Definitions

  • the invention relates to a device for pickling tape or wire Material, with guiding devices for the material in several lines vertical sections and devices to the material with a pickling liquid to bring in contact.
  • Such a system is known for example from AT 206 247 B1, in which a pickling tower is described that one or more vertically oriented Snakes a band or wire-shaped material and in which Pickling tower spray nozzles are provided for applying the pickling medium to the material are.
  • AT 218 331 B1 describes a similar system with its pickling tower, in which the pickling material guided vertically in loops by means of the pickling material comprehensive ring nozzle is sprayed with the pickling medium, which pickling medium then flows down the pickling material.
  • the invention provides that at least two vertical pickling cells with two vertical strands each are provided, and that the Individual cells can be switched on and off independently of one another are.
  • the vertical design leads to the smallest space requirement in the built-up area to a large maximum pickling length, with the optional switching on or off entire pickling cells an exact change in the effective length of the Influence of the pickling medium is possible, which is significantly improved Drainage of the pickling medium from the vertical pickling material is determined.
  • the individual strands optionally and can be switched on and off independently of each other. That is natural an even finer subdivision of the possible effective pickling lengths can be achieved.
  • the devices include: to bring the material into contact with a pickling liquid, including overflows for one waterfall-like overflow. This is a simple due to the turbulence the effect of the pickling medium optimally accentuating falling film of the pickling medium on the pickling material.
  • the pickling medium can additionally, preferably according to a preferred embodiment of the invention in one or more pickling cells on the inlet side of the system at least one high pressure pump supplied high pressure nozzles for spraying the Pickling medium to be provided on the material.
  • the tape can be rinsed or at least kept moist, if devices are provided on at least one strand of at least one additional cell to bring the material into contact with a rinsing liquid.
  • a variant of the invention is for moisturizing alone without proper rinsing action Suitable system in which mist nozzles are provided to Bring rinsing liquid into contact with the material.
  • Simplifications in the apparatus structure of the systems can be done in one embodiment can be achieved in which the facilities for supply and discharge the pickling liquid or rinsing liquid and for storage and / or treatment of the liquid for all strands of a pickling cell combined into one system are.
  • the devices for Supply or discharge of the pickling liquid or rinsing liquid and for storage and / or treatment of the liquid for at least two pickling cells, if necessary also of all pickling cells are summarized.
  • An additional change in the effective pickling length can, albeit in terms of equipment a little more complex than simply switching individual strings on or off or cells, can be achieved in that devices in at least one cell provided for changing the height of at least one of the vertical strands are. This can, for example, height-adjustable guide rollers or the like. his.
  • FIG. 1 shows a system according to the invention with five two-legged Pickling cells and a system for the pickling medium common to all pickling cells
  • 2 shows a variant with separate systems for the first three or the last two pickling cells
  • Fig. 3 shows an embodiment accordingly Fig. 2 with an additional high pressure part.
  • the strip or wire-shaped pickling material 1 to be treated enters the system via a first deflection roller 2 and becomes via this deflection roller 2 belonging to the first of the two-strand pickling cells 3 deflected essentially vertically downwards into the first strand 4.
  • a lower deflection roller 5 is provided instead of the cell 3, via which the pickling 1 in the second, again substantially vertical strand 6 of the first metering cell 3 is deflected and upwards to the second upper deflection roller 7 arrives.
  • This second upper deflection roller 7 is part of the first Beizelle 3 and the second Beizelle 3a of the system, which is shown in the Embodiment has the same structure as the first, previous Pickling cell 3 and also the following three pickling cells, according to which the pickling material is the Leaves system via the last upper pulley 8 again.
  • the height of the individual pickling cells 3, 3a can depend on the number of available Cells and the desired maximum and / or minimum effective pickling length vary.
  • the effective pickling length of the individual strands i.e. the length between the uppermost contact point with the pickling liquid 9 and their detachment from pickling material 1 is between one and 10 meters, preferably heights between 3 and 6 meters are chosen, ideally about 3.5 meters.
  • five pickling cells 3, 3a are effective pickling lengths to reach a maximum of 35 meters, but on a horizontal length of about 10 meters, i.e. less than a third the length of a conventional one Horizontalbeize.
  • each pickling cell 3, 3a preferably each individual strand 4, 6, the pickling medium, preferably Acid or mixed acid, the respective strand 4, 6 via the overflows 11 fed or this supply be throttled or completely blocked.
  • the eventual Flushing liquid circuit is not shown in the drawing figures, while the circuit of the pickling liquid can be seen schematically, that next to the pickling cells 3, 3a and the overflows 11 (and / or the high pressure nozzles) also the corresponding ones Line systems 12, one or more pumps 13, at least one Tank 14 or collecting container and associated processing, not shown, Includes filter and similar devices.
  • the tank 14 can, as in 1 is shown to be assigned to all pickling cells 3, 3a.
  • a squeeze roll 15 can advantageously be provided on the last deflection roller 8 via which the pickling 1 emerges from the system.
  • the first three pickling cells 3, 3a of the system have a common one Circuit, characterized by the pump 13a and the associated tank 14a.
  • the last two pickling cells 3 of the system of FIGS. 2 and 3, however, are supplied by a separate circuit in which the pump 13 and the tank 14 are located. It is advantageous in the transition between the last cell 3 of the first circulatory system 13a, 14a and the first cell 3 of the second circulatory system 13, 14, which transition over the common Deflection roller 7a takes place, a squeeze roller 15a is also provided.
  • in principle can separate circuits for the pickling medium or any kind of in the Cells 3 used liquids or media for all or only some Pickling cells, groups of pickling cells or just individual strands 4, 6 one or several pickling cells 3, 3a can be provided.
  • Which of the pickling cells 3, 3a or strands 4, 6 with the desired shortening of the effective pickling length switched off by closing the shut-off devices 10 depends on the type of stain and the desired stain characteristics, in most cases, the disconnection started from the end of the system is at which the pickling 1 occurs.
  • Another possibility of changing the effective pickling length is a change the height over which the pickling material in the vertical areas of each pickling cell 3, 3a can be brought into contact with the pickling medium. This can be both by changing the height of the overflows 11 and / or the high-pressure nozzles 17 happen in relation to the lower deflection roller 5 of each pickling cell, for what either the overflows 11 or high pressure nozzles 17 and / or preferably the lower guide rollers 5 can be height-adjustable.
  • Individual or all cells 3, 3a of the system according to the invention can also be devices included, which the application of the pickling material 1 with electrical Electricity is used to support the pickling effect or the electrolytic Pickling or other electrolytic treatments achieving the above to enable mentioned advantages.
