Description

[0001] FILTERASSEMBLY

[0002] Technical Field

[0003] The present disclosure relates generally to a filter assembly, and more specifically, to a filter assembly including a filter capsule and a support shell.

[0004] Background

[0005] Filter capsules are widely used in various applications, such as chemical-mechanical polishing (CMP). Conventional filter capsules may include various components made from rigid plastic materials. As a result, such conventional filter capsules may raise concerns regarding environmental sustainability. There is a need to reduce the amount of rigid plastic materials used to manufacture filter capsules without compromising their performance.

[0027] Detailed Description

[0028] In the following description, reference is made to the accompanying figures that form a part thereof and in which various embodiments are shown by way of illustration. It is to be understood that other embodiments are contemplated and may be made without departing from the scope or spirit of the present disclosure. The following detailed description, therefore, is not to be taken in a limiting sense.

[0029] In the following disclosure, the following definitions are adopted.

[0030] As used herein, “a,” “an,” “the,” “at least one,” and “one or more” are used interchangeably.

[0031] As used herein as a modifier to a property or attribute, the term “generally,” unless otherwise specifically defined, means that the property or attribute would be readily recognizable by a person of ordinary skill but without requiring absolute precision or a perfect match (e.g., within + / - 20 % for quantifiable properties).

[0032] The term “substantially,” unless otherwise specifically defined, means to a high degree of approximation (e.g., within + / - 10% for quantifiable properties) but again without requiring absolute precision or a perfect match.

[0033] As used herein, all numbers should be considered modified by the term “about.” The term “about,” unless otherwise specifically defined, means to a high degree of approximation (e.g., within + / - 5% for quantifiable properties) but again without requiring absolute precision or a perfect match.

[0034] As used herein, the terms “first” and “second” are used as identifiers. Therefore, such terms should not be construed as limiting of this disclosure. The terms “first” and “second” when used in conjunction with a feature or an element can be interchanged throughout the embodiments of this disclosure.

[0035] As used herein, “at least one of A and B” should be understood to mean “only A, only B, or both A and B.”

[0036] As used herein, the term “pressurized state” of a filter capsule refers to a state in which a fluid flowing through the filter capsule exerts a pressure on the filter capsule. The fluid may exert both radial and axial pressure to the filter capsule.

[0037] The present disclosure relates to a filter assembly. The filter assembly includes a filter capsule. The filter capsule includes a side wall extending along and about a first axis from a first wall end to a second wall end opposite to the first wall end. The side wall includes a film that is impermeable and flexible. The side wall defines a wall volume. The filter capsule further includes a first endcap connected to the side wall at the first wall end. The first endcap includes a first inner surface and a first outer surface opposite to the first inner surface. The first endcap further includes at least one coupling protrusion extending from the first outer surface opposite to the first inner surface. The first endcap further includes at least one first filter port disposed in fluid communication with the wall volume. The filter capsule further includes a second endcap connected to the side wall at the second wall end. The second endcap includes at least one second filter port disposed in fluid communication with the wall volume. The filter capsule further includes a filter cartridge disposed between the first endcap, the side wall, and the second endcap. The filter cartridge is connected to at least one of the first endcap and the second endcap. The filter cartridge includes filter media. The filter assembly further includes a support shell including a first shell end and a second shell end opposite to the first shell end. The first shell end is open. The support shell further includes a main portion extending along and about a second axis. The support shell further includes a first shell portion extending from the first shell end to the main portion. The support shell further includes a second shell portion extending from the main portion to the second shell end. The support shell further includes at least one coupling feature corresponding to the at least one coupling protrusion of the first endcap and disposed on the first shell portion. The at least one coupling feature is configmed to at least partially receive the at least one coupling protrusion. The support shell further includes at least one engagement feature disposed on the second shell portion and configured to engage with the second endcap. The support shell is configured to slidably and partially receive the filter capsule therein through the first shell end along the second axis. In an inserted uncoupled state of the filter capsule and the support shell, the at least one coupling protrusion of the first endcap is aligned with the at least one coupling feature of the support shell along the second axis. In the inserted uncoupled state, the filter capsule is rotatable relative to the support shell about the second axis in a first direction to transition the filter capsule and the support shell to a coupled state. In the coupled state, the at least one coupling feature at least partially receives the at least one coupling protrusion. In the coupled state, the filter capsule is substantially immovable relative to the support shell along the second axis. In the coupled state, the at least one engagement feature is disposed proximal to the second endcap. Furthermore, in the coupled state, the support shell fully surrounds the side wall of the filter capsule. Moreover, in the coupled state, the at least one first filter port and the at least one second filter port are substantially uncovered by the support shell.

[0038] The filter assembly of the present disclosure may allow minimization of rigid plastic components used in the manufacture of the filter capsule without compromising the performance of the filter capsule. Specifically, the support shell may enable the side wall of the filter capsule to include the film that is impermeable and flexible. The side wall including the film may reduce the amount of rigid plastics used to manufacture the filter capsule as compared to conventional filter capsules.

[0039] The support shell may support the filter capsule in both axial and radial directions so that the side wall remains protected from damage in a pressurized state of the filter capsule. Specifically, during use of the filter assembly in the coupled state when the filter capsule is in the pressurized state, the main portion of the support shell may engage with the side wall of the filter capsule, such that the support shell supports the filter capsule in the radial direction perpendicular to the first axis. In other words, the support shell may restrict excessive radial expansion of the side wall of the filter capsule, thereby mitigating damage (e.g., rupture) to the side wall. Further, during use of the filter assembly in the coupled state when the fdter capsule is in the pressurized state, the first shell portion of the support shell may engage with the at least one coupling protrusion of the first endcap, and the at least one engagement feature of the support shell may engage with the second endcap, such that the support shell further supports the filter capsule in the axial direction aligned with the first axis. In other words, the support shell may further restrict excessive axial expansion of the side wall, thereby mitigating damage (e.g., rupture) to the side wall. The support shell may therefore provide structural stability to the side wall during use of the filter assembly in the coupled state when the fdter capsule is in the pressurized state.

[0040] As the at least one first filter port and the at least one second filter port are substantially uncovered by the support shell in the coupled state, the filter assembly may also allow use of the filter capsule with existing filter interfaces, such as filter manifolds (e.g., a filter manifold used in a chemicalmechanical polishing process) or standard tubing without needing modifications to the existing filter interfaces. Further, the support shell may be reusable. In some cases, the filter capsule may be disposed of after use and the support shell may be reused with another filter capsule. The filter assembly may therefore promote environmental sustainability.

[0041] Referring now to the figures, FIG. 1 illustrates a schematic exploded perspective view of a filter assembly 100 according to an embodiment of the present disclosure.

[0042] The filter assembly 100 includes a filter capsule 101 and a support shell 102. The support shell 102 may be configured to slidably and partially receive the filter capsule 101 therein. Further, the support shell 102 may be configured to detachably couple with the filter capsule 101. Upon detachable coupling of the support shell 102 with the filter capsule 101, the support shell 102 may provide both axial and radial support to the filter capsule 101. Furthermore, upon detachable coupling of the support shell 102 with the filter capsule 101, the filter assembly 100 may be used with existing filter interfaces, such as filter manifolds (e.g., a filter manifold used in a chemical-mechanical polishing process) or standard tubing. The filter assembly 100 and components thereof will now be described in greater detail.

[0043] FIGS. 2 and 3 illustrate the filter capsule 101 according to an embodiment of the present disclosure. Specifically, FIG. 2 illustrates a schematic perspective view of the filter capsule 101, and FIG. 3 illustrates a schematic cross-sectional view of the filter capsule 101 taken along a line 1-1 of FIG. 2.

[0044] Referring to FIGS. 2 and 3, the filter capsule 101 includes a side wall 104, a first endcap 112, and a second endcap 130. The side wall 104 extends along and about a first axis 105 from a first wall end 106 to a second wall end 108 opposite to the first wall end 106. The side wall 104 defines a wall volume 110. The side wall 104 may have a hollow cylindrical shape.

[0045] The side wall 104 includes a film that is impermeable and flexible. In other words, the side wall 104 may be made from a flexible and fluid-impermeable film. The film may include any suitable material, such as a polymeric material, including, but not limited to, polyethylene, polypropylene, and so forth. Further, the side wall 104 may be thin. For example, the side wall 104 may have a thickness of less than 5 millimeters (mm). In some examples, the thickness of the side wall 104 may be from 0.1 mm to 1 mm.

[0046] The first endcap 112 is connected to the side wall 104 at the first wall end 106. The first endcap 112 includes a first inner surface 114 (shown in FIG. 3) and a first outer surface 116 opposite to the first inner surface 114.

[0047] The first endcap 112 further includes at least one first filter port 120 disposed in fluid communication with the wall volume 110. The at least one first filter port 120 may include a first passage 121 in fluid communication with the wall volume 110. In some embodiments, the first endcap 112 may further include a first primary portion 122. The at least one first filter port 120 maybe disposed on the first primary portion 122. The first primary portion 122 may extend from an end of the first endcap 112 along the first axis 105 toward the side wall 104.

[0048] The first endcap 112 further includes at least one coupling protrusion 118 extending from the first outer surface 116 opposite to the first inner surface 114. The at least one coupling protrusion 118 may have any suitable shape and dimensions. The shape and dimensions of the at least one coupling protrusion 118 may depend upon desired application attributes. For example, the shape and dimensions of the at least one coupling protrusion 118 may depend upon a maximum rated fluid pressure of the filter capsule 101. In some embodiments, the at least one coupling protrusion 118 may be integral with the first endcap 112. The first endcap 112 may further include a coupling portion 124 extending from the first primary portion 122 toward the side wall 104 along and about the first axis 105. The at least one coupling protrusion 118 may be disposed on the coupling portion 124.

The pair of coupling protmsions 118 is disposed on the coupling portion 124. The pair of coupling protrusions 118 is circumferentially spaced apart from each other about the first axis 105. The pair of coupling protrusions 118 may be disposed opposite to each other. In other words, the pair of coupling protrusions 118 may be circumferentially spaced apart from each other by 180 degrees. Furthermore, each coupling protrusion 118 from the pair of coupling protrusions 118 extends from the first outer surface 116 opposite to the first inner surface 114. Each coupling protrusion 118 from the pair of coupling protrusions 118 further extends circumferentially about the first axis 105.

[0050] The first endcap 112 may further include a first wall connecting portion 126 extending from the coupling portion 124 opposite to the first primary portion 122 along and about the first axis 105. The side wall 104 may be at least partially connected to the first outer surface 116 of the first endcap 112 at the first wall connecting portion 126. The side wall 104 may be, for example, mechanically fixed (e.g., welded) or thermally bonded to the first outer surface 116 at the first wall connecting portion 126.

[0051] The second endcap 130 is connected to the side wall 104 at the second wall end 108. The second endcap 130 includes at least one second filter port 136 disposed in fluid communication with the wall volume 110. The at least one second filter port 136 may include a second passage 137 in fluid communication with the wall volume 110. The second endcap 130 may further include a second primary portion 138. The at least one second filter port 136 may be disposed on the second primary portion 138. The second primary portion 138 may extend from an end of the second endcap 130 along the first axis 105 toward the side wall 104.

[0052] The second endcap 130 further includes a second inner surface 132 (shown in FIG. 3) and a second outer surface 134 opposite to the second inner surface 132. In the illustrated embodiment of FIGS. 2 and 3, the second endcap 130 further includes an endcap flange 143 extending from the second outer surface 134 opposite to the second inner surface 132. In some embodiments, the endcap flange 143 may be continuous. In some other embodiments, the endcap flange 143 may be discontinuous and define a series of spaced apart flanges. The second endcap 130 may further include an engagement portion 140 extending from the second primary portion 138 toward the side wall 104 along and about the first axis 105. The endcap flange 143 may be disposed on the engagement portion 140.

[0053] The second endcap 130 may further include a second wall connecting portion 142 extending from the engagement portion 140 opposite to the second primary portion 138 along and about the first axis 105. The side wall 104 may be at least partially connected to the second outer surface 134 of the second endcap 130 at the second wall connecting portion 142. The side wall 104 may be, for example, mechanically fixed (e.g., welded) or thermally bonded to the second outer surface 134 at the second wall connecting portion 142.

[0054] The filter capsule 101 further includes a filter cartridge 152 disposed between the first endcap 112, the side wall 104, and the second endcap 130. The filter cartridge 152 includes filter media. The filter media may include any suitable filtration media as per desired application attributes, including, for example, a carbon block, pleated filtration media, spirally-wrapped filtration media, non-woven media, or combinations thereof. In some embodiments, the filter cartridge 152 may further include a pair of cartridge endcaps connected to the filter media at opposite ends of the filter media. The first endcap 112, the side wall 104, and the second endcap 130 may form a fluid-tight casing around the filter media of the filter cartridge 152.

[0055] The filter cartridge 152 is connected to at least one of the first endcap 112 and the second endcap 130. In some embodiments, the filter cartridge 152 may be connected to the first endcap 112 and disconnected from the second endcap 130. For example, in the illustrated embodiment of FIG. 3, the filter cartridge 152 is mechanically fixed (e.g., welded) only to the first endcap 112. In some other embodiments, the filter cartridge 152 may be connected to the second endcap 130 and disconnected from the first endcap 112. In yet other embodiments, the filter cartridge 152 may be connected to both the first endcap 112 and the second endcap 130.

[0056] The filter capsule 101 may further include a first securement ring 144 disposed around the first wall connecting portion 126, such that at least a first securement portion 146 of the side wall 104 is disposed between the first secmement ring 144 and the first wall connecting portion 126. The first securement ring 144 may engage with the first securement portion 146 of the side wall 104. In some embodiments, the first securement ring 144 may be press-fitted to the first wall connecting portion 126 subsequent to the connection of the side wall 104 to the first wall connecting portion 126. The first securement ring 144 may improve the connection between the side wall 104 and the first endcap 112.

[0057] The filter capsule 101 may further include a second securement ring 148 disposed around the second wall connecting portion 142, such that at least a second securement portion 150 of the side wall 104 is disposed between the second securement ring 148 and the second wall connecting portion 142. The second securement ring 148 may engage with the second secmement portion 150 of the side wall 104. In some embodiments, the second securement ring 148 may be press-fitted to the second wall connecting portion 142 subsequent to the connection of the side wall 104 to the second wall connecting portion 142. The second securement ring 148 may improve the connection between the side wall 104 and the second endcap 130. The first and second securement rings 144, 148 may provide additional structural integrity to the filter capsule 101 by mitigating undesired detachment of the side wall 104 from the first and second endcaps 112, 130.

[0058] In some embodiments, the at least one first filter port 120 may be an outlet port. In some embodiments, the at least one second filter port 136 may be an inlet port. Specifically, in some embodiments, the at least one second filter port 136 may be an inlet port and the at least one first filter port 120 may be an outlet port of the filter capsule 101. In some other embodiments, the at least one second filter port 136 may be an outlet port and the at least one first filter port 120 may be an inlet port of the filter capsule 101.

Each stopping protrusion 128 from the pair of stopping protrusions 128 may extend from the first outer surface 116 opposite to the first inner surface 114 along the first axis 105. In some embodiments, each stopping protrusion 128 may be disposed on the coupling portion 124 and extend from the corresponding pair of coupling protrusions 118. The pair of stopping protrusions 128 may be disposed opposite to each other. In other words, the pair of stopping protrusions 128 may be circumferentially spaced apart from each other by 180 degrees.

[0068] 101 and the support shell 102 in an inserted uncoupled state 174 according to an embodiment of the present disclosure. In other words, the filter assembly 100 is in the inserted uncoupled state 174 inFIG. 6.

[0069] Referring to FIGS. 1 to 6, as discussed above, the support shell 102 is configured to slidably and partially receive the filter capsule 101 therein through the first shell end 156 along the second axis 155. The filter capsule 101 may be slidably and partially received within the filter capsule 101 and brought into the inserted uncoupled state 174. In the inserted uncoupled state 174, the first axis 105 may be substantially aligned with the second axis 155.

[0070] In the inserted uncoupled state 174 of the filter capsule 101 and the support shell 102, the at least one coupling protrusion 118 of the first endcap 112 is aligned with the at least one coupling feature

[0071] 165 of the support shell 102 along the second axis 155. In the illustrated embodiment of FIG. 6, in the inserted uncoupled state 174 of the filter capsule 101 and the support shell 102, the pair of insertion spaces 168 of the support shell 102 at least partially receives the pair of coupling protrusions 118 ofthe first endcap 112 and the pair of coupling protrusions 118 is aligned with the pair of coupling grooves

[0072] 166 (shown in FIG. 4) of the support shell 102 along the second axis 155.

[0073] In the inserted uncoupled state 174, the filter capsule 101 is rotatable relative to the support shell 102 about the second axis 155 in a first direction 178 to transition the filter capsule 101 and the support shell 102 to a coupled state 176 (shown in FIGS. 7 and 8). It may be noted that either or both of the filter capsule 101 and the support shell 102 may be rotated to transition the filter capsule 101 and the support shell 102 to the coupled state 176. Moreover, in the inserted uncoupled state 174, the pair of stopping protrusions 128 may restrict rotation of the filter capsule 101 relative to the support shell

[0074] 102 in a second direction 180 that is opposite to the first direction 178.

[0075] FIGS. 7, 8, and 9 illustrate the fdter assembly 100 with the filter capsule 101 and the support shell 102 in the coupled state 176 according to an embodiment of the present disclosure. In other words, the filter assembly 100 is in the coupled state 176 in FIGS. 7, 8, and 9. Specifically, FIG. 7 illustrates a schematic perspective view of the fdter assembly 100, FIG. 8 illustrates a cross-sectional view of the filter assembly 100 taken along a line 3-3 of FIG. 7, and FIG. 9 illustrates a schematic zoomed in cross- sectional view of a podion of the filter assembly 100 in the coupled state 176.

[0076] Referring to FIGS. 7 to 9, in the coupled state 176, the at least one coupling feature 165 at least partially receives the at least one coupling protrusion 118. Specifically, in the illustrated embodiment of FIG. 8, in the coupled state 176, the pair of coupling grooves 166 at least partially receives the pair of coupling protrusions 118. In the coupled state 176, the pair of stopping protrusions 128 may restrict further rotation of the filter capsule 101 relative to the support shell 102 about the second axis 155 in the first direction 178.

[0077] In the coupled state 176, the filter capsule 101 is substantially immovable relative to the support shell 102 along the second axis 155. The first shell portion 160 of the support shell 102 may engage with the at least one coupling protrusion 118 to restrict movement of the filter capsule 101 with respect to the support shell 102 along the second axis 155.

[0078] In the coupled state 176, the at least one first filter port 120 and the at least one second filter port 136 are substantially uncovered by the support shell 102. The at least one first filter port 120 and the at least one second filter port 136 being substantially uncovered by the support shell 102 may allow the filter capsule 101 to interface with existing filter interfaces, such as fdter manifolds, in the coupled state 176 of the filter assembly 100. In some embodiments, in the coupled state 176, the first endcap 112 and the second endcap 130 may be substantially uncovered by the support shell 102. This may further improve compatibility of the filter assembly 100 with the existing filter interfaces in the coupled state 176.

[0079] In the coupled state 176, the support shell 102 fully surrounds the side wall 104 of the filter capsule 101. Specifically, the main portion 162 of the support shell 102 may fully surround the side wall 104. Further, in the coupled state 176, the at least one engagement feature 171 is disposed proximal to the second endcap 130. As shown in FIGS. 8 and 9, in some embodiments, in the coupled state 176, the shell flange 172 of the support shell 102 is disposed proximal to the endcap flange 143 of the second endcap 130. Further, as shown in FIG. 9, in some embodiments, in the coupled state 176, the shell flange 172 may be spaced apart from the endcap flange 143 along the second axis 155. In other words, in the coupled state 176, the shell flange 172 and the endcap flange 143 may define a gap 175 therebetween along the second axis 155.

[0080] During use of the filter assembly 100 in the coupled state 176 when the filter capsule 101 is in a pressurized state, the main portion 162 of the support shell 102 may engage with the side wall 104 of the filter capsule 101 , such that the support shell 102 supports the filter capsule 101 in a radial direction 182 perpendicular to the first axis 105. In other words, the support shell 102 may restrict excessive radial expansion of the side wall 104 of the filter capsule 101, thereby mitigating damage (e.g., rupture) to the side wall 104. In some embodiments, the main portion 162 of the support shell 102 is non- apertured. That is, the main portion 162 may be substantially continuous and void of any through-holes. The non-apertured configmation of the main portion 162 may reduce or prevent undesired damage to the side wall 104 which may otherwise occur due to apertures in the main portion 162.

[0081] Further, during use of the filter assembly 100 in the coupled state 176 when the filter capsule 101 is in the pressurized state, the first shell portion 160 of the support shell 102 may engage with the at least one coupling protrusion 118 of the first endcap 112, and the at least one engagement feature 171 of the support shell 102 may engage with the second endcap 130, such that the support shell 102 further supports the filter capsule 101 in an axial direction 184 aligned with the first axis 105. In other words, the support shell 102 may further restrict excessive axial expansion of the side wall 104, thereby mitigating damage (e.g., rupture) to the side wall 104.

[0082] In the illustrated embodiment of FIGS. 7, 8, and 9, during use of the filter assembly 100 in the coupled state 176 when the filter capsule 101 is in the pressurized state, the pair of coupling members 164 of the support shell 102 may engage with the pair of coupling protrusions 118 of the first endcap 112, and the shell flange 172 of the support shell 102 may engage with the endcap flange 143 of the second endcap 130, such that the support shell 102 further supports the filter capsule 101 in the axial direction 184 aligned with the first axis 105. The gap 175 (shown in FIG. 9) may substantially reduce to zero in the pressurized state of the filter capsule 101.

[0083] The filter assembly 100 may allow minimization of rigid plastic components used in the manufacture of the filter capsule 101 without compromising the performance of the filter capsule 101. Specifically, the support shell 102 may enable the side wall 104 of the filter capsule 101 to include the film that is impermeable and flexible. The side wall 104 including the film may reduce the amount of rigid plastics used to manufacture the filter capsule 101 as compared to conventional fdter capsules. The support shell 102 may support the filter capsule 101 in both axial and radial directions so that the side wall 104 remains protected from damage in the pressurized state. The support shell 102 may provide structural stability to the side wall 104 during use of the filter assembly 100 in the coupled state 176 when the filter capsule 101 is in the pressurized state. Further, the support shell 102 may be reusable. The filter assembly 100 may therefore promote environmental sustainability.

Specifically, the at least one opening 206 may include a pair of openings 206 corresponding to the pair of second filter ports 136. The pair of openings 206 may be configured to partially receive the pair of second filter ports 136 therethrough in each of the inserted uncoupled state 174 and the coupled state 176 of the filter capsule 201 and the support shell 202. As discussed above, the fdter capsule 201 may be rotated relative to the support shell 202 in the first direction 178 to transition the filter assembly 200 from the inserted uncoupled state 174 (shown in FIG. 11 A) to the coupled state 176 (shown in FIG. 11B).

[0089] Further, the at least one coupling feature 165 may include at least one coupling slot 208 circumferentially extending about the second axis 155. The support shell 202 may further include at least one insertion slot 210 corresponding to the at least one coupling slot 208.

As shown in FIG. 11B, in the coupled state 176, the corresponding coupling slot 208 may at least partially receive the at least one coupling protrusion 118.

[0091] FIGS. 12, 13A, and 13B illustrate a filter assembly 300 according to another embodiment of the present disclosure.

The filter capsule 301 is similar to the filter capsule 101 of FIGS. 2 and 3, with like components designated by like reference characters. Further, the support shell 302 is similar to the support shell 202 of FIGS. 10, 11 A, 11B, with like components designated by like reference characters.

[0092] Specifically, FIG. 12 illustrates a schematic exploded perspective view of the filter assembly 300, FIG. 13A illustrates a schematic perspective view of the fdter assembly 300 in the uncoupled state 174, and FIG. 13B illustrates a schematic perspective view of the filter assembly 300 in the coupled state 176.

[0093] In the illustrated embodiment of FIGS. 12, 13 A, and 13B, the side wall 104 is at least partially connected to the first inner surface 114 (see FIG. 3) of the first endcap 112.
