| 摘要 | Method and apparatus for separating ink from pulped inked paper: a suspension of pulped paper and chemicals enters a cylindrical container tangentially near the container bottom and rotates around the interior of the container; the ink and chemicals form a foam that floats off the suspension of paper fibers; the suspension exits from the container tangentially near the container top; a funnel at the top of the container; a foam outlet near the axis of the container from the funnel; a vortex generator at the bottom of the container, which blows upwardly creating a vortex in the suspension; means disperse air in the suspension in the container inlet before the suspension enters the container through the container inlet; the dispersing means either comprises a rotor cooperating with a stator, or comprises deflector plates in the container inlet; air is supplied to the inlet at the dispersion means rotor or deflector plates; the deflector plates may be washed clean. | ||||||
