1. A distribution device for a slurry comprising liquid and solid constituents, comprising:
a housing with an inlet for the slurry, an end wall at a driving side, an opposite further end wall and a plurality of outlets at one or both of the two end walls for distributing the slurry,
a rotor, which is arranged in the housing and rotatable about a rotation axis, with
at least one blade arrangement for sweeping over the outlets at the inside of the housing, and
an air distribution chamber for distributing compressed air to the at least one blade arrangement,
a driving unit with a motor, which is arranged outside the housing, and a drive shaft, which is coaxial with the rotation axis, passes through the end wall at the driving side and is connected to the rotor in a rotationally fixed manner, and
an annular air chamber, which passes the end wall at the driving side and is arranged coaxially with the rotation axis and radially outside the drive shaft, wherein the annular air chamber is connected to an air inlet for compressed air at the outside of the housing and to the air distribution chamber at the inside of the housing in an air-conducting manner, and wherein the annular air chamber is entirely outside the drive shaft.
