ABSTRACT:
Washers for cleansing metal parts, filters, quartz tubes and the like are either drum washers, or washers in the form of cabinets equipped with sprays. Industrial washers are washers adapted for assembly line cleaning of metal parts. Separate treating zones lead to the highly cleaned metal surfaces required by many coating processes. A conveying means is usually installed in the ceilings or floors of such washers for continuous transport of fabricated metal articles therethrough, and tanks are disposed in the base of such washers. Chemical cleaning agents utilized in industrial spray washers have a significant corrosive effect on the washer equipment. Herein a life-extending solution to the corrosion problem is provided. Plastic panels are carried by framework members to form a housing over the tanks, spray assemblies and drain areas. A feature herein is the provision of framework members in the form of elongated expansion seals carrying the plastic panels while permitting expansion and contraction of the panels without buckling, without leakage or loss of seal despite differences in rates of thermal expansion of plastic and metal.
