DEVICE FOR APPLICATION OF PROTECTIVE COATINGS TO PIPE SURFACES

摘要

equipment for application of coatings to surfaces of cylindrical articles by dipping; applicable in chemical, machine-building and other industries for application of anticorrosive coatings to pipes and air ducts operating in corrosive media. SUBSTANCE: device has extensible grips made of plates in form of cross-piece; bag filter; ventilation system and body separated in length into two sections by wall. Placed into one section is bath. Wall has window located at bath level and communicating the sections with each other. Section with bath has overhead conveyer passing through bath. Conveyer passages are made in form of body apertures with gates. The other section is made in form of packed absorber with spraying nozzles and absorbent collector. In this section, partition is installed over entire width to form free space together with wall. Free space is communicated successively through packed absorber and bag filter with ventilation system. Upper edge of partition is located under spraying nozzles, and its lower edge, above absorbent collector. Located in free space above window is plate to form hydroseal together with slot on partition side. EFFECT: reduced solvent vapors in working zone and effluents to atmosphere. 2 dwg
