Description
Vorrichtung zur Abdichtung umlaufender Trommeltrockner, Drehöfen u. dgl. in der Ofenwand. Gegenstand der Erfindung ist eine Abdichtung sich drehender Trockentrommeln, Rohrmühlen o. dgl. gegen feststehende oder auch bewegliche Teile der Gesamtanlage.Device for sealing rotating drum dryers, rotary kilns, etc. Like. In the furnace wall. The invention relates to a seal for rotating Drying drums, tube mills or the like against fixed or moving parts of the entire system.
Die bisher bekannten Abdichtungen dichteten bei stärkerem Schlagen der Trommel; welches infolge Verschleißes der Lagerungen, Verziehens des Rohres, durch unglrichmäßige Erhitzung usw. eintrat, nicht vollständig ab. Während des Betriebes wurden daher besonders bei großen Anlagen bedeutende Frisehluftmengen mit angesaugt. Diese Frischluft hat nun eine Erniedrigung der Temperatur der Trockenluft und somit eine Verschlechterung des Gesamtwirkungsgrades der Trockenanlage zur Folge. Sehr wichtig ist die völlige Abdichtung bei Anlagen in chemischen Fabriken, soweit sie mit wenn auch nur geringem, überdruck arbeiten. Durch Austreten von mitunter giftigen Gasen, werden zumindest die bedienenden Arbeiter belästigt, wenn nicht überhaupt der Betrieb in Frage gestellt ist.The seals known up to now sealed with stronger impact the drum; which as a result of wear of the bearings, distortion of the pipe, occurred due to improper heating, etc., not completely removed. During operation Therefore, especially in large systems, significant amounts of hairdressing air were sucked in. This fresh air now has a lowering of the temperature of the dry air and thus result in a deterioration in the overall efficiency of the drying system. very It is important to ensure complete sealing in the case of equipment in chemical factories, as far as they are work with overpressure, even if only slightly. Through leakage of sometimes poisonous Gases, at least the operating workers are harassed, if not at all the operation is in question.
Die Abdichtung gemäß der Erfindung beseitigt diese Nachteile durch die Anwendung von in eineM Rohrring abdy4tenden Kugelringen und.hat noch .den Vorzug größerer Billigkeit im VergleieFi`'zti''@nderen unvollkommeneren Einrichtungen.The seal according to the invention eliminated these Disadvantages due to the use of ball rings dia4ting into a tubular ring and. Has nor the advantage of greater cheapness in comparison to other imperfect ones Facilities.
Nachstehend ist ein Ausführungsbeispiel. Abb. i, 3 und q. zeigen die Abdichtungsvorrichtung im Längsschnitt. Abb. z ist ein Querschnitt.The following is an embodiment. Fig. I, 3 and q. show the Sealing device in longitudinal section. Fig.z is a cross section.
An dem abzudichtenden Teil der Gesamtanlage H der Kalorifere einer Trockentrommelanlage wird der Ring C dichtschließend befestigt.On the part of the overall system H to be sealed off the calorifere one The ring C is tightly attached to the drying drum system.
Mit Rücksicht darauf, daß bei warmgehenden Trockenanlagen das Rohr F wandert (wie durch Doppelpfeil J angedeutet), wird der Ring D in einer bestimmten Entfernung vom Ring C angebracht.With regard to the fact that with warm-running drying systems the pipe F wanders (as indicated by double arrow J), the ring D becomes in a certain Removed from ring C.
Derselbe kann sogar, um die Reibung zwischen D und E auszuschalten, auf Kugeln laufend ausgebildet werden.The same can even be used to eliminate the friction between D and E, be trained on balls running.
Um die beiden Kugelringe C und D legt sich nun ein aus horizontal und parallel liegenden Lamellen El, E2, Es usw. bestehender Zylinderring E. Die einzelnen Lamellen werden durch eine in einer Nut liegende Ringfeder G zusammengehalten. Hierdurch ist ein elastischer Ring geschaffen, durch welchen alle senkrecht auftretenden Stöße aufgenommen werden, so daß immer ein gleichbleibender Durchmesser auch bei stärkerem Verschleiß gewährleistet ist.Around the two spherical rings C and D there is now a horizontal and parallel lamellas El, E2, Es etc. existing cylinder ring E. The individual slats are held together by an annular spring G located in a groove. This creates an elastic ring through which all of the vertically occurring Shocks are absorbed, so that there is always a constant diameter even with greater wear is guaranteed.
Die normale Lage des Zylinderringes wird durch die drei Ausgleichvorrichtungen 1<, 1(l, K2 geregelt. Diese sind so ausgebildet, daß sie eine Bewegung des Ringes nach allen Seiten gestatten, aber das Bestreben haben, den Ring in der normalen Lage festzuhalten.The normal position of the cylinder ring is determined by the three compensating devices 1 <, 1 (l, K2 regulated. These are designed in such a way that they cause a movement of the ring in all directions, but strive to keep the ring in the normal Location.
Die Wirkungsweise der Abdichtung ist in Abb. 3 und q. schematisch veranschaulicht. Abb.3 zeigt die normale Lage der Abdichtungsringe.The way in which the seal works is shown in Fig. 3 and q. schematic illustrated. Fig.3 shows the normal position of the sealing rings.
Abb. q. zeigt eine Stellung, in welcher die Mittelachse des Rohres F und somit auch des Ringes D von L nach M verschoben ist. Da nun die Ringe D und C kugelförmige Oberflächen haben, bleiben deren Durchmesser bei allen im praktischen Betriebe möglichen Stellungen gleich, so daß der Zylinderring E immer vollkommen abdichtet.Fig.q. shows a position in which the central axis of the tube F and thus also of the ring D is shifted from L to M. Since the rings D and C now have spherical surfaces, their diameters remain the same in all possible positions in practical operation, so that the cylinder ring E always seals completely.
