  • the centrifuge drum 9 ' is rotatably mounted in the decanter centrifuge via bearing elements 11'.
  • the co-rotating conveying element 10' is also rotatably supported via bearing elements 11 '.
  • the conveying element 10 ' is designed as a helical hollow shaft and extends at least partially over the length of the centrifuge drum 9'.
  • the starting product is introduced into the hollow shaft in the form of a suspension via a feed pipe 12 'of the decanter centrifuge and delivered to the centrifuge drum 9' via openings on the circumferential surface of the hollow shaft in a filling zone 13 'and centrifuged out.
  • the centrifuge drum 9 ' has a closed outer surface on which the solid fraction in the centrifugal field is deposited to form a cake, which is conveyed in the axial direction by the helical conveying element 10 'and ejected via an outlet device.
  • a known inlet device 1' is arranged in the hollow shaft.
  • the known inlet device 1 ' comprises an inlet opening 2' through which the starting product is introduced into the inlet device 1 '.

  • the corresponding inlet devices here comprise inlet openings for introducing the starting product into the inlet device, and outlet openings for feeding the starting product from the inlet device into the filling zone.
  • a mixture can be introduced into the centrifuge drum through channels from the inlet device.
  • the object of the invention is to provide an inlet device for a decanter centrifuge, by means of which the starting product can be fed into the filling zone of the decanter centrifuge in an optimized way in the circumferential direction of the centrifuge drum, in particular homogeneously or evenly distributed.
  • the invention thus relates to an inlet device for feeding a starting product into a filling zone of a decanter centrifuge, comprising an inlet opening for introducing the starting product into the inlet device, at least one first outlet opening and a second outlet opening different from the first outlet opening for feeding the starting product from the inlet device into the filling zone , and a connection device via which the inlet opening is fluidly connected to the first outlet opening and the second outlet opening.
  • the connecting device comprises a first channel and a second channel different from the first channel, the first outlet opening being flow-connected to the inlet opening via the first channel and the second outlet opening being flow-connected to the inlet opening via the second channel.
  • the term "flow-connected" is to be understood as meaning that the first channel and second channel are designed such that the starting product flowing into the inlet device can be distributed at least partially to the first outlet opening and second outlet opening independently of one another.
  • the first channel and / or the second channel can extend at least partially from the first outlet opening and / or the second outlet opening to the inlet opening.

It is also possible that the first channel and / or the second channel is essentially flow-connected to the inlet opening via the respective other channel.
  • the connecting device is not formed by multiple channels but by a single channel, usually in the form of the inlet device itself, which guides the starting product from the inlet opening to the first outlet opening and the second outlet opening.
  • the starting product is not selectively directed to the first outlet opening and the second outlet opening.
  • the first channel and the second channel can have different cross-sectional geometries.
  • the cross-section of the first channel and the second channel can be n-cornered, circular or oval. It is also possible for the cross-sectional geometry of the first channel and / or of the second channel to vary over the length of the respective channel.
  • the inlet opening can run coaxially to a longitudinal axis of the inlet device.
  • the first outlet opening and / or the second outlet opening can run radially to the longitudinal axis.
  • the first channel and / or the second channel can thus be curved relative to the longitudinal axis, so that the first channel and / or the second channel essentially lead to a targeted deflection of the starting product from an axial direction into a radial direction.
  • the first outlet opening and the second outlet opening can also be arranged offset along the longitudinal axis.
  • the inlet opening, the first outlet opening and the second outlet opening are in different planes.

That is, within the scope of the invention, the inlet device can also have further channels in addition to the first channel and the second channel.
  • An essential advantage of the inlet device according to the invention is that the starting product is fed into the filling zone of the decanter centrifuge in an optimized manner in the circumferential direction of the centrifuge drum, in particular distributed homogeneously or evenly. As a result, the starting product in the filling zone is delivered evenly to the centrifuge drum and centrifuged out. As a result, the cake deposited on the inner surface of the centrifuge drum has a uniform thickness in the circumferential direction of the centrifuge drum.
  • the uniform thickness of the cake prevents an imbalance on the rotating centrifuge drum, so that additional vibrations of the centrifuge drum, which have a negative effect on the bearing of the centrifuge drum and lead to increased wear, can be avoided.
  • the starting product in the inlet device according to the invention is exposed to less turbulence, which has a positive effect on the flow losses and vibrations.
  • the first channel extends continuously from the first outlet opening to the inlet opening
  • the second channel extends continuously from the second outlet opening to the inlet opening. This results in improved conveyance of the starting product in the inlet device due to lower losses.

  • the starting product is thereby collected in the mixing chamber before it is passed into the first channel and / or the second channel. Because of this configuration of the inlet device, there is an improved homogenization of the starting product in the inlet device.
  • the cross-sectional area of the first channel increases from the inlet opening to the first outlet opening and / or the cross-sectional area of the second channel increases from the inlet opening to the second outlet opening.
  • first channel opens into the first outlet opening at a predefinable angle and / or the second channel opens into the second outlet opening at a predefinable angle, so that the first channel and / or the second channel follow a curve . This ensures that the starting product is fed into the filling zone of the decanter centrifuge.
