Separation device for separating a solid material from a conveying stream and method for maintaining such a separation device

A separation device for separating a mixture of a solid material and a fluid, the separation device comprising:

• a housing that has at least one housing inlet for supplying the mixture of the solid material and the fluid and at least one housing outlet for discharging the solid material or the fluid separated from the mixture, and
• a rotor arranged within the housing and mounted rotatably around a longitudinal axis, the rotor being configured to cause movement of the solid material in the direction of the longitudinal axis by rotating,
• wherein the rotor comprises multiple rotor segments that are arranged in series with one another along the longitudinal axis, wherein the rotor segments are separable from one another,
• wherein each rotor segment has multiple transport elements, wherein the respective transport elements of adjacent rotor segments are in series along the longitudinal axis, and
• wherein each of the multiple rotor segments is configured to cause movement of the solid material in the direction of the longitudinal axis.
