NOVELTY - The container for circulating organic raw material such as slurry or producing biogas, comprises: a drive unit together with a rotor (10); flow ring/-tube (7) for circulating the organic raw material in a ring channel system (5) of the container; and a bulkhead wall (9) filling a cross-section (8) of the ring canal system by an opening adjustable in its vertical position within the container, where the bulkhead wall comprises a breakthrough extending itself over a part of a height of the bulkhead wall, and an upper and lower bulkhead curtains are provided to a depth of the container.    USE - The container is useful for circulating organic raw material such as slurry or producing biogas.    ADVANTAGE - The container is capable of economically circulating the organic raw material in an efficient manner.    DETAILED DESCRIPTION - The container for circulating organic raw material such as slurry or producing biogas, comprises: a drive unit together with a rotor (10); flow ring/-tube (7) for circulating the organic raw material in a ring channel system (5) of the container; and a bulkhead wall (9) filling a cross-section (8) of the ring canal system by an opening adjustable in its vertical position within the container, where the bulkhead wall comprises a breakthrough extending itself over a part of a height of the bulkhead wall, and an upper and lower bulkhead curtains are provided to a depth of the container. The upper and lower bulkhead curtains cover upper and lower sections of the breakthrough, and form itself between the openings. The bulkhead curtains: are formed as flexible elements, which are variable in its length; and are guided in vertically passing rail elements. An lower end region facing away from the opening of the lower bulkhead curtain is fixed by a holding device in the lower end region of the breakthrough or in the lower end region of the bulkhead wall in an operating position, where the holding device is voidable by an area located outside of the container in operable manner, and the fixing position of the lower end region of the lower bulkhead curtain is repealable. The holding device has two rod elements, which are arranged from an upper end region to the lower end region of the breakthrough of the bulkhead wall or the bulkhead wall passing laterally at the end region of the breakthrough whose lower end region is hinged at the lower end region of the lower bulkhead curtain. The upper end region of the rod elements is fixed into the upper end region of the breakthrough or the bulkhead wall, where the lower end region of the lower bulkhead curtain is fixed in its operating position by a fixation of the upper end region of the rod elements. The bulkhead curtain passes horizontally in which the rail elements guided crossbar is divided in foldable or collapsible segments, where a linkage of the lower end region of the holding device is performed at the lower end region of the lower bulkhead curtain over the crossbar into the lower end region. A container cover of the container has a service-cover, which is placed above the bulkhead wall and the drive unit having an implementation leading in an interior of the container for a rope of a rope winch mounted directly or indirectly to the drive unit, where the rope winch is arranged at a crane bridge passing over the service-cover. Both service-cover and the implementation are performed in a gas-tight manner.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of a container for circulating organic raw material.
