ABSTRACT:
An extraction device for treating liquid-solid mixtures such as sewage sludge or paper pulp to remove liquid therefrom, includes a preliminary treatment station. The preliminary treatment station comprises at least two interchangeable perforated containers located on a displaceable receiver turntable beneath which a stationary disc is coaxially located. The stationary disc is provided with an aperture eccentrically disposed thereon, the aperture having a cross-sectional area corresponding to the cross-sectional area of the lower end of the container located on the turntable and to the cross-sectional area of an inlet aperture provided in the extraction device.
By rotating the receiver turntable in a timed sequence a container is always moved beneath a filler tube, filled and further rotated. The solid components drop to the bottom of the container and liquid is discharged through the perforations provided in the container and the mixture thus has liquid removed in a preliminary treatment. The solid-containing mixture is finally passed over then fed into a conventional extraction device. In a subsequent cycle, the next perforated container is filled, and a preceding container is emptied by being displaced until it is located above the filler aperture of the extraction device.
