Description

Technical Field

[0001] This invention relates to the field of MBR membrane module maintenance and disassembly equipment technology, and in particular to a disassembly and disassembly system and method for MBR membrane module maintenance. Background Technology

[0002] In membrane bioreactor (MBR) processes, the membrane module is the core filtration unit. After long-term operation, the membrane module needs to be periodically removed from the membrane tank for offline chemical cleaning, integrity testing, or replacement.

[0003] Please see Figure 1 The membrane module structure shown is typically characterized by its large weight, bulky size, and installation within a dense membrane frame, resulting in extremely limited working space.

[0004] Currently, the industry commonly uses hoisting for assembly and disassembly. During hoisting operations, manual control of the overhead crane's lifting and movement is required, along with manual prying and pulling to adjust the membrane module's posture. While this method is usable, the structure and weight of the membrane module itself make adjusting its hoisting posture particularly difficult, and collisions are easily caused during the hoisting process, potentially damaging the membrane module and other structures within the membrane tank. Therefore, we propose a disassembly and assembly system for MBR membrane module maintenance, as described in this application. Summary of the Invention

[0005] To address the aforementioned shortcomings in the existing technology, this invention provides a disassembly and assembly system and method for maintaining MBR membrane modules, thereby solving the problem that due to the structure and weight of the MBR membrane modules themselves, it is difficult to adjust their lifting posture, and they are prone to collisions during the lifting process, which can damage the membrane modules and other structures within the membrane tank.

[0006] To achieve the above objectives, this application provides a disassembly and assembly system for MBR membrane module maintenance, comprising:

[0007] Connector; The main frame is rotatably connected to the connecting platform and can rotate between the vertical and horizontal directions. Guide rails are provided on the main frame along its length. The sliding frame is slidably mounted inside the guide rail and can extend downwards out of the main frame, and follow the rotation of the main frame; A sliding drive component is fixedly connected to the main frame and has a sliding telescopic end that can move along the length of the main frame. The sliding telescopic end is fixedly connected to the sliding frame and is used to drive the sliding frame to move along the guide rail. The rotating module is fixedly connected to the sliding frame and has a driven rotating frame that can rotate along the height direction of the sliding frame; The clamping module is fixedly connected to the driven rotating frame and has two sets of symmetrically arranged clamping ends. The two sets of clamping ends can move in opposite directions. The clamping ends are provided with clamping grooves for clamping the MBR membrane module frame structure.

[0008] The rotating module has a rotating follower at one end facing the main frame. The rotating follower is driven and connected to the driven rotating frame. A driving module is fixed on the main frame. A rotating driving block is provided at one end of the driving module facing the sliding frame. The rotating driving block is connected to the main frame by sliding. The sliding frame has a rotating position and the rotating driving block has a driving position. When the sliding frame is in the rotating position and the rotating driving block is in the driving position, the rotating driving block abuts against the rotating follower to drive the rotating follower to rotate.

[0009] The rotating module includes a support base fixedly connected to the sliding frame. A rotating base is mounted on the support base at one end away from the main frame by rotation. The rotating base is fixedly connected to the driven rotating frame. A rotating shaft is mounted inside the support base by rotation. The central axis of the rotating shaft coincides with the central axis of the rotating base. One end of the rotating shaft passes through the support base and is driven to the rotating base. The other end of the rotating shaft is driven to the rotating driven part.

[0010] The supporting base has a supporting groove at one end facing the rotating base, and a supporting bearing is installed in the supporting groove. The rotating base has a rotating flange at one end facing the supporting base, and the rotating flange is inserted into the inner wall of the supporting bearing. A supporting rotating hole is opened in the supporting groove, penetrating the supporting base, and a rotating shaft is rotatably inserted into the supporting rotating hole. A rotating protrusion is provided at one end facing the supporting base, and a rotating driven groove is opened in the rotating protrusion. One end of the rotating shaft is inserted into the rotating driven groove. A conductive slip ring is fixed in the rotating flange, and the rotor of the conductive slip ring is fixedly connected to the rotating base. A wiring groove is opened at the end of the rotating base facing away from the supporting base, and the wiring groove penetrates the supporting base and extends into the rotating flange. The central axis of the rotating flange, the central axis of the rotating driven groove, and the central axis of the conductive slip ring coincide.

[0011] The rotary driven part includes a rotary housing fixedly connected to a support base. A rotary guide cavity is formed inside the rotary housing along the central axis of the rotary shaft. A transmission clutch block matching the rotary drive block is slidably installed in the rotary guide cavity. A guide groove penetrating the transmission clutch block is formed in the center of the transmission clutch block. The rotary shaft is inserted into the guide groove via a spline connection. A first spring is provided in the rotary guide cavity. The first spring is sleeved on the outer wall of the rotary shaft. One end of the first spring abuts against the transmission clutch block, and the other end abuts against the support base. The elastic force of the first spring pushes the transmission clutch block to move towards the rotary drive block. A driven clutch ring is provided in the rotary guide cavity. The driven clutch ring rotates and engages with the rotary housing and can be driven to connect with the transmission clutch block. When the rotary drive block, the transmission clutch block, and the driven clutch ring are inserted into each other, the rotary drive block is in a driving position.

[0012] The outer wall of the driven clutch ring is provided with multiple clutch flanges, and a locking groove is formed between adjacent clutch flanges. A locking mechanism is fixed on the rotating driven part. The locking mechanism has a locking protrusion that matches the locking groove. The drive module has an abutting active block that moves synchronously with the rotating drive block. The abutting active block is used to drive the movement of the locking protrusion so that the locking protrusion can be inserted into the locking groove.

[0013] The outer wall of the rotating housing is provided with a rotating groove extending into the rotating guide cavity. The locking protrusion is slidably inserted into the rotating groove. A locking guide post is provided at the end of the locking protrusion facing away from the clutch flange. A second spring is fitted on the outer wall of the locking guide post. One end of the second spring abuts against the locking protrusion, and the other end of the second spring abuts against the rotating groove. The elastic force of the second spring pushes the locking protrusion into the locking groove. The end of the locking guide post extends out of the rotating groove and is provided with an extension protrusion. A driving structure is provided in the extension protrusion. The locking mechanism also includes a pushing structure, which is connected to the driving structure. When the abutting active block pushes the pushing structure, the pushing structure drives the locking protrusion to move away from the locking groove.

[0014] The driving structure is a wedge-shaped driven groove set on the extension protrusion. The pushing structure includes a driven guide post. One end of the driven guide post is provided with a driven block that matches the driven block. The other end of the driven guide post is provided with a wedge-shaped driving block that can be inserted into the wedge-shaped driven groove. A third spring is fitted on the outer wall of the driven guide post. One end of the third spring abuts against the driven block, and the other end abuts against the outer wall of the rotating housing. The elastic force of the third spring pushes the driven block to move away from the extension protrusion.

[0015] The drive module includes a drive base fixedly connected to the main frame, a drive sliding frame slidably mounted on the drive base, a drive motor fixedly mounted on the drive sliding frame, a rotary drive block fixedly connected to the output shaft of the drive motor, a plurality of drive protrusions provided on the rotary drive block, and a drive telescopic cylinder fixedly mounted on the drive base, the telescopic end of the drive telescopic cylinder being fixedly connected to the drive sliding frame.

[0016] Multiple rotatable guide wheels are installed on the side walls of the left and right sides of the sliding frame, and the guide wheels are slidably inserted into the guide rail.

[0017] The rotation axis of the main frame is set along the width direction of the main frame. A flip drive is mounted on the connecting platform by rotation. The rotation axis of the flip drive is set along the width direction of the main frame. The flip drive has a retractable flip telescopic end. The flip telescopic end is connected to the main frame by rotation. The rotation axis of the flip telescopic end is set along the width direction of the main frame so that the main frame can rotate and switch between the vertical and horizontal directions.

[0018] The clamping module includes a clamping base fixedly connected to the driven rotating frame, and a clamping end including a clamping sliding frame. The clamping sliding frame is connected to the clamping base along the width direction of the main frame by sliding. A clamping telescopic cylinder is fixed on the clamping base, and the telescopic end of the clamping telescopic cylinder is connected to the clamping sliding frame. Several clamping blocks are fixed on the clamping sliding frame.

[0019] A method of using the aforementioned disassembly and assembly system for MBR membrane module maintenance includes the following steps: Step 1: The disassembly and assembly system moves to the top of the MBR membrane module to be maintained via an external maintenance trolley. The main frame drive rotates the module from a horizontal position to a vertical position, and the sliding frame and its rotating and clamping modules also turn vertically downward. Step 2: The sliding drive is activated, pushing the sliding frame to extend downwards along the vertical main frame guide rail, causing the clamping module to descend to the height of the MBR membrane module hoisting beam. Then the clamping module moves, and the two sets of clamping ends move towards each other to clamp the frame structure of the membrane module. Step 3: After clamping is completed, the sliding drive reverses its movement, lifting the sliding frame and the clamped membrane module vertically upwards, so that the membrane module is completely separated from the membrane tank. The main frame moves again, rotating the entire main frame from the vertical state back to the horizontal state. Step 4: The external maintenance trolley travels to other areas, and the operator flushes and maintains the MBR membrane module. At the same time, the rotating module is started to adjust the MBR membrane module in the horizontal position. Step 5: After cleaning, reverse the above steps until the MBR membrane module is reinstalled in the corresponding position.

[0020] Compared with the prior art, the above-conceptual technical solution conceived in this application has the following beneficial effects: This system, through the cooperation of the connecting platform, main frame, sliding frame, and sliding drive components, enables the movement of MBR membrane modules, replacing the traditional hoisting method. This ensures that the MBR membrane modules maintain the maximum safe distance from surrounding dense equipment during the transfer path, avoiding the violent collisions that may be caused by the swinging or oblique pulling of traditional hoisting, thus protecting the membrane modules and facilities inside the tank. Furthermore, the horizontal rotation function provided by the rotating module allows operators to easily adjust the orientation of the membrane modules from a fixed position without having to go around or rotate the hoisting equipment. This facilitates cleaning, visual inspection, and parts replacement by operators, effectively reducing the maintenance time of MBR membrane modules and improving the operational efficiency of core maintenance of MBR membrane modules.

[0024] To more clearly illustrate the purpose, technical solution, and beneficial effects of this application, a further detailed description of this application is provided below in conjunction with illustrations and specific embodiments. It should be specifically noted that the specific embodiments described below are only for illustrating the technical content of this application and do not constitute a limitation on the scope of protection of this application.

[0025] In the accompanying drawings of the embodiments of the present invention, the same or similar reference numerals correspond to the same or similar components. In the description of the present invention, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0026] In the description of this invention, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating a connection between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection via an intermediate medium; it can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] Example 1: See Figures 2-14 The present invention provides a disassembly and assembly system for MBR membrane module maintenance, including a connecting platform 1, a main frame 2, a sliding frame 3, a sliding drive component 4, a rotating module 5, and a clamping module 6.

[0028] The connecting platform 1 is used for fixed connection with an external mobile trolley, providing a stable working base for the assembly and disassembly system.

[0029] The main frame 2 is rotatably connected to the connecting platform 1 and can rotate between vertical and horizontal directions. It has a guide rail 21 arranged along its length to facilitate cleaning of the MBR membrane module after lifting.

[0030] The sliding frame 3 is slidably mounted in the guide rail 21 and can extend downward out of the main frame 2. It can rotate synchronously between the vertical and horizontal directions with the rotation of the main frame 2, and always maintains the same relative posture with the main frame 2.

[0031] The sliding drive component 4 is fixedly connected to the main frame 2 and has a sliding telescopic end 41 that can move along the length of the main frame 2. The sliding telescopic end 41 is fixedly connected to the sliding frame 3 and is used to drive the sliding frame 3 to move along the guide rail 21, so that the sliding frame 3 can extend or retract along the guide rail 21. The sliding drive component 4 can be a telescopic structure such as a hydraulic telescopic cylinder or an electric telescopic cylinder.

[0032] The rotating module 5 is fixedly connected to the sliding frame 3 and has a driven rotating frame 51 that can rotate along the height direction of the sliding frame 3, which facilitates the cleaning operation of the MBR membrane module after lifting.

[0033] The clamping module 6 is fixedly connected to the driven rotating frame 51 and has two sets of symmetrically arranged clamping ends 61. The two sets of clamping ends 61 can move in opposite directions and form clamping grooves for clamping the MBR membrane module frame structure.

[0034] Specifically, this example demonstrates how the MBR membrane module can be moved through the cooperation of the connecting platform 1, main frame 2, sliding frame 3, and sliding drive component 4. This replaces the traditional hoisting method, ensuring that the MBR membrane module maintains the maximum safe distance from surrounding dense equipment during the transfer path. It avoids the violent collisions that may be caused by traditional hoisting swings or oblique pulls, protecting the membrane module and facilities inside the tank. Furthermore, the horizontal rotation function provided by the rotating module 5 allows operators to easily adjust the orientation of the membrane module at a fixed position without having to go around or hoist overturn it. This facilitates cleaning, visual inspection, and replacement of parts, effectively reducing the maintenance time of the MBR membrane module and improving the operational efficiency of core maintenance of the MBR membrane module.

[0035] In an optional example, please refer to Figures 2 to 5 As shown, a rotation follower 52 is provided at one end of the rotation module 5 facing the direction closer to the main frame 2. The rotation follower 52 is drivenly connected to the driven rotation frame 51. A drive module 7 is fixed on the main frame 2. A rotatable rotation drive block 71 is provided at one end of the drive module 7 facing the direction closer to the sliding frame 3. The rotation drive block 71 is connected to the main frame 2 by sliding. The sliding frame 3 has a rotation position, and the rotation drive block 71 has a drive position. When the sliding frame 3 is in the rotation position and the rotation drive block 71 is in the drive position, the rotation drive block 71 abuts against the rotation follower 52 to drive the rotation follower 52 to rotate.

[0036] When the membrane assembly needs to be rotated, the sliding drive 4 first precisely moves the sliding frame 3 to the preset rotation position; then the drive module 7 controls its rotation drive block 71 to move from the initial position to the drive position, so that it matches and inserts with the rotation follower 52 on the sliding frame 3 to achieve power docking. After the power docking is completed, the drive module 7 operates, transmitting torque to the rotation follower 52 through the rotation drive block 71, thereby driving the driven rotating frame 51 and the clamped membrane assembly to rotate precisely; after the rotation action is completed, the rotation drive block 71 retracts to the initial position and separates from the rotation follower 52.

[0037] Specifically, in this example, the heavier drive module 7 is fixed to the main frame 2, which reduces the inertia and weight of the sliding frame 3, effectively reducing the equipment size and manufacturing cost of the disassembly and assembly system. Furthermore, the power and signal lines only need to be connected to the drive module 7 on the fixed main frame 2, completely avoiding the problems of cable and hydraulic pipe entanglement, wear or fatigue breakage that may be caused by the repeated lifting and rotation of the sliding frame 3, thus improving the service life of the disassembly and assembly system.

[0038] In an optional example, please refer to Figures 6 to 10 As shown, the rotating module 5 includes a support base 53 that is fixedly connected to the sliding frame 3 by bolts. A rotating base 54 is rotatably mounted on the support base 53 at the end facing away from the main frame 2. The rotation centerline of the rotating base 54 is set along the height direction of the sliding frame 3. The rotating base 54 is fixedly connected to the driven rotating frame 51 by bolts. A rotating shaft 55 is rotatably mounted inside the support base 53. The central axis of the rotating shaft 55 coincides with the central axis of the rotating base 54. One end of the rotating shaft 55 passes through the support base 53 and is drivenly connected to the rotating base 54. The other end of the rotating shaft 55 is drivenly connected to the rotating driven part 52.

[0039] Specifically, this example adopts an independent modular structure design through the transmission between the rotating base 54 and the driven rotating frame 51, which facilitates the quick assembly and disassembly of the rotating module 5. Furthermore, the cooperation between the rotating base 54 and the support base 53 ensures the structural strength of the rotating module 5 and improves the service life of the assembly and disassembly system.

[0040] In an optional example, please refer to Figures 8 to 10As shown, the support base 53 has a support groove 531 at one end facing the rotating base 54, and a support bearing 56 is inserted and fixed in the support groove 531. The rotating base 54 has a rotating flange 541 at one end facing the support base 53, and the rotating flange 541 is inserted into the inner wall of the support bearing 56. The support groove 531 has a support rotation hole 532 that penetrates the support base 53, and the rotating shaft 55 is rotatably inserted into the support rotation hole 532. The rotating base 54 has a rotating protrusion 542 at one end facing the support base 53, and the rotating protrusion 542 has a... A rotary driven groove 543 is provided, and one end of the rotating shaft 55 is inserted into the rotary driven groove 543. A conductive slip ring 57 is fixed in the rotating flange 541 by bolts. The rotor of the conductive slip ring 57 is fixedly connected to the rotating base 54 by bolts. A wiring groove 544 is provided at the end of the rotating base 54 facing away from the supporting base 53. The wiring groove 544 passes through the supporting base 53 and extends into the rotating flange 541. The central axis of the rotating flange 541, the central axis of the rotary driven groove 543, and the central axis of the conductive slip ring 57 coincide. The clamping module 6 is electrically connected to the rotor of the conductive slip ring 57 by wiring.

[0041] Specifically, this example ensures the structural rigidity of the rotating module 5 by connecting the support bearing 56 and the rotating flange 541, enabling it to withstand the torque generated by the heavy membrane assembly for a long time. At the same time, the design of the conductive slip ring 57 and the wiring groove 544 solves the problem of cable entanglement in the rotating module 5, allowing the clamping module 6 to integrate complex functions such as electric and sensing functions.

[0042] In an optional example, please refer to Figures 8 to 12As shown, the rotary driven part 52 includes a rotary housing 521 fixedly connected to the support base 53 by bolts. A rotary guide cavity 522 is formed inside the rotary housing 521 along the central axis of the rotary shaft 55. A transmission clutch block 58, matching the rotary drive block 71, is slidably installed inside the rotary guide cavity 522. A guide groove 581 penetrating the center of the transmission clutch block 58 is formed. One end of the rotary shaft 55 is rotatably inserted into the guide groove 581 via a spline connection. A first spring 59 is provided inside the rotary guide cavity 522. Spring 59 is fitted onto the outer wall of rotating shaft 55. One end of the first spring 59 abuts against transmission clutch block 58, and the other end of the first spring 59 abuts against support base 53. The elastic force of the first spring 59 pushes transmission clutch block 58 to move toward the direction of rotating drive block 71. A driven clutch ring 510 is provided in the rotating guide cavity 522. The driven clutch ring 510 is fixedly connected to support base 53 and can be driven to connect with transmission clutch block 58. When rotating drive block 71, transmission clutch block 58 and driven clutch ring 510 are inserted into each other, the rotating drive block 71 is in a driving position. The rotating housing 521 includes an outer shell and a shell ring that are fixed to each other by bolts. A rotating guide groove is provided on the outer shell, and the shell ring is provided at the end of the rotating guide groove. The rotating guide groove and the shell ring are combined to form rotating guide cavity 522.

[0043] When the sliding frame 3 moves to the precise rotation position, the rotation drive block 71 of the drive module 7 extends to the drive position and presses against the transmission clutch block 58. The transmission clutch block 58 is pushed inward, and the first spring 59 is compressed until the transmission clutch block 58 is fully engaged with both the rotation drive block 71 and the driven clutch ring 510, forming a rigid transmission chain. The drive module 7 works, and the power drives the entire rotation module 5 and the membrane assembly to rotate through this transmission chain. When the rotation ends, the rotation drive block 71 retracts, and the elastic force of the first spring 59 pushes the transmission clutch block 58 back to the initial extended position, disengaging it from the driven clutch ring 510, and the transmission chain is broken.

[0044] Specifically, this example achieves the floating of the transmission clutch block 58 through the cooperation of the first spring 59 and the transmission clutch block 58, which can automatically compensate for axial or radial alignment errors during the docking process, absorb shocks, and achieve smooth and shock-free engagement, greatly protecting the drive module 7 and improving the service life of the drive module 7.

[0045] In an optional example, please refer to Figure 11 , 12As shown, a clutch flange 5101 is provided on the outer wall of the driven clutch ring 510, and a plurality of locking grooves 5102 are provided on the clutch flange 5101. A locking mechanism is fixed on the rotary driven part 52, and the locking mechanism has a locking protrusion 511 that matches the locking groove 5102. The drive module 7 has an abutting active block 72 that moves synchronously with the rotary drive block 71. The abutting active block 72 is used to drive the movement of the locking protrusion 511, so that the locking protrusion 511 can be inserted into the locking groove 5102.

[0046] A rotating groove 523 extending into the rotating guide cavity 522 is provided on the outer wall of the rotating housing 521. The locking protrusion 511 is slidably inserted into the rotating groove 523. A locking guide post 512 is provided at the end of the locking protrusion 511 facing away from the clutch flange 5101. A second spring 513 is fitted on the outer wall of the locking guide post 512. One end of the second spring 513 abuts against the locking protrusion 511, and the other end of the second spring 513 abuts against the rotating groove 523. The elastic force of the second spring 513 pushes the locking protrusion 511 to insert into the locking groove 5102. The end of the locking guide post 512 extends out of the rotating groove 523 and is provided with an extension protrusion 514. A driving structure is provided in the extension protrusion 514. The locking mechanism also includes a push structure, which is connected to the driving structure. When the abutting active block 72 pushes the push structure, the push structure drives the locking protrusion 511 to move away from the locking groove 5102.

[0047] In this embodiment, please refer to Figure 11 , 12 As shown, the driving structure is a wedge-shaped driven groove 5141 set on the extension protrusion 514. The pushing structure includes a driven guide post 515. One end of the driven guide post 515 is provided with a resisting driven block 516 that matches the resisting active block 72. The other end of the driven guide post 515 is connected to a wedge-shaped driving block 517 by bolts. The wedge-shaped driving block 517 can be inserted into the wedge-shaped driven groove 5141 and drive the locking guide post 512 to move away from the locking groove 5102. A third spring 518 is fitted on the outer wall of the driven guide post 515. One end of the third spring 518 abuts against the resisting driven block 516, and the other end of the third spring 518 abuts against the outer wall of the rotating housing 521. The elastic force of the third spring 518 pushes the resisting driven block 516 to move away from the extension protrusion 514.

[0048] The rotary slide 523 has an open structure, and a sealing plate is fixed to the end of the rotary slide 523 by bolt connection. When the driven rotary frame 51 needs to rotate, the drive module 7 simultaneously pushes out the rotary drive block 71 and the abutting active block 72. The abutting active block 72 pushes the abutting driven block 516 to move. The abutting driven block 516 drives the driven guide post 515 to move. The driven guide post 515 drives the wedge drive block 517 to move. The wedge drive block 517 drives the extension protrusion 514 to move. The extension protrusion 514 drives the locking guide post 512 to move. The locking guide post 512 drives the locking protrusion 511 to move until the locking protrusion 511 disengages from the locking groove 5102. At this time, the rotary drive block 71 pushes the transmission clutch block 58 to move towards the driven clutch ring 510 to drive the driven rotary frame 51.

[0049] Specifically, this example achieves the self-locking function of the rotating module 5 through the cooperation of the locking protrusion 511 and the locking groove 5102, ensuring that the driven rotating frame 51 can maintain the angle of suspension, avoiding disorderly rotation of the driven rotating frame 51, and improving the safety of the disassembly and assembly system.

[0050] In an optional example, please refer to Figure 13 , 14 As shown, the drive module 7 includes a drive base 73 fixedly connected to the main frame 2 by bolts. A drive sliding frame 74 is slidably mounted on the drive base 73. A drive motor 75 is fixedly mounted on the drive sliding frame 74 by bolts. A rotary drive block 71 is fixedly connected to the output shaft of the drive motor 75 by a key. The rotary drive block 71 is provided with several drive protrusions 711. A drive telescopic cylinder 76 is fixedly mounted on the drive base 73. The telescopic end of the drive telescopic cylinder 76 is fixedly connected to the drive sliding frame 74 by bolts. The drive sliding frame 74 is provided with a sliding guide post, and a guide slip ring is fixedly mounted on the drive base 73. The sliding guide post is slidably inserted into the guide slip ring.

[0051] Specifically, this example achieves precise movement of the rotary drive block 71 by driving the telescopic cylinder 76 to move the drive sliding frame 74, while the cooperation of the sliding guide post and the guide ring ensures structural rigidity.

[0052] In an optional example, please refer to Figures 2 to 14 As shown, several rotatable guide wheels 31 are fixed on the side wall of the sliding frame 3 by key connection. The guide wheels 31 are slidably inserted into the guide rail 21, and the sliding frame 3 can extend downward from the main frame 2 through the guide rail 21.

[0053] Specifically, this example achieves the movement of the sliding frame 3 through the cooperation of the sliding frame 3 and the guide wheel 31, ensuring the precise displacement of the MBR membrane module. At the same time, the combination of the guide rail 21 and the sliding frame 3 can effectively reduce the manufacturing difficulty and weight of the disassembly and assembly system, and save the manufacturing cost of the disassembly and assembly system.

[0054] In an optional example, please refer to Figures 2 to 5 As shown, the rotation axis 55 of the main frame 2 is set along the width direction of the main frame 2. The connecting platform 1 is fixed to the tilting drive component 22 by means of a rotating shaft. The rotation axis 55 of the tilting drive component 22 is set along the width direction of the main frame 2. The tilting drive component 22 has a retractable tilting telescopic end, which is connected to the main frame 2 by means of a rotating shaft. The rotation axis 55 of the tilting telescopic end is set along the width direction of the main frame 2, allowing the main frame 2 to rotate between the vertical and horizontal directions. The tilting drive component 22 can adopt an electric or hydraulic telescopic cylinder structure.

[0055] Specifically, this example uses the operation of the flipping drive 22 to drive the rotation of the main frame 2, thereby enabling the flipping of other structures in both horizontal and vertical configurations and ensuring the stability of the MBR membrane module during flipping.

[0056] In an optional example, please refer to Figures 2 to 4 As shown, the clamping module 6 includes a clamping base 62 fixedly connected to the driven rotating frame 51 by bolts. The clamping end 61 includes a clamping sliding frame, which is connected to the clamping base 62 along the width direction of the main frame 2 by sliding. A clamping telescopic cylinder 63 is fixedly fixed to the clamping base 62 by bolts. The telescopic end of the clamping telescopic cylinder 63 is fixedly connected to the clamping sliding frame by bolts. Several clamping blocks 64 are fixed on the clamping sliding frame. The clamping telescopic cylinder 63 can be an electric or hydraulic telescopic cylinder, preferably an electric telescopic cylinder, which facilitates the wiring. A clamping ring is provided on the clamping base 62, and a clamping guide post is slidably inserted into the clamping ring. The end of the clamping guide post is fixedly connected to the clamping sliding frame by bolts. The clamping blocks 64 match the frame structure shape of the MBR membrane module.

[0057] Specifically, in this example, the operation of the clamping telescopic cylinder 63 drives the clamping sliding frame to move, and the clamping sliding frame drives the clamping block 64 to move, thereby clamping and fixing the frame structure of the MBR membrane module, achieving rapid fixation of the MBR membrane module.

[0058] Example 2: Based on Example 1, this example also provides a method for using the disassembly and assembly system for MBR membrane module maintenance, including the following steps: Step 1: The disassembly and assembly system travels to the top of the MBR membrane module to be maintained via an external maintenance trolley. The main frame 2 is driven to rotate it from a horizontal position to a vertical position. The sliding frame 3 and its rotating module 5 and clamping module 6 also turn vertically downward. Step 2: The sliding drive component 4 is activated, pushing the sliding frame 3 to extend downward along the guide rail 21 of the vertical main frame 2, so that the clamping module 6 is lowered to the height of the MBR membrane module hoisting beam. Then the clamping module 6 is activated, and the two sets of clamping ends 61 move towards each other to clamp the frame structure of the membrane module. Step 3: After clamping is completed, the sliding drive 4 moves in the opposite direction, lifting the sliding frame 3 and the clamped membrane module vertically upward, so that the membrane module is completely separated from the membrane pool. The main frame 2 moves again, rotating the entire main frame 2 from the vertical state back to the horizontal state. Step 4: The external maintenance trolley travels to other areas, and the operator flushes and maintains the MBR membrane module. At the same time, the rotating module 5 is started to adjust the MBR membrane module in the horizontal direction. Step 5: After cleaning, reverse the above steps until the MBR membrane module is reinstalled in the corresponding position.

[0059] In summary, this invention achieves the movement of MBR membrane modules through the cooperation of the connecting platform 1, main frame 2, sliding frame 3, and sliding drive component 4, replacing the traditional hoisting method. This ensures that the MBR membrane modules maintain the maximum safe distance from surrounding dense equipment during the transfer path, avoiding the violent collisions that may be caused by the swinging or oblique pulling of traditional hoisting, thus protecting the membrane modules and facilities inside the tank. Furthermore, the horizontal rotation function provided by the rotating module 5 allows operators to easily adjust the orientation of the membrane modules at a fixed position without having to go around or flip the hoisting, facilitating cleaning, visual inspection, and replacement of parts. This effectively reduces the maintenance time of the MBR membrane modules and improves the efficiency of core maintenance of the MBR membrane modules. At the same time, fixing the heavier drive module 7 to the main frame 2 reduces the inertia and weight of the sliding frame 3, effectively reducing the equipment size and manufacturing cost of the disassembly and assembly system. Moreover, the power and signal lines only need to be connected to the drive module 7 on the fixed main frame 2, completely avoiding the problems of cable and hydraulic pipe entanglement, wear, or fatigue fracture that may be caused by the repeated lifting and rotating of the sliding frame 3, thus improving the service life of the disassembly and assembly system.
