Definitions

  • the invention relates to a waste comminution device with a drive, with a housing having a filling opening, and with a rotating comminution roller having circumferential cutting bars, which cooperates with a counter-cutting tool, the material being comminuted during the passage between the cutting tools.
  • Such a shredding device in which the counter-cutting tool is a stationary counter knife, is known for example from DE-U 91 09 063.
  • a clearing spatula is provided which, coupled to the roller drive, engages and clears a gap continuously.
  • Shredding devices in which the counter-cutting tool is also formed by a shredding roller are also already known.
  • the shredding rollers can be formed from shredding disks equipped with fangs, which are lined up on drive shafts at a distance from one another.
  • one-piece shredding rollers can also be used, on which axially spaced cutting elements or teeth are provided. Examples of both versions can be found in AT-B 350 988.
  • waste shredders A problem with all waste shredders is that the waste materials to be shredded have different properties, so that the shredding devices only function more or less satisfactorily. It happens again and again that despite a possible drive reversal and clearing elements engaging in the gaps, the material is poorly crushed and pinched. The device must then be at least partially disassembled for cleaning.
  • FR-A 753.030 describes a kneading mill for poured grain, and FR-A 497.045 a device for crushing crops and in FR-A 2466 281 a device for producing small tomato paste pieces. All three devices contain interlocking strips with sieve drums that must pass through the material, which then emerges at the end faces. A passage between the sieve drums is not possible because the housing under the drums is closed.
  • the object of the invention is therefore to improve the functional reliability of such a shredding device and, in particular, to create additional free spaces for material which is not or only poorly shredded in order to avoid the device being blocked.
  • the comminution roller is hollow and has at least one open end face, and in that open passage slots are formed between the cutting bars in the roller cavity as additional discharge paths for material which is not comminuted or is comminuted poorly. In this way, this material cannot settle between the cutting strips and clog them, but is pressed further into the roller cavity by the subsequent material.
  • the counter-cutting tool is preferably also formed by a comminution roller which rotates in the opposite direction to the first comminution roller and likewise has circumferential cutting bars which engage in the cutting bars of the first comminution roller.
  • the second comminution roller is also hollow and has at least one open end face, open passage slots being formed between the cutting bars in the roller cavity of the second comminution roller.
  • the cutting strips can both run parallel to the axis and at an angle to the axis.
  • the passage slots preferably expand into the roller cavity so that the material cannot become jammed.
  • the material penetrating into the roller cavities emerges through the openings in the end faces due to gravity when the rollers are not in a horizontal position.
  • a clearing element which acts towards the open end face is preferably provided in each roller cavity, so that forced emptying takes place irrespective of the position of the comminution rollers.
  • the material emerging from the roll cavity is, depending on its degree of comminution, either returned to the comminution device for further comminution or added to the material comminuted by the rolls.
  • the clearing element can be arranged fixed to the housing. Such a clearing element protrudes at least on one side from the roller cavity and is outside of the housing, in particular by means of a mounting bracket or the like. attached.
  • the clearing element consists of a plate which is curved and adapted to the roller and which, with or without a distance from the inside of the roller, is axially parallel or inclined and is effectively arranged in one or both directions of rotation in the roller cavity.
  • the plate has a trapezoidal shape extending over approximately one third of the circumference, on the narrow side of which the mounting bracket is provided. The sloping sides of the plate form broaching edges along which the material is discharged due to the rotation of the roller and can also act as cutting edges that penetrate the material penetrating through the spaces Shear off the inside of the roller and use it to shred.
  • a helically coiled web for example a section of a screw conveyor, can also be arranged in the roller cavity as the broaching element.
  • the screw conveyor is preferably also fixed to the housing; however, their drive is also conceivable.
  • the second end face of the shredding roller is closed by a cover. Since the two rollers or their cutting strips engage in a form-fitting manner in the circumferential direction, it is provided in a further preferred embodiment that the drive is assigned to only one comminution roller. In this case, it is also advantageous if the cutting strips of the driven shredding roller are wider than the cutting strips of the second shredding roller.
  • the shredding device has a rectangular housing 1 with four side walls 2.
  • Two shredding rollers 4, 5 are hollow cylindrical and are rotatably supported with their end bearing sections 3 in opposite side walls 2. Between the bearing sections 3, the two shredding rollers 4, 5 are provided with longitudinal webs projecting from each other and projecting over the circumference of the bearing sections 3. These form cutting strips 6; 15, 16 for the waste material to be shredded and have cutting edges.
  • the bearing sections 3 can be formed, for example, by rings grooved on the circumference, into which graduated longitudinal webs are interchangeably inserted at the ends.
  • the cross section of the cutting strips corresponds to that of a fang.
  • the cutting strips 6; 16 of the one roller 4 engage in the spaces between the cutting strips 6; 15 of the second roller 5, so that there is a gear-like engagement between the two shredding rollers 4, 5. It is therefore sufficient to assign only one drive 13 to the roller 5.
  • the spaces between the longitudinal webs are open in the roller cavity 8, that is to say the cutting strips 6; 15, 16 are separated from one another by through-slots 7.
  • Material gripped by the cutting bars is shredded as it passes between the two shredding rollers 4, 5 and falls down. Material that is not or only partially shredded, which could fill the spaces between the longitudinal webs and thus impair the function of the shredding device, is pressed into the roller cavities 8 through the passage slots 7.
  • the passage slots 7 widen inwards for easier passage of the material.
  • a broaching element 9 is arranged fixed to the housing, which in the embodiment according to FIGS. 1 to 3 is designed, for example, as a trapezoidal, curved plate.
  • the plate can be on the inside of the Roller 4,5 lying adjacent or at a distance from it extend parallel or also slightly inclined to the roller axis.
  • the sloping sides of the plate form a cutting edge for each direction of rotation, which can crush or shear material entering through the through slots 7 and at the same time a clearing edge 11, along which the material is conveyed out of the roller cavity 8 to the outside.
  • the plate protrudes from the roll cavity 8 on one side and is fastened to the outside of the housing wall 2 by means of a mounting bracket 10.
  • a cavity cover 12 is provided, which is formed on the driven shredding roller 5 by a drive flange connected to its bearing section 3.
  • the clearing plate 9 can extend over an angle between approximately 60 ° and 300 ° and over any angular range.
  • the arrangement of the broaching plates 9 in the upper region of the rollers 4, 5 prevents the penetration of material not supplied to the cutting mechanism into the roller cavities 8.
  • the clearing element 9 is formed by a stationary screw conveyor 17 which has a plate-shaped mounting bracket 20. This is fastened by means of screws 21 to a further housing wall 18 arranged at a distance from the housing walls 2.
  • the screw conveyor 17 is penetrated by a shaft 14 which is mounted in the housing wall 18 and connected to the cover 12. This provides an additional bearing for the comminution roller 4, 5 and a support for the screw conveyor 17 also in the interior of the roller 4, 5.
  • the rotation of the roller 4,5 the material passing along the screw surface the screw conveyor is conveyed to the outside. There it falls (arrows 19) as well as material crushed between the rollers 4, 5.
  • a partition not shown, can keep the two material parts separate from one another, so that the material part coming out of the roller cavities 8 can, if necessary, be refilled into the comminution device if the parts are still too large.
  • a separate drive of the screw conveyor 17 is also possible.
  • a helically coiled strip can also be provided, which surrounds the shaft 14 and, due to its helical spring-like design, can also be moved axially, which can result in an improved clearing effect.
  • a similar design of the single comminution roller is provided. This also has a cavity and is open at least on one side, with a clearing element also clearing out material that is pressed into the cavity.
