Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for purification equipment, and more specifically, to a reverse osmosis membrane installer. Background Technology

[0002] During the assembly and maintenance of large-scale reverse osmosis water purification equipment, the reverse osmosis membrane (RO membrane) needs to be installed into the corresponding membrane housing. Because the gap between the reverse osmosis membrane and the membrane housing is small, and the membrane housing usually has O-rings to ensure sealing performance, the reverse osmosis membrane faces significant resistance during installation, making it difficult to push into the membrane housing smoothly.

[0003] Currently, during reverse osmosis membrane installation, workers often manually tap the membrane to force it into the membrane housing. This installation method has several drawbacks: Firstly, the tapping force is difficult to control, easily leading to membrane damage and structural deformation, which in turn affects the subsequent water purification effect, or even renders the membrane unusable, increasing equipment maintenance costs. Secondly, manual operation cannot achieve precise positioning of the reverse osmosis membrane, easily resulting in installation deviations between the membrane and the housing, leading to sealing failure or uneven stress on the membrane, shortening the membrane's lifespan. Furthermore, tapping installation is inefficient, especially in batch installations or large equipment maintenance scenarios, making it difficult to meet operational schedule requirements.

[0025] The following is combined Figures 1-5 The following describes some embodiments of the present invention in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] This utility model provides a reverse osmosis membrane installer, such as... Figure 1 As shown, it includes a positioning cylinder 1, a connector 2, and a pushing assembly; the connector 2 is disposed at one end of the positioning cylinder 1, and the pushing assembly is disposed at the other end of the positioning cylinder 1; the pushing assembly is provided with an installation port, which allows the reverse osmosis membrane to pass through and be placed in the positioning cylinder 1, and the pushing assembly is used to push the reverse osmosis membrane in the positioning cylinder 1.

[0027] In this embodiment, the positioning cylinder 1 is a hollow cylindrical structure, which is the core carrier for accommodating the reverse osmosis membrane. Its internal space can adapt to the shape of common reverse osmosis membranes, ensuring that the membrane can move along the axial direction after being placed. The connecting piece 2 is cylindrical and fixedly installed at one end of the positioning cylinder 1. One end of the connecting piece 2 is fixedly connected to the end of the positioning cylinder 1, such as by welding or threaded connection, and the other end is reserved with an interface structure for docking with the membrane shell. The pushing component is set at the other end of the positioning cylinder 1 away from the connecting piece 2, forming a detachable or fixed connection with the positioning cylinder 1. The installation port on the pushing component is an open structure, and its size must be larger than the outer diameter of the reverse osmosis membrane to ensure that the membrane can smoothly enter the interior of the positioning cylinder 1 through the opening. The pushing component is equipped with a movable force-applying component for directly contacting the membrane and applying thrust.

[0028] Specifically, in this embodiment, the positioning cylinder 1 can position and constrain the reverse osmosis membrane, preventing the membrane from shifting or tilting during installation and preventing collisions caused by positional deviations when the membrane is docked with the membrane housing; the connecting piece 2 can build a transition channel between the positioning cylinder 1 and the membrane housing, so that the membrane can be accurately aligned with the membrane housing inlet after being moved out of the positioning cylinder 1, avoiding direct collision between the membrane and the membrane housing inlet; the function of the pushing component is divided into two parts: first, to facilitate the placement of the membrane through the installation port, solving the problem that the membrane is difficult to put into narrow spaces in the traditional method; second, to apply a stable pushing force to the membrane through the force application component, replacing manual knocking and avoiding damage to the membrane due to excessive instantaneous impact force.

[0029] In use, first align the end of connector 2 furthest from positioning cylinder 1 with the membrane housing to be installed, ensuring that their axes coincide. Then, open the installation port on the push assembly, and slowly insert the reverse osmosis membrane into the positioning cylinder 1 through the installation port with one end facing connector 2. Adjust the position of the membrane body so that the membrane axis is consistent with the axis of positioning cylinder 1. Finally, operate the force-applying component of the push assembly to apply a thrust towards connector 2, pushing the membrane body along the inside of positioning cylinder 1 until the membrane body completely passes through connector 2 and enters the membrane housing. After installation, reverse the operation of the push assembly to separate it from the membrane body, then disconnect connector 2 from the membrane housing and remove the installer.

[0030] In a preferred embodiment, the inner diameter of the positioning cylinder 1 is larger than the inner diameter of the connecting member 2, and a conical surface 10 is formed inside the connection between the positioning cylinder 1 and the connecting member 2.

[0031] In this embodiment, the inner diameter of the positioning cylinder 1 is designed to be larger than that of the connector 2, and a smooth connection is achieved at their joint via an internal conical surface 10. The large end of the conical surface 10 is fixedly connected to the inner wall of the positioning cylinder 1, and the small end of the conical surface 10 is fixedly connected to the inner wall of the connector 2, forming a continuous channel structure of large inner diameter - gradual inner diameter - small inner diameter. The extension direction of the conical surface 10 is consistent with the axis of the positioning cylinder 1 and the connector 2, ensuring that the membrane movement path is always along the axial direction, and the inner wall of the conical surface 10 must remain smooth, without burrs or protrusions, to avoid scratching the membrane.

[0032] Specifically, in this embodiment, the cone surface 10 enables a gradual transition in the inner diameter during the membrane movement process.

[0033] The inner diameter of the positioning cylinder 1 needs to be larger than the outer diameter of the reverse osmosis membrane so that the reverse osmosis membrane can be easily placed into the positioning cylinder 1. The inner diameter of the connector 2 is the same as or slightly smaller than that of the membrane shell so that the reverse osmosis membrane can be easily placed into the membrane shell.

[0034] Because the inner diameter of the positioning cylinder 1 is larger than that of the connector 2, the membrane does not need to be precisely aligned with the smaller-diameter connector 2 when placed inside the positioning cylinder 1, reducing the difficulty of membrane placement. The conical surface 10 guides the membrane to gradually converge towards the center during movement, smoothly entering the smaller-diameter connector 2, preventing jamming or collision between the membrane edge and the connection points of the positioning cylinder 1 and connector 2. Simultaneously, the conical surface 10 also disperses the contact stress between the membrane and the inner wall of the channel, reducing frictional damage to the membrane edge and further protecting the integrity of the membrane.

[0035] In use, after the membrane body is placed into the positioning cylinder 1 through the installation port of the pushing component, the pushing component is operated to apply a thrust. The membrane body first moves along the axis within the positioning cylinder 1. When the front end of the membrane body contacts the conical surface 10, under the action of the thrust, the edge of the front end of the membrane body will gradually move towards the center along the inclined direction of the conical surface 10. As the thrust continues to be applied, the entire membrane body smoothly slides into the connector 2 along the conical surface 10, and finally enters the membrane shell through the connector 2. Throughout the process, there is no need to manually adjust the position of the membrane body; the conical surface 10 will automatically guide the membrane body to align with the connector 2, reducing the difficulty of operation and avoiding jamming or collision.

[0036] In a preferred embodiment, the outer contour of the cross-section of the conical surface 10 is a straight line or a curve.

[0037] In this embodiment, the outer contour of the conical surface 10 can be set to two specific shapes when viewed from the axial section of the conical surface 10, that is, from the cutting plane along the axis of the positioning cylinder 1: The first type is the straight line type, in which the conical surface 10 in the cross section is an inclined straight line segment. One end of the straight line is connected to the cross section line of the inner wall of the positioning cylinder 1, and the other end is connected to the cross section line of the inner wall of the connector 2, forming a triangular right trapezoidal transition area.

[0038] The second type is the curved type, in which the conical surface 10 in the cross section presents a smooth curved segment (such as a circular arc or parabola). One end of the curve is tangentially connected to the cross section line of the inner wall of the positioning cylinder 1, and the other end is tangentially connected to the cross section line of the inner wall of the connector 2, forming an arc-shaped transition area without sharp edges.

[0039] In both configurations, the inner wall of the conical surface 10 must remain smooth to ensure smooth contact of the membrane.

[0040] In this embodiment, the straight conical surface 10 has a simple structure and is easy to manufacture. The inclined straight line provides a clear guiding path for the membrane, making it suitable for scenarios where the membrane has a regular shape and high rigidity, and can quickly guide the membrane into the connector 2. The curved conical surface 10 can better fit the shape of the membrane, especially for membranes with slightly curved edges or flexible materials, reducing local stress concentration between the membrane edge and the conical surface 10, and avoiding damage to the membrane edge due to rigid contact. It is suitable for scenarios where the membrane material is softer and the shape is curved. Both forms can achieve a smooth transition and are compatible with different types of reverse osmosis membranes.

[0041] In a preferred embodiment, the pushing assembly includes a rotating disk 5, a push plate 3, a fixed plate 4, a threaded rod 6, and multiple connecting rods 7; one end of the connecting rod 7 is connected to one end of the positioning cylinder 1, and the other end of the connecting rod 7 is connected to the fixed plate 4; the push plate 3 is disposed on the side of the fixed plate 4 close to the fixed plate 4, and the threaded rod 6 is disposed on the push plate 3, passing through the fixed plate 4; the rotating disk 5 is rotatably disposed on the side of the fixed plate 4 away from the push plate 3, and the rotating disk 5 is threadedly connected to the threaded rod 6, so that the rotation of the rotating disk 5 can drive the push plate 3 to move axially.

[0042] In this embodiment, one end of each of the multiple connecting rods 7 is fixedly connected to the end of the positioning cylinder 1 away from the connecting member 2, such as by welding or bolting, and the other end is fixedly connected to the fixing plate 4. The multiple connecting rods 7 are evenly distributed along the circumference of the positioning cylinder 1, forming a stable support for the fixing plate 4. The fixing plate 4 has a flat plate structure with a through hole in the center for the threaded rod 6 to pass through. The inner wall of the through hole is smooth to ensure that the threaded rod 6 can move freely. The push plate 3 is circular or has a shape that matches the inner wall of the positioning cylinder 1, and is fixedly installed on the side of the fixing plate 4 near the positioning cylinder 1. The center of plate 3 is fixedly connected to one end of threaded rod 6, such as by welding or threaded connection; the axis of threaded rod 6 coincides with the axis of positioning cylinder 1, and the other end of threaded rod 6 passes through the through hole of fixed plate 4 and extends to the side of fixed plate 4 away from push plate 3; the rotating disk 5 has a disc-shaped structure with an internal threaded hole in the center that matches threaded rod 6. The rotating disk 5 is threadedly connected to threaded rod 6 through the internal threaded hole, and the rotating disk 5 can rotate around its own axis and is mounted on fixed plate 4, such as by connecting to fixed plate 4 through bearings, to ensure that the position of fixed plate 4 is fixed when rotating disk 5 rotates.

[0043] Specifically, in this embodiment, the connecting rod 7 is used to connect the positioning cylinder 1 and the fixing plate 4 to form a support frame for the pushing assembly, preventing the fixing plate 4 from shifting under force; the fixing plate 4 can limit the movement direction of the threaded rod 6, ensuring that the threaded rod 6 always moves along the axis of the positioning cylinder 1, preventing the thrust from shifting, and at the same time providing support for the threaded rod 6, the push plate 3, and the rotating disk 5; the function of the push plate 3 is to increase the contact area with the membrane, uniformly transmitting the thrust of the threaded rod 6 to the surface of the membrane, preventing excessive local stress on the membrane; the function of the threaded rod 6 is to transmit power, converting the rotational motion of the rotating disk 5 into axial linear motion; the function of the rotating disk 5 is to provide an operating end, making it convenient for the operator to apply rotational force and reducing the intensity of operation.

[0044] Specifically, in this embodiment, the rotating disk 5 and the fixed plate 4 have an axial positioning structure, which allows the rotating disk 5 and the fixed plate 4 to rotate relative to each other but not to move relative to each other axially, thereby ensuring that the rotating disk 5 can apply force to the push plate 3 when it rotates.

[0045] The axial positioning structure includes a rotating block mounted on the rotary table 5, and a limiting groove and a limiting baffle mounted on the fixed plate 4. The through hole on the fixed plate 4 is coaxially positioned within the limiting groove, and the rotating block is positioned within the limiting groove. Its outer edge is blocked by the limiting baffle to prevent it from disengaging from the limiting groove, thus achieving axial positioning of the rotating block. The rotary table 5 is connected to the rotating block via a rotating rod. The rotating block or rotating rod has a threaded hole that can cooperate with the threaded rod 6.

[0046] In a preferred embodiment, the outer diameter of the push plate 3 is smaller than the inner diameter of the positioning cylinder 1.

[0047] In this embodiment, the outer diameter of the push plate 3 is smaller than the inner diameter of the positioning cylinder 1, forming an annular gap between them. The width of the gap is within a reasonable range, ensuring that the push plate 3 can stably push the membrane while preventing the push plate 3 from contacting the inner wall of the positioning cylinder 1. The gap should not be too large to avoid uneven pushing force caused by the push plate 3 shifting, nor should it be too small to avoid jamming. The outer circumferential surface of the push plate 3 must be flat and smooth, without protrusions or burrs, and the inner circumferential surface of the positioning cylinder 1 must also be smooth to ensure that the gap between them is uniform and that the push plate 3 will not rub or interfere with the inner wall of the positioning cylinder 1 when it moves.

[0048] Specifically, in this embodiment, a groove can be provided on the outer peripheral surface of the push plate 3, and a flexible sealing ring (such as a rubber ring) can be embedded in the groove. The outer diameter of the sealing ring is slightly smaller than the inner diameter of the positioning cylinder 1. This can not only further ensure the coaxiality of the push plate 3 through the sealing ring, but also avoid rigid contact. At the same time, the sealing ring can clean the inner wall of the positioning cylinder 1 and remove impurities. In addition, multiple small guide wheels can be evenly arranged on the outer peripheral surface of the push plate 3. The guide wheels contact the inner wall of the positioning cylinder 1, converting sliding friction into rolling friction and reducing frictional resistance.

[0049] In a preferred embodiment, the connecting rod 7 includes a fixed connecting rod 12 and a movable connecting rod 11; the two ends of the fixed connecting rod 12 are respectively fixedly connected to the positioning cylinder 1 and the fixing plate 4; the two ends of the movable connecting rod 11 are respectively connected to the positioning cylinder 1 and the fixing plate 4, and at least one end is detachably connected, so that an installation port that allows the reverse osmosis membrane to pass through is formed by disassembling the movable connecting rod 11.

[0050] In this embodiment, the connecting rod 7 is divided into two categories: fixed connecting rod 12 and movable connecting rod 11.

[0051] The fixing rod 12 is a non-removable structure. One end of it is fixedly connected to the end of the positioning cylinder 1 away from the connecting member 2, and the other end is fixedly connected to the fixing plate 4. Specifically, in this embodiment, the end of the positioning cylinder 1 has a connecting through hole, and the fixing plate 4 also has a corresponding connecting through hole. After the two ends of the fixing rod 12 pass through the two connecting through holes, they are fixed by nuts. There are at least two fixing rods 12, which are evenly distributed around the circumference of the positioning cylinder 1 to form a basic support frame.

[0052] The movable connecting rod 11 is a detachable structure. One end is detachably connected to the positioning cylinder 1, and the other end is detachably connected to the fixed plate 4. Alternatively, one end of the movable connecting rod 11 can be detachably connected, and the other end can be rotatably connected. The key is to facilitate the movement of the movable connecting rod 11 to form the installation port for the reverse osmosis membrane. The number of movable connecting rods 11 matches the number of fixed connecting rods 12, ensuring that the multiple connecting rods 7 are evenly distributed around the circumference of the positioning cylinder 1. Figure 4 and Figure 5 As shown, there are two fixed connecting rods 12 and two movable connecting rods 11. When the movable connecting rod 11 is disassembled, an opening will be formed between the fixed connecting rods 12, which is the installation port that allows the reverse osmosis membrane to pass through.

[0053] In a preferred embodiment, the detachable connection between the movable connecting rod 11 and the positioning cylinder 1 or the fixing plate 4 is a nut fixing connection, a snap-fit ​​connection, or a pin connection.

[0054] There are many ways to detach the movable link 11, such as: Nut-fixed connection: External threads are provided at both ends of the movable connecting rod 11, and corresponding opening slots are provided on the positioning cylinder 1 and the fixing plate 4. The two ends of the movable connecting rod 11 are respectively inserted into the opening slots of the positioning cylinder 1 and the fixing plate 4, and fixed by tightening the nuts. When disassembling, the movable connecting rod 11 can be taken out from the opening slots by loosening the nuts.

[0055] Snap-fit: The end of the movable link 11 is provided with an elastic buckle, and the positioning cylinder 1 or the fixing plate 4 is provided with a corresponding slot. When the end of the movable link 11 is inserted into the slot, the buckle elastically deforms and snaps into the slot to achieve fixation. When disassembling, press the buckle to make it disengage from the slot, and the movable link 11 can be pulled out.

[0056] Pin connection: A pin hole is provided at one end of the movable connecting rod 11, and a corresponding pin hole is provided on the positioning cylinder 1 or the fixing plate 4. After the pin hole at the end of the movable connecting rod 11 is aligned with the pin hole on the positioning cylinder 1 or the fixing plate 4, the pin is inserted into the two pin holes to fix it. When disassembling, the movable connecting rod 11 can be separated by pulling out the pin.

[0057] It is understood that in this embodiment, the detachable connection between the movable link 11 and the positioning cylinder 1 or the fixed plate 4 can be one of the above-mentioned methods, but it is not limited to the above-mentioned methods. It can also be other detachable connection methods, as long as it can achieve the detachable connection between the movable link 11 and the positioning cylinder 1 or the fixed plate 4.

[0058] In a preferred embodiment, the end of the positioning cylinder 1 is provided with a connecting flange 8, and the connecting rod 7 is connected to the positioning cylinder 1 through the connecting flange 8.

[0059] In this embodiment, a connecting flange 8 is fixedly installed at the end of the positioning cylinder 1 away from the connecting member 2. The connecting flange 8 is an annular flat plate structure, and its central hole communicates with the internal channel of the positioning cylinder 1. The outer diameter of the connecting flange 8 is larger than the outer diameter of the positioning cylinder 1. Multiple connecting holes are evenly opened along the circumference of the connecting flange 8, and the number of connecting holes is the same as the number of connecting rods 7. One end of the connecting rod 7 is provided with a connecting structure adapted to the connecting hole, such as an external thread or a bolt hole. The connecting rod 7 is fixedly connected to the connecting hole of the connecting flange 8 through this connecting structure. For example, a bolt passes through the connecting hole to connect with the connecting rod 7, or the connecting rod 7 is screwed into the connecting hole, thereby realizing the indirect connection between the connecting rod 7 and the positioning cylinder 1.

[0060] The connection between the connecting flange 8 and the positioning cylinder 1 is a fixed connection, such as welding, riveting, or integral molding, to ensure structural strength.

[0061] In a preferred embodiment, the end of the connector 2 away from the positioning cylinder 1 is provided with a connection port 9, which is used to connect the membrane shell.

[0062] In this embodiment, a connecting port 9 is integrally formed or fixedly connected to the end of the connector 2 away from the positioning cylinder 1. The connecting port 9 is a cylindrical or annular structure, and its inner diameter is adapted to the outer diameter of the membrane shell to be connected, or its outer diameter is adapted to the inner diameter of the membrane shell, to ensure that the connecting port 9 can be tightly connected to the membrane shell. The length of the connecting port 9 needs to be moderate, so as to ensure the docking depth with the membrane shell and avoid loose docking, and also to avoid being too long and causing redundancy in the overall structure.

[0063] The inner or outer wall of the connection port 9 must be smooth. If the inner diameter is adapted to the outer diameter of the membrane housing, the inner wall must be equipped with a positioning structure, such as an annular protrusion, to ensure that the membrane housing will not shift after insertion. If the outer diameter is adapted to the inner diameter of the membrane housing, the outer wall must be equipped with a positioning structure to ensure that the connection port 9 is stable after insertion into the membrane housing.

[0064] A groove structure can also be provided on the connection port 9 for matching with the membrane housing, such as... Figure 3 As shown.

[0065] In a preferred embodiment, the connection between the connection port 9 and the connector 2 is a snap-fit ​​or elastic connection.

[0066] In this embodiment, there are multiple ways to connect the connector 9 and the connector 2, such as the following: 1. Snap-fit: The end of the connector 2 furthest from the positioning cylinder 1 is provided with an annular groove or elastic buckle, and the end of the connection port 9 near the connector 2 is provided with a corresponding elastic buckle or an annular groove. The buckle is a flexible metal or plastic part, and the size of the groove is adapted to the buckle. When connecting, align the buckle of the connection port 9 with the groove of the connector 2, apply axial force to make the buckle elastically deform and snap into the groove to achieve fixation. When disassembling, apply reverse force or press the buckle to make it disengage from the groove, and the connection port 9 and the connector 2 can be separated. 2. Flexible connection: The connection port 9 is set as an elastic element, with its inner diameter slightly smaller than the outer diameter of the connector 2. After the connector 2 is inserted into the connection port 9, a fixed connection between the connection port 9 and the connector 2 is achieved under the action of elasticity.

[0067] It is understood that in this embodiment, the connection between the connection port 9 and the connector 2 can be one of the two methods mentioned above, but it is not limited to the two methods mentioned above. It can also be other types of connection methods, such as threaded connection, as long as it can achieve a detachable connection between the connection port 9 and the connector 2, and can be adapted to different membrane shells by replacing different connection ports 9.

[0068] The beneficial effects of this utility model are: By replacing the traditional knocking method with a smooth thrust of the component, and in conjunction with the positioning cylinder 1 and the connector 2, the membrane can be effectively prevented from being bumped or damaged during installation, thus ensuring the integrity of the membrane. The positioning cylinder 1 can position and constrain the reverse osmosis membrane, and the component pushes the reverse osmosis membrane axially to ensure that the membrane moves along the axial direction and avoids installation deviation.

[0069] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
