Abstract: 118,855. Bontemps, A., and Vis, G. N. March 16, 1917. Strainers having sheet straining-materials.-In apparatus for continuously separating solids from liquids, and of the kind wherein the mixture is forced upwards through a pipe 1 into a, chamber 2 having perforated walls 7, and a rotating screw 3 in the chamber continuously removes the solids, the screw comprises a hollow cone 4 placed vertically with its apex at the bottom, and the outlet 13 by which the solids leave the chamber 2 is adjustable. In the construction shown in Figs. 1 and 2, the filtrate escapes by a pipe 12, and the solids by an outlet 17 formed in the bottom of an annular trough 14, in which travels a scraper 15 attached to the rotating cone. The cone is rotated by bevelgearing from a shaft 37. The outlet 13 is adjustable by means of a screw-threaded collar 18 provided with a detachable handle 19. The solid residue may be washed or treated with liquid or steam admitted by cocks 22, 26, 24, 27 to conduits 20, 21 inside the cone, from which they issue by outlets 23, 23', 28. A flue 34 enables steam and gases to escape. In the construction shown in Fig. 5, the solids leave the filtering-chamber by an outlet Y and fall through the hollow cone V to a conveyer W. The outlet Y can be adjusted while the apparatus is running, by means of a sliding ring L actuated by a hand-screw Z. A scraper N is secured to the ring L. The cone is rotated by worm gearing c, d. Washing fluids admitted by cock 0, P issue from the cone by outlets a, and those admitted by cocks Q, R pass twice through the straining-medium and leave by a pipe S. According to a further modification, the outlet from the straining-chamber is adjusted by a sliding collar situated, like the collar 18, Fig. 1, on the rotating cone and adjusted by a hand-screw in the same way as the ring L, Fig. 5.
