Abstract 

The object of this design is the design of axial flow type mixer structure, used for mixing sterile liquid. Design of axial flow type mixer is mainly the design of mechanical structure as the main mixing objects, three-dimensional modeling, the checking calculation, motion simulation, virtual assembly, flow field simulation.

The design of the overall structure consists of several modules, power device, a stirring device, lifting device, sealing device, stabilizing device. The power device comprises a motor shaft, coil, magnet. The stirring device comprises a bearing ring, bearing ring, mixing blades. Lifting device comprises a shaft pin, bearing bushing limit screw. Stable device comprises a positioning card, a stirring shaft, positioning bar, the supporting rod element.

Axial flow agitator drives the stirring blade to rotate by the motor, so as to realize the mixing function. First the structure and size of the main components of the design in the design, then the flow field simulation, checking its strength according to the simulation results, according to the calculation results to the choice of materials. Axial flow type mixer for mixing two or more than two kinds of solid or liquid and make its are mixed evenly, can be widely used for mixing of sterile liquid.

Keywords: Axial flow type mixer; power device; stirring device; stabilizing device
