A storage vessel (1) for liquid substances which are supplied to a consumer is provided with a device for cleaning the connecting pieces (7, 8, 13, 18) when the storage vessel (1) is changed, the storage vessel (1) having a connecting piece (13) provided with a shut-off device (15) and a coupling (16) for connection to a connecting piece (7) provided with a coupling (10) to a pressure gas line (3) with a shut-off device (5), and a connecting piece (18) provided with a shut-off device (19) and a coupling (21) for connecting a discharge line (17) in the storage vessel (1) to a connecting piece (8) provided with a coupling (11) and a shut-off device (6) for supplying the substance subjected to the pressure gas in the vessel (1) to the consumer. A solvent vessel (23) for flushing the connecting pieces (7, 8, 13, 18), a vessel (28) for spent solvent which is evacuated in order to suck solvent into the connecting pieces (7, 8, 13, 18) as a vacuum source form a package (30) with the storage vessel (1).
A storage vessel for liquid substances which are supplied to a consumer, having a device for cleaning the connecting pieces when the storage vessel is changed, the storage vessel having a connecting piece provided with a shut-off device and a coupling for connection to a connecting piece provided with a coupling to a pressure gas line with a shut-off device, and a connecting piece provided with a shut-off device and a coupling for connecting a discharge line in the storage vessel to a connecting piece provided with a coupling and a shut-off device for supplying the substance subjected to pressure gas in the vessel to the consumer, a solvent vessel for flushing the connecting pieces, a vessel for spent solvent and a vacuum source for sucking solvent into the connecting pieces being provided, wherein the solvent vessel (23) and/or an evacuated vessel (27) forming the vacuum source form a package (30) with the storage vessel (1).
A storage vessel according to any of the above claims, wherein the solvent vessel (23), the evacuated vessel (27) and/or the vessel for spent solvent are adapted to be connected via a shut-off device (25, 26) to the connecting piece (13) to the pressure gas line (3) and to the connecting piece (18) to the discharge line (17).
A storage vessel according to any of the above claims, wherein the connecting piece (13) to the pressure gas line (3) and the connecting piece (18) to the discharge line (17) are connected via a connecting line (22) with a shut-off device (20).
A storage vessel according to any of the above claims, wherein the shut-off devices (15, 19) in the connecting pieces (13, 18) to the pressure gas line (3) and the discharge line (17) and/or the shut-off devices (25, 26) connecting the solvent vessel (23), the evacuated vessel (27) and/or vessel for spent solvent to the connecting pieces (13) and (18) to the pressure gas line (3) and the discharge line (17) are provided on a plate (41) having channels for connecting the connecting pieces (13, 18) to the interior of the storage vessel (1) and the discharge line (17) and/or the connecting line (22).
A storage vessel according to any of the above claims, wherein the shut-off devices (15, 19) in the connecting pieces (13, 18) to the pressure gas line (3) and the discharge line (17) and/or the shut-off devices (25, 26) connecting the solvent vessel (23), the evacuated vessel (27) and/or the vessel for spent solvent to the connecting pieces (13, 18), and/or the shut-off device (20) in the connecting line (22) are formed so as to be automatically operable via control lines (31 to 34).
A storage vessel according to any of the above claims, wherein it is disposed in the interior of a barrel, and the space between the storage vessel (1) and the circumferential wall (45) of the barrel forms the vessel (27) for spent solvent.
