Abstract (en)

[origin: WO9949951A1] The invention relates to an apparatus for removing filtered material from a pressurised filter space, in which filter space there are installed members for feeding the material to be processed to filtering carried out in a pressurised space, as well as members for removing the product, i.e. the filtered material created in the process, from the pressurised filter space. According to the invention, in the material discharge end of the discharge conduit (3, 21) of the filtering space, there is connected an adjusting member (4, 27), said adjusting member (4, 27) comprising at least two adjusting elements (5, 6; 29, 30) which are provided with ports (7, 33) and are movable in relation to each other, in order to maintain the measurable filtered material surface height (11, 28) in the discharge conduit (3, 21) essentially at a predetermined value in a substantially continuous fashion.
