  • tank systems e.g. storage tank systems
  • the storage of explosive and / or corrosive liquids in storage tank systems and the filling of these liquids in application-oriented smaller containers or templates, e.g. B. drums, canisters, dosing templates etc., must be carried out properly and professionally and enable safe handling.
  • the design and handling of a storage tank system and the delivery and / or metering system used for filling the explosive and / or corrosive liquids must therefore meet certain requirements.
  • the storage tank system and the delivery and / or metering system combined with it must be capable of being operated in an explosion-proof manner and all parts of the system that come into contact with the liquid must be designed to be as wear-free and corrosion-free as possible.
  • the object of the present invention is to provide a pneumatic conveying and / or metering system for filling liquids from storage tank systems, which can be operated safely, as simply as possible, as wear-free as possible and not susceptible to corrosion for as long as possible without maintenance.
  • the invention proposes a pneumatic conveying and / or metering system (pump system) which is used to fill liquids, in particular explosive and / or corrosive liquids, from a storage tank (1) into smaller containers or templates.
  • the pneumatic conveying and / or dosing system according to the invention is characterized in claim 1 and preferred configurations result from the subclaims.

  • pneumatic delivery and / or metering system in storage tank systems creates a system for storing and filling, in particular, explosive and / or corrosive liquids, the construction of which is uncomplicated and easy to maintain and which ensures safe and professional storage during operation and filling of liquids permitted, special handling measures must be observed for their handling.
  • the pneumatic conveying and / or dosing system for storage tank systems can be adapted to the respective explosive or corrosive liquids.
  • the pump system used or combined in the storage tank system is maintenance-friendly and long-term resistant, since there are essentially no moving parts, with the exception of a few safety, non-return or Float valves that come into contact with the explosive and / or corrosive liquid and that all other, possibly critical, system parts can be arranged outside the tank container in a safe and user-friendly manner.
  • the pump system manages with a minimum of moving parts and has the further advantage that no electrical installations come into contact with the aggressive liquid to be stored or filled.
  • the control of the filling quantity and a uniform conveying and / or metering of the liquid to be filled can be achieved by control systems (4) which are known per se and which can operate both analog and digital.
  • Such control systems can be, for example, time relays, flow meters or pneumatic-electrical control units.
  • a pressure source (3) conventional piston pumps, for. B. a "suction piston pump", or pressure gas systems are used, which are controlled by the control system (4).
  • the pressure source (3) only acts alternatively as a suction source, and only with certain pressure sources (3) such as. B. a "suction piston pump”. If, in a variant of the invention, the pump system is operated with a suction piston pump of this type, this acts on the liquid to be conveyed or dosed by alternating suction and pressure forces, the liquid intake cylinder (2) and the pressure and suction source (3) a compressed gas, in particular an inert gas described below, circulates. Due to the alternating suction and pressure effect, the liquid intake cylinder (2) is filled alternately via the suction line (7) during operation of the pump system and then emptied via the delivery line (9) and the removal or filling device (11).
  • the pump system is operated with a compressed gas system as the pressure source (3)
  • the variant of the invention according to FIG Fig. 1 the suction.
  • the liquid absorption cylinder (2) is therefore alternately emptied and filled via an alternating pressure build-up and pressure equalization in the tank system, for example with solenoid valves in the pressure source (3) controlled via the control system (4). Due to the gas pressure in the liquid absorption cylinder (2) built up via the pressure source (3), it is emptied (after a previous filling process) alternately via the delivery line (9) and the removal and filling device (11) and then refilled via the suction line (7) .
  • the filling process of the liquid receiving cylinder (2) is effected by the hydrostatic pressure of the explosive and / or corrosive liquid contained in the tank system.
  • the control system (4) preferably ensures fully automatic operation of the pump system in the tank system when the liquids are being filled; all other valves, shut-off devices and the amount of liquid to be withdrawn can also be controlled by means of appropriate liquid flow meters in connection with the removal or filling device (11).
  • this is characterized in that all parts of the system which come into contact with the liquid - that is to say the pump system according to the invention and the tank system operated therewith - are designed to be corrosion-resistant, preferably using aluminum or a corrosion-resistant stainless steel or plastic are.
  • Stainless steel types 1.4571 or 1.4306 are examples of corrosion-resistant stainless steels. These types of stainless steel are particularly recommended for hydrogen peroxide tank systems and are very suitable for concentrations of around 60 to 70% by weight.
  • PE is particularly suitable for hydrogen peroxide concentrations of up to 50% by weight; at low concentrations of up to about 35% by weight of hydrogen peroxide, rigid PVC can also be used without any problems.
  • aluminum is recommended as the material which is used exclusively at concentrations above 70 to 85% by weight.
  • the liquid absorption cylinder (2) is formed inside the tank container (1) and preferably has a geometry that is matched to the delivery and / or metering performance. As appropriate geometrical dimensions of the liquid absorption cylinder (2), it can have a length of 0.5 to 3 m and a radius of the base area of 7.5 to 50 cm.
