Definitions

  • Another task is to develop a plansifter that is simple and safe horizontal tensioning or relaxation of screens and / or screen stacks allows.
  • An automatic clamping device for stacks of sieves is also made possible in a plan sifter, which is also a start-up control and an automatic, horizontal, controlled retensioning includes.
  • a sieve has a sieve frame 1 with web strips 2 and a sieve fabric 3, the is placed in a sieve box 4.
  • the screen frame is preferably made of aluminum or a PUR foam.
  • the base plate 5 has web strips 6 and also preferably 2 web strips on its outside on, which are designed so that they, on a screen 3 below arranged sieve can be immersed in the ground material layer. In addition to one Stiffening of the base plate 5 cause such outer web strips also lead the ground material on the sieve below it in a plan sifter.
  • the screens arranged in a plansifter 10 in stacks are in the horizontal direction tense or tense.
  • Such sieve stacks are arranged e.g. after in EP-B-584 302.
  • the vertical bracing takes place e.g. by means of a clamping means 11, which is below a ceiling frame 13 is arranged.
  • the drive station is preferably completely within a central part of a plan sifter compartment arranged.
  • the sieves or sieve stacks are horizontal with a defined force braced.
  • an adjustable force is created in two side edges of a sieve initiated so that the sieve with the opposite side wall or the opposite Side edges are pressed against the frame of the plan sifter 10.
  • the adjustable force enables safe clamping while taking into account the respective Operating conditions etc.
  • the force is introduced via an element 15, which divides the force into a component along the direction of force application and angled approximately in the direction of the middle of the screen to the direction of force transmission enables.
  • the corners must also be used for this the sieves have surfaces 7 that correspond to a corresponding surface 17 of the element 15 correspond.
  • the element 15 is therefore preferably designed as an isosceles triangle and is arranged on a longitudinal member 14 with a spring 16. A flexible one System of the sieve box 4 is thus guaranteed in the sieve stack.
  • the opposite corners of the sieve box 4 preferably have analog surfaces 7 on, so that in a system against a spring element a comparable force distribution he follows.
  • the four corners of a sieve box 4 can thus be fixed in a horizontal position. Both too small (insufficient) and too intense (deforming) This prevents tensioning, regardless of the operating conditions (Temperature etc.)
