Abstract
A continuous filtration/separation apparatus with a part of the casing of a vane pump constructed of a filter so that material to be treated which is introduced between the casing and the vane adjacent to the rotor can be dehydrated. The endless filter of the vane pump at one portion faces the rotor of the casing and moves successively. The vane pump also has a washing device for washing the other portion of the endless filter which does not face the rotor, to eliminate clogging of the filter. A support supports an arc portion facing the rotor of the casing, which arc portion is rotatable about a center which is eccentric relative to the center of rotation of the rotor, so that the dehydrating ratio can be adjusted. A drive rotates the arc portion about its center for adjustment of the dehydration ratio.
