Abstract

The invention belongs to the technical field of agitating devices, and relates to an agitator paddle. The agitator paddle comprises a wheel hub, wherein at least two groups of paddle connection blocksare uniformly distributed on the circumferential surface of the wheel hub, each paddle connection block is fixedly connected with a main paddle, a upstream face is formed on outer end side part of the main paddle, the upstream face is of a chamfered surface structure, and a secondary paddle is arranged at the side, far from the upstream face, of the outer end surface of the main paddle. Due to the paddle, flows caused by the paddle and a paddle system can be turbulent flow and transition flow state, so that the paddle is very suitable for mixing, solid-liquid suspending, dissolving, heat transmission, reacting and crystalizing of medium and low viscosity liquid. Compared with a traditional impeller of open turbine, the agitator paddle improves the efficiency by 50%, or lowers the energy consumption by 40% under the same agitation effect.

Description

technical field [0001] The invention belongs to the technical field of stirring equipment, and relates to a stirrer impeller. Background technique [0002] The high efficiency of the mixer has always been the goal pursued by the mixing business. The agitator is an important part of the mixing equipment. A good agitator can greatly improve the mixing efficiency, shorten the reaction time, increase the yield of finished products, and improve product quality. The impeller is an important component of the agitator, and the existing impeller structure cannot make the flow in a turbulent or transitional flow state. Contents of the invention [0003] In view of the above problems, the present invention provides an agitator impeller, which makes the flow formed by the impeller and the impeller system be in a turbulent, transitional flow state, and is very suitable for mixing of medium and low viscosity liquids, solid-liquid suspension, dissolution, Heat transfer, reactions and c...
