspension, dissolution, bubble dispersion, absorption, etc.
Advantages: Strong shear, wide application range, the presence of discs facilitates the processing of small-scale stirrers
Disadvantages: high energy consumption, large drop in stirring power during ventilation
Common medium viscosity range: (straight leaf: <5x100000mpa.s) (oblique/bending leaf: <100000mpa.s)
Common rotation speed: 10~300r/min
Leaf tip speed: (straight/bending: 1~5m/s) (oblique leaf: 2~6m/s)
Fluid state: radial flow in straight blades and curved blades. When there is a baffle, the upper and lower two circulation flows are formed by the blade, and the axial diversion of the inclined blade is formed.
Remarks: The maximum speed can reach 600r/min
Application example: It is widely used in gas-liquid stirring devices, such as fermentation tanks, carbonization towers, hydrogenation kettles, etc.
