Description

Technical Field

[0001] This utility model relates to the field of microporous membrane filter technology, and in particular to a microporous membrane filter. Background Technology

[0002] In fields with extremely high cleanliness requirements, such as pharmaceuticals, bioengineering, food and beverage, and electronic chemicals, microfiltration technology is a core process for terminal sterilization and particulate matter control. Its performance directly affects the quality, safety, and compliance of the final product. Conventional filter elements mostly use plastic or metal mesh as a single support, which can easily lead to deformation or rupture of the filter membrane when pressure fluctuates or temperature changes. Existing filter elements are mostly integral structures, which require replacement of the entire set after damage. Moreover, the assembly process requires special tools to tighten, making the operation complex and the downtime long.

[0003] Therefore, it is essential to invent a microporous membrane filter. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a microporous membrane filter to solve the issues of poor overall stability, easy membrane damage, and poor filtration effect that still exist in existing microporous membrane filters. A microporous membrane filter includes a support tube, a connector, a fixing buckle, a pressure cap, a media inlet, a filter element support, a filter element, and a media outlet. The connector is fixedly installed at the top of the support tube, and the fixing buckle is installed on the outside of the connector. The pressure cap is flipped and installed on the outside of the connector, and fixed to the outside of the connector by the fixing buckle. The media inlet is fixedly installed above the pressure cap, and the filter element support and filter element are staggered and slidably installed inside the support tube. The media outlet is fixedly installed at the bottom end of the support tube.

[0005] The filter element support includes a support frame, a docking groove, a positioning groove, a self-compensating shell, and a support core. The docking groove is located inside both ends of the support frame, and the positioning groove is a pointed extension of the docking groove outward. The self-compensating shell is fixedly installed on the outer wall of the support frame, and the support core is slidably installed inside the support frame.

[0006] The filter element includes a first pressure frame, a second pressure frame, a stabilizing mesh, positioning protrusions, and a microporous filter membrane. Positioning protrusions are fixedly installed on the outer sides of both the first and second pressure frames, and these positioning protrusions are connected together by bolts. Microporous filter membranes are fixedly installed inside both the first and second pressure frames, and a microporous filter membrane is sandwiched between these microporous filter membranes.

[0007] The filter element support adopts several sets of cylindrical support structures, and the docking groove and the positioning groove are a set of circular grooves. The depth of the docking groove and the positioning groove is 1 / 2 of the thickness of the filter element. The self-compensating shell is a layer of aluminum metal shell, and the support core is a cylindrical sponge pad that can completely fill the internal space of the support frame. When the filter element support is at low temperature, the self-compensating shell shrinks and slides into the inside of the support tube.

[0008] The filter element and the filter element support are staggered in sequence, and the shape of the filter element matches the docking groove and positioning groove inside the filter element support. The stabilizing mesh is made of two layers of stainless steel mesh. The diameter of the microporous filter membrane is larger than the outer diameter of the stabilizing mesh, and the diameter of the microporous filter membrane is smaller than the outer diameter of the first pressure frame and the second pressure frame.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The filter element support of this utility model can more accurately fix the filter element and prevent the filter membrane from shifting or breaking under high pressure or vibration. The pointed extension structure of the positioning groove can prevent the filter element from rotating and ensure the stability of the media flow channel. The support core can dynamically adjust the pressure distribution, buffer the fluid impact, and extend the filter membrane life. The colored jade of the self-compensating shell can prevent the media from flowing around the filter element.

[0011] 2. The filter element of this utility model achieves precision filtration and long-term stable operation through a three-layer composite structure. It adopts a modular design, with precise matching between the positioning protrusions and the recessed structure of the filter element support, ensuring both efficient particle retention and the ability to withstand pressure differentials and adapt to corrosive environments. The synergistic effect of the rigid support of the first and second pressure frames and the elastic support core gives the microporous filter membrane both pressure differential resistance and quick replacement capability.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0018] As attached Figure 1 To be continued Figure 3 As shown.

[0019] This utility model provides a microporous membrane filter, comprising a support tube 1, a connection port 2, a fixing buckle 3, a pressure cap 4, a media inlet 5, a filter element support 6, a filter element 7, and a media outlet 8. The connection port 2 is fixedly installed on the top of the support tube 1, and the fixing buckle 3 is installed on the outside of the connection port 2. The pressure cap 4 is flipped and installed on the outside of the connection port 2, and fixed to the outside of the connection port 2 by the fixing buckle 3. The media inlet 5 is fixedly installed above the pressure cap 4, and the filter element support 6 and the filter element 7 are staggered and slidably installed inside the support tube 1. The media outlet 8 is fixedly installed at the bottom end of the support tube 1.

[0020] The filter element support 6 includes a support frame 61, a docking groove 62, a positioning groove 63, a self-compensating shell 64, and a support core 65. The docking groove 62 is formed inside both ends of the support frame 61, and the positioning groove 63 is a pointed extension of the docking groove 62 outward. The self-compensating shell 64 is fixedly installed on the outer wall of the support frame 61, and the support core 65 is slidably installed inside the support frame 61.

[0021] The filter element 7 includes a first pressure frame 71, a second pressure frame 72, a stabilizing mesh 73, positioning protrusions 74, and a microporous filter membrane 75. Positioning protrusions 74 are fixedly installed on the outer sides of both the first pressure frame 71 and the second pressure frame 72, and the positioning protrusions 74 are connected together by bolts. Microporous filter membranes 75 are fixedly installed inside both the first pressure frame 71 and the second pressure frame 72, and a microporous filter membrane 75 is sandwiched between the microporous filter membranes 75.

[0022] The filter element support 6 adopts several sets of cylindrical support structures, and the docking groove 62 and the positioning groove 63 are a set of circular grooves. The depth of the docking groove 62 and the positioning groove 63 is 1 / 2 of the thickness of the filter element 7.

When the filter element support 6 is in a low temperature state, the self-compensating shell 64 is shrunk and slid into the interior of the support tube 1.

[0023] The filter element 7 and the filter element support 6 are staggered in sequence, and the shape of the filter element 7 matches the internal docking groove 62 and positioning groove 63 of the filter element support 6. The stabilizing mesh 73 is made of two layers of stainless steel mesh. The diameter of the microporous filter membrane 75 is larger than the outer diameter of the stabilizing mesh 73, and the diameter of the microporous filter membrane 75 is smaller than the outer diameter of the first pressure frame 71 and the second pressure frame 72.

[0024] This microporous membrane filter employs multi-stage filtration for efficient separation: the medium is first introduced through a sealed gland 4, then sequentially passes through a composite filter layer consisting of a filter element support 6 and a filter element 7. A stainless steel stabilizing mesh 73 stably supports the microporous membrane 75, which achieves 0.1μm-level precision filtration. Finally, the purified medium is discharged from the bottom outlet 8. The system, through the dynamic sealing of the self-compensating housing 64 and the elastic pressure regulation of the support core 65, maintains stable operation within the pressure range, preventing damage to the microporous membrane 75 due to media impact.
