Definitions

  • the present invention concerns a means for defibrating and sorting pulp in paper and cellulose industry, comprising a defibrating means consisting of a rotor and a stator, wherebetween is established a defibrating zone, and a sorter consisting of another rotor and another stator, and the stator of said sorter having been formed to be sieve-like, and said means comprising a pulp feed, removal of accept and removal of reject.
  • Apparatus in present use are usually separate defibrators and sorters. Also such apparatus exists which both defibrates and sorts simultaneously.
  • the object of the present invention is to provide a means similar to that described above for defibrating and sorting pulp in paper and cellulose industry, but which is not true of current problems.
  • the means of the invention is characterized in that the rotors of the defibrating means and the sorter only are connected to one another by means of a common shaft and the stators are separate, and said stators and rotors are located in the same pulp space.
  • the defibrating efficiency can be steplessly regulated.
  • the fibre flocs can be dispersed, whereby only particles which are not fit to be included in the accept pump are removed.
  • the defibrating stage or the sorting stage may, if desired, be cut out from the means.
  • the speed of rotation range is properly chosen, the fluidizing effect of the defibrator enables efficient sorting in the same consistency range.
  • stator of the defibrating means by reference numeral 1 and the rotor of the defibrating means by reference numeral 2, said rotor being rotating, as its name indicates.
  • Pulp feed to the space between the stator and rotor blades of the defibrating means is carried out through a connector 6.
  • the pump In the space between the blades the pump is defibrated and proceeds onwards into the sorter rotor 3 established in the same pulp space 5.
  • the rotor 2 of the defibrating means and the rotor 3 of the sorter have a rotating shaft 9 in common.
  • the sorter rotor 3 throws the fibres of appropriate size through the stator 4 of the sorter, formed to be sieve-like, said fibres existing through an accept connector 7.
  • the particles which do not pass the sieve 4 exit through the reject connector 8, as it is customary in sorters.
  • the mode of operation of the means need not be like that described in the foregoing, but the means may operate in that the feed is carried out through a reject connector 8, whereby a sorting process takes first place, and thereafter, the reject is defibrated.
