Definitions

  • the invention relates to a device for separating undesired elongated and / or curved scrap pieces from a scrap stream or scrap pile with a higher density With the help of a screen in a vibratory conveyor.
  • a device for classifying an undesired sieve has already been made Metal chips containing coarse material with the help of one with transverse slits provided vibrating or vibrating screen proposed, in which the screen bottom with in Conveying direction longitudinal grooves is provided.
  • the longitudinal grooves have one trough-shaped cross section with a defined flank angle on or Groove cross-section corresponds to an isosceles triangle standing on the tip a defined tip angle.
  • a selective sorting of the coarse material and a largely uniform bulk density of the sieve passage enables.
  • the screenings or the coarse material should initially be given an orientation transverse to the direction of the sieve gaps to ensure a length-dependent sieve passage for later pressing dimensionally stable chip briquettes.
  • Elongated or curved scrap pieces are undesirable in refrigerated scrap because they negatively affect the bulk properties of the goods.
  • Another disadvantage is the formation of low density nests in the feeders of the steelworks, where this cooling scrap is used. If one were to feed the previously characterized device for sieving with this unsorted refrigerated material pile for separation, the hoped-for effect would not be achieved because, due to the given geometric design of the sieve covering, no separation of the so-called fish can take place.
  • the invention is therefore based on the task of sorting out the so-called fish from cooling scrap with a suitable sieve covering in a conventional vibration or Realize vibrating screen in which the separating elements are designed and arranged so that the so-called fish, i.e. the unwanted elongated and / or curved scrap pieces aligned on the one hand and on the other hand by the more rounded and denser ones desired Scrap pieces are separated.
  • the screen covering 2 is a grid-like frame made of several, parallel, transverse to the conveying direction running dividing strips 3 and several, parallel, running in the conveying direction Guide strips 4 are formed, the guide strips 4 on the separating strips 3 projecting over them seated. Geometries, cross sections and openings 3.2 are formed as they are 4 according to the details of y and z.
  • the task-related effect sought by the invention results from the simple yet experimentally proven and surprising peculiarity that on the one hand the expediently formed from angle steel, seated on the dividing strips 3 Guide strips 4 have flat longitudinal strips 4.1 attached to the free angle legs, the distance between them on the free long sides is less than the distance on the Joining points to the angled legs.
  • This different cross-sectional geometry essentially determines the inventive one Effect that is described functionally below.
  • a cooling scrap stream not shown, which is fed to the bottom 5 and which is not shown, essentially rounded scrap pieces and annoying elongated and / or curved Pieces of scrap, the fish, reach the previous one via the distributing feed bars 5.1 screen covering 2 shown in the design.
  • the flank approaches 3.1 of the separating strips 3 prevent braking or hooking the unwanted, even curved fish, which consequently over the screen 2 "swim" until the discharge.
  • the openings 3.2 according to the invention prevent jamming in the conveying direction and in particular threading the fish.
  • An additional rear wall 3.3 counteracts the effort that long pieces of scrap a function-related backward movement of the fundamentally funded forward Fish get into the openings 3.2.
