Claims.
This invention relates to washing devices which are known as shower pipes such as are used for Washing or cleaning strainers, felts, etc., in paper and pulp mills. It is particularly adapted for cleaning shower pipes 'similar to those shown in the patent to Witham, Shower pipe, August 28, 1934, No. 1,972,001 and those shown in the patent to Paramor, Washing device comprising' shower pipes, April 16, 1935, No. 1,997,651.
In this class of shower pipes, there is a longitudinal pipe through which the water flows and this pipe has a plurality of openings or nozzles spaced longitudinally.
In some cases, projecting nozzles are used, in other cases radial cylindrical holes are used and in the case of Witham, there are aligned orifices which connect on the outside with one groove and on the inside with another groove.
As the stock contains a good deal of solid material, it is necessary that these nozzles, holes or orifices should be cleaned from time to time and it is desirable that the liquid which flows through them should be spread out in fan shape.
It is also desirable that the cleaning device should not obstruct the flow of water to any extent.
There are now various types of disks or segments carried by a rod extending axially through such a pipe, such rod sticking out through the end of the pipe so that it can be either revolved by a crank on the outside or pushed back and forth manually.
I nd that by using a groove on the inside of the pipe associated with an orifice and by moving a radially disposed cleaning member such as a flexible but stiff brush at regular intervals through the groove and proximate the orifice, the whirling action which is relied upon in other devices for cleaning the holes is replaced by an actual sweeping action which thoroughly cleans the groove and the orice.
Preferably I also arrange these brushes or other cleaning devices in such a position` that most of the time they do not obstruct the ilow of the water either longitudinally or through the nozzles or orifices but at pre-determined intervals by automatic devices outside the pump, they are caused to sweep through a groove, thus cleaning it and the orifice.
In the drawing:
Fig. 1 is a diagrammatic transverse sectional view of a paper machine with my device attached, parts being shown in full lines and parts in section.
Fig. 2 is an end elevation as from the right oforifices.
Fig. 7 is an end elevation showing one type .of driving mechanism outside the shower pipe with connections.
Fig. 8 is a View similar to Fig 4 showing another type of shower pipe with my cleaning device.
Fig. 9 is a view similar to Fig. 6 of a shower pipe with a modication of my cleaning device.
Fig. 10 is a front elevation of another type .of outside power driving mechanism with connections.
Fig. 11 is a View similar to Fig. 4 of a modication of my cleaning device.
Fig. 12 is a View similar to Figs. 4 and 11 of another modication of my cleaning device.
Fig. 13 is a view similar to Fig. 9 of another v modication.
Fig. 14 is a transverse vertical sectional view of another type of shower pipe with a modification of my cleaning device in position.
In the drawing, 4 is the wire pit .of a Fourdrinier machine and 5 is the wire. Over this eX- tends the spray pipe A in which are the aligned nozzles N, each of which, as shown, in Figs. 3 and 4, comprises a threaded hole or opening I9 in which is a button 20 threaded at 2| to t the threads in opening I 9 and having on the inside a groove 24 and on the outside a groove 23 at the intersection of which is the orice 22, substantially as shown in the patent to Witham on Shower pipes, No. 1,972,001, of August 28, 1934.
C represents my cleaner which comprises a rod I which extendsaxially through pipe A and through a passage 2 in one end and which carries a plurality of brushes 3. brushes are of stiff wire and they are in position on nod in the same transverse plane as the openings IS, I9 and orices 22, 22 and preferably each is substantially in the same plane with an inside groove 24 so that when the rod l is turned or reciprocated, each brush 3 will sweep through an inside groove 24 and thus clean the orifice 22.
P represents .power means which, as shown in Figs. 1 and 2, comprises an arm 6 xed to the end Preferably these `members 58.
4 of rod I and having a weight 'I on one branch and a bucket I suspended on the other end. In bucket I0 is fixed a siphon II which extends down through the bottom so as to discharge into a waste receiving pan I2 which empties into a waste pipe I3. As shown, the liquid from the main feed pipe O which feeds the pipe A is conducted by a small pipe I4 into the bucket I0 so that it gradually ills up until the liquid reaches the top of the siphon II, upon which the Siphon empties the bucket.
The result of this is that the weight 1 normally overcomes the weight of the liquid in the bucket and normally keeps each brush 3 .out of the way of an orice 22 and its inside groove 24, but when the liquid overbalances the weight 1, it causes the brush to sweep through groove 24 and clean the orice 22. VAs the liquid continues to run out through pipe I3, the parts are so balanced that very soon the siphon clears the bucket of liquid and the weight acts again `and brings the brush back to itsvusual position, as Yshown in dotted lines in Fig. 2.
I prefer this intermittent action in which the sweeping through the groove is quickly done as thereby there is little obstruction to the passage of the liquid through the nozzles and of the pipe A.
However, I may use -a continuous in place of -an intermittent rotary motion such as shown in Figs, 6 and 7, or a reciprocal axial motion such as shown in Figs. 9 and 10, and I may use any of the various types of motors outside the shower pipe, such as shown in Figs. 7 and 10.
In Fig. 6, I show a pipe B in which are holes or nozzles 30 which `are of cylindrical form and the rod `3| carries brushes 32, 32. In Fig. Y7, is shown the drive mechanism for rod 3I `which includes `a large gear` 34 driven by a'small gear 36 and motor R. In this case, each brush moves continuously around 360, passing each outlet 3D on its way.
Motor R may be electric, water, or any type, or gear 33 might be run -by its shaft |36 being con nected `by belts or otherwise to any revolving part of thepaper'mill machinery.
In Figs. 8, 9 and 10, Ishow how a reciprocal axial motion instead of a rotary motion can be used.
In Fig. 8, I show Va pipe F with a single, long groove 4I through which are the cylindricalforicesg4, 49. 42 is an axially disposed rodwhich carries brushes '43,the normal position of which is between two holes such vas 48. As shown in Fig. 10, this rod 42is reciprocated by a connecting rod 38 from a'large gear 44 in which is a pin .'145, the pin :45 being the pivot for connecting rod 38, so thatl as the small gear 46 meshes with the large gear 44 and is revolved by any suitable driving mechanism such as a motor T, the rod"42 and the brushes are caused to reciprocate, thus cleaning the openings.
As shown in Fig. 9, I may use 'a pipe G with aligned orifices 4'I, veach with a lengthwise, inside, individual groove 4B and a rod 5I! carrying cleaning members shown as brushes 49, the rod being reciprocated by any power means outside the pipe G such as a motor T and connecting rod 38gas shown in Fig. l0.
fInstead of brushes, I vmay, as shown inFig.
`1l, use a shower pipe H with inserted nozzles :I, each having an inside'groove 53 and an outside groove 52 with the orifice 54 between them and a shaft 55 which carries the rigid cleaning Each member 56 is'shown as having three arms such as 51 and each of which carries a shoe such as 58 which ts inside pipe I-I, each of these cleaning members being in the same transverse plane with the oriiice 54. As shown, this cleaning rod and member may be reciprocated circumferentially, as shown by the arrows, by any suitable power means.
As shown in Figs. l2 and 13, I can use in connection with a pipe K inserted nozzles 6U, each with an inside groove 62 and an outside groove -I with an orifice 64 between them and cleaning members such as 65, each carried by a cleaning yrod-63 and each including supporting arms 66 which support the rigid, annular cleaning members v6I. As shown in Fig. 13, the cleaning rod and cleaning members can be reciprocated vaxially of pipe K by any suitable motor.
As shown in Fig. 14, I can use with a shower pipe L having projecting nozzles 10, each with an orifice 1I, a cleaning rod 14. This rod I4 is slidable in bearings I6 in a bracket 'I5 in a direction parallel with the axis of pipe L, and is provided with projections 13 which carry brushes 12, each brush in a position to clean an orifice 'II When rod 'I4 is reciprocated axially by power means outside of pipe L.
