Definitions

  • the invention relates to a screening device according to the preamble of claim 1.
  • banana sieves This refers to sieving devices in which the sieve surface is subdivided over the sieve length into individual sieve surface sections, each of these sieve surface sections having a different inclination within the sieving machine.
  • Such constructions are preferably chosen when larger feed quantities are to be separated according to grain sizes and the separating cut is in relative proximity to the largest grain of the grain size Feedstock is.
  • the advantage of such screening machines is that it is possible, due to the different inclination and thus different conveying speed of the material to be screened to keep the bed height of the screenings over the entire length of the screening machine substantially the same, although by the screening and passing through the fine fraction through the screen fabric is less and less material to promote on the screen deck and is seven.
  • a uniform bed height of the screenings is for effective screening of great advantage, since otherwise close to the end of the screening machine, the particles lying near the separating cut only jump on the screen deck and have no way to find through a mesh of the screen fabric.
  • Such screening machines are known, for example, from EP 0 197 191, EP 1 142 651 and WO 92/00148.
  • the aim of the invention is to combine the advantages of these two screening devices. This is done in such a way that in a known manner in a screening machine, which is for example by an imbalance drive vibrated, an additional vibration system is installed, which is excited by the vibration of the screening machine and in this way screening mats, the are connected on the one hand with the screening machine and on the other hand with the second oscillating system, alternately stretched and relaxed.
  • the second oscillating system which is excited by the vibration of the screening machine, is designed according to the characterizing features of claim 1.
  • the screen surface which always represents a plane in all known tensioning wave screens, is designed as a curved plane in the new screening device, in particular as a segment of a cylinder jacket.
  • the screen surface on the task side has a higher Inclination as on the delivery side, which in addition to the well-known Spannwellensiebterrorism also gives the advantage of a banana screen.
  • this form of the screen surface it is possible to design by the installation of spring elements, an additional vibration system that can be brought by the vibration of the screening machine in a kind of pendulum oscillation, which is very easy the Spannwellensieb bin achieved.
  • the characterizing features of claims 2 to 10 relate to advantageous embodiments of a vibration system of this type.
  • FIG. 1 shows schematically the structure of such a screening machine.
  • the screen box (1) consisting of the wire cheeks 1.1, 1.2 and between the wire cheeks connecting them first cross member 1.3, supported by spring elements 6 on brackets.
  • This is vibrated by an imbalance drive 4.
  • a holding device 1.4 is constructed, which has at its upper end a pendulum axis 2.2 (eg a shaft) for a pendulum-like construction 2.
  • This pendulum-like construction 2 consists on the one hand of the pendulum arms 2.1 and on the other hand from the receiving pieces 2.4 for relative to the screen box 1 movable second cross member 2.3, which pass through window-like openings 1.6 through the screen box.
  • the cross members 1.3 and 2.3 can be arranged approximately so that they can be considered as generatrices of a cylinder jacket whose axis corresponds to the pendulum axis 2.2. Between each of the cross members 1.3 and 2.3, the strip-shaped screen mats 3 are clamped. Furthermore, spring elements 5a can be installed between the screen box 1 on the one hand and the pendulum-type construction 2 on the other hand in order to be able to influence the oscillation amplitude of the pendulum oscillation with respect to the fundamental vibration of the screen box 1.
  • the pendulum-like construction 2 Due to the oscillatory movement of the screen box 1, the pendulum-like construction 2 is also excited to a vibration and by suitable choice of dimensions or by the additional installation of spring elements, the amplitude of the pendulum-like construction 2 can be influenced.
  • the screening device is loaded with screenings on the feed side A, wherein the unswept material leaves the screening device on the delivery side B.
  • FIG. 1 Another embodiment is shown in FIG.
  • the receiving pieces 2.4 are guided via spacer elements 7a in guide elements 8.
  • spring elements 5c On the guide elements, or to position them on or in the vicinity of the receiving pieces 2.4, as shown in FIG.
  • the screening device according to the invention thus combines the advantages of a tensioning wave sieve with those of a banana sieve and is particularly suitable for sieving sieving difficulties.
