Description

Vorrichtung zum Verschwelen asphalthaltiger Brennstoffe Das Hauptpatent 679 707 betrifft eine Vorrichtung, um asphalthaltige Brennstoffe und Hydrierungsrückstände in außen beheizten umlaufenden, mit Mahlkörpern versehernen Trommeln zu verschwelen, wobei als Mahlkörper kantige Hohlkörper dienen.Device for carbonizing asphalt-containing fuels The main patent 679 707 relates to a device for carbonizing asphalt-containing fuels and hydrogenation residues in externally heated rotating drums provided with grinding media, with angular hollow bodies serving as grinding media.

Die hohlen Mahlkörper jedoch halten bei ununterbrochenem Dauerbetrieb den Einflüssen der Temperatur und der Mahlarbeit nicht stand, so daß sie nach einigen Monaten durch neue Körper ersetzt werden müssen.The hollow grinding media, however, hold up in uninterrupted continuous operation the influences of the temperature and the grinding work did not stand, so that after some Months have to be replaced by new bodies.

Es wurde nun gefunden, daß man die Nachteile dieser Hohlkörper und gleichzeitig die Nachteile der in der Technik gebräuchlichen schweren, massiven Körper dadurch vermeidet, daß man verhältnismäßig dünnwandige Gußstücke hoher Festigkeit herstellt, bei welchen die schabenden Kanten gegeneinander versetzt sind. Dadurch ergibt sich der weitere Vorteil, daß die Körper sich im Betrieb selbst vom angesetzten Koks reinigen, indem die schabenden Kanten wie die Zähne zweier Zahnräder ineinander,-reifen können. Beispielsweise verwendet man Gußkörper der in der Zeichnung gezeigten Form und als Baustoff hierfür Gußeisen von der Zusammensetzung von 2,8 % C, o,9 % Si und o,7 Oilo Mn, in welchem der Kohlenstoff im wesentlichen in Form von Zementit vorliegt. Dieses ergibt bei geeigneter Herstellungsweise Körper mit einer Brinellhärte von ¢oo bis 450 Einheiten, die trotzdem noch zäh genug sind, um unter den Betriebsbeanspruchungen nicht zu zerbrechen.It has now been found that the disadvantages of these hollow bodies and at the same time the disadvantages of the heavy, solid bodies customary in the art are avoided by producing relatively thin-walled castings of high strength in which the scraping edges are offset from one another. This has the further advantage that the bodies clean themselves of the coke that has settled in during operation, in that the scraping edges can interlock like the teeth of two gearwheels. For example, castings of the shape shown in the drawing are used and the building material for this is cast iron with a composition of 2.8 % C, 0.9% Si and 0.7 O Mn, in which the carbon is essentially in the form of cementite. With a suitable production method, this results in bodies with a Brinell hardness of ¢ oo to 450 units, which are nevertheless tough enough not to break under the operational stresses.
