Definitions

  • paper pulp can be homogenized by dispersing and thereby significantly improved.
  • a pulp which has a dry content of between 15 and 35% and has been brought to a temperature which is far above the ambient temperature. It makes sense to carry out the heating when the pulp already has its consistency required for dispersion.
  • the object of the invention is therefore to enable a uniform and efficient treatment of the pulp with the lowest possible power requirement.
  • the teeth and the elevations each have a flat, pointing to the treatment gap head surface.
  • the teeth and protrusions have an outgoing from the respective annular space reason, which leads via radially extending flanks to the corresponding head surface.
  • the circumferentially measured maximum width of the teeth should increase radially inward to ensure sufficient stability of the teeth.
  • radially extending grooves are understood that extend at least with a directional component perpendicular to the circumferential direction of the treatment tool.
  • Figure 2 a partial cross section through a treatment tool 3.4 in the radial direction 9;
  • annular spaces which are arranged so that at least one row of teeth 5 of a treatment tool 3,4 extends into an annular gap of the other, complementary treatment tool 4,3.
  • the elevations 7 in the radially inner region are relatively low, with the respective maximum height of the elevations 7 increasing radially outwards over the tooth base 8.
  • the flow cross-section 13 respectively defined by two adjacent teeth 6 and the intermediate elevation 7 is approximately constant in the radial direction 9 over the entire treatment gap.
  • the width of the elevations 7 in the circumferential direction is approximately equal and is between 1, 5 and 6 mm.
  • the teeth 6 and / or the elevations 7, as shown in Figures 2 and 3 preferably have grooves 15 with a directional component in the radial direction 9.

Abstract

L'invention concerne un dispositif de traitement mécanique d'une matière fibreuse très consistante (1), comprenant un boîtier (2) dans lequel un premier outil de traitement (3) et un second outil de traitement (4) sont disposés de manière à former un interstice de traitement. Les outils de traitement (3,4) présentent respectivement une forme à symétrie de rotation, sont disposés de manière coaxiale l'un par rapport à l'autre, tournent l'un par rapport à l'autre, possèdent des dents (6) disposées respectivement en plusieurs rangées (5) annulaires concentriques par rapport à leur centre, entre lesquelles se situent des espaces interdentaires à travers lesquels la matière fibreuse (1) défile radialement. Au moins une partie des espaces interdentaires possède des surélévations (7) qui s'élèvent au-dessus du fond de dents (8) qui s'étend entre les rangées de dents (5). Des espaces annulaires sont formés entre les rangées de dents (5), et sont disposés de telle sorte qu'au moins une rangée de dents (5) d'un outil de traitement (3, 4) pénètre dans un espace intermédiaire annulaire de l'autre outil de traitement (4, 3) complémentaire. L'invention a pour but de permettre un traitement efficace des fibres avec une puissance requise minimale. Ce but est atteint en ce que la hauteur maximale respective des surélévations (7) au-dessus du fond de dents (8) augmente dans le sens radial vers l'extérieur.
