Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a membrane module cleaning and antifouling structure. Background Technology

[0002] Membrane modules are the core components of membrane separation technology. They achieve efficient separation, concentration, or purification of substances through selective permeation of the membrane and are widely used in water treatment, food, pharmaceuticals, chemicals, energy, and other fields. They are one of the key technologies for achieving green and efficient separation. During long-term use, membrane modules can become fouled by impurities and require regular cleaning to ensure their filtration efficiency.

[0003] Existing membrane module cleaning and antifouling structures typically employ two methods for cleaning: manual high-pressure water gun rinsing and automatic nozzle rinsing. While nozzle rinsing allows for reverse cleaning of the membrane module and removal of dirt from its exterior, the fixed nozzles limit the rinsing range, making it difficult to cover the edges and complex structural areas of the membrane module, easily creating cleaning dead zones. Furthermore, water rinsing alone may not be sufficient to remove dirt, thus reducing the cleaning effect. To extend the membrane module's lifespan, pretreatment mechanisms are installed at the inlet to remove suspended solids, colloids, and other large particulate impurities from the water using filter plates, reducing the risk of membrane fouling. However, filter plates have a limited lifespan and require periodic replacement. Typically, filter plates are installed inside the device with screws, requiring tools to remove the screws and loosen their position during replacement, a cumbersome process that reduces the efficiency of membrane module maintenance.

[0032] A treatment tank 1 is set up to install the membrane body 12, and an outlet pipe is connected to the other side of the tank to transport the treated water to the next process. A lifting assembly 4 is set up, which consists of an electric telescopic rod and a fixed rod. The electric telescopic rod is used to drive the support frame 5 to move up and down, so that the flushing assembly 9 can be detached from the treatment tank 1 when it is not working. The fixed rod is slidably connected to the support frame 5 to improve the stability of the movement of the support frame 5. The membrane body 12 is set up to intercept impurities in the water.

[0036] By setting up filter plate 13 as the first filtration barrier, large particulate impurities are intercepted, protecting the subsequent membrane body 12 from clogging.

[0037] Example 2:

[0038] Reference Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the drive assembly 6 includes a motor 61 fixed to the top of the support frame 5. The output end of the motor 61 is provided with a screw 62. A threaded sleeve 63 is threadedly connected to the outer side of the screw 62. The outer side of the threaded sleeve 63 is fixedly connected to the top of the connecting plate 7.

[0040] When the motor 61 drives the screw 62 to rotate, it will cause the threaded sleeve 63, which is threaded to the outside of the screw 62, to move in parallel.

[0041] Specifically, the guide assembly 8 includes a sliding block 81 fixed to the top of the connecting plate 7, and a guide rod 82 slidably connected to the inner wall of the sliding block 81. The two ends of the guide rod 82 are respectively fixedly connected to the outer sides of the two support frames 5.

[0042] When the support frame 5 moves with the threaded sleeve 63, the sliding blocks 81 connected at both ends of it will slide along the guide rod 82, so that the support frame 5 moves along the set route, which improves the stability of the movement of the support frame 5.

[0043] Specifically, the flushing assembly 9 includes a connecting pipe 91 fixed to the outside of the connecting plate 7, and multiple nozzles 92 are provided on the outside of the connecting pipe 91.

[0044] The connecting pipe 91 is made of flexible hose and has sufficient length to move with the connecting plate 7. The connecting pipe 91 has multiple branches that are connected to the nozzles 92. The multiple nozzles 92 have different connection angles with the connecting pipe 91, so that when the nozzles 92 spray water, they can cover the membrane body 12 in all directions and improve the cleaning effect.

[0045] Specifically, the sewage discharge assembly 11 includes a conveying pipe 111 located at the bottom of the treatment tank 1, and a sewage pump 112 is installed at one end of the conveying pipe 111.

[0046] The sewage pump 112 is fixedly installed at the bottom of the treatment tank 1 via a connector. When cleaning the membrane assembly, the sewage pump 112 is started and the cleaning sewage inside the treatment tank 1 is pumped out through the delivery pipe 111 connected to the pumping end and discharged to the outside through the outlet end.

[0047] Example 3:

[0048] Reference Figure 1 , Figure 5 and Figure 6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0049] Specifically, the sealing assembly 14 includes a cover plate 141 that engages with the top of the housing 2, and a sealing gasket 142 is installed at the bottom of the cover plate 141.

[0050] The cover plate 141 is used to seal the outer shell 2. At the same time, the cover plate 141 is in contact with the top of the filter plate 13. After the cover plate 141 is fixed to the top of the outer shell 2, it will limit the filter plate 13. The sealing gasket 142 is made of rubber and is used to prevent water leakage at the connection between the cover plate 141 and the outer shell 2.

[0051] Specifically, the adjustment assembly 17 includes a movable rod 171 that slides inside the fixed base 15, a fixed block 172 that is fixedly connected to the outside of the movable rod 171, and a spring 173 that is sleeved on the outside of the movable rod 171.

[0052] When the fixed block 172 loses its limit, the spring 173 will push the fixed block 172 and the moving rod 171 toward the limit groove 182 by the accumulated elastic force.

[0053] Specifically, the limiting component 18 includes a locking block 181 fixed to one end of the moving rod 171, a limiting groove 182 is formed on the inner side of the connecting block 16, and the outer side of the locking block 181 is slidably connected to the inner wall of the limiting groove 182.

[0054] When the locking block 181 enters the inner side of the limiting groove 182, it will cause the cover plate 141 to form a fixed connection with the outer shell 2, so that the filter plate 13 can be installed.

[0055] Specifically, the moving component 19 includes a lever 191 fixed to the top of the fixed block 172, and a guide groove 192 is provided on the top of the fixed base 15. The outer side of the lever 191 is slidably connected to the inner wall of the guide groove 192.

[0056] The lever 191 is used to pull the moving rod 171 to move, and the guide groove 192 restricts the moving path of the lever 191 to improve its moving stability.

[0057] During use, when cleaning the membrane body 12, the lifting assembly 4 first moves the support frame 5 downwards. After reaching the designated height, the water supply system pressurizes clean water and delivers it to the nozzles 92 via the connecting pipe 91. Multiple nozzles 92 then spray high-pressure water jets to backwash the membrane body 12. Simultaneously, the motor 61 drives the screw 62 to rotate, causing the threaded sleeve 63 to move the connecting plate 7 axially along the screw 62. The nozzles 92 and scraper 10 move synchronously with the connecting plate 7. Through continuous movement, the nozzles 92 can... The membrane body 12 can be rinsed at the edges and corners, while the scraper 10 scrapes away stubborn contaminants on the surface of the membrane body 12, improving the cleaning effect of the membrane module. When the filter plate 13 needs to be replaced, first pull the lever 191 to move to one side, compress the spring 173 through the fixing block 172, and at the same time move the moving rod 171 to move, so that the locking block 181 is disengaged from the inner side of the limiting groove 182, so that the cover plate 141 loses its limit. After lifting it upward, the filter plate 13 inside the outer shell 2 can be taken out to complete the disassembly.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
