Description

Technical Field

[0001] This utility model belongs to the field of reverse osmosis membrane technology, and in particular relates to a tool for disassembling the membrane shell end cap of a reverse osmosis membrane. Background Technology

[0002] In power plant water treatment systems, reverse osmosis membranes are key components for achieving efficient water production. The membrane housings of reverse osmosis membranes are often installed using an embedded method. While this method ensures the system's sealing and stability to a certain extent, it causes significant inconvenience when repairing or replacing reverse osmosis membrane elements.

[0003] Currently, traditional disassembly methods often rely on force, such as using crowbars, hammers, or other tools to forcibly pry or strike the membrane housing end caps. This method is not only difficult to disassemble effectively but also easily leads to serious consequences. On the one hand, for operators, during the forceful disassembly process, the membrane housing end caps may suddenly pop out or fragments may fly, posing a significant risk of personal injury. On the other hand, from the equipment's perspective, forceful operation can cause irreversible damage to the membrane housing, such as cracks and deformation. This not only shortens the membrane housing's service life and increases equipment replacement costs but also leads to system instability, affecting water production efficiency and water quality.

[0004] Furthermore, traditional dismantling methods are extremely inefficient. Due to the difficulty of dismantling, on-site personnel need to spend a lot of time and energy on the operation, which causes the equipment to be shut down for a long time, seriously affecting the normal operation of the power plant's water treatment system and causing huge economic losses.

[0005] Based on this, the present invention provides a novel tool for disassembling the membrane housing end cap of a reverse osmosis membrane to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a disassembly tool for the membrane housing end cap of a reverse osmosis membrane. This disassembly tool can reduce the risk of membrane housing rupture or fragmentation due to uneven stress, thereby improving operational safety. It can also protect the membrane housing, reduce disassembly damage, and extend its service life. In addition, it is easy to operate, and disassembly can be completed simply by turning the handle, which greatly shortens the disassembly time and improves maintenance efficiency.

[0007] This utility model adopts the following technical solution: a tool for disassembling the membrane housing end cap of a reverse osmosis membrane, used for disassembling the membrane housing end cap, comprising:

[0008] A screw, one end of which is fixedly fitted with an external thread for matching the membrane housing end cap, and the other end is fitted with a nut.

[0009] A rotating handle, which is fixedly installed on the outer wall surface of the nut component;

[0010] A support plate, wherein a through hole is provided in the center of the support plate, and one end of the screw with the external thread can pass through the through hole;

[0011] Multiple buffer columns are installed on the support plate near the membrane shell end cap.

[0012] Furthermore, the external thread is welded to one end of the screw.

[0013] Furthermore, the rotating handle is welded to the nut component.

[0014] Furthermore, there are two rotating handles, which are symmetrically and vertically fixed to the outer wall of the nut component, and are aligned in a straight line.

[0015] Furthermore, the rotary handle includes a handle body and an outer layer covering the outside of the handle body, the inner wall of the outer layer being wavy.

[0016] Furthermore, the outer layer is made of rubber or plastic.

[0017] Furthermore, the support plate is a steel plate.

[0018] Furthermore, the surface of the steel plate away from the membrane head has several raised structures.

[0019] Furthermore, the buffer column is made of polyurethane rubber and has a hollow internal structure.

[0020] Furthermore, the support plate has several mounting holes on the side near the membrane shell end cap. The fixed end of the buffer column is inserted into the mounting holes, and the buffer column and the support plate are fixedly connected by glue or threaded connection.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] In this invention, the disassembly tool is first fixed to the reverse osmosis membrane housing by fixing the support plate, so that multiple buffer columns on one side of the support plate contact the membrane housing. The buffer columns prevent direct rigid collision between the support plate and the membrane housing. Through pressure buffering and their own deformation, they reduce the risk of membrane housing rupture or fragmentation due to uneven stress, improving operational safety. They also compensate for membrane housing dimensional deviations and surface unevenness, enhancing the tool's versatility and applicability. Furthermore, they protect the membrane housing, reduce disassembly damage, extend its service life, and lower equipment replacement costs.

[0023] Subsequently, the external thread of one end of the screw, matching the internal thread of the diaphragm head, is screwed in to initially fix the tool to the diaphragm head, providing a stable point of leverage for subsequent disassembly. Next, the maintenance personnel turn the rotary handle, converting manual labor into rotational power for the screw. The through hole in the center of the support plate acts as a guide and constraint, causing the screw to rotate in a linear motion along the axial direction, smoothly converting rotational motion into linear propulsion force, thus smoothly disassembling the diaphragm head. The entire operation is simple; disassembly can be completed simply by turning the rotary handle, requiring no complex skills or large amounts of manpower, significantly shortening disassembly time and improving maintenance efficiency. Furthermore, this disassembly and cleaning tool has a simple structure, is lightweight, and is easy to carry. Attached Figure Description

[0030] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] The following is in conjunction with the appendix Figure 1 To be continued Figure 4 The present invention will be described in detail with reference to specific embodiments:

[0032] like Figure 1-4 As shown, this utility model provides a disassembly tool for reverse osmosis membrane housing end caps, used for disassembling the membrane housing end caps, comprising:

[0033] Screw 1, one end of which is fixedly installed with an external thread 2 for matching the membrane housing end cap, and the other end is fitted with a nut 6;

[0034] Rotary handle 3, which is fixedly installed on the outer wall of the nut 6;

[0035] The support plate 4 has a through hole 40 in the center. The end of the screw 1 with the external thread 2 can pass through the through hole 40. That is, the diameter of the through hole 40 is preferably large enough to pass through the end of the screw 1 with the external thread 2, so as to facilitate the pulling out of the membrane shell end cap.

[0036] Multiple buffer columns 5 are installed on the support plate 4 near the membrane shell end cap.

[0037] In this invention, the disassembly tool is used by first fixing the support plate 4 onto the reverse osmosis membrane housing, so that multiple buffer columns 5 on one side of the support plate 4 contact the membrane housing. The buffer columns 5 prevent direct rigid collision between the support plate 4 and the membrane housing. Through pressure buffering and their own deformation, they reduce the risk of membrane housing rupture or fragmentation due to uneven stress, improving operational safety. They also compensate for membrane housing dimensional deviations and surface unevenness, enhancing the tool's versatility and applicability. Furthermore, they protect the membrane housing, reduce disassembly damage, extend its service life, and lower equipment replacement costs.

[0038] Subsequently, the external thread 2, matching the internal thread of the diaphragm head, is screwed into one end of the screw 1, completing the initial fixation of the tool to the diaphragm head and providing a stable point of force for subsequent disassembly. Next, the maintenance personnel rotate the handle 3, converting manual labor into rotational power for the screw 1. The through hole 40 in the center of the support plate 4 acts as a guide and constraint, causing the screw 1 to rotate in a linear motion along the axial direction, smoothly converting the rotational motion into linear propulsion force, thereby smoothly disassembling the diaphragm head. The entire operation is simple; disassembly can be completed simply by rotating the handle 3, requiring no complex skills or large amounts of manpower, significantly shortening disassembly time and improving maintenance efficiency. Furthermore, this disassembly and cleaning tool has a simple structure, is lightweight, and easy to carry.

[0039] Furthermore, the external thread 2 is welded to one end of the screw 1; the rotating handle 3 is welded to the nut 6. Compared to other connection methods, such as threaded or snap-fit ​​connections, welding creates a permanent metal bond, greatly enhancing the connection strength between the external thread 2 and the screw 1, and between the rotating handle 3 and the nut 6. During the disassembly of the membrane housing end cap, the external thread 2 needs to withstand significant tensile and torque forces. The welded connection ensures that the external thread 2 will not easily loosen or fall off, guaranteeing smooth disassembly and improving the reliability and durability of the tool.

[0040] Furthermore, there are two rotating handles 3, which are symmetrically and vertically fixed to the outer wall of the nut 6, and are aligned in a straight line. This symmetrical and aligned design allows the user to apply force more effectively with both hands during operation. According to the lever principle, equal lever arms result in a more even application of force, effectively reducing the force required during operation and preventing tool damage or operational errors due to uneven force application. Simultaneously, both hands can apply force to rotate the rotating handles 3, increasing the rotational torque and accelerating the rotation speed of the nut 6. In scenarios requiring frequent operation of the nut 6 to install or disassemble equipment components, this significantly shortens operation time and improves work efficiency.

[0041] Specifically, the rotating handle 3 includes a handle body 30 and an outer layer 31 covering the outside of the handle body 30. The middle of the inner wall of the outer layer 31 has an alternating concave and convex surface in a wavy shape. In this embodiment, the outer layer 31 is made of rubber or plastic and is coated onto the surface of the handle body 30 through injection molding to form an injection-molded outer rubber structure. The wavy inner wall of the outer layer 31 of the rotating handle 3 conforms to the curve of the palm, combined with a hand-shaped ergonomic design, providing a comfortable grip and reducing fatigue even after prolonged use. Furthermore, the outer layer 31, made of rubber or plastic, has strong environmental adaptability. In winter, it can block low temperatures and prevent cold hands; in summer, it has good anti-slip properties, solving the problem of slippery hands due to sweat and ensuring safe operation. Moreover, the outer layer 31 provides insulation and heat insulation, preventing both static electricity and burns from high temperatures, ensuring comprehensive safety during use.

[0042] Furthermore, the support plate 4 is a steel plate of moderate thickness. Steel plates are readily available, and the steel plate is processed into a circular plate with an outer diameter identical to that of the reverse osmosis membrane housing. Several raised structures 40 are formed on the surface of the steel plate away from the membrane housing end cap, which increases the gripping friction when the support plate 4 is moved.

[0043] Furthermore, the buffer column 5 is made of polyurethane rubber and has a hollow internal structure. As a buffer component between the support plate 4 and the membrane shell, the buffer column 5, due to its hollow internal structure, can elastically deform under pressure, acting like a spring to absorb and disperse the pressure transmitted from the support plate 4. Simultaneously, the polyurethane rubber material has good elasticity and flexibility, better adapting to the shape of the membrane shell surface. Even if the membrane shell surface has some unevenness, it can still maintain close contact and evenly distribute pressure, ensuring a smooth disassembly process.

[0044] Specifically, the support plate 4 has several mounting holes 41 near the membrane housing end cap. The fixed end of the buffer column 5 is inserted into the mounting holes 41, and the buffer column 5 and the support plate 4 are fixedly connected by glue or threaded connection to increase the connection strength. The glue can fill the tiny gap between the fixed end of the buffer column 5 and the mounting hole 41, so that the two are tightly bonded. During equipment operation, it can effectively prevent the buffer column 5 from loosening due to vibration and other reasons, ensuring that the buffer column 5 can continuously and stably play a buffering role. At the same time, through the interlocking of the threads, a strong mechanical connection force can be formed between the buffer column 5 and the support plate 4, which can withstand greater tensile and torsional forces, ensuring that the buffer column 5 can be firmly fixed on the support plate 4 under various complex working conditions.

[0045] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
