Definitions

  • the invention relates to a screening machine with a stationary sieve basket, a rotor rotating in the sieve basket and one terminating at an end face of the screen basket Screw conveyor for dosing and feeding one sieving material, with the rotor and screw conveyor are driven by rotation.
  • the invention has for its object a screening machine to create the type in which the rotor and the screw conveyor is operated at optimal speed and can be a simplified cleaning and Changeover enabled.
  • the rotor can drive the screw conveyor with a the material to be screened and the screen effect are optimal tuned speed while the Inflow by setting the drive device of the Screw conveyor is adaptable. In this way, the additional height for one above the inlet funnel arranged dosing device. Furthermore enables the constructive separation of rotor and screw conveyor drive the targeted expansion only for conversion or cleaning necessary components, the axial length of the individual components to be removed is reduced, since the shaft carrying the rotor from the the worm-carrying shaft is separated.
  • the drive device of the rotor at its the Screw end facing away is arranged.
  • the drive device can on the one hand save space installed and on the other hand enables the coaxial arrangement of rotor and screw conveyor.
  • the rotor and the strainer basket for cleaning or to expand the conversion is in further training Invention provided that the rotor together with the Sieve basket and its drive device from the sieve machine housing along a guide device axially is extractable.
  • the rotor is the Sieve basket and the drive device for example by means of the front cover of the screening machine summarized in a constructive unit, which according to Loosen appropriate closures by the axial length the strainer basket or the rotor are pulled out of the housing so that the strainer basket and the rotor are exposed.
  • the guide device preferably comprises at least one, but especially two axially parallel guide rods, the on the rotor, screen basket and drive device existing unit attached and in guides are slidably mounted on the screening machine housing are trained.
  • the pivot axis of the pivot bearing can essentially run perpendicular to the rotor axis and in particular vertically, alternatively, however, it is also possible that the Swivel axis of the swivel bearing with the longitudinal axis of the Guide rod collapses.
  • a screening machine 10 shown in FIGS. 1 to 3 has a tubular, horizontally arranged screw conveyor housing 17 in which a screw conveyor 16 is rotatably mounted. At its left end according to FIG. 1 is the screw conveyor housing 17 in a screening machine housing 11 set while on the opposite right end a bearing plate 21 is attached, the Screw conveyor 16 is mounted and one on the outside Drive device in the form of an electric motor 19 and a transmission 20 carries.
  • the bearing plate 21 is over Detachable closures 31 on the screw conveyor housing 17 appropriate. After loosening the closures 31, the bearing plate 21 together with the motor 19, the transmission 20 and of the screw conveyor 16 as an axial unit according to FIG. 1 pulled out to the right out of the screw conveyor housing 17 become.
  • the screw conveyor housing is on the top 17 an inlet connection 18 via which the material to be screened Material is supplied in a known manner.
  • a rotor 15 arranged in a left-hand side Cover plate 24 is rotatably mounted on the side of the rotor 15 facing away from the screw conveyor 16 is arranged.
  • an electric motor 23 and a gear 32 for the rotor 15 attached.
  • the rotor is of a tubular, horizontally oriented Sieve basket 12 surrounded, also on the Cover plate 24 is held.
  • a collecting funnel 13 formed on the underside in a discharge line 14 for the screenings pass over.
  • the interior of the strainer basket 12 with a further discharge line 22 connected for the coarse material.
  • the front end of the screw protrudes 16 into the strainer basket 12 by a small amount.
  • it faces the screw conveyor End of the rotor additionally with two worm threads 15a trained to effectively screen the material to be screened To be able to feed screen basket 12.
  • the cover plate 24 is on detachable closures 33 on Screening machine housing 11 set. After loosening the fasteners 33, the cover plate 24 together with the screen basket 12 held thereon, the rotor 15 and the Electric motor 23 and the gear 32 according to Figure 1 after left, i.e. to that facing away from the screw conveyor 16 Axially pulled out of the screen machine housing 11 become. While pulling out the cover plate 24, rotor 15, screen basket 12, electric motor 23 and gear 32 existing unit via a guide device guided.
  • the guide device comprises two on the Cover plate 24 held parallel to the rotor axis Spacing guide rods 25 ( Figure 3), each of which two on the screen machine housing 11th trained guides 26 are assigned.
  • the two Guide rods 25 are common across a vertical Pivot axis 27 mounted on the cover plate 24. This allows the cover plate 24 and those located thereon Components after pulling them out of the screen machine housing 11 laterally about the vertical pivot axis 27 swing out so that the strainer basket 12 and the rotor 15 are easily accessible.
  • FIG. 4 shows an alternative embodiment of a screening machine, the first embodiment being similar Components are provided with the same reference numerals.
  • the main difference to the embodiment according to Figures 1 to 3 is that here only a single axially parallel guide rod 29 on the Cover plate 24 is attached, the guide rod 29 formed in a on the screen machine housing 11 Guide 30 runs.
  • the guide rod 29 is over a horizontal pivot bearing 28, the pivot axis with the Longitudinal axis of the guide rod 29 coincides on the Cover plate 24 held.
