Definitions

  • a wood chip chipper of the generic type for comminuting wood chips has become known.
  • a fixed, cylindrical knife ring is fitted to its inner jacket at regular intervals with replaceable knives.
  • a wood chip conveyor with air blades and adjustable counter knives rotates in the knife ring. Due to the effect of the air flow sucked in by the air blades and the centrifugal force, the wood chips are pushed in front of the knife edges largely parallel to the fibers in such a way that they are divided into thin chips in the direction of the fibers.
  • the invention is therefore based on the object of demonstrating a method and a device of the type mentioned at the outset, with which uninterrupted operation is ensured for as long as possible.
  • the invention solves this problem by a method in which the worn knives in use are exchanged continuously or intermittently with sharp knives during operation.
  • the knives are preferably fed as a function of time and / or energy consumption.
  • the device used to carry out the method is characterized in that one or more magazines for receiving the knives are arranged in the longitudinal direction of the knife ring, and that in each case a slide-in or through device is provided for feeding the knives to the clamping plates.
  • the knives are steel strip knives
  • each steel strip knife can be fed from its rolls to its clamping plates in endless lengths, whereby it is wound onto another roll on the removal side.
  • the feed of the knives or band steel knives can be facilitated in that the knives are provided with depressions or perforations pressed in on both sides of their longitudinal axis, into which a corresponding feed mechanism engages.
  • cutting lengths of this type are stacked in magazines.
  • the magazine can be moved so that all knives are fed to their respective clamping plates one after the other.
  • the knife ring can be rotatably supported in a manner known per se, in order to enable new knives to be loaded.
  • this process enables the production of particulate material of constant quality with a preselectable particle size by bringing the factors particle quality and energy consumption into a constant relationship that corresponds to the economic and technological requirements.
  • Chip quality and energy consumption are particularly favorable here.
  • the wood chip chipper 3 consists of a stationary, cylindrical knife ring 4 with a wood chip conveyor 5 which is equipped with counter knives 6 which are movably suspended in their shoe axes 23.
  • the knife ring 4 is equipped on its inner jacket at symmetrical intervals with knife clamping devices D, which essentially each consist of the two clamping plates 80 and 8b.
  • the clamping plate 8a is held by a tension spring 22.
  • the band steel knives 1 have a centering groove 20, into which springs 21 engage, which are held interchangeably in the clamping plate 8a, which in turn is designed as an exchangeable wear part. There is a gap between the clamping plate 8b and the wear lip 8c opposite it Passing through the machined flakes.
  • the band steel knives 1 can be provided with scratches 12.
  • the strip steel knives 1 are fed to the inserting or pulling device 19 from a roll 15 and wound onto a roll 16 on the removal side. Here they are clamped between the clamping plates 8a and 8b.
  • the band steel knives 1 can be fed to the clamping plates 8a and 8b in lengths which correspond to the simple, a fraction or a multiple of a cutting section 2 in use.
  • the cutting sections 2 are stacked in magazines 17, from which they are fed to the respective clamping plates 8a and 8b via the insertion or pulling devices 19.
  • the magazine 17 can also be arranged such that it can be moved in such a way that the band steel knives 1 are successively fed to their respective clamping plates 8a and 8b.
  • the knife ring 4 can be rotatably supported in a manner known per se and brought into a position from which the loading with new steel strip knives 1 takes place.
