Description

Technical Field

[0001] This utility model mainly relates to the field of water treatment equipment technology, specifically a filter membrane installation structure for wastewater treatment. Background Technology

[0002] In the field of wastewater treatment, membrane filter modules are the core filtration units, and the rationality of their installation structure directly affects filtration efficiency, ease of equipment maintenance, and operational stability. Currently, traditional membrane filter installation methods often employ flange connections or clamp fixation, which have many limitations in practical applications. When using flange connections, multiple bolts are required for fastening. This not only makes the installation and disassembly process cumbersome and consumes a lot of manpower and time, but also, during long-term use, the bolts are prone to loosening due to wastewater corrosion or vibration, leading to a decrease in sealing performance and causing wastewater leakage. At the same time, flange connections require high installation precision. If there are slight deviations in the length of the filter membrane assembly, it is difficult to achieve a fit through structural adjustments, increasing the difficulty of equipment assembly. While clamp-on fixing offers a slight advantage in installation speed, the clamping force is difficult to distribute evenly to the sealing components, easily causing localized seal failure. This instability in sealing performance is particularly pronounced in high-pressure wastewater treatment environments. Furthermore, in existing installation structures, the connection between the filter membrane assembly and external piping lacks effective guidance and protection, making components prone to wear during installation or maintenance, thus affecting the equipment's lifespan. Therefore, there is an urgent need for a filter membrane installation structure that is easy to install, reliably sealed, and highly adaptable to solve the above-mentioned problems in the existing technology. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a filter membrane installation structure for wastewater treatment, achieved through the following technical solution: A filter membrane installation structure for wastewater treatment includes an internally threaded joint fixed to the end of a pressure vessel, a sealing plate movably installed inside the pressure vessel, a connecting pipe fixedly installed at the center of the sealing plate, and a limiting component installed in the internally threaded joint, the limiting component abutting against the side opposite to the sealing plate.

[0004] Furthermore, the limiting component includes: A limiting plug, one end of which is provided with an external thread that mates with an internal threaded connector, and a through hole is provided in the center of the limiting plug, through which the connecting pipe passes and slides. A thrust ring is movably installed between the limiting plug and the sealing plate, with both ends of the thrust ring abutting against the limiting plug and the sealing plate, respectively.

[0005] Furthermore, the outer end of the limiting plug is fixedly mounted with a ring handle via a bracket.

[0006] Furthermore, a groove is provided on the outer periphery of the sealing plate, and a sealing ring is provided in the groove.

[0007] Furthermore, the inner wall of the internal threaded joint is provided with a guide slope at the end away from the pressure vessel, and the guide slope gradually slopes towards the center from the end of the internal threaded joint inward.

[0008] Compared with the prior art, the beneficial effects of this utility model are: 1. This device adopts a threaded joint structure with an internal threaded connector and a limit component, replacing the traditional multi-bolt fastening method of flange connection. The sealing plate can be fixed and disassembled by rotating the limit component, which greatly reduces the manpower and time required for installation and maintenance. The design of the ring handle further improves the ease of operation and reduces the difficulty of operation.

[0009] 2. The sealing ring on the outer periphery of the sealing plate deforms under the force of the limiting component, which can tightly fill the gap between the sealing plate and the inner wall of the pressure vessel. Together with the thrust ring, it can evenly transmit pressure and effectively avoid local sealing failure. At the same time, the stability of the threaded connection reduces the problem of sealing loosening caused by vibration and other factors, which is especially suitable for high-pressure wastewater treatment environments.

[0010] 3. The limiting component can be adjusted axially via the thread, and the position of the sealing plate can be flexibly adjusted according to the length of the filter membrane assembly. This solves the problem that traditional flange connections have high installation accuracy requirements and are difficult to adapt to filter membrane assemblies of different lengths. The guide bevel of the internal threaded joint also reduces the difficulty of alignment during component installation and improves the versatility of the structure. Attached Figure Description

Detailed Implementation The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0013] Example: A filter membrane installation structure for wastewater treatment like Figure 1-3 As shown, a filter membrane installation structure for wastewater treatment includes the following specific components: An internal threaded connector 20 is fixed to the end of the pressure vessel 10. A sealing plate 30 is movably installed inside the pressure vessel 10. A connecting pipe 301 is fixedly installed at the center of the sealing plate 30. The connecting pipe 301 passes through the sealing plate 30 laterally and is fixedly connected to it. A limit component 40 is installed in the internal threaded connector 20. The limit component 40 abuts against the side of the sealing plate 30 opposite to it.

[0014] The working principle described above is as follows: After the reverse osmosis membrane is installed in the pressure vessel 10, the opening of the pressure vessel 10 is sealed by the sealing plate 30. The sealing plate 30 can be adjusted in position within the pressure vessel 10. The connecting pipe 301 passes through the sealing plate 30 to connect the filter membrane assembly with the external pipeline. The internal threaded joint 20 and the limiting component 40 are threaded together. Rotating the limiting component 40 can make it move axially along the internal threaded joint 20, thereby pressing against the sealing plate 30 to achieve the fixation and sealing of the sealing plate 30. The sealing plate 30 is limited by the threaded limiting component 40, which facilitates quick installation and disassembly. The position of the sealing plate 30 can be flexibly adjusted according to the length of the filter membrane assembly, improving the adaptability of the structure. The cooperation between the sealing plate 30 and the pressure vessel 10 can enhance the sealing performance of the vessel and prevent wastewater leakage. The limiting component 40 includes: The limiting plug 401 has an external thread at one end that mates with the internal threaded connector 20, and a through hole 402 is provided in the center of the limiting plug 401. The connecting pipe 301 passes through the through hole 402 and slides with it. A thrust ring 403 is movably installed between the limiting plug 401 and the sealing plate 30. The two ends of the thrust ring 403 abut against the limiting plug 401 and the sealing plate 30, respectively.

[0015] The limiting plug 401 is connected to the internal threaded connector 20 via an external thread and moves axially when rotated. The connecting pipe 301 passes through the through hole 402 and can move synchronously with the sealing plate 30. The thrust ring 403 transmits force between the limiting plug 401 and the sealing plate 30. When the limiting plug 401 is tightened, the thrust ring 403 is squeezed and the force is evenly transmitted to the sealing plate 30, so that the sealing plate 30 fits tightly against the inner wall of the pressure vessel 10, enhancing the sealing effect and reducing the risk of leakage caused by uneven pressure.

[0016] The outer end of the limiting plug 401 is fixedly mounted with an annular handle 50 via a bracket. The annular handle 50 is fixedly connected to the limiting plug 401 via the bracket. When the operator holds the annular handle 50 and applies rotational force, the limiting plug 401 can be rotated within the internal threaded joint 20, thereby realizing the axial movement of the limiting plug 401. The annular handle 50 provides the operator with a convenient point of force application, which is less strenuous than directly rotating the limiting plug 401 and can improve the efficiency of installation and disassembly.

[0017] The sealing plate 30 has a groove 302 on its outer periphery, and a sealing ring 60 is provided in the groove 302. The sealing ring 60 is installed in the groove 302. When the sealing plate 30 is pressed against by the limiting component 40, the sealing ring 60 is deformed by the compression between the sealing plate 30 and the inner wall of the pressure vessel 10, filling the gap between them and preventing wastewater from leaking from the gap under pressure. The groove 302 also fixes the sealing ring 60, preventing it from shifting during installation or use and ensuring the stability of the sealing effect.

[0018] The inner wall of the internal threaded connector 20, at the end furthest from the pressure vessel 10, has a guide slope that gradually slopes inwards towards the center from the end of the internal threaded connector 20. When installing the limiting component 40, the end of the limiting component 40 first contacts the guide slope, which guides the limiting component 40 into the internal threaded connector 20 along the correct axial direction, ensuring smooth alignment between the external thread of the limiting component 40 and the internal thread of the internal threaded connector 20. This facilitates rapid installation, improves installation efficiency, and reduces operational difficulty.

[0019] In explaining this utility model, it should be noted that the terms indicating location are only for ease of description and understanding, and are not intended to limit the installation location of specific technical features. Other possible installation methods are not excluded.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
