Definitions

  • the invention relates to a screw press for pressing fibrous material, in particular waste paper, according to the preamble of claim 1.
  • Machines of this type are of simple construction, but are very sensitive to the composition of the material to be pressed and tend to become blocked when the press is at a standstill by caking the compacted material. Furthermore, it is difficult to obtain uniformly compacted compacts with different types of fiber material with machines of this type.
  • the jaws of a pressing tongs are subsequently arranged at the outlet opening of the mouthpiece of the screw press, one of which is fixedly arranged and the other is movably mounted.
  • the movable jaw is opened and closed via a linkage by means of an adjusting means in the form of a power cylinder depending on the pressing pressure occurring in the mouthpiece of the press screw.
  • the object of the invention is to eliminate the disadvantages described and to develop a screw press of the preamble of claim 1 in such a way that the sensitivity to materials and foreign bodies is substantially reduced and the control of the pressing pressure and thus the quality of the compacts is sustainably improved without significant additional measures.
  • this can be made from particularly tough and corrosion-resistant material.
  • the control of the pressing pressure is improved by a control movement in the axial direction, which is superimposed on a radial movement component, when the radial movement increases with increasing distance from the outlet opening or the recess, so that no or only a narrow gap is formed at the recess itself can, whereby the relaxation of the pressing pressure is mainly directed in the axial direction of the pressing tongs.
  • jaws are provided with inserts made of press plates, both of which are then provided with ends that are angled outwards. This makes it possible to use material with particularly high wear resistance and to provide these parts easily replaceable.
  • a particularly simple control of the movable jaw consists in the use of an actuating cylinder, the control movements of which are transmitted with a mechanical linkage.
  • a screw press 1 is installed, to the mouthpiece 6 of which a pressing tongs 9 is connected, which further compresses the material to be pressed and with whose closing force the back pressure for the material to be pressed is controlled.
  • the screw press 1 has a press screw 3, which consists of a cylindrical conveying part 4, which runs in an upwardly open press trough and is overhung at this end - not shown - and from a subsequent conical press part 5, which is in a press insert 7 of a conical Mouthpiece 6 runs, exists and is provided with a screw turn 16 - indicated.
  • the press insert 7 seen in the conveying direction 11 of the material to be pressed, has a conically tapering front region 12 which is provided with fields 22 and trains 23, to which a weakly widening outlet region 13 connects, which ends in an outlet opening 14 at which the jaws 8, 8 'of the pressing tongs 9 are arranged closely thereafter.
  • the press part 5 of the press screw 3 runs in the front region 12 of the press insert 7 with a small circumferential gap 10 from 0.5 to 1 mm to the inner wall 24, into which six cables are incorporated axially and which run out in a cylindrical or slightly enlarged transition region 15 between the front region 12 and the outlet region 13.
  • the compression zone 17 of the press screw 3 essentially ends in this area.
  • a recess 19 is incorporated in the press insert 7, which initially is flat and then rises steeply upwards in one, under one acute angle against the axis 18 tangential plane 30, reaching the compression zone 17 of the screw press 3, ends.
  • the edge 26 of the recess 19 is inclined downwards or backwards from the inner edge 28 to the outer edge 29 of the edge 26 and thereby has a greater width 27.
  • the recess 19 is covered by an extension 21 of the pressing plate 34 'attached to the movable jaw 8' of the pressing tongs 9 and lies with the inner edge 33 'of its end 31' directed towards the mouthpiece 6 on the edge 26 of the recess in the basic position of the pressing tongs 9 .
  • the ends 31 and 31 'of the two press plates 34, 34' of the two jaws 8, 8 'directed towards the mouthpiece 6 are angled a short distance 32, 32' so that when the jaw 8 is stationary, the inner edge 33 of the press plate 34 largely lies tightly against the edge 35 of the outlet opening 14, while the inner edge 33 'of the press plate 34' of the movable jaw 8 'lies largely sealingly on the edge 26 of the recess 19.
  • the movable jaw 8 When actuated by the linkage (not shown), the movable jaw 8 'executes a movement which is the smallest at the recess 19 and larger with increasing distance therefrom and has an axial component in the conveying direction 11 and at the same time a radial component.
  • the inner edge 33 'of the pressing plate 34' is essentially only displaced during this movement on the edge 26 of the recess 19, so that the sealing against the passage of pressed material is largely avoided, the inner edge 33 'preventing the passage additionally favored by leaked pressed material, whereby the movable jaw 8 'can always return to the basic position without being hindered by pressed material which is inserted between the edge 26 of the recess 19 and the end 31' of the pressed plate 34 '.
