Definitions

  • the invention relates to a device for the treatment of mixtures of materials according to the preamble of claim 1.
  • Waste disposal particularly of household waste, is constantly forcing municipalities to take ever newer measures. Burning garbage is a viable alternative to garbage disposal, but it simply destroys valuable raw materials.
  • a special form of collecting such packaging of all kinds provides that the consumer collects them in their mixture in a plastic bag. These plastic bags with packaging of all kinds are then picked up by the municipalities from the individual households and sent to a sorting system. At the beginning of the sorting system, the problem arises in which form the packaging can be automatically removed from the plastic bag.
  • the invention is used in a special field of application, the object of the invention being to provide a device for treating such mixtures of materials, which in particular makes it possible, for example, to tear open plastic bags with all types of packaging contained therein and to separate the plastic bags and thus to enable the individual fractions of recyclables to be removed from the sacks.
  • the object of the invention is also to provide a device which is generally suitable for shredding garbage, the process having to be carried out economically and effectively.
  • the invention is based on the main idea that large quantities of waste can only be processed economically in an automatically operating device and corresponding downstream systems.
  • the The device according to the invention has the advantage that, for example, resulting garbage bags with the valuable materials contained therein can easily be separated into the plastic bag and bag contents, so that the material mixture from the plastic bag can subsequently be further processed. It is particularly difficult to obtain a separation of these components, since the large-area plastic sacks would generally clog a conventional screening device.
  • the present invention is based on the main idea that the garbage bags entered into a device are treated in such a way that tear-open knives with different movement sequences on the garbage bag inevitably cause the garbage bag to be torn open.
  • a transport device extending over several meters is created, on which the garbage bag is transported further and torn open during this transport process.
  • the device according to the invention transports the introduced garbage bags over a transport route on which they are torn open at the same time, so that the garbage components fall out of the garbage bag between the tear-open swords and can be disposed of.
  • the treatment device therefore represents a type of transport screen with a bag tearing device and a separation device.
  • the opening of the garbage bags takes place particularly expediently in that the opening swords have a revolving chain, which are equipped with opening knives or opening mandrels, different speeds of the opening knives of the respective opening swords leading to a relative movement with respect to one another, which brings about a reliable opening of the opening rubbish bags.
  • the ripping knives of the respective ripping swords can move in the same direction or in opposite directions to one another at different relative speeds.
  • a rectified movement of ripping swords arranged in parallel leads to a transport movement of the garbage bags attached to one side of the device, which are torn open during transportation by the ripping swords, so that the garbage contained therein between the ripping swords over the distance falls through and the overlying sack can be stripped or removed at the end of the tear-open swords.
  • a blockage of the system by empty garbage bags lying on top is excluded and a simultaneous separation of the garbage components from the sack.
  • the adjacent tear-open swords with drive chains running around them can be aligned parallel and horizontally. However, in a modification of the invention, they can also be fanned out in the direction of transport, so that the distance between the tear-open swords in the direction of transport of the garbage bags placed increases continuously. As a result, in particular the distance at the beginning of the transport route for the garbage bags can be kept relatively small, so that several tear-open swords lying next to one another grip the respective garbage bag and tear it apart. If the garbage bag is torn open, the garbage can then fall between the widening tear-open swords.
  • a slightly increasing arrangement of the transport swords in the transport direction of the garbage bags has the advantage that they remain longer on the transport device of the circulating transport chains during their dwell time. As a result, the treatment time on the garbage bags is increased without extending the transport route. 6/20871 PC17DE95 / 01827
  • the chains are circulated on the ripping swords in the manner of known chainsaws, i.e. On one end of the ripping swords there is a drive wheel over which the rotating chain is guided and driven.
  • Different speeds of rotation of adjacent tear-open swords can, according to the invention, be achieved by different sizes of such drive wheels and / or by different revolutions of the respective drive shafts.
  • each next but one drive wheel for an associated ripping sword is arranged on a common shaft as a common drive, the diameter of the drive wheels of both drive shafts lying parallel to one another being varied. This ensures that adjacent drive swords with different
  • the device according to the invention is advantageously designed with a chain tensioner for each revolving chain, the chain tensioner having a control device with automatic switch-off, which switches off the transport of the chain completely or intermittently as soon as the chain jams to a considerable extent.
  • the invention is further advantageously expanded by several, for example, parallel hold-down devices, which are e.g. B. are each above the ripping swords in an obliquely inclined arrangement.
  • the applied garbage bags are therefore grasped by the transport device of the tear-open swords, and pulled in a wedge shape under the inclined hold-down devices, which in turn can be equipped with tear-open knives on their undersides.
  • the hold-down device can be rotatably or pivotally mounted at a front end about a common axis of rotation, so that the rear area lying in the direction of transport can be pivoted up and down. This prevents jamming of the waste components.

  • the tear-open swords 10 to 14 lie approximately horizontally aligned at a distance a * ⁇ next to one another, the distance being approximately 120 to 180 mm.

  • Tear-open swords 10 to 14 can be varied widely, so that the tear-open knives or tear-open bolts 21, which are arranged on the chains 16, of adjacent tear-open swords perform different movements.

  • the garbage bag opened in this way gradually releases the contents of the mixture of valuable materials contained therein, so that this content falls down through the intermediate space 31 between the respective tear-open swords 10 to 14 and occurs on a conveyor belt 32 arranged below the receptacle 4.
