Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To take flocculated flocs out of a thickening vessel without destroying the flocs by scooping up the flocculated sludge flocs in water, placing the scooped up sludge flocs on a screen and draining moisture by utilizing its own weight and the compact by eccentricity. SOLUTION: The drum screen 2 spread with the screen in its circumference part is freely rotatably and eccentrically in the semi-cylindrical thickening vessel 1 so as to narrow the side where a scooping-up plate 11 emerges from the inside of the water. Both ends of the scooping-up plate 11 are freely fitted into slits 2b respectively formed in the radial direction of the right and left side plates 2a of the drum screen 2 to make the scooping-up plate 11 movable radially within the slits 2b so that the scooping-up plate 11 moves into and out of the screen plane of the drum screen 2 according to the rotation of the drum screen 2. As a result, the scooping-up plate 11 projects from the outer periphery of the drum screen 2 and scoops and lifts the flocculated flocs, thereby putting the flocs on the screen.  Further, the compaction is applied on the floes and the flocs are transported while the moisture is drain. The flocs are thus gathered through the scraper 12 to a concd. sludge vessel 13.

Filed: 1993-07-20
Abstract: PURPOSE:To develop the crank shaft having excellent machinability and fatigue strength and excellent wear resistance as well by subjecting the crank shaft consisting of a non-tempered steel as a blank to hardening and tempering under specific conditions, then subjecting the crank shaft to surface plasticity working. CONSTITUTION:The non-tempered steel contg. carbon at a relatively low ratio of 0.30 to 0.40% C is used as the blank of the crank shaft 10 and is molded to an approximate shape of the crank shaft by forging and heat treatment and thereafter, the molded steel is subjected to rough lathing and grinding stags and is thereby molded to the crank shaft 10. The content of the C is relatively low and, therefore, the crank shaft which is easy to machine and has the excellent fatigue strength is obtd. The crank shaft is subjected to the high-frequency hardening and tempering to suppress the hardness Hv to about 400 to 500 and to prevent the generation of quenching rack. The surfaces of journal parts 12 and pin parts 14 are then subjected to surface plasticity working, such as shot peening, by which these parts are hardened to 500 to 700 Hv surface hardness. The crank shaft having the improved wear resistance is thus produced.
