Definitions
- the invention relates to a rotary sorter for fiber suspensions contaminated with rejects, according to the preamble of patent claim 1.
- the sorting vanes 4 and the vanes 40 are arranged approximately helically, but the sorting vanes 4 only to the extent that they do not lead directly to an excessive axial conveying component of the fiber suspension along the screen space 3 to the reject outlet 12.
- the lower wedge surface 9 of the wings 4 is twisted, i.e. with increasing distance from the leading edge 11 the wing is bent downwards, i.e. that this surface 9 of the wings leads to a component of motion of the particles hitting them, which goes towards the sieve.
- these sorting vanes 40 are designed differently from the others in that their lower wedge surface 9, like the upper (10), is also non-twisted.
- the partition 19 between the upper and lower surfaces of the wings 4 also contributes to the stiffening of the wings, so that the wall thickness of the wings can be chosen to be smaller.
- the interior of the wings formed by the intermediate wall 19 is closed off by means of a wall extension 19a at the end of the latter.
- the described embodiments of the rotary sorter according to the invention achieve an extremely favorable mode of operation of a sorter by preventing the formation and fixing of fiber mats on the screen basket by the pulsating movement of the material on the screen basket.
- a clogging of the sieve holes, starting from an attachment of material particles at one point, namely from the side of the holes facing the direction of rotation, is progressively prevented by the addition of more and more particles that are stuck there, thereby preventing the pulsating Movement the direction of flow of the particles to the holes is always quite different.
