Description

Die Erfindung betrifft eine Kokseintragsvorrichtung für den Kühlschacht einer Kokstrockenkühlanlage, die aus einem stationären Trichter mit einer Absaugleitung, einem heb- und senkbaren Trichterunterteil und einem verschiebbaren und heb- und senkbaren Kühlschachtverschluß besteht, dem eine Manipuliervorrichtung mit Antrieb zugeordnet ist.The invention relates to a coke entry device for the cooling shaft of a coke dry cooling system, which consists of a stationary funnel with a suction line, a lowerable and lowerable funnel lower part and a movable and liftable and lowerable cooling shaft closure, to which a manipulation device with drive is assigned.

Bei dieser Vorrichtung, die aus der DE-PS 25 53 386 bekannt ist, ist es nachteilig, daß bei der Beschickung des Kühlschachtes mit dem glühenden Koks eine Kornentmischung stattfindet, die zu einer nachteiligen ungleichmäßigen Durchgasung des Koksbettes im Kühlschacht führt. Bei dieser Vorrichtung ist es außerdem nachteilig, daß der heb- und senkbare Trichter zusätzlich seitlich manipulierbar ausgestaltet ist und zusammen mit dem Kühlschachtverschluß auf einem gemeinsamen Fahrgestell angeordnet ist, wodurch vergleichsweise viel Platz benötigt wird. Insbesondere ist es bei dieser Beschickeinrichtung nachteilig, daß beim Abheben des Kühlschachtverschlusses und seitlichen Verschieben des auf- und abbewegbaren Trichters Staubemissionen seitlich am stationären Trichter vorbei in die Atmosphäre entweichen können, bis der Trichterverschluß seine Abdichtstellung eingenommen hat.In this device, which is known from DE-PS 25 53 386, it is disadvantageous that grain separation takes place when charging the cooling shaft with the glowing coke, which leads to a disadvantageous uneven gasification of the coke bed in the cooling shaft. In this device, it is also disadvantageous that the lifting and lowering funnel is designed to be laterally manipulable and is arranged together with the cooling shaft closure on a common chassis, whereby a comparatively large amount of space is required. In particular, it is disadvantageous in this loading device that when the cooling shaft closure is lifted and the funnel that can be moved up and down is laterally moved, dust emissions can escape laterally past the stationary funnel into the atmosphere until the funnel closure has assumed its sealing position.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden und die gattungsgemäße Kokseintragsvorrichtung zu vereinfachen, gleichzeitig den Verschlußvorgang für den beweglichen Trichter zu verkürzen, die Durchgasung des Koksbettes zu verbessern und die Staubemissionen wesentlich zu verringern.The invention has for its object to avoid these disadvantages and to simplify the generic coke entry device, at the same time to shorten the closing process for the movable funnel, to improve the gas flow through the coke bed and to significantly reduce the dust emissions.

Die Lösung dieser Aufgabe wird bei einer gattungsgemäßen Kokseintragsvorrichtung durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved in a generic coke entry device by the characterizing features of claim 1.

Vorteilhafte Weiterbildungen sind in den Unteransprüchen aufgeführt.Advantageous further developments are listed in the subclaims.

Die im Trichter der erfindungsgemäßen Kokseintragsvorrichtung angeordnete Verteilerglocke vermeidet beim Einfüllen des glühenden Kokses Entmischungserscheinungen im Kühlschacht. Beim Einfüllen ohne Verteilerglocke treten nämlich Entmischungen im Koksbett des Kühlschachtes auf, die die Durchgasung behindern.The distributor bell arranged in the hopper of the coke input device according to the invention avoids separation phenomena in the cooling shaft when the glowing coke is filled. When filling without a distributor bell, segregation occurs in the coke bed of the cooling shaft, which hinders the gas flow.

Außerdem entfällt bei der erfindungsgemäßen Kokseintragsvorrichtung, ausgenommen die Variante, bei der nach dem trockenen Metall zu Metall-Dichtungsprinzip ein praktisch emissionsfreies seitliches Verschieben möglich ist, die seitliche Ausweichbewegung des auf- und abbewegbaren Trichterunterteils. Dadurch wird der konstruktive Aufwand verringert. Zugleich werden die Staubemissionen wesentlich vermindert, weil das auf- und abbewegbare Trichterunterteil nur einen vergleichsweise geringen Spalt freiläßt. Im übrigen wirkt der Trichter infolge der Saugwirkung des Gebläses wie ein Rauchfang, so daß die seitliche Falschluftansaugung Staubemissionen praktisch vollständig verhindert.In addition, with the coke input device according to the invention, with the exception of the variant in which a practically emission-free lateral displacement is possible according to the dry metal-to-metal sealing principle, the lateral evasive movement of the funnel lower part which can be moved up and down is eliminated. This reduces the design effort. At the same time, dust emissions are significantly reduced because the bottom part of the funnel, which can be moved up and down, leaves only a comparatively small gap. In addition, the funnel acts as a chimney fan due to the suction effect of the blower, so that the lateral intake of false air practically completely prevents dust emissions.

In Figur 1 ist ein stationärer Trichter 1 abgebildet, der in einer Stützkonstruktion 7 verlagert ist und dem ein heb- und senkbarer Dichtring 11 zugeordnet ist, der gleichzeitig als heb- und senkbares Trichterunterteil 18 ausgestaltet ist und über eine Antriebseinheit 16 betätigbar ist. Diese dient zugleich zum Heben und Senken einer Verteilerglocke 5, die an einen Querträger 39 über ein Rohrstück 40 angeschlossen ist, wie aus Figur 2 ersichtlich ist. Die Stützkonstruktionen 7 sowie die Antriebseinheit 16 sind auf einer Bühne 42 abgestützt und befestigt, die in Höhe des Schachtkopfes 51 an einen Kühlschacht 41 angeordnet ist.1 shows a stationary funnel 1, which is displaced in a support structure 7 and to which a lifting and lowering sealing ring 11 is assigned, which is at the same time designed as a lifting and lowering funnel lower part 18 and can be actuated by a drive unit 16. This also serves to raise and lower a distributor bell 5, which is connected to a cross member 39 via a pipe section 40, as can be seen from FIG. The support structures 7 and the drive unit 16 are supported and fastened on a platform 42, which is arranged at the level of the shaft head 51 on a cooling shaft 41.

Auf dem Schachtkopf 51 des Kühlschachtes 41 ist eine Wassertasse 10 vorgesehen, in die der Dichtring 11 in Dichtstellung hineinragt (Figur 2). Am stationären Trichter 1 sind Absaugleitungen 9 angeordnet (Figur 2), an die hier nicht dargestellte Sauggebläse angeschlossen sind, die beim chargenweisen Einfüllen des heißen Kokses in den Kühlschacht 41 betrieben werden, sowie in den Umrüstzeiten, in denen nach dem Anheben von Verteilerglocke 5 und Dichtring 11 bzw. Trichterunterteil 18 ein Kühlschachtverschluß 8 aus der Ruhestellung (Figur 4) über ein Fahrgestänge 72 mittels Rollen bzw. Rädern 68 in die Abdichtstellung über dem Kühlschacht 41 (Figur 3) verbracht wird. Einsetzen, Abheben und Verfahren des Kühlschachtverschlusses 8 werden mittels eines Manipulators 14 vorgenommen, der auf der Bühne 42 angeordnet ist. In Dichtstellung des Kühlschachtverschlusses 8 ist ein daran befestigter Dichtring 55 in die Wassertasse 10 abgesenkt (Figur 3).A water cup 10 is provided on the shaft head 51 of the cooling shaft 41, into which the sealing ring 11 projects in the sealing position (FIG. 2). Suction lines 9 are arranged on the stationary funnel 1 (FIG. 2), to which suction fans (not shown here) are connected, which are operated when the hot coke is poured into the cooling shaft 41 in batches, and in the changeover times in which after the distributor bell 5 and Sealing ring 11 or funnel lower part 18, a cooling shaft closure 8 is brought from the rest position (FIG. 4) via a driving linkage 72 by means of rollers or wheels 68 into the sealing position above the cooling shaft 41 (FIG. 3). The cooling shaft closure 8 is inserted, lifted off and moved by means of a manipulator 14 which is arranged on the stage 42. In the sealing position of the cooling shaft closure 8, a sealing ring 55 attached to it is lowered into the water cup 10 (FIG. 3).

In Figur 5 ist die mit Wasser 13 gefüllte Wassertasse 10 dargestellt, in die der Dichtring 11 eingetaucht ist. Die Verbindung mit dem Trichter 1 bildet ein flexibles Abdichtelement 12, daß sich gegen einen Ringkragen 52 des Trichters 1 abstützt.FIG. 5 shows the water cup 10 filled with water 13, into which the sealing ring 11 is immersed. The connection with the funnel 1 forms a flexible sealing element 12 that is supported against an annular collar 52 of the funnel 1.

In Figur 6 ist die Antriebseinheit 16 zum Heben und Senken der Verteilerglocke 5 und des Dichtringes 11 im Detail dargestellt, die im Beispiel als Linearantrieb ausgebildet ist.FIG. 6 shows the drive unit 16 for lifting and lowering the distributor bell 5 and the sealing ring 11 in detail, which in the example is designed as a linear drive.

In den Figuren 7 bis 10 ist eine andere Ausgestaltung des heb- und senkbaren Trichterunterteils 18 dargestellt, das dem auf dem Stützgerüst 7 verlagerten stationären Trichter 1 zugeordnet ist und zugleich die Funktion eines Dichtrings 111 mit wahrnimmt. Die Verteilerglocke 5 ist über das Rohrstück 40 und den Querträger 39 fest am Trichterunterteil 18 angebracht. In angehobener Stellung (Figur 9) ist ausreichend Platz vorhanden, um den Kühlschachtverschluß 8 aus seiner Ruhestellung (Figur 10) über den Schachtkopf 51 des Kühlschachtes 41 zu manipulieren und dort in seine Dichtstellung abzusenken. Die Antriebseinheit 19 für das heb- und senkbare Trichterunterteil 18 ist im Beispiel als Doppel- Schubkolbengetriebe ausgestaltet, deren Kolben 71 an einer Traverse 17 angeschlagen sind, an dem das Trichterunterteil 18 befestigt ist. Die Antriebseinheit 19 ist gegen Widerlager 70 abgestützt (Figur 8).FIGS. 7 to 10 show another design of the lower and lowerable funnel part 18, which is assigned to the stationary funnel 1 displaced on the supporting frame 7 and at the same time also performs the function of a sealing ring 111. The distributor bell 5 is fixedly attached to the lower part 18 of the funnel via the pipe section 40 and the cross member 39. In the raised position (FIG. 9) there is sufficient space to manipulate the cooling shaft closure 8 from its rest position (FIG. 10) via the shaft head 51 of the cooling shaft 41 and to lower it there into its sealing position. In the example, the drive unit 19 for the lower part 18 of the funnel which can be raised and lowered is designed as a double thrust piston transmission, the pistons 71 of which are attached to a crossmember 17 to which the lower part 18 of the funnel is fastened. The drive unit 19 is supported against abutment 70 (Figure 8).

In Figur 11 ist als Detail eine Wassertasse 10 abgebildet, in deren Wasserfüllung 13 der fest am Trichterunterteil 18 angebrachte Dichtring 111 in Dichtstellung eingelassen ist.A water cup 10 is shown as a detail in FIG. 11, in the water filling 13 of which the sealing ring 111 fixedly attached to the lower funnel part 18 is inserted in the sealing position.

In den Figuren 12 bis 15 ist eine Ausgestaltung der Kokseintragsvorrichtung dargestellt, die sich von der des Gegenstandes der Figuren 7 bis 10 durch eine im Überlappungsbereich des stationären Trichters 1 mit dem Trichterunterteil 18 vorgesehene Anordnung der Absaugleitung 9 unterscheidet, die konstruktive Anpassungen am stationären Trichter 1 und am Trichterunterteil 18 bedingen, die deren äußere Formgestaltung betreffen, wie den Figuren 12 bis 15 im einzelnen entnehmbar ist.FIGS. 12 to 15 show an embodiment of the coke entry device which differs from that of the object of FIGS. 7 to 10 by an arrangement of the suction line 9 provided in the area of overlap of the stationary funnel 1 with the lower funnel part 18, the structural adaptations to the stationary funnel 1 and condition on the lower part 18 of the funnel, which relate to their external shape, as can be seen in detail in FIGS. 12 to 15.

In den Figuren 16 bis 18 ist eine Ausgestaltung der Kokseintragsvorrichtung dargestellt mit einer heb- und senkbaren Verteilerglocke 5, die an einer Traverse 17 befestigt ist, die auf- und abbeweglich in Führungsöffnungen 67 des stationären Trichters 1 geführt ist, die durch Abdichtbleche 34 verschließbar sind, die mit der Traverse 17 verbunden sind. Das Anheben und Absenken erfolgt durch Antriebseinheiten 190, die an den Enden der Traverse 17 angeschlagen sind (Figur 17).16 to 18 show an embodiment of the coke entry device with a liftable and lowerable distributor bell 5, which is attached to a crossmember 17, which is guided up and down in guide openings 67 of the stationary funnel 1, which can be closed by sealing plates 34 , which are connected to the traverse 17. The lifting and lowering is carried out by drive units 190, which are attached to the ends of the crossmember 17 (FIG. 17).

Dem stationären Trichter 1 ist ein um ein geringes Hubmaß heb- und senkbares Trichterunterteil 18 zugeordnet. Außerdem verfügt diese Kokseintragsvorrichtung über einen verschiebbaren Trichter 202 und einen verschiebbaren Kühlschachtverschluß 800. Der verschiebbare Trichter 202 und der verschiebbare Kühlschachtverschluß 800 werden über einen gemeinsamen Antrieb verschoben. Der Antrieb ist in der Zeichnung nicht abgebildet.The stationary funnel 1 is assigned a funnel lower part 18 which can be raised and lowered by a small stroke. In addition, this coke entry device has a displaceable funnel 202 and a displaceable cooling shaft closure 800. The displaceable funnel 202 and the displaceable cooling shaft closure 800 are displaced via a common drive. The drive is not shown in the drawing.

In Figur 16 ist der verschiebbare Kühlschachtverschluß 800 in Abdichtstellung und der verschiebbare Trichter 202 in Ruhestellung dargestellt. Sowohl der verschiebbare Trichter 202 als auch der verschiebbare Kühlschachtverschluß 800 tragen beidseitig metallische Dichtringe 31, die mit entsprechenden metallischen Dichtringen 31 korrespondieren, die am Schachtkopf 51 bzw. im unteren Bereich des heb- und senkbaren Trichterunterteils 18 angeordnet sind. Die metallischen Dichtringe 31 können auf ihrer Dichtseite wahlweise gepanzert oder weichdichtend ausgebildet sein, gegebenenfalls ist eine Kühlung vorgesehen. Zur Reinhaltung der metallischen Dichtringe 31 sind Düsenringleitungen 32 vorgesehen, die mit Druckluft beaufschlagt werden. In Ruhestellung können der verschiebbare Trichter 202 bzw. der verschiebbare Kühlschachtverschluß 800 in Abdeckplatten 35 geführt und federnd verlagert sein. Durch die Anwendung des trockenen Metall zu Metall-Dichtungsprinzips werden bei den Austauschvorgängen des verschiebbaren Trichters 202 gegen den verschiebbaren Kühlschachtverschluß 800 praktisch keine Öffnungen zur Atmosphäre hin frei, durch die in diesem Bereich Staubemissionen entweichen könnten.FIG. 16 shows the sliding cooling shaft closure 800 in the sealing position and the sliding funnel 202 in the rest position. Both the displaceable funnel 202 and the displaceable cooling shaft closure 800 carry on both sides metallic sealing rings 31 which correspond to corresponding metallic sealing rings 31 which are arranged on the shaft head 51 or in the lower region of the lower and lowerable funnel part 18. The metallic sealing rings 31 can be either armored or soft-sealing on their sealing side; cooling is optionally provided. To keep the metallic sealing rings 31 clean, there are nozzle ring lines 32 provided that are supplied with compressed air. In the rest position, the displaceable funnel 202 or the displaceable cooling shaft closure 800 can be guided in cover plates 35 and displaced in a resilient manner. Due to the use of the dry metal to metal sealing principle, practically no openings to the atmosphere through which dust emissions could escape in this area are free during the exchanges of the displaceable funnel 202 for the displaceable cooling shaft closure 800.

Wie aus Figur 18, einer Detaildarstellung, zu entnehmen ist, ist das heb- und senkbare Trichterunterteil 18 im Beispiel zweiteilig ausgestaltet und setzt sich aus einem Anpreßring 330 und aus einem Teleskopring 333 zusammen. Der Anpreßring 330 ist unten mit einem metallischen Dichtring 31 ausgerüstet und oben mit einer Auskragung 331, der ein Antrieb 332 zugeordnet ist, im Beispiel ein Schubkolbengetriebe, dessen Kolben 335 den Anpreßring 330 an den metallischen Dichtring 31 des verschiebbaren Kühlschachtverschlusses 800 bzw. des verschiebbaren Trichters 202 anpreßt. Der Teleskopring 333 ist in dem Anpreßring 330 geführt und weist einen Kompensator 334 auf.As can be seen from FIG. 18, a detailed illustration, the lower and lowerable funnel part 18 is configured in two parts in the example and is composed of a pressure ring 330 and a telescopic ring 333. The pressure ring 330 is equipped at the bottom with a metallic sealing ring 31 and at the top with a projection 331, to which a drive 332 is assigned, in the example a thrust piston gear mechanism, the piston 335 of which presses the pressure ring 330 onto the metallic sealing ring 31 of the displaceable cooling shaft closure 800 or the displaceable funnel 202 presses. The telescopic ring 333 is guided in the pressure ring 330 and has a compensator 334.

Wie in den Figuren 19, 20 und 21 beispielhaft dargestellt ist, kann der stationäre Trichter 1 der Kokseintragsvorrichtung mit einem Trichterverschluß 20 ausgerüstet sein, der aus zwei Verschlußplatten 64 und 65 besteht, die in Figur 19 in Öffnungsstellung und in Figur 20 in Schließstellung abgebildet sind. In der raumbildlichen Darstellung der Figur 21 ist die Verschlußplatte 64 an einem Hebelgestänge 66 befestigt, das über einen Antrieb 21 betätigbar ist.As shown by way of example in FIGS. 19, 20 and 21, the stationary hopper 1 of the coke entry device can be equipped with a hopper closure 20 which consists of two closure plates 64 and 65, which are shown in FIG. 19 in the open position and in FIG. 20 in the closed position . In the spatial representation of FIG. 21, the closure plate 64 is fastened to a lever linkage 66 which can be actuated via a drive 21.
