Definitions

  • the invention relates to a housing wall for a device for comminuting solids present in a substrate, in particular for ultrafine comminution of solids present in a biogas substrate, wherein the housing wall is hollow cylindrical and radially projecting in the comminution operating state of the device from a rotatable about the longitudinal axis of the housing wall rotatable shaft arranged comminution organs of the device radially surrounds.
  • the invention further relates to a device for comminuting solids present in a substrate, in particular for micronizing solids present in a biogas substrate, comprising a hollow cylindrical housing wall and a comminution device, wherein the comminution device comprises a drivable shaft which is rotatable about the longitudinal axis of the housing wall can be arranged and the at least two substantially in at least one perpendicular to the longitudinal extent of the housing wall arranged plane radially projecting from the shaft crushing members, wherein the comminution organs are surrounded in the comminution operating state of the device radially from the housing wall.
  • the object of the invention is to improve the efficiency of the comminution of solids present in, in particular, aqueous, substrates.
  • the comminuting elements arranged on the shaft are likewise rotated about the longitudinal axis of the housing wall.
  • Solids in the substrate coming in contact with the comminution devices are forced towards the housing wall due to the centrifugal forces generated by the rotation, and the larger the solids are, the stronger. There these solids meet the guide profile.
  • Subsequent solids urge the foregoing solids against the inside of the housing wall and against at least one guide surface of the guide profile. This positively forces the foregoing solids to move from the denser portion of the substrate, where there are less solids, toward a less dense portion of the substrate, which still contains a greater amount of solids.
  • the solids are then entrained by further moving in the direction of the comminution substrate and forced again to the comminution organs. There, the solids are subjected to a further comminution step. The solids pass through this cycle until the solids in the substrate have a desired size and can no longer be forcibly guided over the inside of the housing wall and the guide profile arranged there. It can be realized very accurately with the housing wall according to the invention a desired crushing result, which makes in particular a corresponding Feinstzerklein réelle of solids possible.

  • the guide profile with respect to the direction of rotation of the shaft on a positive slope.
  • the above-described effect of the housing wall according to the invention is further improved, since the rotation of the shaft and the comminution devices arranged thereon also move the substrate, and thereby the solids contained therein, at least slightly in the direction of rotation of the shaft and thus move along a guide surface of the guiding profile.
