Introduction of agitator types and installation methods of reactors
Stirrers, also called stirring paddles or impellers, are the key components of stirring equipment such as reactors. The main types are paddle, thrust, frame, turbine, screw, and ribbon. The design focus is on the installation method of the agitator and the structural design connected to the shaft.
Most of the blades of the mixer are two blades, which are divided into straight blade, inclined blade and curved blade. The ratio Dj / D1 of the diameter of the stirrer to the inner diameter of the tank is usually 0.35-0.8, which is mostly used in the case of n <100r / min. The paddle stirrer can be mounted on the shaft in single or multiple layers. The bottommost paddle is usually installed at the same level as the lower head weld. When the two-layer propeller is installed, the uppermost propeller is usually installed at the middle or slightly higher distance from the liquid surface to the bottom propeller.
