| 摘要 |
A feed and dewatering device for dewatering and squeezing material in form of sludge, sediment, suspensions, peat, etc., comprises two co-operating sections (1; 2), each comprising a feed screw (19, 20; 21, 22) and a seave mantle (4; 15) surrounding the feed screw. The first section (1) in the feed direction is formed for dewatering mainly by self-drainage. The section has a rotating seave mantle (4) and is provided with means (33) for cleaning the seave mantle holes (5). The second section (2) is formed for increased compression of the material, wherein the thread height for the feed screw (21, 22) is less at the outlet (24) of the section (2) than at the inlet to this section. |
