Description

Einrichtung zum Auflösen von Altpapier u. dgl. Die Erfindung betrifft eine Einrichtung zum Auflösen von Altpapier u.dgl., bestehend aus einem Kollergang, einer Siebvorrichtung und einem Zerfaserer in Hintereinanderschal-' tung unter Benutzung eines Kollergangs, dessen Schüssel an einer Stelle des Bodens außerhalb der Mahlbahn durchbrochen und mit einem die Durchtrittsmenge des zerkleinerten Gutes regelnden Schieber versehen ist. Die Erfindung bezweckt eine erhebliche Steigerung der Durchsatzmenge unter gleichzeitiger Vereinfachung der Anlage und des Betriebes. Dies wird erfindungsgemäß dadurch erreicht, daß .dieDurchbrechungen des Schüsselbodens als Schlitze ausgebildet sind, deren Längsachsen in einem Winkel zum Schüsselradius stehen. Bei den bekannten Einrichtungen der eingangs beschriebenen Art wird der Durchsatz im wesentlichen von der Leistung des Kollergangs bestimmt, die zufolge des unstetigen Betriebes weit hinter jener des Zerfaserers zurückbleibt, so daß entweder auf Vorrat gekollert werden muß oder mehrere Kollergänge nebeneinander betrieben werden müssen. Benutzt man an Stelle des unstetig arbeitenden Kollergangs einen an sich bekannten, stetig arbeitenden, dessen Schüssel an einer Stelle des Bodens durchbrochen und mit einem die Durchtrittsmenge des zerkleinerten Gutes regelnden Schieber versehen ist, dann zeigt sich alsbald ein erheblicher Leistungsrückgang, der durch die besondere Beschaffenheit des Kollergutes, nämlich Altpapier u. dgl., begründet ist, das im Gegensatz zu anderem, nicht Faserstoff enthaltendem Rohgut ein rasches Zusetzen der lochförmigen Durchbrechungen der Kollergangsschüssel verursacht. Dadurch, daß dieDurchbrechungen in Form von Schlitzen ausgebildet werden, derenLängsachsen einen Winkel mit dem Schüsselradius bilden, wird ohne besondere Maßnahmen- ein dauerndes gleichmäßiges Austreten des zerkleinerten Gutes, und zwar ohne erhebliche Beimengungen gröberer Stücke, gesichert.Device for dissolving waste paper and the like a device for dissolving waste paper and the like, consisting of a pan mill, a sieve device and a shredder in series connection using a pan mill whose bowl is at a point on the floor outside of the grinding path broken through and with a regulating the amount of passage of the shredded material Slide is provided. The invention aims to significantly increase the throughput while at the same time simplifying the system and operation. This is according to the invention achieved in that .the openings in the bottom of the bowl are designed as slots whose longitudinal axes are at an angle to the bowl radius. With the known Devices of the type described above, the throughput is essentially determined by the performance of the pan mill, the result of the discontinuous operation remains far behind that of the shredder, so that either rolled in stock must be or several pan mills must be operated next to each other. Used instead of the discontinuously working pan mill, one is known per se, continuous working, whose bowl is perforated at one point on the bottom and with a the flow rate of the comminuted material is provided regulating slide, then There is soon a significant drop in performance, due to the special nature of the milled goods, namely waste paper and the like, is justified, which in contrast to other, Raw material that does not contain fiber causes rapid clogging of the perforated openings caused by the pan pan. In that the perforations in the form of Slots are formed whose longitudinal axes make an angle with the radius of the bowl without special measures, becomes a permanent, uniform one Exit of the comminuted material, without substantial admixtures of coarser pieces, secured.

In der Zeichnung ist die Einrichtung gemäß derErfindung dargestellt, und zwarzeigt Fig. i einen Aüfrlß und Fig.2 einen Grundriß.In the drawing the device according to the invention is shown, namely Fig. 1 shows a plan view and Fig. 2 shows a plan.

a bezeichnet die Kollergangschüssel, b die Läufersteine. c eine im Schüsselboden außerhalb der Mahlbahn eingelassene Schlitzplatte, deren Schlitzei mit dem Schüsselradius einen Winkel bilden. Unterhalb der Schlitzplatte befindet sich ein einstellbarer Schieber zur Regelung der Gutclurchtrittsmenge. h bezeichnet einen an der Königswelle starr befestigten, dicht über dem Schüsselboden angeordneten Streichschaber, der zweckmäßig möglichst schmal (etwa 5 cm hoch) gehalten wird und dazu dient, die Schlitzplatte durchlässig zu halten. d bezeichnet ein Becherwerk. (las den gekollerten Stoff auf das Schüttelsieb f fördert, das die Aufgabe hat, größere Gutstücke sowie Fremdkörper zurückzuhalten und noch verwertbare Papierstücke über die Rinne j in den Kollergang a zurückzuführen. e bezeichnet einen Zerfaserer üblicher Art, z. B. nach Wurster. Wie üblich, wird das Altpapier o. dgl. in durch Wasser oder Dampf aufgeweichtemZustand im Kollergang zerkleinert.a denotes the pan pan, b the runner stones. c a slotted plate embedded in the bottom of the bowl outside of the grinding path, the slotted egg of which forms an angle with the bowl radius. Below the slotted plate there is an adjustable slide to regulate the amount of material that passes through. h denotes a scraper that is rigidly attached to the vertical shaft and arranged close to the bottom of the bowl, which is expediently kept as narrow as possible (about 5 cm high) and serves to keep the slotted plate permeable. d denotes a bucket elevator. (read the crumbled material conveyed to the vibrating sieve f, which has the task of holding back larger pieces of material and foreign bodies and returning usable pieces of paper via the channel j to the pan a Usually, the waste paper or the like is shredded in a pan softened by water or steam.
