Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to an MBR membrane cleaning vehicle. Background Technology

[0002] With increasingly stringent environmental protection requirements, higher demands are being placed on wastewater treatment processes and equipment. The MBR (Metal-Bio Bioreactor) process, with its excellent "sludge-water separation" effect and high level of intelligent control, is widely used in wastewater treatment systems. However, existing MBR membrane cleaning technologies, which widely employ fixed cleaning equipment with a single cleaning trajectory, cause localized areas of the MBR membrane surface to be subjected to concentrated high-pressure liquid or brush friction for extended periods, accelerating membrane module wear and deformation. Most cleaning devices can only cover a portion of the surface area, but the edges and seams of the MBR membrane are difficult to reach, easily leaving stubborn contaminants and creating cleaning blind spots. Long-term accumulation of these blind spots significantly reduces membrane flux. Traditional cleaning equipment often relies on electric drive systems, but electrical installations in water-related environments pose safety hazards. Most equipment does not consider the need for a sealed working space; the open cleaning structure significantly increases the risk of wastewater leakage, potentially causing secondary pollution and violating environmental regulations. These technical deficiencies collectively make it difficult for existing MBR membrane cleaning devices to achieve efficient, safe, and comprehensive MBR membrane surface cleaning, becoming a key bottleneck for the promotion of MBR technology. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned problems by providing an MBR membrane cleaning vehicle. Through the collaborative design of the membrane cleaning assembly and the oscillation device, the positional relationship between the MBR membrane and the cleaning module during the cleaning process is dynamically changed, effectively eliminating local high-pressure wear and cleaning blind spots in traditional cleaning. By dispersing the cleaning force through multi-dimensional motion, the efficiency of removing contaminants from the MBR membrane surface is improved, significantly extending the service life of the MBR membrane.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An MBR membrane cleaning vehicle includes a vehicle body on which a membrane cleaning device is mounted. The membrane cleaning device includes a loading device for loading an MBR membrane, a membrane cleaning assembly for cleaning the MBR membrane, and an oscillation device for causing relative displacement between the loading device and the membrane cleaning assembly. The membrane cleaning assembly is matched with the loading device and can clean the MBR membrane inside the loading device. The membrane cleaning assembly includes a support frame and a cleaning module, with the cleaning module mounted on the support frame. The loading device includes a loading pallet and a loading slide, with the loading pallet mounted on the loading slide. The oscillation device can drive the support frame to move relative to the loading device and can drive the loading slide to move relative to the membrane cleaning assembly.

[0006] By employing the aforementioned technical solution, and through the synergistic effect of the membrane washing assembly and the oscillation device, the MBR membrane and the cleaning module can generate relative motion in multiple dimensions. This design significantly reduces the continuous pressure on the MBR membrane surface caused by fixed cleaning, preventing accelerated local wear and thus effectively mitigating membrane damage and extending its service life. The multi-directional displacement also expands the cleaning contact area, effectively removing contaminants from the MBR membrane surface and reducing cleaning dead zones caused by static cleaning, thereby improving the cleaning efficiency of the MBR membrane.

[0007] Furthermore, the cleaning module includes a support body, a high-pressure water spray unit for spraying high-pressure liquid onto the MBR membrane inside the loading device, a rotating brush for contacting and cleaning the MBR membrane inside the loading device, and a rotating drive device; the high-pressure water spray unit is assembled on the support body, the high-pressure water spray unit is externally connected to a high-pressure liquid source device, the rotating brush is rotatably assembled on the support body, and the rotating drive device can drive the rotating brush to rotate.

[0008] Thanks to the above-mentioned technical solution, which combines the high-pressure water spray unit with the rotating brush, the MBR membrane surface can be simultaneously acted upon by the impact of high-pressure liquid and the physical scraping of the rotating brush. This not only effectively removes stubborn stains but also ensures the uniformity and comprehensiveness of the cleaning action. By replacing manual operation with automated cleaning, cleaning efficiency is improved.

[0009] Furthermore, several of the high-pressure water spray units and rotating brushes are spaced apart on the support body along the Z-axis direction; the high-pressure water spray unit includes a spray pipe arranged along the X-axis direction, and several nozzles are arranged on the circumferential sidewall of the spray pipe, the nozzles are in fluid communication with the spray pipe, and the spray pipe is in fluid communication with the high-pressure liquid source device; the rotating brush includes a rotating shaft arranged along the X-axis direction, and several brush bodies are arranged on the circumferential sidewall of the rotating shaft.

[0010] By adopting the above technical solution, the design of the nozzle and rotating shaft along the X-axis forms a fully covered cleaning area in the horizontal direction. Combined with the distribution of high-pressure water spray unit and rotating brush on the Z-axis, it ensures that every area of ​​the MBR membrane cleaning surface is uniformly sprayed with high-pressure liquid and rubbed by the brush body, avoiding cleaning blind spots and improving the overall cleanliness.

[0011] Furthermore, the high-pressure liquid source device includes a water storage unit, a water pump, and a water pipe. The water inlet of the water pump is connected to the water outlet of the water storage unit, and the water outlet is connected to the water inlet of the water pipe. The water outlet of the water pipe is connected to the spray pipe.

[0012] Thanks to the above technical solution, the water storage unit provides a stable liquid source for the system. The water pump pressurizes the liquid used for cleaning and delivers it to the spray nozzle through the water pipe, ensuring that the high-pressure water spray unit can continuously and stably spray high-pressure liquid and maintain a stable cleaning intensity. At the same time, the design of the water storage unit ensures the stability of water supply during continuous operation and avoids the problem of reduced cleaning efficiency due to insufficient external water pressure.

[0013] Furthermore, the support body is a frame structure; the two ends of the nozzle along its length are respectively connected to the opposite side walls of the frame structure, and the nozzle faces the opening end of the frame structure; the two ends of the rotating shaft along its length are respectively rotatably connected to the opposite side walls of the frame structure, and the brush extends from the opening end of the frame structure.

[0014] Thanks to the aforementioned technical solution, a frame structure is used as the support, ensuring stable installation of the nozzle and rotating shaft. The directional design of the opening ends ensures that the nozzle and brush effectively act on the MBR membrane surface. The rigid design of the frame structure improves the stability of the cleaning module, guaranteeing that the components maintain precise positional relationships during movement driven by the oscillation device, preventing displacement or damage.

[0015] Furthermore, the loading tray is provided with several loading positions spaced apart along the Y-axis direction, and several MBR membranes can be loaded in parallel at the corresponding loading positions. The loading tray is also provided with a sewage trough connecting the loading positions to the external environment. Several cleaning modules are assembled at intervals along the Y-axis direction on the support frame. The cleaning modules and loading positions are staggered, so that the cleaning modules can extend between two adjacent MBR membranes.

[0016] By adopting the above technical solution, the staggered loading positions and cleaning modules along the Y-axis enable each cleaning module to penetrate deep between adjacent MBR membranes for cleaning, ensuring cleaning efficiency. At the same time, the parallel and spaced loading method ensures the neat arrangement of MBR membranes, avoids damage to MBR membranes caused by compression, and increases the number of MBR membranes that can be cleaned in a single cycle.

[0017] Furthermore, the oscillation device includes a first oscillation guide rail arranged along the X-axis, a second oscillation guide rail arranged along the Z-axis, and an oscillation driving device. The second oscillation guide rail is disposed on one side of the length direction of the first oscillation guide rail. The loading carriage is assembled on the first oscillation guide rail and can move along the first oscillation guide rail under the action of the oscillation driving device. The support frame is assembled on the second oscillation guide rail and can move along the second oscillation guide rail under the action of the oscillation driving device.

[0018] As a result of the above technical solution, the loading carriage moves along the first oscillating guide rail in the X-axis direction, and the support frame moves along the second oscillating guide rail in the Z-axis direction, forming a composite oscillation path, which improves the flexibility and coverage of the cleaning process.

[0019] Furthermore, the vehicle body is also equipped with a pneumatic drive device. The oscillation drive device includes a first cylinder for driving the slide frame and a second cylinder for driving the support frame. The rotation drive device is a pneumatic motor. The pneumatic drive device includes an air tank, a compressor, and an air pipe. The air inlet of the compressor is connected to the air outlet of the air tank, and the air outlet is connected to the air inlet of the air pipe. The air pipe is connected to the first cylinder, the second cylinder, and the pneumatic motor through multiple air branch lines. Each air branch line is equipped with a control valve to control the on / off state of the air branch line. The control valve is signal-connected to the control device.

[0020] Thanks to the aforementioned technical solution, the air-driven device provides a clean and efficient power source. The combination of the air tank and compressor ensures a continuous and stable supply of compressed air. The design of the air distribution branches and control valves enables independent control of each actuator. The control device precisely regulates the actions of the first cylinder, the second cylinder, and the pneumatic motor, ensuring the accuracy and reliability of the system operation. At the same time, the pneumatic drive avoids the risk of electric shock from operating electric components in water, thereby improving the overall automation level and operational safety of the equipment.

[0021] Furthermore, the vehicle body is also equipped with a lifting device for hoisting the MBR membrane onto the loading device. The lifting device includes a liftable lifting column, a telescopic boom, and a hook. The bottom of the lifting column is mounted on the vehicle body via a base, and the top is connected to one end of the boom. The other end of the boom is connected to a hook. The lifting column and boom are signal-connected to a control device.

[0022] Thanks to the aforementioned technical solution, the equipped lifting device can precisely control the lifting position of the MBR membrane through the lifting column and telescopic boom, safely moving the MBR membrane into or out of the loading device. The linkage between the lifting device and the control device enables automated operation, reducing the labor intensity of manual handling, improving work efficiency, and avoiding damage to the MBR membrane caused by improper manual operation.

[0023] Furthermore, the vehicle body is also equipped with a carriage, the film washing device is installed inside the carriage, and a sewage outlet is provided on one side of the carriage.

[0024] By adopting the above-mentioned technical solution and integrating the membrane washing device inside the carriage, not only is space saved, but a sealed working environment is also provided, reducing the impact of external pollution. The sewage outlet design on the side of the carriage facilitates the centralized discharge and treatment of wastewater generated during cleaning, avoiding secondary pollution to the working environment and better complying with environmental protection regulations.

[0025] In summary, due to the adoption of the above technical solutions, the beneficial effects of this utility model are as follows: Through the coordinated operation of the membrane washing assembly and the oscillation device, multi-dimensional relative motion is generated, dynamically changing the positional relationship between the MBR membrane and the cleaning module. This significantly reduces the risk of continuous high-pressure wear in localized areas caused by fixed cleaning, while avoiding cleaning blind spots on the MBR membrane surface caused by static cleaning. The cleaning module utilizes the dual force of high-pressure liquid jetting and physical scraping by rotating brushes to effectively remove stubborn sand particles and large particulate contaminants adhering to the MBR membrane surface. Furthermore, the use of an air-driven device to provide driving force avoids electrical safety risks during water-related operations compared to conventional electric drive devices. The lifting device integrated into the vehicle body, through its liftable lifting column and telescopic boom, automates the loading and unloading of the MBR membrane assembly, reducing the risk of membrane scratches or deformation caused by improper handling during manual transport. The overall design reduces secondary pollution of wastewater through a sealed compartment, comprehensively solving the core problems of severe membrane fouling, short service life, and difficult maintenance in wastewater treatment scenarios.

[0037] Example 1

[0038] An MBR membrane cleaning vehicle includes a vehicle body 1, on which a membrane cleaning device 5 is mounted. The membrane cleaning device 5 includes a loading device 55 for loading an MBR membrane, a membrane cleaning assembly 53 for cleaning the MBR membrane, and an oscillation device for causing relative displacement between the loading device 55 and the membrane cleaning assembly 53. The membrane cleaning assembly 53 is matched with the loading device 55 and can clean the MBR membrane inside the loading device 55. The membrane cleaning assembly 53 includes a support frame 531 and a cleaning module 534, with the cleaning module 534 mounted on the support frame 531. The loading device 55 includes a loading tray 551 and a loading carriage 552, with the loading tray 551 mounted on the loading carriage 552. The oscillation device can drive the support frame 531 to move relative to the loading device 55 and can drive the loading carriage 552 to move relative to the membrane cleaning assembly 53. Specifically, by synergistically combining the membrane washing assembly 53 and the oscillation device, the MBR membrane and the cleaning module 534 can generate relative motion in multiple dimensions. This design significantly reduces the continuous pressure on the MBR membrane surface caused by fixed cleaning, avoids accelerated local wear, and thus effectively slows down membrane damage and extends service life. Multi-directional displacement also expands the cleaning contact area, effectively removing contaminants from the MBR membrane surface and reducing cleaning dead zones caused by static cleaning, thereby improving the cleaning efficiency of the MBR membrane.

[0039] The cleaning module 534 includes a support body 5341, a high-pressure water spray unit for spraying high-pressure liquid onto the MBR membrane inside the loading device 55, a rotating brush 5343 for contacting and cleaning the MBR membrane inside the loading device 55, and a rotation drive device. The high-pressure water spray unit is mounted on the support body 5341 and is externally connected to a high-pressure liquid source device 6. The rotating brush 5343 is rotatably mounted on the support body 5341, and the rotation drive device can drive the rotating brush 5343 to rotate. Specifically, by combining the synergistic effect of the high-pressure water spray unit and the rotating brush 5343, the MBR membrane surface can be simultaneously acted upon by the impact of high-pressure liquid and the physical scraping of the rotating brush 5343. This not only effectively removes stubborn stains but also ensures the uniformity and comprehensiveness of the cleaning action. By replacing manual operation with automated cleaning, cleaning efficiency is improved.

[0040] A high-pressure water spray unit and a rotating brush 5343 are spaced apart along the Z-axis on the support body 5341. The number of high-pressure water spray units and rotating brushes 5343 can be set according to requirements. The high-pressure water spray unit includes a spray pipe 5342 arranged along the X-axis. Multiple nozzles 5345 are arranged on the circumferential sidewall of the spray pipe 5342. The nozzles 5345 are in fluid communication with the spray pipe 5342, and the spray pipe 5342 is in fluid communication with the high-pressure liquid source device 6. The rotating brush 5343 includes a rotating shaft arranged along the X-axis. Several brush bodies are arranged on the circumferential sidewall of the rotating shaft. Specifically, through the design of the spray pipe 5342 and rotating shaft along the X-axis, a fully covered cleaning area is formed in the horizontal direction. Combined with the distribution of the high-pressure water spray unit and rotating brushes 5343 on the Z-axis, it is ensured that every area of ​​the MBR membrane cleaning surface is uniformly sprayed with high-pressure liquid and rubbed by brush bodies, avoiding cleaning blind spots and improving overall cleanliness.

[0041] The high-pressure liquid source device 6 includes a water storage unit, a water pump 61, and a water pipe 62. The inlet of the water pump 61 is connected to the outlet of the water storage unit, and the outlet is connected to the inlet of the water pipe 62. The outlet of the water pipe 62 is connected to the spray nozzle 5342. Specifically, the water storage unit provides a stable liquid source reserve for the system. The water pump 61 pressurizes the liquid used for cleaning and delivers it to the spray nozzle 5342 through the water pipe 62, ensuring that the high-pressure water spray unit can continuously and stably spray high-pressure liquid and maintain a stable cleaning intensity. At the same time, the design of the water storage unit ensures the stability of water supply during continuous operation and avoids the problem of reduced cleaning efficiency due to insufficient external water pressure.

[0042] The support 5341 is a frame structure; the two ends of the nozzle 5342 along its length are respectively connected to the opposite side walls of the frame structure, and the nozzle 5345 faces the open end of the frame structure; the two ends of the rotating shaft along its length are rotatably connected to the opposite side walls of the frame structure, and the brush extends from the open end of the frame structure. Specifically, using a frame structure as the support 5341 allows the nozzle 5342 and the rotating shaft to be stably installed, and the design of the open end direction ensures that the nozzle 5345 and the brush effectively act on the MBR membrane surface. The rigid design of the frame structure improves the stability of the cleaning module 534, ensuring that the components maintain a precise positional relationship during movement driven by the oscillation device, avoiding displacement or damage caused by shift.

[0043] The loading tray 551 is provided with several loading positions spaced apart along the Y-axis direction. Figure 3 The system is equipped with six loading positions, allowing for the simultaneous cleaning of six MBR membranes. The number of loading positions can be adjusted as needed. The six MBR membranes can be loaded in parallel at intervals in their respective loading positions. The bottom of the MBR membranes can be inserted into the slots formed by the loading positions for fixation. The loading tray 551 is also equipped with a drain trough connecting the loading positions to the external environment. Several cleaning modules 534 are spaced apart along the Y-axis on the support frame 531. Figure 3 The system includes six cleaning modules 534, the number of which can be adjusted as needed. These cleaning modules 534 are staggered with the loading positions, allowing them to extend between adjacent MBR membranes. Specifically, the spaced loading positions along the Y-axis and the staggered arrangement of the cleaning modules 534 enable each module to penetrate deep between adjacent MBR membranes for cleaning, ensuring cleaning efficiency. Simultaneously, the parallel, spaced loading method ensures the neat arrangement of the MBR membranes, preventing damage caused by compression and increasing the number of MBR membranes that can be cleaned in a single cycle.

[0044] The oscillation device includes a first oscillation guide rail 56 arranged along the X-axis, a second oscillation guide rail 54 arranged along the Z-axis, and an oscillation drive device. The second oscillation guide rail 54 is located on one side of the length direction of the first oscillation guide rail 56. The loading carriage 552 is mounted on the first oscillation guide rail 56 and can move along the first oscillation guide rail 56 under the action of the oscillation drive device. The support frame 531 is mounted on the second oscillation guide rail 54 and can move along the second oscillation guide rail 54 under the action of the oscillation drive device. Specifically, the loading carriage 552 moves along the first oscillation guide rail 56 in the X-axis direction, and the support frame 531 moves along the second oscillation guide rail 54 in the Z-axis direction, forming a composite oscillation path, which improves the flexibility and coverage of the cleaning process.

[0045] The vehicle body 1 is also equipped with a pneumatic drive unit 4. The oscillation drive unit includes a first cylinder 51 for driving the carrier slide and a second cylinder 52 for driving the support frame 531. The rotation drive unit is a pneumatic motor 5344. The pneumatic drive unit 4 includes an air tank 41, a compressor 43, and an air pipe 44. The air inlet of the compressor 43 is connected to the air outlet of the air tank 41, and the air outlet is connected to the air inlet of the air pipe 44. The air pipe 44 is connected to the first cylinder 51, the second cylinder 52, and the pneumatic motor 5344 through multiple air branch lines. Each air branch line is equipped with a control valve to control the on / off state of the air branch line. The control valve is signal-connected to the control device 31. Specifically, the pneumatic drive unit 4 provides a clean and efficient power source. The combination of the air tank 41 and the compressor 43 ensures a continuous and stable supply of compressed air. The design of the air distribution branches and control valves enables independent control of each actuator. The control device 31 precisely regulates the actions of the first cylinder 51, the second cylinder 52, and the pneumatic motor 5344, ensuring the accuracy and reliability of the system operation. Simultaneously, the pneumatic drive avoids the risk of electric shock from operating electric components in water, thereby improving the overall automation level and operational safety of the equipment. The control device 31, as shown... Figure 1 As shown, it can be installed on the carriage 3 or in any location such as the driver's cab. Preferably, a dry air compressor 42 is also provided between the compressor 43 and the air receiver.

[0046] The vehicle body 1 is also equipped with a lifting device 2 for hoisting the MBR membrane onto the loading device 55. The lifting device 2 includes a liftable lifting column 22, a telescopic boom 23, and a hook 24. The bottom of the lifting column 22 is mounted to the vehicle body 1 via a base 21, and the top is connected to one end of the boom 23. The other end of the boom 23 is connected to the hook 24. The lifting column 22 and the boom 23 are signal-connected to the control device 31. Specifically, the lifting device 2 can precisely control the hoisting position of the MBR membrane through the lifting column 22 and the telescopic boom 23, safely moving the MBR membrane into or out of the loading device 55. The linkage between the lifting device 2 and the control device 31 achieves automated operation, reduces the labor intensity of manual handling, improves work efficiency, and avoids damage to the MBR membrane caused by improper manual operation.

[0047] The vehicle body 1 is also equipped with a carriage 3, and the film washing device 5 is installed inside the carriage 3. A drain outlet 33 is provided on one side of the carriage 3. Specifically, integrating the film washing device 5 inside the carriage 3 not only saves space but also provides a sealed working environment, reducing the impact of external pollution. The drain outlet 33 on the side of the carriage 3 is designed to facilitate the centralized discharge and treatment of wastewater generated during cleaning, avoiding secondary pollution to the working environment and better complying with environmental protection regulations. The vehicle body 1 is also equipped with a power supply 32 to power the equipment on the vehicle that requires electricity.

[0048] The operation process of the MBR membrane cleaning vehicle is as follows: First, the MBR membrane to be cleaned is lifted from the sewage treatment tank by the hook 24 of the lifting device 2, and then precisely positioned on the loading position of the loading pallet 551 by the lifting column 22 and the boom 23. Then, the control device 31 starts the high-pressure liquid source device 6 and the air source drive device 4. The liquid pressurized by the high-pressure water pump 61 is evenly sprayed onto the surface of the MBR membrane through the nozzle 5345. At the same time, the rotating drive device drives the rotating brush 5343 to physically rub the MBR membrane surface. At this time, the oscillation drive device drives the loading slide 552 to move back and forth along the X-axis, and synchronously drives the support frame 531 to move back and forth along the Z-axis, so that the loading pallet 551 with the MBR membrane module and the cleaning module 534 form a compound oscillation cleaning trajectory. The sewage after cleaning is discharged into the sewage outlet 33 of the truck body 3 through the sewage trough of the loading pallet 551, realizing standardized sewage discharge. The entire process requires no manual contact with the MBR membrane components. Through programmed path planning and pneumatic contactless drive, the integrity of the MBR membrane and the safety of the working environment are effectively guaranteed.
