UNITED STATES PATENT OFFKIE SIPHON FOR DRIERS Hervey G. Cram, Appleton, Wis.
Application September 13, 1950, Serial No. 184,631
Claims. 1
This application appertains broadly to steam heated cylinders for drying a web or sheet in paper making machines, and more particularly to a novel syphon arrangement for removing condensate from a steam heated cylinder and said invention is an improvement over my prior United States Patents Nos. 1,919,416; 2,049,050; 2,224,857 and 2,299,530 issued to me respectively, on July 25, 1933; July 28, 1936, December 17, 1940 and October 20, 1942.
One of the primary objects of my present invention is to provide a steam joint construction having novel means for ensuring positive alignment of the steam joint body with the clamping ring carried by the cylinder trunnion, and with the pivotal slip ring disposed between the body and the trunnion, the construction being such that the horizontal section of the syphon will also be properly supported by the steam joint and in axial alignment with the center of the trunnion and cylinder.
Another salient object of this invention is to provide a novel syphon construction in which the inside syphon leg can be readily radially aligned with an operating hand lever for indicating the exact position of the inside leg in said cylinder or trunnion and the relation thereof to the outside syphon leg.
A further important object of the invention is to provide a support tube for the syphon and more particularly for the horizontal section of the syphon with a novel support between the tube and the inside syphon leg including a novel construction between the tube and syphon, whereby the syphon will have limited turning movement in the tube.
A still further object of the invention is to provide a novel syphon construction in which the syphon and tube can be readily removed from and inserted in the drying cylinder or drum, with means for accurately positioning the inside syphon leg in the cylinder or drum.
A still further important object of the invention is to provide means whereby the syphon and steam joint will be properly balanced and supported.
With these and other objects in view, the invention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described and claimed,
and illustrated in the accompanying drawings, in which drawings,
Figure 1 is a fragmentary, vertical section illustrating the novel syphon disposed within adrying cylinder or drum.
Figure 2 is an enlarged detail fragmentary sectional view, taken on the line 22 of Figure 1, looking in the direction of the arrows illustrating the improved steam joint.
Figure 3 is a vertical sectional view taken on the line 33 of Figure 1, showing the steam joint and steam inlet pipe in end elevation.
Figure 4 is a detail vertical sectional view taken on the line 4-4 of Figure 1, looking in the direction of the arrows illustrating the novel connection between the inside syphon leg and the supporting fork carried by the supporting tube.
Figure 5 is a detail horizontal sectional view taken on the line 5-5 of Figure 1, looking in the direction of the arrows illustrating the inlet syphon shoe.
Figure 6 is a detail vertical sectional view taken on the line 6-6 of Figure 1, looking in the direction of the arrows, showing the insidesyphon leg and illustrating the limited movement thereof relative to the supporting tube.
Figure 7 is a view similar to Figure l, but showing the syphon being removed from the cylinder through the steam joint.
Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter S generally indicates the novel syphon for a steam heated drying cylinder C.
The cylinder C is of the type now generally employed in drying a paper web or sheet and hence includes the outer cylindrical wall [0, and an end plate or hub l I. The axial center of the hub plate ll carries a hollow trunnion l2, which is mounted within suitable bearings (not shown) in the paper drying machine.
The syphon S includes a horizontal section 13, which normally extends through the trunnion l2 and into the cylinder and through a steam joint Hi. Thi steam joint I4 is coupled with the trunnion l2 so that the trunnion will have free turnin movement relative to the joint. This joint 10 will be later described in detail. The syphon also includes the inner syphon le l5, and the outer syphon leg l0, and the syphon section I3 is coupled with the inside syphon leg IS in a novel manner, which will also be later described.
The steam joint l4 includes a body I! and an inlet I8 and an outlet I9. The inner face of the outlet 19 is concaved to form a seat for the pivotal bearing ring 20. This ring 20 bears against a pipe joint section 2| which is firmly united to the trunnion l2 by a collar 22 and machine screws 23. The outer end of the joint pipe section 2! is provided with a flange 24. A
clamp ring is disposed about the pipe joint section 2| and suitable anti-friction bearings 25 are interposed between the clamp ring and the flange 24, so that the joint pipe section 21 will have free rotation within the clamp ring. The clamp ring 25 is coupled with the steam joint body H in a novel manner which will now be described.
The steam joint body H has formed thereon, preferably on opposite sides thereof, longitudinally extending substantially cylindrical enlargements 2'! having horizontal ways therethrough, and these enlargements slidably receive sleeves 28 fixed to the clamp ring 25. The sleeves 28 have a close sliding fit with the steam joint body I! and the body slides bodily toward the clamp ring. Enclosed within the sleeves 28 are compression springs 29 through which extend centralizing bolts 30, sliding on which are washers 3| which bear against the heads of the screws and the washers have bearing against the same, the inner ends of the compression springs 29. The outer ends of the compression springs bear against collars 32 which are fixed to the sleeves 28, adjacent to the outer ends thereof. The outer ends of the bolts have threaded thereon nuts 33, which bear against the outer faces of the tubular sections 21 of the body H of the steam joint. The adjustment of the nuts 33 determines the cushioning pull on the sleeves 28 and this cushioning pull is transferred to the clamping ring 25 and the pivotal slip collar 20. This provides a positive alignment of the steam, joint body II with the clamping ring 25 and this in turn also insures correct alignment of other parts, as will later appear.
The weight of the steam joint body 13', is approximately counter-balanced by the syphon S on the pivotal slip collar 28, and, the total weight of the steam joint body I! and the syphon S is supported by any preferred means, such as, the steam inlet pipe 34, the upper end of which is received within the inlet [8 of the body H. The steam pipe 34, is, of coiu'se, subject to changes in temperature and consequently, to expansion and contraction. Therefore, the steam inlet pipe includes upper and lower sections 35 and 36 coupled by an expansion joint 37.
In order to effect an accurate alignment of the steam joint body IT and the syphon S with the axis of the dryer cylinder, a supporting arrangement is provided, which embodies a sole plate 38 set in the floor and this sole plate encircles the lower section 36 of the steam inlet pipe 3 Secured to the sole plate 38 are a plurality of stay rods 39, which support a fiange 4% which is fixed to the upper section 35 of the steam inlet pipe 3G. The flange 40 is located in close proximity to the steam joint 14 and the upper and lower nuts 4! are carried by the stay rods 39 and engage the upper and lower faces of the flange 40. The expansion joint 3'! permits proper adjustment of the nuts 4|.
The outer end of the steam joint body H is closed by a cap 42 and the cap is removably held in place by machine screws 43. This cap 42 has a close and tight fit with the body 17, and is provided with a smooth shoulder 44, which snugly engages the inner surface of the body ll. Also formed on the cap is the inwardly extending supporting sleeve 45, which has fixed therein the horizontal supporting tube it, and this tube normally extends from the cap 42 through the trunnion l2 and into the dryer cylinder C. The tube 46 receives the horizontal section 13 of the syphon S and a packing gland A1 is carried by the head for this horizontal section 13. By detaching the cap 42 from the syphon body H, the entire syphon with the supporting tube 46 can be withdrawn from the cylinder C and its trunnion (2, as will later appear.
The upper end of the inside syphon leg I5 carries the syphon elbow 48 and the horizontal section 13 of the syphon threads into the upper end of the elbow. The elbow has formed thereon (see Figure 4), an enlargement E9, and this enlargement is received between the ears 58 of the fork member 5|, which is carried by the supporting tube 46. A pivot pin 52 extends through the enlargement 49 and the ears 58, which allows free swinging movement of the inner syphon leg IE on the supporting tube. The fork member 5| carries a limiting pin 53, which is received within a semi-circular slot 54 formed in the supporting tube 46 adjacent to its inner end. Consequently, the fork member 51 and the syphon leg [5 and other parts of the syphon have limited turning movement within the supporting tube.
The lower end of the syphon leg 15 has threaded thereon the syphon inlet shoe 55 and this shoe, see Fi ure 6, is provided with a restricted inlet 56. A wear flange 51 is removably attached to the inlet head and preferably has bearing engagement with the inner surface of the cylindrical outer wall of the dryer cylinder or drum, and in actual practice the flange 5'! wears into proper engagement with the inner face of the cylinder during the rotation thereof.
The outer leg it of the syphon is connected to the horizontal section l3 through an elbow 58 and a joint 59. Incorporated in the length of this syphon drop or outside leg i6, is a combination sight glass and expansion joint 68. This combination sight glass and expansion joint allows movement for expansion in accordance with the expansion of the steam pipe 35.
Secured to the horizontal section 13 of the syphon between the steam joint 14 and the syphon leg I6 is a hand crank 6!, the purpose of which will be later described.
In assembling the syphon with the dryer cylinder or drum C, and considering that the cap 42 is removed from the steam joint 14, and that the supporting tube 66 has already been assembled with the cap and the horizontal syphon pipe section 3 with the tube; then the inner leg 15 of the syphon is swung on its pivot 52 and is inserted, into the trunnion i2 through the cap opening in the steam joint 14, and the entire syphon is slid longitudinally through the trunnion, as shown in Figure '7. When the inner syphon leg reaches the cylinder, the same will drop down by gravity into the cylinder with the syphon head 55 engaging the inner surface of the cylinder. The cap 42 can now be secured in place by its screws 43, and by turning the crank fil, the horizontal syphon section I3 is threaded into the elbow 48 carried by the inner leg of the syphon (see Figure 1). When the section I3 is threaded to its fullest extent into the elbow 48, then the section l3 and the inner leg I5 can be turned as a unit, at which time the pin will move in the limiting slot 54. The crank BI is locked to the syphon pipe section [3 in exact radial alignment with the inner syphon leg l5, and by turning the crank, the syphon leg l5 can be raised or lowered to suit different syphcning conditions and the crank will indicate the position of the leg in the cylinder. After the assembling of the syphon in the cylinder, the syphon section I3 is connected to the outer syphon drop leg l6 through theuse of the elbow or the joint 59. When it is desired to remove the syphon, for any reason, from the cylinder, the joint 59 can be'taken apart and the cap is again removed and the entire syphon can be instantly pulled out of the cylinder. During the assembling of the syphon and the pulling of the syphon out, the packing gland can be suitably loosened or tightened as desired.
Great stress is laid on the lining up of the steam joint and the novel arrangement of the syphon itself in conjunction with the inner leg and the crank 6 l.
