Definitions

  • the present invention relates to a wastewater conveying device according to the preamble of claim 1.
  • Eccentric screw pumps have the advantage that their flow rate at the constant speed of the rotary drive is practically independent of the flow resistance in the pressure line, so that the latter can be optimally dimensioned for its respective use. Eccentric screw pumps have the further advantage that high pressures can be achieved.
  • eccentric screw pumps cannot handle large solids. It has therefore already been proposed to connect the eccentric screw pump upstream of a shredder, which will shred all the parts sucked in by the eccentric screw pump (see H. Putz "Abwasserhebeanlagen", trade journal for sanitary, heating, air conditioning, issue 23, 35th JG, 1st edition, Dec. 1980, Berlin).
  • U.S. Patent Re. 29 626 a wastewater conveying device of the type described in the preamble of claim 1 is disclosed.
  • This known wastewater conveying device has a drive motor which is provided with a shaft which is connected to the shaft of the eccentric screw pump via a practically rigid coupling.
  • the shaft of the eccentric screw pump is connected to the rotor of the eccentric screw pump via a flexible coupling tube.
  • the pump shaft carries the cutting head of the comminution device at its lower end.
  • the present invention is based on the object of creating a wastewater conveying device of the type mentioned at the outset which, while taking advantage of the advantages of an eccentric screw pump, enables a simple and comparatively space-saving design.
  • the single figure shows a purely schematic side view and partially in longitudinal section of an embodiment of a wastewater conveying device.
  • the illustrated embodiment is intended for vertical arrangement in a sewage shaft, so that the central main shaft 1, which carries the rotor 2 of an electric motor 3, runs vertically.
  • the electric motor 3 is designed as a submersible motor and is accordingly provided with a cooling jacket 5 surrounding the stator 4.
  • the electric motor has two mutually opposite shaft ends 7, 8, each of which extends through an end bearing 9, 10 of the electric motor 3 and through an end housing part 15, 16 each enclosing two shaft seals 12, 13. In these end housing parts of the electric motor 3 additional ones can be added Shaft bearings included.
  • the housing 18 of a comminution device 19 is fastened to the lower end-side housing part 16 via a flange connection 20.
  • the lower part of this housing 18 merges into the funnel-shaped suction nozzle 21, which is arranged at a distance above the bottom of a sewage shaft, not shown.
  • the comminution device 19 has a cutting head 22 fastened to the lower shaft end 8, on the circumference of which a plurality of cutting knives 23 are fastened at an angle to the longitudinal direction of the device. These circumferential cutting knives 23 work together with a fixed counter-ring 25, which surrounds the cutting head 22 and is attached to the housing 18 of the comminution device 19, for comminuting dye constituents of the waste water.
  • the waste water flows through the gap 26 between the cutting head 22 and the cutting counter ring 25, in which the cutting and / or tearing of the solid components, such as e.g. paper, textiles, etc.
  • a deflecting disk 28 is fastened, which extends close to the inner wall of the housing 18 of the comminution device 19 and adjoins the upper edge 29 of a lateral connecting piece 30 for the suction line 31, around the waste water after passing the cutting head 22 to reject the connection piece 30.
  • a partition 33 is fastened above this deflector plate 28 on the end housing part 16.
  • the eccentric screw pump 35 is fastened to the upper end-side housing part 15.
  • the suction port 36 of this pump to which the suction line 31 leading to the comminution device 19 is connected, is located laterally on a housing part 39 which encloses a coupling rod 38 and on which the stator housing 40 of the eccentric screw pump 35 adjoins in the axial direction.
  • the coupling rod 38 via two watertight encapsulated ball joints 41, 42 represents the connection between the shaft end 7 of the electric motor 3 and the helically wound pump rotor 44, which is only shown in half in the drawing.
