Definitions

  • the inner part of the stationary crushing element is preferably provided with a plurality of teeth. These teeth preferably protrude into the suction mouth and have cutting edges. Upon rotation of the rotating element of the comminution device, these cutting edges contribute to a comminution of the solid admixtures in the pumped medium. It proves to be particularly advantageous if the peripheral element of the comminution device has openings for flowing in the medium to the impeller. Preferably, these are radial openings.
  • the peripheral part is enclosed by the fixed part attached to the suction-side housing, which is provided with a plurality of teeth. The teeth are located in the area swept by the openings of the rotating part.
  • FIG. 1 shows an exploded view of a wastewater lifting plant with a centrifugal pump, which has a comminution arrangement
  • FIG. 2 shows a section through a stationary element of the comminuting arrangement illustrated in FIG. 1,
  • the container 1 is provided on its upper side with a hand hole which is closed by a cover 4.
  • a sensor for detecting the level is arranged.
  • a float switch is used.
  • the container 1 has a vent connection 5.
  • a housing part 6 of the centrifugal pump is positively integrated.
  • the housing part 6 in the exemplary embodiment is a spiral housing of the centrifugal pump. It consists of a cast material.
  • the housing part 6 is enclosed in a form-fitting manner by walls 7 of the container 1 made of plastic.
  • the walls 7, which enclose the housing part 6, are integrally formed with the rest of the container 1.
  • the housing part 6 is embedded in the container 1. In the exemplary embodiment, this is achieved by rotational sintering. In this method, the following steps are carried out: - fixing the housing part 6 in a rotational mold,
