Definitions

  • the invention relates to a sieve plate with thin, flat sieve mats made of rubber-elastic material, which are held by profiles arranged underneath, on the upper sides of which the sieve mats are releasably fastened under tension.
  • the object of the invention is to improve a sieve tray of the type mentioned in such a way that with simple construction and handling, in particular with easy interchangeability, sufficient tension of the sieve mats is achieved.
  • the profiles have a longitudinal recess on the top, into which the screen mats can be pressed together with a cord that lies on the top of the screen mats, the width of the longitudinal recess being less than the diameter of the cord plus twice the mat size.
  • the cord is made of rubber-elastic material.
  • the cord can also have a circular cross section.
  • the profile is a hollow profile.
  • the profile should be U-shaped in cross-section, the upper free leg ends being bent approximately horizontally inwards.
  • the screen mats consist of a band of great length that can be divided into the desired lengths. This makes the screen mats particularly inexpensive to manufacture by the meter. A particularly secure hold and the avoidance of contamination of the interior of the profiles can be achieved if the screen mats have no screen openings in the fastening areas.
  • An advantageous method for attaching the sieve mats to the sieve bottom is achieved if the sieve mat is placed loosely or under slight tension on the top of the profile and is pressed through the cords from above into the longitudinal recesses while taking the sieve mats with them.
  • the sieve bottom has a plurality of support profiles 1 arranged parallel to the top of the sieve mat, which are arranged parallel to one another at regular intervals. At the ends of the profiles 1 are fastened to one another by cross profiles 2. Below this profile 1, a support profile 3 with an L-shaped cross section is welded with the same leg length.
  • the support profiles 1 are hollow profiles with a square cross section, the horizontal top of the profile having a central longitudinal opening 4 which extends over the entire length of the profile 1.
  • sieve mats 5 are placed as tensioning mats, which are manufactured by the meter from plastic, in particular polyurethane, and are cut to a length which corresponds to the width B of the sieve bottom, the sieve mat being cut a little longer to laterally connect it to the to be able to clamp both ends on the first and last profile laterally with screws 7.
  • the sieve mat so loosely placed over all profiles 1 thus also lies over the openings 4.
  • a round cord 6 can then be pressed into the openings 4 from above, which then takes the area of the screen mat 5 lying there into the interior of the profile.
  • the diameter of the cord 6 together with twice the thickness of the screen mat 5 gives a dimension M which is greater than the width of the opening 4, so that after the cord 6 and the associated area of the screen mat 5 have been pressed in, the screen mat 5 is held in place is given on profile 1.
  • the profiles 1 can also have substantially different cross sections, in particular be rectangular or circular.
  • the cord 6 does not necessarily have to have a circular cross section.
