Wet Treatment Devices, in Particular Dyeing Centrifuges, and a Method for Operating such a Dyeing Centrifuge

摘要

A wet treatment device (1) for the wet treatment of textile making-ups (T) has a treatment drum (10) which is driven about a vertical axis of rotation (A) in a direction of rotation (V) by a rotary drive, The treatment drum (10), which can be loaded at the top, has a drum shell (13) arranged on the circumferential side relative to the axis of rotation (A) and having an outlet opening (20). The latter opens into a return line device (30) which is arranged to be fixed against rotation and which has an annular channel (32) enclosing the treatment drum (10) radially and formed so as to be open in the direction of the outlet opening (20). in addition, the return line device (30) has a discharge opening (31), which is positioned above the drum base (11) and closer to the axis of rotation (A) than the first outlet opening (20). A rotating treatment drum arranged within a pressure vessel is also disclosed, as well as a method for the wet treatment of textile making-ups in a treatment drum, in which the liquor is led back into the center of the treatment from by a return line without using any drive.

主权项

1. 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 means, wherein the recirculation line means 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, and wherein the recirculation line means has an outflow opening which is positioned above the drum base and closer than the first outlet opening to the axis of rotation.
