Definitions

  • the invention relates to a device for comminuting waste with a housing having a filling opening, in which at least four horizontally intermeshing comminuting rollers are arranged symmetrically to a vertical center plane, each consisting of a plurality of comminuting disks arranged at an axial distance from one another on a drive shaft and offset on the circumference
  • Have fangs which preferably have cutting edges in both directions of rotation, the inner pair of comminution rollers having opposite directions of rotation, and the peripheral speeds increase with increasing distance from the central plane.
  • Such a device with four shredding rollers is already known from DE-OS 2451168.
  • 3,490,706 in which case a knife roller rotating at high speed, which chops and pulverizes the material, is fed with the material by means of a pair of brush rollers on both sides, these also serving to clean the knife roller.
  • the throughput is also limited by the performance of the single knife roller.
  • a comminution device with six rollers is shown in AT-PS 359 812.
  • the upper single coarse comminution roller pair has four intermeshing fine comminution rollers arranged in a square.
  • the invention has now set itself the task of creating a device of the type mentioned, which has an improved shredding performance without increasing the outlay on equipment.
  • the additional shredding effect of the secondary shredding units is achieved by the higher speed of the outer shredding rollers, which also have a clearing effect.
  • the material crushed by the middle pair, but not passing through the sieve bottom, is brought upwards again on the outside, where it is primarily fed to the secondary plants, so that the middle main shredder is mainly used for coarse shredding or remains reserved for it.
  • the secondary shredding units can also perform proportionate coarse shredding work.
  • the increased speed which is made possible by the less effort required for secondary shredding, increases performance.
  • the peripheral speeds of the shredding rollers are approximately doubled with increasing distance from the center plane, and the number of fangs per shredding disk of the shredding rollers adjoining the outside preferably corresponds to the multiplication factor of the peripheral speeds. For example, speeds of 18 to 20 revolutions per minute have proven themselves for the middle shredding roller pair and speeds of 35 to 40 revolutions per minute for each an outer comminution roller, wherein a third comminution roller could be driven at about 60 to 80 revolutions per minute. Due to the low peripheral speed of the inner shredding rollers, only a few fangs are necessary. If, for example, a shredding roller diameter of approximately 28 cm is given, the peripheral speed is approximately 30 cm per second.
  • each inner comminution roller consists of comminution disks, each of which has a fang.
  • each comminution disc of the first comminution roller adjoining the outside has two fangs and each comminution disc of a third comminution roller has four fangs on each side.
  • the diameters of all comminution rollers are preferably of the same size, and each comminution roller has, for example, twelve comminution disks.
  • shredding disks of the inner shredding rollers could also have a double tooth, in particular stepped in height, instead of a single tooth, so that their cutting edges follow one another, for example, at a distance of three to four centimeters.
  • the drive of the shredding rollers is reversible in order to avoid overloading the motor due to jamming or wedging, whereby fangs with cutting edges in both directions of rotation not only lead to the release of wedged material but also to shredding, since each inner shredding roller does not only lead to the second inner one , but also engages in an outer shredding roller.
  • the drives of the shredding rollers are advantageously individually reversible and, if necessary, the speed can also be changed. Especially when reversing the direction of rotation, a further increase in the shredding rate is achieved if the housing on each
  • FIG. 1 shows a vertical section through a first embodiment of a device according to the invention and FIG. 2 shows a partial vertical section through a further embodiment.
  • the device has a housing 1 which is provided with an upper filling opening 2.
  • drive shafts are mounted symmetrically to a vertical center plane 4, each of which is equipped with a shredding roller 5, 6, which is composed of shredding disks 8 provided with fangs 9 and 10, respectively.
  • the shredding disks 8 are arranged axially at a distance from one another which corresponds to the width of a shredding disk 8, wherein they are each offset axially by the disk width and mesh with one another.
  • the two shredding rollers 5 of the inner pair form a main tearing mechanism 14 and rotate in opposite directions, so that the waste filled in via the filling opening 2 is mainly passed between the shredding disks 8 of the rollers 5 and thereby shredded.
  • a grid or screen Floor 13 provided below the inner shredding rollers 5 that has the desired size of the crushed material particles corresponding openings. Since the shredding of the waste, depending on the type of material and the opening width of the sieve plate 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., and above all such material can also wedge or jam between the shredding disks 8, an outer shredding roller 6 is arranged symmetrically to the vertical center plane 4 in a bulge of the housing 1. These take over the material that does not pass through the sieve trays 13 and guide it up again to the side of the filling opening 2.
  • Material from the filling opening 2 is limited by the partially covered arrangement in the bulge of the side wall of the housing 1.
  • the post-shredded material is again guided downwards and falls through the sieve trays 13 with the appropriate size, whereby not yet comminuted particles are conveyed up a second time and fed to the secondary shredder 15.
  • the secondary shredders 15 thereby essentially keep the main shredder 14 free from secondary shredding work, which is thus capable of a significantly increased shredding rate.
  • the outer comminution rollers 6 are also able to loosen material jammed in the inner comminution rollers 5.
  • Each of the two outer crushing rollers 6 shown in the drawings could have a further outside subsequent shredding roller can be assigned, which creates two additional secondary ripening plants.
  • the inner shredding units 6 have a low peripheral speed, which is preferably around 30 cm / sec.
  • the low peripheral speed enables the introduction of high tearing forces with the help of massive fangs 9, 10. Since these are circumferentially offset on the shredding roller 5, for example arranged in a helical manner or also randomly distributed, one serrated tooth 9, 10 can suffice for each shredding disk 8, which can optionally also be formed by a double tooth stepped in height.
  • each ripper tooth 9 has cutting edges 11 on one side, so that its ripping action occurs only in the normal direction of rotation shown by arrows.
  • the outer comminution rollers 6, which have to exert lower forces for the secondary comminution in the two secondary shredding units 15, are driven at higher, preferably approximately twice the peripheral speeds.
  • the lower force load allows an increase in the number of fangs 9, 10, which is preferably approximately proportional to the increased peripheral speed. In the exemplary embodiment, therefore, two fangs 9, 10 are provided per outer comminution disk 6.
  • the higher peripheral speed and the increased number of fang teeth produce a tearing effect in the secondary tearing unit 15 even if the direction of rotation of the inner comminution rollers 5 is reversed for the release of wedged material in the event of a possible overloading of the main tearing unit 14.
  • FIG. 2 which is otherwise of the same design, only shows modified fangs 10 on all comminution rollers 5, 6, which further increases the comminution performance.
  • the fangs 10 are effective there on both sides and are provided with cutting edges 11, so that commutation work is carried out in each of the three tearing mechanisms 14, 15 in any case even when the direction of rotation of each comminution roller 5,6 is reversed.
  • the direction of rotation of one or all of the comminution rollers 5, 6 can be reversed not only in the event of material becoming jammed, but more often over more than one revolution for better attack on the material.
  • the four comminution rollers 5, 6 are provided in a concave arrangement on the filling opening side, i.e. the outer crushing rollers 6 are slightly higher.
  • An axial plane through an outer and inner comminution roller 6, 5 can rise in the shown angle ⁇ of preferably 20 to the horizontal.
