Definitions

  • the invention relates to a transport container made of corrosion-resistant steel for high-purity liquids, with a screw or flange closure in an upper container wall and with at least two connecting pieces protruding from the screw or flange closure, at least one of which is connected to an immersion tube reaching to the bottom of the container.
  • Transport containers made of corrosion-resistant steel can be designed for higher mechanical stress than pressure containers; however, the immersion tubes required for the removal of the liquid and a level measurement present constructive difficulties.
  • German patent application P 36 36 888 which does not belong to the pre-published prior art, to attach the connecting piece of an immersion tube outside the screw closure in the upper container wall and to weld the lower end of the immersion tube to the container bottom via a web.
  • the aim is to keep the screw or flange closure as small as possible to execute, ie the closure opening should not be larger than is required for use as an inspection and cleaning opening.
  • the object of the invention is therefore to design a transport container of the type mentioned in such a way that, despite the small closure diameter, the connection piece protruding from the top plate does not interfere with one another, even with the pipe connections attached to it.
  • connecting pieces are angled upwards and outwards. This enables on the one hand to arrange the through holes through the head plate close together, so that the head plate and thus the screw or flange closure can be made with the smallest possible diameter; on the other hand, there is sufficient space around each connection piece to accommodate the respective connection fitting.
  • the immersion tube or possibly several immersion tubes are only attached to the common head plate and can thus be assembled and disassembled in a simple manner, it is not necessary in the manufacture of the transport container to carry out assembly or welding work inside the container, so that there is also no need for this Make the opening for the screw or flange closure larger than is necessary for inspection and cleaning purposes.
  • the cleaning of the container interior is facilitated by the fact that after the head plate has been removed, there are no built-in parts in the container interior. This fact also means that the closure opening can be chosen to be small.
  • the angled upward and outward angling of the connecting piece can be above, below or within the head plate.
  • dip tubes can be connected to one another in their lower region by at least one welded-on web. This significantly increases the rigidity of the interconnected dip tubes so that undesired deformations of the dip tubes, for example due to lateral forces exerted by the liquid, are avoided even with relatively thin or thin-walled dip tubes.
  • the dip tube has at its lower end a plastic sleeve projecting downward beyond the end of the metallic dip tube.
  • a plastic sleeve projecting downward beyond the end of the metallic dip tube.
  • Fig. 1 shows a vertical section of a transport container for high-purity liquids, such as are required in the manufacture of semiconductor components.
  • the transport container 1 made of corrosion-resistant steel by welding has a cylindrical wall section 2 which is connected to an upper container wall 3 and a container bottom 4 is connected, which are designed in a conventional manner as bobbin bottoms.
  • a screw cap 5 is arranged centrally in the upper container wall 3 and can be opened for inspection and cleaning purposes.
  • an immersion tube 6 For filling and emptying the transport container 1, an immersion tube 6 is provided, which has a connecting piece 7 at its upper end.
  • a second vertical immersion tube 8 is arranged parallel to the immersion tube 6, which serves to measure the fill level and also carries a connecting piece 9 at its upper end.
  • the two connecting pieces 7 and 9 of the dip tubes 6, 8 are carried out upwards through a common head plate 10 and angled upwards and outwards.
  • the head plate 10 forms a removable insert of the screw cap 5 and is held on it by a union nut 11.
  • a third connection piece 12 which can run straight or also obliquely from the head plate 10 and is passed through it, serves to connect a gas line in order to press out the liquid contained in the transport container 1 through the dip tube 6 serving for removal and the connection piece 7.
  • the screw cap 11 is arranged under a protective cap 13 which is removably attached to the upper container wall 3 and which is surrounded by a protective collar 14 which is provided with openings and which is welded to the upper container wall 3.
  • the two dip tubes 6 and 8 are connected to one another by a welded-on web 15.
  • the two immersion tubes 6 and 8 each have a plastic sleeve 16 and 17 at their lower end (FIG. 2).
  • Each plastic sleeve 16 or 17 protrudes downward beyond the end of the metallic dip tube 6 or 8 and has a stepped bore 18 or 19, the bore shoulder 20 or 21 of which rests on the lower end of the dip tube 6 or 8 on the end face.
  • the plastic sleeves 16, 17 can be pressed, shrunk or screwed onto the immersion tubes 6 or 8, for example.
  • the plastic sleeves 16, 17 prevent metallic contact of the immersion tubes 6, 8 with the container bottom 4 even in the event of extreme impacts which can occur in exceptional cases during transport.
  • plastic sleeves 16, 17 prevent the dip tubes 6, 8 from colliding.
  • the plastic sleeves 16, 17 consist of fluorinated, inert materials, so that a chemical reaction with the liquid is excluded.
  • connection piece 7, 9 takes place above the head plate 10
  • the bend of the connection piece 7, 9 can also lie below the head plate 10.
  • the angling can also take place in the section that lies within the head plate 10. All connecting pieces 7, 9 and 12 are designed differently in order to rule out any possibility of confusion.
  • the head plate 10 is shown in FIGS. 1 and 2 as an insert plate for the screw closure 5 shown in FIG. 1. Deviating from this, it is indicated in Fig. 3 that the head plate 10 'can be designed as a flange plate for a flange closure.
  • dip tubes 6, 8 are inserted after the completion of the transport container 1 through the upper connection opening and are not connected to the container bottom. This significantly simplifies the manufacture of the transport container 1; in addition, there are no internals in the interior of the transport container that could interfere with cleaning and inspection.
