Definitions

  • the present invention relates to a novel sorter according to the Preamble of claim 1.
  • Such sorting plants for the separation of for the production of paper, Cardboard u.
  • Provided fiber, in particular wood material from disruptive Particulate contaminants are in various embodiments become known and are used worldwide in the paper industry.
  • Sorters are known in which blades arranged on a rotor in Have an aircraft wing similar cross-sectional shape, which starts from a bulge-like curve in the direction of rotation, backwards converges and ends in a narrow, teardrop shape. These wings extend are in the form of strips and have a length corresponding to the rotor or sieve basket Length on. In general, a cylindrical rotor is provided. Both known sorters is that for the passage of the fiber particle suspension provided screen basket facing surface of the wing in the way curved that the radial distance between the functional Wing surface and the facing screen basket surface in the leading area of the Wing first reduced to a minimum.
  • sorters In addition to the state of the art, there are two basic types of sorters exist, namely on the one hand sorters with one from the inside Sorting material suspension for loadable sieve basket and within the sieve basket horizontal blades, so “centrifugal sorter”, and on the other hand with sorter rotating outside the strainer basket and the same a short distance outside sweeping wings, with these so-called “centripetal sorters” the goods to be sorted are fed to the screen basket from the outside and the removal of the cleaned fiber suspension from the inside.
  • the rotary shaft of the rotor carries wings in the inlet-side or upper area of the strainer basket, such as a star or disc-shaped carrier with downwardly projecting projections on which the wings rotating around the strainer basket are attached.
  • the present invention is based on the observation that the previously usual design of the screen-near surface of the wing in the form of a Wing area, in particular in the leading area of the wing intended reduction in distance between sash and strainer, neither from fluidic and energetic view still with regard to effectiveness of Separation process, throughput quantities and separation performance is optimal.
  • the invention thus relates to a sorter as described at the beginning, the by the features stated in the characterizing part of claim 1 is characterized.
  • the wings arranged and designed according to the invention practice their entire length and extension in the direction of rotation, i.e. over the entire surface, in the Fibrous suspension a relative to their other pressurization in the Housing of the sorter lower pressure or "negative pressure". With that the Suck back on a part of the already through the openings of the strainer passed fiber suspension increased, and there is a Backwashing through the openings in the strainer basket. Thanks to the improved take-off of the retained impurities improves the separation behavior and the separation performance of the sorters according to the invention. By the staggered The arrangement of the individual wings is practically at any time at any point swirling of the strainer basket and thus cleaning of the strainer basket surface. In the case of a rotary paraboloidal rotor, the flow from Entry can be managed cheaply.
  • the run-up area or the leading area of the wing includes practically no or only a small angle with the minimally spaced screen basket surface. Because of this, a high backwashing rate and an effective lifting of particle material from the screen basket surface can be achieved within the ranges of the intended angles due to an increased suction effect.
  • the curvature of the surface of the wing facing the strainer basket is important for the desired backwashing or the suction effect. It has been shown that an improved degree of backwashing can be achieved if different curvatures are formed in the front and rear areas of the individual wing in the direction of rotation, i.e. when the features of claim 5 are realized, the choice of different curvatures for the different areas of the the wing surface facing the screen basket allows a good adaptation of the wing surface to different operating conditions and material compositions. In this context, the features of claim 15 are also advantageous.
  • the rotor itself can be made in one piece.
  • one Be embodiment in which a plurality of individual rotor modules to a rotor any axial extent are composed, as in claim 13 is specified.
  • the invention further relates to a wing according to the preamble of claim 16.
  • a wing according to the preamble of claim 16.
  • the conventional wings it is to be regarded as a disadvantage that they are solid and heavy, in particular because these wings are of wing-shaped cross section.
  • the wings mentioned are characterized according to the invention by the features stated in the characterizing part of claim 16. With such a structure of the wings, it becomes possible to manufacture the wings in a lightweight construction and to give the wings the desired shape in a simple manner, and to adapt them to different purposes.

Without appropriate countermeasures, the openings 204 would become clogged and the passage of the fine-fiber, fine-particle suspension free of foreign particles would be prevented.
