Abstract
Treatment tools for the mechanical treatment of high-consistency fibrous material, and preferably for dispersing waste paper. The treatment tools are provided with teeth and are moved past one another with tight spacing so that the fibrous material disposed between treatment tool may be subjected to high shearing forces. Because of the intense loading of the teeth, the teeth may be arranged together in groups. The groups utilize at least one intermediary piece positioned between adjacent teeth to form at least a corresponding closed gap between the adjacent teeth of the treatment tools. As a result, a higher mechanical strength of the teeth is achieved and a large through flow area is offered for the material to be treated.
Claims28
A device for the mechanical treatment of high-consistency fibrous material including at least two treatment tools that can be moved in relation to each other, the at least two treatment tools each have a substantially rotationally symmetrical base body and are disposed coaxial to each other and comprise:
- a plurality of fibrous material dispersing teeth disposed in annular rows concentric to centers of each of the treatment tools;
- the plurality of fibrous material dispersing teeth including gaps disposed between adjacent teeth to form clear cross sections, the gaps enabling fibrous material to be treated to flow therethrough;
- annular empty spaces positioned between the annular rows of teeth on each treatment tool;
- the treatment tools engaging with one another such that at least one annular row of teeth of a first treatment tool is positioned within a corresponding annular empty space of a second treatment tool;
- a connecting device that connects at least two adjacent teeth of a row and that forms at least a part of a closed gap comprising a closed cross section that can be flowed through radially;
- and
- a fibrous material compressing and feeding device coupled to an axis of the two treatment tools, wherein the fibrous material is compressed into a plug prior to being fed to the two treatment tools.
A device for mechanically treating a high-consistency fibrous material comprising:
- first and second fibrous material treatment tools, said first and second fibrous material treatment tools mounted for relative rotation;
- each fibrous material treatment tool comprising a plurality of annular toothed rows, each said annular toothed row comprising a plurality of teeth and an adjacent gap between each of said plurality of teeth;
- and
- at least one intermediary piece connecting adjacent teeth to form a closed gap, the closed gap enabling the fibrous material to move through said device;and
- a fibrous material compressing and feeding device coupled to an axis of the two treatment tools, wherein the fibrous material is compressed into a plug prior to being fed to the two treatment tools.
