Definitions

  • the subject matter of the present invention relates to a chemical transport container for liquid chemicals, in particular liquid high-purity chemicals for the electronics industry.
  • high-purity chemicals are understood to be chemicals which contain a maximum of 50 particles / ml with a size of> 0.2 ⁇ m and a maximum of 10 particles / ml with a size of> 0.5 ⁇ m.
  • metals such as aluminum, cobalt, chromium, copper, iron, magnesium, manganese, nickel, lead, etc. are contained in a maximum amount of 1 ppb each.
  • the maximum chloride content is 0.1 ppm, nitrate 0.2 ppm, phosphate 0.02 ppm and sulfate 0.1 ppm.
  • a large chemical container that meets all of the above requirements is not known.
  • the present invention provides a large chemical transport container that meets these requirements.
  • the transport container for liquid chemicals in particular liquid high-purity chemicals for the electronics industry of the present invention, is characterized in that it consists of an inner shell of high-purity, non-auxiliary polyethylene and an outer shell of commercially available, auxiliary polyethylene.
  • high-purity polyethylene containing no auxiliaries is understood to mean polyethylene which has been produced without any use of the normally customary auxiliaries.
  • Normally customary auxiliaries are stabilizers, in particular antioxidant ions, which are known to the person skilled in the art (see, for example, plastics 78 (2), 142 (1988)).
  • polyethylene containing auxiliary means that it is produced using the said auxiliary.
  • the space between the inner and outer shell is advantageously filled with a gas that can be metered through a valve in the outer shell.
  • gases examples are nitrogen, noble gases such as helium, neon or argon, or air.
  • the inner shell is expediently produced in such a way that it forms the smoothest possible, seamless and seamless inner surface.
  • the upper and lower part can be formed, for example, from deep-drawn bobbin-case bottoms, which in turn are made from plates, which are connected seamlessly to a cylindrical middle piece. This inner shell is completely and seamlessly encased with the outer shell.
  • the opening of the container according to the invention is closed with a closure, e.g. a closure plate, but preferably closed with a welded block flange.
  • a closure e.g. a closure plate
  • the flange like the outer shell, advantageously consists of auxiliary material-containing polyethylene and is welded on the inside, which is in contact with chemicals, to a plate made of high-purity, non-auxiliary material-containing polyethylene.
  • the block flange connects the inner and the outer shell by welding.
  • the flange has several connections for the supply and discharge lines, riser or immersion pipes and the like, which allow the container to be filled and emptied.
  • the connections for the inlets and outlets of the liquid chemical, the connections for the inlets and outlets of the inert and / or compressed gases and the like can be designed as connecting pieces, which in turn have suitable closures, such as screw closures, quick couplings, taps and / or valves can be closed are.
  • Connections for sensors and the sensors for monitoring the filling or emptying process can also be arranged in the actual container closure.
  • connections arranged in the closure serve both to fill the container and to remove the chemicals from the container.
  • the necessary feed and discharge lines for the chemical as well as any feed and discharge lines for the inert or compressed gases mentioned or the sensors or the like required for the filling or removal process are transferred to the in both when filling and when removing the chemical existing connections connected to the lock.
  • the connections e.g. In their design, e.g. in their diameter, they should all be the same. However, one or more connections or connecting pieces can deviate from this same configuration. All connection pieces can also be designed differently.
  • the inner container can be emptied by overpressure or pumping.
  • Several connections are connected to several ascending pipes made of high-purity, no auxiliary materials, reaching to the bottom of the inner shell.
  • the ventilation is expediently carried out via a membrane valve or needle valve.
  • the ventilation via the valve prevents the uncontrolled escape of chemicals through one of the riser pipe connections if a chemical-specific container overpressure has built up.
  • particle-free, filtered gas can be supplied for pressure equalization in the case of negative pressure.
  • this is in an outer container made of polyethylene tube adjusted and fixed by struts.
  • the tube is closed by a flat underbody and preferably mounted on a plastic pallet.
  • the upper side is closed by a convex upper floor with openings for the flange by welding, an elevated collar having the function of a protective collar for the fittings mounted on the container flange. It is advisable to install an outward drainage, eg a pipe, at the lowest point of the convex top floor.
  • the upper edge of the outer container can finally be closed with an additional plate.
  • the space between the outer and the inner container can be empty or completely or partially filled with a material, for example a heat-insulating material.
  • Foam plastics can have open or closed cells and are known from thermoplastic, elastomeric or thermoset polymers.
  • the foam plastic can consist of polystyrene, polyvinyl chloride, polyethylene, urea-formaldehyde resin, epoxy resin, polyimide, but in particular of polyurethane, for example based on methyl bisphenyl isocyanate.
  • the space between the outer and inner container is preferably foamed with a so-called polyurethane integral foam.
  • the chemical transport container according to the invention enables the safe transport of highly pure liquid, possibly also aggressive chemicals, even with contents of 500 l and more, without risk of contamination and risk of breakage. There will also be major temperature fluctuations avoided during transport and storage.
  • the inner shell is denoted by 1 and the outer shell by 2.
  • a gas can be metered into the space 3 between the inner and outer shell via the valve 4.
  • the block flange 5 connects the inner and outer shell by welding and has a plurality of connections (not shown in the figure) for the supply and discharge lines, riser or immersion pipes and the like.
  • the inner container is set in an outer container made of polyethylene tube 6 and fixed by struts 7.
  • the tube is closed by a flat underbody 8 and mounted on a pallet 9.
  • the top is closed with a convex top 10 with an opening for the flange 5.
  • a drainage 11 leads from the lowest point of the convex top floor 10 to the outside.
  • the outer container 6 is closed at the top by an additional plate 12.
  • the space 13 between the outer and the inner container is foamed in the lower part with a foam 14.
