Description

Technical Field

[0001] This utility model relates to the field of ceramic membrane technology, specifically to a high-porosity silicon carbide ceramic membrane module. Background Technology

[0002] A ceramic membrane module is a separation device that uses porous ceramic materials as the core filtration medium. It integrates ceramic membrane tubes or sheets into a standardized unit structure. These modules are typically made of inorganic materials such as alumina, zirconium oxide, or titanium oxide through high-temperature sintering, and have advantages such as good chemical stability, high temperature resistance, corrosion resistance, high mechanical strength, and long service life.

[0003] Currently, tubular ceramic membrane modules require sealing rings to be fitted on the outer walls of both ends of the internal filter element to seal the gap between the filter element and the inner wall of the membrane housing. Although this structure can basically meet the sealing requirements, it has obvious shortcomings in actual use. Due to the large friction between the sealing rings at both ends and the inner wall of the membrane housing, coupled with the smooth surface of the filter element and the lack of a dedicated extraction structure, it is difficult for personnel to remove the filter element from the housing when replacing or repairing it, which seriously affects maintenance efficiency and operational convenience. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the large frictional force between the sealing rings at both ends and the inner wall of the membrane housing, coupled with the smooth surface of the filter element and the lack of a dedicated extraction structure, making it difficult for personnel to remove the filter element from the housing during replacement or maintenance, severely affecting maintenance efficiency and operational convenience. This invention proposes a high-porosity silicon carbide ceramic membrane module. This module innovatively adopts a frame-type integrated structure, fixing the filter element mechanism within a frame structure with rubber pillars. A handle inside the upper pillar head provides a clear point of force application for the operator, greatly improving the convenience and efficiency of filter element removal and maintenance. Simultaneously, this structure achieves sealing through two sealing rings—one on the outer wall of the upper pillar head and the other at the top of the retaining ring—significantly reducing the frictional contact area between the filter element and the outer wall, thus lowering disassembly resistance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-porosity silicon carbide ceramic membrane module is designed, comprising a shell mechanism and a frame mechanism. The shell mechanism includes a cylindrical body, with a top cover detachably installed on the top of the cylindrical body and a bottom cover detachably installed on the bottom of the cylindrical body. A retaining ring is fixedly installed inside the cylindrical body. A filter element mechanism is fixedly installed inside the frame mechanism. The frame mechanism includes a lower column head, an upper column head, and several rubber columns. The several rubber columns are fixedly installed on the outer wall of the filter element mechanism. A fixing flange is provided on the outer wall of the lower column head. Sealing rings are provided on the outer wall of the upper column head and the top of the retaining ring.

[0006] Furthermore, the top of the upper cover is provided with a feed inlet, the bottom of the lower cover is provided with a concentrate outlet, and one side of the cylinder is provided with a permeate outlet.

[0007] Furthermore, a handle is fixedly installed inside the upper column head.

[0008] Furthermore, a rigid support column is fixedly installed inside the rubber column, and a shape memory alloy column is fixedly installed inside the rigid support column.

[0009] Furthermore, the filter element mechanism includes a support layer, the support layer having a plurality of mounting holes inside, a transition layer being fixedly installed inside the mounting holes, and a separation layer being fixedly installed inside the transition layer.

[0010] Furthermore, the outer wall of the support layer is provided with a zirconium oxide coating.

[0011] Furthermore, the porosity of the support layer, transition layer, and separation layer is all greater than 45%.

[0012] The high-porosity silicon carbide ceramic membrane module proposed in this utility model has the following advantages: By innovatively adopting a frame-type integrated structure, the filter element mechanism is fixed in a frame mechanism with rubber columns, and the handle set inside the upper column head provides the operator with a clear point of force application, which greatly improves the convenience of filter element removal and maintenance efficiency. At the same time, the structure achieves sealing through two sealing rings on the outer wall of the upper column head and the top of the retaining ring, which significantly reduces the frictional contact area between the filter element and the outer wall and reduces disassembly resistance. In addition, the zirconium oxide coating on the outer wall of the filter element mechanism further enhances its mechanical strength, while the rubber columns with shape memory alloy columns embedded inside provide dual protection in terms of impact resistance and deformation recovery. The overall structure significantly improves the reliability and maintainability of the module while ensuring high porosity separation performance. Attached Figure Description

[0019] See Figures 1-4A high-porosity silicon carbide ceramic membrane module includes a housing mechanism 1 and a frame mechanism 2. The housing mechanism 1 includes a cylindrical body 101, with a top cover 102 detachably mounted on the top of the cylindrical body 101 and a bottom cover 104 detachably mounted on the bottom of the cylindrical body 101. A retaining ring 106 is fixedly mounted inside the cylindrical body 101. A filter element mechanism 3 is fixedly mounted inside the frame mechanism 2. The frame mechanism 2 includes a lower column head 201, an upper column head 202, and several rubber columns 203. The rubber columns 203 are fixedly mounted on the outer wall of the filter element mechanism 3. A fixing flange 204 is provided on the outer wall of the lower column head 201. The outer wall of the upper column head 202 and the retaining ring 106 are fixedly mounted on the outer wall of the filter element mechanism 3. Each part is equipped with a sealing ring 4 at the top. The frame mechanism 2 and the filter element mechanism 3 are pressed and fixed inside the cylinder 101 by the upper cover 102. The frame mechanism 2 and the filter element mechanism 3 are fixed between the retaining ring 106 and the upper cover 102 by the retaining ring 106 locking the fixing flange 204. The sealing ring 4 at the top of the retaining ring 106 ensures the sealing between the inner wall of the outer shell mechanism 1 and the lower column head 201. The sealing ring 4 on the outer wall of the upper column head 202 ensures the sealing between the upper column head 202 and the inner wall of the cylinder 101. A handle 205 is fixedly installed inside the upper column head 202, which makes it convenient for personnel to pull out the frame mechanism 2 and the filter element mechanism 3. The top of the upper cover 102 is provided with a feed inlet 103, the bottom of the lower cover 104 is provided with a concentrate outlet 105, and the side of the cylinder 101 is provided with a permeate outlet 107. The filter element mechanism 3 includes a support layer 301. The support layer 301 has several mounting holes 302 inside. A transition layer 303 is fixedly installed inside the mounting holes 302. A separation layer 304 is fixedly installed inside the transition layer 303. The porosity of the support layer 301, the transition layer 303, and the separation layer 304 is all greater than 45%. The outer wall of the support layer 301 is provided with a zirconia coating 305, which enhances the strength of the outer wall of the filter element mechanism 3. A rigid support column 206 is fixedly installed inside the rubber column 203, and a shape memory alloy column 207 is fixedly installed inside the rigid support column 206. The rubber columns 203 prevent the filter element mechanism 3 from being damaged by bumps to a certain extent. The rigid support column 206 ensures that the rubber column 203 has a certain rigidity. The shape memory alloy column 207 ensures that the rubber column 203 and the rigid support column 206 can be restored after deformation.

[0020] This utility model relates to a high-porosity silicon carbide ceramic membrane module. Through an innovative frame-integrated structure, the filter element mechanism 3 is fixed within a frame mechanism 2 with rubber pillars 203. A handle 205 inside the upper pillar head 202 provides a clear point of force application for the operator, greatly improving the convenience of filter element removal and maintenance efficiency. Simultaneously, the structure achieves sealing through two sealing rings 4 on the outer wall of the upper pillar head 202 and the top of the retaining ring 106, significantly reducing the frictional contact area between the filter element and the outer wall, thus lowering disassembly resistance. Furthermore, the zirconium oxide coating 305 on the outer wall of the filter element mechanism 3 further enhances its mechanical strength, while the rubber pillars 203, embedded with shape memory alloy pillars 207, provide dual protection against impacts and deformation recovery. The overall structure ensures high-porosity separation performance while significantly improving the reliability and maintainability of the module.

[0021] Specifically, during filtration, the material enters through the inlet 103 of the top cover 102. Under pressure, the permeate passes through the porous separation layer 304, transition layer 303, and support layer 301 of the filter element mechanism 3, and is finally discharged from the permeate outlet 107 on the side of the cylinder 101. The concentrate flows out through the concentrate outlet 105 at the bottom. When the filter element needs to be replaced or repaired, simply open the top cover 102, and the operator can directly hold the handle 205 inside the upper column head 202 to easily pull the entire frame mechanism 2 together with the filter element mechanism 3 upwards from the cylinder 101 without much friction with the inner wall of the cylinder 101. The disassembly process is labor-saving and efficient.
