Agitator blade type: axial flow type: propulsion type, anchor type, ribbon type, screw type, frame type; mixed type includes: folding blade type, six-fold blade opening type turbine type, anchor blade combination type, general energy , six-blade disc turbine, six-fold leaf disc turbine, vane; runoff type: straight blade paddle, three-blade swept, serrated disc, six straight blade open turbine, rear The curved blade opens the turbine type, the flat leaf disc turbine type, the Bulma gold type, the rear curved leaf disc turbine type, and the six arc leaf disc type turbine type.
Paddle stirrers are mainly used for fluid circulation and cannot be used for gas-liquid dispersion operations. The folding leaf type consumes less power than the flat leaf type, and the operating cost is low, so the folding blade paddle is used more.
The turbine agitator is suitable for a wide range of material viscosity, large shear force and good dispersion of fluid. Straight and curved blade turbine mixers primarily produce radial flow, and the blade turbine agitators primarily produce axial flow.
The characteristics of anchor stirrer and frame stirrer: simple structure, convenient manufacture, suitable for materials with large viscosity and large processing capacity. Surface heat transfer coefficient. Can reduce the occurrence of wall hanging.
The agitator can be selected according to the nature of the medium, the characteristics of the reaction process, the stirring effect and the stirring power requirements.
