STRUCTURE OF BAND FOR SUPPORTING INTERVAL OF CUTTING VALLEY FOR CARTRIDGE FILTER

摘要

A band structure of supporting an interval of bent valley of a cartridge filter is provided to extend the lifetime of the cartridge filter and reduce the repair cost due to replacement of the cartridge filter, by supporting bands of the cartridge filter using snap rings. A band structure comprises a first band(20) installed outside a cartridge filter(10) of an air adsorption tower installed at an input side of an air compressor, a second band(21) installed inside the cartridge filter, and snap rings(30,31) respectively at the first band and the second band to support the first and second bands. The band structure keeps intervals between bent valleys of the cartridge filter uniformly, and increases the sectional area of the cartridge filter.
