Wet treatment devices, in particular dyeing centrifuges, and a method for operating such a dyeing centrifuge

A wet treatment device for the wet treatment of textile make-ups, having a treatment drum which is driven in a direction of rotation about a vertical axis of rotation by a rotary drive, wherein the treatment drum has a closed drum base, a drum opening on a top side, and a drum shell which is arranged at the circumference relative to the axis of rotation and which has at least one first outlet opening, characterized in that the first outlet opening issues into a rotationally fixedly arranged recirculation line device, wherein the recirculation line device has a ring-shaped duct which radially encompasses the treatment drum and which is formed so as to be open in the direction of the first outlet opening, wherein an opening of the ring-shaped duct that opens in the direction towards the first outlet opening of the drum shell is in the form of an encircling slot at a radially inner side of the ring-shaped duct, wherein the encircling slot opens in the direction of the drum shell and encircles the drum shell, and wherein the recirculation line device has an outflow opening which is positioned above the drum base and closer than the first outlet opening to the axis of rotation, wherein the drum shell is configured to rotate with respect to the encircling slot of the recirculation line device.
