Definitions

  • the invention relates to a screening machine with a screening layer, which is fastened to a plurality of transverse elements arranged transversely to the conveying direction of the material to be screened, of which every second is connected to the same movement system and the intervening transverse elements are at rest or are moved in opposite directions around the area of the between two transverse elements Alternately compressing and stretching the screen covering, the gap between the machine side wall and the screen covering being bridged on both lateral edges of the screen covering parallel to the conveying direction by an elongated parallel sealing body.
  • the object of the invention is to improve a screening machine of the type mentioned in such a way that wear does not occur in the side seals due to the movements of the transverse elements.
  • sealing body is divided into individual sections with two different lengths, the longer sections each extending in each position from the cross element of the one movement system to the cross element of the same movement system.
  • Such sealing bodies which are divided into individual sections, can lie on both end faces between parts which are fastened to these transverse elements above the transverse elements of a movement system. As a result, these transverse elements alternately compress the sealing body without rubbing along it, so that there is no wear.
  • the intervening cross elements of the other movement system or the stationary cross elements can certainly not lead to wear.
  • these sealing bodies are easy to manufacture, easy to assemble and produce a high level of tightness. A particularly secure hold of the sealing body as well as a simple manner of attachment and little wear and tear are achieved if shorter sections arranged above the transverse elements of a movement system are held by these transverse elements, and the longer sections in between lie against the shorter ones at least in the upper area.
  • the shorter sections lie in recesses which are open at the top or are arranged at right angles to the conveying direction and are fastened to the transverse elements. It is preferably proposed that the profiles be trapezoidal and widen upwards. The shorter sections can also be correspondingly trapezoidal.
  • Installation complies with the fact that the sealing bodies do not have to be held individually by gluing or another fastening method. It is sufficient for the longer sections to lie loosely on the screen covering. It is preferably proposed that the end faces of the shorter and longer sections be chamfered, the adjacent end faces of two sections being parallel to one another.
  • FIG. 1 An embodiment of the invention is shown in the drawing. It shows a perspective section of a screening machine with the side wall removed.
  • a working on the tensioning shaft principle screening machine has transverse elements 1, 2, which are perpendicular to the conveying direction of the material to be screened and z.
  • B. trapezoidal steel profiles are formed. Every second cross element 1 is connected to a first movement system I and every second cross element 2 to a second movement system II.
  • the cross elements 1 can also stand still and only the cross elements 2 can move back and forth transversely to their extension in accordance with the arrow 3. This leads to the spaces between the cross elements 1, 2 alternately becoming larger and smaller, and the sieve mat 4 attached to the cross elements made of elastic material being alternately compressed and stretched.
  • a side wall (not shown in the drawing) is arranged on each of the two end faces of all the transverse elements, the end faces of the cross elements and the long side of the screen mat 4 being close to the side wall.
  • 5 sealing bodies are arranged above the sieve mat edge, which consist of plastic foam and are bar-shaped with a rectangular or square cross section.
  • These sealing bodies are divided into longer sections 6 and shorter sections 7, the longer sections 6 always having a length such that they end on both sides at the transverse elements 2 of the same movement system II.
  • the longer sections 6 each cover the cross element 1 of the movement system I.
  • the shorter sections 7 can be on the top of the cross elements 2 or the fastening strips for the screen covering or the screen mat must be attached.
  • a V-shaped or U-shaped profile is fastened along the cross element 2 on the upper side of the fastening strip 8 and receives a correspondingly shaped shorter section 7.
  • the V-shaped or U-shaped profile 10 thus forms an upwardly open, trapezoidal, tapering downward inner space, in which the section 7 having a correspondingly trapezoidal cross section lies.
  • the height of section 7 is greater than that of profile 10, so that section 7 projects beyond profile 10.
  • Both sections 6 and 7 have the same height H and their horizontal tops are aligned with one another.
  • the end faces of the two sections 6, 7 lie against one another at least in the upper region.
