    Abstract: In relation to time intervals or pressure loss, the successive flushing via the same flushing channel (10) of several filter elements (7) is brought about by the direct sweeping of the internal surface of said elements (7) by the fluid to be filtered. It comprises a tubular body (1) and an upstream distribution plate (4), each feeding a filter element (7) extending axially inside the body, and a downstream aperture. At its downstream end there is a distributor comprising several inlets linked to the downstream end of the elements (7), said inlets being linked by channels (22) to a single outlet, itself linked to a flushing branch pipe (8) opening laterally outside the body (1). This distributor comprises a rotor (18) which, depending on its angular position, separately connects each of its inlets to the shared outlet of distributor.

    Abstract: An apparatus and process of filtering fluids, such as white water is provided for use in the place of an existing save-all device or downstream of an existing save-all device at a paper-making mill. The white water having contaminants in a suspended state is introduced into the filtration vessel and is withdrawn from the interior of the filter element positioned within the filtration vessel. To clean the filter element from the cake which has built up on the exterior surface of the filter element, a backflushing shock is applied to the interior of the filter element, forcing all cake settled on the exterior to be dislodged, thereby cleaning the filter element. The backflushing shock is delivered from a backflushing reservoir wherein the backflushing fluid is contained under pressure at a level at least slightly above the level of a pressure differential which has built up across the filter element. The shock is applied for a period of 1-2 seconds, during which time the backflush reservoir is emptied.

    Abstract: A filter unit using a bump-type filter is disclosed. Briefly stated, a chamber has a split fluid inlet conduit so that contaminated fluid, upon entering the chamber, is directed upwardly towards filter tubes and downwardly towards the bottom of the chamber. The fluid flow is diverted during startup so as to be directed only downward thereby enabling precoat of the filter element. Two tube sheets are utilized with incoming fluid in the vertically upward inlet conduit forcing incoming contaminated fluid to be deposited between the two tube sheets thereby. During operation contaminated fluid flows upwardly and downwardly towards the filter tubes so as to prevent disturbance of filter tubes as a result of turbulence in the chamber.

    Abstract: 1,181,273. Liquid filter. G. MAESTRELLI. 15 June, 1967 [15 Feb., 1967], No. 27618/67. Heading B1D. [Also in Divisions D1 and D2] A filter used in the solvent circuit of a coin-freed dry-cleaning machine comprises a plurality of filter elements D, made of wire wound on flat frames of moulded plastics, having lozenge-shaped cross-sections and being radially arranged about and supported by two or three rotatable hollow shafts F. After a washing cycle, during which solvent passes continually through the filter and back to the washing tub, the solvent flow is stopped and the shafts are rotated or arcuately reciprocated by a common motor (64), creating turbulence in the dirty solvent around the elements and thereby washing the used, absorbent, filter aid and solids therefrom. Periodically a sludge outlet (72) in the housing floor is opened. In Fig. 2 and Fig. 3 (not shown) the elements D intermesh and turbulence is concentrated in zone H. In Fig. 4 (not shown) the elements of the different assemblies do not intermesh and there is less turbulence. Within the limits of the filter housing, additional filter elements may be added to each ring of elements, and further complete rings of elements may be mounted axially above the first on each rotatable assembly. The ends of elements open into hollow radial arms of plastics spiders between which elements are clamped, the spiders (G) open into the interiors of shafts F and these discharge filtrate by outlets (70). Sludge discharged by outlet (72) passes to a distillation plant which recovers the filter aid.

    Abstract: A water filtration assembly (10) includes a first end cap (34) covering the first end of a housing (12) and a second end cap (36) covering the second end of the housing (12). The end surface (40) of each end cap (34 and 36) has a L-shaped cap recess therein with an axial leg (42) and a transverse leg (44) extending about the end face. A projection (30) at the first end of the housing (12) is disposed in engagement with the cap recess of the first end cap (34) as the end surface (40) of the first end cap (34) abuts the recess end surface (28) at the first end of the housing (12). In the same fashion, a projection (30) at the second end of the housing (12) is disposed in engagement with the cap recess of the second cap (36) as the end surface (40) of the second cap (36) abuts the recess end surface (28) at the second end of the housing (12). The end caps (34 and 36) are formed with a two sided shoulder (46) filling the corner between the axial (42) and transverse (44) legs of the cap recess. The projections (30) at the ends of the housing (12) are inserted into engagement with the cap recesses of the caps (34 and 36) as the distal ends (32) of the projections (30) abut the shoulders (46) in the cap recesses at the ends of the housing (12). The respective shoulders (46) are melted into a fusion bond between the distal end (32) of each projection (30) and each of the transverse legs (44) of the cap recesses. During this fusion, flash (48) is created and extends into the filter chamber. When the end caps (34 and 36) are fused in fluid tight engagement with the housing (12), the exterior surface (38) of each of the end caps (34 and 36) is spaced outwardly of the outer surface (14) of the housing (12) to define a step (x) between the outer surface (14) of the housing (12) and the exterior surface (38) of each of the end caps (34 and 36).
