Description

Technical Field

[0001] This utility model relates to the field of liquid degassing technology, and in particular to a support mechanism for a degassing membrane and a degassing device based on a membrane structure. Background Technology

[0002] In industrial production and water treatment, removing dissolved gases (such as oxygen and carbon dioxide) from liquids is a common requirement. Therefore, developing efficient degassing devices is crucial for improving production efficiency and product quality.

[0003] Degassing membranes are a widely used separation technology that uses the pressure difference across a membrane to separate dissolved gases from a liquid and allow them to pass through the membrane into the space on the other side. To ensure the efficient and stable operation of a degassing membrane, a reliable support structure is needed to provide physical support and ensure smooth gas passage. This support structure must not only possess sufficient mechanical strength but also have good permeability and sealing properties to prevent gas leakage or liquid seepage. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide a support mechanism for a degassing membrane that provides uniform support and unrestricted liquid flow.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] In a first aspect, a support mechanism for a degassed membrane includes: a support frame, a support body, and a support mesh;

[0007] The support body is disposed within the support frame;

[0008] The support mesh is laid on the top surface of the support frame and the support body, and is used to support the degassing membrane.

[0009] Furthermore, the support body divides the interior of the support frame into multiple interconnected volumetric cavities.

[0010] Furthermore, the support body includes multiple cross-shaped support units connected in sequence;

[0011] A gap is left between the end of the cross-shaped support unit and the inner wall of the support frame.

[0012] Furthermore, the inner edge of the upper surface is recessed downward to form a positioning step surface;

[0013] The mesh is disposed on the positioning step surface.

[0014] Furthermore, the top surface of the support and the positioning step surface are in the same plane.

[0015] Furthermore, the top surface of the mesh and the top surface of the support frame are in the same plane.

[0016] Furthermore, the support mesh includes a frame and mesh panels;

[0017] The wire frame is arranged around the periphery of the wire mesh and is fixedly connected to the wire mesh.

[0018] Furthermore, the mesh sheet has multiple regularly arranged mesh holes.

[0019] Furthermore, the mesh openings are either circular or square.

[0020] Secondly, a degassing device based on a membrane structure is provided, including a support mechanism for the degassing membrane as described in the above technical solution.

[0021] The technical solution provided by this utility model has the following technical effects:

[0022] 1. The support mesh is laid on the top surface of the support frame and support body to support the degassing membrane. This design ensures that the degassing membrane can be evenly stressed during operation, avoiding deformation or damage caused by local stress concentration. At the same time, the regularly arranged array of mesh holes of the support mesh allows gas to pass through smoothly, improving gas separation efficiency. Furthermore, the entire structure has excellent mechanical strength and sealing performance, thereby enhancing the overall reliability and durability of the equipment.

[0023] 2. The support frame is divided into multiple interconnected volumetric cavities. This design significantly increases the gas buffer space, enhances negative pressure capacity, optimizes the gas flow path, allowing for more even gas distribution and discharge, reducing flow resistance, and improving degassing efficiency.

[0036] Example 1

[0037] like Figures 1 to 4 The support mechanism for a degassing membrane in this embodiment includes: a support frame 1, a support body 2, and a support net 3; the support body 2 is disposed inside the support frame 1; the support net 3 is laid on the top surface of the support frame 1 and the support body 2 and is used to support the degassing membrane.

[0038] The support frame 1 is the basic structural component of the entire degassed membrane support mechanism. It is used together with the support body 2 to support the support net 3 and to provide a stable installation platform for the degassed membrane.

[0039] The support frame 1 is typically a frame-like structure, which can be rectangular, circular, or polygonal, depending on the shape of the degassing membrane and the spatial layout of the equipment. Its top edge is flat to facilitate the laying of the support net 3 and ensure a tight fit with the degassing membrane. The edges of the support frame 1 are smooth and flat to avoid damaging the degassing membrane or other components.

[0040] The support frame 1 is typically manufactured by welding or integral molding. If made of metal, different parts may be joined together by precision welding; if made of plastic, it may be molded in one piece using injection molding.

[0041] The support frame 1 should be made of a material with high strength, corrosion resistance, and good machinability. For example, stainless steel (such as SUS304, SUS316), aluminum alloy, or engineering plastics (such as PP, PVC, PVDF, etc.).

[0042] Specifically: Stainless steel offers excellent corrosion resistance and mechanical strength, making it suitable for long-term use in environments containing chemicals or water. Lightweight and easy to process, aluminum alloys are an option, suitable for applications requiring reduced overall weight. For certain environments, especially those requiring high chemical resistance, engineering plastics can be used to manufacture the support frame.

[0043] When the support frame 1 is made of metal, suitable metal sheets or profiles are first cut according to the design drawings. Then, precision welding technology is used to weld the various parts into the required frame structure. The welded areas are then ground to remove burrs and polish the surface. Necessary surface treatments (such as passivation and coating) are also required to enhance corrosion resistance. Finally, rigorous quality inspections are conducted, including dimensional accuracy and strength testing.

[0044] When the support frame 1 is made of plastic, the corresponding injection mold is first designed and manufactured. The selected plastic granules are heated and melted before being injected into the mold. After cooling and solidification, the finished product is removed and inspected for defects. Secondary processing is performed as needed, such as drilling and cutting. A final inspection is then conducted to ensure compliance with design requirements.

[0045] The support body 2 not only provides support for the screen, ensuring that the degassing membrane is subjected to uniform force, but also increases the gas buffer space, thereby improving the overall degassing efficiency. The support body 2 is usually set inside the support frame 1, dividing the interior of the support frame 1 into multiple interconnected volumetric cavities. These volumetric cavities help to evenly distribute and discharge the gas, thus improving the degassing efficiency.

[0046] Support 2 is made of rigid sheet metal, providing sufficient support for the screen and degassing membrane above. Support 2 not only provides overall structural support but also participates in the design of the fluid flow path, thus influencing degassing efficiency. Support 2 is generally made of the same material as support frame 1. However, different materials are acceptable, as long as they provide sufficient support and divide the interior of support frame 1.

[0047] The support mesh 3 not only needs to provide physical support for the degassing membrane to ensure it does not deform or get damaged due to pressure differences during operation, but also needs to ensure that gas can pass through smoothly. The support mesh 3 must be kept highly flat to ensure that the degassing membrane laid on it can be evenly stressed, avoiding damage caused by local stress concentration. The mesh openings 33 of the support mesh 3 should be distributed as evenly as possible to ensure that gas can pass through uniformly.

[0048] To prevent burrs from damaging the degassing membrane or other components, the edges of the support mesh 3 are ground or bound. Additionally, the edges can be designed with mounting holes or slots for easy attachment to the support frame 1.

[0049] In one embodiment, the support 2 includes a plurality of cross-shaped support units 21 connected in sequence; a gap is left between the end of the cross-shaped support unit 21 and the inner wall of the support frame 1.

[0050] The support 2 is composed of multiple cross-shaped support units 21 connected in sequence. These support units not only divide the interior of the support frame 1 into multiple interconnected volume cavities, but also ensure that the gas can flow smoothly through the gap design between the ends of the support frame 1 and the inner wall of the support frame 1.

[0051] Each cross-shaped support unit 21 consists of two perpendicularly intersecting strip-shaped members, forming a cross shape. The center point of the cross-shaped support unit 21 serves as the main support point, while the four ends extend outwards to approach but not contact the inner wall of the support frame 1, leaving a certain gap. Multiple such cross-shaped support units 21 are connected in sequence to form an integral support network 3, dividing the internal space of the support frame 1 into multiple small, interconnected volumetric cavities.

[0052] Through the design of the cross-shaped support unit 21, the inside of the support frame 1 is divided into multiple interconnected volume chambers, which increases the buffer space for gas, helps to improve the negative pressure capacity, and thus improves the degassing efficiency.

[0053] The top surfaces of the support frame 1 and the support body 2 need to be in the same plane. This means that the support mesh 3 can be smoothly laid on the entire structure, ensuring that the degassing membrane is evenly stressed and that gas can pass through smoothly.

[0054] In one embodiment, the upper surface of the inner edge of the support frame 1 is recessed downward to form a positioning step surface 4; the mesh 32 is disposed on the positioning step surface 4. The top surface of the support body 2 and the positioning step surface 4 are in the same plane, and the top surface of the mesh 32 and the top surface of the support frame 1 are in the same plane.

[0055] The inner edge of the support frame 1 is recessed downwards to form a positioning step surface 4, which is used to precisely fix the position of the mesh 32. The height of the positioning step surface 4 is precisely calculated based on the thickness of the mesh 32 to ensure that the two are flush and to avoid stress concentration or damage to the degassing membrane caused by height differences. The positioning step surface 4 not only provides a precise installation position but also improves the stability of the overall structure.

[0056] In one embodiment, the support net 3 includes a frame 31 and a mesh panel 32; the frame 31 is arranged around the periphery of the mesh panel 32 and is fixedly connected to the mesh panel 32.

[0057] The mesh 32 is the central load-bearing component, made of stainless steel, titanium alloy, or high-strength engineering plastic. Its surface features a regularly arranged array of mesh holes 33, ensuring smooth gas passage while providing sufficient mechanical strength to support the degassing membrane. The mesh holes 33 can be circular, square, or polygonal, with the hole size designed according to actual degassing requirements.

[0058] The mesh frame 31 is made of metal profiles (such as stainless steel strips) or engineering plastics and is arranged around the edge of the mesh panel 32. The cross-sectional shape of the mesh frame 31 can be rectangular, U-shaped, or other adaptable structures to enhance overall rigidity and edge sealing.

[0059] The main function of the wire mesh frame 31 is to fix the wire mesh 32 and prevent it from shifting or deforming during use. It provides an installation and positioning structure for the wire mesh 32, making it easy to install the entire support mesh 3 onto the support frame 1.

[0060] The frame 31 and the mesh panel 32 are fixedly connected in the following way:

[0061] Welding: Applicable to metal mesh panels 32 and mesh frames 31;

[0062] Pressing and bonding: suitable for plastic or composite material structures;

[0063] Snap-on assembly: Suitable for applications requiring frequent replacement of the mesh 32, improving maintenance efficiency.

[0064] After connection, the mesh frame 31 and mesh 32 should ensure that the mesh 32 is flat and taut, without wrinkles or looseness.

[0065] Installation steps for the support mechanism of the degassed membrane:

[0066] 1. Place the support frame 1 in the predetermined position and use a level to ensure it is horizontal. If necessary, the support frame 1 can be securely installed on the equipment frame using flanges or other fixing devices.

[0067] 2. Connect multiple cross-shaped support units 21 sequentially and place them inside the support frame 1 to form a stable support network 3. Use precision measuring tools (such as a micrometer or level) to calibrate the top surface of each cross-shaped support unit 21 to ensure that they are completely aligned with the top surface of the support frame 1 and are in the same plane. Ensure that the gap between the support body 2 and the support frame 1 is evenly distributed to ensure smooth gas flow.

[0068] 3. Place the mesh panel 32 on the positioning step surface 4 of the mesh frame 31, ensuring that the mesh panel 32 is flat and without wrinkles. Fix the mesh panel 32 to the mesh frame 31 using welding, pressing, or snap-fit ​​methods to ensure a firm and reliable connection.

[0069] 4. Lay the assembled support net 3 on the top surface of the support frame 1 and the support body 2. Ensure that the top surface of the support net 3 is coplanar with the top surface of the support frame 1 and the support body 2 to avoid stress concentration or damage to the degassing membrane caused by height differences.

[0070] 5. Select a suitable degassing membrane according to design requirements, ensuring its size and thickness meet the requirements. Lay the degassing membrane directly on top of the support net 3, ensuring it adheres tightly and is evenly stressed. Use appropriate clamps or pressure strips to fix the degassing membrane to the edge of the support net 3 to prevent displacement or loosening during operation.
