Description

Ofen zum Brennen, Rösten, Agglomerleren usw. von Kalk, Gips, Zement, Erzen u. dgl. Den Gegenstand detr Erfindung bildet ein Ofen, der zum Brennern von Kalk, Gips, Zement u. dgl. oder zum Rösten von Erzen u. dgl." zum Agglomerieren und ähnlichen Verfahren dienen kann.Furnace for burning, roasting, agglomerating etc. of lime, gypsum, cement, Ores and the like. The subject of the invention is a furnace which is used for burning Lime, gypsum, cement and the like or for roasting ores and the like "for agglomeration and similar procedures.

Der Ofen besteht, wie die Zeichnung an drei Ausführungsbeispielen darstellt, aus einem Gehäusea, in das mehrfach untereinanderliegenda schräge Gleitflächen b eingebaut sind, die in wagerechte, oder vorwiegend wagerechte, hin und her gehende (oszillatorische) Schwingungen versetzt werden (Rollenlager c). Der zu behandelnde Stoff tritt oben bei d ein, gleitet auf den geneigten Unterlagen b herab und begegnet auf diesem Wege zu einem unteren Auslauf einem; Strome der Heizgase, die auf ihn einwirken sollen. Durch eine besondere obere Abströmungs,-öffnung x können diese Gase die Vorrichtung verlassen. Die Wände der Vorrichtung müssen geeignet sein, den hohen Temp.era;-turen zu widerstehen, beispielsweise also mit feuerfesten Auskleidungen versehen sein. Ferner muß eine entsprechende Feuerung oder Hitzequelle eingebaut sein; - beispiels#-weise kann eine zum Einblasen flüssigen oder staubförmigen Brennstoffes nach Art von Drehrohröfen geeignete Düse e (Abb. t) angeordnet werden. Zum Agglomerieren usw. empfiehlt sich der Ein- oder Anbau eines besonderen Feuerschachtes f mit gesonderter Einschüttvorrichtungg (Abb. z), falls der Brennstoff nicht zugleich mit dem Brenngut aufgegeben werden soll.. Die Feuerstelle wird zweckmäßigerweise so weit vom Ende der Brenngutbahn entfernt gelegt (beispielsweise in den vorletzten oder in einen noch, früheren Zug), daß unter der Feuerzone noch eine Abkühlungszone gebildet wird, die das Brenngut zu durchlaufen hat, bevor es denl Ofen verläßt. Luftzutrittsöffnungen können, ebenso wie Beschickungs- und Entleerungsvorrichtungen, in der auch sonst bei derartigen öfen bekannten Weise angeordnet werden.The furnace consists of three exemplary embodiments, as shown in the drawing represents, from a housing a, into which multiple sloping sliding surfaces lie one below the other b are built into the horizontal, or predominantly horizontal, reciprocating (oscillatory) vibrations are offset (roller bearing c). The one to be treated Fabric enters at the top at d, slides down on the inclined supports b and meets in this way to a lower outlet; Streams of the heating gases flowing on him should act. Through a special upper outflow opening x these can Gases leave the device. The walls of the device must be suitable to withstand the high temp.era; -turen, for example with refractory linings be provided. In addition, a suitable furnace or heat source must be installed be; - for example # -Wise, a liquid or dust-like fuel can be injected suitable nozzle e (Fig. t) can be arranged according to the type of rotary kiln. For agglomeration etc. it is advisable to build in or add a special fire shaft f with a separate one Feeding device (Fig. Z), if the fuel is not at the same time as the material to be fired to be abandoned .. The hearth is expedient so far from the end of the kiln length (for example in the penultimate or in an even, earlier move) that under the fire zone there is still a cooling zone is formed, which the kiln has to pass through before it leaves the furnace. Air inlet openings, as well as loading and emptying devices, can be arranged in the manner otherwise known in such ovens.

Der Ofen kann einen beliebigen, z. B. einen kreis- oder einen aus zwei gleichachsigen Zylindern (a, ,a1) gebildeten. ringförmigen Grundriß haben, in welchem Falle ihm zweckmäßigerweise eine kreisförmige Schwingbewegung um eine senkrechte oder vorwiegend senkrechte Achse gegeben wird und die Gleitflächen schraubenförmig verlaufen können (Abb. 3).The furnace can be any, e.g. B. a circular or one off two coaxial cylinders (a,, a1) formed. have a ring-shaped plan, in which case it expediently a circular oscillating movement around one vertical or predominantly vertical axis is given and the sliding surfaces are helical can run (Fig. 3).

öfen mit mehrfach übereinanderliegenden Gleitflächen und hin und her gehender Bewegung sind an sich bekannt. Dabei ist aber die Bewegung eine Schwingbewegung um eine wagerechte Achse.ovens with multiple sliding surfaces and back and forth walking movement are known per se. But the movement is a swinging movement around a horizontal axis.

PATENT-ANSPRU&GaE: i. Ofen zum Brennen, Rösten, Agglomerieren usw. von Kalk, Gips, Zem!ent<y Erzen u. dgl., bei dem das Ofengehäuse in hin und her gehende Bewegung versetze wird und mit mehrfach übereinanderliegenden Gleitflächen (b), die das Brenngut nacheinander durchläuft, versehen ist, dadurch gekennzeichnet, daß die hin und her gehende Bewegung wagerecht oder vorwiegend wagerecht und parallel zur Gutbewegung verläuft. a. Ofen nach Anspruch i, dadurch gekennzeichnet, daß das Gehäuse einen aus zwei Zylindern (a, a1) gebildeten Ringraum bildet, der um eine senkrechte Achse schwingt und in dem die Gleitflächen (b) schraubenförmig verlaufen. 3. Ofen nach Anspruch i, dadurch ge. kennzeichnet, daß die Brennzone nicht im letzten, sondern in einem vorhergehenden Zuge angeordnet wird, so daß hinter der Brennzone noch eine Kühlzone gebildet wird. PATENT CLAIMS: i. Furnace for burning, roasting, agglomerating etc. of lime, gypsum, cement, ores and the like, in which the furnace housing is set in reciprocating motion and with multiple sliding surfaces (b), which are placed one on top of the other, which the firing material one after the other runs through, is provided, characterized in that the reciprocating movement runs horizontally or predominantly horizontally and parallel to the movement of the material. a. Oven according to claim i, characterized in that the housing forms an annular space formed from two cylinders (a, a1) which oscillates about a vertical axis and in which the sliding surfaces (b) run helically. 3. Oven according to claim i, characterized ge. indicates that the burning zone is not arranged in the last, but in a preceding pass, so that a cooling zone is also formed behind the burning zone.
