Definitions

  • the invention relates to a rotor shear for crushing particularly bulky Waste with at least two parallel to each other, counter-rotating, intermeshing cutting rotors, each consisting of several strung together on a shaft, with against Circumferential surface of the opposite shaft or spacer rings and against each other rotor disks provided with working cutting teeth.
  • Such rotor shears are known and are mainly used for crushing waste such as bulky waste, household waste, old tires, bottles or containers made of metal, plastic and the like. Due to the different, often very resistant and tough materials contained in the bulky waste, such as bulky steel parts, steel inserts in old tires, etc., there are great problems with regard to the radial and axial forces to be absorbed and wear, which ultimately have an adverse effect on the shredding process and significantly affect the availability of rotor shears.
  • DE 24 50 936 A discloses teeth on tool rings made of disks, which rather generate axial forces.
  • a scraper device according to GB 2 053 727 A has to be examined, which can lead to an insignificant extent to the reduction of disadvantageous axial forces.
  • a rotor shear consists essentially of two parallel to each other in a housing 1 mounted, driven in opposite directions, meshing Cutting rotors 2, each of which are spaced apart on the shafts 3 lined up, with against the peripheral surface of the between the Cutting rotors 2 arranged on the shafts 3 spacer rings 4 and against each other working cutting teeth 6 (FIG. 2) provided rotor disks 5.
  • the housing 1 has rear walls 1.1, end walls 1.2 and partitions 1.3.
  • the waves 3 are in the end walls 1.2 stored.
  • the on the meshing cutting rotors 2 by means of Spacer rings 4 spaced rotor disks 5 are arranged so that the 1 overhead cutting rotor 2 shown in Fig.
  • FIG. 1 The embodiment shown in FIG. 1 is also conceivable in such a way that only one shaft 3 is assigned two outer wear disks 7, each running against corresponding outer spacer rings 4.1 of the opposite shaft 3 with or without play.
  • the idea of the invention can also be applied to the rotor shears which have several pairs of cutting rotors 2.
  • the wear disk 7 does not abut directly against a rotor disk 5, but is separated from it by a spacer ring 4 or 4.1, the opposite rotor disk 5 then being practically sealed to the partition 1.3.
  • the surfaces of the front tooth flanks 6.1 of the cutting teeth are designed in such a way that geometrically offset and / or angled partial surfaces 6.5 are produced , which lead to a gradual shredding and an optimal effect of the shredding edges 6.2, 6.3 and partial surfaces 6.5 involved in the shredding process.
  • the cutting teeth 6 with the proposed geometries can then be used, which are matched to the material mixture to be shredded.
  • FIG. 2 the geometry of a cutting tooth 6, for example, is shown analogously to FIG. 4b, e and generally transferable to FIGS.
  • the crushing edges 6.2 being the edges lying between the front tooth flank 6.1 and the end faces 6.6 , which work against the shredding edges 6.2 of the cutting tooth 6 of the opposite rotor disk 5 and the shredding edge 6.3 are defined as the edge lying between the tooth head 6.4 and the front tooth flank 6.1, which works against the spacer ring.
  • the angles 6.7 between the partial surfaces 6.5 of the front tooth flank 6.1 and the end faces 6.6 are designated, which in the case of the embodiments according to FIGS. 2, 4a, b, e are approximately or exactly 90 °, a slight drop below such as 89 °, can be advantageous under certain conditions.
  • the rotor disks 5 can advantageously be assembled and reinserted with the end faces 6.6 of the worn crushing edges 6.2, 6.3. It is also possible with composite rotor disks 5 to produce the required thicker versions universally and simply for a corresponding comminution process.
  • each version is designed so that the functions of support and stripping are decoupled, ie that each support / stripping device according to Fig. 3a, b, c with a functionally independent support part 8.1, the spacer ring 4 in a sector 3.1 between the bottom "dead center "and horizontal line of symmetry and with a functionally independent scraper part 8.2 in the region of the lower" dead center "of the spacer ring 4.
  • the support / stripping device 8 according to FIG. 3a, c can be designed as a structural unit, according to FIG. 3a the stripping part 8.2 may be designed as a resilient component and, according to FIG. 3b, it may consist of separate components, such as supporting part 8.1 and stripping part 8.2. As shown in FIG.
  • an additional wiping part 8.3 is provided to avoid material jamming during a reversing operation, which is expediently pivotable. All embodiments have in common that the cutting rotors 2 can be removed from the housing 1 without removing the support / stripping devices 8. Different assignments are possible depending on the material to be shredded. The effect of using the embodiments and arrangements required for the respective comminution process in a replaceable and adaptable manner is typical.
  • Rotor shears are described which optimally match the types of material to be shredded are adjustable.
