Definitions

  • the invention relates to a device for shredding residual and waste wood, bark, plastics, cardboard or the like.
  • a drivable cylindrical rotor the outer surface of which is equipped with cutting bodies, each of which is fastened in a groove assigned to only one cutting body, these grooves lie in mutually parallel planes perpendicular to the rotor axis, between the grooves, the circumferential surface of the rotor is smooth in the circumferential direction, and a fixed counter blade engages like a comb between the rotating cutting bodies.
  • Such an embodiment corresponding to the first part of claim 1, can be found in DE-A-29 43 567. It is a shredding roller comminution machine with a serration roller, the individual serration teeth, each with a cylindrical or conical shaft, are inserted into correspondingly adapted radial bores in the roller body and are immersed in grooves which are approximately rectangular in cross section and which prevent rotation.
  • the fangs mesh with one or more rows of fixed fangs.
  • Each fang is with a flat rectangular hard metal cutting edge in front view equipped, which is completely radially outside the groove assigned to the fang and in its elongated extent approximately parallel to the rotor axis. The distance between the counter cutting edges and the outer surface of the rotor is so large that the flight circle of basic cutting edges arranged in addition to the fangs in the furrow roller is still outside the counter cutting edges.
  • DE-A-27 02 177 discloses a roller comminution machine with at least one counter-rotating pair of rollers, the rollers of which are equipped with fangs, which are arranged in a helical line.
  • the crushing process is carried out by tearing, specifically because of the differential speed of the intermeshing fangs.
  • a device for shredding residual and waste wood, bark, plastics, cardboard or the like has also become known from prior public use with a drivable cylindrical rotor, the outer surface of which is equipped with cutting bodies which are fastened in cross-sectionally V-shaped grooves .
  • Devices of this type are used for the production of granules which are fed to incineration, landfill or recycling.
  • the grooves mentioned are screwed into the outer surface of the rotor in a spiral and thus lead to jamming during the comminution process by comminution material which is clamped between the rotor and the shear bar.
  • DE-A-23 32 060 discloses a pre-shredder for leadframe waste.
  • the device comprises a roller which is equipped on its outer surface with staggered triangular knives, which sit in axially extending grooves and are fastened to a knife support.
  • Helical guide surfaces run over the axial length of the roller and have their radially lowest in the area of the knives and their greatest radial height between the knives as seen in the axial direction.
  • US-A-3 202 369 discloses an apparatus for tearing sheet metal.
  • cutting bodies On the outer surface of a rotor, cutting bodies are arranged, which are fastened to the end face of a holder above said outer surface and have the shape of an equilateral triangle.
  • the invention has for its object to improve the performance of the device described above.
  • a jamming of the crushing material between the rotor and the shear bar can already be largely prevented by the smooth surface design of the rotor jacket surface between the grooves; however, according to the invention, these jams can be reduced to a minimum by the counter knife projecting close to the outer surface of the rotor.
  • This advantageous effect can be further increased if the shear bar forms an angle of ⁇ 90 ° with the leading lateral surface of the rotor. Due to this arrangement, the self-retracting effect is significantly reduced.
  • each cutting body In order to keep the cutting force as low as possible, the effective section of each cutting body is approximately triangular in shape in the direction of rotation. In order to be able to use the cutting body four times, it is square and rotatable by 90 °.
  • the V-shaped groove has an opening angle ( ⁇ ) of 90 ° and that each cutting body is supported on the two groove flanks in its assembled position.
  • the rotor at both of its axial ends lying outside the working area of the cutting body is equipped with at least one clearing body, the flight circle of which is somewhat smaller than that the cutting body.
  • the rotor can preferably be designed as a solid shaft rotor. It is basically sufficient to arrange the cutting bodies in a single helical line on the surface of the rotor. In order to increase the performance and to gradate the granulate size, several cutting element screw lines can also be provided.
  • the cutting bodies lying side by side in the axial direction can be arranged with an overcut.
  • the distance between the shear bar and the rotor jacket must be adjusted to this overlap.
  • the measures recommended according to the invention reduce the peak loads, the power consumption and downtimes due to material jams and improve the cutting behavior.
  • At least two cutting-body helix lines are provided on the outer surface of the rotor, which are offset by 180 ° with respect to one another, in each case only about half the rotor circumference and in each case only over about half Extend rotor length and each give the shredded material an opposite twist axially to the center of the rotor.
  • This further development of a device results in a concentration of the comminution material in the direction of the central section of the rotor.
  • This has the advantage that the shredding material is not compacted on one side between the rotor, which is designed in particular as a solid shaft rotor, and the shear bar or a switched-on sieve.
  • the device shown only schematically in FIG. 1 comprises a rotor 1 designed as a solid shaft rotor, which is mounted in a fixed position in a machine stand 2 and to which the material to be shredded is fed via a horizontally displaceable hopper 3, the rear wall of which is the material to be shredded against the rotor 1 presses.
  • the rotor 1 is associated with a fixedly arranged and comb-like shear bar 4, which is shown in FIGS. 2 and 3 on an enlarged scale.
  • This shear bar 4 is arranged as close as possible to the rotor 1, so that only a narrow air gap a remains between the shear bar 4 and the outer surface of the rotor 1 (see FIG. 3).
  • the bed knife 4 forms an angle ⁇ ⁇ 90 ° with the leading lateral surface of the rotor 1 (see FIG. 2).
  • the outer surface of the drivable rotor 1 is equipped with cutting bodies 5 which are each arranged in the form of a helix 12 according to FIG. 3.
  • Each cutting body 5 is fastened in a groove 9 assigned only to it, which is V-shaped and as a secant is formed and has an opening angle ⁇ of 90 ° (see Figure 4).
  • each cutting body 5 is designed as a square cutting plate, which is supported in the assembled position with its lower half on the two flanks of the groove 9 and, with its upper, triangular half, forms the section that is effective for comminution.
  • FIG. 4 shows that the cutting bodies 5 lying next to one another in the axial direction are arranged with an overcut.
  • grooves 9 lie in mutually parallel planes which are perpendicular to the rotor axis 10, and that the circumferential surface of the rotor 1 between these grooves 9 has a smooth surface as seen in the circumferential direction.
  • the counter cutting edge 4 engages like a comb between the rotating cutting bodies 5 (see FIG. 3).
  • each cutting body 5 lies against a cutting body carrier 6 and is screwed to the latter by means of a screw 7 shown as an Allen screw (see FIG. 5).
  • the cutting body carrier 6 is welded to the rotor 1.
  • FIGS. 4 and 5 in particular show that each cutting body 5 can be rotated by 90 ° about its central turning axis 11 after it has been removed or before it is installed, and can therefore be used four times.
  • the rotor 1 is equipped at both of its axial ends lying outside the working area of the cutting body 5 with a broaching body 8, the flight circle of which is somewhat smaller than that of the cutting body 5, and the shape of which corresponds to that of the cutting body 5.
  • These clearing bodies 8 clear the inner area next to the side walls of the funnel 3 and thereby prevent material jamming in this area.
