Abstract
A suction pipe assembly (10) for dewatering a web in a papermaking machine includes a rotating pipe supporting suction cover (38) and attached to a frame (12) by a bearing sleeve (52). Support members (54, 56 and 58) extend from the bearing sleeve (52) to the pipe without obstructing the flow of air through the pipe.
Claims
1. A suction pipe assembly for dewatering a web in a papermaking machine comprising: a frame; a hollow pipe extending along a longitudinal axis and having a first end rotatably mounted on said frame, a second end opposite said first end being fixedly mounted on said frame, and suction means for applying suction to said web,; a shaft disposed in said hollow pipe; support means mounted on said shaft for supporting said pipe on said shaft; vacuum supply means for applying vacuum to said pipe; and bearing means for rotatably supporting said pipe on said frame near said first end.
2. The assembly of claim 1 further comprising sealing means for vacuum sealing said second end.
3. The assembly of claim 1 wherein said bearing means includes a sleeve and said shaft includes a shaft end slidably engaging said sleeve.
4. The assembly of claim 1 wherein said pipe includes rotating means for selectively rotating said pipe.
5. A suction pipe assembly for dewatering a web used in papermaking, said assembly comprising; a frame; a fixed pipe section mounted on said frame; a rotating pipe section rotatably supported by said frame, said fixed and rotating pipe section having a common longitudinal axis and being disposed in an axially spaced relationship; each said pipe section having a closed end supported by said frame and facing open ends opposite said closed ends; sealing means for sealing said open ends; pipe support means disposed at said open ends to support said pipe sections; suction means supported by said rotating pipe for applying suction to said web; vacuum supply means for applying a vacuum to said pipe section; and whereby said rotating pipe section is selectively rotated with respect to said frame for cleaning.
6. The assembly of claim 5 wherein said pipe support means includes a rotating bearing.
7. The assembly of claim 5 wherein pipe support means includes a shaft extending coaxially with said longitudinal axis in one of said rotating and fixed pipe sections, and a sleeve extending coaxially with said longitudinal axis in the other of said fixed and rotating pipe sections, said shaft and sleeve cooperating to form a sleeve bearing.
8. The assembly of claim 7 wherein said support means further includes a member extending from at least one of said sleeve and said shaft to one of said rotating and fixed pipe sections.
9. A suction pipe assembly for dewatering a web used in papermaking, said assembly comprising; a frame; a fixed pipe section mounted on said frame; a rotating pipe section rotatably supported by said frame, said fixed and rotating pipe section having a common longitudinal axis and being disposed in an axially spaced relationship; each said pipes having a closed end closed to the atmosphere supported by said frame and facing open ends opposite said closed ends and an elongated member extending coaxially with said longitudinal axis; sealing means for sealing said open ends; pipe support means disposed at said open ends and extending from said elongated member to an inner surface of said pipe sections said pipes; bearing means for rotatably coupling said elongated members; suction means supported by said rotating pipe for applying suction to said web; vacuum supply means for applying a vacuum to said pipe section; and whereby said rotating pipe is selectively rotated with respect to said frame for cleaning.
