Abstract
10,229. Petsche, B. W. April 26. Pulp, preparation of. - In the recovery of pulp from waste papers, such as newspapers, books, &c., the material is disintegrated in the usual way in the beating- engine, soaked for about two hours in an alkaline solution containing 1 part of caustic soda in 1,000 parts of water, and then pumped into a trough A, whence it flows on to a coarse screen E under slanting streams of water from nozzles a, the inclination of which may be adjusted. The coarse stock and foreign coarse substances flow over the screen E to a gutter and are delivered to a settling-tank D. The pulp passes through the screen and is conveyed to the fine screen F. Under the action of similar nozzles b, the impurities, such as particles of ink, pigments, size, filler, &c., are separated from the fibre and are drawn through the screen and collect in the bottom of the trough C from which they pass out through the opening c into the trough D. The purified pulp is carried over and collected in the trough I. To regulate the rate of flow of the pulp, and therefore its purity, the screen F is hinged at y and may be raised or lowered by chains p to alter its inclination. The water pipe W<1> is hinged at Z, and its inclination may be altered to correspond by chains p'. The clarified water from the tank D can be used again for the beating-engine. The pulp recovered by this process may be used for print papers, pulp boards, the surfacing of chip and straw boards, and combination and coated boards.
