Device for lifting and removing oven doors of a cooking oven
View Patent ↗The invention relates to a device for lilting and removing oven doors of a coking oven that is comprised of a door removing head ( 1 ), which can be coupled to vertically extending oven doors of a horizontal chamber coking oven, of a drive device ( 3 ) for effecting adjusting movements of the door removing head ( 1 ), and of a suction hood, which can be displaced along the horizontal chamber coking oven above the oven door. According to the invention, sealing elements ( 5 ) are connected to the door removing head ( 1 ) and, on both sides of an oven door ( 2 ) to be opened, can be displaced against front contact surfaces ( 6 ) of the horizontal chamber coking oven. Said sealing elements extend essentially over the entire height of the oven door ( 2 ) and into the suction area ( 4 ) of the suction hood, and they form a suction chamber ( 8 ) for door emissions when the oven door ( 2 ) is opened.
1. A device for lifting and removing oven doors of a coking oven comprising
a door removing head ( 1 ) which can be coupled to vertically extending oven doors of a horizontal chamber oven;
a driving device ( 3 ) for setting movements of the door removing head ( 1 ); and
a suction hood which can be displaced above the oven doors along the horizontal chamber oven;
characterized in that sealing elements ( 5 ) are connected to the door removing head ( 1 ), said sealing elements being movable on both sides of an oven door ( 2 ) to be opened against front-side contact surfaces ( 6 ) of the horizontal chamber oven, and extending substantially over the entire height of the oven door ( 2 ( ) up into the suction area ( 4 ) of the suction hood, and forming a suction chamber ( 8 ) for door emissions when the oven door ( 2 ) is opened.
2. The device according to claim 1 , characterized in that the door removing head ( 1 ) comprises mechanical electromechanical, pneumatic or hydraulic setting devices controlling the setting movements of the sealing elements ( 5 ) in such a manner that the sealing elements ( 5 ) come to rest against the front-side contact surfaces ( 6 ) of the horizontal chamber oven as a lifting and removing movement of the oven door ( 2 ) coupled to the door removing head ( 1 ) is taking place.
3. The device according to claim 1 or 2 , characterized in that the sealing elements ( 5 ) are designed in the form of pivot-mounted wings.
4. The device according to claim 1 or 2 , characterized in that the sealing elements ( 5 ) are designed in the form of sliding walls movable from a recessed position by a straight setting movement against the front-side contact surfaces ( 6 ) of the horizontal chamber oven.
5. The device according to any one of claims 1 to 4 , characterized in that the sealing elements ( 5 ) can be moved between a resting position (II) and a working position (III), whereby the sealing elements ( 5 ) are pushed or swiveled back in the resting position (II) to an extent such that the coupling operation taking place between the door removing head ( 1 ) and the closed oven door ( 2 ) can be observed.
6. The device according to any one of claims 1 to 5 , characterized in that the suction hood has a length not substantially exceeding the width of the oven chamber of the horizontal chamber oven.
