Abstract

1345180 Filter A H PARMENTIER 19 April 1971 [14 April 1970 11 Aug 1970 31 March 1971] 27331/71 Heading B1D A filter comprises a tank 1 enclosing rows of flat-sided, rectangular, vertically oriented, inward flow filter elements 7, mounted directly on and extending parallel to respective filtrate outlet pipes 4, and a framework 17, 18, 19 reciprocable by double-acting jack 30 and carrying means 21 which cleans the large surfaces of elements 7. As shown the framework moves horizontally and means 21 are vertical scraper blades, but the blades could be horizontal and the movement vertical, and the blades could be replaced or supplemented by pairs of nozzles (33) (Figs. 4, 5, not shown) which direct jets of wash liquid across the elements. The lower edges of elements are clamped to pipes 4 by upper beams 13 and bolts 12, and their large surfaces are covered by filter cloth or metal screen. The elements and pipes 4 have aligned apertures. Pipes 4 are connected at one or both ends to filtrate collectors 16 leading to a suction pump, or the filter may operate by gravity flow. In one mode of operation, the apparatus acts as a continuous thickening filter, the level in tank 1 is maintained by a float-controlled inlet valve, the framework is moved intermittently in alternate directions, and solids scraped from the elements are removed through outlet valve 32. Alternatively, the tank 1 is periodically drained through valve 32 and the elements cleaned by reciprocation the scrapers and/or wash nozzles. In the latter case, a valve may be provided whereby first and second filtrates are collected separately. The jack and valves could be pneumatically actuated under the control of electric switches operated by respective cams rotated by a timer motor. Blades 21 may be rigid or resilient and may be spaced from the surfaces of elements 7. The framework is guided by bars 25, 29 and runs on wheels 24 in Fig. 3.
