  • Patent number: 12325009
    Abstract: The present application discloses an impeller assembly and a mixing apparatus, and relates to the technical field of solid and liquid mixing devices. The impeller assembly includes an impeller structure and a housing structure. The impeller structure includes a body, and a surface of the body is provided with a plurality of backward-skewed blades. A blade angle of each backward-skewed blade on any flow plane first decreases progressively and then increases progressively from an inlet to an outlet. A first baffle is disposed on a lower portion of the body. The housing structure includes a second baffle. The first baffle is provided with first guide slots, and the second baffle is provided with second guide slots. A fluid enters from the inlet at an upper portion of the body, flows along the surface of the body, and flows out through the outlet at a lower portion of the body and through the first guide slots and the second guide slots.
