Definitions

  • the invention relates to a method and a device for operating a multi-stage Countercurrent cascade sink for wet chemical surface treatment the process part or a post-treatment part a system for treatment Metallic belts is connected downstream and at each rinse level a connection to a central fresh water volume supply a rinsing water circulation system having.
  • Such a rinsing process is in the wet chemical surface treatment of great importance. It not only breaks the previous chemical reaction ab, but also achieves a cleaning of the surface of the goods and thus avoids the carry-over of foreign electrolytes into the subsequent process bath.
  • Such Countercurrent cascade rinses are usually the process parts of belt treatment plants, such as strip pickling, downstream, are used but also for rinsing processes in other conveyor systems after cleaning parts, after Treatment parts or post-treatments.
  • the continuous one The belt is cleaned of treatment chemicals and foreign substance residues.
  • the fresh water supplied via a central supply arrangement is in the abandoned in the direction of the last belt and runs in counterflow to the material flow over the individual rinsing stages from separating weirs to the first Rinse level.
  • the fresh water volume flow (cascade flow) is usually dependent regulated by surface throughput, with a minimum cascade flow to Operation of the sink is always required.
  • the rinsing on the surface adhering liquid film diluted with water. So the flushing is over the better the dilution ratio, also known as the rinsing criterion is that of the concentration in the process bath and the concentration in the last rinse is determined, which ultimately for the purity of the treated Parts or tapes is important.
  • the invention has for its object a method and an apparatus to create an improved flushing technology with higher Allow degree of cleaning or greater purity of the items to be treated.
  • This object is achieved with a method according to the invention in that a partial flow from the flushing water circulation system associated with each flushing stage branched off as a bypass stream and the previous rinsing stage is fed.
  • a partial flow from the flushing water circulation system associated with each flushing stage branched off as a bypass stream and the previous rinsing stage is fed.
  • the invention in the flushing water circulation system assigned to each flushing stage separate bypass lines integrated, each at the end of the each previous rinse stage open into this, preferably with on The end of the bypass line is arranged above and below the belt Nozzle pipes.
  • a countercurrent cascade sink 1 shown in the exemplary embodiment, which a treatment part 2, e.g. a stain, for the treatment of a tape running according to arrow 3 continuous metallic band 4 connects, consists of a pre-sink 5 and the subsequent rinsing n as well n + 1, n + 2 and n + 3.
  • the countercurrent cascade sink 1 is the fresh water from a supply source, not shown, via a fresh water volume supply 6 abandoned in the last sink or rinse level n + 3.
  • the single ones Flushing or flushing levels 5 or n to n + 3 are by weirs 7 (see also Fig. 2) separated from each other.
  • Each rinse level n and n + 1 to n + 3 inclusive the sink 5 is assigned a rinsing water circulation system I to IV, via which the individual rinse levels are supplied with the necessary rinse water, which is given up via nozzle arrangements 9, each of which is an upper and have 4 nozzle tube running below the belt.
  • the belt 4 thus experiences an additional one in each of the previous rinsing stages Cleaning with the less loaded rinse water of the following rinse level n + 1 or n + 2 or n + 3.
  • the one always required to operate the countercurrent cascade sink 1 minimal cascade current is thus without an overflow of weirs 7 and thus a carryover of chemicals or foreign substance residues from the maintain the last one to the penultimate sink.
