The servicing apparatus (2) useful in a biogas plant (1), comprises a servicing unit, a servicing area, and a movable sealing device provided in the servicing unit, where the biogas plant comprises a fermenter container (4) and has a fermentation zone (5) and a gas zone (6) on an inner chamber of the fermenter container. The fermenter container is gas-tightly connected by a gas sealing wall arranged onto the fermenter container. The sealing device is movable between a rest position and a sealing position in the intended assembly and is used to gas-tightly separate the servicing area. The servicing apparatus (2) useful in a biogas plant (1), comprises a servicing unit, a servicing area, and a movable sealing device provided in the servicing unit, where the biogas plant comprises a fermenter container (4) and has a fermentation zone (5) and a gas zone (6) on an inner chamber of the fermenter container. The fermenter container is gas-tightly connected by a gas sealing wall arranged onto the fermenter container. The sealing device is movable between a rest position and a sealing position in the intended assembly and is used to gas-tightly separate the servicing area from the gas zone in the sealing position. The servicing area is connected with the gas zone in the rest position in a gas-permeable manner. The servicing unit comprises a connection frame and the sealing device is fixed onto the connection frame. The connection frame is fixed at a supporting console of the servicing unit. The sealing device comprises a sealing wall made of flexible material. The sealing device in the sealing position is longer than in the rest position. The sealing device has bellows, and is prolonged in a telescope-like manner. The servicing apparatus includes an adjustable guiding element such as a guiding rope or a guiding chain, with which the sealing device is adjustable, where the sealing wall of the sealing device is lowered from the rest position to the sealing position with the guiding element. Several clamping frames are provided at the sealing device and clamp off the sealing wall at several positions spaced to each other. A weighting device connects with the lower end of the sealing device to transfer the sealing device from the rest position to the sealing position during releasing the guiding element. A crank drive is connected with the guiding element. The sealing device is arranged in the servicing apparatus in the rest position. An independent claim is included for a biogas plant. |
