Description

Technical Field

[0001] This utility model relates to the field of membrane housing end cap adapter technology, and in particular to a high-pressure resistant membrane housing end cap adapter structure device. Background Technology

[0002] In high-pressure membrane separation systems (such as water treatment equipment like reverse osmosis, nanofiltration, and ultrafiltration, as well as high-pressure fluid filtration systems in the chemical and energy fields), the membrane housing, as a core pressure-bearing component, directly affects the system's operational safety, sealing, and stability through the connection structure between its end cap and adapter.

[0003] First, during assembly, the relative positions of the end cap and adapter lack a precise positioning reference. In existing designs, the adapter is mostly assembled with the end cap by screwing in, connecting with flange bolts, or direct insertion. However, since the mating surfaces of both are mostly smooth cylindrical surfaces or simple planes, circumferential rotational offset or radial eccentricity is prone to occur during assembly. This positioning deviation will lead to uneven stress on sealing components (such as O-rings and metal sealing surfaces). Under high-pressure conditions, excessive pressure on local sealing surfaces can easily cause leakage, while areas with insufficient pressure may experience increased wear due to medium penetration, seriously affecting the reliability of the seal. Moreover, the positioning stability under high-pressure fluid impact is insufficient. When the membrane separation system is running, the fluid pressure will generate axial thrust and circumferential torque on the adapter. Traditional structures lack effective anti-rotation positioning mechanisms, and the adapter is prone to slight rotation or movement relative to the end cap. This relative movement will not only aggravate the friction and wear of the sealing surfaces, leading to seal failure, but may also cause fatigue damage at the connection points due to stress concentration, reducing the overall high-pressure resistance of the structure, and even causing safety accidents such as shell cracking. Therefore, this utility model proposes a high-pressure resistant membrane shell end cap adapter structure to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a high-pressure resistant membrane housing end cap adapter structure, which solves the problem in the prior art of inconvenient anti-rotation positioning of the end cap and adapter.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a high-pressure resistant diaphragm end cap adapter structure device, including an aluminum plate, an installation hole is opened at one end of the aluminum plate, a plug is installed at the middle position of one end of the aluminum plate, a sealing plate is installed at the other end of the aluminum plate, a groove is opened on the outer side of the sealing plate, an installation seat is installed at the middle position of one end of the sealing plate, an adapter body is arranged inside the installation seat, a first sealing ring is arranged on the outer side of one end of the adapter body, a positioning mechanism is arranged inside the installation seat, and a reinforcing mechanism is arranged at one end of the sealing plate; The positioning mechanism includes a positioning hole and a positioning block. The positioning hole is opened at one end inside the mounting base, and the positioning block is disposed inside the positioning hole. One end of the positioning block is connected to one end of the adapter body.

[0006] A further improvement is that the positioning hole and the positioning block are mutually adapted to each other, and the positioning hole and the positioning block form a locking structure.

[0007] A further improvement is that a shallow groove is provided on the outer side of the positioning block, and a polytetrafluoroethylene wear-resistant block is installed inside the shallow groove, with the polytetrafluoroethylene wear-resistant block in contact with the positioning hole.

[0008] A further improvement is that a sealing groove is provided inside the mounting base, and a second sealing ring is provided inside the sealing groove. The second sealing ring is fitted onto the outside of the adapter body, and the sealing groove and the second sealing ring are mutually compatible.

[0009] A further improvement is that the reinforcing mechanism includes an outer reinforcing rib, an inner reinforcing rib, and a connecting reinforcing rib. The outer reinforcing rib is installed on the outer side of one end of the sealing plate, the inner reinforcing rib is installed on the inner side of one end of the sealing plate, and the outer reinforcing rib and the inner reinforcing rib are connected by a connecting reinforcing rib.

[0010] A further improvement is that multiple connecting reinforcing ribs are provided on the inner side of the outer and inner reinforcing ribs, and the multiple connecting reinforcing ribs are distributed in a ring at one end of the sealing plate.

[0011] The beneficial effects of this utility model are as follows: By setting a positioning mechanism inside the mounting base, and utilizing the cooperation between the positioning hole, positioning block, and PTFE wear-resistant block of the positioning mechanism, the end cap and adapter can be positioned to prevent rotation. This ensures precise positioning of the end cap and adapter, avoids assembly misalignment, ensures uniform force on the sealing components, improves sealing performance under high pressure, resists torque generated by fluid impact, prevents relative rotation, reduces wear and stress concentration, enhances high pressure resistance, reduces assembly difficulty, adapts to multiple specifications, and facilitates maintenance. The use of PTFE wear-resistant blocks can significantly reduce frictional damage between positioning components. PTFE wear-resistant blocks have an extremely low coefficient of friction and... Excellent wear resistance reduces direct metal-to-metal contact wear between the adapter and end cap during assembly and operation, especially under high pressure and small relative displacement conditions, preventing sealing surface failure due to friction. By setting a reinforcing mechanism at one end of the sealing plate, the cooperation between the outer reinforcing ribs, inner reinforcing ribs and connecting reinforcing ribs of the reinforcing mechanism can enhance the overall structural strength and rigidity of the sealing plate, reduce deformation under high pressure, prevent leakage due to poor sealing surface fit caused by sealing plate deformation, disperse the pressure on the sealing plate, reduce local stress concentration, extend the service life of the sealing plate, and ensure sealing reliability, giving this diaphragm end cap adapter a certain high pressure resistance.

Detailed Implementation

[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0015] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a high-pressure resistant membrane shell end cap adapter structure device, including an aluminum plate 1. One end of the aluminum plate 1 has a mounting hole 2. A plug 3 is installed at the middle position of one end of the aluminum plate 1. A sealing plate 4 is installed at the other end of the aluminum plate 1. A groove 5 is opened on the outer side of the sealing plate 4. A mounting base 6 is installed at the middle position of one end of the sealing plate 4. An adapter body 7 is arranged inside the mounting base 6. A first sealing ring 8 is arranged on the outer side of one end of the adapter body 7. A positioning mechanism is arranged inside the mounting base 6. A reinforcing mechanism is arranged at one end of the sealing plate 4.

[0016] The positioning mechanism includes a positioning hole 14 and a positioning block 15. The positioning hole 14 is located inside one end of the mounting base 6. The positioning block 15 is disposed inside the positioning hole 14. One end of the positioning block 15 is connected to one end of the adapter body 7. The positioning hole 14 and the positioning block 15 are mutually adapted to each other and form a locking structure. In use, one end of the adapter body 7 is inserted into the mounting base 6, and the positioning block 15 is inserted into the positioning hole 14. This provides anti-rotation positioning for the adapter body 7 during use, accurately positioning the end cap and the adapter, preventing assembly misalignment, ensuring uniform force on the seal, improving sealing performance under high pressure, resisting torque generated by fluid impact, preventing relative rotation, reducing wear and stress concentration, enhancing high pressure resistance, reducing assembly difficulty, adapting to multiple specifications, and facilitating maintenance.

[0017] A shallow groove is provided on the outer side of the positioning block 15, and a polytetrafluoroethylene (PTFE) wear-resistant block 16 is installed inside the shallow groove. The PTFE wear-resistant block 16 is in contact with the positioning hole 14. In use, the use of the PTFE wear-resistant block 16 can significantly reduce frictional damage between positioning components. The PTFE wear-resistant block 16 has an extremely low coefficient of friction and excellent wear resistance, which can reduce direct metal-to-metal contact wear between the positioning surfaces of the adapter and end cap during assembly and operation. Especially under high pressure and small relative displacement conditions, it can prevent the sealing surface from failing due to friction.

[0018] The mounting base 6 has a sealing groove 12 inside, and a second sealing ring 13 is provided inside the sealing groove 12. The second sealing ring 13 is sleeved on the outside of the adapter body 7. The sealing groove 12 and the second sealing ring 13 are mutually compatible. In use, the cooperation of the sealing groove 12 and the second sealing ring 13 makes the sealing effect between the end cover and the adapter body 7 better.

[0019] The reinforcing mechanism includes an outer reinforcing rib 9, an inner reinforcing rib 10, and a connecting reinforcing rib 11. The outer reinforcing rib 9 is installed on the outer side of one end of the sealing plate 4, and the inner reinforcing rib 10 is installed on the inner side of one end of the sealing plate 4. The outer reinforcing rib 9 and the inner reinforcing rib 10 are connected by the connecting reinforcing rib 11. Multiple connecting reinforcing ribs 11 are provided on the inner side of the outer reinforcing rib 9 and the inner reinforcing rib 10. The multiple connecting reinforcing ribs 11 are arranged in a ring at one end of the sealing plate 4. In use, the cooperation between the outer reinforcing rib 9, the inner reinforcing rib 10, and the connecting reinforcing rib 11 can enhance the overall structural strength and rigidity of the sealing plate 4, reduce deformation under high pressure, avoid leakage due to poor sealing surface adhesion caused by deformation of the sealing plate 4, disperse the pressure on the sealing plate 4, reduce local stress concentration, extend the service life of the sealing plate 4, and ensure sealing reliability.

[0020] Working principle: The operator first inserts one end of the adapter body 7 into the mounting base 6, and inserts the positioning block 15 into the positioning hole 14 to prevent the adapter body 7 from rotating during use. The cooperation of the sealing groove 12 and the second sealing ring 13 makes the sealing effect between the end cover and the adapter body 7 better. At the same time, the use of the outer reinforcing rib 9, the inner reinforcing rib 10 and the connecting reinforcing rib 11 can enhance the overall structural strength and rigidity of the sealing plate 4, reduce deformation under high pressure, avoid leakage due to poor sealing surface adhesion caused by deformation of the sealing plate 4, and at the same time disperse the pressure on the sealing plate 4, reduce local stress concentration, extend the service life of the sealing plate 4, and ensure sealing reliability. At this time, the end cover can be installed and used.
