Description
Gutaufgabevorrichtung für Öfen zum Brennen von Zement und ähnlichen Stoffen Die Erfindung bezieht sich auf eine Gutaufgabevorrichtung, die für Öfen (Dreh- oder Schachtöfen) zum Brennen von Zement und ähnlichen Stoffen benutzt wird. Bei Zementbrennöfen ist eine der wichtigsten Voraussetzungen für die Erreichung einer hohen Ofenleistung eine gleichmäßige Gutaufgabe, deren Schwankungen erfahrungsgemäß stets eine Steigerung des Brennstoffbedarfs zur Folge haben. Eine dieser Steigerung entsprechende Erhöhung der Ofenleistung tritt nicht ein. Man muß deshalb die als am günstigsten festgestellte Gutaufgabemenge je Zeiteinheit einstellen und beibehalten.Material feed device for ovens for burning cement and the like Substances The invention relates to a material feed device for ovens (Rotary or shaft kilns) is used for burning cement and similar materials. When it comes to cement kilns, one of the most important prerequisites for achieving it is a high furnace output a uniform feed, the fluctuations of which experience has shown always result in an increase in fuel consumption. One of those increases a corresponding increase in furnace output does not occur. One must therefore use the as Set and maintain the most favorable amount of material to be added per unit of time.
Die bisher als Gutaufgabevorrichtungen bekannten Förderschnecken und Förderbänder haben durchweg entweder den an sie zu stellenden Anforderungen hinsichtlich einer gleichmäßigen Gutaufgabe und sicheren Betriebsweise nicht genügend entsprochen,- oder sie bedurften auf Grund ihrer verwickelten und leicht zu Störungen neigenden Bauart einer ständigen mühevollen Wartung.The screw conveyors and previously known as material feed devices Conveyor belts always have either the requirements to be placed on them an even feed and safe mode of operation not adequately met, or they needed because of their intricate and easily disruptive tendencies Constant laborious maintenance design.
Es sind auch bereits endlose Kastenförderer für die Gutaufgabe verwendet worden, und zwar dienen diese zugleich als Austragvorrichtung für einen Behälter oder Bunker, dem sie fortlaufend das Gut ihrem Fassungsvermögen entsprechend entnehmen. Die eine Unterkante des Behälters oder Bunkers wirkt dabei als Abstreichkante. Derartige Vorrichtungen sind jedoch für die Aufgabe von Zementrohmelil und ähnlichen Stoffen ungeeignet, da diese Stoffe nahezu wie Wasser fließen und infolgedessen durch einen Kastenförderer nicht in regelbarer Menge entnommen werden können.Endless box conveyors have also been used to feed the goods been, and they also serve as a discharge device for a container or bunker, from which they continuously remove the goods according to their capacity. One lower edge of the container or bunker acts as a scraper edge. Such However, devices are for the task of raw cement and similar materials unsuitable because these substances flow almost like water and consequently through one The box conveyor cannot be removed in an adjustable amount.
Erfindungsgemäß arbeitet eine Schnecke mit einem endlosen Kastenförderer derart zusammen, daß die Schnecke stets Gut im überschuß in den Kastenförderer aufgibt, diesen somit vollständig füllt, und daß ferner Abstreicher vorgesehen sind, die das jeweils überschüssige Gut z«,ecl,:s Rückführung in den Aufgabebehälter abstreichen. Bei der Vorrichtung gemäß der Erfindung werden also zwei an sich bekannte Mittel zur Erreichung eines neuen technischen Fortschritts zusammen benutzt.According to the invention, a screw works with an endless box conveyor together in such a way that the screw always feeds excess material into the box conveyor, this thus completely fills, and that also scrapers are provided that Scrape off the excess material z «, ecl,: s return to the feed container. In the device according to the invention, there are two means known per se used together to achieve a new technical advance.
Auf der Zeichnung ist als Ausführungsbeispiel des Erfindungsgegenstandes die Seitenansicht einer Gutaufgabevorrichtung in Verbindung mit einem Drehofen zum Brennen von Zement veranschaulicht.In the drawing is an exemplary embodiment of the subject matter of the invention the side view of a material feed device in connection with a rotary kiln for How to burn cement.
Aus einem Behälter i, der durch ein Becherwerk 2 gespeist wird, wird das Gut mittels einer Schnecke 3 entnommen und auf einen endlosen Kastenförderer 4 geworfen. Dieser ragt mit einem Abwurfende in den geschlossenen Kopf einer Schurre 5 hinein, über die das Gut in den Ofen 6 gelangt. Die Schnecke 3 trägt fortlaufend so viel Gut aus, daß die Kästen des Förderers 4 stets ganz gefüllt werden. Zur Erreichung einer gleichmäßigen Füllung der Kästen dienen Abstreicher 7, die zweckmäliig schräg zur Förderebene stehen und überschüssiges Gut seitwärts abdrängen. Dieses fällt dann über eine Schurre S in das Becherwerk 2 zurück und gelangt wieder in den Behälter. Die Umlaufgeschwindigkeit sowohl der Schnecke 3 als auch des Kastenförderers 4. sind einstellbar, und zwar genügt bei der Schnecke eine grobe Einstellung, während die feine Einstellung zur Erreichung der gleichmäßigen Gutaufgabe durch den Kastenförderer bewirkt wird.From a container i, which is fed by a bucket elevator 2, is the material is removed by means of a screw 3 and placed on an endless box conveyor 4 thrown. The end of this protrudes into the closed head of a chute 5, through which the material enters the furnace 6. The screw 3 carries continuously so much good that the boxes of the conveyor 4 are always completely filled. To achieve A uniform filling of the boxes are used by scrapers 7, which are expediently inclined stand to the conveying level and push away excess material to the side. This one falls then back into the bucket elevator 2 via a chute S and returns to the container. The speed of rotation of both the screw 3 and the box conveyor 4. are adjustable, and a rough setting is sufficient for the worm while the fine setting to achieve the uniform feed of the material by the box conveyor is effected.
