Abstract:
An immersion-type dispersing apparatus comprising: a body; a tubular outer stator connected to the body; a tubular inner stator disposed in the tubular outer stator and forming with the tubular outer stator an annular treatment gap for containing a dispersion medium; a rotor extending into the annular treatment gap and separating the annular treatment gap into an outer gap portion and an inner gap portion; a drive shaft mounted for rotation to rotate the rotor; an axial flow shaft extending into the inner stator for rotation therein; a plurality of axial flow blades mounted on the axial flow shaft for rotation therewith to generate a circulation flow for circulating a material to be treated into and out of the treatment gap; a circulation port formed in the rotor and communicating the inner gap portion and the outer gap portion of the treatment gap to permit the material to be treated and the dispersing medium to flow to and from the inner and outer gap portions of the treatment gap; a discharge port formed in the inner stator for discharging the material to be treated; and a separating member disposed in the discharge port for separating the dispersion medium from the material to be treated.
