Gegenstand der Erfindung ist ein ununterrochen arbeitender Darr- und Verkohlungsifen, welcher in bekannter Weise aus einer größeren Anzahl parallel nebeneinanderstehender und abwechselnd oben und unten miteininder verbundener Schächte gebildet wird. )urch letztere wird das zu behandelnde Gut η zickzackförmigem Laufe mittels endloser etten hindurchgeführt. Dieser Ofen ist lauptsächlich für die Behandlung von Briketts, i'obei die Luft fernzuhalten ist, bestimmt, tn besonderen für das Verfahren gemäß 'atent 158497, aus Kohlengrus unter Anwendung wasserlöslicher Bindemittel durch ^rerkohlung der letzteren wetterbeständige 'riketts herzustellen. In Berücksichtigung er ihm dabei überwiesenen Aufgabe, die Verohlung des Bindemittels ohne Entflammung es Kohlengruses zu veranlassen, weicht der orliegende Ofen von den bisherigen ähnlichen fenausführungen, weiche vorwiegend nur im Trocknen bestimmt waren, in der Hauptiche dahin ab, daß eine Luftströmung durch :inen Innenraum nicht erfolgt, der Zutritt )n atmosphärischer Luft zu jenem Raum jerhaupt möglichst verhindert ist und die riketts im Ofen selbst, also unter Luftab-Ihluß vorgewärmt und auch wieder abgekühlt lirden. Der vorliegende Ofen entbehrt da- »ufhin jegliche Luftzuführungs- und Ab-The subject of the invention is an uninterrupted kiln and charring soap, which is formed in a known manner from a larger number of parallel adjacent and alternately connected shafts above and below. ) The material to be treated is passed through the latter in a zigzag shape by means of endless chains. This furnace is lauptsächlich for the treatment of briquettes, is to keep the air i'obei determined, tn particular for the process according 'atent 158497, from coal slack, using water-soluble binder by ^r erkohlung the latter weather-resistant' to produce riketts. In consideration of the task assigned to him, to cause the charring of the binding agent without igniting the coal burrs, the present furnace differs from the previous similar furnace designs, which were mainly intended only for drying, in the main one that an air flow through: the interior does not take place, the access of atmospheric air to that room is prevented as far as possible and the rikettes in the furnace itself, that is, preheated and also cooled again in the absence of air. The furnace at hand then lacks any air supply and exhaust

führungseinrichtungcn und die zur Erzeugung und Regelung von Luftströmungen erforderlichen Ventilatoren, Schieber und dergl. Der zum Verkohlen des Bindemittels erforderliche Hitzegrad wird einzig in wenigen Mittelschächten dieses Orens — und darin besteht die Erfindung — hervorgerufen, während in den nicht beheizten, aber in ununterbrochener Verbindung mit den Mittelräumen bleibenden Seitenschächten die Vorwärmung und Darrung des Gutes erfolgt. Innerhalb des Ofens kann also durch entsprechende Länge des Weges, den das Gut zu machen hat, eine solche Abkühlung der Masse aui dem Wege zur Ausgangsöffnung erzielt werden, daß die Entnahme des fertigen Produktes an dieser Stelle anstandslos von Hand erfolgen kann und seine sofortige Verladung ermöglicht ist.
\ Am der Zeichnung ist ein solcher Ofen durch'Fig. ι im Längsschnitt nach χ -χ und Fig. 2 im Horizohtalschnitt nach y-y schematisch zur Darstellung gebracht.Führungseinrichtungcn and the fans, sliders and the like required for generating and regulating air flows. The degree of heat required to char the binding agent is only generated in a few central shafts of this oren - and this is where the invention consists - while in the unheated, but in uninterrupted connection with In the side shafts that remain in the middle, the goods are preheated and dried. Within the furnace, a corresponding length of the path the goods have to make can be used to cool the mass on the way to the exit opening, so that the finished product can be removed by hand at this point without any problems and its immediate loading is possible is.
\ On the drawing such a furnace is durch'Fig. ι in the longitudinal section according to χ -χ and Fig. 2 in the horizontal section according to yy is shown schematically.

Er "setzt sich in bekannter Weise aus einem in diesem Fall in doppelter Breite der Seitenschächte gebildeten Mittelschacht α und einer größeren Anzahl von in geringerer Höhe gebildeten Seitenschächten b zusammen, welche abwechselnd oben und unten verbunden sind, so daß ein zusammenhängender zickzack- förmigcr Weg für das Gut gebildet wird.It "is made up in a known manner of a middle shaft α formed in this case twice the width of the side shafts and a larger number of side shafts b formed at a lower height, which are alternately connected above and below, so that a coherent zigzag-shaped path for the good is formed.

The two end shafts open into a channel c located below the bottom common to the other chambers, which is just as wide as the chambers. Along this S channel and through the chambers, the carrier baskets d with the material to be treated are guided in a closed row while maintaining a certain distance from one another. They are suspended in a known manner on the horizontal connecting axes e of two endless link chains / pendulum, which are arranged inside or outside the furnace near its two longitudinal walls and are guided by line rollers g and a tensioning roller h located in the middle of the channel c during their forward movement Arrange baskets through the zigzag interior of the oven.

The heating of the goods to the required

By stringing together a corresponding number of cooling chambers, the degree of this cooling can be brought to the point where the substance, after exiting the last chamber and after being guided through space c, is removed from the loading point Ic, which is located just above the latter in the first preheating channel so, low temperature has assumed that it can be removed by hand and come immediately for loading and shipping without further refrigeration required for it. , '
