  • This may be, for example, a compressor and / or a pressurized storage.
  • Fig. 14 is that out Fig. 13 known and described purely by way of example swirling device 70 disposed in a treatment tank 4 and thereby exemplifies the inventive device.
  • the treatment container 4 is bounded in this case in the longitudinal direction on the one hand by the Wehrwandung 12 and on the other hand by the rear wall 92.
  • In the width direction of the treatment vessel is bounded on the one hand by the first side wall 90 and on the other hand by the second side wall 91.
  • the bottom 82 of the treatment container 4 preferably has a drain outlet 85, through which the treatment substance from the main receiving space can be discharged, in particular derivable or pumpable.
  • the drain outlet 85 is preferably connected to the filter device 18 in such a way that the treatment substance discharged via the drainage orifice 85 is fed to the filter device or can be supplied.
  • the weir wall 12 delimits the collecting space 14 into which the impurities swirled up by the swirling device 70 can be guided, with the treatment substance passing over the weir wall 12, over the drain outlet 83 to the filter device 18 for filtering.
  • pipes in particular made of stainless steel, with a preferred diameter of between 4 mm and 6 mm, are preferably permanently installed on the tank bottom of the treatment plant. These tubes are preferably combined via a distributor unit.
  • each tube is provided with a shut-off valve, wherein it is alternatively conceivable that only the distributor unit is provided with a valve device, in particular a shut-off valve, such as a magnetic shut-off valve, so that individual partial areas or the entire area can be acted upon in the bath. That is, as needed, the fluidizing fluid can be selectively supplied to one or more tubes, whereby special flows or turbulences can be generated in the treatment substance.
  • the fluidizing fluid under pressure, in particular compressed air, embedded in the bath or the treatment substance and thus the still stored on the ground dirt whirled, so that he in can distribute the liquid or the treatment substance.
  • the admission, in particular blowing, of the fluidizing fluid, in particular of the compressed air, is preferably controlled by a time-switching valve and / or a control device 86 and can take place uniformly or pulsatingly, permanently or at programmed time intervals or as a function of detected sensor measurement data.
  • the filter device 18 or the installed filter system preferably runs with and removes the fluidized up dirt from the treatment substance.
  • Fig. 15 schematically shows the ascending fluidizing fluid, in particular the rising air bubbles 88.
  • the treatment substance is swirled.
  • impurities, in particular sludge are stirred up with the air bubbles out of the bottom region of the device according to the invention and conveyed upwards to the weir flow.
  • a line 75 may in this case be coupled to the treatment vessel 4 such that portions of the treatment substance can be removed from the treatment vessel 4.
  • the treatment substance fractions removed by means of the line 75 are then preferably supplied to the swirling device 70 by means of a pumping device (not shown).
  • the swirling fluid delivered by the swirling device 70 in this case to the treatment substance provided in the treatment container for swirling the treatment substance provided in the treatment container is thus the proportion of the treatment substance removed via the line 75.
  • the line 75 may in this case be connected, for example, to the treatment substance removal means or the opening or mouth or suction opening 85.
  • FIGS. 13-15 described vortexing device 70 is of course used in a similar or identical or adapted manner in a designed for the treatment of wire or wire coils treatment device 1 or providable.
  • FIGS. 13-15 thus described objects also in accordance with the FIG. 3 can be implemented.
  • the treatment baths 42 shown correspond to a treatment tank 2, respectively.
  • the ultrasonic equipment 11 can likewise be used in all treatment devices 1 shown.
  • Fig. 16 shows a purely exemplary and schematic structure of the treatment plant 100 according to the invention.
  • one or more deforming means, particularly for drawing, of the treatment article 2 previously treated by the treatment device 1 may be further treated without having to adversely affect the corrosion resistance.
  • a drying device (not shown) is provided or designed for drying the treatment object 2.
  • Fig. 17 shows a representation of a surface finish of an inventively treated wire or wire part polished in a longitudinal section.
