Definitions

  • the present invention relates to a press screw separator for separating solid components from a pulp containing solid and liquid components, as well as a wear ring for the press screw separator.
  • Press screw separators are used to squeeze out a pulp.
  • the slurry may in particular be liquid manure or sewage.
  • the wastewater can come from both municipal and industrial plants, which should always be separated into solid and liquid components.
  • a cylindrical screen is arranged, within which a screw rotates.
  • the pulp is conveyed through the press screw separator and pressed.
  • the liquid portions of the pulp pass through the sieve, while a solid grafts within the sieve.
  • the Feststoffpfropfen is conveyed to one end of the press screw separator to be outputted there.
  • the document DE10342684 A1 shows a previously known press screw separator.
  • this press screw separator a plurality of slots are formed at the junction of the housing in the screen chamber.
  • the slots form a thrust and shear favorable angle to the over-rotating screw.
  • the slots are integral elements cast into the housing. It is an object of the present invention to provide a press screw separator, which is designed wear-optimized in cost-effective production and low-maintenance operation.
  • the screw extruder comprises a housing having an inlet chamber and a screen chamber.
  • the inlet chamber goes into the screen chamber.
  • an inlet for the slurry, an outlet for the solid components and a drain for the liquid components are formed on the housing.
  • a, in particular cylindrical, sieve is arranged in the screen chamber. Through the inlet chamber and into the sieve a snail extends.
  • the worm is rotatable about a longitudinal axis of the screen. With the rotary motion of the screw, the pulp is squeezed out along the screen.
  • the drive of the screw is preferably via a motor, wherein the inlet chamber is located between the engine and the screen chamber.
  • a wear ring is arranged at the transition from the inlet chamber into the screen chamber.
  • the worm extends through this wear ring.
  • the wear ring is mounted replaceably on the housing.
  • the wear ring is attachable to the inlet chamber.
  • On the inner circumference of the wear ring a plurality of cutting edges are formed. The very narrow gap between the outer edges of the screw flights and these cutting edges leads to a shearing action and thus to a division of long-fiber solids in the pulp. As a result, clogging of the screen is largely avoided.
  • the wear ring is removably attached to the housing and can be easily replaced after appropriate wear. It is preferably provided that the wear ring is arranged as an axial stop for the wire. For this purpose, it is particularly provided that a largest diameter of the wear ring is larger than a smallest diameter of the screen. One end of the screen can thus rest against the wear ring.
  • the wear ring according to the invention thus serves with its cutting edges not only for cutting long-fiber components of the pulp but also serves as an axial stop for the sieve. Even such an axial stop for the screen is subject to increased wear. With only one component, namely the wear ring according to the invention, therefore, two parts subject to wear of the press screw separator, namely the cutting edges and the axial stop, are formed.
  • the wear ring has a first length.
  • the entire screw has a second length.
  • the two lengths are measured in the longitudinal direction of the screen. It is preferably provided that the first length is a maximum of 10%, preferably a maximum of 5%, of the second length.
  • the wear ring and the cutting edges are arranged in front of the wire and do not extend into the wire.
  • the wear ring is therefore only in the transition region from the inlet chamber into the sieve chamber and does not extend into the sieve. In particular, in this transition region, the cutting edges of distress, since here the long-fiber components can be processed before entering the sieve.
  • the wear ring is preferably screwed to the housing.
  • a plurality of fittings are provided which extend parallel to the longitudinal axis of the screen.
  • the screw connection allows easy replacement of the wear ring.
  • the wear ring is a one-piece, closed ring.
  • the cutting edges are an integral part of the closed ring.
  • the entire wear ring is a cast component.
  • this cast component is fitted into the housing.
  • the invention further includes a wear ring for the press screw separator.
  • This wear ring is used in a press screw separator as described above.
  • the wear ring as a separate, economically tradable component is designed to be arranged at the transition region from the inlet chamber into the screen chamber.
  • the wear ring is fastened interchangeable.
  • On the inner circumference of the wear ring a plurality of cutting edges are formed.
  • FIG. 1 shows a partially cutaway press screw separator according to an embodiment of the invention
  • Fig. 2 shows a detail of Fig. 1
  • FIG. 3 shows the section A: A according to FIG. 2.
  • the screw extruder 1 comprises a housing 2.
  • an inlet chamber 3 and a screen chamber 4 are formed.
  • the inlet chamber 3 passes into the screen chamber 4.
  • the housing 2 comprises an inlet 5 at the inlet chamber 3. This inlet 5 serves to fill in a cloud.
  • an outlet 6 and a drain 7 are formed. The outlet 6 is used with a corresponding mechanism for the intermittent execution of the separated solid. About the drain 7 of the separated from the slurry liquid component flows from the housing 2.
  • a gear 11 is flanged.
  • the transmission 11 in turn is driven by a motor 12.
  • the inlet chamber 3 is located between the gear motor unit and the screen chamber 4.
  • a screw extends 9.
  • a hollow cylindrical sieve 8 is arranged in the screen chamber 4. Both the sieve 8 and the screw 9 extend along a longitudinal axis 10.
  • the pulp to be separated is introduced via the inlet 5.
  • This pulp is conveyed by the rotating screw 9 in the direction of the outlet 6.
  • a solid plug forms in the region of the outlet 6.
  • the corresponding liquid constituents of the pulp pass through the sieve 8 radially outwards and flow off via the outlet 7.
  • Fig. 2 shows in detail the design and arrangement of this wear ring 13.
  • the wear ring 13 is an integrally cast and machined machined component.
  • On the inner circumference of the wear ring 13 a plurality of ribs 14 are formed.
  • At its outer periphery of the wear ring 13 comprises an angular range 15.
  • This angular range 15 of the wear ring 13 is fixed in the housing 2.
  • the attachment takes place via screw 16 by means of these screw 16, the wear ring 13 is readily replaceable.
  • Fig. 2 shows that the diameter of the screen 8 and the diameter of the wear ring 13 are selected so that the sieve 8 abuts the wear ring 13 in the axial direction.
  • the wear ring 13 thus serves as an axial stop of the screen.
  • Fig. 3 shows the marked in Fig. 2 section A: A.
  • each rib 14 forms two cutting edges 17 each.
  • the cutting edges 17 are therefore formed by the ribs 14.
  • the cutting edges 17 extend parallel to the longitudinal axis 10.
  • the outer edges of the helices of the screw 9 move with only a very small distance over these cutting edges 17 away.
  • a corresponding shear load acts, in particular on long-fiber portions in the pulp during the transition from the inlet chamber 3 into the screen chamber 4.
  • a plurality of ribs 14, preferably more than 20, are provided, the narrow gap between the cutting edges 17 and the outer edges of the helices of the screw 9 is preferably 0.1 to 0.5 mm.
  • Fig. 2 shows in the direction of the longitudinal axis 10 measured a first length 18 of the wear ring 13.
  • Fig. 1 also shows in the direction of the longitudinal axis 10 measured a second length 19 of the entire screw 9.
  • the comparison of these two lengths 18, 19 shows that Wear ring 13 in the direction of the longitudinal axis 10 only a small fraction of the second length 19 of the screw 9 occupies.
  • the first length 18 is at most 10%, preferably at most 5%, of the second length 19.
  • FIG. 2 shows that the wear ring 13 does not extend into the sieve 8. Rather, the wear ring 13 ends before the sieve 18 and thus can also form a stop for the sieve 18.
