Description
Heizvorrichtung für mechanische Röstöfen. Die Erfindung bildet eine Heizvorrichtung für mechanische Röstöfen, die sich von bekannten ähnlichen Vorrichtungen dadurch unterscheidet, daß in der Ofenwand eine Öffnung zur Aufnahme eines porösen, die Ofenkammer nach außen abschließenden Stopfens aus feuerbeständigem Material vorgesehen ist, durch das der Brennstoff durchgetrieben wird und sich auf der Innenseite entzündet.Heating device for mechanical roasting ovens. The invention forms one Heating device for mechanical roasting ovens, different from known similar devices differs in that in the furnace wall an opening for receiving a porous, the furnace chamber to the outside closing plug made of fire-resistant material is provided through which the fuel is driven through and is on the inside ignited.
Die Zeichnung veranschaulicht den Erfindungsgegenstand in beispielsweiser Ausführung. Abb. i zeigt einen Höhenschnitt eines Ofens nach der Erfindung, Abb. 2 und 3 sind Querschnitte nach Linie a-a bzw. Linie b-b der Abb. _.The drawing illustrates the subject matter of the invention in example execution. Fig. I shows a vertical section of a furnace according to the Invention, Figs. 2 and 3 are cross-sections along line a-a and line b-b of Fig. _.
Der in den Zeichnungen veranschaulichte Ofen ist ein Experimentier- oder Laboratoriumsofen mit einer die- Ofenherde führenden rotierenden Welle. Die mit diesen Ofenherden abwechselnd übereinanderliegend angeordneten festen Herde sind an der Ringofenwand befestigt. Diese Anordnung der drehenden und festen Ofenherde bildet jedoch nicht den Gegenstand vorliegender Entfernung.The furnace illustrated in the drawings is an experimental or laboratory furnace with a rotating shaft guiding the furnace hearth. the with these oven stoves alternately arranged one above the other are attached to the ring furnace wall. This arrangement of rotating and fixed ovens however, is not the subject of the present removal.
Nach Abb. i bezeichnet i, ia die Ofenwand. Die rotierende Mittelwelle 2 des Ofens trägt nahe dem oberen Ende ein Schneckenrad 3, welches auf Rollen drehbar auf dem Ofen angeordnet ist. Die hängende Welle 2 trägt kreisrunde Herde q., welche abwechselnd in Aufeinanderfolge mit festen Herden 5 der Ringofenaußenwandung vorgesehen sind.According to Fig. I, i, ia denotes the furnace wall. The rotating medium wave 2 of the furnace carries a worm wheel 3 near the upper end, which rotates on rollers is arranged on the furnace. The hanging shaft 2 carries circular herd q., Which alternately provided in succession with fixed hearths 5 of the ring furnace outer wall are.
Das zu bearbeitende Gut wird zunächst auf dem Dach 6 des Ofens aufgespeichert und dann vermittels Rührarme 7, 72 der Welle 2 durch eine Mittelöffnung des Daches in den Ofen hineingebracht, so daß es von Herd zu Herd nach abwärts sinkt, bis es schließlich von dem untersten Herde nach außen abgeführt wird. Das Beschicken des Gutes über die Herde erfolgt mit Rührarmen 8, welche von dem Ofendach herabhängen, durch von den festen Herden nach abwärts gerichtete Rührarme 9 und durch an den rotierenden Herden befestigte Rührarme io: - Die Ofenwand ist mit Öffnungen ausgebildet, von denen die obersten Öffnungen normalerweise vermittels je eines Stopfens ii verschlossen wird. Die nächsten Öffnungen sind Kontrollöffnungen, in denen durchsichtige Isolatoren 12 vorgesehen sind. Die letzten Öffnungen enthalten die Brenner 14. zum Erhitzen des Gutes. Durch Entfernung der in den obersten Öffnungen sitzenden Stopfen kann man sich freien Zugang zu dem Ofeninnern verschaffen. Die nächsttiefer liegenden Öffnungen dienen, wie bereits erwähnt, zur Kontrolle des in dem Ofen herabsinkenden zu erhitzenden Gutes, während die Brenner in den untersten Öffnungen die erforderliche Hitze für das Gut liefern.The material to be processed is first stored on the roof 6 of the furnace and then by means of agitator arms 7, 72 of the shaft 2 through a central opening of the roof placed in the oven so that it sinks down from stove to stove until it is is finally discharged to the outside from the lowest hearth. The loading of the Good things about the herd are done with agitator arms 8, which hang down from the oven roof, by the fixed herds downwardly directed agitator arms 9 and by to the rotating stoves attached agitator arms io: - The furnace wall is designed with openings, of which the uppermost openings are normally closed by means of a plug ii each will. The next openings are control openings with transparent insulators 12 are provided. The last openings contain the burners 14. for heating of the good. By removing the plugs in the uppermost openings, you can you get free access to the inside of the furnace. The next lower As already mentioned, openings serve to control the sinking in the furnace to be heated, while the burners in the lowest openings provide the required Provide heat for the goods.
jeder Brenner besteht aus einem Gehäuse 13, welches an seinem inneren Ende vermittels eines Stopfens 14 aus feuerbeständigem Material .verschlossen ist, zu dessen äußerer Fläche die Brennstoffzufuhr Zugang hat, so daß unter Druck der Brennstoff durch die Poren des Stopfens hindurchdringt und dadurch so stark erhitzt wird, daß auf der anderen Seite des Stopfens eine Flamme entsteht, die das die Ofenkammer passierende Gut erhitzt. Um eine Explosionsmöglichkeit oder ein Rückschlagen des Gases nach hinten -in. dem Brennergehäuse durch Erhitzung oder Entzündung des Brennstoffes zu verhüten, ist das Gehäuse 13 mit einer Kühlvorrichtung versehen. Diese Kühlvorrichtung besteht aus einem hohlen Gehäuse 15, welches in dem Brennergehäuse sitzt und mit Röhren 16 zur Kühlflüssigkeitszufuhr ausgestattet ist. Das Brennstoffzufuhrrohr 17 läuft durch dieses Gehäuse und führt den Brennstoff in eire Kammer 18, welche zwischen dem Gehäuse vor der Außenfläche des Stopfens 14 angeordnet ist. Durch Regulierung der Heizflamme der Brenner 14 wird der gleiche Effekt wie in einem 141uffelofen erzielt.each burner consists of a housing 13, which on its interior The end is closed by means of a plug 14 made of fire-resistant material, to the outer surface of which the fuel supply has access, so that under pressure the Fuel penetrates through the pores of the stopper and is thus heated so strongly that a flame arises on the other side of the plug, which the furnace chamber passing well heated. To avoid the possibility of an explosion or kickback of the Gas back-in. the burner housing by heating or igniting the fuel To prevent this, the housing 13 is provided with a cooling device. This cooler consists of a hollow housing 15, which sits in the burner housing and with Tubes 16 is equipped for the cooling liquid supply. The fuel supply pipe 17 runs through this housing and leads the fuel into a chamber 18, which is arranged between the housing in front of the outer surface of the plug 14. Through regulation The heating flame of the burner 14 has the same effect as in a 141uffel oven achieved.
Die rotierenden Herde q. sind auf Ringe 22 montiert, welche auf verjüngten Teilen 23 der Welle 2 sitzen (Abb. i). Zwischen den Herden q. wird die Welle 2 durch Ringe 24 aus feuerbeständigem Material umschlossen.The rotating herd q. are mounted on rings 22 which are tapered on Parts 23 of the shaft 2 sit (Fig. I). Between the herds q. wave 2 is through Enclosed rings 24 made of fire-resistant material.
Die festen Herde 5 ruhen auf Unterlagen 25, welche von der Außenwandung des Ofens in die Ofenkammer vorspringen. Sowohl die festen als auch die rotierenden Herde sind zweiteilig hergestellt (Abb. 3), damit sie schnell und leicht in den Ofen eingebracht und daraus entfernt werden können. Der Teil ia der äußeren Ofenwand ist nach Abb. 3 vom Wandteil i zu diesem Zweck abnehmbar vorgesehen.The fixed flocks 5 rest on pads 25, which are from the outer wall of the furnace protrude into the furnace chamber. Both the fixed and the rotating Cookers are made in two parts (Fig. 3) so that they can be moved quickly and easily into the Furnace can be introduced and removed from it. The part ia of the outer furnace wall is provided as shown in Fig. 3 removable from the wall part i for this purpose.
Auf gleiche Weise sind die Ringe 22 zweiteilig ausgeführt (punktierte Linien Abb. i). Auch die feuerbeständigen Blöcke 24 können ähnlich ausgeführt sein.In the same way, the rings 22 are made in two parts (dotted Lines Fig. I). The fire-resistant blocks 24 can also be designed in a similar manner.
