The present invention relates to a device for the separation of a liquid from a sludge (12) or a liquid containing particles by means of a rotatable drum (1), inside which an inlet device for the supply of a sludge (12) or of a liquid containing particles debouches, the jacket (3) of said drum exhibiting ports (2) for making said separation of liquid possible, the drum (1) in its interior exhibiting a screw-type flange element (11) for the forward feed of the sludge, which flange (11) follows the rotating movement of the drum, said flange (11) extending from the inside of the jacket (3A) of the drum in direction towards the center (13) of the same. The invention makes possible an effective supply of sludge (12) etc. to the interior of the drum and an effective separation of liquid from said sludge (12). The inlet device (28) with a number of outlet openings (30, 31) extends unto and along said rotatable jacket (3) of the drum, and portion of the screw (11) for forward feed exhibits an increasing height of the flange blade (a, b, c etc.) along a substantial extension of the drum (1) as counted in the direction of forward feed, i.e. the distance occupied by the flange (11a, 11b, 11c etc.) in direction away from the jacket (3) of the drum towards the center of the drum (1) increases, whereby material accumulated between the flange sections can be received in an increasing quantity in the direction of the forward feed. |
