Definitions

  • the invention relates to a comminution device m 5 with intermeshing comminution rollers which have interacting pairs of comminution elements equipped with fangs.
  • Such a shredding device is shown in the OH-IO PS 630 538.
  • the two rollers are provided with disks aligned in pairs, which have cutting rings composed of segments on one end face. Despite the aligned arrangement of the pairs of disks, comminution takes place between the cutting rings 15 axially offset disks. Claws and elevations on the periphery of the disks interlock with one another with great play and serve to capture and convey the material.
  • the comminution device shown in AT-PS 339 705 each has ring segments provided with a ripper tooth, which are screwed together to form an annular body enclosing the drive shaft in a circumferential direction.
  • a similar embodiment is also the case with the comminution device according to GB-PS 2 024 655, US-PS 4,241,882 and US Pat
  • EP-A 420 731 the disks of the rollers are each set to a gap.
  • comminution ring bodies are provided which are spaced apart from one another and each consist of two rings ⁇ attached to the drive shaft and ring segments arranged between them and detachable fangs.
  • the object of the invention is therefore to create a comminution device of the type mentioned at the outset which has an improved comminution effect.
  • each pair of comminution elements is formed by two ring segments, and each ring segment occupies approximately half the circumference of the comminution roller and engages in the circumferential region of the other comminution roller that is free of ring segments.
  • each ring segment is formed by a radially projecting area of a ring which is detachably fixed on the drive shaft.
  • each ring segment is fastened to the drive shaft or to a ring arranged on the drive shaft by means of at least one screw.
  • Each ring segment preferably extends over 175 ° to 179 ° and each free circumferential area extends over 181 ° to 185 °, as a result of which the greatest possible free spaces are formed without changing the size of the comminution.
  • one or more fangs are formed per ⁇ 5 ring segment.
  • each ring segment is approximately the same or slightly larger than half the distance
  • the height of the ring segment and the ripper tooth is equal to or slightly smaller than the distance between the free circumferential areas of the comminution rollers, particularly good comminution results are achieved, since the end edges of the ring segments are first tear tools,
  • the end faces of the ring segments can also run in accordance with the end faces of the fangs and are therefore not flat but, for example, concave.
  • All comminution rollers preferably have the same 25 diameters.
  • the diameters of the comminution rollers can also be different, however, since the necessary same speed is always reached when the circumferential speeds of the comminution rollers behave like their diameters.
  • FIGS. 1 and 2 each show a schematic cross section through two different comminution devices according to the invention, and FIG. enlarged representation of the right pair of rollers of Figure 2 in a rotated position.
  • the comminution device has a housing 1 which is provided with an upper filling opening 2.
  • drive shafts 5 driven at the same speed are mounted symmetrically to a vertical center plane, each of which drives a comminution roller 3, 4.
  • the two shredding rollers 3 of the inner pair form one
  • a grating or sieve plate 13 is provided essentially in parallel, which has openings corresponding to the desired size of the comminuted material particles. Since the shredding of the waste, depending on the type of material and the opening width of the sieve tray 13, initially leads to a larger amount of material particles which do not fall through the sieve openings, in particular when shredding cardboard boxes, plastic waste, etc., is symmetrical the outer pair of crushing rollers 4 are arranged to the vertical center plane.
  • Each of the outer comminution rollers 4 is designed essentially the same as an inner comminution roller 3 and forms with it a secondary shredder 15, which is used primarily for the secondary comminution of the material being conveyed.
  • the post-shredded material is guided downwards again and falls through the sieve tray 13 if the size is appropriate, particles which have not yet been adequately shredded being conveyed up a second time and fed to the secondary shredder 15.
  • Each comminution roller 3, 4 has a number of non-rotatably arranged ring segments 6, each of which extends over almost 180 °, so that a circumferential region 9 which forms a gap remains slightly above 180 °.
  • the ring segments 6 are arranged on each drive shaft 5, in particular in a helically offset manner, from which the initial contour 8 indicated by broken lines in FIG. 3 results.
  • One or two fangs 7 are provided on each ring segment 6, which thereby also extend helically along each comminution roller 3, 4, as the circumferential contour 14 indicated in broken lines in FIGS. 1 and 3 shows.
  • Each ring segment 6 of each comminution roller 3, 4 lies in a common radial plane, so that when the comminution rollers 3, 4 rotate, each ring segment 6 engages in a free circumferential region 9 of each adjacent comminution roller.
  • the height of the ring segments 6 corresponds in each case to approximately half the distance between the free circumferential regions 9, so that the circumferential contours 8 touch or slightly overlap.
  • the ring segments 6 have end edges 18 which serve as first tearing tools, and in order to avoid direct contact of the end edges 18 of two ring segments 6, which could lead to their damage, the ring segments 6 each have a flattening at the end 10 on its peripheral side.
  • the height of the fangs 7 arranged on the ring segments 6 is equal to or slightly less than the height of the ring segments 6.
  • the ring segments 6 are radially protruding areas of rings 16 threaded onto the drive shaft 5 so that they cannot rotate, the drive shafts 5 being hexagonal.
  • the ring segments 6 are fixed by means of hold-down devices 11, which are each inserted into a bore of the ring segment 6 and through which Screw 12 are fixed to the rings 16 or directly to the drive shafts 5.
  • hold-down devices 11 which are each inserted into a bore of the ring segment 6 and through which Screw 12 are fixed to the rings 16 or directly to the drive shafts 5.
  • two such fastenings can be provided per ring segment.
  • the edges of each ring segment, which extend in the circumferential direction, can optionally form cutting edges which are effective at least in the end sections due to the helical displacement.
  • the counter-rotation of the inner comminution rollers 3 results in the engagement of each ring segment 6 in To enable the free peripheral area 9 of the second comminution roller 3, an asymmetrical arrangement of the ring segments 6 offset by 180 ".
  • the ring segments are on the outer comminution rollers 4, which each have the same direction of rotation as the adjacent inner comminution roller 3 6 parallel to those of the inner comminution roller 3.
  • the diameter of the outer shredding rollers 3 is smaller than that of the inner shredding rollers 4, so that they have a higher peripheral speed around the engagement of each ring segment 6 in the free peripheral region 9 of the other shredding rollers to enable.
  • the drive shafts 5 can lie in mutually inclined planes. However, it is also possible to arrange them in a common horizontal plane.

Abstract

Un dispositif de broyage comportant des cylindres de broyage s'engageant les uns dans les autres présente des éléments de broyage formés par des segments annulaires (6) et munis de dents. Les segments annulaires (6) occupent respectivement à peu près la moitié de la circonférence de chaque cylindre de broyage (3, 4) et s'engagent dans les zones de la circonférence (9) des autres cylindres de broyage, laissées libres par les segments annulaires (6). Chaque segment annulaire (6) est constitué de préférence par la zone radialement en saillie d'un anneau (16) fixé de manière amovible sur l'arbre d'entraînement (5).
