Abstract

544,200. Filters. STANDARD OIL DEVELOPMENT CO. Dec. 5, 1940, No. 17308. Convention date, Nov. 30, 1939. [Class 46] A sectionalized inward flow rotary drum filter 12 is mounted in a casing 1, Figs. 1 and 2, to the inner wall of which wash-water spray pipes 20 and a scraper 24 for removing the cake are attached and which can be adjusted rotationally. With this arrangement the. period of washing can be increased relatively to that of filtration by supplying liquid to be filtered so that there is a lower liquid, level in the casing and by adjusting the casing clock-wise. In the apparatus shown, the pipes 20 have valved connections with a manifold 21, so that those not required in use can be cut off. The scraper 24 is formed at the edge of a trough 23 provided with a scroll 25 which moves the detached solid to an outlet 11. The casing is supported by arcuate rails 2 which engage rollers 3 on foundation supports 4, and is adjusted by means of a pinion 6, turned by power or by a handle 8 and which engages an arcuate rack 5 on the casing. In the apparatus shown in Fig. 4, the casing is supported by hollow trunnions 31, 32, and adjusted by means of a gear wheel 36 on the trunnion 31. The filter drum is supported by a hollow shaft 35 passing through the trunnions 31, 32 and is divided into sections 34a at right angles to the axis.
