Definitions
- the present invention relates to membrane filtration modules that are more sanitary and are easier to replace and install than presently available filtration modules. More particularly, the present invention relates to membrane filtration modules formed from a filtration cartridge, a retaining bowl and a manifold joined together.
- the control of particulate contaminants in a filtration process such as in the semiconductor industry requires the use of ultraclean filters having membranes that remove submicron particles. It is well known that any particle that is deposited on a semiconductor wafer produces a defect when the particle is sufficiently large. Typically in the semiconductor industry, failed defects can be produced by particles as small as about one tenth of the smallest features of the semiconductor chip. Therefore, membrane filters are used in every process step for producing semiconductor chips to purify both working liquids and gases.
- a second filtration modular design locates all of the connections at the same end of the module.
- the feed and permeate ports are typically horizontally oriented at the top or "head" end of the module on opposite sides thereof. Due to their shape, these modules are referred to as having a T, L or U configuration.
- This configuration facilitates connection of the head to the remaining portion of the filtration module comprising the bowl and the filtration cartridge positioned within the bowl.
- the bowl and filtration cartridge comprise separate elements.
- the filtration cartridge and the bowl are separately secured to and sealed to the manifold head.
- the bowl and cartridge are separately removed from the head.
- This separate removal requires that the bowl be moved a distance substantially greater than the entire length of the cartridge in order to expose the cartridge to permit its removal. Thereafter, the exposed cartridge is removed by hand or with a hand tool. Since the filter cartridge is saturated with the liquid being filtered which is often times corrosive or toxic, the cartridge removal step presents a danger to the worker. In addition, since the bowl must be moved the length of the cartridge, the space within which the bowl and cartridge are positioned must accommodate this removal step.
- a filtration module construction which avoids the need to remove the filtration cartridge separately than the bowl from the manifold - ⁇ - while permitting the filter cartridge and bowl to be removed from a manifold as a single unit.
- Such a construction would promote ease of separating the cartridge and bowl from the manifold, would eliminate the danger to the worker in removing the filtration cartridge subsequent to filtration and would reduce the space required to install the filtration module.
- the cartridge and the bowl as a unitary structure and securing that structure to the manifold, the problem of the cartridge becoming dislodged from the manifold when subjected to back pressure is avoided.
- a filtration module comprising a manifold, and the combination of a filtration cartridge and bowl wherein the filtration cartridge and bowl are locked together to be installed and removed as one piece from the manifold.
- the filter cartridge and bowl are joined together by application of a force in a single direction at a given time, that is, in a vertical direction.
- the bowl and filter cartridge are joined together by a snap fit wherein mating elements on the bowl and filter cartridge are shaped so the elements are held together by friction which requires a force to decouple the bowl and filter cartridge.
- This construction permits the decoupling of the filtration cartridge and bowl from the manifold in one step.
- the coupling means can be constructed so that, when it is desired to remove the filtration cartridge and bowl from the manifold, the filtration cartridge and bowl can be removed as one piece with a threaded locking ring.
- Fig. 1 is a side view of a bowl and filter cartridge of the present invention.
- Fig. 2 is a top perspective view of an attachment to form a bowl of this invention.
- Fig. 3 a is a side view of an alternative bowl and filter cartridge of this invention.
- Fig. 4 is a side view of an alternative filter cartridge of this invention.
- Fig. 5 is a side view of the filter cartridge of Fig. 4 positioned within a bowl of this invention.
- Fig. 6 shows a first embodiment of the present invention for retaining the filter cartridge and bowl in a manifold in cross section.
- Fig. 7 shows a second embodiment of the present invention for retaining the filter cartridge and bowl in a manifold in cross section.
- Fig. 8 shows a further embodiment of the present invention for retaining the filter cartridge and bowl in a manifold in cross section.
- Fig. 9 shows a further embodiment of the present invention for retaining the filter cartridge and bowl in a manifold in cross section.
- the present invention provides a filtration module formed of a manifold, a filtration cartridge and a bowl.
- the manifold provides fluid pathways for fluid feed into the filtration cartridge and permeate removal from the filtration cartridge.
- the bowl provides a means of storing fluid feed to permit its introduction into the filtration cartridge or to store permeate from the filtration cartridge to be directed to the manifold and then from the filtration module.
- Fluid feed can be introduced into the filtration cartridge through the manifold either from the outside of the filtration cartridge or from within the interior of the filtration cartridge.
- the fluid in the bowl adjacent the filtration cartridge can be either fluid feed or permeate. In any event, the fluid feed is introduced from a manifold into the filtration module and permeate is removed from the filtration module from the manifold.
- the filtration module and bowl are constructed so that they are sealed with the manifold or removed from contact with the manifold as one piece.
- the bowl and filtration module are formed from two pieces which are interlocked together by moving the bowl and filter cartridge in only one direction relative to each other at a given time. After the bowl and filtration module have been connected to the manifold, they are locked together so that, during use in filtering of fluid, they do not become separated. Subsequent to a filtration, the bowl and filtration module are removed from the manifold as a single piece rather than as two separate pieces. Since the bowl and filtration module are removed together, the filtration module need not be removed from the bowl. Thus, a space substantially equal to the length of the filtration module and the bowl together need not be provided.
- apparatus of this invention includes a bowl 10, a filter cartridge 12 and a retaining ring 14.
- the filter cartridge 12 including a filter 14a, a fitting 16 and a flange 18.
- the flange 18 fits into the retaining ring 14 by being locked into keyway 20 of prong 22.
- the flange 18 also is positioned on slots 24 and 26 of prongs 28 and 30.
- Retaining ring 14 is fixedly positioned on bowl 10 by any convenient means such as by being adhered thereto or formed with the bowl 10 as one piece such as by molding. Referring to Fig.
- the retaining ring 14b is fixedly positioned on bowl 10 and can comprise two or more (preferably three) prongs 32 and 34 all of which include a keyway 36 into which fits flange 38 of filter cartridge 40.
- Filter cartridge 40 also includes a fitting 42 to effect sealed fluid communication between the filter cartridge 40 and a manifold (not shown).
- a filter cartridge 50 of this invention which comprises a filter 52, a fitting 54 and a flange 56 which is positioned on the outside surface of the filter 52 rather than on a portion of the fitting as shown in Fig. 1.
- the flange 56 functions in the same manner as the flange 18 of Fig. 1.
- the retaining ring 14 is sealed to the bowl 60.
- the bowl 60 includes a retaining ring 14 having the prongs 28, 26 (not shown) of Fig. 2 and 56.
- the prongs function in the same manner as described above with reference to Figs. 1 and 2.
- a filter housing 1 is of a U line design, although the invention will function equally well with inline and other such housing designs.
- the housing 1 is formed of a bowl 2 and a manifold 3.
- a threaded ring 4 is substantially fixed in its position upon the bowl 2.
- the threads 5 of the ring 4 mate and thread easily with corresponding threads 6 formed on the manifold 3.
- the first component 2 is a cartridge bowl and the second component 3 is a manifold.
- the bowl 2 includes a retaining ring 14 having the prongs 28, 26 (not shown) and 22 of Fig. 2.
- the prongs function in the same manner as described above with reference to Figs. 1 and 2.
- the ring 4 is substantially fixed in its position relative to the first component in this case the bowl 2, i.e. it cannot move any substantial distance along the length of the bowl 2.
- the ring 4 carries or drives the first component or bowl 2 into affirmative contact with the second component or manifold 3.
- the first component or bowl 2 is positively carried or driven away from the second component or manifold 3.
- the device used to fix the position of the ring 4 to one of the two components can be a variety of devices.
- the ring 4 is loosely fixed to the first component 2, i.e. the bowl in this embodiment, using a key 7 formed on the ring 4 which key 7 mates and is held within a keyway 8 formed in the bowl 2.
- the ring 4 can be rotated by hand.
- the ring 4 is shown with a knurled feature 9 on a portion of its outer side surface.
- the use of knurling or other such devices for providing an easy, slip-free surface to the ring is well known and may be used in this invention.
- lugs or tapered surfaces on the outer surface of the ring may be used to allow one to attach a wrench or other device for moving the ring relative to the other threaded component. While it is contemplated in the preferred embodiments of this present invention that no wrench or other device is necessary to move the ring, it is still within the scope of the present invention.
- the bowl 14a includes a retaining ring 14 having the prongs 28, 26 (not shown) and 22 of Fig. 2.
- the prongs function in the same manner as described above with reference to Figs. 1 and 2 to retain the filter cartridge 50.
- the ring 4 is attached to the manifold 3 rather than the bowl 2 of Figure 6.
- the keyway 8 is formed in the manifold surface and the key 7 of the ring 4 is trapped within it.
- the threads 5 of the ring 4 mate with the threads 6 of the manifold 3 to drive the manifold 3 and bowl 2 together and apart.
- bracket or surface to which the manifold is mounted may have a portion which extends over the ring and thereby traps it to the manifold when the manifold is secured in place.
- Other such embodiments will be obvious to one of ordinary skill in the art.
- the bowl 14a includes a retaining ring 14 having the prongs 28, 26 (not shown) and 22 of Fig. 2.
- the prongs function in the same manner as described above with reference to Figs. 1 and 2 to retain the filter cartridge 50.
- the threads 18a of the ring 14 mate with the threads 16a of the manifold 13a to drive the bowl 14a and manifold 13a relative to one another.
- Figure 9 shows a further embodiment of the present invention and clearly demonstrates what is meant by the term “substantially fixed”.
- the ring 41a is mounted to the bowl 42a and retained to the bowl 42a by a ridge 43 a, which in this embodiment is a circular ring positioned along a portion of the outer surface of the side wall of the bowl 42a.
- the bowl 42 also has a lip 44a which extends outward from the upper portion of the outside surface of the side wall of the bowl 42a.
- the threads 45a of the ring 41a mate with the threads 46a of the manifold 47a. As can be seen, there is substantial room between the lip 44a and the ridge 43 along the length of the side wall of the bowl 42a.
- this embodiment still shows the ring 41a being in a substantially fixed position relative to the bowl 42a.
- substantially fixed it is meant that the ring is retained to one component of the housing in such a manner that its travel along the length of the component is less than 50% of that length.
- the amount of travel allowed to the ring relative to the length of the component is less than 25% of the component length.
- the length of travel of the ring relative to the length of the component should be such that at least for a portion of the rotation of the threads between the ring and the second component, there is a driving force caused by the threads of the ring to move the components affirmatively.
- the length of travel is limited such that the threads of the ring will begin to rotate against those of the other component for some set (as desired by the manufacturer) distance before the ring threads are in a position to positively drive the two components together or apart. In this way, one is staggering the load placed upon the ring making its use easier, quicker and simpler.
- one can use other devices should as band clamps, lugs, etc to retain the ring in its desired substantially fixed position relative to the component to which it is mounted.
- the device used to retain the ring in a substantially fixed position relative to the component to which it is attached is not critical so long as it allows the two components to adequately move relative to each other to form a liquid tight seal and to allow the ring to retained in a manner so that it affirmatively drives the two components at least a portion of the way together and apart as desired.
- the media includes but is not limited to of flat sheet membrane, spiral wound flat sheet membrane, pleated flat sheet membrane, spiral pleated flat sheet membrane, hollow fiber membrane, depth filter media such as spiral wound continuous fiber depth filter media, sintered metal filter media, ceramic media, particulate media containing an active capture material such as resin or ceramic beads or a membrane with ligands for removing selected materials from the fluid attached to their surfaces, ion exchange media such as anion resin, cation resin or mixtures of the two alone or incorporated into a membrane structure and combinations of any of these.
- the bowl and manifold may be made of a plastic, preferably a thermoplastic including polyolefins such as polyethylenes including ultrahigh molecular weight polyethylenes, polypropylenes; copolymers or terpolymers of polyolefins; nylons; PTFE resin, PFA, PVDF, ECTFE, and other fluorinated resins, particularly perfluorinated thermoplastic resins; polycarbonates; metallocene derived polymers, polysulphones; modified polysulphones such as polyethersulphone, polyarylsulphones or polyphenylsulphones; any glass or other reinforced plastic; or a metal such as stainless steel, aluminum, copper, bronze, brass, nickel, chromium or titanium or alloys or blends thereof.
