ABSTRACT:
The apparatus comprises a housing, a filtering device, mechanisms for driving the filtering device, respectively, through rotation and reciprocation and a device for discharging impurities from the filtering device. The filtering device includes the top and bottom plates spaced from one another, the top plate being mounted on a hollow stem, and the bottom plate being mounted on another stem extending through the hollow one. In accordance with the invention, to adjust the spacing of the plates, the filtering device includes a resilient member supported by the stem extending through the hollow one and adapted to cooperate with the hollow stem so as to maintain the relative position of the plates. The end of the same stem extending through the hollow stem, remote from the bottom plate, carries a first abutment cooperating with the resilient member. The end of the hollow stem carries an adjustable abutment adjoining the first abutment, the relative position of the adjustable abutment and the first abutment defining the desired spacing of the plates.
