Description

Technical Field

[0001] This application relates to the field of coalescing filter elements, and more particularly to a coalescing filter element. Background Technology

[0002] Coalescing filter cartridges are made of various composite materials through special processes. They can not only filter out mechanical impurities in the medium, but also separate emulsified water from the medium through demulsification and coalescence, and coalesce it into larger water droplets, so as to further purify the medium.

[0003] In related technologies, a coalescing filter element includes a first frame and a second frame. The first frame and the second frame are provided with a flow guide layer, a first coalescing layer and a second coalescing layer at intervals. Through the flow guide layer and the coalescence of the first coalescing layer and the second coalescing layer, the coalesced oil droplets automatically float to the inner top of the coalescing filter element and flow out from the top opening of the coalescing filter element. Water flows outward through the side wall of the coalescing filter element, thereby achieving the effect of oil and water separation.

[0004] However, in practical applications, the overall structural strength of the coalescing filter element is low, making it difficult to apply to high-pressure conditions, and therefore improvement is needed. Utility Model Content

[0005] In order to improve the overall structural strength of coalescing filter elements, this application provides a coalescing filter element.

[0006] The coalescing filter element provided in this application adopts the following technical solution:

[0007] A coalescing filter element includes a first frame, a flow guiding layer, a first coalescing layer, a second coalescing layer, a support layer, and a second frame connected to each other. The first frame, the flow guiding layer, the first coalescing layer, the second coalescing layer, the support layer, and the second frame are spaced apart from the inside to the outside, and the support layer is pleated.

[0008] By adopting the above technical solution, in practical applications, the support layer supports the flow guiding layer, the first coalescing layer and the second coalescing layer in the second skeleton, so as to improve the overall structural strength of the coalescing filter element. The support layer is pleated to ensure the support strength of the support layer, further improving the overall structural strength of the coalescing filter element, so that the coalescing filter element can be stably applied to high-pressure conditions.

[0009] Preferably, the flow guiding layer, the first coalescing layer, and the second coalescing layer are all pleated.

[0010] By adopting the above technical solution, and by setting pleats in the flow guiding layer, the first coalescing layer, and the second coalescing layer, the structural strength of the flow guiding layer, the first coalescing layer, and the second coalescing layer is ensured, thereby further ensuring the overall structural strength of the coalescing filter element and improving the stability of the connection between the flow guiding layer, the first coalescing layer, and the second coalescing layer.

[0011] Preferably, the coalescing filter element further includes a drainage layer, which is disposed on the outside of the second frame.

[0012] By adopting the above technical solution and setting up a drainage layer, water can be discharged.

[0013] Preferably, the coalescing filter element further includes an end cap, which is disposed at one end of the second frame.

[0014] By adopting the above technical solution and setting an end cap, one end of the coalescing filter element can be sealed, which can also effectively improve the overall bearing capacity of the coalescing filter element and prevent the coalescing filter element from bending and deforming due to pressure impact during operation.

[0015] Preferably, the end cap includes a cap body and a handle, the cap body is disposed on the second frame, and the handle is disposed on the end of the cap body away from the second frame.

[0016] By adopting the above technical solution, and by setting a cover and a handle, the handle allows the staff to apply force to facilitate the picking and putting of the coalescing filter element.

[0017] Preferably, the coalescing filter element further includes a sealing ring disposed between the end cap and the second frame.

[0018] By adopting the above technical solution and setting a sealing ring, the sealing performance between the end cap and the second frame is improved.

[0019] Preferably, the end cap is detachably connected to the second frame, and the sealing ring is embedded in the end cap.

[0020] By adopting the above technical solution, the end cap is detachably connected to the second frame, and the sealing ring is embedded in the end cap, so as to facilitate the installation and removal of the sealing ring, thereby facilitating the replacement of the sealing ring.

[0021] Preferably, the second frame is provided with two limiting posts at one end near the end cap, and the end cap is provided with two limiting grooves spaced apart along its circumference. The limiting groove includes a first limiting segment and a second limiting segment. The first limiting segment is provided along the length direction of the end cap and one end extends to the end of the end cap near the second frame. The second limiting segment is provided at the end of the first limiting segment away from the second frame and is provided along the circumference of the end cap. The limiting posts are limited at the end of the second limiting segment away from the first limiting segment.

[0022] By adopting the above technical solution, and by setting two limiting posts and two limiting grooves, each limiting post and each limiting groove cooperate to achieve a detachable connection between the end cap and the second frame. The structure is simple and the operation is convenient.

[0023] Preferably, the coalescing filter element further includes a sealing sleeve, which is fitted onto the end cap, and the limiting post passes through the sealing sleeve.

[0024] By adopting the above technical solution and setting a sealing sleeve, the sealing performance of one end of the coalescing filter element is further guaranteed.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The support layer supports the flow guiding layer, the first coalescing layer and the second coalescing layer in the second skeleton, thereby improving the overall structural strength of the coalescing filter element. The support layer is also pleated to ensure the support strength of the support layer, further improving the overall structural strength of the coalescing filter element, so that the coalescing filter element can be stably used in high-pressure conditions.

[0027] 2. By setting pleats in the flow guiding layer, the first coalescing layer, and the second coalescing layer, the structural strength of the flow guiding layer, the first coalescing layer, and the second coalescing layer is ensured, further ensuring the overall structural strength of the coalescing filter element, and improving the stability of the connection between the flow guiding layer, the first coalescing layer, and the second coalescing layer;

[0028] 3. By setting two limiting posts and two limiting grooves, each limiting post and each limiting groove cooperate to achieve a detachable connection between the end cap and the second frame. The structure is simple and easy to operate. Attached Figure Description

[0035] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0036] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0037] This application discloses a coalescing filter element.

[0038] Example 1:

[0039] Reference Figure 1 The coalescing filter element includes a first frame 1, a flow guiding layer 2, a first coalescing layer 3, a second coalescing layer 4, a support layer 5, and a second frame 6, and the first frame 1, the flow guiding layer 2, the first coalescing layer 3, the second coalescing layer 4, the support layer 5, and the second frame 6 are fixed together by bonding.

[0040] The cross-sections of the first skeleton 1, the flow guiding layer 2, the first coalescing layer 3, the second coalescing layer 4, the support layer 5, and the second skeleton 6 are all circular and are spaced apart from the inside out. At the same time, the support layer 5 is pleated, that is, the support layer 5 is bent circumferentially to form pleats.

[0041] The first skeleton 1 and the second skeleton 6 are stainless steel spiral welded and punched skeletons, providing a stable installation foundation for the flow guiding layer 2, the first coalescing layer 3, the second coalescing layer 4, and the support layer 5, and facilitating water drainage. The flow guiding layer 2 and the support layer 5 are made of metal wire mesh to ensure their structural strength. The first coalescing layer 3 and the second coalescing layer 4 are both made of fluoropolymer to ensure the coalescing effect.

[0042] In practical applications, since the support layer 5 supports the flow guiding layer 2, the first coalescing layer 3 and the second coalescing layer 4 in the second skeleton 6, the overall structural strength of the coalescing filter element can be improved. Furthermore, the pleated design of the support layer 5 ensures the support strength of the support layer 5, further improving the overall structural strength of the coalescing filter element, enabling the coalescing filter element to be stably used in high-pressure conditions, thereby improving the applicability of the coalescing filter element.

[0043] In some embodiments, the flow guiding layer 2, the first coalescing layer 3, and the second coalescing layer 4 are pleated to ensure the structural strength of each of the flow guiding layer 2, the first coalescing layer 3, and the second coalescing layer 4, thereby further ensuring the overall structural strength of the coalescing filter element and making the bonding contact surface between the flow guiding layer 2, the first coalescing layer 3, and the second coalescing layer 4 larger, so as to improve the stability of the connection between the flow guiding layer 2, the first coalescing layer 3, and the second coalescing layer 4.

[0044] In some embodiments, the coalescing filter element further includes a drainage layer 7, which is bonded and fixed to the outside of the second frame 6. The drainage layer 7 is made of fluorinated nonwoven fabric to facilitate water drainage.

[0045] Reference Figure 2 In some embodiments, the coalescing filter element also includes an end cap 8, which is sleeved and bonded to one end of the second frame 6 to achieve a seal on one end of the coalescing filter element and effectively improve the overall bearing capacity of the coalescing filter element, preventing the coalescing filter element from bending and deforming due to pressure impact during operation.

[0046] In some embodiments, the end cap 8 includes a cap body 81 and a handle 82. The cap body 81 is hollow and open at both ends. The cap body 81 is bonded and fixedly connected to the second frame 6, so that one end of the drainage layer 7 is pressed between the cap body 81 and the second frame 6, thereby improving the stability of the drainage layer 7 installation. The handle 82 is integrally connected to the end of the cap body 81 away from the second frame 6, so that the operator can apply force to facilitate the loading and unloading of the coalescing filter element.

[0047] Reference Figure 3 In some embodiments, the coalescing filter element also includes a sealing ring 9, which is installed between the cover 81 and the second frame 6 to improve the sealing between the end cover 8 and the second frame 6, thereby improving the stability of the coalescing filter element in use.

[0048] The implementation principle of this embodiment is as follows: In practical applications, since the support layer 5 supports the flow guiding layer 2, the first coalescing layer 3 and the second coalescing layer 4 in the second skeleton 6, the overall structural strength of the coalescing filter element can be improved. Furthermore, the support layer 5 is pleated to ensure the support strength of the support layer 5, which further improves the overall structural strength of the coalescing filter element, enabling the coalescing filter element to be stably applied to high-pressure conditions, thereby improving the applicability of the coalescing filter element.

[0049] Example 2:

[0050] Reference Figure 4 In this embodiment, all other structures are the same as in embodiment 1. The difference is that the end cap 8 is detachably connected to the second frame 6, and the sealing ring 9 is embedded in the inner side wall of the cover 81. By removing the cover 81 from the second frame 6, the sealing ring 9 can be installed and removed, so as to replace the aging sealing ring 9.

[0051] In some embodiments, two limiting posts 10 are fixedly connected to one end of the second frame 6 near the cover 81. The two limiting posts 10 are spaced apart circumferentially along the second frame 6. Correspondingly, the cover 81 has two limiting grooves 83 spaced apart circumferentially. Each limiting groove 83 includes a first limiting segment 831 and a second limiting segment 832. The first limiting segment 831 is arranged along the length of the cover 81 and extends one end to the end of the cover 81 near the second frame 6. The second limiting segment 832 is connected to the end of the first limiting segment 831 away from the second frame 6 and is arranged circumferentially along the end cap 8. Each limiting post 10 passes through the drainage layer 7, and the limiting post 10 is slidably limited by the first limiting segment 831 to the end of the second limiting segment 832 away from the first limiting segment 831, thereby achieving a detachable connection between the end cap 8 and the second frame 6. This design is simple in structure and easy to operate, and also ensures the stability of the connection between the end cap 8 and the second frame 6.

[0052] In some embodiments, the coalescing filter element further includes a sealing sleeve 11, which is fitted onto the cover 81, and each limiting post 10 passes through and limits the sealing sleeve 11, thereby ensuring the sealing of one end of the coalescing filter element and limiting the movement of the limiting post 10 in the second limiting groove 83, thereby improving the stability of the connection between the end cover 8 and the second frame 6.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
