Definitions

  • the invention relates to a rotor shear for crushing waste, in particular of metallic and non-metallic waste material, with two oppositely driven, intermeshing rotors made of rotor disks provided with cutting edges.
  • a rotor shear of this type has become known from DE-OS 30 33 752. Waste such as bulky waste, household waste, old tires, bottles or containers, e.g. Barrels made of metal, plastic or the like. crushed. Due to the shape of the rotors, they exert a kind of collecting or pocket effect on the bulky material fed through a hopper, which causes most materials to be drawn in without the aid of a pressure element (tamper).
  • the invention has for its object to improve the operation of a rotor shear, in particular to make it more variable with regard to the size reduction result.
  • the rotors have at least one coarse and one fine grinding area. To carry out both a coarse and a fine comminution, all that is required is a single rotor shear with two rotors and at least one drive, which then also drives the second rotor via an intermediate gear.
  • the two rotors are assigned to each other in the scissor housing in such a way that the two coarse and fine comminution areas interact.
  • Each rotor consists of coarsely shredding, wider rotor disks and fine shredding, narrower rotor disks.
  • the rotors are consequently divided into two lengths with different rotor disc configurations; where the rotors are wide Own rotor disks, the coarse shredding area is located on a partial length of the rotors.
  • the materials to be comminuted can be fed to the desired comminution stage in a targeted manner and without interfering with one another or mixing with one another.
  • the coarsely comminuting rotor disks are approximately twice as wide as the finely comminuting rotor disks arranged on the remaining length of the rotors.
  • the rotor disks can be adapted to any requirement profile for the degree of coarse or fine comminution.
  • the finely comminuting rotor disks have a larger number of cutting teeth than the coarsely comminuting rotor disks, the finer tooth pitch results in an even finer degree of comminution than is already achieved due to the different widths of the rotor disks.
  • the coarse shredding area of the rotors can advantageously be made larger than the fine shredding area.
  • Each rotor thus consists of coarsely comminuting rotor disks over more than half of its length, the partial lengths of the coarse and fine comminution areas preferably being in the ratio of about 3: 2.
  • a discharge conveyor assigned to the coarse shredding area is connected to an ascending conveyor which ends above the filling trough and is assigned to the fine shredding area.
  • the coarse or pre-shredded material reaches the fine shredder, for example, via a discharge conveyor starting from the outlet of the coarse shredding area and a subsequent inclined slide on the ascending conveyor. Since the discharge conveyor delivers the coarsely shredded material to the ascending conveyor in the material flow, the fine shredding area can be continuously supplied with pre-shredded material.
  • the material is then finally removed from the comminution process, for example by a further conveyor, which may also be fed via an inclined chute, and is carried away under the scissor outlet in the section of the fine comminution area.
  • the rotor shear according to the invention can optionally also be operated in such a way that only coarse or fine comminution is carried out; in this case, only the corresponding shredding area of the rotors is supplied with material.
  • the ascending conveyor to the fine shredder can advantageously be preceded by a sieving stage, alternatively or additionally a suction stage and / or a magnetic separator. If the material following the coarse shredding is first passed, for example, through a sieve drum with a combined suction, dirt and materials which have already been chopped up sufficiently, as well as hard materials, can be removed Remove iron parts from the material flow before the coarsely shredded material is thrown into the fine shredding area of the rotary shears. The fine crushing process is thus relieved of dirt and already sufficiently crushed material; The comparatively more sensitive tools are protected from damage by removing the iron parts beforehand.
  • the rotor shear 1 consists of a housing 2, which is supported on the foundation 4 via legs 3, and a filling trough 5 which opens into the housing 2 from above.
  • a pre-compressor 6 which can be pivoted into the filling trough 5 from the side is connected to the scissor frame by means of at least one acted upon movably mounted adjusting cylinder 7.
  • its end wall 8 facing the filling trough forms a surface which is flush with the filling trough wall 9.
  • the end wall 8 cf. number 8'
  • the end wall 8 actively acts on the material, not shown, fed via the filling trough 5, in order to prevent the material being drawn in between two stored in the housing 2 Support rotors 11, 12.
  • the rotors 11, 12 each provided with their own drive 13, 14 (cf. FIG. 3) are driven in opposite directions in such a way that both rotate downward in the overlap region.
  • the rotors 11, 12 each consist of rotor disks 19, 21 arranged on a shaft 15, 16 and provided with cutting teeth 17, 18 (cf. FIGS. 1 and 2).
  • FIG. 3 in the detail of FIG Rotor 12 is shown, the rotors 11 and 12 are equipped with rotor disks 19 on a partial length 22 that is more than half the total length of the rotors and rotor disks 21 on the remaining length 23.
  • the rotor disks 19 are on the one hand wider and on the other hand have fewer teeth 17 than the rotor disks 21 which, due to their smaller width and larger number of teeth 18 (see FIGS. 1 and 2), divide material fed via the filling trough 5 much more finely than that Rotor disks 19.
  • the wide rotor disks 19 arranged on the partial length 22 thus form a coarse shredding area 24, and the narrow rotor disks 21 arranged on the remaining length 23 of the rotors 11, 12 form a fine shredding area 25 of the rotor shears 1, in which the mostly strip-shaped material from the coarse shredding area transversely is divided.
  • Above the rotors 11, 12 extends in the transition from the coarse to the fine comminution area 24, 25 a dividing wall 26 dividing the filling trough 5 according to its different comminution areas (cf. Fig. 3); it ensures that the materials of different sizes supplied to the separate work areas via the filling trough 5 do not mix.
  • An inclined chute 28 arranged under the housing 2 at the scissor outlet 27 directs the material pre-comminuted in the coarse comminution area 24 by the rotor disks 19 with its teeth 17 to a discharge conveyor 31 surrounded by a belt box 29 in the ejecting area of the inclined chute 28.
  • the conveyor 31 throws the material transported from the coarse shredding area 24 at its head end 33 into an inclined chute 34, which forwards the material to an ascending conveyor 36 protected in the takeover area by a belt box 35.
  • Both the removal conveyor 31 arranged below the rotor shears 1 and the ascending conveyor 36 are supported on the foundation 4 by means of posts 37.
  • the head end 38 of the ascending conveyor 36 ends above the feed section of the filling trough 5 assigned to the fine comminution area 25 of the rotors 11, 12, so that the coarsely pre-comminuted, often strip-shaped material 32 reaches the rotor shears 1 again in a continuous pass, but then there in the fine comminution area 25 is crushed.
  • both a coarse and a fine comminution of coarse, bulky piece goods can be achieved in an uninterrupted processing sequence with just one rotor shear. This does not preclude, if desired, either to carry out only a coarse or only a fine comminution of the material fed in, or to simultaneously work separately in a fine and coarse comminution; all that is needed is to allocate and allocate the necessary funding.
