Description

Technical Field

[0001] The invention relates to an MCR automatic cleaning device and belongs to the technical field of printing and dyeing wastewater treatment. Background Art

[0002] Membrane chemical reactor (MCR) combines chemical coagulation and membrane separation, which can effectively remove colloids, suspended particles and other substances in printing and dyeing wastewater. MCR improves the reaction efficiency of traditional chemical coagulation, has the advantages of no need to add chemicals, good effluent quality, flexible operation, etc. However, the membrane surface is prone to clogging and contamination, resulting in reduced membrane separation performance, so the membrane needs to be cleaned to ensure membrane efficiency.

[0003] MCR membrane is generally used in MCR membrane components composed of multiple diaphragms. There is an installation gap between each diaphragm. The current flushing device of MCR membrane components is mainly a high-pressure water gun. The flushing is done by hand-held water guns. During the flushing process, the flushing direction is difficult to control. A large force is required to control the high-pressure water gun during flushing, making it difficult to flush the MCR membrane components in all directions. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an MCR automatic cleaning device, which solves the problems in the prior art of easy waste of flushing water and inaccurate flushing direction during manual flushing.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical scheme: an MCR automatic cleaning device comprises a cleaning water tank, a cleaning table is arranged at the center of the cleaning water tank for placing the MCR membrane assembly to be cleaned;

[0006] The washing table is provided with an annular slide rail, and at least two flushing components that can be operated around the center of the washing table are provided on the washing table through the annular slide rail, and the flushing components include a high-pressure nozzle, and a water supply pipe is connected to the high-pressure nozzle, and a water supply component is provided at the other end of the water supply pipe;

[0007] The water supply pipe can move synchronously with the flushing assembly;

[0008] By adopting the above technical scheme, the flushing component can be quickly controlled to move to various directions of the MCR membrane component through the annular slide rail, and various directions of the MCR membrane component can be flushed. The flushing component does not need to be manually held, and each flushing component is driven by a machine. The flushing component can rotate forward and reverse on the annular slide rail. Since the MCR membrane component is spliced ​​with pieces of MCR membrane plates, there are gaps between the MCR membrane plates. Two flushing components are arranged in coordination. When flushing, two flushing water flows can pass through the gaps and collide with each other to generate convection, so that the flushing water flows to the inside of the MCR membrane component and diffuses. This makes the flushing component not only able to quickly flush the external stains of the MCR membrane component, but also able to flush the internal stains of the MCR membrane component through the coordinated flushing of the two flushing components. Through the convection flushing between the two flushing components at different angles, the cleaning liquid inside the MCR component after the two convections can also flow in different directions, thereby flushing most of the area inside the MCR module.

[0009] The present invention is further configured as follows: the annular slide rail comprises an outer ring slide rail and an inner ring slide rail.

[0010] By adopting the above technical solution, the flushing assembly can be stably installed on the cleaning table, and the outer ring slide rail and the inner ring slide rail cooperate to slide and clamp the flushing assembly. The two tracks simultaneously limit the flushing assembly to ensure that the flushing assembly will not shake due to excessive water pressure recoil force during flushing, and ensure that the flushing assembly can rotate smoothly on the cleaning table.

[0011] The present invention is further configured as follows: a transmission tooth is arranged on the outer side wall of the inner ring slide rail for power rotation of the flushing assembly, the flushing assembly includes a mounting platform, a power gear meshing with the transmission tooth is arranged at the center of the mounting platform, and the power gear is provided with a driver.

[0012] By adopting the above technical solution, by directly setting the transmission gear on the outer wall of the inner ring slide rail, the overall structure can be made more compact and the space occupation can be reduced, which is particularly important for application scenarios with limited space. The gear transmission system is relatively simple and durable, and the maintenance cost is low. When necessary, the transmission parts can be easily inspected and replaced.

[0013] The present invention is further configured as follows: an inner slide groove and an outer slide groove are also provided on the mounting platform, the inner slide groove, the outer slide groove and the power gear are arranged on the same surface of the mounting platform, and a high-pressure nozzle and an angle adjustment component for installing the high-pressure nozzle are provided on the other surface of the mounting platform, and the high-pressure nozzle is swung by controlling the angle adjustment component.

[0014] By adopting the above technical scheme, the outer slide groove and the inner slide groove on each mounting platform are respectively engaged with the outer ring slide rail and the inner ring slide rail, so as to support and guide the mounting platform. At the same time, the power gear is engaged with the engaging teeth arranged on the inner ring slide rail, and the power gear is driven to rotate by the driver. Since the inner ring slide rail is fixed, the power gear performs a circular motion around the inner ring slide rail after rotation, thereby driving the entire flushing assembly to move. By adopting the power transmission method of the gear, the driving force of the entire device is stronger, and with the engagement of the slide rail, the entire flushing assembly can maintain a high stability during rotation flushing.

[0015] The present invention is further configured as follows: a support column with an inner cavity is provided between the cleaning table and the bottom plate of the cleaning water tank, a connecting column extends downward from the bottom surface of the inner cavity of the support column, and an outer wall of the inner cavity area of ​​the support column is provided with an open groove for rotatably installing the water supply component.

[0016] By adopting the above technical solution, the support column supports the cleaning table, the water supply component is installed in the bottom area of ​​the support column, and the liquid suction ring tube in the water supply component rotates around the support column during the circular rotation of the flushing component to stir the cleaning liquid in the cleaning water tank.

[0017] The present invention is further configured as follows: the water supply assembly includes a water supply pump arranged in the inner cavity of the support column and a liquid suction ring tube arranged on the outer wall of the support column, the inner circle of the liquid suction ring tube extends with a clamping protrusion in the direction of the center of the circle, the liquid suction ring tube is rotatably connected to the open groove through the clamping protrusion, the liquid suction ring tube is provided with an absorption hole for connecting the cleaning water tank and the inner cavity of the support column, the liquid suction ring tube is provided with a water supply connector, the water supply connector is connected to one end of the water supply pipe, and the other end of the water supply pipe is connected to the flushing assembly.

[0018] By adopting the above technical solution, during flushing, the water supply assembly connected to the flushing assembly rotates together with the high-pressure nozzle. Since the water supply assembly is located at the center of the cleaning water tank, the cleaning liquid in the cleaning water tank can be stirred during the rotation of the water supply assembly to mix the cleaning liquid evenly.

[0019] The present invention is further configured as follows: the absorption holes are equidistantly arranged on the outer ring of the suction ring tube, the absorption holes are communicated with the inner cavity of the suction ring tube, and the inner cavity of the suction ring tube is rotationally connected to the water supply pump through a connecting pipe.

[0020] By adopting the above technical scheme, the absorption hole is used to absorb the cleaning liquid in the cleaning water tank, and after being absorbed through the absorption hole, it enters the inner cavity of the support column, is absorbed by the water supply pump arranged in the inner cavity of the support column, and is pumped into the water supply pipe through the pump water pipe connector, and finally is sprayed out from the high-pressure nozzle after passing through the pressure valve. Through the setting of multiple absorption holes, the liquid suction ring tube can quickly absorb the cleaning liquid, so that the cleaning liquid supply of the high-pressure nozzle is sufficient and there will be no insufficient pressure.

[0021] The present invention is further configured as follows: the cleaning water tank includes a water supply tank, and a sewage drain tank is arranged on the outer ring of the water supply tank.

[0022] By adopting the above technical solution, the water supply tank is used to hold the cleaning liquid, and the sewage tank is used to collect the waste liquid after flushing. The setting of the sewage tank makes it more convenient and quick to clean up impurities and pollutants, reducing the difficulty and time cost of maintenance work. By collecting and reasonably treating the sewage in the water supply tank through the sewage tank, it can reduce pollution to the environment, and also meet the requirements of environmental protection and energy saving.

[0023] The present invention is further configured as follows: the outer ring slide rail encloses a collecting chamber on the cleaning table, a support rod is arranged between the inner ring slide rail and the cleaning table surface, the inner ring slide rail and the cleaning table bottom plate are isolated by the support rod to form a gap for waste liquid discharge, and the collecting chamber is provided with a drain valve.

[0024] By adopting the above technical solution, the waste liquid collected in the collection chamber is transferred to the drain tank through the drain valve, and the inner ring slide rail and the table surface of the cleaning table are connected by a support rod, so that the inner ring slide rail and the table surface of the cleaning table do not contact each other, which can ensure that the waste liquid falling after flushing flows smoothly to the edge of the cleaning table, is absorbed by the drain valve and then discharged into the drain tank.

[0025] The present invention is further configured as follows: an identification camera for capturing pollutants on the MCR membrane assembly is arranged on the annular slide rail.

[0026] By adopting the above technical solution, the recognition camera can monitor the cleaning status of the MCR membrane component in real time during the flushing process of the flushing component, so that the cleaning personnel can accurately judge whether the cleaning meets the standards.

[0027] The beneficial effects of the present invention are: the MCR membrane component can be automatically flushed, and the flushing component can be rotated on the cleaning table through the slide rail by cooperating with the annular slide rail. During flushing, 360-degree all-round flushing can be achieved without manual operation. At the same time, through the coordinated flushing of the two flushing components, when the flushing components are rotated to the optimal angle, two symmetrical flushing liquids can be injected into the interior of the MCR membrane component along the installation gap, and diffuse around the MCR membrane component after convection inside the MCR membrane component, so that the cleaning liquid can be flushed into the interior of the MCR membrane component to clean the internal stains. During cleaning, the cleaning liquid in the cleaning water tank is stirred and mixed by the rotation of the liquid suction ring tube. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0037] like Figure 1 As shown, the MCR automatic cleaning device includes a cleaning water tank 1, a cleaning table 2 is arranged in the center of the cleaning water tank 1, an annular slide rail 4 is arranged on the cleaning table 2, a flushing component 5 which can rotate forward and reversely around the center of the cleaning table 2 is arranged on the cleaning table 2 through the annular slide rail 4, and the flushing component 5 includes a high-pressure nozzle 501, and the high-pressure nozzle 501 is connected to a water supply pipe 8. The high-pressure nozzle 501 uses a high-pressure water gun, which can automatically draw cleaning liquid in the water supply pipe 8. Corresponding cleaning agents are added to the cleaning liquid, such as cleaning chlorine, cleaning lemon liquid, etc., which are fully mixed in the cleaning water tank 1 and then sprayed out. By using an automatic device to control the high-pressure nozzle 501, no manual operation is required, and the flushing angle can be automatically adjusted, so that the MCR membrane component 3 can be quickly and accurately flushed in all directions.

[0038] During the flushing process, the flushing component 5 rotates through the power gear 503, wherein the transmission gear 4021 meshing with the power gear 503 is fixed by the inner ring slide rail 402. Therefore, after the power gear 503 rotates, it drives the entire flushing component to move around the transmission gear 4021. The MCR membrane component 3 on the cleaning table 2 can be flushed in all directions by the flushing component 5 as the flushing component 5 rotates around the MCR membrane component 5 in the forward and reverse directions and flushes it.

[0039] During the process of the flushing component 5 rotating around the inner ring slide rail 402, when the flushing components 5 rotate to the point where the flushing direction of the cleaning liquid is parallel to the installation gap 15 of the MCR membrane component 3, and the two flushing components 5 are symmetrically arranged at both ends of the installation gap 15, when the cleaning liquid passes through the gap, the two streams of cleaning liquid generate convection in the middle area of ​​the installation gap 15, thereby causing the cleaning liquid to diffuse around the inside of the MCR membrane component 3, so that the inside of the MCR membrane component 3 can also be cleaned more thoroughly.

[0040] The other end of the water supply pipe 8 is connected to the water supply assembly 7, and the water supply pipe 8 and the water supply assembly 7 move synchronously with the flushing assembly 5 when the flushing assembly 5 rotates. During flushing, the water supply assembly 7 connected to the flushing assembly 5 moves around the support column 11 together with the high-pressure nozzle 501. Since the water supply assembly 7 is located at the center of the washing water tank 1, during the rotation of the water supply assembly 7, the water supply pipe 8 arranged in the washing water tank 1 rotates with the water supply assembly 7, which can stir the cleaning liquid in the washing water tank 1 and stir the cleaning liquid evenly.

[0041] The MCR membrane assembly 3 to be cleaned is set directly above the cleaning table 2 by a lifting device. The number of flushing assemblies 5 set on the annular slide rail 4 is generally set to two. When it is necessary to flush the internal center area of ​​the MCR membrane assembly 3, the two flushing assemblies 5 are controlled to rotate to a symmetrical position, and the spray direction of the cleaning liquid is controlled to be parallel to the installation gap between the MCR diaphragms 301.

[0042] like Figure 4 As shown, the annular slide rail 4 includes an outer ring slide rail 401 arranged on the outer ring of the washing table 2, and an inner ring slide rail 402 arranged on the washing table 2 concentrically with the outer ring slide rail 401. The outer ring slide rail 401 cooperates with the inner ring slide rail 402 to slide and clamp the flushing component 5. The two tracks simultaneously limit the flushing component 5 to ensure that the flushing component 5 will not shake due to excessive water pressure recoil force during flushing, so that the flushing component 5 can smoothly rotate on the washing table 2.

[0043] A transmission clamping tooth 4021 is arranged on the outer wall of the inner ring slide rail 402. The transmission clamping tooth 4021 meshes with the power gear 503 arranged at the center of the mounting platform 502, and the power gear 503 is controlled to rotate by the driver 504, and the outer ring of the transmission clamping tooth 4021 rotates, driving the entire flushing assembly 5 to realize movement, wherein the driver 504 is specifically a driving motor, and the driver 504 is arranged in an inverted manner at the center of the mounting platform 502, and the driving shaft at the lower end penetrates the mounting platform 502 and is connected to the power gear 503, and a rotation gap is left between the power gear 503 and the lower surface of the mounting platform 502.

[0044] like Figure 3 and Figure 5 As shown, the MCR diaphragm 301 adopts a curtain membrane, and a plurality of curtain membranes are installed in a frame to form an MCR membrane assembly 3. In the MCR membrane assembly 3 assembled in this way, corresponding installation intervals are left between each curtain membrane. The cleaning liquid sprayed by the flushing assembly 5 passes through the installation interval and enters the interior of the MCR membrane assembly 3. The two flushing liquids collide with each other inside the MCR membrane assembly 3 to generate convection, so that the flushing direction of the cleaning liquid changes. Figure 2 The convection direction generated by the two high-pressure nozzles 501 is the vertical direction. Figure 4 The convection direction generated by the medium and high pressure nozzles 501 after spraying is a horizontal flow perspective, wherein the straight arrow is the spraying direction of the high pressure nozzle, and the curved arrow is the diffusion direction of the cleaning liquid after convection. After convection, the cleaning liquid diffuses rapidly in various reverse directions inside the MCR membrane assembly 3.

[0045] The flushing water flows to the inside of the MCR membrane assembly 3 and diffuses, which enables the flushing assembly 5 to not only quickly flush the external stains of the MCR membrane assembly 3, but also flush the stains inside the MCR membrane assembly 3 through the coordinated flushing of the two flushing assemblies 5. Through the flushing between the two flushing assemblies 5 at different angles, the cleaning liquid inside the MCR assembly can also flow in different directions after the two convections. Through this convection method, a large amount of cleaning liquid is flushed into the interior of the MCR membrane assembly 3, and the MCR membrane assembly 3 is cleaned in an all-round manner, so that the MCR membrane assembly 3 can be cleaned more thoroughly without disassembly, thereby improving the cleaning efficiency of the MCR membrane assembly 3.

[0046] like Figure 7 As shown, the mounting platform 502 is also provided with an outer slide groove 507 and an inner slide groove 505 for clamping the outer ring slide rail 401 and the inner ring slide rail 402. The two and the power gear 503 are arranged on the same surface of the mounting platform 502. The other surface of the mounting platform 502 is provided with a high-pressure nozzle 501 and an angle adjustment component 506 for installing the high-pressure nozzle 501. The angle adjustment component 506 is composed of a fixed bottom plate 5062 and two supporting side plates 5063. The two supporting side plates 5063 are processed with a plurality of angle adjustment components for installing the high-pressure nozzle 501. The high-pressure nozzle 501 has a mounting hole 5064, and support cylinders 5011 for mounting are extended from both sides of the high-pressure nozzle 501. By inserting the support cylinder 5011 into the mounting hole 5064 and connecting the support cylinder 5011 on one side to the power motor 5061, the swing angle of the high-pressure nozzle 501 can be adjusted by driving the power motor 5061, so that the spray angle of the high-pressure nozzle 501 can be changed by controlling the swing through the angle adjustment component 506, thereby achieving all-round flushing.

[0047] The pitch angle of the high-pressure nozzle 501 is adjusted to 120 degrees (±60 degrees). Based on the image recognition results, feedback is given to the operator to adjust the flushing direction of the flushing device. The system optimizes the flushing program by adjusting parameters such as the cleaning medium and flushing time. The flushing device flushes the designated area according to the system instructions.

[0048] The equipment control unit that controls the automatic cleaning of the entire device includes photoelectric sensors, I / O, motion control, level conversion units, etc. It determines the position and status of the object being tested through detection data, informs the image sensor to perform correct acquisition or completes the control of the production process based on the image processing results.

[0049] Each mounting platform 502 is provided with an outer slide groove 507 and an inner slide groove 505, which are respectively engaged with the outer ring slide rail 401 and the inner ring slide rail 402, so as to support and guide the mounting platform 502. At the same time, the power gear 503 is engaged with the engaging teeth arranged on the inner ring slide rail 402, and the power gear 503 is driven to rotate by the driver 504. Since the inner ring slide rail 402 is fixed, the power gear 503 performs a circular motion around the inner ring slide rail 402 after rotation, thereby driving the entire flushing assembly 5 to move. By adopting the power transmission method of the gear, the driving force of the entire device is sufficient, and with the engagement of the slide rail, the entire flushing assembly 5 can maintain a high stability during rotation flushing.

[0050] like Figure 3 As shown, the washing table 2 is connected to the bottom plate of the washing water tank 1 through a support column 11, and the water supply component 7 is installed through the support column 11. An inner cavity for installing a water supply pump 701 is provided at the bottom of the support column 11. The water supply component 7 includes a water supply pump 701 arranged in the inner cavity of the support column 11 and a liquid suction ring tube 702 rotatably connected to the outer ring of the support column 11, and a water supply connector 703 is provided on the liquid suction ring tube 702.

[0051] The liquid suction ring tube 702 is provided with a transition cavity, and the absorption hole 704 arranged on the outer wall of the liquid suction ring tube 702 connects the transition cavity with the cleaning water tank 1. At the same time, a connecting hose is arranged in the transition cavity to connect the water supply connector 703 and the connecting pipe 7021 to each other. The connecting pipe 7021 is rotatably connected to the water outlet of the water supply pump 701, and a sealing ring is provided at the connection between the two. The connecting pipe 7021 adopts a flexible hose-like pipe.

[0052] The support column 11 supports the cleaning table 2, and the water supply component 7 is installed in the bottom area of ​​the support column 11, wherein the liquid suction ring tube 702 in the water supply component 7 rotates around the support column 11 during the circular rotation of the flushing component 5. During the rotation, a vortex is formed in the cleaning water tank 1, and a large amount of cleaning liquid is gathered in the liquid suction ring tube 702, thereby accelerating the absorption speed of the liquid suction ring tube 702, ensuring that the flushing component 5 can have sufficient water pressure during the flushing process.

[0053] The cleaning water tank 1 includes a water supply tank 101, which is provided with a water inlet pipe 13, through which cleaning liquid is introduced into the water supply tank 101, and a sewage trough 102 is provided on the outer circle of the water supply tank 101, and a water outlet pipe 14 is connected to the side wall of the sewage trough 102, and the waste water discharged into the sewage trough 102 by the sewage valve 9 is discharged through the water outlet pipe 14.

[0054] The water supply tank 101 is used to contain cleaning liquid. The entire cleaning table 2 is arranged at the center of the water supply tank 101 through the support column 11, and the sewage tank 102 is used to collect the waste liquid after flushing.

[0055] like Figure 4 As shown, the outer ring slide rail 401 surrounds a collection cavity on the cleaning table 2. The bottom plate of the collection cavity is the bottom plate of the cleaning table 2. The center of the bottom plate is the highest, and the height gradually decreases from the center position to the outer ring. The inner ring slide rail 402 is connected to the table top of the cleaning table 2 through a support rod 12. The number of support rods 12 is equidistantly distributed between the bottom plate of the cleaning table 2 and the inner ring slide rail 402 to support the inner ring slide rail 402. The inner ring slide rail 402 is supported by the support rod 12 to prevent the inner ring slide rail 402 from directly contacting the inner ring slide rail 402. The bottom plate of the collecting chamber is in contact with the collecting chamber, which will not block the flow of sewage, so that the cleaning waste water falling into the collecting chamber can be discharged smoothly. A drain valve 9 is arranged in the collecting chamber, and the drain valve 9 includes a suction pump, a hose connecting the suction pump and the drain valve, and a drain pipe connecting the drain valve and the drain tank 102. During the flushing process, the waste water falling into the collecting chamber flows around the collecting chamber, is absorbed by the suction pump, and is discharged into the drain tank 102. The drain valve 9 is used to transfer the waste liquid in the collecting chamber to the drain tank 102.

[0056] An identification camera 6 for capturing pollutants on the MCR membrane assembly 3 is arranged on the annular slide rail 4 .

[0057] During the flushing process of the flushing component 5, the recognition camera 6 can automatically and quickly identify the MCR membrane component 3, thereby distinguishing the degree of contamination in each area, and then flushing different areas to different degrees. Through the setting of the recognition camera 6, the cleaning efficiency of the entire device is greatly increased, and the contaminated area on the MCR membrane component 3 can be automatically detected without manual control of the direction, thereby automatically and quickly flushing the MCR membrane component 3.

[0058] like Figure 6 As shown, the recognition camera 6 installed on each mounting platform 502 can effectively and quickly capture the area with stains and feed back to the operator, so that the corresponding area can be quickly rinsed.

[0059] like Figure 5 As shown, the outer ring of the liquid suction ring 702 is equidistantly provided with a plurality of absorption holes 704, and the absorption holes 704 are used to absorb the cleaning liquid in the cleaning water tank 1, and after being absorbed through the absorption holes 704, enter the inner cavity of the support column 11, and after being absorbed by the water supply pump 701 arranged in the inner cavity of the support column 11, it is pumped into the water supply pipe 8 through the pump water pipe connector, and finally sprayed out from the high-pressure nozzle 501 after passing through the pressure valve 10. The absorption holes 704 are connected to the inner cavity of the liquid suction ring 702, and the inner cavity of the liquid suction ring 702 is rotatably connected to the water supply pump 701 through the connecting pipe 7021. The water supply pipe 8 is made of a hard tensile tube, which can rotate with the rotation of the flushing component 5 and stir the cleaning liquid in the cleaning water tank 1 for mixing.

[0060] like Figure 2As shown, the MCR membrane assembly 3 is composed of multiple MCR membranes 302 installed on a mounting frame 301. The MCR membrane 302 is made of high-strength PVDF hollow fiber material, and is reinforced inside to provide high strength. When used in printing and dyeing wastewater with poor water quality, the membrane fibers are not easily torn due to mud collection, and are not easy to break during air washing, backwashing, etc., and are not easy to peel off and be damaged, and have a long service life.

[0061] Working principle: During the operation of the device, cleaning liquid is first injected into the water supply tank 101 through the water inlet pipe 13. The cleaning liquid enters the inner cavity of the support column 11 through the absorption hole 704 on the suction ring tube 702 and is absorbed by the water supply pump 701. After being pressurized by the water supply pump 701, it is injected into the water supply pipe 8 connected to the water supply connector 703, and then enters the pressure valve 10 after passing through the water supply pipe 8. After being pressurized again by the pressure valve 10, it is sprayed out from the high-pressure nozzle 501. The sprayed cleaning liquid rinses the MCR membrane assembly 3 erected directly above the cleaning table 2 by the lifting equipment.

[0062] Since the MCR membrane components 3 are formed by splicing a plurality of MCR diaphragms 301 together, there are gaps between the MCR diaphragms 301. During flushing, the cleaning liquid can enter the interior of the MCR membrane components 3 through the gaps between the MCR diaphragms 301 for flushing. However, the flushing direction of the cleaning liquid entering through the gaps is often parallel to the MCR diaphragms 301, and the cleaning liquid cannot be completely flushed into the interior of the MCR membrane components 3. As a result, the flushing components 5 can only have a better flushing effect on the exterior of the MCR membrane components 3. Therefore, two groups of flushing components 5 are provided. During flushing, the two groups of flushing components 5 simultaneously flush the cleaning liquid into the gaps on both sides of the MCR membrane components 3. The flushing liquids in two opposite directions collide with each other inside the MCR membrane components 3 to generate convection, thereby changing the flushing direction of the cleaning liquid flushed into the interior of the MCR membrane components 3 and flushing in various directions inside the MCR membrane components 3, thereby achieving cleaning of the interior of the MCR membrane components 3.

[0063] During the flushing process, the flushing component 5 can move around the slide rail and rotate 360 ​​degrees around the MCR membrane component 3. Through flushing at multiple angles, in conjunction with the recognition camera 6 set on the mounting table 502, the stains on the MCR membrane component 3 can be quickly identified to determine whether the cleaning degree is up to standard. During the rotation of the flushing component 5, the liquid suction ring 702 also rotates with the flushing component 5, stirring the cleaning liquid and fully stirring and mixing the cleaning liquid.

[0064] The cleaning waste liquid dropped after cleaning is collected by the cleaning table 2, absorbed by the drain valve 9 and discharged into the drain tank 102, and discharged from the device through the outlet pipe 14, completing the entire cleaning process.
