A device for dewatering and/or transport of liquid-containing screening or sludge material. The device includes a chamber (10) which is being under a reduced pressure and which is formed by the walls (11-13), with an inlet (14) and with means (24, 25) for continuously compression and separation of liquid from the screening material/the sludge. Which means act toward an outlet opening (15, 31), for evacuation of incoming material without equalization of air pressure. The inlet (14) includes a pipeline (17) with a valve (18) which can be opened and closed for recurrent intake of a quantity of screening material in the pipeline and for a direct or gradual transport of said quantity along the pipeline (17) and into the chamber (10), under preservation of a varying pressure in the chamber (10). |
