Definitions

  • the invention relates to a shredding device, in particular for waste material, with a drive and with a housing having an upper filling opening, in the lower part of which a pair of oppositely rotating, intermeshing shredding rollers is arranged, each of which has a plurality of gear-like shredding disks which are axially spaced apart by spacer disks and whose teeth form circumferential cutting elements.
  • Such a shredding device with four shredding rollers arranged in a square, is known, for example, from AT-B 359 812, the gear-like shredding disks of each roller engage in the gaps formed by the spacers of two other rollers.
  • Each shredding roller is arranged on a shaft that is connected to a common drive motor outside the work area via a gear. Since there are strongly fluctuating loads, the gears must be solid.
  • EP-A 142 162 an apparatus for breaking and / or stripping core material is known, an embodiment having disc pairs which are in alignment with one another and mesh with one another in a gear-like manner and which are combined to form two rollers, at least one of which can be driven.
  • the invention has now set itself the task of designing such a shredding device so that both Comminution rollers can be driven by a drive motor without an intermediate gear and can be kept free from material jamming between the comminution disks in a simple manner.
  • shredding disks of the two shredding rollers are aligned with one another, that the shredding disks of the second shredding roller are arranged on a driveless shaft and are driven by their engagement in the driven shredding disk, and in that the aligned gaps between the shredding disks are deflected, Guide or clearing elements are arranged.
  • the shredding disks of the two shredding rollers are aligned with one another, that the shredding disks of the second shredding roller are arranged on a driveless shaft and are driven by their engagement in the driven shredding disk, and in that the aligned gaps between the shredding disks are deflected, Guide or clearing elements are arranged.
  • An additional advantage is that there is no need for a positive connection in the circumferential direction between the non-driven shaft and the comminution disks arranged thereon.
  • the height of the teeth is greater than their depth of engagement. Due to the difference between tooth height and engagement depth, there is sufficient space for the shredded material in each tooth gap despite the engaging tooth of the other shredding disk.
  • the shredding rollers can have different diameters, the smaller shredding roller being provided with the drive. This not only achieves different circumferential speeds that favor the size reduction of the two size reduction rollers, but also a power-saving translation takes place, which makes it possible to use a drive motor with a smaller dimension.
  • a further embodiment provides that broaching elements engaging in the spaces between the two shredding rollers are formed by toothed disks of a driven third roller arranged below the two shredding rollers. In this way, it is impossible to pass through the spaces between the comminuting disks, since this passing, non-comminuted or only partially comminuted material is inevitably gripped and comminuted by the toothed disks of the third roller. Due to the engagement of the toothed disks in the aligned gaps between the two shredding rollers, no material can penetrate into the shredding disks which come out of engagement on the underside, so that the third roller serves on the one hand as a third shredding roller and on the other hand as a clearing roller. The direction of rotation is irrelevant, since it is in any case in the same direction to one and in the opposite direction to the second shredding roller.
  • Comminution devices with three comminution rollers are known per se, for example from DE-A 32 34 485 or DE-A 26 00 454. However, since in both comminution devices the comminution disks of the two top comminution rollers are set to a gap, the third roller underneath only engages one of the two shredding rollers (DE-A 32 34 485), or neither of the two shredding rollers (DE-A 26 00 454). Post-shredding is thus incomplete and the clearing is more fixed Material parts can be made from at most one shredding roller.
  • the toothed disks of the third roller can have teeth which are delimited by approximately V-shaped, rounded cutouts.
  • the toothed disks of the third roller thus resemble sprocket gears, and this shape has proven to be particularly favorable for the secondary comminution and the removal.
  • the speed of the third roller is of no particular importance, but it has proven to be advantageous if the speed of the third roller is greater.
  • the third roller is arranged in the vertical central plane between the two shredding rollers, and the toothed disks of the third roller are approximated to spacer disks between the shredding disks of both shredding rollers are. Since this version is completely symmetrical, only the same deflector elements can be used. It has proven to be advantageous here if the axes of the three rollers are determined approximately by the corner points of an equilateral triangle.
  • deflection or guide elements are arranged fixed to the housing and support the spacers. This prevents the material from being returned outside the shredding rollers to the side of the inlet opening. It is particularly expedient if deflecting elements engaging in the spaces between the two shredding rollers are provided on the side of the filling opening.
  • the deflector points to the side the filling opening preferably has a cutting edge which projects beyond the teeth of the comminution disk adjacent on both sides.
  • the squeezing of in particular long-fiber material between the toothed disks of the third roller and the spacers of the counter-rotating shredding roller can also be prevented in a preferred embodiment if the third roller is arranged at a distance from a vertical central plane between the two shredding rollers and the toothed disks of the third Roller on the one hand are approximated to the spacer disks between the shredding disks of the shredding roller rotating in the same direction and on the other hand to the deflecting elements between the shredding disks of the shredding roller rotating in opposite directions.
  • each deflecting element has a cutting edge directed towards the third roller between the shredding disks of the shredding roller rotating in opposite directions.
  • a shredding device is used in particular for shredding not too bulky, in particular compostable, waste of all kinds, such as paper, cardboard, wood, garden waste, etc. and has a housing 1 in which two intermeshing, horizontally running shredding rollers 2, 3 are arranged side by side.
  • Each shredding roller 2, 3 comprises a shaft 4, 5 mounted in the side walls of the housing 1, on which, with the interposition of spacer disks 13, aligned pairs of shredding disks 6 are arranged at an axial distance from one another.
  • Each shredding disk 6 is provided on the circumference with uniform cutting elements in the form of teeth 7, so that it is designed like a gear.
  • the thickness of each comminution disc 6 is preferably greater than the width of the respective space 18 given by the spacer discs 13.
  • the teeth 7 of two comminution discs 6 engage in one another, the depth h of the tooth spaces 8 being greater than the engagement depth a. This forms a receiving space for the material crushed between the teeth 7, which is further enlarged by a tapering of the tooth base 10.
  • a comminution roller 3 is thus driven by the other comminution roller 2, which is associated with a drive 17, not shown in detail.
  • the shaft 4 has a quadrangular or hexagonal cross section, as a result of which the comminuting disks 6 threaded thereon are held in a form-fitting manner in the circumferential direction, while the shaft 5 of the second comminuting roller 3 has a round cross section.
  • the shaft 4 is custom-made, and the shredding discs 6 and the spacers 13 of the shaft 5 are easier to manufacture due to the cylindrical center bore.
  • the teeth 7 of the comminution disks 6 can be arranged with a circumferential offset in the longitudinal direction, as a result of which the rows of teeth lie approximately in a helix, which may favor the comminution.
  • each side wall carries a squeegee 26, in order to prevent the penetration of material in the event of a brief, temporary reversal of the direction of rotation of the shredding rollers 2, 3, which is indicated by arrows.
  • a third, driven roller 21 is provided below the two shredding rollers 2, 3, which is likewise composed of spacer disks 25 and toothed disks 22 and the direction of rotation of which is arbitrary.
  • Approximately V-shaped, rounded cutouts 24 are provided between the teeth 23 of the toothed disk 22.
  • the toothed disks 22 are each aligned with two mutually opposite spacer disks 13 of the two comminution rollers 2, 3 and with the deflecting elements 14 supporting them, and thus engage in the spaces 18 between both comminution rollers 2, 3. Material crushed from the teeth 7 of the crushing disks 6 falls down and is transferred into an outlet 12 via the spacer disk 25 of the third roller 21 underneath.
  • the third roller 21 can also be arranged symmetrically, that is to say in the central plane between the two comminution rollers 2, 3, the teeth 23 then being approximated to the spacer disks 13 of both comminution rollers 2, 3.
  • deflecting or guiding elements 14 are shown, which partially bridge the feed gap on the side of the filling opening 11 and each extend into the opposing shredding roller 2, 3. These deflecting elements end in a cutting edge 20 which protrude radially beyond the teeth 7 of the comminution disks 6. The feed gap for the material to be shredded is thereby also reduced in the spaces between the shredding disks 6 and the shredding effect is also improved by the additional cutting edge 20.
  • the deflecting elements 14 carrying the cutting edge 20 alternately enclose every second spacer 13 on the shafts 4, 5 so that they appear combing into one another.
  • a deflector element 14, similar to FIG. 1, is provided on the opposite side, which supports the spacers 13 from below.
  • the roller 21 shown in FIGS. 1 and 2 is also preferably provided in this embodiment, but is not shown for reasons of clarity. Likewise in the embodiment according to FIGS. 1 and 2, the arrangement of deflecting and guiding elements 14 according to FIGS. 3 to 7 is possible, which are led to the side of the filling opening 11.
  • the height h of the teeth 7 is preferably greater than twice the engagement depth a, so that there is a large receiving space at the bottom of each tooth gap 8 for material entering the toothing is achieved.
  • open side recesses 9 facilitate the material exit, so that the bottom of each tooth gap 8 is designed like a cutting edge.
  • the shredded material falls down through the outlet 12.
  • the outlet 12 can lead like a funnel to a channel-shaped support in which a screw conveyor is arranged. This can be continued in a machine part arranged outside the comminution device as a press screw for pressing the comminuted material.
  • the funnel-like feed is limited by deflecting or guiding elements 14, which are fixed lying on the support and each protrude into an intermediate space 18 between two comminution disks 6 as far as the respective spacer disk 13.
