Definitions

  • This invention relates to vibratory sifters, the term "sifters” being used in a broad sense to include the various sieves, screens and the like by which the materials can be screened, graded or separated.
  • the term "material” is intended to describe solids, liquids, items or any other substances tobe separated by size.
  • material to be separated is supplied to the top of the vibrating screen, oversize material being retained on the top of the screen while undersized material passes through the screen. Oversized material is removed from the periphery of the screen, normally by way of an opening in a peripheral wall surrounding the screen.
  • a sifter comprising a resiliently supported circular chamber having a screen fitted in the base, means for subjecting the chamber and screen to a vibro gyratory action having a three dimensional motion of a rotational character having upward and downward components in the movement, means for collecting undersized material passing through the screen and an aperture through the screen adjacent to and inside the periphery of the chamber through which oversized materials from the top of the screen are dischargeable directly below the chamber.
  • the apparatus comprises a plurality of vertically spaced screen each having a discharge aperture for oversized particles adjacent to and inside its periphery.
  • a discharge chute for oversize material is located beneath the or each aperture, directing oversize material away from the centre of the sifter.
  • the mesh is bonded or otherwise fixed to said peripheral and further frames.
  • Fig. 1 shows a perspective view of a circular screen.
  • the screen comprises a circular peripheral tensioning frame 30 having a mesh 32 bonded, clamped or otherwise fixed to it.
  • a mesh 32 bonded, clamped or otherwise fixed to it.
  • a multiple progressive sifting operation can be achieved by fitting one above the other in the sifting chamber 14, a plurality of screens, the mesh size of which decreases progressively downwards, each screen having fitted therebelow a discharge chute 38 for over size material, each leading to a separate collecting means, the undersize material falling through an upper screen to the next below screen where it is subject to a further sifting operation, the lowermost screen being provided with a collecting pan 18 and discharge chute 20, for undersize materials passing through the lowermost screen.
  • the compression springs 12 on which the vibrating chamber is mounted may be replaced by rubber bushes or any other resilient assemblies.

Claims (8)

  1. Tamis comprenant une chambre circulaire (14) supportée de façon élastique, possédant une grille (16) montée dans sa base, des moyens (12, 24, 26, 28, 30) permettant de soumettre la chambre et la grille à une action vibro-giratoire selon un mouvement tridimensionnel de type rotatif présentant des composantes ascendantes et descendantes, des moyens (18) destinés à récolter le tamisat traversant la grille, caractérisé en ce qu'une ouverture (34) est prévue dans la grille à côté de et à l'intérieur de la périphérie de la chambre (14), à travers laquelle le refus issu du dessus de la grille peut être évacué directement sous la chambre.
  2. Tamis selon la revendication 1, caractérisé en ce qu'est prévue une pluralité de grilles (16) espacées dans le sens vertical, présentant chacune une ouverture de décharge (34) destinée au refus, à côté de et à l'intérieur de leur périphérie.
  3. Tamis selon la revendication 1 ou 2, caractérisé en ce qu'une goulotte de décharge (38) destinée au refus est située en-dessous de l'ouverture ou de chaque ouverture (34), qui entraîne le refus hors du centre du tamis.
  4. Tamis selon la revendication 3, caractérisé en ce que les moyens de récupération (18) destinés au tamisat présentent une base inclinée et un moyen de décharge (20) à la périphérie du tamis.
  5. Tamis selon l'une quelconque des revendications précédentes, caractérisé en ce que la grille (16) comprend un maillage (32) supporté par un cadre tendeur (30) périphérique auquel le maillage (32) est soudé ou fixé d'une autre façon.
  6. Grille de tamis à vibrations, caractérisée en ce qu'elle comprend un cadre tendeur (30) périphérique supportant un maillage (32), qui présente une ouverture (34) destinée au refus qui est tamisé, à côté de ou à l'intérieur du cadre périphérique (30).
  7. Grille de tamis à vibrations selon la revendication 6, caractérisée en ce qu'un autre élément de cadre (36) est fixé au cadre périphérique (30) pour délimiter l'ouverture (34).
  8. Grille de tamis à vibrations selon la revendication 7, caractérisée en ce que le maillage (32) est soudé au cadre périphérique et à l'autre cadre (30, 36).
