Definitions

  • the present invention relates to an apparatus and a method for the treatment of waste, especially waste with organic components, with at least one rotatable shredding drum with heavy material discharge.
  • the object of the present invention is therefore a device and a method for processing waste from the beginning to provide the type mentioned, which is a fully automatic and continuous treatment of waste when in use Guaranteed cheaper equipment and less energy consumption.
  • a device for processing waste has at least one shredding drum inside a freely movable grinding media, the or the grinding media by means of a separating device in the comminution drum is held back. Also points the shredding drum has a retaining ring, the unreduced Waste until reaching a corresponding predetermined Retains particle size in the comminution drum.
  • Design of the shredding drum ensures that a fully automatic and continuous preparation of the Waste is possible. Energy consumption is also essential less than in known devices. Since the invention Device can be operated continuously, too very high throughputs can be achieved.
  • the device according to the invention shows the shredding drum in the area of its axis of rotation two opposite openings, the first Opening for the entry of the waste to be treated and for discharge of the crushed organic components of the waste and the second opening for the discharge of the separated inorganic constituents of waste.
  • the device has one of the comminution drums downstream coarse screening device for picking up and screening the crushed organic waste.
  • This coarse screening device a fine sieve device can be connected upstream or downstream. This ensures that possible through the crushing drum sieved residual impurities not separated be, so that for the subsequent biodegradation predominantly pure organic suspension is available.
  • the process according to the invention for the treatment of waste is made using the previously described invention Device operated.
  • a first process step the waste to be processed in the shredding drum introduced, the separation of the inorganic and organic components of the waste takes place.
  • the inorganic Ingredients are opened through a second opening of the shredding drum dissipated.
  • the one in the shredding drum remaining organic components of the waste are in a second process step up to a predetermined particle size crushed.
  • This creates an organic, watery one Suspension coming from the crushing drum onto a coarse screen is carried out.
  • non-crushable organic Components separated.
  • the resulting organic suspension is removed from the coarse screen in a further process step a fine sieve is discharged. After another fine screening of the organic suspension, the resulting low solids water partially returned to the shredding drum.
  • one last process step is the resulting organic Suspended suspension of further biological treatment.
  • the fine screening of the organic suspension before Coarse screening carried out is the fine screening of the organic suspension before Coarse screening carried out.
  • the coarse and / or Fine screening can be designed in several stages.
  • the figure shows a device 10 for processing waste, especially waste with organic components.
  • the device 10 includes a rotatable shredding drum 12 Heavy material discharge, a coarse screening device 26 and one Fine screening device 28.
  • the comminution drum 12 has in inside of it at least one freely movable grinding element (not shown).
  • the grinding media are made usually made of stone or metal balls.
  • the or the Grinding bodies are in the comminution drum by means of a separating device 16 12 withheld. Via a waste entry chute 14, the waste to be processed is disposed of inside the Crushing drum 12 transferred.
  • the comminution drum 12 also has a retaining ring 18 on the uncrushed waste until a corresponding, predetermined particle size in the comminution drum 12 holds back. Furthermore, the comminution drum 12 in the region of its axis of rotation 36 two opposing openings 32, 34 on.
  • the first opening 34 is used for entry of the waste to be processed via the waste entry chute 14 and for the discharge of the crushed organic components of the Descent via a second discharge chute 24.
  • the second opening 32 is used to discharge the separated inorganic constituents of waste via a first discharge chute 20.
  • the separated ones inorganic components, especially the sand content of the Waste are fed to a sand wash (not shown).
  • the coarse screening device downstream of the comminution drum 12 26 takes the discharged from the crushing drum 12 crushed organic waste and carries out screening this through.
  • the coarse screening device 26 has one Sieve mesh width of 8 - 30 mm. Those remaining on the coarse screen 26 coarser organic components are removed and further recycling or disposal. Here it is in particular parts made of wood, leather or Plastic.
  • the device 10 also has one of the coarse screening device 26 downstream fine screening device 28.
  • the one in the coarse screening device 26 already roughly sieved organic suspension is fed to the fine screen device 28.
  • the fine screening device 28 has a mesh size of 0.5 mm to 3 mm on. A part of the low-residue water can over one of the Fine screening device 28 leading to the comminution drum 12 Water return device 30 into the comminution drum 12 be returned.
  • Both the coarse sieve and the fine sieve device 26, 28 can be designed as a tension shaft screening machine be.
  • the waste to be processed in the shredding drum 12 introduced.
  • the separation of inorganic takes place and organic components of the waste.
  • the organic components swim in the upper area of the aqueous suspension forming in the comminution drum 12.
  • the inorganic parts sink and become Opening 32 transported. This can e.g. via a so-called Screw discharge (not shown) take place.
  • the organic Ingredients become up to a predetermined particle size crushed and then transferred to the coarse screen 26 as above already described. After another, finer screening the resulting organic suspension of the other biological Treatment e.g. fed in fermentation towers.
