Definitions
- the invention relates to a cleaning device for cleaning an oven door of a coking chamber of a coke oven according to the preamble of claim 1.
- a Kokereiofentrlick is known with a pair of radial cutter and a jet nozzles having high-pressure cleaning device, wherein a vertical frame is provided with a movable cleaning slide for the nozzles and the radial cutter, the cleaning slide has a cleaning area whose length corresponds to about a quarter of the door height and the jet nozzles at least are provided at the upper and at the lower end portion of the cleaning slide.
- the JP - A - 2001115164 and the JP - A - 2000319660 each discloses a cleaning device with a cleaning carriage having a cleaning area with a length that is less than half the height of the coke oven door. Abrasives and nozzles are provided on the cleaning slide.
- Another possibility for cleaning the oven door consists in the use of a high-pressure cleaning device, in which in particular water is applied via nozzles to the area to be cleaned.
- Such high pressure cleaning equipment are known both for cleaning the door plug and the sealing cutting area.
- the disadvantage is that comparatively much water is obtained in an exclusive high-pressure cleaning, which not only leads to a high water consumption, but also increases the risk of accidents, especially in winter by ice formation.
- Another major disadvantage of high-pressure cleaning is that the risk of damage to the sealing cutting area exists due to the high pressures that occur.
- An effective high-pressure cleaning of the sealing cutting area requires that the steel emerging from the nozzles is under a correspondingly high pressure. The higher the pressure, the better the cleaning effect.
- a generic cleaning device in which both a mechanical removal device and a high pressure cleaning device is used.
- the known cleaning device has on opposite sides of a support frame in each case a carriage, on which both bevel cutters and nozzle holders are provided.
- Each nozzle holder has two nozzles for high-pressure water, which cleans the sealing area.
- the known cleaning device has several disadvantages. Since only two relatively small carriages are used, the door cleaning takes a comparatively long time. In addition, the problem described above also occurs in the sealing cutting area due to the high-pressure cleaning in this known cleaning device.
- the object of the present invention is therefore to avoid the disadvantages occurring in the prior art.
- An essential advantage of the present invention is that when using high-pressure rotating nozzles results in an excellent cleaning result in the seal cutting area.
- the rotating nozzles make it possible to work with very high pressures. As the nozzles rotate, it is prevented that a high pressure steel is permanently directed to a specific location.
- the rotating high-pressure nozzles protect the sealing edge of the oven door, because unlike flat or round nozzles, which have a rigid arrangement, no or at least a significantly reduced cutting action is given at the same pressure.
- the risk of damage to the sealing edge by the high-pressure medium is considerably reduced, even if the high-pressure cleaning device remains at one point during the cleaning process for a long time.
- the advantages of low water consumption result in the cleaning device according to the invention, since the area cleaned by the mechanical removal device does not have to be additionally cleaned via the high-pressure cleaning device. Associated with the low water consumption is also a lower environmental impact and a reduced risk of accidents, since ultimately less water is produced and thus the formation of ice in winter is reduced.
- the cleaning medium in rotating high-pressure nozzles, can be supplied with a pressure of more than 50 bar.
- the cleaning medium is supplied at a pressure between 100 bar and 400 bar. With such a pressure when using high-pressure nozzles damages of the sealing edge are not expected, while an excellent cleaning effect is achieved in the seal cutting area.
- the rotating high-pressure nozzles should preferably rotate at a speed of greater than 500 rpm, preferably between 1000 and 4500 rpm, in order to achieve the good cleaning effect in the sealing cutting area on the one hand and the reduced risk of damage to the sealing blade.
- the nozzles used there are designed either as rigid nozzles or as rotating nozzles.
- the use of rigid nozzles in this area it is therefore easily possible because the risk of damage to the aforementioned door area or the door plug part at the same pressure of the cleaning medium is considerably lower than the sealing edge.
- the cleaning device according to the invention has a mechanical removal device.
- the removal device can have at least one known from the prior art mechanical removal means, such as a scraper, a scraper, a knife, a scratch and / or a milling cutter. Since the removal agent acts directly on the door stopper for cleaning, the removal means are resiliently mounted in order to avoid damage to the door stopper and / or the removal means.
- a support frame with at least one guided on the support frame movable cleaning slide for the nozzles and / or the removal device is provided. It is preferred that the nozzles and the removal device are provided on a common cleaning slide.
- the cleaning carriage should preferably be designed such that the oven door can be cleaned on both longitudinal sides, so that on both sides nozzles and Abtragsstoff the removal device are provided. It has been found that the cleaning carriage for cleaning at a rate of greater than 20 mm per second, preferably between 25 and 125 mm per Second and in particular between 50 and 100 mm per second should be moved.
- the cleaning carriage not only covers a small area of the height of the door, but has a cleaning area with a length which is slightly greater than half the door height of the door ,
- a removal means of the removal device and nozzles of the high-pressure cleaning device should be provided at the cleaning area of the cleaning carriage.
- This embodiment has the advantage that only a very small number of ablation means and nozzles is required to sufficiently clean the longitudinal sides of the oven door.
- the cleaning carriage is in the lower position as the starting position, the lower half is cleaned when the cleaning carriage is raised by the removal means provided in the lower end region.
- the upper area of the oven door is cleaned by the detergent provided at the upper end of the cleaning area when the cleaning slide is raised.
- the abovementioned idea of the invention also has independent significance, that is to say independent of the rotating high-pressure nozzles, the use of which is however particularly preferred.
- the nozzles of the upper and / or lower end region and / or the nozzles of an end region can be controlled separately from one another.
- Procedure of the cleaning slide initially only for example to activate the nozzles of the lower end for cleaning.
- the door plug area is completely cleaned mechanically via the mechanical removal means.
- the nozzles are then activated in the upper end, so that after the lowering of the cleaning slide and the upper seal cutting area is cleaned.
- a longitudinal cleaning is carried out on the oven door via the means described above.
- at least one nozzle of the high-pressure cleaning device is provided at the upper and lower door plug area and / or at the sealing cutting area.
- a rotating high pressure nozzle should be used. Since the upper and lower end regions are relatively short, this region including the sealing cutting region can be cleaned exclusively by high-pressure cleaning, since the water requirement for cleaning the relatively narrow upper and lower end surface is relatively small.
- the support frame is at least partially housed.
- the enclosure preferably includes lateral, over the height of the support frame extending protective covers.
- the cleaning device according to the invention can be provided both stationary on the coke oven or on a coke oven operating machine. Accordingly, the present invention relates to both a coke oven machine and a coke oven, each with a cleaning device of the aforementioned type.

Abstract
Description
Die Erfindung betrifft eine Reinigungsvorrichtung zur Reinigung einer Ofentür einer Verkokungskammer eines Koksofens nach dem Oberbegriff des Anspruchs 1.The invention relates to a cleaning device for cleaning an oven door of a coking chamber of a coke oven according to the preamble of
Aus der
Die
Bei der Verkokung schlagen sich im Koksofengas befindliche Bestandteile innenseitig an den Ofentüren der Verkokungskanunem nieder. Um eine hinreichende Dichtigkeit der Ofentüre beim Verkokungsvorgang gewährleisten zu können, ist es erforderlich, die Ofentüren zu reinigen. Zur Reinigung von Ofentüren ist es bekannt, mechanische Abtragseinrichtungen wie Schaber, Abstreifer, Messer, Kratzer oder auch Fräser anzusetzen. Derartige mechanische Abtragsmittel werden allerdings üblicherweise nur zur Reinigung des Türstopfens verwendet. Zur Reinigung des vergleichsweise empfindlichen Dichtschneidenbereichs sind derartige mechanische Abtragsmittel nicht geeignet.During coking, constituents present in the coke oven gas are deposited on the inside of the oven doors of the coking cans. In order to ensure a sufficient tightness of the oven door during the coking process, it is necessary to clean the oven doors. For cleaning oven doors, it is known to apply mechanical abrasion devices such as scrapers, scrapers, knives, scratches or milling cutters. However, such mechanical abrasives are usually used only for cleaning the door plug. For cleaning the comparatively sensitive sealing cutting area, such mechanical removal means are not suitable.
Eine andere Reinigungsmöglichkeit der Ofentür besteht in der Verwendung einer Hochdruckreinigungseinrichtung, bei der insbesondere Wasser über Düsen auf den zu reinigenden Bereich aufgebracht wird. Derartige Hochdruckreinigungseinrichtungen sind sowohl zur Reinigung des Türstopfens als auch des Dichtschneidenbereichs bekannt. Von Nachteil ist jedoch, daß bei einer ausschließlichen Hochdruckreinigung vergleichsweise viel Wasser anfällt, was nicht nur zu einem hohen Wasserverbrauch führt, sondern auch die Unfallgefahr insbesondere im Winter durch Eisbildung erhöht. Ein weiterer wesentlicher Nachteil der Hochdruckreinigung besteht darin, daß durch die auftretenden hohen Drücke die Gefahr einer Beschädigung des Dichtschneidenbereichs besteht. Eine wirksame Hochdruckreinigung des Dichtschneidenbereichs setzt voraus, daß der aus den Düsen austretende Stahl unter einem entsprechend hohen Druck steht. Je höher der Druck ist, desto besser ist dabei die Reinigungswirkung. Allerdings führt ein zu hoher Druck des Reinigungsmediums dazu, daß die Dichtschneide beim Reinigen beschädigt wird. Die Gefahr einer Beschädigung der Dichtschneide besteht insbesondere dann, wenn bei einem sehr hohen Druck der Schlitten für kurze Zeit an der gleichen Stelle verbleibt und dann die Dichtschneide einer dauerhaften Druckbelastung unterliegt.Another possibility for cleaning the oven door consists in the use of a high-pressure cleaning device, in which in particular water is applied via nozzles to the area to be cleaned. Such high pressure cleaning equipment are known both for cleaning the door plug and the sealing cutting area. The disadvantage, however, is that comparatively much water is obtained in an exclusive high-pressure cleaning, which not only leads to a high water consumption, but also increases the risk of accidents, especially in winter by ice formation. Another major disadvantage of high-pressure cleaning is that the risk of damage to the sealing cutting area exists due to the high pressures that occur. An effective high-pressure cleaning of the sealing cutting area requires that the steel emerging from the nozzles is under a correspondingly high pressure. The higher the pressure, the better the cleaning effect. However, too high a pressure of the cleaning medium causes the sealing blade to be damaged during cleaning. The risk of damage to the sealing edge exists in particular if, at a very high pressure, the carriage remains in the same position for a short time and then the sealing blade is subjected to a permanent pressure load.
Um den Wasserverbrauch zu verringern, ist aus der
Die bekannte Reinigungsvorrichtung hat verschiedene Nachteile. Da lediglich zwei relativ kleine Schlitten verwendet werden, dauert die Türreinigung vergleichsweise lange. Darüber hinaus tritt im Dichtschneidenbereich aufgrund der Hochdruckreinigung die zuvor beschriebene Problematik bei dieser bekannten Reinigungsvorrichtung ebenfalls auf.The known cleaning device has several disadvantages. Since only two relatively small carriages are used, the door cleaning takes a comparatively long time. In addition, the problem described above also occurs in the sealing cutting area due to the high-pressure cleaning in this known cleaning device.
Aufgabe der vorliegenden Erfindung ist es nun, die beim Stand der Technik auftretenden Nachteile zu vermeiden.The object of the present invention is therefore to avoid the disadvantages occurring in the prior art.
Die vorgenannte Aufgabe wird durch die Merkmale einer Reinigungsvorrichtung gemäß Anspruch 1 gelöst. Durch die Erfindung ergeben sich einige wesentliche Vorteile. Ein wesentlicher Vorteil der vorliegenden Erfindung liegt darin, daß sich bei Verwendung von rotierenden Hochdruckdüsen ein ausgezeichnetes Reinigungsergebnis im Dichtschneidenbereich ergibt. Durch die rotierenden Düsen ist es möglich, mit sehr hohen Drücken zu arbeiten. Da die Düsen rotieren, wird verhindert, daß auf eine ganz bestimmte Stelle dauerhaft ein Hochdruckstahl gerichtet ist. Letztlich schonen die rotierenden Hochdruck-Düsen die Dichtschneide der Ofentür, da anders als bei Flach- oder Runddüsen, die eine starre Anordnung haben, keine oder jedenfalls eine erheblich verringerte Schneidwirkung bei gleichem Druck gegeben ist. Hierdurch wird die Gefahr einer Beschädigung der Dichtschneide durch das Hochdruckmedium erheblich verringert, und zwar auch dann, wenn die Hochdruckreinigungseinrichtung beim Reinigungsvorgang über längere Zeit an einer Stelle verbleibt. Darüber hinaus ergeben sich bei der erfindungsgemäßen Reinigungsvorrichtung die Vorteile des geringen Wasserverbrauchs, da der von der mechanischen Abtragseinrichtung gereinigte Bereich nicht noch zusätzlich über die Hochdruckreinigungseinrichtung gereinigt werden muß. Verbunden mit dem geringen Wasserverbrauch ist auch eine geringere Umweltbelastung und eine verringerte Unfallgefahr, da letztlich weniger Wasser anfällt und damit die Eisbildung im Winter verringert ist.The above object is achieved by the features of a cleaning device according to
Im Zusammenhang mit der vorliegenden Erfindung ist festgestellt worden, daß bei rotierenden Hochdruckdüsen das Reinigungsmedium mit einem Druck von mehr als 50 bar zugeführt werden kann. Vorzugsweise wird das Reinigungsmedium mit einem Druck zwischen 100 bar und 400 bar zugeführt. Bei einem derartigen Druck sind bei Verwendung von Hochdruckdüsen Beschädigungen der Dichtschneide nicht zu erwarten, während eine hervorragende Reinigungswirkung im Dichtschneidenbereich erzielt wird.In connection with the present invention, it has been found that in rotating high-pressure nozzles, the cleaning medium can be supplied with a pressure of more than 50 bar. Preferably, the cleaning medium is supplied at a pressure between 100 bar and 400 bar. With such a pressure when using high-pressure nozzles damages of the sealing edge are not expected, while an excellent cleaning effect is achieved in the seal cutting area.
Die rotierenden Hochdruckdüsen sollten vorzugsweise mit einer Drehzahl von größer 500 U/min, vorzugsweise zwischen 1000 bis 4500 U/min rotieren, um die gute Reinigungswirkung im Dichtschneidenbereich einerseits und die verringerte Beschädigungsgefahr an der Dichtschneide zu erzielen.The rotating high-pressure nozzles should preferably rotate at a speed of greater than 500 rpm, preferably between 1000 and 4500 rpm, in order to achieve the good cleaning effect in the sealing cutting area on the one hand and the reduced risk of damage to the sealing blade.
In Verbindung mit der vorliegenden Erfindung bietet es sich an, über die Hochdruckreinigungseinrichtung nicht nur den Dichtschneidenbereich, sondern auch den Türbereich zwischen der Dichtschneide und dem Türstopfen zu reinigen. Des weiteren kann auch zumindest der dem Türbereich benachbarte Türstopfenteil über die Hochdruckreinigungseinrichtung gereinigt werden. Dies gilt insbesondere bei Türstopfen, die seitlich nicht nur eine sondern zwei oder mehr Flächen aufweisen.In connection with the present invention, it is advisable to clean not only the sealing cutting area, but also the door area between the sealing edge and the door stopper via the high-pressure cleaning device. Furthermore, at least the door area adjacent to the door area can also be cleaned via the high-pressure cleaning device. This applies in particular to door stoppers which have not only one but two or more surfaces laterally.
Im Zusammenhang mit der Reinigung des vorgenannten Türbereichs und des dem Türbereich benachbarten Türstopfenteils durch die Hochdruckreinigungseinrichtung kann vorgesehen sein, daß die dort verwendeten Düsen entweder als starre oder aber als rotierende Düsen ausgebildet sind. Die Verwendung von starren Düsen in diesem Bereich ist es deshalb problemlos möglich, da die Gefahr der Beschädigung des vorgenannten Türbereichs oder des Türstopfenteil bei gleichem Druck des Reinigungsmediums erheblich geringer ist als bei der Dichtschneide.In connection with the cleaning of the above-mentioned door area and the door stop part adjacent to the door area by the high-pressure cleaning device, it can be provided that the nozzles used there are designed either as rigid nozzles or as rotating nozzles. The use of rigid nozzles in this area, it is therefore easily possible because the risk of damage to the aforementioned door area or the door plug part at the same pressure of the cleaning medium is considerably lower than the sealing edge.
Wie zuvor ausgeführt worden ist, weist die erfindungsgemäße Reinigungsvorrichtung eine mechanische Abtragseinrichtung auf. Die Abtragseinrichtung kann dabei wenigstens ein aus dem Stand der Technik bekanntes mechanisches Abtragsmittel, wie einen Schaber, einen Abstreifer, ein Messer, ein Kratzer und/oder einen Fräser aufweisen. Da das Abtragsmittel unmittelbar am Türstopfen zur Reinigung angreift, sind die Abtragsmittel federnd gelagert, um Beschädigungen am Türstopfen und/oder den Abtragsmittel zu vermeiden.As has been stated above, the cleaning device according to the invention has a mechanical removal device. The removal device can have at least one known from the prior art mechanical removal means, such as a scraper, a scraper, a knife, a scratch and / or a milling cutter. Since the removal agent acts directly on the door stopper for cleaning, the removal means are resiliently mounted in order to avoid damage to the door stopper and / or the removal means.
Um die Reinigung einer Tür in einfacher Weise vornehmen zu können, ist ein Traggerüst mit wenigstens einem am Traggerüst geführten verfahrbaren Reinigungsschlitten für die Düsen und/oder die Abtragseinrichtung vorgesehen. Bevorzugt ist es dabei, daß die Düsen und die Abtragungseinrichtung an einem gemeinsamen Reinigungsschlitten vorgesehen sind. Der Reinigungsschlitten sollte dabei vorzugsweise derart ausgebildet sein, daß die Ofentür an beiden Längsseiten gereinigt werden kann, so daß also beidseitig Düsen und Abtragsmittel der Abtragsvorrichtung vorgesehen sind. Dabei ist festgestellt worden, daß der Reinigungsschlitten zur Reinigung mit einer Geschwindigkeit von größer 20 mm pro Sekunde, vorzugsweise zwischen 25 und 125 mm pro Sekunde und insbesondere zwischen 50 und 100 mm pro Sekunde bewegt werden sollte.In order to be able to carry out the cleaning of a door in a simple manner, a support frame with at least one guided on the support frame movable cleaning slide for the nozzles and / or the removal device is provided. It is preferred that the nozzles and the removal device are provided on a common cleaning slide. The cleaning carriage should preferably be designed such that the oven door can be cleaned on both longitudinal sides, so that on both sides nozzles and Abtragsmittel the removal device are provided. It has been found that the cleaning carriage for cleaning at a rate of greater than 20 mm per second, preferably between 25 and 125 mm per Second and in particular between 50 and 100 mm per second should be moved.
Von besonderem Vorteil ist es in diesem Zusammenhang, wenn der Reinigungsschlitten - im Gegensatz zum Stand der Technik- nicht nur einen kleinen Bereich der Höhe der Tür abdeckt, sondern einen Reinigungsbereich mit einer Länge aufweist, die etwas größer ist als die Hälfte der Türhöhe der Ofentür. Darüber hinaus sollte am Reinigungsbereich des Reinigungsschlittens, vorzugsweise lediglich am oberen Endbereich und am unteren Endbereich, also letztlich oben und unten am Reinigungsbereich, jeweils ein Abtragsmittel der Abtragseinrichtung sowie Düsen der Hochdruckreinigungseinrichtung vorgesehen sein. Diese Ausgestaltung hat den Vorteil, daß nur eine sehr geringe Anzahl von Abtragmitteln und Düsen erforderlich ist, um die Längsseiten der Ofentür hinreichend zu reinigen. Befindet sich der Reinigungsschlitten beispielsweise in der unteren Stellung als Ausgangsposition, wird durch das im unteren Endbereich vorgesehene Abtragmittel die untere Hälfte beim Hochfahren des Reinigungsschlittens gereinigt. Gleichzeitig wird durch die am oberen Ende des Reinigungsbereichs vorgesehenen Reinigungsmittel beim Hochfahren des Reinigungsschlittens der obere Bereich der Ofentür gereinigt.It is particularly advantageous in this context if, in contrast to the prior art, the cleaning carriage not only covers a small area of the height of the door, but has a cleaning area with a length which is slightly greater than half the door height of the door , In addition, at the cleaning area of the cleaning carriage, preferably only at the upper end area and at the lower end area, ie ultimately at the top and bottom of the cleaning area, a removal means of the removal device and nozzles of the high-pressure cleaning device should be provided. This embodiment has the advantage that only a very small number of ablation means and nozzles is required to sufficiently clean the longitudinal sides of the oven door. If, for example, the cleaning carriage is in the lower position as the starting position, the lower half is cleaned when the cleaning carriage is raised by the removal means provided in the lower end region. At the same time, the upper area of the oven door is cleaned by the detergent provided at the upper end of the cleaning area when the cleaning slide is raised.
Der vorgenannten Erfindungsidee kommt im übrigen auch eigenständige Bedeutung zu, also unabhängig von den rotierenden Hochdruckdüsen, deren Verwendung allerdings besonders bevorzugt ist.Incidentally, the abovementioned idea of the invention also has independent significance, that is to say independent of the rotating high-pressure nozzles, the use of which is however particularly preferred.
Im Zusammenhang mit der vorliegenden Erfindung ist festgestellt worden, daß es zur Erzielung einer hinreichenden Reinigung ausreichend ist, sowohl im oberen als auch im unteren Bereich jeweils lediglich ein Abtragmittel, vorzugsweise ein insbesondere federnd gelagertes Messer sowie zwischen zwei und vier Düsen vorzusehen. Durch Verwendung einer derart geringen Anzahl an Düsen kann der entsprechende Hochdruckerzeuger bzw. die diesbezügliche Pumpe entsprechend gering dimensioniert werden.In connection with the present invention, it has been found that it is sufficient to achieve sufficient cleaning, both in the upper and in the lower area only one Abtragmittel, preferably provide a particular spring-mounted blade and between two and four nozzles. By using such a small number of nozzles, the corresponding high-pressure generator or the relevant pump can be dimensioned correspondingly small.
Günstig ist es in diesem Zusammenhang, wenn die Düsen des oberen und/oder unteren Endbereichs und/oder die Düsen eines Endbereichs untereinander separat ansteuerbar sind. Durch eine solche Ausgestaltung ist es möglich, beim Verfahren des Reinigungsschlittens zunächst nur beispielsweise die Düsen des unteren Endbereichs zur Reinigung zu aktivieren. Hierdurch wird im Dichtschneidenbereich lediglich die untere Hälfte gereinigt. Dem gegenüber wird beim Hochfahren des Reinigungsschlittens der Türstopfenbereich mechanisch über die mechanischen Abtragsmittel vollständig gereinigt. Beim Herabfahren des Reinigungsschlittens werden dann die Düsen im oberen Endbereich aktiviert, so daß nach dem Herabfahren des Reinigungsschlittens auch der obere Dichtschneidenbereich gereinigt ist. Auf diese Weise ist es möglich, den äußeren Türstopfenbereich über die mechanische Abtragseinrichtung mehrfach zu bestreichen bzw. zu reinigen, während gleichzeitig der Dichtschneidenbereich über die Hochdruckdüsen nur einmal gereinigt wird, was zur Erzielung eines guten Reinigungsergebnisses hinreichend ist. Daraus resultiert letztlich eine optimale Reinigung bei verringertem Wasserverbrauch.It is favorable in this context if the nozzles of the upper and / or lower end region and / or the nozzles of an end region can be controlled separately from one another. By such a configuration, it is possible at Procedure of the cleaning slide initially only for example to activate the nozzles of the lower end for cleaning. As a result, only the lower half is cleaned in the seal cutting area. On the other hand, when the cleaning slide is raised, the door plug area is completely cleaned mechanically via the mechanical removal means. When descending the cleaning slide the nozzles are then activated in the upper end, so that after the lowering of the cleaning slide and the upper seal cutting area is cleaned. In this way, it is possible to repeatedly brush or clean the outer door plug area via the mechanical removal device, while at the same time the sealing cutting area is cleaned only once via the high-pressure nozzles, which is sufficient to achieve a good cleaning result. This ultimately results in optimal cleaning with reduced water consumption.
Über die zuvor beschriebenen Mittel wird im Ergebnis eine Längsreinigung an der Ofentür durchgeführt. Um auch die obere und unter Stirnfläche der Ofentür bzw. des Türstopfens zu reinigen, ist am oberen und am unteren Türstopfenbereich und/oder am Dichtschneidenbereich wenigstens eine Düse der Hochdruckreinigungseinrichtung vorgesehen. Auch hier sollte eine rotierende Hochdruckdüse verwendet werden. Da der obere und untere Stirnbereich relativ kurz sind, kann dieser Bereich einschließlich des Dichtschneidenbereichs ausschließlich über eine Hochdruckreinigung gereinigt werden, da der Wasserbedarf für die Reinigung der relativ schmalen oberen und unteren Stirnfläche relativ gering ist.As a result, a longitudinal cleaning is carried out on the oven door via the means described above. In order to clean also the upper and under face of the oven door or the door plug, at least one nozzle of the high-pressure cleaning device is provided at the upper and lower door plug area and / or at the sealing cutting area. Again, a rotating high pressure nozzle should be used. Since the upper and lower end regions are relatively short, this region including the sealing cutting region can be cleaned exclusively by high-pressure cleaning, since the water requirement for cleaning the relatively narrow upper and lower end surface is relatively small.
Grundsätzlich ist es möglich, den oberen sowie den unteren Stirnbereich der Ofentür durch stationär angeordnete Düsen zu reinigen. Allerdings ist dann die erforderliche Düsenanzahl vergleichsweise hoch, so daß eine entsprechend groß dimensionierte Pumpe erforderlich ist. Von Vorteil ist es daher, daß zur Querreinigung ein am Traggerüst verfahrbarer weiterer Schlitten vorgesehen ist, an dem wenigstens eine, vorzugsweise zwei Düsen angeordnet sind.In principle, it is possible to clean the upper and the lower end region of the oven door by stationary nozzles. However, then the number of nozzles required is comparatively high, so that a correspondingly large-sized pump is required. It is advantageous, therefore, that for transverse cleaning a movable on the support frame further slide is provided on which at least one, preferably two nozzles are arranged.
Um einen Spritzschutz zur Verfügung zu stellen, ist das Traggerüst zumindest teilweise eingehaust. Die Einhausung umfaßt vorzugsweise seitliche, sich über die Höhe des Traggerüsts erstreckende Schutzabdeckungen.In order to provide a splash guard, the support frame is at least partially housed. The enclosure preferably includes lateral, over the height of the support frame extending protective covers.
Die erfindungsgemäße Reinigungsvorrichtung kann sowohl stationär am Koksofen oder aber auf einer Koksofenbedienungsmaschine vorgesehen sein. Dementsprechend betrifft die vorliegende Erfindung sowohl eine Koksofenmaschine als auch einen Koksofen jeweils mit einer Reinigungsvorrichtung der vorgenannten Art.The cleaning device according to the invention can be provided both stationary on the coke oven or on a coke oven operating machine. Accordingly, the present invention relates to both a coke oven machine and a coke oven, each with a cleaning device of the aforementioned type.
Schließlich betrifft die vorliegende Erfindung ein Verfahren zum Reinigen einer Ofentür einer Verkokungskammer eines Koksofens, wie dies zuvor in Verbindung mit dem Reinigungsbereich beschrieben worden ist, dessen Länge etwas größer ist als die Hälfte der Höhe der Ofentür, so daß sich bei den zu reinigenden Bereichen eine geringe Überdeckung ergibt.Finally, the present invention relates to a method for cleaning an oven door of a coking chamber of a coke oven, as described above in connection with the cleaning area, whose length is slightly greater than half the height of the oven door, so that in the areas to be cleaned low coverage results.

In den einzelnen Figuren ist eine Reinigungsvorrichtung 1 zur Reinigung einer Ofentür 2 einer nicht dargestellten Verkokungskammer eines Koksofens gezeigt. Die Ofentür 2 weist einen Türstopfen 3 und wenigstens eine äußere, umlaufende Dichtschneide 4 auf. Bei dem Türstopfen 3 handelt es sich in der Regel um einen Steinstopfen. Mit der Reinigungsvorrichtung 1 ist eine kombinierte Türreinigung möglich. Die kombinierte Türreinigung ergibt sich durch eine mechanische Abtragseinrichtung 5 zur Abtragsreinigung und eine Düsen 6 aufweisende Hochdruckreinigungseinrichtung 7 zur Hochdruckreinigung. Dabei ist die mechanische Abtragseinrichtung zur Reinigung eines Türstopfenbereichs, nämlich einer Seitenfläche 8 vorgesehen, während die Düsen 6 zumindest zur Reinigung des Dichtschneidenbereichs 4 vorgesehen sind. Im übrigen versteht es sich, daß die Hochdruckreinigungseinrichtung 7 neben den Düsen 6 Hochdruckleitungen 10 sowie eine Pumpeinrichtung bzw. einen Druckerzeuger, der im einzelnen nicht dargestellt ist, aufweist.In the individual figures, a
Vorgesehen ist nun, daß die Hochdruckreinigungseinrichtung 7 rotierende Düsen 6 zur Reinigung des Dichtschneidenbereichs 10 aufweist. Durch die rotierenden Hochdruckdüsen 6 wird Wasser als Reinigungsmedium mit einem Druck von etwa 150 bar zugeführt, wobei die Düsen 6 mit einer Drehzahl von 3000 bis 3500 Umdrehungen pro Minute rotieren.It is now provided that the high
Neben einer Düse 6, die zur Reinigung des Dichtschneidenbereichs vorgesehen ist, wird über weitere Düsen 6 ebenfalls der Türbereich 12 zwischen der Dichtschneide 4 und dem Türstopfen 3 und auch der dem Türbereich 12 benachbarte Türstopfenteil 13 gereinigt. Im dargestellten Ausführungsbeispiel weist der Türstopfen 3 Seitenflächen auf, die jeweils mit zwei zueinander gewinkelten Einzelflächen versehen sind. Gerade in einem derartigen Fall bietet es sich an, lediglich die äußere Seitenfläche 8 über die mechanische Abtragseinrichtung 5 zu reinigen, während die davon abgewinkelte Fläche 13 über die Düsen 6 gereinigt wird. Insbesondere die die Fläche 13 reinigenden Düsen 6 können grundsätzlich auch als starre, also nicht rotierende Düsen ausgebildet sein, da die Gefahr einer Beschädigung des Türstopfen durch die Hochdruckreinigung gering ist.In addition to a
Im dargestellten Ausführungsbeispiel weist die mechanische Abtrageinrichtung 5 mehrere Messer als Abtragsmittel 14 auf, wobei die Messer jeweils federnd an den Stellen 15 gelagert sind.In the illustrated embodiment, the
Im übrigen weist die Reinigungsvorrichtung 1 ein Traggerüst 16 auf. Das Traggerüst 16 weist zwei Vertikalträger 17, 18 sowie zwei Horizontalträger 19 auf. Das Traggerüst 16 bildet dabei einen geschlossenen Rahmen. An den Vertikalträgern 17, 18 des Traggerüstes 16 ist ein Reinigungsschlitten 20 für die Düsen 6 und die Abtragseinrichtung 5 geführt. Der Reinigungsschlitten 20 wird vorliegend über eine Hubeinrichtung 21, die am unteren Horizontalträger 19 gelagert ist, aufwärts und abwärts bewegt. Dabei weist der Schlitten 20 seitlich Führungsrollen 22 auf, die an den einander zugewandten Seitenflächen der Vertikalträger 17, 18 ablaufen. Es versteht sich, daß die Auf- und Abwärtsbewegung des Reinigungsschlittens 20 über beliebige Mittel erfolgen kann. Auch die Anordnung von Führungsrollen 22 am Schlitten 20 ist nicht erforderlich. Eine Führung an den Vertikalträgern 17, 18 kann auch über entsprechende Führungsschienen oder ähnliches erfolgen.Otherwise, the
In jedem Falle ist es bei den dargestellten Ausführungsformen so, daß die Düsen 6 und die Abtragseinrichtung 5 auf einem gemeinsamen Reinigungsschlitten 20 vorgesehen sind. Wie sich dies insbesondere aus den
Im einzelnen ist der Reinigungsschlitten 20 derart ausgebildet, daß er in Draufsicht gesehen eine U-förmige Ausbildung hat. Dabei sind ein zwischen den beiden Vertikalträgern 17, 18 angeordneter Mittelträger 26 und zwei seitliche Seitenträger 27 angeordnet. An den Seitenträgern 27 befinden sich auf beiden Seiten des Türstopfens 3 jeweils die Reinigungsbereiche 23. Auf jeder Seite des Türstopfens 3 befinden sich dabei zwei Seitenträger 27, wobei am Reinigungsbereich 23 in dem Teil zwischen den Seitenträgern 27 keine Reinigungsmittel vorgesehen sind. Unmittelbar im Anschluß an die Seitenträger 27 befinden sich die beiden Abtragsmittel 14, um die auftretenden Kräfte beim Abschaben des Türstopfen 3 besser aufnehmen zu können. Im übrigen sind die beiden Seitenträger 27 einer Seite jeweils über einen Träger 28 miteinander verbunden.In detail, the cleaning
Wie insbesondere die
Im übrigen sind die Hochdruckdüsen 6 über eine entsprechende Steuereinrichtung sowohl einzeln als auch gruppenweise, d. h. für den oberen Endbereich 24 oder aber für den unteren Endbereich 25 ansteuerbar. Es ist also möglich, bedarfsweise lediglich eine Gruppe oder aber auch nur eine einzige Düse 6 anzusteuern.Moreover, the high-
Zur Querreinigung des oberen Türstopfenbereichs 29 und des unteren Türstopfenbereichs 30 sowie des dortigen Dichtschneidenbereichs 10 ist ebenfalls eine Hochdruckreinigung vorgesehen. Hierzu weist das Traggerüst 16 oben und unten jeweils einen weiteren Schlitten 31 auf, der jeweils quer verfahrbar ist. An dem weiteren Schlitten 31 sind vorliegend jeweils zwei rotierende Hochdruckdüsen 6 vorgesehen, wobei eine der Düsen 6 den Dichtschneidenbereich 10 und die andere Düse den Türbereich 12 sowie Teile des benachbarten Türstopfenbezeichs reinigt.For transverse cleaning of the upper
