Air injection nozzle for pipes in pneumatic transporting systems has filter disc and tip of recoil element's sealing lip spaced close to zero in order to minimize gas volume in between and to effect intensive regeneration of filter disc

摘要

The air injection nozzle for pipes in pneumatic transporting systems has a filter disc (7) and recoil element (8). The filter disc and tip of the recoil element's sealing lip (11) having a spacing close to zero in order to minimize the gas volume included in between and to effect intensive regeneration of the filter disc. The recoil element forms an annular gas jet which impinges on the filter disc. The filter disc consists of a structured sintered material with varying porosity in the form of different layers.
