Definitions

  • a cause of loss of efficiency in the cleaner has been known to lie in the overflow nozzle.
  • Eddy currents form in the region of the inlet and move along the overflow nozzle :to the entrance end thereof where portions of the currents are dnawn into the nozzle and carried out with the accepted fraction and before the cleaner has had opportunity to separate out rejectable material.
  • the nozzle serves in this connection as a vortex finder, its inner end extending inwardly of the shell to receive the inner vortex and to conduct it out of the shell, the outer end of the nozzle being adapted for connection in a suitable conduit to conduct the materials caught in the inner vortex to a subsequent process step.
  • relatively light and clean fibers from the liquid pulp suspension are gathered up by the inner vortex and lconducted out the base end of the device as the accepted fraction while the remainder of the liquid suspension leaves the device through the apex end thereof. As shown in FIG.
  • an overflow nozzle having its inlet projected within said l chamber to define the opening from said chamber for the accepted fraction, means mounted to ⁇ dene the opening from said chamber for discharging the rejected fraction therefrom, means providing a liquid bath submerging the said chamber and dene an opening therefrom adjacent ⁇ discharge end of the last named means and means on said j -said tangential inlet for discharge of accepted fractions, said nozzle being in spaced relation to the chamber wall, means defining an opening from said chamber at its opposite end for discharge of rejected fractions, said charnber, nozzle and means dening the tangential inlet to said chamber being so arranged that on tangential admission of a liquid suspension a swirling ow thereof is produced adjacent the chamber wall to carry rejected fractions through the opening at said opposite end of said chamber and accepted fractions to and vthrough said nozzle and mems on said nozzle adjacent the inlet thereto in said chamber providing an ⁇ external lateral projection to inhibit -fiow of dirt rich fractions through said nozzle under 4the influence of
