Axial flow agitator is a mixing device that generates axial flow through rotating blades. Its core structure and working principle are as follows:
1、 Structural composition
1. Impeller system
Adopting a spiral or spatially twisted blade design, the blade cross-section is composed of curved and wavy curves, forming a twisted gradient structure along the central axis. Large equipment is usually equipped with hydraulic adjustment mechanisms to achieve dynamic adjustment of blade angles.
2. Drive device
Including motors, reducers, and hollow chrome plated pump shafts, large equipment adopts modular design to reduce weight.
3. Auxiliary components
The guide vanes are used to convert rotational kinetic energy, the suction pipe adopts a horn shaped or elbow shaped flow channel design, and the baffle is used to eliminate vortex effects.
2、 Working principle
By rotating the impeller, axial thrust is generated, creating fluid motion similar to that of a propeller. The liquid is pushed along the axis direction while generating radial turbulence, achieving efficient mixing. Its energy conversion efficiency is 20% -30% higher than traditional mixers, and its power accuracy is lower.
3、 Application Fields
1. Chemical and Pharmaceutical Industry
Used for polymerization reactions, desulfurization processes, and phosphoric acid extraction to solve the problem of low efficiency in traditional equipment.
2. Environmentally friendly water treatment
The implementation of solid suspension and heat transfer processes in large reaction vessels is particularly suitable for scenarios with low shear requirements.
3. Food industry
Used for liquid-liquid mixing and temperature homogenization, energy consumption is reduced by more than 30% compared to centrifugal equipment.
4、 Technical advantages
1. Energy saving: Variable cross-section blade design can reduce power consumption by 70% -80%.
2. Adaptability: Supports eccentric installation and side insertion, optimizing the mixing effect of large containers.
3. Maintainability: The modular structure facilitates quick replacement of blades, and the chrome plated shaft has strong corrosion resistance.
