Efficient stirring device with rigid-flexible combined type stirring paddles

The invention relates to an efficient stirring device with rigid-flexible combined type stirring paddles. The efficient stirring device comprises a stirring shaft connected with a motor, a plurality of rigid-flexible stirring blades and a perforated flexible sheet. Compared with the prior art, cross sections, in a rotation direction, of the rigid-flexible combined type stirring paddles are reduced by perforating the flexible sheet, so that energy consumption of the paddles is reduced; moreover, the rigid stirring paddles have a cutting effect on fluid, and the perforated flexible sheet further has a disturbance effect and a jet-flow effect on the fluid, so that the perforated flexible sheet can generate much high-speed jet flow, velocity gradient of the fluid can be effectively increased, turbulent degree of a system is increased, a transmission process of paddle energy is strengthened, material mixing efficiency is improved, material mixing time is shortened, and a better material mixing effect is realized u
