Baffle for improving stirring shearing rate

The utility model discloses a baffle capable of improving the stirring shear rate. The baffle comprises a baffle body arranged in a stirring tank provided with a stirring shaft and an impeller. The stirring shaft drives the baffle body or the impeller to rotate, and correspondingly, the impeller or the baffle body is fixed in the stirring tank body; a receding groove is formed in the position, corresponding to the impeller, of the baffle body. Materials are sheared through relative rotation between the baffle body and the impeller; under the action of the receding groove, the baffle body is attached to the impeller as much as possible in the radial direction, so that the combination face of a stirring movable area and a stirring static area is increased, the stirring shear rate is increased, and the flow pattern can be changed under the working condition of high-viscosity laminar flow. Under the same stirring condition, the baffle body in the arrangement mode can enable the particle size of materials to be sm
