Definitions

  • the invention relates to a seal for a screening machine, with cross members arranged transversely to the screen direction, between which screen covering areas are fastened in order to be alternately compressed and stretched by the cross bars, the screen covering abutting a seal in the area of the respective machine side wall.
  • a side seal for screening machines is known from DE-A-2 813 630, in which the gap between the machine side wall and the screen covering is bridged by an elongated parallel sealing body on the edges of the screen covering located parallel to the conveying direction.
  • this known side seal it was found that the transverse members to wear out opposite the Se i tenabdichtung reciprocate, the existing foam seal on the underside by constant rubbing.
  • the object of the invention is to provide a seal of the type mentioned, which is wear-resistant and which follows a sequence of movements in both the horizontal and vertical directions of the screen mat and the transverse elements without greater resistance.
  • seal is a plate-shaped corrugated element and the waves or their generators run horizontally and vertically.
  • Such a seal is completely wear-resistant and forms a secure seal for both dry and wet material to be screened, in particular for screenings in fine areas.
  • the seal follows the sequence of movements in the horizontal and vertical direction of the screen mat without greater resistance.
  • the wavy configurations arranged in vertical and horizontal positions can easily absorb the movements.
  • a high degree of flexibility and adaptability of the seal is achieved in that the shafts or their generators are arranged in a U-shape with respect to one another.
  • the two legs of the U-shaped shafts are perpendicular.
  • a further shaft is arranged vertically in the middle between the legs.
  • a horizontal surface protrude below the lower horizontal shaft, on which the screen covering rests. This area is particularly well suited to serve as an attachment to the screen covering.
  • a second horizontal surface is attached above the horizontal surface at a distance which corresponds approximately to the thickness of the screen covering, so that the screen covering is inserted between these two surfaces.
  • a secure hold, good movement absorption and optimal sealing ability are achieved in that the seal has two lateral vertical edges with which they are attached to vertical profiles or posts that protrude from the crossbeams.
  • An optimal transfer of the vertical movements to the seal is created by integrally molding on the outer vertical shafts protruding bodies made of solid material, which lie laterally on the profiles or posts.
  • the upper limit of the seal is wave-shaped. This ensures the linear sequence of movements and prevents spray particles from escaping.
  • the seal 1 consists of a flat or plate-shaped element made of flexible plastic.
  • the plate-shaped plastic has shafts 2, 3, 4, which allow the seal to be easily compressed as well as stretched in the horizontal and vertical directions.
  • the two outer vertical shafts 2, together with the lower horizontal shaft 3, form a U-shape, and thus a U-shaped groove on the side facing away from the material to be screened.
  • Between the two vertical shafts 2 is a central vertical shaft 4, which does not extend to the lower shaft 3, so that the area between the shafts 2, 3 and 4 forms a U-shaped groove 5 on the side facing the material to be screened, which in its dimensions are smaller than the U-shaped groove on the back.
  • edges 6 On both sides of the outer shafts 2 there are vertical surface strips as edges 6 which are fastened to vertical profiles or posts which are fixed on the ends of cross members of a screening machine.
  • This is a screening machine with mutually movable cross members, which alternately reduce and enlarge the area between them, so that the screen element areas located between the cross members are alternately compressed and stretched.
  • the seal On the underside, the seal has a first horizontal surface 7 and above it a second horizontal surface 8 (lip) of smaller size, these forming a distance from one another and thus a groove 9 in which the screen covering can be inserted and glued.
  • protruding bodies or cams 10 are formed from solid material, which protrude laterally in the form of a partial cube and form contact surfaces for the vertical posts or profiles, so that movements of the posts or profiles can be absorbed by them.
  • the top of the seal 1 has a wave-shaped configuration 11 to absorb linear movements and to close the grooves or waves at the top and thus to prevent spray particles from escaping.
