摘要： PROBLEM TO BE SOLVED: To provide a screw type filtration dehydrating device capable of directly filtering a low concentration suspension without passing through a concentration process and effectively performing the squeezing out in the later stage, when the liquid content is decreased, to improve the recovery of a suspended material. SOLUTION: A screw conveyer 11 having a core rod 11S tapered to increase the size of the tip is inserted into a center hole 10 of a cylindrical filter body 7 formed by arranging many groups of filter elements each composed of an annular filter plate and an annular movable plate to be laminated. The ratio of the diameter (a) of the core rod 11S in the vicinity of a feed port 8 to that (b) in the vicinity of a discharge port 9 is controlled to 1:1.2-1.5, the ratio of the inside diameter (C) of the annular filter plate to the diameter (a) of the core rod 11S in the vicinity of the feed port 8 is controlled to 1:0.5-0.6 and the ratio of the compressed volume (d) in the vicinity of the feed port 8 to the compressed volume (e) in the vicinity of the discharge port 9 is controlled to 1:0.3-0.5.

摘要： PURPOSE:To provide a suction type recovery method and a device allowing even solid-liquid mixed material with slow fluidity to be recovered easily into a reservoir chamber and to be discharged easily into the atmospheric air from the inside of the reservoir chamber. CONSTITUTION:An upper flow chamber 2a and a lower reservoir chamber 2b communicated vertically, with lip valves 12a, 12b fitted to the respective lower bottom parts are made conductive to a pressure reducing device 1 by separate pressure reducing lines 7, 13 through a relay tank 9. The line resistance of both pressure reducing lines 7, 13 is adjusted to make the vacuum degree in the reservoir chamber 2b larger than that in the flow chamber 2a. This results in increasing the reliability of opening/closing actuation of the upper and lower lip valves 12a, 12b at the time of recovered material flowing down into the reservoir chamber 2b and the reliability of opening actuation of the lower lip valve 12b and closing actuation of the upper tip valve 12a at the time of discharging the recovered material from the inside of the reservoir chamber 2b.

摘要： PURPOSE:To provide a suction type recovery method and a device allowing recovered solid-liquid mixed material to become solid content of a low water content ratio in a recovery tank so as to be discharged, and allowing liquid content to be returned to a supply source for reuse. CONSTITUTION:In suction type recovery technique using a pressure reducing device 1, an upper flow chamber 2a and a lower reservoir chamber 2b with lip valves 12a, 12b fitted to the respective lower bottom parts are provided in the vertically communicated state. Solid-liquid mixed material fed being pumped from a supply source 6 is first recovered into the lower reservoir chamber 2b, and the solid content of the solid-liquid mixed material reaching inside of the upper flow chamber 2a after reaching the saturated state flows down into the reservoir chamber 2b by specific gravity difference. The liquid content of the same volume as the solid content then ascends into the flow chamber 2a from the reservoir chamber 2b, and the solid content of a low water content ratio accumulated in the reservoir chamber 2b is discharged outside. The liquid content in the flow chamber 2a is transferred into a liquid content recovery tank 9.
