ABSTRACT:
A hollow upright shaft is surrounded at axially spaced locations by spacer rings. Intermediate these rings the shaft is surrounded by substantially horizontally oriented plate-shaped filter elements which rotate with the shaft. Each filter element has a liquid-impermeable annular plate the upper surface of which carries a filter material. The inner circumference of the plate is formed with a downwardly extending stepped collar which is received in the subjacent spacer ring and thus centers the filter element with reference to the ring and to the shaft. The latter has openings in its periphery through which filtered liquid can flow into the interior of the shaft, to be led away.
