Description

Verfahren zur staubfreien Entleerung von mit Unterwind betriebenen Schachtöfen zum Brennen von Zement, Kalk, Dolomit u. dgl. = Die bisher bekanntgewordeneil Vorrichtungen zur staubfreien Entleerung von mit Unterwind betriebenen Schachtöfen erfüllen ihren Zweck im allgemeinen nur unvollkommen, da die mechanischen Vorrichtungen, wie Schieber-, Klappen-, Ventil-, Fächerwalzenverschlüsse usw., infolge des starken Verschleißes, der bei dem oft grobstückigen und harten Austragegut unvermeidlich ist, eine gute Abdichtung nicht erzielen lassen.Process for the dust-free emptying of operated with underwind Shaft furnaces for burning cement, lime, dolomite and the like = those that have become known so far Devices for the dust-free emptying of shaft furnaces operated with underwind generally serve their purpose only imperfectly, since the mechanical devices, such as slide, flap, valve, fan roller locks, etc., due to the strong Wear, which is inevitable with the often lumpy and hard discharge material a good seal cannot be achieved.

Das neue Verfahren ermöglicht eine tatsächlich staubfreie Austragung, die durch den Verschleiß nicht beeinträchtigt wird. Die Neuerung besteht darin, daß die Austrittsöffnung des Schachtofens durch einen sich drehenden Teller derart verschlossen wird, daß über demselben ständig eine Gutsäule bekannter Art besteht. Durch die Gutsäule wird der Austritt von. Preßluft auf ein geringes Maß beschränkt. Der Teller ist in einem verschlossenen Gehäuse angeordnet, an welches eine Saugrohrleitung zum Absaugen der geringen Menge Staubluft angeschlossen ist.The new process enables an actually dust-free discharge, which is not affected by wear and tear. The innovation is that the outlet opening of the shaft furnace through a rotating plate in such a way is closed that there is always a known type of estate column above the same. The exit of. Compressed air limited to a low level. The plate is arranged in a closed housing to which a suction pipe is attached is connected to extract the small amount of dusty air.

Ein Ausführungsbeispiel zeigt die' Figur. Es bedeuten hierin a den unteren Teil eines mit Unterwind geblasenen Schachtofens, b ein Staurohr zur Erzielung einer hohen Gutschicht, c einen umlaufenden Teller, welcher auf bekannte Art angetrieben und mittels Abstreicher entleert wird, d die Auslaßöffnung des den Teller umgebenden Gehäuses, c die Gutsäule, f eine Saugrohrleitung bekannter Art, g einen Staubsammelbehälter bekannter Art und 1a einen Ventilator bekannter Art. Die Entleerung des Tellers ist derart geregelt, daß über demselben stets eine gewisse Gutschicht steht, die nur eine ganz geringe Luftmenge aus dem Ofen herausdringen läßt. Diese Luftmenge wird zusammen mit der beim Abstreifen des staubhaltigen Gutes entstehenden Staubluft schon innerhalb des um den Teller angeordneten Staubgehäuses abgesaugt. Die Staubluft kann zur Erzeugung des Unterwindes auf bekannte Art verwendet werden, wozu man sie zweckmäßig vorher in einem Reiniger bekannter Art entstaubt.An embodiment shows the 'figure. It means here a den lower part of a shaft furnace blown with under wind, b a pitot tube to achieve a high layer of material, c a rotating plate, which is driven in a known manner and emptied by means of a scraper, d the outlet opening of the surrounding plate Housing, c the column of goods, f a suction pipe of a known type, g a dust collector known type and 1a a fan of known type. The emptying of the plate is regulated in such a way that there is always a certain good layer above it, the allows only a very small amount of air to escape from the oven. This amount of air becomes together with the dusty air produced when the dusty material is wiped off already sucked off inside the dust housing arranged around the plate. The dusty air can be used to generate the downwind in a known way, for which purpose it is expediently dedusted beforehand in a known type of cleaner.
