PATENTAMT.PATENT OFFICE.
Bei dem Calciniren von Bicarbonat mittelst directen Feuers erleidet die Güte des Fabrikats durch Aufnahme von Flugstaub und Zersetzungsproducten des verwendeten Koks Eintrag. Um diesen Uebelstand zu beseitigen und gleichzeitig jedes beliebige Brennmaterial zu obigem Zweck verwerthen zu können, verwendet der Erfinder einen Ofen, der so eingerichtet ist, dafs die Flamme mehrere über einander liegende Calcinirkammern umspült, welche zwar unter sich communiciren, aber als Ganzes geschlossen sind, und in denen mechanische Rührer das Calcmiren des Bicarbonate durch Umwenden desselben beschleunigen.When bicarbonate is calcined by direct fire, the quality of the manufacture suffers entry through the absorption of fly ash and decomposition products of the coke used. Around to eliminate this evil and at the same time any fuel for the above purpose To be able to utilize the inventor uses a furnace which is arranged in such a way that the Flame washes around several calcining chambers lying on top of one another, which are under each other communicate, but are closed as a whole, and in which mechanical stirrers do the calcifying accelerate the bicarbonate by turning it over.
Fig. ι der beiliegenden Zeichnung ist ein Verticalschnitt nach E-F, Fig. 3; Fig. 2 ein Verticalschnitt nach G-H, Fig. 3; Fig. 3 ein Horizontalschnitt nach C-D, Fig. 1; Fig. 4 ein Horizontalschnitt nach A-B, Fig. 1.Fig. Ι the accompanying drawing is a vertical section according to EF, Fig. 3; FIG. 2 shows a vertical section according to GH, FIG. 3; 3 shows a horizontal section according to CD, FIG. 1; FIG. 4 is a horizontal section according to AB, FIG. 1.
Die auf dem Rost R erzeugten Feuergase nehmen ihren Weg durch den Feuerraum F1, heizen dadurch den gemauerten Boden P des Calcinirraumes A^, gelangen durch die aufsteigenden Kanäle .ST1 K1 in den Feuerraum F^, der durch gufseiserne Platten von den Calcinirräumen abgeschlossen ist, von denen die untere Platte an den Calcinirraum A*, die obere an As durch Strahlung die Wärme der Feuergase abgiebt. In gleicher Weise werden die Feuergase durch den Feuerraum Fz und F1 geleitet und zur Wirkung gebracht und entweichen aus den Kanälen K% nach dem Schornstein.The fire gases generated on the grate R take their way through the combustion chamber F 1 , thereby heating the brick floor P of the calcining room A ^, pass through the ascending channels .ST 1 K 1 into the combustion chamber F ^, which is separated from the calcining rooms by cast iron plates is completed, of which the lower plate gives off the heat of the flue gases to the calcining room A *, the upper plate to A s by radiation. In the same way, the fire gases are passed through the combustion chamber F z and F 1 and brought into effect and escape from the channels K % after the chimney.
In entgegengesetzter Richtung wandert das Bicarbonat. Es gelangt durch den Fülltrichter B in den obersten Calcinirraum A. Hier wird dasselbe durch die an der stehenden, bei L gelagerten Welle W befindlichen Arme E mittelst der Rührer .S gewendet und vermöge der Stellung dieser Rührer gleichzeitig von der Peripherie des Raumes A nach der Mitte hin geschoben,-so dafs dasselbe durch die Fallbüchse O1 in den Calcinirraum A2 hinabfällt.The bicarbonate migrates in the opposite direction. It passes through the filling funnel B into the uppermost calcining room A. Here it is turned by means of the stirrer S by the arms E located on the standing shaft W mounted at L and, thanks to the position of this stirrer, simultaneously from the periphery of the room A to the Pushed towards the middle, so that it falls through the drop sleeve O 1 into the calcining chamber A 2 .
In diesem Räume stehen die Rührer S in entgegengesetztem Sinne und schieben das Material von der Mitte nach der Fallbüchse O2 u. s. f., bis es vollständig calcinirt bei <94 den Apparat verläfst.In this space the stirrer S are in opposite directions and push the material from the center to the case sleeve O 2, etc., until it is fully calcinirt verläfst the apparatus at <9. 4
An der Welle W ist das Zahnrad Z befestigt, mit Hülfe dessen dieselbe durch das Schneckenrad D angetrieben und gedreht wird.On the shaft W , the gear Z is attached, with the help of which the same is driven by the worm wheel D and rotated.
Die beim Calciniren erzeugten Gase, welche besonders für den Ammoniaksodaprocefs werthvoll sind, kann man durch den Stutzen C zur weiteren Verwendung und ohne Verdünnung abziehen.The gases produced during calcination, which are especially valuable for the ammonia soda process, can be drawn off through the pipe C for further use and without dilution.
Dieser Ofen kann auch zum Calciniren von anderen Materialien dienen.This furnace can also be used for calcining other materials.
