The sealing device is for drum filters or filter presses to form a seal between the rotary drum end faces and the end faces of the trough in which the rotary drums are situated. A sealing element ( 3 ) is disposed in a groove ( 1 ) on the rotary drum end face, in which the sealing element ( 3 ) is pressed into contact against the opposite part by a hose element ( 2 ), preferably in form of two flexible hoses ( 2 a , 2 b), which can be pressurized internally. The hoses ( 2 a , 2 b) are disposed one on top of the other in the groove ( 1 ) beneath the sealing element ( 3 ). The two open ends of the hose element ( 2 ) are provided with sleeves ( 7 ) which enclose the ends. The sleeves ( 7 ) are held in place in the groove ( 1 ) with a holder element ( 10 ). Spaces ( 19 a , 19 b) are formed on both sides of the middle piece ( 12 ) of the holder element. One space ( 19 a) is provided with an inlet ( 17 ) for pressurizing medium and the other space ( 19 b) is provided with an outlet ( 18 ) for the pressurizing medium. The sealing device also has a sleeve ( 7 ) and a holder element ( 10 ). |
