Definitions

  • the invention relates to a modular sieve system with a support structure, which has support elements, and with interchangeably arranged, reinforced sieve elements made of elastic material, which have on their underside with the support elements cooperating clamping elements made of a castable plastic, in particular a polyurethane .
  • a sieve tray of this type is generally used for sieve well, for example to drain and / or classify rock, sand, gravel or the like.
  • Such a sieve tray known from DE-AS 28 49 838 consists of a support frame with support elements having a C-shaped cross section and of sieve elements which are made in one piece from a rubber-elastic plastic.
  • the Shore hardness of the plastics used mostly polyurethane (PUR), with high abrasion resistance properties is above 80 A, usually around 90 A.
  • PUR polyurethane
  • the use of sieve trays with sieve elements made of these plastics for the sieving of minerals, especially in the wet sieving process has brought excellent results.
  • the invention has for its object to provide a simple in the manufacture, assembly and storage of sieve plate with high sieving performance, the sieve elements have a high stability even with very abrasive material.
  • the reinforcement is not designed in the form of an underlying support plate, but as rods, profiles, wire ropes, coarse-meshed grids or the like, which is preferably completely embedded in the plastic.
  • the rubber plate is connected to the embedded reinforcement in the area of its webs free from sieve openings, between which there is at least one field of sieve openings. In the case of strip-shaped sieve elements, the reinforcement preferably extends at a right angle.
  • the clamping elements form a substantially one-piece grid or a one-piece grate on which the rubber plate is arranged directly, completely and permanently.
  • the automatically clamping clamping elements are arranged on at least two mutually opposite side edges of the rubber plate and if the clamping elements each have an inner web running parallel to the associated side edge of the rubber plate, to which an outer extension is assigned, with between Web and inside of the extension a groove is formed.
  • the production of the sieve elements can be made even more economically and easily if the rubber plate is completely prefabricated before it is connected to the clamping elements and the reinforcement which may be present.
  • the rubber plate can e.g. from a larger unit, e.g. a plate or a roll, cut off and then punched.
  • An adhesion promoter inserted between the rubber plate and the clamping elements increases the strength of the connection between the relevant parts.
  • FIG. 1 A section of a sieve tray according to the invention is shown in FIG. 1.
  • the sieve bottom has a support structure 1 with a frame 2 and with support elements 3.
  • the support elements 3, which are c-shaped in cross section, can be connected rigidly or interchangeably to the frame 2.
  • the preferably strip-shaped sieve elements 4 of the sieve bottom have a reinforcement 5.
  • clamping elements 7 are arranged flush with the side edge of the sieve elements 4. With the help of the clamping elements 7, the sieve elements are automatically clamped on the support elements.
  • the automatically clamping clamping elements 7 are each arranged along the two opposite side edges of the sieve element 4 in question. They each have an inner web 8 running parallel to the associated side edge, to which an outer extension 9 is assigned.
  • the sieve elements 4 each have a rubber plate 11 as a wear layer.
  • the clamping elements 7 and the reinforcement 5 form a one-piece coarse grid or a one-piece wide-column grate on which the rubber plate rests as a wear layer.
  • the rubber plate can thus freely swing in zones, which has a positive effect on the freedom from clogging.
  • the rubber sheet is preferably completely prefabricated. To do this, it can be cut from a larger plate or from a roll and sealed with the sieve holes, e.g. by stamping. The finished rubber sheet is then completely and permanently connected to the lower part, which forms the one-piece coarse grid or the wide-gap grate. In order to increase the durability of the connection, an adhesion promoter is introduced between the rubber plate and the grid or grate.
  • FIG. 2 shows a bottom view of a sieve element 4 of the sieve bottom shown in FIG. 1. This clearly shows the lattice or rust structure, formed from the reinforcement 5 embedded in plastic and the clamping elements, which is completely and permanently attached to the underside of the rubber plate.
  • the rubber plate is thus not congruent, but is only supported in a linear manner in the area of its webs 13 free of sieve openings 11. The zones of the rubber plate remaining between the webs 13 can swing freely.
