Definitions

  • the invention relates to a device for shredding waste with at least one parallel shaft pair driven by a drive device, on the shafts of which intermeshing and mutually rotatable shredding tools are arranged, the shafts being arranged in an approximately horizontal plane during the shredding operation in such a way that the shredding tools approximately Form a funnel-shaped feed zone, in which the waste to be shredded is held due to its gravity and the direction of rotation of the shredding tools and is brought to shredding between the shredding tools.
  • Swiss Patent No. 100 710 shows a device for comminuting rubbish with comminuting rollers running against one another. It is known that a major problem with waste shredding devices is that material and parts with strength properties which vary within a wide range are mixed. There is a risk that parts that cannot be shredded, such as pieces of metal or large stones, are fed in and damage the shredding tools.
  • one of the rollers be mounted laterally displaceably and pressed against the other roller by spring pressure. It is disadvantageous that the contact pressure of the spring is limited on the one hand and the roller begins to deflect by a small amount even with slight increases in pressure.
  • the invention is based on the object of avoiding the disadvantages of the known, in particular thus creating a device of the type mentioned which, with a simple mechanical structure, reliably removes bad or not Crushable parts enabled and still allows crushing with high and highest torques.
  • this object is primarily achieved in that at least one of the shafts is connected to a swivel arrangement and can be pivoted in parallel from the operating position in such a way that the feed zone is inclined to the vertical for ejecting waste which is difficult or not comminutable in the feed zone.
  • a pivoting or tilting movement of a shaft pair can be carried out without the connection of the shaft bearings, e.g. in a frame that would need to be separated.
  • the frame arrangement can be designed so rigidly and statically solid that there is no change in the relative position of the two shafts even at high torques and bearing forces and thus a constant distance between the shredding tools can be ensured even under difficult operating conditions. This guarantees both low-wear operation of the shredding tools and a constant particle size of the shredded waste.
  • the inclination of the feed zone formed by the comminution tools towards the vertical can obviously be achieved both by lifting the shaft pair on one side and by lowering the shaft pair. It is particularly advantageous if the bearings of the shaft pair are fastened on a common frame and if the frame is connected to the swivel arrangement for swiveling at least one shaft of the shaft pair out of the horizontal operating position.
  • a particularly simple construction can be achieved if the frame is arranged so as to be pivotable about the axis of a shaft, so that only the other shaft of the shaft pair is raised or lowered.
  • the shaft can obviously be displaced to such an extent that the pair of shafts lies vertically one above the other in the ejection position.
  • the pivoting takes place beyond the vertical, in order to reliably eject parts located between the shredding tools.
  • the ejection process is supported if at least one of the shafts of a pair of shafts can be driven in the opposite direction by the drive device. In particular, if parts are already jammed between the shredding tools, the ejection process is made easier by counter-rotating drive.
  • the device can advantageously be automated if a sensor for monitoring the comminution torque and a comparison device for determining a predetermined maximum value of the torque are provided on the drive device and / or on the shafts, and if the swivel arrangement for swiveling the shaft pair into the ejection position is connected to a control device when the maximum torque is reached. In this way, a fully automatic shredding operation can be achieved, which guarantees a uniform particle size and only allows those parts that would damage the shredding tools to pass through uncrushed. It is advantageous if the drive device has a direction of rotation reversal device, which is provided for reversing the direction of rotation when the maximum torque is reached.
  • the invention can be implemented particularly advantageously if the shaft pairs are driven by a hydraulic motor and if a sensor is provided for monitoring the torque, which sensor measures the hydraulic pressure and thus indirectly the comminution torque.
  • the device according to the invention can be operated particularly efficiently if, when the maximum torque is exceeded for the first time, the shafts are not initially shifted directly into the ejection position, but if only the comminution tools are initially driven in the opposite direction. Often, an increase in torque simply results from parts of the waste jamming in an unfavorable position between the shredding tools. By driving in the opposite direction and renewed drive in the operating direction, it can be achieved that the particles come between the crushing tools in a different position and in many cases are then crushed without the maximum torque being reached again. Only when the maximum torque is still reached even after one or more reversing cycles can the swivel arrangement for ejecting the goods located in the feed zone be actuated.
  • a device for reducing waste has two rollers 2 equipped with grinding tools 1, which are mounted in a frame 4 by means of shafts 3.
  • the shafts 3 are driven in opposite directions by two hydraulic motors 5 (FIG. 4), so that the waste introduced between them is shredded by means of the shredding tools 1.
  • the two rollers 2 form between them a feed zone 6, in which the waste introduced due to the force of gravity and the direction of rotation of the shredding tools 1 is held until it gets between the rollers 2 and is shredded there by the shredding tools 1 and ejected downwards.
  • the shredded waste falls, as shown schematically, on a conveyor belt 7 and is transported there.
  • the frame 4 is, on the one hand, rotatably attached to a support 8 so as to be pivotable about the shaft of a pair of rollers, and is held in the horizontal position on the other side by a telescopic arrangement 9.
  • the frame 4 can be lowered by relieving the telescopic arrangement (FIG. 3) such that the two rollers 2 lie approximately vertically one above the other and the feed zone 6 is inclined in such a way that this is between them Any shredded material falls out and damage to the shredding tools 1, the rollers 2 or the hydraulic motors 5 is avoided.
  • the ejection of the non-crushable part can be made even easier if the rollers 2 or the shafts 3 are driven in the opposite direction during the ejection process. Once the ejection is complete, the frame 4 is evidently brought into the horizontal position again by the telescopic arrangement 9 in order to continue the shredding operation.
  • the two hydraulic motors 5 can be driven forwards and backwards via a variable displacement pump 13.
  • the pressure in the hydraulic lines 10 is monitored by a pressure monitoring device 11. As soon as the pressure in the hydraulic line 10 exceeds a certain adjustable value, a controller 12 responds for the reversing.
  • This controller 12 controls the variable displacement pump 13 and reverses the direction of rotation of the hydraulic motor 5. After a few revolutions (adjustable time) in the reverse direction, the controller 12 controls the variable displacement pump 13 again in the original direction of rotation. If the pressure in the pressure monitoring device 11 rises again above the set value, the whole process is repeated. The number of controls is registered by a counter and controller 15 for the unfolding. As soon as an adjustable number of reversals (e.g. three) has been made, the pivoting process is triggered by this controller 15. One or both of the variable displacement pumps 13 reverse, the valve 16 is actuated so that the hydraulic cylinders 17 extend the telescopic arrangement 9 and produce the frame 4 in a vertical arrangement (FIGS.
  • an adjustable number of reversals e.g. three
  • the invention provides a new device for comminuting waste, which is both efficient in operation and simple and safe in construction.
