PRODUCTION LINE FOR GALVANOCHEMICAL TREATMENT OF PARTS Russian patent published in 1999 - IPC

FIELD: production lines for galvanochemical of coating with meeting high ecological requirements for production. SUBSTANCE: production line has baths of main process treatment and washing; unit for preparation of parts surface; system of heating and cooling of working media; appliances for parts installation; ventilation system for trapping vapors, gases and aerosols; store for process media and equipment; movable vessel for taking from store and discharge of process media into any process vessel; process media regeneration unit consisting of electrochemical device and apparatus for distillation and rectification, treatment with sorbents and reagents. Ventilation system has entrainment separator and antimist filters on bath air intakes, and also trap of harmful impurities. All units and assemblies of production line are of module design. Electrochemical regeneration unit may be provided with insoluble anode, membrane chamber and conducting membrane, for instance, ionite membrane. Harmful impurity trap may have device for air treatment with liquid absorber, spray separator, for instance, lover entrainment separator and antimist filter. Movable vessel is equipped with vacuum pump, for instance, ejection pump. Preparation department is furnished with device for electric pulse treatment of parts. Invention allows establishment of galvanochemical production if form of single process complex with closed cycle of process media without liquid and harmful gas effluents. EFFECT: higher efficiency. 5 cl, 1 dwg
