Definitions

  • the invention relates to a screen with slot or slot-shaped screen openings parallel to each other and delimited on both sides by profile-shaped webs.
  • the object of the invention is to form unfavorably shaped material, both in Rod-shaped as well as in platelet form, from the general screenings one Certainly separate grain fraction.
  • Such screens can be particularly advantageous in the open casting process (open Mold), in a closed casting process, if necessary under vacuum (closed form) or by injection molding. You can especially in system screen construction and in connection with a blind floor be used.
  • Practice is currently that the unfavorably shaped grains after sorting in the next smaller fraction ends up, or another screen deck for sorting out is installed.
  • the blind floors can be made of metals or reinforced elastomer materials consist, or of pure elastomers with high strength to a Avoid baking of the material due to its flexibility.
  • the sieve (flat grain sieve) 1 has a plurality mounted parallel to one another Ridges 5, the narrow column 4 between them as the same width Form sieve openings.
  • the gap widths and the widths of the webs are therefor are dependent on the separation size of the grain fraction, where the unfavorably shaped grains are to be separated.
  • the webs 5 end on both sides in a crossbar, the webs 5 parallel to the conveying direction 9 are arranged. Between the two crossbars 10 are still Transverse ribs 11 fastened underneath the webs 5, in particular molded on, welded or glued.
  • the webs, crossbars and cross ribs exist preferably made of polyurethane, with 5 reinforcements 6 in the webs, Made of tensile flexible material, in particular made of glass fiber, aramid or Kevlar.
  • the web profile in cross section be rectangular with a semi-cylindrical top or with a roof-shaped in particular trapezoidal top.
  • the cross-section may also be circular, oval or triangular.
  • the profile of the web 5 in the lower region of the widest point tapers downwards in order to close the grain avoid. It is further advantageous if the web profile is at the widest point slightly parallel or slightly conical at first, and then more strongly runs conically to increase the service life / service life of a flat grain sieve increase.
  • the screen shown in Fig. 1 is in particular made in a frame 3 Clamped polyurethane, which is shown in Fig. 3 and its internal dimensions are slightly larger than the outer dimensions of the sieve 1, so that the sieve 1 in the Frame 3 is clamped.
  • the sieve is shorter than the dimensions of the Made inside the frame 3 - up to 2%, in particular 0.5 to 1.0% to a lesser extent.
  • the frame is in turn fastened to a substructure 12 which has an intermediate profile 13.
  • a blind base 7 is attached below the flat grain sieve 1 to receive the grains falling through the sieve and dissipate.
  • Fig. 5 shows the use of such screens in a screening machine
  • the Screen deck in the conveying direction first has screening screens 14 and 15 and only on End of flat grain sieves 1, preferably with blind trays 7.
  • the blind floor can be clamped or screwed or welded, or attached to the adapter, for example. Be from the blind floor 7 the unfavorably shaped grains 16 and from the flat grain sieve 1 Grain fraction 17 removed.
  • Such flat grain screens can also be used for entire screen decks.
