Description
- This application is a continuation of U.S. application Ser. No. 10/894,191, filed Jul. 19, 2004, which is a continuation of U.S. application Ser. No. 10/268,600, filed Oct. 9, 2002, now U.S. Pat. No. 6,783,008, which is a continuation, under 35 U.S.C. § 120, of International Patent Application No. PCT/AU01/00387, filed on Apr. 6, 2001, under the Patent Cooperation Treaty (PCT), which was published by the International Bureau in English on Oct. 18, 2001, which designates the United States, and which claims the benefit of Australian Provisional Patent Application No. PQ 6801, filed Apr. 10, 2000.
- The present invention relates to a restraining system for hollow fibres used in membrane filtration systems.
- A number of different types of restraining systems usually in the form of a welded plastic mesh cage have been used in the past, however, these suffer from lack of rigidity when large apertures are required in the mesh to allow for fluid flows and are difficult to repair should any portion of the mesh be broken during transport, installation or use. While such known restraining systems are cheap and simple to manufacture they suffer from a lack of robustness in many required installations.
- The present invention seeks to overcome or at least ameliorate one or more of the disadvantages of the prior art or at least provide the public with a useful alternative.
- According to one aspect, the present invention provides a restraining system for hollow fibres including a plurality of longitudinally extending elements spaced from one another and supported by a number of discrete spacer elements, each spacer element extending generally transverse of said longitudinal elements such that in combination with said longitudinal elements they define a cage-like structure.
- For preference, the cage-like structure is tubular. Preferably, the longitudinal elements are rods and the spacer elements are in the form of rings. It will be appreciated that the rings may of any geometric shape and are not limited to a circular shape. Similarly, the tubular structure and rods may be of any geometric cross sectional shape.
- In one preferred form, each ring has a number of radially extending engagement formations for releasably engaging an associated rod. The formations may be in to form of part-circular opposed flanges spaced to provide a socket having an interference or snap-fit with the associated rod.
- In another preferred form, each ring has a number of radially extending cut-outs spaced around its periphery, each cut-out being sized and shaped to form an interference or snap-fit with an associated rod. Preferably, the internal surface of each ring is bevelled along each internal edge. For further preference, the internal surface of each ring is providing with a cushioning element. Preferably, the cushioning element is formed of a foam material and extends past the length of each ring at both ends so as to overlap the internal edges of each ring.
- The spacer elements may be formed from a number of sub-elements which are fixed together in use.
- The cut-outs or sockets are preferably equally-spaced around the periphery of the ring.
- For preference, the rods have a reduced diameter or width at the location where they engage with an associated spacer. Preferably, the reduced diameter is provided by a circumferential groove or slot.
- The components of the system are preferably formed of generally rigid plastics material, typically nylon and acrylonitrile butadiene styrene (ABS). The components can be moulded or machined to the desired configuration. The cut-outs are preferably part circular in cross section with an opening slightly smaller than the diameter to provide for snap-fitting retention of the rods.
- Preferred embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
-
FIG. 1 shows a perspective view of the restraining system according to one embodiment of the invention; -
FIG. 2 shows a perspective view of the spacer component of the restraining system ofFIG. 1 ; -
FIG. 3 shows an enlarged exploded perspective view of the restraining system ofFIG. 1 ; -
FIG. 4 shows a perspective view of the restraining system according to a second embodiment of the invention; -
FIG. 5 shows a perspective view of the snap ring component of the restraining system ofFIG. 4 ; -
FIG. 6 shows a perspective view of the adaptor ring component of the restraining system ofFIG. 4 ; -
FIG. 7 shows a perspective view of the restraining system according to a third embodiment; -
FIG. 8 shows a perspective view of the snap ring component of the restraining system ofFIG. 7 ; -
FIG. 9 shows a perspective view of the adaptor ring component of the restraining system ofFIG. 7 ; -
FIG. 10 shows a perspective view of the restraining system according to a fourth embodiment; -
FIG. 11 shows a perspective view of the snap ring component of the restraining system ofFIG. 10 ; -
FIG. 12 shows a perspective view of the adaptor ring component of the restraining system ofFIG. 10 ; and -
FIG. 13 shows an enlarged perspective view of the end of the restraining system ofFIG. 4 . - Referring to FIGS. 1 to 3, the restraining system comprises a generally tubular cage-
like structure 5 formed from a plurality of longitudinally extendingrods 6 spaced from one another and held in position by a number of longitudinally spaced and transversely extendingspacer rings 7. - Each
spacer ring 7 in this embodiment has a number ofengagement sockets 8 spaced equally around its periphery. Eachsocket 8 is formed by part-circular opposedflanges 9 spaced to provide an interference or snap-fit with the associatedrod 6. Thesockets 8 are slightly over semi-circular in shape to provide retention of therods 6. - Referring to FIGS. 4 to 13 of the drawings, each
ring 7 in these embodiments has a number of radially extending cut-outs 10 equally spaced around its periphery, each cut-out 10 being sized and shaped to form an interference or snap-fit with an associatedrod 6. The cut-outs 10 in this embodiment are slightly over semi-circular in shape to provide retention of therods 6. - The
rods 6 in this embodiment are provided with a circumferential groove or slot 11 to provide a reduced diameter/width at the location where they engage with thering 7. This serves to prevent longitudinal movement of therings 7 relative to therods 6. - Each end of the
tubular restraining structure 5 is provided with terminatingadaptor ring 12 which, in use, mounts thestructure 5 to apotting sleeve 16 or the like. Theadaptor ring 12 includes ainner ring 13 having a plurality ofopenings 14 to allow passage of fluid therethrough and a radial extendingcircumferential rib 15.Rib 15 is again provided with a corresponding number of cut-outs 16 as those provided on thespacer rings 7 for engaging with theends 17 ofrods 6. - As shown in the various embodiments, the
spacer rings 7 are preferably arranged in closely-spaced pairs. Further, the number of rods and rings can be varied according to restraint requirements. As best shown inFIG. 10 , the density of rod numbers can also be varied along the length of thetubular structure 5 where restraint requirements vary along the length. - The restraining system is used to restrain a bundle of hollow fibre membranes employed in filtration systems. The fibre bundle extends longitudinally within the tubular restraining system. The restraining system allows fluid flow to and from the hollow fibre membranes. Typically, the fibres extend between upper and lower headers which, together with the restraining system, can be used to form a replaceable fibre bundle module. In such arrangements, the cage has the added advantage of protecting the fibre bundle during deployment of the module.
- It will be appreciated, that further embodiments and exemplifications of the invention are possible without departing from the spirit or scope of the invention described.
