Definitions

  • the present invention relates to macerator pumps.
  • a dilacerator pump can split fibers contained in suspension in wastewater.
  • a macerator pump which comprises a shaft driven in rotation by a motor, an impeller integral in rotation with the shaft in a pump body and means for macerating materials carried by the fluid sucked by the impeller.
  • the aim of the invention is to perfect a macerator pump of this kind by making it more efficient.
  • the pump according to the invention is defined in claim 1.
  • the angular positions of the moving toothed sectors and the fixed tooth sectors are such that not all the moving sectors overlap at the same time fixed gear sectors. In particular, it can be done so that at any one time only one movable tooth sector of all overlaps a fixed tooth sector.
  • the configuration according to claim 5 allows an adjustment of the axial position of the fixed tooth sector in order to compensate for the increase in the wear clearance of the fixed and moving sectors. This adjustment can be done by removing shims, which are initially mounted between the pump body and the fixed tooth sector.
  • the grinding pump comprises a shaft 1 driven in rotation by a motor 2 and an impeller 3 integral in rotation with the shaft 1 and housed in a pump body 4.
  • the impeller sucks up the impurity-laden liquid through a suction orifice 5 in the space between four movable toothed sectors 6 rotatably connected to the shaft 1 and at 90 ° from each other and three toothed sectors 7 at 120 ° from each other fixed screwed on the pump body 4.
  • the fibers in suspension are lacerated by the teeth in this interval.
  • Sectors 6 and 7 have stepped stair profiles that face each other and are stepped downward from shaft 1 to pump body 4 in the direction to impeller 3.
  • the movable toothed sectors 6 are closer to the impeller 3 that the sectors 7 toothed fixed.
  • Each turn of the shaft 1, a movable toothed sector 6 straddles a sector 7 stationary tooth with a clearance of 0.4 mm.
