Abstract
The invention contemplates an improved rotary-syphon construction whereby condensate may be syphoned from the inner wall of a rotating drum, for example, a steam-heated dryer. The improvement resides in the particular construction whereby syphon parts are axially removably insertable through a journal bearing at one end of the drum, and whereby internally projecting parts of the syphon derive direct and firm radial-positioning support, thereby relieving syphon-tube parts from any need to sustain the stress fluctuation which would otherwise result from reliance upon cantilevered support of the syphon-tube parts solely at the journal-bearing region.
Claims10
A rotary -syphon assembly for axial insertion into a rotary drum to be heated by a flow of heated fluid, the drum having at the insertion end a main journal with an axial bore, said assembly comprising:
- an elongated supporting tube sized for axially slidable insertion through the journal bore and for firm support in the journal bore when the axially inner end of said tube is cantilevered beyond the axially inner limit of journal-bore support, the cantilevered portion of said tube having an enlarged opening at one angular location and spaced from the axially inner limit of journal-bore support;
- articulated syphon-tube means comprising a horizontal-tube element, a radial-tube element, and a hinged elbow interconnecting said tube elements, said tube elements and elbow being of lesser diameter than the bore of said supporting tube;
- radial-strut means providing direct radial-positioning support of said horizontal tube element with respect to the bore of said support tube at plural axially spaced locations at least one of which is near said elbow;
- the enlarged opening being sized and located to permit said horizontal tube element to pass radially through the enlarged opening upon axial insertion or removal of said syphon-tube means via said supporting tube.
