Definitions

  • the invention relates to a screening device with screen rollers, which are arranged side by side rotatably drivable on a frame to form a roller screen for sorting screenings in one or more fine grain fractions and one or more oversized grain fractions.
  • the screen rollers are adapted to convey at least a portion of an oversize fraction in roll axis direction.
  • the invention further relates to a screen roller suitable for forming such a screening device as such.
  • a screening device of the type mentioned is for example from the EP 1 570 919 B1 known.
  • the screening device comprises a roller screen with juxtaposed rotationally drivable arranged, intermeshing screw or spiral rollers.
  • a screened material placed on the roller screen is separated into a fine grain fraction falling between these screen rollers, a first oversize grain fraction conveyed onto the screen rolls transversely to the roll axis direction, and a second oversize grain fraction conveyed in the roll axis direction by screwing action of the screen rolls.
  • the first oversize fraction is discharged at one end of the roller screen transversely to the roller axis direction.
  • the screen rollers are mounted only at one end and thus on the fly, so that the second oversize grain fraction can be discharged unhindered at the freely projecting end of the screen rollers.
  • the EP 2 329 891 B1 describes another example of a screening device.
  • the screening device has screen rollers with roller axes in parallel juxtaposed screen discs, which together form a disc screen.
  • the screen rolls of the screen screen are arranged such that the roll axes are inclined obliquely downward from a feed region of the screen screen toward an output region.
  • the relevant oversize fraction is therefore conveyed by gravity in Walzenachsraum.
  • the screen rollers of the screen screen are mounted on both sides, so that precautions must be taken so as not to unduly obstruct the removal of the relevant oversize fraction beyond the axial ends of the screen rollers.
  • the invention is based on a screening device for sorting screenings into one or more fine-grain fractions and one or more oversize fractions, comprising a frame and a roller screen with screen rolls arranged side by side about a respective roll axis and supported on the frame.
  • the screen rollers each have a roller body and one or more relative to the roller body radially projecting screen structures.
  • the screen rollers are designed and arranged such that between the roller bodies of adjacent screen rollers there is in each case a fine-grain screen gap through which a fine-grain fraction falls, while an oversize-grain fraction is conveyed on the roller screen in the direction of the roller axis when the screen rollers are rotated.
  • the one or more radially projecting screen structures of the respective screen roller may be screen discs, in particular screen stars with radially projecting star fingers.
  • Screen discs of this kind are for example from the EP 1 088 599 B1 known.
  • the protruding fingers of the individual screen stars can advantageously be elastically yielding as described in this document, but in principle the screen stars can also be unyielding in their intrinsic properties or have a negligible elasticity in practical operation.

  • screen stars instead of screen stars also simple circular or oval or similarly shaped screen discs can be used.
  • the screen discs of any kind can also be arranged orthogonal to the respective roller axis. In designs with only orthogonally oriented screen disks or other screen structures, the screen rollers are inclined downwards in the roller axis direction into which the oversized grain fraction in question is to be conveyed in order to effect gravity conveyance.
  • the screen rollers or at least a part of the screen rollers of the roller screen are screw or spiral rollers and each have a screen structure radially projecting over the roller body in the form of a helical structure running helically around the roller axis.
  • two or possibly even more helically rotating screen structures can rotate around the same roller body, which together form a multi-layer screen structure of the respective screen roller.
  • the screen rollers each have only a single screw-like circumferential screen structure, so are catchy.
  • a screen structure formed as a helical structure advantageously proceeds continuously the roll axis in question so that its course over the entire axial length or at least the vast majority of the length of the screen structure is mathematically expressed continuously differentiable.
  • the one or more screen structures of adjacent screen rollers protruding radially with respect to the respective roller body advantageously engage one another in a plan view of the roller screen.
  • the screen structures thus protrude into the fine grain sieve gaps formed between adjacent roll bodies through which the fine grain falls, followed by a protruding screen structure or a protruding screen structure section of an adjacent screen roller in a roll axis direction onto a protruding screen structure or a protruding screen structure section of one screen roller.
  • the roll body of at least one of the screen rolls widens radially in an axial expansion section in the roll axis direction so that the width of the fine wire screen gap which the expanding roll body forms with the roll body of an adjacent screen roll decreases in the expansion section in the roll axis direction.
  • the roller axis direction is the direction in which the relevant oversize grain fraction is conveyed to the widening section. While elongated and light parts of the oversized grain fraction are primarily conveyed transversely to the roll axis direction, the oversized grain fraction conveyed in the roll axis direction mainly contains pieces which are compact and heavy in terms of their external dimensions.

  • the groove formed over the fine-grain screen gap with an adjacent roller body becomes flatter and the conveying action of the screen roller in the circumferential direction, transverse to the roller axis direction, becomes stronger.
  • the one or more protruding screen structures have an inclination relative to the roller axis direction and therefore exert a conveying effect on the oversize in the roller axis direction, this axial conveying effect, on the other hand, weakens along the widening section.
