[0039] Such as Figures 1 to 3As shown, some embodiments of the present application provide a capsule filter installation fixture, including a bottom plate 1, a first clamping unit, and a second clamping unit. Among them, the first clamping unit and the second clamping unit are relatively installed on the bottom plate 1. The first clamping unit includes a support member and a first engaging member installed on the support member, and the first engaging member can move relative to the support member to switch between a first position and a second position; the second clamping unit includes a second engaging member.

[0040] When the first engaging member is in the first position, it is convenient to clamp the liquid inlet end 21 of the capsule filter 2. After the liquid inlet end 21 of the capsule filter 2 is clamped on the first engaging member, the first engaging member drives the capsule filter 2 to move from the first position to the second position. When the capsule filter 2 moves to the second position, the second engaging member engages the liquid outlet end 22 of the capsule filter 2, so that the liquid outlet end 22 of the capsule filter 2 is limited on the second engaging member, completing the installation of the capsule filter 2. The above settings are beneficial to reducing the installation difficulty of the capsule filter 2 and reducing the working intensity of the staff during the installation process of the capsule filter 2.

[0041] It should be noted that the liquid inlet end 21 of the capsule filter 2 is detachably connected to the first engaging member, and the liquid outlet end 22 of the capsule filter 2 is detachably connected to the second engaging member. The distance between the axis of the capsule filter 2 and the upper surface of the bottom plate 1 can be set within the range of the maximum radius of the capsule filter 2 plus 10 mm for easy disassembly of the capsule filter 2.

[0042] Exemplarily, when the first engaging member switches between the first position and the second position, the first engaging member rotates relative to the support member in a vertical plane, that is, the first engaging member switches from the first position to the second position by rotating. This vertical plane is a plane perpendicular to the upper surface of the bottom plate 1, and the axis of the capsule filter 2 is located in this vertical plane.

[0043] In some embodiments, the support member is set as a first connecting seat 3 and a second connecting seat 4 connected to each other, and the first engaging member is a rotating member 5 rotatably connected to both the first connecting seat 3 and the second connecting seat 4. Among them, the second connecting seat 4 is installed on the first connecting seat 3 by screws. The connection of the rotating member 5 with the capsule filter 2 is to drive the capsule filter 2 to rotate from the first position to the second position.

[0044] Exemplarily, the first connecting seat 3 is installed on the bottom plate 1 by screws.

[0045] As Figures 4 to 6As shown, in some embodiments, the rotating member 5 includes a rotating portion 51 and a connecting portion 52 which are connected to each other. A first accommodating cavity is formed between the connected first connecting seat 3 and the second connecting seat 4. The rotating portion 51 is located in the first accommodating cavity and can rotate in the first accommodating cavity. The second connecting seat 4 is further provided with a limiting hole 41 communicating with the first accommodating cavity, and the connecting portion 52 extends out of the limiting hole 41, so that the limiting hole 41 can limit the rotation of the rotating member 5, that is, limit the rotation of the rotating member 5 from the first position to the second position.

[0046] Exemplarily, the rotating portion 51 can be set as a spherical structure, and the first accommodating cavity for accommodating the rotating portion 51 can also be set as a spherical structure, so that the rotating portion 51 can rotate in the first accommodating cavity. Each of the first connecting seat 3 and the second connecting seat 4 is provided with a hemispherical groove, and after the two are connected together, a spherical accommodating cavity for accommodating the rotating member 5 is formed. Generally, there is a clearance fit between the rotating portion 51 and the first accommodating cavity, and the clearance size can be set to 0.25 - 0.4 mm.

[0047] The connecting portion 52 can be set as a cylindrical structure, the maximum diameter of the cylindrical structure is smaller than the maximum diameter of the spherical structure, and the maximum diameter of the limiting hole 41 for installing the connecting portion 52 is also smaller than the maximum diameter of the spherical structure, which is beneficial to prevent the rotating portion 51 from falling off from the first accommodating cavity during rotation.

[0048] In some embodiments, in order to install the capsule filter 2, a relief inclined surface 42 is provided on one side of the second connecting seat 4 facing the second clamping unit, and the relief inclined surface 42 is located at the upper part of the second connecting seat 4. The part of the limiting hole 41 located on the relief inclined surface 42 expands in a direction away from the bottom plate 1, so that the rotating member 5 can rotate to the first position. When the rotating member 5 is in the first position, at this time, the rotating member 5 is inclined upward relative to the bottom plate 1. When installing the capsule filter 2, the relief inclined surface 42 is used to make way for the capsule filter 2 to prevent the rotating member 5 from being unable to install the capsule filter 2 in the first position.

[0049] It should be noted that after both the first clamping unit and the second clamping unit are connected to the capsule filter 2, that is, after the rotating member 2 rotates to the second position, the axis of the rotating member 5 is parallel to the bottom plate 1, and the part of the limiting hole 41 not located on the relief inclined surface 42 has the function of supporting the rotating member 5.

[0050] Exemplarily, the inclination angle of the relief inclined surface 42 is the same as the angle by which the rotating member 5 rotates relative to the bottom plate 1 when in the first position.

[0051] In some embodiments, an installation hole 53 is formed on one side of the connecting portion 52 facing the second clamping unit. The liquid inlet end 21 of the capsule filter 2 is connected to the connecting portion 52 of the rotating member 5 by inserting into the installation hole 53, thereby radially limiting the liquid inlet end 21 of the capsule filter 2. An inlet liquid hole 54 penetrating through the rotating member 5 is further provided on the rotating member 5, and the inlet liquid hole 54 is communicated with the installation hole 53 so that the inlet liquid hole 54 is communicated with the liquid inlet end 21 of the capsule filter 2.

[0052] Exemplarily, the installation hole 53 is in interference fit with the liquid inlet end 21, and the inner diameter of the installation hole 53 can be set to be 0.5 - 1 mm smaller than the outer diameter of the liquid inlet end 21. Moreover, the depth of the installation hole 53 can be set to be 3 - 5 mm greater than the length of the liquid inlet end 21.

[0053] In some embodiments, a liquid inlet joint 6 is connected to the side of the first connecting seat 3 facing away from the second clamping unit. The liquid inlet joint 6 is used to connect to the inlet manifold for inputting the liquid to be filtered, and the liquid inlet joint 6 is communicated with the first accommodating cavity formed between the first connecting seat 3 and the second connecting seat 4. When both the first clamping unit and the second clamping unit are connected to the capsule filter 2, the liquid inlet joint 6 is communicated with the inlet liquid hole 54 of the rotating member 5 located in the first accommodating cavity. Since the inlet liquid hole 54 is communicated with the liquid inlet end 21 of the capsule filter 2, the liquid inlet joint 6 is communicated with the liquid inlet end 21 of the capsule filter 2, so as to input the liquid to be filtered in the inlet manifold into the capsule filter 2 for filtration.

[0054] It should be noted that the diameter of the inlet liquid hole 54 is larger than the inner diameter of the liquid inlet joint 6, and the difference between the two can be set within 3 mm, so as to reduce the machining precision of the first connecting seat 3, the second connecting seat 4 and the rotating member 5, which is beneficial to reducing costs.

[0055] The diameter R of the rotating portion 51 of the rotating member 5 1 can be determined by the following formula:

[0056]

[0057] where r 2 is the radius of the inlet liquid hole 54, and A is the angle of rotation of the rotating member 5 relative to the bottom plate 1 when the rotating member 5 is in the first position.

[0058] Exemplarily, one end of the liquid inlet joint 6 connected to the first connecting seat 3 is provided with a taper pipe thread, and the end facing away from the first connecting seat 3 is provided with a flared pipe joint for connecting to a pipeline of an inlet manifold with a size of 3 / 8 or 1 / 2.

[0059] It should be noted that a sealing ring groove is provided on the hemispherical groove of the first accommodating cavity formed on the first connecting seat 3 for installing a sealing ring to seal the liquid flowing into the first accommodating cavity from the liquid inlet joint 6 and prevent the liquid from flowing out of the first accommodating cavity. The depth of the sealing ring groove can be set to be 0.5 - 0.1 mm less than the wire diameter of the sealing ring, and the outer diameter of the sealing ring groove can be set to be 0.1 - 0.5 mm less than the outer diameter of the sealing ring. The wire diameter of the sealing ring can be set to be 3 - 5.55 mm, and the inner diameter can be set to be 0.6 - 1 mm less than the diameter of the rotating part 51.

[0060] As Figure 7 shown, in some embodiments, the second clamping unit includes a third connecting seat 7, and the second engaging part is a first limiting groove 71 and a second limiting groove 72 provided on the third connecting seat 7 and communicating with each other, and the first limiting groove 71 and the second limiting groove 72 axially limit at least the liquid outlet end 22 of the capsule filter 2.

[0061] Specifically, the first limiting groove 71 is opened on the upper surface of the third connecting seat 7, the second limiting groove 72 is opened on one side of the third connecting seat 7 close to the first clamping unit, and the second limiting groove 72 communicates with the upper surface of the third connecting seat 7, so that when the capsule filter 2 rotates to the second position, the liquid outlet end 22 of the capsule filter 2 is embedded in the first limiting groove 71 and the second limiting groove 72. Among them, the first limiting groove 71 axially limits the liquid outlet end 22 of the capsule filter 2, and the second limiting groove 72 radially limits the liquid outlet end 22 of the capsule filter 2.

[0062] Exemplarily, the third connecting seat 7 is installed on the bottom plate 1 by screws.

[0063] Specifically, the liquid outlet end 22 of the capsule filter 2 is of a disc structure, and a cylindrical structure with a diameter smaller than the disc structure is connected to the disc structure. When the liquid outlet end 22 of the capsule filter 2 is connected to the installation part, the disc structure is embedded in the first limiting groove 71, and the cylindrical structure abuts against the inner wall of the second limiting groove 72. The width of the second limiting groove 72 can be set to be 0.5 - 1 mm larger than the outer diameter of the cylindrical structure.

[0064] It should be noted that a sealing ring 23 is installed on the end face of the disc structure of the liquid outlet end 22 of the capsule filter 2. When the disc structure is embedded in the first limiting groove 71, the sealing ring completely abuts against the first inner wall of the first limiting groove 71, and due to the effect of the sealing ring, the side of the disc structure opposite to the side where the sealing ring 23 is installed completely abuts against the second inner wall of the first limiting groove 71 opposite to the first inner wall.

[0065] Exemplarily, when both the first clamping unit and the second clamping unit are connected to the capsule filter 2, that is, when the capsule filter 2 rotates to the second position, the second limiting groove 72 plays a certain supporting role for the liquid outlet end 22 of the capsule filter 2.

[0066] like Figure 8 and Figure 9 As shown, in some embodiments, a cover plate 8 is installed on the third connecting seat 7, and an opening 81 connected to the second joining component is formed on the cover plate 8, that is, the opening 81 is connected to the first limiting groove 71 and the second limiting groove 72 on the third connecting seat 7, so that the liquid outlet end 22 of the capsule filter 2 can be connected to the first limiting groove 71 and the second limiting groove 72 through the opening 81 on the cover plate 8.

[0067] A second accommodating cavity is formed between the cover plate 8 and the third connecting seat 7, and the limiting plate 9 is located in the second accommodating cavity and can move in the second accommodating cavity. After the liquid outlet 22 of the capsule filter 2 is engaged with the second engaging component, the limiting plate 9 is moved to the upper part of the liquid outlet 22 to limit the radial direction of the liquid outlet 22, so as to prevent the liquid outlet 22 of the capsule filter 2 from being separated from the second engaging component during operation.

[0068] Exemplarily, a mounting groove 82 is provided on one side of the cover plate 8 facing the third connecting seat 7 , so that a second accommodating cavity is formed after the cover plate 8 is connected to the third connecting seat 7 .

[0069] Specifically, a guide groove 821 is provided in the mounting groove 82 on the cover plate 8, and a guide boss 91 is provided on the limiting plate 9 to cooperate with the guide groove 821. When the limiting plate 9 is located in the second accommodating cavity, the guide boss 91 is located in the guide groove 821, guiding the movement of the limiting plate 9 in the second accommodating cavity, and also preventing the limiting plate 9 from shaking in the second accommodating cavity.

[0070] It should be noted that, before the liquid outlet 22 of the capsule filter 2 is engaged with the second engagement member, the limiting plate 9 is moved so that the limiting plate 9 does not block the opening on the cover plate 8. The limiting plate 9 is also provided with a limiting boss 92, which can prevent the limiting plate 9 from falling off from the opening of the second accommodating cavity.

[0071] In some embodiments, a liquid outlet connector 10 is connected to the side of the third connection seat 7 facing away from the first clamping unit, and the liquid outlet connector 10 is used to connect to a liquid outlet manifold that outputs the liquid filtered by the capsule filter 2, and the liquid outlet connector 10 is in communication with the mounting portion. When the first clamping unit and the second clamping unit are both connected to the capsule filter 2, the liquid outlet connector 10 is in communication with the liquid outlet end 22 of the capsule filter 2 located in the mounting portion, so that the liquid filtered by the capsule filter 2 is transported to the liquid demand location via the liquid outlet manifold connected to the liquid outlet connector 10.

[0072] Exemplarily, one end of the liquid outlet connector 10 connected to the third connecting seat 7 is configured as a tapered pipe thread, and the end away from the third connecting seat 7 is configured as a flared pipe connector for connecting a pipeline of a liquid outlet manifold of size 3 / 8 or 1 / 2.

[0073] In the actual application of this application, when installing the bladder filter 2, first, move the limit plate 9 so that the opening of the cover plate 8 is not blocked. Subsequently, rotate the rotating member 5 to the first position. At this time, the mounting hole 53 of the rotating member 5 is inclined upward relative to the bottom plate 1. Subsequently, insert the liquid inlet end 21 of the bladder filter 2 into the mounting hole 53 of the rotating member 5 to install the bladder filter 2 on the rotating member 5. Subsequently, rotate the rotating member 5 to rotate the bladder filter 2 from the first position to the second position, so that the liquid outlet end 22 of the bladder filter 2 is embedded in the first limiting groove 71 and the second limiting groove 72 of the third connecting seat 7. Finally, move the limit plate 9 above the liquid outlet end 22. At this time, the limit plate 9 blocks the opening of the cover plate 8, and the installation of the bladder filter 2 is completed.

[0074] When it is necessary to disassemble the bladder filter 2, first, move the limit plate 9 so that the opening of the cover plate 8 is not blocked. Subsequently, rotate the rotating member 5 so that the rotating member 3 drives the bladder filter 2 to move from the second position to the first position. During this process, the liquid outlet end 22 of the bladder filter 2 is taken out of the first limiting groove 71 and the second limiting groove 72. Finally, pull out the liquid inlet end 21 of the bladder filter 2 from the mounting hole 53 of the rotating member 5 to complete the disassembly of the bladder filter 2.

[0075] When the filtration of the liquid is no longer required, it can be achieved by closing the liquid inlet joint 6, so that the liquid to be filtered no longer flows into the bladder filter 2; it can also be achieved by quickly disassembling the bladder filter 2, so that the liquid inlet hole 54 of the rotating member 2 is no longer in communication with the liquid inlet joint 6, and the liquid to be filtered no longer flows into the bladder filter 2.

[0076] In summary, a bladder filter installation fixture provided by the present invention, by relatively arranging a first clamping unit and a second clamping unit on the bottom plate. When the first engaging component of the first clamping unit is in the first position, it is convenient to clamp the liquid inlet end of the bladder filter; after the liquid inlet end of the bladder filter is connected to the first engaging component, the first engaging component can drive the bladder filter to move from the first position to the second position; when the bladder filter moves to the second position, the liquid outlet end of the bladder filter is engaged with the second engaging component of the second clamping unit to install the bladder filter between the first clamping unit and the second clamping unit, and complete the installation of the bladder filter, which is beneficial to reducing the installation difficulty of the bladder filter and also beneficial to reducing the working intensity of the staff during the installation process of the bladder filter.
