Definitions

  • ABSTRACT An improved spray type apparatus for treatment of a metal surface with an aqueous solution containing a chemical reagent is disclosed.
  • the apparatus' has a spray chamber including a treating region, where the aqueous solution is sprayed onto the metal surface, and a rinsing region where rinsing water is sprayed onto the metal surface whiclh has been previously treated at the treating region.
  • the improvement includes the rinsing region having one zone as a last zone and at least one other zone.
  • Conducting means are provided between the zones and the treating region such that the water, after rinsing, can flow from the last zone through all the other zones to the treating region.
  • a supply means for providing fresh water is provided at the last zone and an evacuating means is mounted above the treating place so as to eliminate water therefrom in a vaporized form.
  • the present invention relates to an improved spray type apparatus for treatment of a metal surface with an aqueous solution containing a chemical reagent.
  • FIG. 4 is a schematic sectional view of a conventional spray type apparatus wherein 1 is a metal substance to be treated, 2 is an overhead-conveyer for transporting the metal substance and 3 is a spray chamber provided with fan-attached ducts 4 and 4' respectively at the inlet and the outlet.
  • the spray chamber 3 is usually divided into several zones depending on the kind of the treatment.
  • the spray type apparatus as shown in FIG.
  • the spray chamber 3 is divided into five zones, i.e. 3A, 3B, 3C, 3D and 3E, where degreasing, water-rinsing, phosphating, water-rinsing and acidulating are performed, respectively.
  • Each of the said zones is provided with a nozzle 4A, 4B, 4C, 4D or 4E for spraying water or an aqueous solution containing a degreasing agent, a phosphating agent or an acidulating agent (hereinafter referred to as chemical solution”) into the spray chamber 3.
  • Tanks 6A to 6E provided with pumps 5A to SE for sending water or the chemical solutions to the nozzles 4A to 4E, are furnished to the zones 3A to SE respectively and serve as reservoirs for water or the chemical solutions sprayed in the spray chamber 3.
  • the tanks 6A and 6C are provided respectively with heaters 7A and 7C.
  • the metal substance 1 When the metal substance 1 is treated with an aqueous solution containing a degreasing agent in the zone 3A and also with an aqueous solution containing a phosphating agent in the zone 3C, some portions of these chemical solutions are carried from the zones 3A and 3C respectively to the adjacent zones 38 and 3D by the metal substance 1.
  • the rinsing waters in the zones 38 and 3D are contaminated with the chemical solutions, which causes the deterioration of the metal substance 1 in quality.
  • fresh water is supplied to the tanks 68 and 6D so as to maintain a high efficiency of water-rinsing.
  • waste water contains as a matter of course, the chemicals used in the zones 3A and 3C, usually acidic or alkaline substances, metal ions, surface active agents, oils and fats, etc., and the discharge of such waste water may have a serious influence on the environment. Because of this it is desirable to eliminate, harmful components in the waste water. Since, however, an apparatus for purification is quite expensive, the said elimination is usually not practised.
  • the object of this invention is to provide an improved spray type apparatus which is slightly modified from a conventional one but can considerably suppress the production of waste water in quantity.
  • Such object can be attained by mounting an evacuating means on a spray type apparatus, particularly above a zone where a metal substance is treated with a chemical solution,
  • a spray chamber having at least one treating region where a metal substance is treated with a chemical solution and at least one rinsing region where the metal substance, transported from the treating region, is rinsed with water.
  • the apparatus has an evacuating means mounted on the spray chamber, favorably above the treating region.
  • the rinsing region is divided into two or more zones so as to effect water-rinsing by a multi stage system. Fresh water is supplied to the last zone. in the rinsing region, and an excessive amount of water therefrom overflows to the adjacent zone.
  • Such overflowing proceeds successively from one zone to another zone in the rinsing region and ultimately to the treating region, which may be also divided into two or more zones.
  • water contaminated with the chemical so lution carried by the metal substance is discharged from the rinsing region to the treating region, all of the regions being within the apparatus itself.
  • the amount of fresh water to be supplied may be reduced to about 1/20 H10 in the case that the rinsing region is divided into two zones and about l/50 1/20 in the case that the rinsing region is-divided into threee zones, compared with that when the rinsing region consists of a single zone.
  • the chemical solution therein may be diluted with the increase of the amount. Because of the evacuation means mounted on the spray chamber, however, the water is continuously evaporated, and the dilution of the chemical solution and the increase of the amount can be suppressed.
  • the treating region is often heated to around 40 C for efficiently conducting the treatment of the metal substance with the chemical solution, and such heating is apparently advantageous for evaporation of the water. For instance, 1 kg of air can contain 0.0488 kg of water at 40C and 0.276 kg of water at 70C.
  • the amount of water coming from the rinsing region to the treating place can be balanced with the amount of water evaporating from the treating region by selecting an appropriate evacuating means and/or a suitable heating means.
