Definitions

  • the invention relates to a method and an apparatus for preparing liquid mixtures.
  • the invention relates in particular, but not exclusively, to the preparation of dilute solutions from a concentrated solution and a diluent, but it can of course be used wherever mixtures of miscible liquids are required.
  • treatment liquids of certain strength as precisely and as quickly as possible.
  • US Pat. No. 4,002,267 already describes a method for preparing solutions from a concentrate and a diluent, in which the concentrate is introduced into a container device / the content of this device is then emptied into a line which leads to a storage container , and at the same time a measured volume of diluent is introduced into the same line, so as to prepare the diluted solution in the storage container.
  • this requires a complicated network of pipes and a very precise measuring device for the volume of diluent.
  • no provisions have been made for thorough and sufficient mixing of the diluted liquid in the storage container.
  • the specific weights of the liquid in the two containers and in the different sections of each of them are adjusted. After further circulation of the liquid by the pump from the processing tank to the storage container, the specific weight of the liquid in each of the two vessels and in each partial area thereof becomes the same size, so that the complete mixing of the concentrated solution with the diluent has taken place.
  • FIGS. 1 to 5 are cross-sectional side views of the apparatus according to the invention, in which the same parts are designated with the same reference numbers.
  • Fig. 1 an empty apparatus is shown, which comprises a liquid storage container 1 and a processing container or tank 2 for treatment liquid.
  • Concentrated liquid is to be mixed with a diluent, in this case water, in the storage container 1 and then fed into the processing tank 2, so that a liquid of a predetermined concentration of active substances is present in the latter, while liquid of the same active substance concentration is provided in the storage container 1 can be used to refill the liquid in the processing tank 2.
  • a diluent in this case water
  • a water supply line 3 and a standpipe 4 which is open at the upper end and which is connected via a pipe 5 to the bottom of the processing tank 2.
  • a liquid level switch 7 which switches off the dilution water when the liquid level reaches a predetermined level.
  • a pipe 8 connects the bottoms of the two containers 1 and 2.
  • a pump 9 is provided which is able to pump liquid from the container 1 into the tank 2 or vice versa from the tank 2 into the container 1.
  • the two containers 1 and 2 are empty of liquids. 2 shows a certain volume of concentrated liquid C which has been poured from a previously packaged container into the storage container 1 and only reaches a level below the full height of the standpipe 4.
  • Fig. 3 it is shown how the water used for dilution D flows from the water supply line 3 and partially mixes with the concentrated liquid C, the liquid level in the reservoir 1 rising so that an excess liquid through the standpipe 4 down and over into the Processing tank 2 flows.
  • the liquid in both containers 1 and 2 is labeled C + D to indicate that the mixture of C and D therein is only an incomplete one.
  • the pump 9 is switched on and pumps liquid from the tank 2 into the container 1, excess liquid from the latter flowing back through the standpipe 4 into the tank 2, so that the level of the liquid in the tank 2 is maintained.
  • the specific gravity of the liquid in each of the two containers is then measured using the hydronic capsule 10 and hydrometer 11 until it is determined that the specific gravities of the two liquids match.
  • the pump 9 is then stopped.
  • the apparatus according to FIGS. 1 to 5 When the apparatus according to FIGS. 1 to 5 was started up, it was used, for example, to prepare a photographic fixing solution of a desired treatment concentration, and photographic copies were thus fixed in the processing tank 2.
  • the main active ingredient of the fixing solution is ammonium thiosulfate.
  • a commercially available concentrated ammonium thiosulfate solution contains 687.2 g of active ingredient per liter and had a specific weight of 1.335. The requested The concentration of ammonium thiosulfate in the treatment solution should be 137.44 g of active ingredient per liter of solution, corresponding to a specific weight of 1.076.
  • ammonium thiosulfate concentration in the two containers should now be 137.44 g / liter and thus be the same as the required concentration.
