Definitions

  • the invention relates to a screw press for the treatment of material to be pressed in several successive sections with at least one throttle, the conical throttle ring of which is axially displaceable in the press casing relative to a conical throttle collar on the screw for changing the constriction of the passage cross section for the material to be pressed between two sections.
  • both the throttle ring in the press jacket and the throttle collar on the screw are immovably fastened and the displaceability between the two is brought about by a displaceability between the press jacket and the screw.
  • This can be realized in such a way that the screw is displaceable when the press casing is stationary, or the press casing is displaceable when the screw is axially fixed, or the screw and press casing are displaceable when the press housing is stationary and can also be displaced relative to one another. In any case, there is no longer any sealing of two mutually displaceable parts against the pressing pressure.
  • the application of the invention is not limited to screws with only two treatment sections with only one intermediate throttle. Any number of sections, each with chokes arranged at the transition point, can be provided. These throttles are then all adjusted at the same time by a displacement between the screw and the press casing.
  • a press jacket 1 of a sieve screw press surrounds a rotatable screw 3 driven by a drive shaft 2.
  • the press space formed between screw 3 and press jacket 1, which is fed from an input opening 4, is divided into three sections 5, 6 and 7.
  • Sections are arranged throttles, each of which is formed from a conical throttle collar 8 on the screw 3 and a throttle ring 9 with a roof-shaped cross section in the press jacket 1.
  • the press casing 1 is axially displaceable between partition walls 11 of a fixed press housing and thus relative to the screw 3, which is also axially fixed.
  • the displacement of the press casing 1 and thus the simultaneous adjustment of the throttles is carried out by a drive, not shown, in the press housing, with guides 12 securing the press casing 1 against rotation about its axis.
  • the press jacket 1 is radially fixed at its outlet end by a bearing 13 which is fixed to the housing and which receives the outlet cone 14 of the press jacket 1. At its entry end, it is supported in the press housing and on the screw 3.
  • the screw 3 is composed of a continuous screw core 15 and pushed-on sleeves 16, the parting joints of which are located immediately behind a throttle collar 8 in the conveying direction.
