Description

Technical Field

[0001] This utility model relates to the field of filtration system technology, and in particular to a stop and filtration device for a capsule filter. Background Technology

[0002] Encapsulated filters, also known as integrated filters, use pleated imported filter membranes with a large filtration surface area, making them suitable for filtering larger volumes of solutions.

[0003] Typically, bladder filters are installed and used in conjunction with manifold assemblies. Because bladder filters usually do not vibrate during filtration, most manifold assemblies connected to the ends of the bladder filter do not have stop structures. Under abnormal circumstances such as insecure installation, abnormal pressure, or abnormal flow, the bladder filter may detach from the manifold assembly.

[0004] Therefore, a new solution is needed to address the aforementioned technical problems. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a stop and a filtration device for a capsule filter, so as to solve the problem of detachment between the capsule filter and the manifold assembly in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a stop for a capsule filter, specifically configured as follows: the stop has a first mounting groove extending through its own thickness direction, and a first limiting part is provided on the inner sidewall of the first mounting groove.

[0007] Optionally, the first limiting part is configured as a boss protruding from the inner sidewall of the first mounting groove, and the boss is provided with a first guide part on the side near and / or away from the outlet direction of the first mounting groove.

[0008] Optionally, the first guide portion is configured as a guide ramp.

[0009] Optionally, the first limiting part is provided on both the left and right sides of the first mounting groove; or the first limiting part is provided on either the left or right side of the first mounting groove.

[0010] Optionally, the stop member is further provided with a second mounting groove connected to the first mounting groove, and the interior of the second mounting groove is provided with a second limiting part.

[0011] Optionally, the second limiting portion is configured as a limiting groove extending outward along the inner sidewall of the second mounting groove, and the limiting groove is configured as an arc-shaped segment.

[0012] Optionally, a second guide portion is provided at the opening of both the first mounting groove and the second mounting groove.

[0013] This utility model also provides a filtration device, which includes a capsule filter and a manifold assembly. The capsule filter includes an outlet cap with a journal. The manifold assembly is used to install the capsule filter and includes a stop member for the capsule filter as described in any of the above claims. A first limiting part is used to limit the journal in the first mounting groove.

[0014] Optionally, the liquid outlet cap further includes a protruding edge connected to the journal, and the protruding edge is provided with a third limiting part in the circumferential direction. When the protruding edge is placed in the second mounting groove, the third limiting part cooperates with the second limiting part to limit the rotation of the capsule filter.

[0015] Optionally, the third limiting portion is configured as a protrusion extending radially along the convex edge, the protrusion extending circumferentially along the convex edge to form an arc-shaped boss.

[0016] As described above, the stop member and filtration device for a capsule filter of this utility model have the following beneficial effects:

[0017] By providing a first limiting part on the inner side wall of the first mounting groove where the stop part mates with the journal of the bladder filter outlet end cap, the first limiting part can prevent the journal from falling out of the first mounting groove when there is a risk of the bladder filter and the manifold assembly falling off. This helps to prevent the journal from falling out of the first mounting groove, and thus helps to prevent the bladder filter and the manifold assembly from falling off. Attached Figure Description

[0032] like Figures 1 to 5As shown, some embodiments of this application provide a stop for a capsule filter. The stop 1 can be used on a manifold assembly 3 that mates with the capsule filter 2. The stop 1 has a first mounting groove 11 for mounting the journal 21 of the capsule filter 2. The first mounting groove 11 extends through the thickness direction of the stop 1, allowing the capsule filter 2 to communicate with the pipe 31 on the manifold assembly 3 after mating. Furthermore, a first limiting portion 12 is provided on the inner wall of the first mounting groove 11. When there is a risk of the capsule filter 2 detaching from the manifold assembly 3, the first limiting portion 12 prevents the journal 21 from detaching from the first mounting groove 11, thus helping to prevent the capsule filter 2 from falling out of the manifold assembly 3.

[0033] It should be noted that, in order for the first limiting part 12 to limit the journal 21, the first limiting part 12 is located above the axis of the journal 21.

[0034] For example, in order to match the journal 21 of the capsule filter 2, the first mounting groove 11 can be configured as including but not limited to a square groove, a U-shaped groove, etc.

[0035] In one example, the first limiting part 12 can be configured in one of two ways within the first mounting groove 11: Firstly, the first limiting part 12 is provided on both the left and right sides of the first mounting groove 11, and the first limiting parts 12 located on the left and right sides of the first mounting groove 11 can be positioned opposite each other or offset; secondly, the first limiting part 12 is provided on either the left or right side of the first mounting groove 11. Both configurations of the first limiting part 12 enable it to limit the movement of the journal 21 of the capsule filter 2.

[0036] For example, one or more first limiting parts 12 can be provided on the left or right side wall of the first mounting groove 11. The number of first limiting parts 12 on the left or right side wall can be one, two, etc., and the specific number can be set according to actual needs. When there are multiple first limiting parts 12 on the left or right side wall of the first mounting groove 11, the distance between two adjacent first limiting parts 12 can be set to be greater than or equal to the diameter of the journal 21 of the capsule filter 2, or it can be set to be less than the diameter of the journal 21 of the capsule filter 2, so as to achieve multiple stops on the journal 21.

[0037] like Figure 1 and Figure 4As shown, in some embodiments, the first limiting part 12 is configured as a boss protruding from the inner sidewall of the first mounting groove 11. To facilitate the installation of the journal 21 of the capsule filter 2, a first guide part 13 may be provided on the side of the boss near the outlet direction of the first mounting groove 11. To facilitate the disassembly of the journal 21 of the capsule filter 2, a first guide part 13 may be provided on the side away from the outlet direction of the first mounting groove 11. Regarding the configuration of the first limiting part 12, the first guide part 13 may be provided only on the side of the boss near the outlet direction of the first mounting groove 11, or only on the side of the boss away from the outlet direction of the first mounting groove 11, or the first guide part 13 may be provided on both sides of the boss near and away from the outlet direction of the first mounting groove 11.

[0038] For example, the first guide portion 13 is configured as a guide ramp. In order to protect the journal 21 of the capsule filter 2 from wear and to reduce the difficulty of installing and disassembling the capsule filter 2, the guide ramp and the top surface of the boss are connected by an arc.

[0039] like Figure 1 , Figure 2 , Figures 6 to 8 As shown, in some embodiments, when a third limiting part 23 is provided on the protruding edge 22, a second mounting groove 14 connected to the first mounting groove 11 is also provided on the stop member 1. The second mounting groove 14 is used to install the protruding edge 22 of the capsule filter 2, and a second limiting part 15 is provided inside the second mounting groove 14. The second limiting part 15 cooperates with the third limiting part 23 to limit the rotation of the capsule filter 2.

[0040] For example, in order to match the protrusion 22 of the capsule filter 2, the second mounting groove 14 can be configured as including but not limited to a square groove, a U-shaped groove, etc.

[0041] In one example, the second limiting part 15 is configured as a limiting groove extending outward along the inner sidewall of the second mounting groove 14. To allow the third limiting part 23 to rotate within the limiting groove following the rotation of the capsule filter 2, the limiting groove is configured as an arc-shaped segment, the length of which is set according to the preset rotation angle of the capsule filter 2. The limiting groove can be located at the bottom of the second mounting groove 14, or it can be configured to extend along the bottom of the second mounting groove 14 towards the left or right side wall. Regardless of the position of the limiting groove, it is necessary to ensure that the third limiting part 23 can cooperate with the limiting groove when installed aligned with the centerline of the second mounting groove 14.

[0042] In some embodiments, in order to facilitate the installation of the capsule filter 2, a second guide portion 16 is provided at the opening of both the first mounting groove 11 and the second mounting groove 14.

[0043] For example, the second guide portion 16 is configured as a guide ramp.

[0044] like Figure 2 As shown, some embodiments of this application also provide a filtration device, including a capsule filter 2 and a manifold assembly 3 that cooperates with the capsule filter 2. The capsule filter 2 includes an outlet cap 24, on which a journal 21 is provided; the manifold assembly 3 includes the aforementioned stop member 1 for the capsule filter 2, and the first limiting portion 12 of the stop member 1 is used to limit the journal 21 in the first mounting groove 11 of the stop member 1, which helps to prevent the capsule filter 2 from falling off the manifold assembly 3.

[0045] like Figures 6 to 8 As shown, in some embodiments, the liquid outlet cap 24 further includes a flange 22 connected to the journal 21, and the flange 22 is provided with a third limiting portion 23 in the circumferential direction. When the flange 22 is placed in the second mounting groove 14 of the stop member 1, the second limiting portion 15 of the stop member 1 cooperates with the third limiting portion 23 on the flange 22 to limit the rotation angle of the capsule filter 2.

[0046] For example, the third limiting part 23 is configured as a protrusion extending radially along the convex edge 22, which extends circumferentially along the convex edge 22 to form an arc-shaped boss. It should be noted that the length of the arc-shaped boss is less than the length of the limiting groove of the stop member 1, so that the arc-shaped boss can move within the limiting groove, thereby limiting the rotation angle of the capsule filter 2.

[0047] In summary, the stop and filtration device for a bladder filter of this application, by providing a first limiting part on the inner side wall of the first mounting groove where the stop mates with the journal of the bladder filter outlet end cap, provides a stop for the journal to detach from the first mounting groove when there is a risk of detachment between the bladder filter and the manifold assembly. This helps to prevent the journal from detaching from the first mounting groove, thereby helping to prevent the bladder filter from detaching from the manifold assembly.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
