LeientZuschlag zur Herstellung von Leichtbeton aus thermisch vorbehandelten Abfallprodukten der Zechen - und HüttenindustrieLeient surcharge for the production of lightweight concrete from thermal pretreated waste products from the coal and steel industry
Die vorliegende Erfindung betrifft einen leichten Zuschlag zur Herstellung von Leichtbeton und ein Verfahren zur Herstellung dieses Zuschlages aus Abfall- und Nebenprodukten der Hütten und Zechen.The present invention relates to a lightweight aggregate for the production of lightweight concrete and a method for production this surcharge from waste and by-products from smelters and mines.
Einleitungintroduction
Im Steinkohlenbergbau, der Hütten- und Zechenindustrie, sowie in der Aluminiumindustrie fallen in großem Umfange Rohstoffe an, die als Abfallprodukte dem Aufbau und der Zusammensetzung nach einer Veredlung nur in geringem Umfange zugeführt werden können. Große Haldenbildungen liegen daher in dieser Industrie überall vor.In hard coal mining, the iron and steel industry, as well as There are large quantities of raw materials in the aluminum industry in terms of their structure and composition as waste products after a refinement only supplied to a small extent can be. There are therefore large heaps of heaps in this industry everywhere.
Die Bemühungen die Abfallprodukte, wie Bergesch!amme, Plugaschen, Waschberge, Rotschlamm uam., als Rohstoff zur Fertigung von Erzeugnissen der Steine und Erden Industrie zu verwenden, sind bekannt. Die aus diesen Rohstoffen erstellten Erzeugnisse kommen aber den Produkten,- welchen diese ebenbürtig sein sollen, wie BlähtOn und Blähschiefer oder leichten Zuschlägen hoher Güte, nicht gleich. Die Erzeugnisse aus diesen Rohstoffen sind nicht, marktgängig und wirtschaftlich nicht vertretbar.Efforts to remove waste products, such as Bergesch! Amme, Plugaschen, Wash mountains, red mud, etc., as raw materials for production of products of the stone and earth industry too use are known. The ones made from these raw materials But products come from products - which these should be equal, such as expanded clay and expanded slate or light surcharges of high quality, not the same. The products from these raw materials are not, marketable and economical not justifiable.
Die aus diesen Abfallprodukten hergestellten Erzeugnisse, leichter Zuschlag, sind daher qualitativ nur bedingt vertretbar.. The products made from these waste products, slight surcharge, are therefore only partially justifiable in terms of quality.
Leichtzuschlag und HerstellungLightweight aggregate and manufacture
Erfindungsgemäß wird hier nun ein Verfahren aufgezeigt, nach welchem die hier genannten Abfallprodukte, wie Bergeschlämme, Waschberge und Flugaschen in Verbindung mit Rptsehlamm oder ähnlichen Abfällen, im Wege einer thermischen Vorbehandlung, so umgewandelt werden, daß ein Rohstoff anfällt, aus welchem leichter poriger,, geblähter Zuschlag,, gefertigt werden kann.According to the invention, a method is now shown here, according to which the waste products mentioned here, such as mining sludge, Wash mountains and fly ash in connection with Rptsehlamm or similar waste, by means of thermal pretreatment, be converted in such a way that a raw material is obtained which light, porous, "expanded aggregate" are manufactured can.
Dieses geschieht in der Weise, daß die Bergeschlämme d-.es Steinkohlenbergbaues/ und: oder andere gleichwertige Produkte, in einer oxydierenden Atmosphäre in TemperaturbereichenThis happens in such a way that the mountain sludge d.es Coal mining / and: or other equivalent products, in an oxidizing atmosphere in temperature ranges

bis zu 86O°C erhitzt wird und eine ausreichende Verweilzeit in dieser Atmosphäre erhält.is heated up to 86O ° C and a sufficient residence time in this atmosphere.
Im Zuge dieser thermischen Vorbehandlung werden alle Kohleteile, die im Abfallprodukt enthalten sind ausgebrannt. Andere Bestandteile des Rohstoffes, Bergesehlamme, werden durch Entfernung des Kohlenstoffes, indirekt angereichert. In the course of this thermal pretreatment, all coal parts, which are contained in the waste product burned out. Other components of the raw material, mountain flames, are enriched indirectly by removing the carbon.
Der Rohstoff, welcher als Folge der thermischen Vorbehandlung mit festgelegter Dauer der Einwirkung der oxydierenden Atmosphäre und Hitze anfällt, ist im weiteren verfahrenstechnischen Ablauf der Fertigung, wie ein aufbereiteter Rohton zu behandeln, bei welchem das Blähvermögen anzureichern ist. Diese Anreicherung der einzelnen Komponenten des Aufbaues des angefallenen Rohstoffes, erfolgt über Zusätze, die auch bei mangelhaft blähbären Tonen der natürlichen Vorkommen, angewendet werden.. Hierzu gehören die Abfall- und Nebenprodukte der Hütten und auch vorwiegend die Abfälle aus der Aluminium-Industrie..The raw material, which as a result of the thermal pretreatment with a fixed duration of the action of the oxidizing atmosphere and heat, is in the further process-technical Process of production, how to treat a processed raw clay, in which the expandability is enriched is. This enrichment of the individual components of the structure of the accumulated raw material takes place about additives that can also be used in the case of poorly puffy clays natural occurrences. These include the waste and by-products of the smelters and also predominantly the waste from the aluminum industry ..
Im weiteren verfahrenstechnischen. Ablauf der Herstellung von leichtem Zuschlag, wie Blähton und/oder Blähschiefer artige Produkte, wird im Trocknungsprozeß der umgewandelte Rohstoff mit Zusätzen angereichert, homogenisiert und zu Granulat, wie üblich im Granulierteller oder gleichwertigen Aggregaten, verarbeitet.In the further procedural. Production process of light aggregate, such as expanded clay and / or expanded slate like products, the converted raw material is enriched with additives in the drying process, homogenized and processed into granules, as usual in the granulating plate or equivalent aggregates.
Das mit Wasser,oder mit Wasser und allgemein bekannten Zusätzen angereicherte Wassermischungen, hergestellte Granulat, wird im Drehofen oder im Wirbelsehlchtofen der Hitzeeinwirkung ausgesetzt. Die Temperaturbereiche der Hitzeeinwirkung liegen, wie bei üblichen und gebräuchlichen Tonen, etwa zwischen ll60 bis 1^00 C. Die Dauer der Hitzeeinwirkung in diesen Temperaturberichen, richtet sich nach den angewendeten verfahrenstechnischen Auslegung der angewendeten Aggregate.That with water, or with water and generally known additives fortified water mixtures, manufactured granules, is exposed to heat in the rotary kiln or in the vertebral loft oven exposed. The temperature ranges of the heat are, as with common and customary clays, about between ll60 to 1 ^ 00 C. The duration of the exposure to heat in these temperature ranges, depends on the applied procedural design of the applied Aggregates.
In der hier genannten Verfahrensweise hergestellte und der Hitzeeinwirkung ausgesetzte Granulate, entsprechen dem Granulat Blähton. Sie sind Erzeugnisse mit definierter Form und im Voraus festlegbaren Eigenschaften., Das Endprodukt ist somit ein Erzeugnis, welches dem Blähton gleichwertig ist.Manufactured in the procedure mentioned here and the Granules exposed to heat correspond to the granules Expanded clay. They are products with a defined shape and properties that can be determined in advance., The end product is thus a product which the expanded clay is equivalent.
Durch die hier angegebenen Maßnahmen, die der Erfindung zu gründe leigen, werden Abfallprodukte der Industrien in großem Umfange einer Veredlung zugeführt und zu Erzeugnissen umgewandelt, die technisch und wirtschaftlich vertretbar sind. Bei einer Haldenbildung würden diese Abfallprodukte der Umweltverschmutzung im wesentlichen Vorschub leisten.By the measures specified here, the invention too reasons are becoming waste products of industries in large quantities Scope of refinement and converted into products that are technically and economically justifiable are. If they were dumped, these would be waste products contribute substantially to environmental pollution.
