Definitions

  • the invention relates to a cleaning device for biotechnological and process engineering containers, with a spray device for spraying the inside of containers and a supply line connected to the spray device for at least one liquid or gaseous cleaning medium.
  • the known cleaning devices of this type have a feed line protruding through the container wall into the interior of the container with a spray ball arranged at the end of the spray ball or a rotating nozzle device at a considerable distance from the container wall, a shut-off device being located in the feed line outside the container.
  • these devices are not suitable for containers which are largely filled with liquid medium during the actual course of the process, since on the one hand the spray devices which permanently protrude into the interior thereof and which stand still during the actual process are wetted on the outside by the liquid medium, medium splashes and foam and, on the other hand, the liquid medium also penetrate into the spraying device and the feed line can, which causes difficult to remove dirt, incrustations and blockages.
  • such containers can be designed such that they are completely filled with cleaning liquid for cleaning, which is circulated by built-in stirring devices until the inner surfaces of the container are sufficiently cleaned.
  • cleaning liquid for cleaning which is circulated by built-in stirring devices until the inner surfaces of the container are sufficiently cleaned.
  • this procedure is quite time-consuming and also requires the use of large amounts of cleaning liquid, especially since the container usually has to be filled with cleaning liquid several times.
  • the object of the invention is now to provide a cleaning device of the type mentioned, which enables simple and quick cleaning of the inner surfaces in the container without excessive cleaning agent consumption and is also suitable for containers in which sensitive biotechnological processes are carried out or toxic or from dangerous substances are implemented for other reasons.
  • the cleaning device of the type mentioned is equipped according to the invention with the features of claim 1.
  • a container can be cleaned quickly and effectively with relatively small amounts of cleaning medium without having to open it between the actual production phase and the cleaning phase. Since the end wall of the spray cylinder can be aligned with the inner wall of the container in its rest position, there are no disruptive influences on the flow conditions in the container filling, so that there are neither dead zones nor foam formation. Since the spray cylinder reliably seals against the surrounding container wall in its retracted rest position, the liquid contained in the container during the actual process cannot penetrate into the spray cylinder or its feed line and, conversely, no cleaning medium can escape into the container. By appropriate selection of the number and the angular direction of the spray nozzles, the cleaning device can be designed without difficulty so that the inner surfaces of the container can be cleaned effectively with relatively small amounts of cleaning medium.
  • the spray cylinder which can advantageously be displaceably guided in a sealing housing to be installed in the container wall, can be moved between its rest position and its cleaning position either by axial displacement and / or twisting by hand or expediently by means of a preferably pressure-actuated servomotor.
  • a preferably pressure-actuated servomotor can be provided.
  • optimal attachment locations can be selected with regard to the desired cleaning, so that the areas particularly prone to contamination and incrustation, that come into contact with foam or additives introduced through the inlet openings during the normal course of the procedure can be cleaned thoroughly.
  • the cleaning device shown in the figures has a guide housing 2 built into the container wall 1a of a container 1 with an annular seal 3 sealing against the container wall 1a.
  • a hollow spray cylinder 7 with a flat, closed end wall 7a, a cylindrical peripheral wall 7b and one A large number of spray nozzles 8 arranged in the peripheral wall 7b are both axially displaceable and rotatable about its longitudinal axis.
  • an annular seal 5 is arranged close to the end wall 7a, which reliably prevents the passage of liquid or cleaning medium in the rest position of the spray cylinder.
  • the spray cylinder 7 has at its end remote from the container a transverse wall 9 which is connected via an actuating rod 13 to a piston, not shown, which is sealingly displaceably guided in a pneumatic actuating cylinder 16, which is only indicated schematically.
  • the actuating rod 13 is guided through a central opening in the rear wall of the guide housing 2 provided with ring seals 14 and 15.
  • the interior of the spray cylinder 7 is connected via through openings 10 in the transverse wall 9 to a housing chamber 12 in the guide housing 2, which has a connection opening 11 for a feed line 22.
  • An annular seal 4 is also arranged between the rear wall and the main part of the guide housing.
  • a further ring seal 6 is arranged at the point which, in the cleaning position of the spray cylinder 7 shown in dashed lines in FIG. 2, lies tightly adjacent to the inner surface of the container wall 1a against the peripheral wall of the guide housing 2 which guides the spray cylinder 7.
  • spray nozzles 8 are provided at predetermined circumferential distances at different angles, which are matched to the shape and dimensions of the container 1 to be cleaned, so that the inner surfaces of the container 1 in the extended cleaning position of the spray cylinder 7 shown in broken lines can be completely sprayed with cleaning medium and rotated when rotated about its longitudinal axis.
  • the actuating cylinder 16 is connected to a compressed air line 20 via connecting lines 17 and 18 and a changeover valve 19, so that a piston which is displaceably displaceable in the actuating cylinder 16 and is connected to the actuating rod 13 is axially displaced by actuating the changeover valve 19 can, whereby the spray cylinder 7 can be axially displaced between the rest position shown in FIG. 2 and the cleaning position indicated in dashed lines.
  • a rotary device 21 On the side of the actuating cylinder 16 facing away from the container 1, a rotary device 21 is also attached, which in the embodiment shown has a turbine wheel, not shown, which is arranged in a housing and which is connected to the actuating rod 13, which penetrates the actuating piston 16, for common rotation and by Compressed air is rotated, which flows from the chamber of the actuating cylinder 16 facing away from the container 1 via a through bore of the actuating rod 13 only released in the cleaning position of the spray cylinder 7 into the housing of the rotating device 21 and, by rotating the turbine wheel, simultaneously the spray cylinder 7 about its longitudinal axis rotated until the changeover valve 19 is reversed.
  • the axial displacement and rotation of the spray cylinder 7 is brought about by the compressed air supplied via the compressed air line 20, without other drive sources being required.
  • the rotary device can of course also be designed as a separately driven servomotor or the actuating rod 13 can be guided by helical engagement devices in such a way that they inevitably move simultaneously in their axial displacement is rotated about its longitudinal axis.
  • the feed line 22 is connected to supply lines for steam, alkali, acid and water via separate shut-off valves 23, 24, 25.
  • the switching valve 19 and the shut-off valves 23 to 26 are actuated via a conventional control device, not shown, according to a predetermined switching program so that the container 1 after draining the liquid product contained therein during the actual process sequence by corresponding actuation of the switching valve 19 and the shut-off valves 23 to 26 one after the other, for example first with lye, then with water and finally with steam. How many different and which cleaning media are used depends, of course, on the type of products processed in container 1.
  • the cleaning device explained above on the basis of a preferred exemplary embodiment can be modified appropriately by the person skilled in the art in various ways depending on the requirements of the individual case, provided that at least one spray cylinder which can only be extended from the container wall 1 a with a closed end wall and spray nozzles arranged in the peripheral wall is used for cleaning.
