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： Waste paper is chemically and mechanically treated to pulp it into a stock. The waste paper is tumbled, without mechanical beating and without rotary means likely to become fouled by foreign material mixed with the paper. A chemical pulping liquid is mixed with the paper as it is being tumbled. The resulting tumbled, pulped waste paper is delivered to a reaction tower where it is further chemically pulped. The waste paper is removed from the bottom of the reaction tower. Various embodiments of paper tumbling devices are disclosed including a rotating drum, stepped conveyor belts, stepped rollers, a vibratory conveyor and a tumbling tower with baffle plates along its length. The reaction tower has an adjustable sized outlet opening at its bottom. An appropriate conveyor is insertable through the outlet opening of the reaction tower for extracting pulped paper stock.

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： The disclosure concerns a method and apparatus for producing a suspension of fibrous material from waste-paper. Following dissolving the waste-paper, cleaning the dissolved suspension and stain removal, the suspension is floated in series of flotation cells. The suspension is first floated through a first series of flotation cells. Thinning liquid medium, such as water, is added to the suspension. It is then floated through a second series of flotation cells. In one embodiment, the cells of the second series are larger than the cells of the first series. Following the second series of cells, the material floated from the second cells is delivered to another cell. In another embodiment, the cells of the second series are themselves divided into two separate rows of cells and the suspension is divided among the rows of second cells. In this embodiment, following flotation through the second cells, the material floated from the second cells is next delivered to joint secondary cells.

摘要： A flotation tank which is elongate and is divided along its length into individual compartments. Injectors (2) for each compartment are connected laterally to the tank (1) approximately 30 cm to 50 cm below the surface of the suspension so that the suspension flows out in a forward direction towards the outlet end and scum removal trough (3) of the flotation tank (1). The injectors are preferably connected both at their inlet side and their outlet side to the same compartment. The removal of scum is preferably effected by means of cyclones which are provided in a vertical arrangement at the outlet end of the flotation tank.
