PULP-WASHING MACHINE.
SPECIFICATION forming part of Letters Patent N 0. 685,594, dated October 29, 1901. Application filed April19, 1901. SeriaiNo. 56,539. (NomodL) To all whom it may concern:
Be it known that I, FRANK A. FRANKLIN, a citizen of the United States, residing at Shelton, in the county of Fairfield and State of Connecticut, have invented a new and useful Improvement in Pulp -Washing Machines, of which the following is a specification.
My invention relates to a revoluble cylindrical device adapted for receiving pulp-stock or finely-ground paper-stock for the purpose of washing therefrom impurities. rial is fed into this revoluble cylindrical device and is repeatedly turned over and over with the rotation of the said device, and water is delivered upon the commi'nuted pulp or finely-ground paper-stock as the same is turned over and when the said material reaches the delivery end of the said cylindrical device the impurities are presumably completely washed from the said paper-pulp or paper-stock.
In my present invention I provide the rev oluble cylindrical device with ring-like heads supported on pairs of wheels on companion shafts, to one ofwhich shafts power is applied for rotating the cylindrical casing. I also prefer to employ one or more intermediate rings, and the said casing is built up of the ring-like heads and the intermediate ring or rin gs, together with spacing-apart devices, longitudinal tie-rods, a wire-cloth inclosure, tying-wires for connecting the inclosure to the spacing devices, and supporting wires surrounding the entire cylindrical casing. The casing is set at an inclination,and a stationary water-supply pipe passes longitudinally through the same. The material is delivered into the higher end and finds an exit from the opposite or lower end, and as the cylindrical casing revolves the material is turned over and over and water is delivered thereon to wash therefrom the impurities.
In the drawings, Figure 1 is a vertical longitudinal section broken across at two points, so as to show the respective ends and the central portion. .Fig. 2 is a cross-section of the same, the section Fig. 1 being taken on thedotted line a: at of Fig. 2. Fig. 3 is an enlarged sectional view through V the ringlike heads and the intermediate ring to show The matethe spacing tubes and tie rods connecting the parts. Fig. 4. is an enlarged elevation of a portion of a spacing-tube and tie-rod with a part of the wire-cloth inclosure and showing the tying wires and supportingwires. Fig. 5 is a cross-section of the parts shown in Fig. 4. and on the same scale, and Fig. 6 is a cross-section showing a portion of the revoluble cylindrical casing with a modified disposition of the water-supply pipe.
With reference to Figs. 1 to 5, inclusive, of the drawings, the revoluble cylindrical device or casing comprises the end ring-like heads a I), having flat peripheries and flanged open centers. I Y
'0 represents an intermediate ring of corresponding diameter to the ring-like heads a b. Between the respective headsa b and intermediate ring 0 I employ spacing-tubes d, circumferentially equidistant and in groups of corresponding length between the head a and ring 0 and the head Z) and ring 0, and tie-rods '6 pass through the spacing-tubes, the, heads a b, and ring 0, with nuts 1 on the ends of the tie-rods against the outer faces of the ringheads a, b, by means of which tension is applied to the tie-rods to draw the heads toward one another and hold the spacing-tubes firmly against the opposite faces of the ring-like heads and intermediate ring, as shown in the enlarged Fig, 3, whereby the said parts are firmly connected. v
Wire-cloth f extends around outside of the spacing-tubes d, between the respective heads and ring, forming acomplete cylindrical inclosure, and I prefer to employ arc-plates 2, extending along the outer surface of the wirecloth and over the spacing-tubes, and tyingwires 3, passing through the wire-cloth around the tie-rods e and over the arc-plates 2 at intervals, so as to hold the wire-cloth inclosure firmly to the spacing-tubes. To prevent the wire-cloth inclosure saggingin the use of'the 7 machine, I prefer to make'use of circumferential supporting-wires 4, that extend entirely around outside of the wire-cloth and i the arc-plates at desired intervals, so as to support the cloth between the tubes d and prevent the same sagging under the weight of'material within being treated.
\Vheels g g g in pairs are supported upon companion shafts 72. h h in suitable bearings at the end and central supporting-frames 2' 2' i, and one of said shafts is driven by the pulley 5 to rotate the cylindrical device. These wheels are preferably flanged to receive the ring-like heads a b and intermediate ring 0, and the cylindrical casing and the shafts h are placed at an inclination, so as to cause the material to feed by gravity, and I employ an inclined trough k beneath the shafts and wheels and the cylindrical casing, so as to catch the washing-water falling from the cylindrical casing as the pulp-stock or finelyground paper-stock is being washed, and a gutter Z, running along one side of the inclined trough, serves to collect and deliver the waste-water.
The supply-pipe 6 extends into the higher ring-like head a, for delivering the pulp-stock or finely-ground paper-stock within the easing, and a discharge-way 7 comes up to and beneath the edge of the ring-like head I) at the lower end to receive and deliver the pulpstock or finely-ground paper-stock as it passes out of the cylindrical casing. A water-pipe 8, suitably supported, passes through the easing and is perforated on the under side for its entire length within the casing for delivering water upon the pulp-stock or paperstock for the purposes of washing therefrom the impurities during the gravity transit of said material through the casin g. This pulpstock with the rotation of the cylindrical casing in the direction of the arrow turns over and over, and the agitation caused thereby comminutes the material into small masses, which remain largely upon one side, and the perforations in the pipe 8 are so placed (see Fig. 2) as to deliver the water directly upon the material.- This pipe is suitably supported at its ends, and instead of passing directly through the center of the casing, as shown in Figs. 1 and 2, it may pass in and be bent into the position shown in the modification, Fig. 6, and from the pipe in this position the Water will fall directly upon the material instead of at an inclination, as will be the case where thepipe is central.
My improvement comprises a strong, substantial, yet very simple and efficient structure and one capable of fully and completely carrying out the objects intended.
