The invention discloses a novel rigid and flexible combined stirring peddle for damaging a flow field isolation area. The novel rigid and flexible combined stirring peddle comprises a stirring shaft, rigid stirring paddles, a fixing device, lugs, welding pieces, rings and flexible ropes. The novel rigid and flexible combined stirring peddle mainly consists of the rigid stirring paddles and the welding pieces which are fixed on the stirring shaft, and the flexible ropes which are connected through the lugs and the rings. The rigid and flexible combined stirring peddle is driven by a motor to rotate inside a stirring tank, mechanical energy is input into fluid inside the stirring tank, then an appropriate fluid field is supplied to the fluid, and the fluid mixing process is intensified. By adopting the novel rigid and flexible combined stirring peddle disclosed by the invention, the resistance of blades of the rigid and flexible combined stirring peddle in the rotation process can be reduced, torque can be reduced, and power consumption can be reduced. Under the mutual action of the stirring paddle and materials, the flexible ropes can be shaken continuously or make multi-body movement, the 'sweeping area' of the blades can be increased, regular areas formed below and above the blades can be effectively 'cut off', the turbulence degree of the fluid inside the stirring tank can be increased, the energy conduction process is intensified, a mixing effect of the materials is improved, and the cost of the device can be reduced.
