    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 present invention serves for loading a pulp suspension (S) with calcium carbonate. Liquid calcium hydroxide as milk of lime (7) is added during or before the pulp operation (1) carried out to form the pulp. By introducing gaseous carbon dioxide (8) into the pulp suspension thus treated, a chemical reaction is triggered therein, in which the finely divided calcium carbonate is precipitated. The present invention is particularly economic and effective due to the early addition of calcium oxide or calcium hydroxide.

    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.
