Abstract: A method for filtering and backwashing solid particles out of liquids is illustrated, with a filter drum (5) positioned completely below the liquid level (6) having a cylindrical surface (7) coated with a filter medium (8), the liquid flown through the outside of the filter drum to the inside. A backwashing device for removal of the filter cake from the filter medium is provided. At the beginning of each cycle of backwashing an air cushion (15) is introduced in the filter drum (5) and liquid in the filter drum (5) is displaced in such a manner so that liquid jets from an ejetion apparatus (19) containing a spraying head (17) and being arranged in the interior of the filter drum without being sealed on the filter drum penetrate through the air cushion (15) to the backside of the cylindrical surface (7) of the filter drum (5). The filter cake so removed from the filter drum is withrawn at the outside of filter drum (5) in a stream of liquid.

Abstract: Liquid filter devices, particularly for irrigation systems are known to comprise automatic, periodic reverse-flow rinsing arrangements, whereby water is flushed in the opposite direction to release clogged particles from the filter member. The disclosed devices utilize the reverse, flushing water flow to release the filter member of the device from its normal, stationary position, and rinse it by jets. The jets are also useful to impart a rotatable movement to the filter member. In the case of disc filters, the discs become released and spaced from each other, and individually spin during the rinsing thereof.

Abstract: An apparatus having a bowl-shaped screen with a large opening at the upper end thereof and a smaller opening at the lower end thereof for screening annularly distributed influent. An influent manifold is located above the screen to distribute influent downwardly into the upper opening. An effluent receiver is positioned about the screen while a concentrate receiver is positioned below the lower opening of the screen. A distributor cone is positioned in the upper opening to direct influent outwardly and downwardly to the screen. The cone is vertically adjustable to vary the size of the annular opening between the cone and the screen. The cone is also rotatably mounted to aid in uniformity of distribution. A tangential influent feed is employed to induce rotation of the distribution cone. A rotatably mounted backspray manifold extends about the screen with nozzles directed to induce rotation of the manifold. A wiper blade extending to the lower opening of the screen is attached to the backspray manifold for inducing concentrate into the concentrate receiver.

Abstract: A filter apparatus comprises a filter element inside a stationary housing. In one embodiment, an inlet manifold extends helically along the outside of the housing. A director blade within the housing causes the unfiltered liquid from the inlet manifold to strike the filter element tangentially in a direction opposing filter element rotation. The filtered liquid passing through the filter element is withdrawn from the interior of the filter element. A stationary vane or deflector inside the filter element parallels the director blade and inlet manifold and forces some filtered liquid radially outwardly through the filter element, at the point where the inward flow impinges on the filter element, for loosening contaminant from the outside of the filter element. Adjacent this point a gathering blade extends inward from the housing toward the filter element in parallelism with the inlet manifold to intercept the rotational flow and loosened contaminant adjacent the outside of the filter element and direct same radially outwardly into a drain chamber, creating a vortex flow therein. The drain chamber is oriented and contoured to cause vortex flow downwardly to direct contaminant particles to a drain. In another embodiment, the helical inlet manifold is omitted and the filter liquid is merely introduced into the housing externally of the filter element by a suitable conduit. In a further embodiment, the guide vane or deflector inside the filter element is omitted and a backwash liquid supply tube is provided within the filter element opposite the gathering blade and has outlet openings facing the filter element wall for direction of backwash liquid flow outwardly through the filter element to force contaminant particles from the exterior of the filter element.

Abstract: 387,339. Filters. BURRELL, B. S., 3502, Fir Street; East Chicago, U.S.A. July 22, 1931, No. 20963. Convention date; June 23, 1930. [Class 46.] A rotary strainer drum comprises two cylindrical shells with coincident apertures and an intermediate straining medium, the apertures in the shell through which the fluid passes first being such as to form pockets for the retention of the solid matter. A straining element, comprising wire gauze held between perforated cylinders 28, 29, Figs. 1 and 2, fits closely in a stationary liner 13 in a casing 9 with its ends in annular bearing sockets sand is rotated by means of a shaft 36. Liquid or gas from an inlet 10 passes through Openings 14 in the liner, and the wall of the straining element and is delivered axially through an outlet 21. A member 37, which is pivoted to rest against a longitudinal section of the element opposite to the inlet 10, directs a portion of the strained fluid through a tapering slot 43 and outward through this section of the element so that impurities, carried round from the inlet 10 in the pockets formed by the apertures in the outer cylinder, are fluahed away through a slot 15 of the liner 13 to a waste outlet 17. In a modification shown in Figs. 4 and 5 the interior of the strainer is divided into compartments by a partition 74. The fluid enters axially and strained fluitl passes away through an outlet 67. A portion of the strained fluid is led back through a passage 90 and directed by a slot 91 in the liner 65 inwardly through a section of the strainer to the compartment behind the partition 74, flushing impurities away through a waste outlet 93. The Specification as open to inspection under Sect. 91 comprises also apparatus shown in Fig. 4 (Cancelled) in which the wire gauze is not protected by an inner perforated cylinder. The fluid enters through a pipe 50 and the main ,part is directed by a partition 59 to pass outwardly through the strainer to an outlet 47. A part, however, passes through apertures 60 and flushes solid matter from that part of the strainer, separated from the outlet 47 by the partition 59, away through a waste outlet 62. This subject-matter does not appear in the Specification as accepted.
