Definitions

  • the invention relates to a solid bowl screw centrifuge with a mounted on the two end faces, rotatable about a horizontal axis, drivable drum and a coaxially rotatably mounted therein, with a differential speed relative to the drum drivable screw conveyor, wherein the drive comprises a multi-stage planetary gear, the Housing jacket with the drum shell and the output shaft is connected to the screw conveyor.
  • the housing of the multi-stage planetary gear rotates in operation about the horizontal axis of rotation of the drum. Since the gear housing is connected to the drum shell, these components have the same speed.
  • Solid shell screw centrifuges are known in which the epicyclic gearing with the drum is arranged between the drum bearings or outside the drive-side drum bearing.
  • the natural frequency of the drum is one of the limiting factors for the maximum possible drum speed.
  • the internal gearbox reduces the maximum length of the drum by the gear width. Because of the high torques in large worm centrifuges, it may be necessary to perform the epicyclic gearboxes in multiple stages, whereby their width is still increasing. On the other hand, the high torques but also lead to such large diameters of the transmission output shaft that an outboard gearbox is out of the question because of the associated disadvantageous bearing size.
  • the invention has the object of providing a screw centrifuge of the type mentioned in such a way that high circumferential speeds of the drum and large drum diameter are possible when using multi-stage planetary gears.
  • the gear-side drum bearing accommodates the intermediate piece and a shaft connecting the gear stages.
  • the diameter of the intermediate piece thus corresponds to the inner diameter of a suitable drum bearing.
  • At least the last gear stage is arranged with the largest torque with the drum between the drum bearings, so that the transmission output shaft with the largest diameter does not have to be performed by the gear-side drum bearings and the transmission width only partially affects the bearing distance of the drum
  • the other gear stages can be designed as an external gear unit.
  • the gear housing must be formed in two parts, so that the bearing can be mounted in the region of the intermediate piece.
  • the solid bowl centrifuges used in the Fig. 1 to 6 have a drum 1 which is rotatably mounted about a horizontal axis 2.
  • a screw conveyor not shown, coaxially arranged and also rotatably mounted about the horizontal axis 2.
  • the drive of the screw conveyor via an output shaft 3 of a multi-stage planetary gear 4, which in the solid bowl screw centrifuge after Fig. 1 is arranged with the drum 1 between the bearings 5.6.
  • the planetary gear 4 is provided outside of the transmission-side bearing 5.
  • Embodiments of the construction according to the invention are in the Fig. 3 and 6 demonstrated.
  • the gear-side drum bearing 5 between the stages 7 and 8 of the epicyclic gear 9 is arranged.
  • the gear housing 10, which rotates during operation, is connected to the drum shell 11 and has, in the region of the gear-side drum bearing 5, a cylindrical intermediate piece 12 whose diameter is reduced relative to the housing parts of the gear stages 7 and 8.
  • the bearing 5 thus accommodates the intermediate piece 12 and a shaft 13 connecting the gear stages 7 and 8.
  • the intermediate piece 12 is divided transversely to the axis of rotation 2 and indeed for assembly reasons.
  • the drum shell 11 may have a diameter which is greater than 1,000 mm.
  • the ratio between the center distance L of the bearings 5 and 6 of the drum 1 and the diameter D of the drum shell 11 (L / D) may be greater than 3.8.
  • the torque between the drum and screw conveyor may e.g. 100,000 Nm.
  • the circumferential speed at the inner radius of the drum shell 11 may be greater than 105 m / s.
  • the inventive arrangement of the gear-side drum bearing between two stages of a multi-stage planetary gear is particularly suitable for very large decanters.
