Agitators are generally classified into the following categories: 1. the propeller type stirrer is composed of 2-3 propelling type propeller blades, the working rotating speed is high, and the peripheral speed of the outer edge of each blade is generally 5-15 m/s. Propeller stirrers cause mainly axial flow, produce large circulation volumes, and are suitable for stirring low viscosity (<2Pa · s) liquids, emulsions and suspensions with a solids content of less than 10%. The rotating shaft of the stirrer may be inserted into the groove horizontally or obliquely, and the liquid circulation loop is asymmetric, resulting in increased turbulence and no depression of the liquid surface. 2. The turbine agitator is composed of 2-4 straight or curved blades mounted on a horizontal disc. The ratio of the outer diameter, the width and the height of the blade is generally 20:5:4, and the peripheral speed is generally 3-8 m/s. The turbine causes highly turbulent radial flow when rotating, suitable for dispersion and liquid-liquid phase reaction processes of gases and immiscible liquids.

The blades of the pitched blade agitator are turned at 45 ° or 60 ° in opposite directions, thus creating axial fluid flow. The paddle type stirrer is simple in structure and is commonly used for mixing of low-viscosity liquid and dissolving and suspending solid particles. 4. The shape of the outer edge of the anchor type stirrer blade is consistent with that of the inner wall of the stirring tank, only a small gap is reserved between the outer edge and the inner wall, and the viscous reaction products attached to the tank wall or the solid matters accumulated at the tank bottom can be removed, so that a good heat transfer effect is kept. The peripheral speed of the outer edge of the blade is 0.5-1.5 m/s, and the stirring blade can be used for stirring Newtonian fluid and pseudoplastic fluid with the viscosity of 200 Pa.s (see viscous fluid flow, when only high-viscosity liquid is stirred, a larger stagnation area is arranged in a liquid layer, 5, the outer diameter and the screw pitch of a screw belt of the screw belt type stirrer are equal, and the stirring blade is specially used for stirring the high-viscosity liquid (200-500 Pa.s) and the pseudoplastic fluid and is usually operated under the laminar flow state.
