SEPABATOR FOR PAPER-PULP.
Specification of Letters Patent.
Patented Mar. 9, 1920.
Application filed March 22, 1919. Serial No. 284,439.
vide a separator for paper pulp which will effectually open up or separate the bunches of fibers, so thatthe fibers may more easily part with any undesirable matter that may adhere to them before they reach the strainer or wire of the paper making machine.
The invention is illustrated in the accompanying drawing in which Figures 1 and 2 are sections at right angles to one another showing a construction including a liquid spraying device, Fig. 1 being a section on the line ab, Fig. 2.
As shown, the separator comprises a vat or chest 1 in which the separating operation takes place, said vat being divided into compartments 2 by substantially vertical or inclined fixed or upstanding and depending partitions or sluices 3 and 3, respectively, the direction of flow of the pulp being alternately downward and upward, whereby the lighter undesirable matters may be retained at the upper level of the vat by upstanding partitions 3, while the heavier undesirable matters settle by gravitation and may pass into a chamber or chambers 4: below the vat.
Preferably a transparent plate 6 .is fitted at the most convenient position to permit the accumulation of refuse matters to be observed.
There 1s lncorporated 1n the separator a scouring device comprising arwater spray pipe 19 the jets issuing from each of which impinge against the upper edge of the adjacent partition 3, such edge. being beveled and serrated.
e What I claim is 2- 1. A separator for paper pulp comprising a vat, upstanding and depending partitions dividing said vat into compartments, said partitions so arranged that the path of pulp flowing through said vat is alternately downward and upward, said upstanding partitions formed with beveled edges and means for directing jets of fluid on to the pulp passing over said edges.
2. A separator for paper pulp comprising a vat, upstanding and depending partitions dividing said vat into compartments, said partitions so arranged that the path of pulp flowing through said vat is alternately downward and upward, whereby lighter undesirable matters are retained by the upper edge of an upstanding partition at the upper level of the vat and heavier undesirable matters are brought to the bottom of said vat, and a transparent inspection plate adjacent to the bottom of said vat.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
, JOHN WHITE.
