Abstract
A self-cleaning filter apparatus for use in removing particulate matter from a transport fluid, such as air, which includes a housing having a pair of spaced pulleys over which an endless filter belt is positioned to present two generally straight filter reaches and two generally curved filter reaches. The endless filter belt includes a permeable substrate formed as an endless belt and a plurality of pleats of filter media extending outwardly from the surface of the substrate so that the transport fluid can pass inwardly therethrough and deposit the particulate material on the exterior surface of the pleats.
A suction nozzle and/or an air discharge device is positioned adjacent the outer surface of the endless filter at one of the curved reaches thereof for removing particulate matter deposited on the pleats as they pass along such curved reach. The filter belt may be supported for movement by the housing at the opposite side edges of the filter belt, and the housing supports may be provided with suction channels for sealing the side edges of the filter belt.
