Definitions

  • the invention relates to an improvement of the gap sealing in water screw conveyors.
  • Water screw conveyors for wastewater transport are known and are described, for example, in the patent specification DE 34 44440 C2.
  • the screw body is arranged in a trough, and a gap acting as a seal is provided between the trough and the screw body, which gap must be very small and the same at all points.
  • the function of the screw largely depends on compliance with this condition.
  • the gap width results from the difference between the outer screw diameter and the inner trough diameter, provided that the axes of the trough and screw match.
  • the main advantage of this is that, with the same screw and building dimensions, a greater flow rate is achieved without increasing the power consumption because the lower leakage loss improves efficiency, which means considerable energy savings. Further advantageous effects are that the gap seal the screw flights protects against wear and corrosion and increases the lifespan of the gears. By using suitable materials, the gap seal itself has a long lifespan, but if it is worn, it can be replaced without dismantling the screw.
  • Cavities that result when the seal is formed according to the circular shape of the trough, while the outer surface of the aisles is worn away irregularly, are filled according to claim 5 in order to hold the seal, for example by cladding or by pouring with a reactive resin .
  • the seal can consist of a pourable, self-adhesive material, which is poured onto the corridors with a wandering shape.
  • the internal dimensions of the shape correspond to the required external dimensions of the seal.
  • FIG. 1 shows the elevation of a water screw.
  • the gap seal (1) is attached to the outer circumference of the screw body (2).
  • the gap (4) lies between the gap seal (1) and the trough (3).
  • the trough (3) is lined with in-situ concrete (5).
  • FIG. 2 shows a cross section through the screw at the point designated in FIG. 1.
  • FIG. 3 shows an enlarged partial longitudinal section (detail) at the point indicated in FIG. 2.
  • Dimension "b” allows adaptation to the thickness of the screw flights , according to claim 2.
  • the width of the gap (4) is determined by the choice of the dimension "a”.
  • the exact setting of the gap width is an essential part of the invention.
  • the dimension "b” should be chosen so that a tight fit is achieved at all points despite the different thickness of the screw flights.
