Definitions

  • the invention relates to a pre-shredding and dosing device, in particular for large plants for the destruction of files and the like. Waste materials in a basic construction which can be extracted from the preamble of patent claim 1.
  • cutters with a bevel on one side are already known for document shredders, which in one variant abut one another in pairs with their highest circumferential edges and thereby have larger axial distances between the pairs of discs.
  • Such a cutter alone is not suitable for the destruction or pre-shredding of thick bundles of files, just like the shredding device for waste materials known from DE-U-92 00 058.
  • the object of the present invention is therefore above all to eliminate the known disadvantages of devices previously on the market in a convincing and at the same time also save drive energy by a novel design of the pre-shredder cutting unit.
  • FIGS. 1 and 2 which is shown purely schematically in FIGS. 1 and 2, is formed by a waste filler chute "E" with a pre-shredder arranged on the bottom side thereof and made up of cutting disks 3, 4 equipped with cutting rollers 3, 4, with this being a largely vertically directed discharge chute “AL “followed by a largely horizontally directed conveyor belt” F “leading to a secondary shredder” NZ ";
  • the waste material is fed in via the "SF” inclined conveyor.
  • Automatic, load-dependent control of the material feed is important here, especially with reversing operation of secondary shredder "NZ” and conveyor belt “F” if the cutting unit there is overloaded.
  • the connection of the conveyor belt “F” before the secondary shredder “NZ” has an additional homogenizing effect for the dosing.
  • the crushing effect of the new cutting unit is further supported or improved by the resulting from different cutting disc diameters "D 1 and D 2 " for each cutting roller 1 and 2 and at the same time different roller speeds including possibly different heights "H" of the stylus or teeth 3b and 4b , changing feed or engagement conditions on the shredder.
  • the new system is ultimately completed by the "E" infeed shaft from both sides the interstices between the pairs of knife disks up to the cutting roller base 1a and 2a scraper grate bars 5, advantageously at least the free ends 5a of the bars 5 being inclined or chamfered towards the roller base 1a and 2a and thus the waste material always leading to the comminution members.
  • the conveyor belt “F” is independent of the material input by the feeder at any time, the additional loading of the secondary shredder "NZ" with sheet material or the like to be destroyed. possible.

    en ce que les disques de coupe (3, 4) possèdent un dos chanfreiné (3a, 4a) et se trouvent en engagement mutuel en étant respectivement appliqués par paire l'un contre l'autre par les arêtes périphériques les plus hautes (K) des chanfreinages (3a, 4a), et chacune de ces paires de disques (3, 4) est fixée sur les arbres d'entraînement ou encore les cylindres de coupe (1, 2) à une nette distance (a) de la paire immédiatement consécutive de disques (3', 4') dans la direction longitudinale (L) des arbres,
    en ce que les dents (3b, 4b) sont ménagées à la manière de ciselets dans les corps des disques de coupe (3, 3', 4, 4') par détalonnage à la fraise ou analogue en hélice (W) et sont, pour chaque cylindre de coupe (1, 2), fixées sur ces derniers en étant mutuellement décalées selon une forme d'hélice correspondante (W),
    et en ce que les disques de coupe (3, 4) de chaque cylindre de coupe (1, 2) présentent des diamètres différents (D1, D2) et tournent en même temps à des vitesses de rotation différentes.
  2. Dispositif de prébroyage selon la revendication 1, caractérisé par des hauteurs différentes (H) des ciselets ou dents (3b, 4b).
  3. Dispositif de prébroyage selon au moins une des revendications précédentes, caractérisé par des barreaux de grille de raclage (5) qui s'enfoncent par les deux côtés du puits d'alimentation (E) dans les espaces intermédiaires entre les paires de disques de coupe jusqu'au fond (1a, 2a) des cylindres de coupe.
  4. Dispositif de prébroyage selon la revendication 3, caractérisé en ce qu'au moins les extrémités libres (5a) des barreaux (5) s'étendent en inclinaison ou en bas (5b) vers le fond (1a, 2a) du cylindre.
  5. Dispositif de prébroyage selon au moins une des revendications précédentes, caractérisé en ce qu'un puits d'évacuation (AL) orienté essentiellement verticalement, ainsi qu'une bande transporteuse (F) orientée essentiellement horizontalement qui se raccorde au puits (AL) et mène à un broyeur secondaire (NZ), sont disposés à la suite de l'unité de coupe (1 à 4).
