Abrégé
An impeller assembly (10) used for a solid-liquid mixing device. The impeller assembly comprises an impeller body (101), several evenly distributed mixing blades (102) located on the inner side of the impeller body (101) and axially extending outwards, and at least two layers of baffle plates (103) disposed on the outer side of the impeller body (101) along the radial direction thereof outwards and in the circumferential direction. One of two adjacent baffle plates (103) is fixedly connected to a cavity (105) of the mixing device, the other one is fixedly connected to the impeller body (101), and at least one pair of adjacent baffle plates (103) satisfies the following conditions: on a cross section of any height, curves corresponding to two opposite surfaces of the adjacent baffle plates (103) are both smooth curves, and the curve corresponding to at least one surface does not all fall on the same circle with an axis center as the center of the circle. When the impeller body (101) rotates, a gap between the pair of adjacent baffle plates (103) changes periodically. The shearing strength and the retention time are both taken into consideration when the impeller assembly (10) operates, a strong shear effect is achieved on a solid-liquid mixture, liquid static pressure changes can be caused to generate microbubbles, and the dispersion efficiency of solid in liquid in improved.
