Description

Verfahren zur Darstellung von Karbid im kontinuierlichen Betriebe.
Das übliche Verfahren bei der Herstellung von Karbid besteht darin, dass eine Mischung von gebranntem Kalk mit Kohle u. dgl. in einem Schmelzofen bei hoher Hitze zum Schmelzen gebracht wird.
Die Beschaffenheit des gebrannten Kalkes wechselt, je nachdem derselbe aus grösseren oder kleineren Kalksteinstücken oder aus einer Mischung beider hergestellt wird. Wenn der ge- hrannte Kalk noch kohlensauren Kalk enthält oder nach längerer Lagerung Kohlensäure aus der Luft aufgenommen hat, so wirkt die Kohlensäure sehr nachteilig beim Schmelzverfahren, da Kohlensäure den Schmelzprozess unterbricht und Veranlassung zur Verstopfung des Schmelzofens gibt.
Das Zerkleinern des gebrannten Kalkes erzeugt einen Staub, der schädlich auf die Lungen der Arbeiter und selbst auf die Vegetation in der L'umgebung der Anlage wirkt.
EMI1.1
best geeigneter Beschaffenheit mit der beim Brennen des Kalksteines aufgespeicherten Hitze in einem vorzugsweise elektrischen Schmelzofen zu Karbid zu verarbeiten.
Die beiliegende Zeichnung zeigt in schematischer Weise eine zur Ausführung des Verfahrens

Magnesium und chlorsaurem Kali besteht.
PATENT. ANSPRüCHE :
1. Verfahren zur Darstellung von Karbid im kontinuierlichen Betriebe, dadurch gekennzeichnet, dass der für das Kalkkohlegemisch erforderliche kohlensaure Kalk in gepulvertem Zustande, mit gepulvertem Brennmaterial gemischt, zunächst in einem kontinuierlich geheizten Brennofen zur Behandlung gelangt, dass'hierauf die gar gebrannte Ofenbeschickung im heissen Zustande in einem Mischapparat geleitet, daselbst mit vorgewärmter entgaster Kohle gemischt und diese Mischung den eigentlichen Schmelzöfen der Anlage zugeführt wird.

Process for the preparation of carbide in continuous operation.
The usual method of making carbide is to use a mixture of quick lime with coal and the like. Like. Is brought to melt in a melting furnace at high heat.
The nature of the quicklime changes, depending on whether it is made from larger or smaller pieces of limestone or from a mixture of both. If the burnt lime still contains carbonate of lime or has absorbed carbonic acid from the air after a long period of storage, the carbonic acid has a very disadvantageous effect on the melting process, since carbonic acid interrupts the melting process and causes the furnace to clog.
The crushing of the quick lime creates a dust which is harmful to the workers' lungs and even to the vegetation in the vicinity of the plant.
EMI1.1
the most suitable quality to process into carbide with the heat accumulated during the burning of the limestone in a preferably electric melting furnace.
The accompanying drawing shows in a schematic manner one for carrying out the method
EMI1.2

EMI2.1
Magnesium and Potash Chlorate consists.
PATENT. Expectations :
1. A method for the preparation of carbide in continuous operation, characterized in that the carbonate of lime required for the lime-coal mixture in powdered state, mixed with powdered fuel, is first treated in a continuously heated kiln, that'hierauf the burnt kiln charge in the hot The condition is passed in a mixer, there mixed with preheated degassed coal and this mixture is fed to the actual melting furnace of the plant.
