WASHER CYLINDER FOR PAPER-PULP MACHINES.
Application filed August 16, 1922. Serial No. 5852,2226.
To all whom it may concern Be it known that I, EMIL A. PETERSON, a citizen of the United States, and resident of Appleton, in the county of Outagamie and State of Visconsin, have invented new and useful Improvements in lVasher Cylinders for Paper-Pulp Machines, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.
This invention relates to washer cylinders or drums for paper pulp and similar machines and has for one of its objects to provide a cylinder which will rapidly and efliciently segregate the water from large quantities of pulp.
A further object of the invention is to provide a device of the class described wherein means are provided for the rapid and efiicient discharge of the water so segregated.
A still further object of the invention is to provide a washer cylinder which may be mounted in the trough or tub of the usual and well-known beating engines and which may be efficiently employed either as a washer or as a thickener for the pulp as it is acted upon in the said beater. v
A still further object of the invention is to provide a cylinder of the class described which will be simple in construction, com-- paratively inexpensive to manufacture, and more efficient in operation than those which have been heretofore proposed...
With the above and other objectsin view which will appear as; the description proceeds the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the accompanying claims.
Referring to the accompanying drawings in which like numerals designate like parts in all the views;
Figure 1 is a diagrammatic plan'view of one form of beater illustrating the present invention in place in the trough thereof and in operative relation to the beater roll;
Fig. 2 is a central, transverse, vertical, sectional view of the cylinder construction constituting the present invention;
Fig. 3 is a side elevational view of the parts shown in Fig. 2 as seen from the left of the said figure Fig. 4 is a fragmentary, detail, sectional view of a portion of the cylinder illustrating the interior construction thereof and,
Fig. 5 is a detail plan viewof one of the 7 water receiving buckets or pans which are mounted within the cylinder for receiving the water extracted from the pulp and discharging it through the hollow central shaft.
In the said drawings the numeral 10 indicates the tub or trough of a well-known type of beating engine which is provided with the interior partition or Wall 11 forming a substantially elliptical chamber 12. Mounted within one side'of this said chamber 12 is a'usual beater roll 18 adapted to be rotated in any suitable manner, as by the pulley or gear 14: driven from any suitable source of power, not shown. The said roll 13 and driving means 14 are rigidly connected to a shaft 15 which servesto supply power to the washer drum or cylinder constitutingjthe present invention, all as will appear more fully below.
The present invention comprises a suitable framework 16 which is adapted to be mounted in any suitable manner upon the wallslO' and 11 of the beater 10, preferably on the side thereof opposite to the beater roll 13, as will be clear from Fig. 1. The
said frame preferably comprises two pair of spaced upright members which serve as guides for the slidable bearing blocks 17 in which is rigidly mounted the hollow shaft 18.
The ends of the said shaft 18 are closed, as indicated at 19, and the top portion of f the same is cutaway at suitable points, as indicated at 20, so. that water'which passes through the wire'meshof" the drum or cylinder,pas will .presently appear, may be deposited therein and find its way through the interior thereof to the discharge pipe 21 withwhich one end .of the said hollow shaft is provided. V The said hollow shaft is provided at suitmay be of any suitable construction, but they are preferably made up of a plurality of segments 24, as indicated in Fig. 3, suitably secured together as by the circumferential bands 24; to form acomplete drum.
Each of the said segments is substantially righttriangular incross-section and the comable points withbearing surfaces upon which I aremounted the side'frarnes or members 22 of the washer cylinder 23. These frames ill) stantially 'V-shaped groove in its circumferencefas is clearly shown inFig. 2.
The hypotenuse sides of the triangles, which form thesides ofthe'V,'are covered with wire mesh or cloth 25, while-the altitude sides of the triangle,- which form the outside walls of the complete cylinder, are likewise covered with wire cloth or mesh 26. The bases of thetsaid triangles are adjacent and parallel to the hollow shaft 18 and are left open whereby the water which passes through the interstices of the said wire cloth and into thebuckets or pans to be presently described, may be discharged from the interior of the drum orjcylinder.
The interior of the said cylinder is provided with a plurality of sheet metal buckets or pans2? which are shaped sub stantially as shown in Figs. 4 and 5, and which are adapted to receive the water as it passes through thesaid wire cloth on the side walls of the cylinder and to carry the same upwardly to a point above theh'ollow shaft 18 in which it is discharged. From the said shaft l8 the water may escape through the discharge pipe 21, as willbe readily understood.
The wire screening 26 upon the vertical side walls of the cylinder may be reinforced by means of suitable slats or bars 28, see Fig. 3, and if desired, similar reinforcing members may be employed upon the inclined sides of the V-fshaped groove to support the wire cloth members'.
The bearing b1ocks'17, as above stated, are
slidably mounted inthe upright frame mem bers'16 and they are connected by means of a suitable ropeorcable 29 to a revolving drum or Windlass ,I 30 carried by the upper horizontal member 31 0f the jfram6 16. .The
said drum or Windlass 30 maybe actuated" 'by a worm 32 engaginga worm wheel 88,
which worm gearing may be controlled by means ofthe shaftfitand hand Wlie1f35for a hand adjustment, although it is obvious that, if 'desired, the mechanism just described maybe connected to thepowersha of the beater'for power actuation.
The cylinder 23 may be'ldriven in any suitable manner, as for example by "thegear 36 which is rigid with a sleeve 371 connected to. the said cylinder 23, andthe gear"36 may be rotated-by meansof a pinion'gearj38 carried by a stub shaft 89 driven by means of a belt connection 40 from a counterfshaft 41 which in turn is driven by a belt or gear connection 42 from the shaft 15, which carries the beater roll 13.
In operation the cylinder 23 is lowered by means of'the Windlass 30 to occupy its low ermost position within the trough. or chamber'12 .of the beater 10, and upon operation itsV-sl aped surface compresses and squeezes the pulp'thereby'causing the water carrying thesame to pass through the holes of the wire cloth and into the interior of the said cylinder, where it is caught in the buckets 27, carried downwardly, and discharged into tegration or it may be Withdrawn from the chamber 12 for the nextstep in the paper making process.
The water necessary for carrying on the operation of the machineis supplied to the pulp atany suitable point as is customary in operating" this class of machine.
It will thus be seenthatthis invention provides a washer roll which rapidly and effectively segregates the water from the pulp and discharges it through-the hollow shaft 18 into the discharge pipe 21. 'Furthermore, due to the peculiar construction of the washer roll or cylinder, it provides a relativelylarge surface so that larger. quantities of pulp may be acted upon at a given time and-at a givenspeed than with the previous devices of this character.
Should it, for any reason, be desired to render the Washer roll inoperative, it may be lifted. entirely out ofethe beater trough by manipulating the indlass '30 through the E52 and 33.
It is obvious that those skilled in the art may vary the details of construction, as well as the arrangement of parts without departing from the spirit of the invention, and therefore it isnot Wished to'belimite'd to the above disclosure except as may be required by the claims.
lVhat is'claimed is:
l. A-pulp Working apparatus comprising a support, a'hollow' shaft mounted in said support, a foram-inous cylinder formed from a plurality of segments, triangular in cross section rotatably mounted 011 said shaft and provided with a circumferential groove about its periphery, means for rotating said cylinder, and means for transferring ,water passing to the interior of said cylinder to said hollow shaft.
"2. pulp working apparatus comprising a support, ahollow shaft slidably mounted in said support, a foraniinous cylinder rotatably mounted on said .shaft,.sai;d cylinder comprising a-plura-lity of segments, triangu: lar in cross section, an'darrange'd to form a relatively deep V-sh'aped. groove about the periphery of the cylinder, means forrotating the cylinder, and means comprising a plurality of receptacles, for transferr ng water passing to the interior of said cylinder to said hollow shaft.
3. In a pulp Working apparatus the combination with a beater having a beating chamber and a beater roll rotatably mounted in said chamber, of a foraminous washer cylinder also rotatably mounted in said chamber; the said Washer cylinder being formed of a plurality of segments, triangular in cross section to provide a circumferential groove about its periphery; and connections between said beater roll and said washer cylinder for rotating the latter.
