Definitions

  • the invention relates to a sieve, in particular a sieve or a sieve box for Plansichter according to the preamble of claim 1, and a Plansichter.
  • Generic screens in particular Plansichter and the like have a sieve box with a bottom plate, in or on which a sieve-covered sieve frame is placed or placed on (EP-A-330846 or WO-A-93/16815). Such screens already come without a corrugated grid or supporting grates.
  • the sieve frame may be made of light metal or a metal-wood composite and also the bottom plate may be made of metal or plastic (EP-A-584302).
  • DE 2,755,573 discloses a base frame for screen frames in which a collecting frame and a sieve bottom at the corners have Abstumpfungen to allow easier fixation of the collecting frame or the sieve plate in the base frame.
  • the document DE 228064 describes a device for holding together boxes or frames, in particular for clamping the sieve sets of Plansichtern by means of angle levers.
  • pressure angles are positively arranged at the corners of the screen boxes, the tension takes place with the help of schamierartig sitting thereon angle levers.
  • One end of the bellcrank lays thumb-like against projections of the rails carrying the boxes, while the other end is engageable by the tension rods connecting the pressure angle. The tension is done manually.
  • the object of the invention is therefore to develop a sieve which can be tensioned horizontally simply or in a sieve stack.
  • the object is achieved on the basis of the characterizing features of claim 1.
  • Another object is the development of a Plansichters that allows a simple and secure horizontal clamping or relaxing of sieves and / or Siebstapeln.
  • An automatic tensioning device for stacks of sieves in a plan sifter which at the same time includes a start-up check as well as an automatic, horizontal, controlled retightening, is also made possible.
  • a sieve has a sieve frame 1 with web strips 2 and a sieve cloth 3, which is inserted into a sieve box 4.
  • the screen frame is preferably made of aluminum or a polyurethane foam.
  • the base plate 5 has web strips 6 and also on its outer side preferably 2 web strips, which are designed so that they can immerse in the, located on a screen fabric 3 of a sieve arranged underneath Mahlgut harsh. In addition to a stiffening of the bottom plate 5, such outer web strips also cause a guiding of the ground material on the respectively underlying sieve in a Plansichter.
  • the sieves arranged in a plan sifter 10 in stacks are tensioned or tensioned in the horizontal direction.
  • the arrangement of such sieve stacks takes place e.g. according to the manner described in EP-B-584 302.
  • the vertical clamping is carried out, for example, by means of a tensioning means 11, which is arranged below a ceiling frame 13.
  • the drive station is preferably arranged completely within a central part of a plan sifter compartment.
  • the sieves or sieve stacks can be clamped horizontally with a defined force.
  • an adjustable force is introduced into each two side edges of a screen, so that the screen with the opposite side wall or the opposite side edges is pressed against the frame of Plansichters 10.
  • the adjustable force allows a safe clamping under consideration of the respective operating conditions etc.
  • the force is introduced via an element 15, which allows a division of the force in a component along the direction of force introduction and at an angle approximately in the direction of the center of the wire to the direction of force introduction.
  • the corners of the sieves must have surfaces 7, which correspond to a corresponding surface 17 of the element 15.
  • the element 15 is therefore preferably designed as an isosceles triangle and is arranged with a spring 16 respectively on a longitudinal member 14. A flexible system of the sieve box 4 is thus guaranteed in the sieve stack.
  • the opposite corners of the sieve box 4 preferably have analogous surfaces 7, so that in a system against a spring element a comparable force distribution takes place.
  • the four corners of a sieve box 4 are thus fixable in a horizontal position. Both insufficient (insufficient) and too intensive (deforming) clamping is thereby prevented, regardless of the operating conditions (temperature, etc.).
  • the sieves are in the corners exactly on top of each other, so that even with each other a tightness is given.
