Definitions

  • the present invention relates to a comminution machine, in particular for cutting fibrous material, especially for chopping wood.
  • Conventional shredding machines have a screw conveyor for the removal of the chips, which is arranged essentially parallel to the rotor axis and transports the chips that occur during the shredding process.
  • a suction device which may be arranged behind the screw, transports the wood chips from the screw to an ejection chute. This arrangement has the disadvantage that the screw conveyor complicates and increases the cost of the arrangement.
  • the object of the present invention is to provide a comminution machine which is suitable for working without a screw conveyor.
  • a comminution machine is specified with a rotor chamber, a conveyor belt introduced into the rotor chamber for removing material to be comminuted and a chopping rotor rotatably arranged in the rotor chamber, which is characterized in that a suction fan is provided radially outside the rotor, the axis of which is essentially transverse is arranged to the rotor axis.
  • the shredding machine according to the invention is characterized by a suction device in the form of a suction fan, which is arranged radially outside the rotor in such a way that it picks up and transports the wood chips generated by the rotor directly behind the rotor.
  • the arrangement of a screw conveyor is omitted.
  • the fan is preferably arranged on a side of the rotor opposite the conveyor belt with respect to the rotor. With this arrangement, that will Goods to be shredded transported on the conveyor belt are gripped by the rotor and transported tangentially into an area of the rotor space opposite the conveyor belt, from where it is transported away under the suction effect of the fan.
  • the blower axis In the operating position of the shredding machine, the blower axis is located lower than the rotor axis. This takes account of the fact that the location of the comminution is in the region of the lower periphery of the chopping rotor, the chips, due to gravity, describing a downward tangential path from the rotor periphery.
  • the suction fan which is located below the rotor axis, easily takes up these wood chips.
  • a separating screen is arranged between the rotor and the fan.
  • a separating sieve has a mesh size set in such a way that only wood chips with a dimension below the mesh size pass through and are transported away.
  • the separating screen is adapted to the rotor periphery and therefore has an at least partially circular profile in cross section.
  • the conveyor belt is angled in the area of the rotor space and extended into an area below the rotor.
  • a chopping rotor 4 is rotatably mounted with its rotor axis 1 in a rotor space 2.
  • a conveyor belt 6, 8 is guided in a horizontal direction, which is angled at an obtuse angle in the area of the rotor space 2.
  • a conveyor belt section 6 runs approximately horizontally, while at a bend point, for example a roller, a conveyor belt section 8 begins, which is extended to a region below the rotor 4 or the rotor space 2.
  • a counter conveyor belt 10 which is fixedly mounted on its upper roller, its lower roller being self-supporting, so that the conveyor belt 10 is more or less inclined depending on the size of the material to be conveyed.
  • a separating screen 18 is provided, adapted to the chopping rotor circumference, which delimits the rotor space 2 and is selected in its mesh size such that only sufficiently fine chips with a diameter below the mesh size can leave the rotor space.
  • a suction blower 12 the axis 14 of which is arranged essentially horizontally and perpendicular to the rotor axis 1.
  • the fan axis 14 is located below the rotor axis 1 and is also located lower than the upper run of the conveyor belt section 6.
  • the suction fan 12 has blades 16 which, due to their inclined position, exert a suction effect.
  • the overall diameter of the suction fan 12 is chosen so that the airfoils extend up to the region of the center point of the rotor axis 1.
  • the overall diameter of the blower is also selected so that it covers the entire length of the rotor, so that the blower unfolds a sufficient suction effect in its entire depth to all from the Rotor chips emerging from the rotor chamber.
  • the conveyor belt section 8 which is elongated below the rotor space 2, ensures that chips going downward are taken along by the conveyor belt 8 in the direction of the blower 12.
  • the suction fan is particularly preferably reduced in cross-section at its suction opening (not shown) in order to achieve an increased suction effect.
