Description

Die Erfindung bezieht sich auf eine mehrteilige Koksofentür mit einem Schutzschild, der aus zwei mit Abstand vom Türkörper gehaltenen Formprofilen besteht, die mit geringem Abstand voneinander angeordnet sind und einen senkrechten, an den Schmalseiten grösstenteils offenen Gaskanal bilden.The invention relates to a multi-part coke oven door with a protective shield, which consists of two molded profiles held at a distance from the door body, which are arranged at a short distance from one another and form a vertical, largely open gas channel on the narrow sides.

Angestrebt werden Koksofentüren mit möglichst hoher Dichtwirkung.Coke oven doors with the highest possible sealing effect are aimed for.

Derartige Koksofentüren sind beispielsweise aus der DE-A-3327337 (EP-A-0163773) bekannt, die sich insbesondere auf einer neuartigen Ausbildung des Türkörpers mit der dazugehörigen Dichtungseinrichtung bezieht. Mit dem vergleichsweise leichten Türkörper ist nach den Ausführungszeichnungen dieser Schrift wahlweise ein konventioneller feuerfester Türstopfen kombiniert.Such coke oven doors are known, for example, from DE-A-3327337 (EP-A-0163773), which relates in particular to a novel design of the door body with the associated sealing device. With the comparatively light door body, a conventional fireproof door plug is optionally combined according to the design drawings in this document.

Die bekannte leichte Koksofentür beinhaltet eine Aufteilung in ein Dichtorgan und eine Rahmenkonstruktion, wobei die Rahmenkonstruktion weitgehend frei von Wärmespannungen gehalten wird und das Dichtorgan an den Ofenrahmen anpresst. Wesentlich wird die Bauweise dabei noch durch den Türstopfen und die damit verbundene Belastung bestimmt.The known light coke oven door includes a division into a sealing member and a frame construction, the frame construction being kept largely free of thermal stresses and pressing the sealing member against the furnace frame. The design is essentially determined by the door plug and the associated load.

Aufgabe der Erfindung ist es nun, die Belastung des Türkörpers zu verringern und dadurch eine noch leichtere Bauweise zu ermöglichen, die bei gleichbleibender Dichtwirkung weitere wirtschaftliche Vorteile gewährt.The object of the invention is now to reduce the load on the door body and thereby enable an even lighter construction which, with the same sealing effect, affords further economic advantages.

Die Aufgabe der Erfindung wird durch das Kennzeichen des Hauptanspruches gelöst. Dabei greift die Erfindung auf die aus der DE-C-186934 bekannte Lösung zurück und hat dabei nur einen scheinbaren Nachteil, als der separate Schutzschild eine Bedienungsmechanik erfordert. Üblicherweise ist jede Maschine zum Koksdrücken jedoch nicht nur mit einer Türhebevorrichtung, sondern zusätzlich mit einer Türreinigungsvorrichtung versehen. Überraschenderweise sind die Verunreinigungen der Ofentürdichtflächen jedoch so gering, dass die Reinigungsvorrichtung zum Bewegen des separaten Schutzschildes verwendet werden kann.The object of the invention is solved by the characterizing part of the main claim. The invention makes use of the solution known from DE-C-186934 and has only an apparent disadvantage when the separate protective shield requires an operating mechanism. Usually, however, each machine for coke pressing is not only provided with a door lifting device, but also with a door cleaning device. Surprisingly, however, the contamination of the oven door sealing surfaces is so low that the cleaning device can be used to move the separate protective shield.

Der besondere Vorteil der erfindungsgemässen Konstruktion ist insbesondere die völlige Entlastung der Trüdichtung von der im Ofen stehenden Kohleschüttung. Die Türdichtung kann damit fast als dünne Folie ausgelegt werden.The particular advantage of the construction according to the invention is in particular the complete relief of the door seal from the coal bed standing in the furnace. The door seal can thus almost be designed as a thin film.

Die Ansprüche 2 und 3 stellen zweckmässige Ausführungsformen und Weiterbildungen der Merkmale des Hauptanspruches dar.Claims 2 and 3 represent expedient embodiments and developments of the features of the main claim.

Durch die Ausbildung des Schutzschildes als sogenanntes Hohlprofil, welches aus zwei mit Abstand zum Türkörper gehaltenen Formprofilen besteht, die mit geringem Abstand voneinander angeordnet sind, und einen senkrechten Gasabzugskanal bilden, werden wesentliche Verbesserungen erreicht. Neben dem Gasabzugskanal zwischen Türkörper und dem äusseren zum Türkörper hin gerichteten Formprofil wird zwischen den beiden Formprofilen ein zusätzlicher Gasabzugskanal gebildet. Das Gas kann dabei durch den unteren offenen Querschnitt und über die Höhe verteilt durch Schlitze an den Schmalseiten zwischen den beiden Formprofilen in den Gasabzugskanal eintreten und gelangt über den oberen offenen Querschnitt in den Gassammelraum oberhalb der Kohleschüttung.By designing the protective shield as a so-called hollow profile, which consists of two molded profiles held at a distance from the door body, which are arranged at a short distance from one another, and form a vertical gas discharge duct, significant improvements are achieved. In addition to the gas exhaust duct between the door body and the outer molded profile directed towards the door body, an additional gas exhaust duct is formed between the two molded profiles. The gas can enter the gas discharge duct through the lower open cross section and distributed over the height through slots on the narrow sides between the two shaped profiles and reaches the gas collecting space above the coal bed via the upper open cross section.

Durch die Ausbildung des Schutzschildes als Hohlprofil wird im Vergleich zu den bisher bekannten ebenen Schutzschilden eine sehr viel höhere Festigkeit erreicht.By designing the protective shield as a hollow profile, a much higher strength is achieved compared to the previously known flat protective shields.

Die Wandstärke der Formprofile kann erheblich dünner sein, so dass bei etwa gleicher Biegesteifigkeit das erfindungsgemässe Schutzschild insgesamt leichter ausgeführt sein kann als die bisherigen ebenen Platten.The wall thickness of the shaped profiles can be considerably thinner, so that, with approximately the same bending stiffness, the protective shield according to the invention can be made lighter overall than the previous flat plates.

Es hat sich schliesslich auch gezeigt, dass durch die erfindungsgemässe Form des Schutzschildes eine bessere Wärmeisolierung erreicht wird. Da die meisten heissen Rohgase durch den Gasabzugskanal zwischen den beiden Formprofilen nach oben abgeleitet werden, gelangt nur noch ein geringerer Rohgasanteil in den Gasabzugskanal zwischen Türkörper und dem äusseren Formprofil. Es entsteht dadurch ein deutlicher Temperaturunterschied zwischen dem Gasabzugskanal zwischen den Hohlprofilen und dem äusseren Gasabzugskanal zwischen Türkörper und Formprofil. Insgesamt sind dadurch die Temperaturen am Türkörper erheblich geringer geworden, so dass entweder weniger Isoliermaterial am Türkörper notwendig wird oder die Wärmeabstrahlung nach aussen verringert wird.Finally, it has also been shown that better heat insulation is achieved by the shape of the protective shield according to the invention. Since most of the hot raw gases are discharged upwards through the gas exhaust duct between the two shaped profiles, only a smaller proportion of raw gas gets into the gas exhaust duct between the door body and the outer molded profile. This results in a clear temperature difference between the gas exhaust duct between the hollow profiles and the outer gas exhaust duct between the door body and the molded profile. Overall, the temperatures on the door body have become considerably lower, so that either less insulating material on the door body is necessary or the heat radiation to the outside is reduced.

Durch die erfindungsgemässe spiegelsymmetrische Ausbildung der Formprofile des Schutzschildes wird eine besonders hohe Formstabilität des Schutzschildes auch bei höheren Temperaturen erreicht. Einer eventuellen Verformung und Ausbeulung des inneren, einerseits von der kalten Kohle und andererseits vom kalten Koks berührten Formprofils, wirkt das zum Türkörper hin gerichtete Gegenprofil entscheidend entgegen, so dass eine Verformung des Schutzschildes insgesamt verhindert wird bzw. in erträglichen Grenzen bleibt.Due to the mirror-symmetrical design of the protective profile according to the invention, a particularly high dimensional stability of the protective shield is achieved even at higher temperatures. A possible deformation and bulge of the inner, on the one hand from the cold coal and on the other hand from the cold coke, is counteracted by the counter profile directed towards the door body, so that deformation of the protective shield is prevented as a whole or remains within tolerable limits.

Durch die Verwendung von handelsüblichen Stahlspundwänden in Normalausführung oder Leichtprofilen oder Tafelprofilen für die Formprofile werden die Kosten für das erfindungsgemässe Schutzschild sehr gering gehalten.The cost of the protective shield according to the invention is kept very low through the use of standard steel sheet piling in normal design or light profiles or sheet profiles for the shaped profiles.

Es hat sich erfindungsgemäss als günstig erwiesen, die Formprofile über der gesamten Höhe des Schutzschildes parallel zueinander anzuordnen. Darüber hinaus kann insbesondere der Abstand zwischen den Formprofilen durch auswechselbare, gleichmässig über die Höhe der Formprofile verteilte Abstandshalter veränderbar sein. Je nach den betriebsüblichen Gegebenheiten können dadurch die Gasabzugsmengen in dem Gasabzugskanal zwischen den beiden Formprofilen geregelt werden. Es lässt sich dabei insgesamt die Dicke des Türstopfens bzw. die effektive Kohlenfüllung in der Kammer verändern. Da die Wärmeabstrahlung des Türkörpers nach aussen naturgemäss auch von der Dicke des Türstopfens abhängt, lässt sich auch durch die Veränderung der Abstandshalter zwischen den beiden Formprofilen eine bestimmte gewünschte oder zulässige Temperatur aussen am Türkörper einstellen. Andererseits kann man erfindungsgemäss auch bei gleichbleibender Stärke des Türstopfens die mittleren freien Abstände zwischen den beiden Formprofilen und zwischen Türkörper und dem äusseren Formprofil in gleichem oder entgegengesetztem Sinne verändern und dadurch die Strömungsverhältnisse in den beiden Gasabzugskanälen optimieren.It has proven advantageous according to the invention to arrange the shaped profiles parallel to one another over the entire height of the protective shield. In addition, in particular the distance between the shaped profiles can be changed by interchangeable spacers distributed uniformly over the height of the shaped profiles. Depending on the operational conditions, the gas discharge quantities in the gas discharge duct can be regulated between the two shaped profiles. The overall thickness of the door plug or the effective coal filling in the chamber can be changed. Since the heat radiation from the door body naturally also depends on the thickness of the door plug, the distance can also be changed between the two shaped profiles, set a certain desired or permissible temperature on the outside of the door body. On the other hand, according to the invention, the mean free distances between the two shaped profiles and between the door body and the outer shaped profile can be changed in the same or opposite sense, and the flow conditions in the two gas discharge channels can thereby be optimized, even if the thickness of the door plug remains the same.

Zur Abdichtung der Abstände zwischen den Formprofilen und den angrenzenden Kammerwänden hat es sich erfindungsgemäss als günstig erwiesen, an den Seiten der beiden Formprofile ein oder mehrere schmale Dichtflächen beweglich zu befestigen, die sich beim Absenken der Formprofile an die Kammerwände anlegen. Dabei können besondere Dichtbleche mit schräg ansteigenden Langlöchern versehen sein, durch die die Bolzen bzw. die Abstandshalter zwischen den beiden Formprofilen hindurchgeführt sind. Zur einfacheren Auswechslung der Dichtbleche können sie erfindungsgemäss seitliche zur Kammermitte hin offene Schlitze besitzen zum Anhängen auf die Bolzen bzw. Abstandshalter.To seal the distances between the molded profiles and the adjacent chamber walls, it has proven to be advantageous according to the invention to movably attach one or more narrow sealing surfaces on the sides of the two molded profiles, which contact the chamber walls when the molded profiles are lowered. Special sealing plates can be provided with obliquely rising elongated holes through which the bolts or the spacers between the two shaped profiles are passed. To simplify the replacement of the sealing plates, according to the invention they can have slits which are open at the side towards the middle of the chamber and can be attached to the bolts or spacers.

Einzelne formbeschädigte Dichtbleche können damit ohne zusätzlichen Montageaufwand ausgewechselt werden.Individual form-damaged sealing sheets can thus be replaced without additional installation work.

Um ein einwandfreies Einsetzen der Koksofentür mit dem erfindungsgemässen Schutzschild zu gewährleisten, hat es sich als günstig erwiesen, dass die Dichtbleche im angehobenen Zustand der Formprofile in den Längslöchern oder Schlitzen seitlich nach innen sich bewegen. Wenn die Unterkanten der Dichtbleche im angehobenen Zustand unten über die Formprofile hinausragen, können sie sich beim Absenken der Formprofile gegenüber diesen in senkrechter und aufgrund der schrägen Schlitze bzw. Langlöcher nach aussen auf die Kammerwände zubewegen. Dadurch wird im eingesetzten Zustand der Tür eine zusätzliche Abdichtung gegenüber den Kammerwänden erreicht.In order to ensure a correct insertion of the coke oven door with the protective shield according to the invention, it has proven to be advantageous for the sealing plates to move laterally inwards in the elongated holes or slots in the shaped profiles. If the lower edges of the sealing plates protrude below the molded profiles in the raised state, they can move outwards towards the chamber walls when the molded profiles are lowered relative to them in a vertical direction and due to the oblique slots or elongated holes. This results in an additional seal against the chamber walls when the door is in use.

Die Dichtbleche können erfindungsgemäss an ihren senkrechten Längskanten umgebogen sein. Im waagrechten Schnitt durch ein Dichtblech können diese insbesondere S-förmig ausgebildet sein.According to the invention, the sealing plates can be bent over on their vertical longitudinal edges. In a horizontal section through a sealing plate, they can be S-shaped in particular.

Schliesslich ist es besonders günstig, wenn erfindungsgemäss die innere zur Kammermitte gerichtete Seite der Dichtbleche an dem äusseren Formprofil anliegt. Damit kann zwar das Gas durch den senkrechten Spalt zwischen Kammerwand und innerem Formprofil in den Gasabzugskanal zwischen den beiden Formprofilen eindringen, in den äusseren Gasabzugskanal zwischen Türkörper und dem äusseren Formprofil kann das Rohgas aber aufgrund der Abdichtung der Dichtbleche an den Kammerwänden einerseits und dem äusseren Formprofil andererseits, nur sehr bedingt eindringen.Finally, it is particularly favorable if, according to the invention, the inner side of the sealing plates directed towards the center of the chamber bears against the outer shaped profile. This means that the gas can penetrate through the vertical gap between the chamber wall and the inner molded profile into the gas discharge duct between the two molded profiles, but the raw gas can enter the outer gas discharge duct between the door body and the outer molded profile due to the sealing of the sealing plates on the chamber walls on the one hand and the outer molded profile on the other hand, penetrate only to a very limited extent.

Die Erfindung wird anhand der beigefügten Figuren näher erläutert.

In den Figuren ist mit 1 die Ofenkammer mit den zugehörigen Heiz- oder Kammerwänden angedeutet. Um die senkrechte Öffnung der Ofenkammer 1 herum verläuft der Türrahmen 7, an dem die Elemente 6 der eingesetzten Tür anliegen. Die Koksofentür besteht, wie z. B. in der DE-A-3327337 beschrieben, aus einem Türkörper, der als Hohlprofil entlang dem Türrahmen verläuft und über Verriegelungseinrichtungen mit dem Türrahmen verbunden ist. Mit dem Türkörper 3 ist eine Dichtungsplatte 5, 5a verbunden, die am Umfang des Türrahmens über federbelastete Schrauben 4 gegen den Türrahmen gepresst ist. Zur Verbesserung der Wärmeisolierung nach aussen hin kann die Dichtungsplatte als Hohlprofil ausgebildet sein, wobei das Hohlprofil mit Isolierung ausgefüllt sein kann. Dabei kann die Dichtungsplatte mit einer einseitigen Ausbuchtung (vgl. Fig. 1) oder auch sowohl zur Kammerseite als auch nach aussen hin (vgl. Fig. 7) ausgebeult sein. An der Innenseite der Dichtungsplatte 5, 5a sind über der Höhe verteilt Winkeleisen 15 befestigt, die über Schrauben 16 mit weiteren Winkeleisen 14 verschraubt sind, die wiederum mit den äusseren Formprofilen 9 des Schutzschildes verbunden sind. An diesem äusseren Formprofil 9 ist spiegelbildlich das Formprofil 8 über Bolzen 13 mit Abstandhaltern 12 befestigt. In den Fig. 1 und 2 sind mit 18, 19 in gestrichelter Form die Positionen der Formprofile in grösserem Abstand voneinander dargestellt. In den Fig. 4 und 5 ist ebenfalls der Unterschied zwischen geringerem und grösserem Abstand der Formprofile voneinander deutlich gemacht.In the figures, the furnace chamber with the associated heating or chamber walls is indicated by 1. Around the vertical opening of the furnace chamber 1 runs the door frame 7, against which the elements 6 of the inserted door rest. The coke oven door is such. B. described in DE-A-3327337, from a door body which runs as a hollow profile along the door frame and is connected to the door frame via locking devices. A sealing plate 5, 5a is connected to the door body 3 and is pressed against the door frame at the periphery of the door frame by spring-loaded screws 4. To improve the thermal insulation towards the outside, the sealing plate can be designed as a hollow profile, the hollow profile being able to be filled with insulation. The sealing plate can be bulged with a one-sided bulge (cf. FIG. 1) or both to the chamber side and to the outside (cf. FIG. 7). On the inside of the sealing plate 5, 5a are distributed angle iron 15 attached above the height, which are screwed by screws 16 to other angle iron 14, which in turn are connected to the outer shape profiles 9 of the protective shield. On this outer shape profile 9, the shape profile 8 is attached in a mirror image by bolts 13 with spacers 12. 1 and 2, the positions of the shaped profiles are shown at a greater distance from one another at 18, 19 in dashed form. 4 and 5, the difference between the smaller and larger distance of the shaped profiles from one another is also made clear.

In der Fig. 3 sind eine Reihe von möglichen Ausführungsformen der Formprofile dargestellt. Während gemäss Fig. 1 die Formprofile aussen verbunden sind und in der Mitte liegende Flächen parallel nach aussen ausgelenkt sind, ist gemäss Fig. 3.1 gerade umgekehrt, wobei in Fig. 3.1 die Profile in der Mitte einen geringen Abstand haben und dort über die Bolzen 13 miteinander verbunden sind, während sie aussen zu den Kammerwänden hin einen grossen Abstand haben. Dieser Abstand aussen kann gemäss Fig. 3.1 aussen wieder in parallelen ebenen Wänden enden. Die Formprofile können auch zu den Kammerwänden hin kreisbogenförmig oder gemäss Fig. 3.6 eckig nach aussen abgebogen sein. Gemäss Fig. 3.7 sind die Enden zunächst kreisbogenförmig nach aussen und dann wiederum halkreisförmig nach innen gebogen, so dass die Enden aufeinander zugerichtet sind. Die Fig. 3.1 bis 3.4 enthalten darüber hinaus verschiedene mittlere Ausbuchtungen, die nach aussen dreieckförmig, halbkreisförmig trapezähnlich ausgebildet sind.3 shows a number of possible embodiments of the shaped profiles. While the shaped profiles are connected on the outside according to FIG. 1 and the surfaces lying in the middle are deflected parallel outwards according to FIG. 3.1, the reverse is true according to FIG. 3.1, with the profiles having a small distance in the center and there via the bolts 13 are connected to each other while they are at a large distance from the outside of the chamber walls. According to FIG. 3.1, this distance outside can again end in parallel flat walls. The shaped profiles can also be curved in the form of a circular arc towards the chamber walls or angularly bent outwards according to FIG. 3.6. According to FIG. 3.7, the ends are initially curved outwards in the form of a circular arc and then again inwards in the form of a circular circle, so that the ends are directed towards one another. 3.1 to 3.4 also contain various middle bulges, which are triangular, semicircular-like trapezoidal on the outside.

Aus den Fig. 6 und 7 sind schliesslich die zusätzlichen Dichtbleche 24 ersichtlich, die mit Langlöchern 25 versehen sind. In der Fig. 6 ist in der linken Hälfte der gehobene Zustand der Formprofile dargestellt. Das Dichtblech 25 hat sich von der Kammerwand 2 abgesetzt und ist von der Druckfeder 26 nach innen und nach unten gedrückt worden. Unterhalb des Formprofiles steht es über. Im rechten gesenkten Zustand der Formprofile stehen Formprofile und Dichtbleche auf der Ofensohle auf, und das Dichtblech liegt an der Kammerwand 2 an. Die Relativbewegung Formprofil gegenüber dem Dichtblech kann bis zu 60 mm betragen, wobei der senkrechte Spalt zwischen Formprofil und der Kammerwand bis zu 10 mm betragen kann. Aus der Fig. 7 ist schliesslich die S-förmige Gestalt des Dichtbleches 24 ersichtlich, wobei die Dichtbleche innen an dem äusseren Formprofil 9 anliegen und aussen zwischen dem Formprofil 8 und dem Dichtblech ein senkrechter schmaler Spalt verbleibt.6 and 7 finally show the additional sealing plates 24 which are provided with elongated holes 25. 6, the raised state of the shaped profiles is shown in the left half. The sealing plate 25 has separated from the chamber wall 2 and is pressed inwards and downwards by the compression spring 26 the. It protrudes below the shape profile. In the right lowered state of the shaped profiles, shaped profiles and sealing plates stand on the furnace sole, and the sealing plate lies against the chamber wall 2. The relative movement of the shaped profile with respect to the sealing plate can be up to 60 mm, the vertical gap between the shaped profile and the chamber wall being up to 10 mm. Finally, the S-shaped shape of the sealing plate 24 can be seen from FIG. 7, the sealing plates resting against the inside of the outer shaped profile 9 and a vertical narrow gap remaining outside between the shaped profile 8 and the sealing plate.

Nach Fig. 8 und 9 ist anstelle des Kammerrahmens 7 ein Kammerrahmen 30 vorgesehen. Der Kammerrahmen 30 besitzt innen Nocken 31 mit gabelförmigen Ausnehmungen, in die Riegel 27 eingelegt sind. Die Riegel 27 tragen das Formprofil 18, 19, das vorher vom Türkörper 3 gehalten worden ist.8 and 9, a chamber frame 30 is provided instead of the chamber frame 7. The chamber frame 30 has cams 31 on the inside with fork-shaped recesses into which bolts 27 are inserted. The bolts 27 carry the shaped profile 18, 19 which was previously held by the door body 3.

Nach Fig. 8 und 9 verhindert diese Anordnung eine Kraftentfaltung der Kohleschüttung im Ofen auf den Türkörper 28. Der Türkörper muss demzufolge nur noch dem Gasdruck im Ofen standhalten. Die Dichtungsplatte 29 kann infolgedessen eine minimale Dicke aufweisen, d. h. ähnlich einer Folie ausgebildet sein.According to FIGS. 8 and 9, this arrangement prevents the coal bed in the furnace from developing its force on the door body 28. The door body therefore only has to withstand the gas pressure in the furnace. As a result, the sealing plate 29 can have a minimal thickness, i. H. be designed similar to a film.

Zum Koksdrücken wird der Türkörper 28 - wie üblich -von der Türhebevorrichtung ergriffen und zurückgeschwenkt. Die Formprofile 18, 19 werden von der mit entsprechenden Klauen versehenen Türreinigungsvorrichtung an den Riegeln 27 erfasst, aus dem Ofenrahmen herausgehoben und zurückgeschwenkt. Die Türreinigungsvorrichtung steht aufgrund geringer Verschmutzungsneigung und entsprechend geringer Reinigungstätigkeit dazu zur Verfügung.For coke pressing, the door body 28 is gripped by the door lifting device and pivoted back as usual. The shaped profiles 18, 19 are gripped by the door cleaning device provided with corresponding claws on the bolts 27, lifted out of the furnace frame and pivoted back. The door cleaning device is available due to the low tendency to contamination and correspondingly low cleaning activity.

Claims (3)
