Description
Rührarmbefestigung für mechanische Röstöfen zur Abröstung von Pyrit und anderen Schwefelmaterialien. Es sind eine ganze Reihe Rührarmbefastigungen bei .mechanischen Röstöfen bekannt; diese haben aber mehr oder weniger den Nachteil, daß beim Bruch eines Rührarmes das im Rührwerk sitzende Stück nur unter großen Schwierigkeiten herauszubringen ist. Perner müssen bei einzelnen Konstruktionen erst eine Anzahl Schrauben gelöst werden, welche sogar meistens innerhalb des Ofens angebracht waren, oder es mußte die Kühlmittelzuführung zur Kühlung der Rührarme besonders abgeschraubt werden oder schließlich der Rührarm vom Riihrarmende aus, also von der Ofenperipherie aus, mittels langer durch den Rührarm hindurch gesteckter Schlüssel Iefestigt 1-zw. gelöst werden, was natürlich nur unter großen Schwierigkeiten möglich ist.Mixing arm attachment for mechanical roasting ovens for roasting pyrite and other sulfur materials. There are a number of agitator arm attachments included . known mechanical roasting ovens; but these have more or less the disadvantage that when a paddle breaks the piece sitting in the agitator only with great difficulty is to be brought out. Perner must first have a number for individual constructions Screws are loosened, which were even mostly attached inside the furnace, or it had to be the coolant supply especially for cooling the agitator arms be unscrewed or finally the agitator arm from the end of the agitator arm, i.e. from the furnace periphery using a long key inserted through the agitator arm 1-betw. can be solved, which of course is only possible with great difficulty is.
Weiter sind Rührarmbefestigungen an Tragringen konstruiert, 1-ei denen der Rührarm einfach .durch eine Öffnung .des Tragringes hindurchgesteckt und an den Tragring mittels lösbaren Verschlusses befestigt wird. Bei jedem Ofen jedoch geht in der Mitte ein Teil der Sohle als Röstfläche verloren, weil dort die Erz- und Gasü,:,ergänge angelracht sind. Deshalb mußten hei den bisherigen Ring- und andere Öfen der Rührarm um die Breite dieser Übergänge länger sein, also der im Ofeninnern befindliche Teil des Rührarmes wußte genau so lang sein wie die eigentliche Röstfläche -[- Fläche für die Erz- und Gasübergänge, wodurch die Rührarme ungewöhnlich lang wurden und leicht zu Bruch gingen.Furthermore, agitator arm attachments are constructed on support rings, 1-ei those the agitator arm simply pushed through an opening in the support ring and attached the support ring is attached by means of a detachable lock. With every stove, however if part of the sole is lost in the middle as a roasting surface, because there the ore and Gasü,:, gangways are attached. Therefore had to be called the previous ring and other ovens the agitator arm must be longer by the width of these transitions, i.e. the one in the The part of the paddle inside the furnace knew to be exactly as long as the actual one Roasting area - [- Area for the ore and gas transitions, making the agitators unusual became long and easily broken.
Im Gegensatz hierzu sind bei vorliegender Erfindung an jedemRü:hrarrntragring mehrere Aufnahmegehäuse ('#"orbau) für die Rührarme h.efesti.gt oder angegossen, welche bis über die Erz- und Gasdurchgänge in den Ofen, zur Peripherie hin, und gleichzeitig in der entgegengesetzten Richtung in den durch den Rührarmtragring gebildeten Schacht hineinragen. Dadurch ist es möglich, den im Ofeninnern Befindlichen Teil des Rührarmes ganz kurz zu halten und so die Betriebssicherheit Ledeutend zu erhöhen.In contrast, in the present invention there are on each agitator support ring several housing ('# "structure) for the agitator arms, firmly fixed or cast, which up to the ore and gas passages in the furnace, to the periphery, and at the same time in the opposite direction in the through the agitator support ring formed shaft protrude. This makes it possible for those inside the furnace Keeping part of the agitator arm very short and thus significantly increasing operational safety raise.
Der Rührarm selbst wird nicht in bekannter Weise unmittelbar in eine Öffnung des ringförmigen Trägers gesteckt und einfach durch einen lösbaren Verschluß in seiner Lage gehalten, sondern in einen .den Tragring durchsetzenden Vorbau gesteckt und durch einen Schraubenbolzen in diesem hineingepreßt. Gleichzeitig ist es aber möglich, den Rührarm mittels dieses Schraul enbolzens aus dem Vorbau (Aufnahmegehäuse) herauszudrücken.The paddle itself is not directly in a known manner Opening of the ring-shaped carrier inserted and simply by a releasable lock held in its position, but inserted into a .the support ring penetrating stem and pressed into it by a screw bolt. But at the same time it is possible to remove the agitator arm using this screw bolt from the stem (housing) to push out.
Der ringförmige Träger nimmt die Rührarme mit durch den Ofenraum, und da der Vorbau e7_enfalls mitrotiert sowie nur bis zur eigentlichen Röstfläche reicht, wird weder an dieser noch an den Erz- und Gasdurchgängen Querschnitt weggenommen.The ring-shaped carrier takes the agitator arms with it through the furnace chamber, and since the stem may rotate with it and only up to the actual roasting area is sufficient, cross-section is not removed either from this or from the ore and gas passages.
Die Erfindung ist in beiliegender Zeichnung beispielsweise dargestellt, und zwar zeigt: Abb. r den Grundriß eines Rührarmes mit dem entsprechenden Teil des ringförmigen Trägers und Aufnahmegehäuses (Vorbau), A?sl>. a einen Längsschnitt durch das Aufnahmegehäuse mit eingestecktem Rührarm und einen Teil der Röstsohle mit den Erz-und Gasdurchgängen, A':-b. 3 einen Querschnitt durch .das Aufnahmegehäuse.The invention is shown in the accompanying drawing, for example, namely shows: Fig. r the plan of a stirring arm with the corresponding part of the ring-shaped support and housing (stem), A? sl>. a a longitudinal section through the housing with inserted agitator arm and part of the roasting sole with the ore and gas passages 'A': - b. 3 shows a cross section through the receiving housing.
Der Rührarm a wird einfach in das Aufnahmegehäuse (Vorbau) b, welches an dem Rührarmtragring c befestigt oder angegossen ist, eingescholten und in gewöhnlicher Weise mittels eines Schraugenholzens d in den Vor,-au b hinein- epreßt, so daß der Rührarm fests_tzt, wobei aber alle zu lösenden Teile außerhalb des Ofens liegen.The agitator arm a is simply inserted into the housing (stem) b, which is attached to the agitator support ring c or cast, insulated and in the ordinary Way by means of a sloping wood d into the front, -au b, so that the The agitator arm is fixed, but all parts to be loosened are outside the furnace.
Der Rührarmtragring c ist an dem Gerüst e g efestigt und wird von diesem mit herumgenommen.The agitator support ring c is fixed to the frame e and is of taken around with this.
Das Aufnahmegehäuse b ist sehr weit in das Ofeninnere zur Peripherie hin hineingebaut, wodurch !der nm Ofeninnern befindliche Teil des Rührarmes a nur ganz kurz behalten zu werden Braucht. Da die Erz- und Gasübergänge sowieso einen Teil der Ofensohle `veä nehmen, wird durch diese Konstruktion erre:cht, daß die eigentliche Röstfläche nicht verkleinert wird und der Vorbau b die Erz-und Gasdurchgänge nicht gehindert.The receiving housing b is very far into the furnace interior to the periphery built into it, which means that the part of the agitator arm located inside the furnace is only Needs to be kept very briefly. Since the ore and gas junctions are one anyway Part of the furnace sole `veä take, is achieved by this construction that the actual roasting area is not reduced and the porch b the ore and gas passages not prevented.
Der Durchmesser des Rührarmtragringes c ist so groß gewählt, daß man bequem hineinsteigen kann, und sind zu diesem Zweck gewöhnliche Steigleitern vorgesehen, welche dazu dienen, den Schraubenbolzen d zu lösen bzw. anzuziehen und .den Rührarm aus dem Vorbau herauszudrücken.The diameter of the Rührarmtragringes c is chosen so that you can can easily climb into it, and normal fixed ladders are provided for this purpose, which serve to loosen or tighten the screw bolt d and .the agitator arm to push out of the stem.
