    摘要: A washing apparatus for processing and cleaning highly contaminated fibrous suspension made from waste paper and containing a high proportion of lightweight contaminants such as foils. The apparatus includes a generally circular rotation chamber and a good half-stuff chamber separated from the rotation chamber by a substantially planar strainer. A revolving rotor is fitted within the rotation chamber in front of the strainer. An entry chamber for receiving fibrous suspension in washing water communicates with the rotation chamber. The entry chamber is of a substantially smaller diameter than the rotation chamber and includes a washing water connection. A waste matter extraction line leads off from the rotation chamber.

    摘要: A system for wastepaper processing which uses a newly developed wash filter of a simple design. The wash filter includes a generally round agitating space and an accepted stock space. The accepted stock space is separated from the agitating space by an essentially flat screen. An agitating wheel is positioned within the agitating space and in front of the flat screen. An entrance space for receipt of fibrous suspension and wash water is also included in the wash filter. The entrance space has a smaller diameter than the diameter of the agitating space. Flow of the suspension from either a primary pulper or a secondary pulper is received in the entrance space of the wash filter. A tailing removal line is in communication with and extends from the agitating space of the wash filter.

    摘要: A method of processing recycled paper which contains such a high amount of wax, hot melts or stickies that they would be expected to cause a stoppage of the paper-manufacturing machine. The paper to be recycled is pulped in a pulper and passed on to respective subsequent stages which include a despecker, grader and hydrocyclone. Pulping takes place at a temperature of at least 60.degree. C., and at the same time subjects the paper to a high shear action. The processing line includes a pulp-thickening stage, preferably after the processing stages mentioned, in order to separate off a very high proportion of the wax, hot melts and stickies finely dispersed in the pulper.

    摘要: A method of digesting waste paper is disclosed wherein waste paper is digested in a gas-tight container at an elevated pressure supplied by compressed gas introduced to the container. The digestion mixture is circulated within the pulper by a rotor having vanes or helical surfaces.
