• the side wings are associated with adjusting devices to move the side wings with a separate adjusting movement about the vertical axes against the end faces of the anchor stands.
• the side wings are also subsequently movable against the end faces of the anchor stand, when the tool carrier is already in its working position.
• the basic "sealing position" produced so that the side wings abut the end faces of the anchor stand.
• an insufficient “sealing position” can be subsequently corrected if the side wings do not rest or only incompletely against the end faces of the anchor stands.
• the side wings each have a bent in the direction of the end faces of the anchor stand end, with which they rest against the end faces. Due to the resulting small contact area between the anchor stand and side wing, a higher contact pressure be transferred, so that the seal is improved. Furthermore, for example, coke or dust deposits can be compensated for by unevenness caused at the end faces, since the small contact surface of the bent end bears better than, for example, a broad contact surface of a flat sealing plate.
• a preferred embodiment of the invention provides that the side wings are assigned pressure devices, under the action of the side wings abut the end faces.
• the adjusting or pressure devices bring an additional sealing force, so that there is an improved sealing effect between the side wings and the end faces of the anchor stand.
• the adjusting or pressure devices are elastic springs or hydraulic cylinders. By the spring constants of the springs or by the force of the hydraulic cylinder an improved sealing effect by a precisely matched, specific sealing force can be achieved.
• the center piece is U-shaped, wherein the center piece has a parallel to the furnace chamber aligned central web and associated with this leg.
• the side wings are rotatably mounted at the ends of the legs. With this rotatable mounting, the side wings cover the pivoting range required for the separate positioning movement.
• the U-shaped center piece is located in the area between the anchor stands when the tool carrier is moved forward in its working position for the purpose of cleaning the coke oven chamber frame. In this way, the sealed area in which cleaning emissions occur, further reduced. The space in front of the coke oven chamber is best covered for complete and optimal collection of cleaning emissions.
• the tool carrier can have at least one device for mechanical removal cleaning of the coke oven chamber frame, preferably a scraper. It is understood that other cleaning equipment, such as For example, high-pressure water jet nozzles, can be provided. Basically, those skilled in the art, these cleaning devices are known from the prior art.
• a suction device can be arranged above the tool carrier.
• the suction device covers the sealed area, so the coke oven chamber between the anchor stands before the coke oven door and is tuned with their extraction power to the amount of cleaning emissions arising in this area. Since the resulting cleaning emissions are completely detectable by the device according to the invention, it is possible to avoid the installation of possibly oversized suction capacities.
