Blower for an air/water separator in a paper-making machine |
摘要 |
A paper-making machine includes a wet end associated with a wet fiber web, a headbox having an outlet gap, and a forming fabric positioned adjacent to the outlet gap and moving in a direction of web travel. An air/water separator is positioned in association with the forming fabric and downstream from the headbox relative to the direction of web travel. The air/water separator is configured for receiving liquid from the fiber web. A blower having a housing and an impeller is fluidly connected with the air/water separator. The impeller is rotatably carried by and within the housing and has a rotating hub with a periphery. The impeller also has a plurality of vanes attached to and extending from the hub and substantially equally spaced around the periphery. The vanes are formed of a non-metallic, composite material and have a coating of a layer of hydrophobic material substantially covering the composite material.
