Description

Technical Field

[0001] This utility model relates to the field of filtration membrane technology, and in particular to a high-efficiency filtration membrane device. Background Technology

[0002] A filtration membrane, also known as a microporous filtration membrane, is used in the production of raw materials, pharmaceutical solvents, water for injection, and injections. It includes various types such as mixed fiber microporous filtration membranes. Filtration membranes are classified according to the size of the particles they trap in the raw water. From coarse to fine, membrane pores are classified into microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, and reverse osmosis membranes. Membrane filtration is a solid-liquid separation technology. It filters water through membrane pores, trapping impurities in the water without any chemical changes, making it a simple treatment technology.

[0003] After a period of use, filter membranes easily accumulate dirt on their surface. This dirt buildup reduces their filtration performance and efficiency, necessitating regular cleaning. However, cleaning filter membranes is inconvenient, requiring disassembly and making maintenance difficult.

[0004] Therefore, existing filter membranes have the technical problem that dirt easily adheres to their surface. Summary of the Invention

[0005] This invention provides a high-efficiency filtration membrane device that solves the technical problem that dirt easily adheres to the surface of the filtration membrane in the prior art.

[0006] Some implementation schemes for solving the above-mentioned technical problems include:

[0007] A high-efficiency filtration membrane device includes a housing;

[0008] A filter membrane assembly is disposed within the housing, and the filter membrane assembly filters the medium flowing through the housing;

[0009] and a support, the support supporting the filter membrane assembly;

[0010] The housing includes an inlet and an outlet. The medium enters the housing through the inlet, is filtered by the filter membrane assembly, and is discharged through the outlet. The filter membrane assembly includes a filter section, which is conical in shape. The tip of the filter section faces the inlet, and the filter section is coaxially arranged with the inlet.

[0011] The housing has an extension extending toward the filter section. The extension, the filter section located below the extension, and the housing located below the filter section form a sludge collection tank to accommodate dirt. Dirt adhering to the surface of the filter section enters the sludge collection tank under its own gravity.

[0012] Preferably, the housing includes an upper shell and a lower shell, the upper shell being fixed to the lower shell by bolts, and the extension being disposed on the upper shell.

[0013] Preferably, the extension and the upper shell are integrally formed, and there is a gap between the extension and the filter section to allow dirt to pass through.

[0014] Preferably, the cross-sectional shape of the extension is arc-shaped.

[0015] Preferably, the filter membrane assembly further includes a connecting ring disposed at the lower end of the filter section, the connecting ring being an integral structure with the filter section, and the connecting ring extending between the upper shell and the lower shell.

[0016] Preferably, the support includes a support portion and a fixing portion disposed at the lower end of the support portion, the filter portion is sleeved on the support portion, and the support portion is evenly distributed with through holes for the medium filtered by the filter portion to pass through.

[0017] Preferably, the through holes are fan-shaped and are evenly distributed along the circumference of the support portion, with the width at the lower end of the through holes being greater than the width at the upper end.

[0018] Preferably, the fixing part is provided with a fixing hole, and the lower shell is provided with a fixing post that mates with the fixing hole, and the fixing post and the lower shell are an integral structure.

[0019] Preferably, the lower shell is provided with a lower connecting shoulder, the upper shell is provided with an upper connecting shoulder, both the upper connecting shoulder and the lower connecting shoulder are provided with mounting holes for mounting bolts, and the fixing post is provided on the lower connecting shoulder.

[0020] Preferably, the upper connecting shoulder and the upper shell are integrally formed, and the lower connecting shoulder and the lower shell are integrally formed. The upper connecting shoulder is provided with a sealing ring, and the lower connecting shoulder is provided with a sealing groove that mates with the sealing ring. The lower connecting shoulder is also provided with a receiving groove, which is not connected to the sealing groove. The connecting ring and the fixing part are both located in the receiving groove.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] By arranging the filter section of the membrane assembly in a conical shape, with the tip of the filter section facing the inlet, in practical applications, the medium enters the housing through the inlet and directly washes over the filter section, thereby flushing the dirt adhering to the surface of the filter section into the dirt collection tank, or causing the dirt adhering to the surface of the filter section to accumulate at the lower end of the filter section. Because dirt does not easily adhere to the sides of the filter section, the filter section exhibits excellent filtration performance and higher filtration efficiency.

[0023] In addition, since dirt accumulates at the lower end of the filter section, the filter section does not require frequent cleaning or maintenance, making the filter membrane device easy to maintain.

[0024] By setting up a sludge collection tank to hold dirt, dirt entering the sludge collection tank from the surface of the filter section will not re-adhere to the side wall of the filter section even when the medium inside the housing is turbulent, thereby further making the filter membrane device easier to maintain.

[0036] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0037] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0038] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0039] Reference Figures 1 to 6 As shown, a high-efficiency filtration membrane device includes a housing 1;

[0040] A filter membrane assembly 2 is disposed within the housing 1, and the filter membrane assembly 2 filters the medium flowing through the housing 1;

[0041] and support 3, the support 3 supporting the filter membrane assembly 2;

[0042] The housing 1 includes an inlet 11 and an outlet 12. The medium enters the housing 1 through the inlet 11, is filtered by the filter membrane assembly 2, and is discharged through the outlet 12. The filter membrane assembly 2 includes a filter section 21, which is conical in shape. The tip of the filter section 21 faces the inlet 11, and the filter section 21 is coaxially arranged with the inlet 11.

[0043] The housing 1 is provided with an extension 13 extending toward the filter section 21. The extension 13, the filter section 21 located below the extension 13, and the housing 1 located below the filter section 21 form a dirt accumulation tank 14 for accommodating dirt. The dirt attached to the surface of the filter section 21 enters the dirt accumulation tank 14 under its own gravity.

[0044] Understandably, the medium filtered by the filter unit 21 can be either a gas or a liquid.

[0045] Understandably, the specific structure and working principle of the filter membrane assembly 2 refer to the prior art. Different filter membrane assemblies 2 are usually required for filtering gases or liquids. Therefore, the specific structure of the filter membrane assembly 2 is determined according to the medium being filtered.

[0046] Reference Figures 1 to 6 As shown, in some embodiments, the housing 1 includes an upper housing 15 and a lower housing 16, the upper housing 15 being fixed to the lower housing 16 by bolts, and the extension 13 being disposed on the upper housing 15.

[0047] A sealed cavity is formed between the upper shell 15 and the lower shell 16, and at least a portion of the filter membrane assembly 2 is located within the cavity. Typically, the filter section 21 should be completely located within the cavity to allow the filter section 21 to have a larger filtration area. The filter section 21 can divide the cavity into an upper chamber and a lower chamber, which communicate with each other through the filter section 21. The upper chamber communicates with the inlet 11, and the lower chamber communicates with the outlet 12.

[0048] In some embodiments, the extension 13 and the upper shell 15 are integrally formed, and there is a gap between the extension 13 and the filter section 21 to allow dirt to pass through.

[0049] In some implementations, the cross-sectional shape of the extension 13 is arc-shaped.

[0050] Understandably, the cross-sectional shape of the extension 13 can also be other shapes, as long as a dirt accumulation groove 14 is formed between the extension 13, the filter 21 and the side wall of the upper shell 15.

[0051] Reference Figures 1 to 6 As shown, in some embodiments, the extension 13 may also be welded to the inner wall of the upper shell 15. Alternatively, the extension 13 may also be fixed to the inner wall of the upper shell 15 by fasteners.

[0052] In some embodiments, the filter membrane assembly 2 further includes a connecting ring 22 disposed at the lower end of the filter section 21. The connecting ring 22 and the filter section 21 are integrally formed, and the connecting ring 22 extends between the upper shell 15 and the lower shell 16.

[0053] The connecting ring 22 is used to fix the filter part 21 between the upper shell 15 and the lower shell 16, so that the filter part 21 has the correct position relative to the shell 1.

[0054] In some embodiments, the support 3 includes a support portion 31 and a fixing portion 32 disposed at the lower end of the support portion 31. The filter portion 21 is sleeved on the support portion 31, and the support portion 31 is evenly distributed with through holes 311 for the medium filtered by the filter portion 21 to pass through.

[0055] Reference Figures 1 to 6 As shown, in some embodiments, the through hole 311 is fan-shaped, the through hole 311 is uniformly arranged along the circumference of the support portion 31, and the width of the lower end of the through hole 311 is greater than the width of the upper end of the through hole 311.

[0056] Understandably, the through hole 311 is used to allow the medium to pass through. Therefore, the shape of the through hole 311 is not specifically limited, and other shapes can also be used, such as circles, etc.

[0057] Because the through hole is fan-shaped, even if the filter section 21 undergoes a certain plastic deformation at the through hole 311, the dirt attached to the surface of the filter section 21 can still quickly enter the dirt accumulation tank 14 because the through hole 311 is inclined along the axis of the filter section 21.

[0058] In some embodiments, the fixing part 32 is provided with a fixing hole 321, and the lower shell 16 is provided with a fixing post 161 that cooperates with the fixing hole 321. The fixing post 161 and the lower shell 16 are an integral structure.

[0059] In some embodiments, the fixing part 32 and the supporting part 31 can be an integral structure.

[0060] Reference Figures 1 to 6 As shown, in some embodiments, the lower shell 16 is provided with a lower connecting shoulder 162, the upper shell 15 is provided with an upper connecting shoulder 151, both the upper connecting shoulder 151 and the lower connecting shoulder 162 are provided with mounting holes for mounting bolts, and the fixing post 161 is provided on the lower connecting shoulder 162.

[0061] In some embodiments, the upper connecting shoulder 151 and the upper shell 15 are integrally formed, and the lower connecting shoulder 162 and the lower shell 16 are integrally formed. The upper connecting shoulder 151 is provided with a sealing ring 152, and the lower connecting shoulder 162 is provided with a sealing groove 163 that mates with the sealing ring 152. The lower connecting shoulder 162 is also provided with a receiving groove 164, which is not connected to the sealing groove 163. The connecting ring 22 and the fixing part 32 are both located in the receiving groove 164.

[0062] In some embodiments, there may be multiple fixing posts 161, which are evenly arranged along the circumference of the receiving groove 164.

[0063] In some embodiments, the depth of the receiving groove 164 is equal to the sum of the thicknesses of the fixing part 32 and the connecting ring 22.

[0064] In some embodiments, the height of the fixing post 161 is not greater than the thickness of the fixing part 32 to prevent the upper end of the fixing post 161 from protruding from the fixing part 32, so that there is no protruding part on the upper surface of the fixing part 32, and the connecting ring 22 can better contact the upper surface of the fixing part 32.

[0065] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0066] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.
