  • Impeller assembly for dispersing solid in liquid utilizing curved baffle plate and solid-liquid mixing device using impeller assembly
    Patent number: 12311325
    Abstract: An impeller assembly for a solid-liquid mixing device, which includes an impeller body, multiple mixing blades which are evenly distributed on the inner side of the impeller body and extended outwards from the shaft of the impeller body, and at least two baffle plates being disposed on the outer side of the impeller body along a radial direction thereof outwards and disposed in the circumferential direction of the impeller body. At least one pair of adjacent two baffle plates satisfies following conditions: curves projected by two opposite surfaces of each of adjacent baffle plates on a cross section of the impeller at any height are smooth curves, and at least one of the curves is not fully included in a circle with the center of the shaft as its center.
