Abstract:
1. A homogenizing mixer comprising: a fixed frame that is disposed so as to be fixed at the bottom of a container, and communicates from the inside of the container; an agitating unit that is disposed in the fixed frame so as to be lifted up and down by medium of a lifting unit, and that agitates materials contained in the container; a driving unit that is disposed on the bottom of the agitating unit for transferring a rotational driving force for the agitating unit; and a discharging unit that is coupled to the agitating unit and discharging a homogenized material to the outside of the mixer, wherein the agitating unit comprises: a moving frame that is disposed in the inside of the fixed frame so as to be lifted; an impeller that is rotatably disposed in the moving frame and has a number of blades; an agitating shaft that is coupled with the impeller and is connected with the driving unit, to thereby provide a rotational force; and a coupling unit that is disposed between the agitating shaft and the driving unit, and transfers the rotational force for the agitating shaft, wherein the impeller comprises: a rotating impeller having a hollow cylindrical body, so as to be coupled with one end of the agitating shaft, a plurality of outer blade members that are formed on the outer circumference of the cylindrical body and are spaced apart from each other, and a plurality of inner blade members that are formed to be spaced apart inwards from the outer blade members and whose cross-section have a triangular shape, respectively; and a fixed impeller having a hollow cylindrical body, so as to be coupled with the rotating impeller, a plurality of outer fin members that are protrudingly formed from the outer edge of the cylindrical body and that enclose the outer blade members when the fixed impeller is coupled with the rotating impeller, and a plurality of inner fin members that are formed to be spaced apart inwards from the outer fin members and are disposed in a space formed between the outer blade members and the inner blade members when the fixed impeller is coupled with the rotating impeller.
