摘要： The disclosure concerns a process and an apparatus for recovering fiber suspension from a mixture of different types of waste paper. The waste paper is disintegrated in a pulper to form a fiber suspension comprised of individual fibers. After perhaps passing a presorting device, the fiber suspension passes through a sorting device which separates the fibers into a long-fiber fraction and a short-fiber fraction. The two fractions are subsequently treated in different ways, generally for the purpose of cleaning the fiber fractions. Various treatment techniques are disclosed, including separating impurities from the long-fiber fraction by flotation and/or bleaching the long-fiber fraction and washing the short-fiber fraction and/or treating it by flotation for de-inking the short-fiber fraction and perhaps thereafter sorting the short-fiber fraction to remove impurities.

摘要： Waste paper is fed into a horizontal drum and therein treated with suitable liquids to form pulp. A magnetic device is disposed adjacent one side of the drum to produce a magnetic field along one arcuate section and extending from the upper portion toward the bottom thereof. Magnetic particles mixed with the paper are carried by said arcuate section of the drum by virtue of the influence of the magnetic field until they reach the top where they leave the field and then fall downwardly into an inclined trough from which they gravitate to the exterior of the drum. Pulp is concurrently discharged from the drum.

摘要： Water used in the treatment of waste paper is now commonly re-cycled. Hard water is required for such processes. For maintaining the hardness of the water, the re-cycled water is hardened by dissolving calcium carbonate and carbon dioxide in it, thereby forming calcium bicarbonate. An apparatus for hardening the water comprises a mixing container with inlets for waste water, carbon dioxide, and calcium carbonate, and with outlets for foam, hardened water and undissolved calcium carbonate.

摘要： The invention concerns a flotation apparatus for separating impurities, such as printing ink, or the like, from a fiber suspension that has been formed from waste paper. The apparatus includes a container for flotation of the suspension. A drive shaft extends into the container, either from above or below. A feed opening for suspension is defined at the bottom of the container. On the drive shaft is a pump impeller for impelling suspension into the container and downstream along the drive shaft. From the pump impeller there is a rotor located on the drive shaft for dispersing air that is introduced to the container by an air feed conduit which emits air into the region of the rotor. The drive shaft itself may serve as the air feed conduit and it may have air outlets at either or both of the pump impeller and the rotor. A foam withdrawal means for withdrawing the foam of impurities generated in the flotation apparatus has an inlet positioned at the axis of the cylinder which is at the axis of the rotor.

摘要： A process and apparatus for preparing waste paper for reuse in a paper machine. Waste paper, water and de-inking chemicals are introduced to coarse pulping apparatus, and the coarsely pulped stock suspension is then thickened by filtration and treated in a reaction tower. The pulp is then thinned and passed through flotation apparatus to remove separated impurities, particularly printing inks. Water removed from the pulp in the thickening operation is passed through second flotation apparatus with the clean water therefrom being reintroduced to the apparatus.
