Description

Technical Field

[0001] This utility model belongs to the technical field of core filter structure, and in particular relates to a filter element support ring for filter assembly. Background Technology

[0002] Currently, in the field of membrane separation technology, the filter element support ring of membrane housing products has a flush-end structure. This typically lacks lateral sway constraint on the filter element's support position. During installation, one end of the support ring is forced to align with one end of the filter element through compression to achieve support. However, in actual use, it is often impossible to determine whether the support ring is properly installed, and the support status for the filter element is uncertain. Inability to effectively support and secure the filter element can lead to damage to the filter element or its support ring. Utility Model Content

[0003] In view of this, the present invention aims to provide a filter element support ring for filter assemblies to solve the problem of filter element displacement or damage caused by inaccurate positioning and unstable support during installation of existing filter element support rings.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a filter element support ring for a filter assembly, the filter element support ring comprising a support body, a flow channel formed on the support body, the support body being a circular ring structure, a positioning guide structure being provided on the inner wall of the circular ring structure of the support body, a stop platform, a conical locking surface and a guide flange being sequentially provided on the positioning guide structure, the stop platform being a stepped structure, the taper of the conical locking surface gradually narrowing from the guide flange to the stop platform, and the guide flange being an oblique transition structure.

[0005] Furthermore, the number of flow channels is multiple, and the multiple flow channels are evenly distributed along the circumference of the supporting body.

[0006] Furthermore, the number of positioning guide structures is multiple, and the multiple positioning guide structures are evenly distributed along the circumference of the supporting body.

[0007] Furthermore, the positioning and guiding structures are arranged in groups of two, with multiple groups of positioning and guiding structures evenly distributed along the circumference of the supporting body.

[0008] Furthermore, vertical ribs are provided on the outer wall of the supporting body.

[0009] Furthermore, the number of vertical ribs is multiple, and the multiple vertical ribs are evenly distributed along the circumference of the supporting body.

[0010] Furthermore, the positioning guide structure corresponds to the position of the upright rib, and the positioning guide structure and the upright rib are respectively set on the inner and outer sides of the supporting body.

[0011] Furthermore, the vertical ribs are connected to the inner wall of the membrane shell.

[0012] Furthermore, the supporting body, uprights, and positioning guide structure are an integrated structure.

[0013] Furthermore, the stop platform abuts against the end face of the filter element.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model provides a filter element support ring for a filter assembly, which has self-centering and locking capabilities. It possesses positioning and guiding functions, allowing it to stabilize itself within the membrane housing and forming a self-locking force with the filter element through tapered compression. This better stabilizes the filter element when it is impacted. Through its guiding, positioning, and guiding functions, it ensures excellent coaxiality between the filter element and the membrane housing, guaranteeing balanced media flow and sealing in the circumferential direction. This avoids media leakage caused by uneven circumferential compression of the filter element, while ensuring balanced media flow better utilizes the filter element's filtration performance and extends its service life.

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0024] See Figure 1-5 This embodiment describes a filter element support ring for a filter assembly. The filter element support ring 6 includes a support body with a flow channel 1. The support body is a ring-shaped structure, and a positioning guide structure is provided on the inner wall of the ring-shaped structure. The positioning guide structure is provided with a stop platform 3, a tapered locking surface 5, and a guide flange 4 in sequence. The stop platform 3 is a stepped structure, and the taper of the tapered locking surface 5 gradually narrows from the guide flange 4 to the stop platform 3. The guide flange 4 is an oblique transition structure.

[0025] The stop platform 3 is used to receive the end face of the filter element 7, ensuring the positional accuracy of the filter element 7 during installation. The stop platform 3 has a tapered locking surface 5 with a certain slope, which increases the locking force between the filter element support ring 6 and the filter element 7 when the filter element 7 is pressed inward, fixing the filter element 7 and the filter element support ring 6 together and ensuring the stability of the connection between the filter element 7 and the filter element support ring 6. At the end of the filter element 7, there is a guide flange 4 with an oblique transition. During installation, the guide flange 7 can guide and position the filter element 7, preventing skewed installation and ensuring self-centering during installation.

[0026] In this embodiment, there are one or more flow channels 1, which are evenly distributed along the circumference of the support body. This ensures the smooth flow of the medium and reduces the resistance to medium flow.

[0027] The positioning guide structure described in this embodiment is multiple, and the multiple positioning guide structures are evenly distributed along the circumference of the support body. This can ensure the positional accuracy of the filter element 7 during installation, guarantee the stability of the connection between the filter element 7 and the filter element support ring 6, and ensure that the filter element 7 can self-center during installation.

[0028] The positioning guide structure described in this embodiment is arranged in groups of two, with multiple groups of positioning guide structures evenly distributed along the circumference of the support body. This ensures the positional accuracy of the filter element 7 during installation, guarantees the stability of the connection between the filter element 7 and the filter element support ring 6, and ensures that the filter element 7 can self-center during installation.

[0029] In this embodiment, the outer wall of the support body is provided with vertical ribs 2. There are one or more vertical ribs 2, which are evenly distributed along the circumference of the support body. The vertical ribs 2 are connected to the inner wall of the membrane shell, which can ensure the stability of the support ring in the shell.

[0030] The positioning guide structure described in this embodiment corresponds to the position of the upright rib 2, and the positioning guide structure and the upright rib 2 are respectively set on the inner and outer sides of the support body.

[0031] The supporting body, uprights 2, and positioning guide structure described in this embodiment are an integrated structure.

[0032] In this embodiment, the stop platform 3 abuts against the end face of the filter element 7.
