Abstract
An immersion-type dispersing apparatus comprises a body, a tubular outer stator connected to the body, and 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 extends into the annular treatment gap and separates the annular treatment gap into an outer gap portion and an inner gap portion. A drive shaft is mounted for rotation to rotate the rotor. An axial flow shaft extends into the inner stator for rotation therein. Axial flow blades are 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 is formed in the rotor and communicates 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 is formed in the inner stator for discharging the material to be treated. A separating member is disposed in the discharge port for separating the dispersion medium from the material to be trea…
