Bag filter support cage - with sections of plastic injection mouldings coupled by snap fit

摘要

Support cage for insertion into bag filter elements to prevent their collapse under load consists of a pattern of U-shaped rods which are joined by intersecting rings to a cage. The cages are made of a plastic polypropylene or glass fibre reinforced polyester). At the curved end, the dia. is reduced by the thickness of the rods so that the next cage section can be pushed over. It is held by a groove into which its end ring snaps.
