Specification of Letters Patent. Patented 1 gb, 24, 1920,
Application filed June 24, 1919. Serial No. 306,511.
7 '0 all whom it may coac em: Be it known that I, J noon O'r'ro Lonnnnne, a subject {of the King ofNorway, residing at Torp, Borge, near Fredriksstad, Norway, have invented new and useful Improvements in Steam-Inlets and Water-Outlets of Drying-Cylinders, of which the following is a specification. p i
As will be known, the water] outlet tube in steam heated drying cylinders, for instance, such as areemployed in paper. machines, are often exposedto, wear and tear, caused by the fact'that this tube owing to incorrect mounting, expansion or for other reasons, is brought out of its concentric position and bears against the inner wall of the hot hollow cylinder shaft or trunnion. If the Water outlet tube (the so called siphon tube) is damaged, the cvlinder is filled halfway with condensing water, which involves an increased consumption of steam, danger of explosion, increased pressure of bearing with liability to getting hot, increased consumption of lubricant, and further, a greater motive force and increased consumption of felt, leakage around screws and packing, breakage of the cylinder shaft and consequently a cessation of work and expensive repairs. The position and the absolute tightness of the siphon tube, must therefore be under perfect control, in order to obtain a reliable and economical working of the device.
In the common steamand water-boxerrangement such control is diflicult and expensive, and also entails considerable trouble 7 and waste of time, because the steamand condensing water connections as well as the fastening bolts of the box must be loosened.
These disadvantages are avoided by arranging the steam inlet and the water outlet of the drying cylinder in accordance with the present invention, which is shown in the accompanying drawing.
Figure 1 is a longitudinal section through one end portion of a drying cylinder provided with the improved device for coupling the steam and water conduits.
Fig. 2 shows on a larger scale a longitudinal section through the coupling device. The
drying cylinder 1 has as usual a hollow endshaft or trunnion 2 adapted to rotate in bearings (not shown). Through the trunnion 2 the water outlet tube 3 communicates with the interior of the cylinder, while steam is conducted into the interior of the trunnion by means of a tube :10. The tube 3 may be r a common siphon tube as shown in theidrawing, or it may. be connected to a scooping device (not shown) in the interior of the cylinder, by'means of whichithecondensing water in the lower part of the cylinder is taken up and let out throughthe tube 3.
a-kccordingto the invention the outer end of the tube 3 is: fastened concentricalwith the trunnion 2 in a flanged cap 4w.or' the .like, on the outer side of:the stationary boxshaped continuationo of the trunnion 2, so that the tube 3 with thecap .4 can be removed orreplaced without any disconnection-of the tubeconduits being necessary. The-rend of the cap .4 is closed by almember-{linwhieh is secured an observation glass. 6. I
' The steam passes from the main conduit 7 through the lateral tube 8 into the box 5 and then into the steam tube 10 through radial openings 9 in the same, whereupon the steam is conducted into the hollow interior of the trunnion 2 a.ndthence into the drying cylinder 1. The condensing water in the cylinder is conducted through the tube 3 out into the outer compartment 11 of the cap 4 and thence through conduit 12in the box or coupling piece 5 down through the water conduit 13, through the condensing vessel 14 and out through the tube 15.
The tube 3 is at the inner end of the steam bility of displacement of the box. Furthermore, through the glass 6 of the cap 4at the end of the siphon-tube it may easily be observed whether condensing water alone is passing through or whether steam also is escaping, which latter fact indicates defects in'the condensing vessel, whose correct func tion in this simple manner may be examined in' a reliableway.
As previously stated the present construction also removes the disadvantages that lubricant from the bearing faces 17 of the caused by the fact that the oil in the interior of the cylinder formed a coating which obstructed the transmission of heat, thereby increasing to a considerable amount the consumption of steam. Another drawbackwas,
that the condensing water carried oil into the boiler, whereby an insulating coating was formed, the consumption of coal increased and the boiler tubes destroyed because theybecame burned and crooked, thus involving danger of explosion.
Having now described my'invention, what I claim as new and desire to secure by Letters Patent is 1.' The combination with a drying cylinder provided with a hollow trunnion, of a steam inlet tube communicating with the interior of said trunnion, a water tube extending through said trunnion and steam tube and a deflecting member between the inner end of said steam-tube and the water tube, said deflecting member and tubes being rigidly secured in concentric relation to the cylinder.
2. The combination withla drying cylinder having a hollow trunnion, of a steam inlet tube communicating'with the interior of said trunnion, a water tube extending through said trunnion and steam tube, and a deflecting ring surrounding said water tube and secured to the inner end of said steam tube, said ring and tubes being rigidly secured in concentric relation to the cylinder.
3. The combination with a drying cylinder having a hollow trunnion, of a remov able cap for closing the end of said trunnion,
a steam inlet tube and a water outlet tube secured in said cap and maintained in concentric relation wlth said trunmon, and a transparent member secured in said cap thereby to permit observation of said water tube.
In testimony whereof I have signed my name to this specification.
