Definitions

  • the invention relates to a device for crushing material, with a Comminution rotor, the carrier disks arranged on a drive shaft in a rotationally fixed manner has, with pointed cutting teeth that in the circumferential recesses of the Carrier disks are arranged and the carrier disks axially the same on both sides protrude, axially adjacent cutting teeth are offset in the circumferential direction, and with a fixed, extending parallel to the drive shaft Counter knife on which a serrated counter cutting edge is formed.
  • Shredding rotors interacting with counter knives for any materials are usually designed as crushing rollers, in which at the Circumferential surface of a cylinder cutting teeth are arranged, the cutting tracks interlock so that the material to be shredded is processed over the entire surface.
  • the cutting teeth are formed by square indexable inserts, so is the roller circumference with V-shaped pockets or grooves in which the square cutting teeth with a raised tip are interchangeably fixed on holders are (DE 39 08 395 A, DE 39 32 345 A, EP 908 238 A).
  • a major disadvantage can be seen in the fact that for each length a separate cylinder manufactured and processed on the scope.
  • the invention has now set itself the task, even in a disc-shaped Interlocking cutting tracks to the device mounted on the knife carrier achieve, and this is achieved by the fact that the center distance of two successive carrier disks smaller than the axial extent of one Cutting tooth is.
  • the cutting teeth per se are arranged parallel to the drive shaft extending holders, each holder in Circumferential recesses of at least two carrier disks is used.
  • the holder provide a stable, torsion-free connection of two, preferred six carrier disks and form massive supports when the cutting teeth pass through square indexable inserts are formed.
  • the stability of the rotor can be further increased if two different ones Recesses are formed on the carrier disks, with a space for the holder and a cutting tooth fixed to the holder and one in the direction of rotation the cutting tooth and free space lying after the holder, the second however only corresponds to the cross section of the holder that fills the recess. Adjacent carrier disks can now be rotated so that the alternate different circumferential recesses in the axial direction.
  • the parts of the protruding axially beyond the carrier disks Rest cutting teeth on support jaws can on the Carrier disc, on the adjacent carrier disc or preferably Covers of the space between the carrier disks can be arranged.
  • the covers are beneficial to keep material from penetrating too deep between the Avoid carrier disks, preferably through each space arcuate cover pieces is covered, on each of which circumferential recesses are intended for two holders.
  • a device for shredding material in particular waste material of all kinds has a housing, not shown, with a filling space, a driven Comminution rotor 1, at least one counter knife 20, 22 fixed to the housing and mostly also feeding devices for feeding and pressing the material onto the Comminution rotor 1, the drive shaft 2 is arranged horizontally.
  • Fig. 1 shows twice six carrier disks, the two Six units are offset by 30 °.
  • Every six unit is out alternatingly rotated by 60 ° carrier discs 3 so that the Cutting teeth 12 of the first, third and fifth carrier disk 3 on the one hand and the Cutting teeth of the second, fourth and sixth carrier disks, on the other hand, each in axially parallel lines are aligned on the circumference.
  • the offset of the second Six unit by 30 ° is possible, for example, that in the Carrier washers this unit the six-sided opening for the drive shaft by 30 ° is twisted.
  • the same carrier disks 3 for both six units can be used be when the drive shaft 2 has a twelve-sided cross section. To this Way, crushing rotors 1 with different lengths few identical parts can be built. Furthermore arise significant simplifications for rotors with large diameters.
  • the center distance of the carrier disks 3, as can be seen from FIG. 4, is designated by m and preferably greater than their thickness, so that between the carrier disks 3 Spaces 5 remain.
  • the carrier disks 3 are with one of the number of cutting teeth 12 extending Number of flattened circumferential recesses 8 and more groove-shaped circumferential recesses 9, each with the Flattened circumferential recesses 8 are formed. Because of the Angular misalignment of the carrier disks 3 thus extend Circumferential recesses 8 and 9 each alternate in axially parallel lines and each take up a holder 11, to which in each flattened recess 8 the cutting teeth 12 is fixed interchangeably by means of a screw connection 14, 15.
  • the Holder 11 has a comb-like shape, as can be seen from Fig.
  • a holder 11 preferably has three triangles standing and three flattened areas, so that it is over six Carrier disks 3 extends and carries three cutting teeth 12.
  • the axial extension z each cutting tooth 12 is larger than the center distance m, so that the Cutting tracks overlap each other.
  • the carrier disks 3 are provided with at least three holes into which the Intermediate space 5 between the carrier disks 3 sleeve or bolt-like spacers 4 are used, which are preferably pluggable Have end areas.
  • arcuate cover pieces 6 are provided which support jaws 13 for the axially projecting regions of the cutting teeth 12 are trained.
  • Each carrier disk 3 and the two to the carrier disk 3 adjacent cover pieces 6 thus form in the area of each Cutting tooth 12 is a V-shaped, massive support for the cutting tooth 12 by the screw sleeve 14 arranged in the cutting tooth 12 and the one through the holder 11 guided screw 15 is fixed.
  • the arcuate cover pieces 6 are supported two spacers 4 each, as can be seen from FIG. 3.
  • the peripheral contour of the Cover pieces 6 are adapted to both adjacent carrier disks 3 which the cutting teeth 12 are arranged angularly offset.
  • Each cover 6 therefore has a central area that is contoured to one with a flattened portion provided circumferential recesses 8 is adapted, and an end region on both sides which also flatten each other Complete circumferential recess 8.
  • a cover ring 16 is arranged at each end of the comminution rotor 1 Support jaws 13 'for the parts of the protruding from the last carrier disk 3 Has cutting teeth 12.
  • the two counter knives 20, 22 are zigzag Provide counter cutting edges 21 whose tooth spacing is smaller than the axial length of the Cutting teeth 12 is because their cutting tracks, as mentioned, overlap.
