Description

Technical Field

[0001] The utility model relates to the technical field of reclaimed water reuse, in particular to a reclaimed water reuse ultrafiltration device. Background Art

[0002] Recycled water reuse refers to the centralized treatment of residential waste (sewage) water (bathing, washing, laundry, kitchen, toilet) to meet certain standards and then reuse it for greening irrigation, vehicle washing, road washing, household toilet washing, etc. in the community, so as to achieve the purpose of saving water; Ultrafiltration is a common treatment method for recycled water reuse. Ultrafiltration is a membrane separation technology driven by pressure, with the purpose of separating macromolecules from small molecules, and the membrane pore size is between 20-1000A°; Ultrafiltration technology has the advantages of simple operation, low cost, and no need to add any chemical reagents. In particular, the experimental conditions of ultrafiltration technology are mild, there is no phase change compared with evaporation and freeze drying, and it does not cause changes in temperature and pH, which can prevent the denaturation, inactivation and autolysis of biological macromolecules;

[0003] However, common ultrafiltration devices on the market cannot achieve self-cleaning, which affects the filtering effect after long-term use, and cannot provide stable pressure inside the device, and it is not convenient to remove the cleaned impurities;

[0004] An existing patent (publication number: CN 213738726U) discloses a self-cleaning ultrafiltration device for recycling reclaimed water. A fixed plate and a threaded rod are provided. During the self-cleaning process, the fixed plate with a hole-shaped structure inside blocks the cleaned impurities below it, and the second motor is started. Under the rotation of the threaded rod, the push plate moves to the left, thereby facilitating the collection of impurities floating below the fixed plate into the interior of the storage box through a conveying pipe, thereby facilitating the removal of the cleaned impurities.

[0005] However, the above technical solution still has certain defects. The above device starts to backwash the device by inputting cleaning liquid into the interior of the ultrafiltration box, and flushes out the impurities deposited inside the ultrafiltration box. During this process, some scaling impurities may be firmly attached to the filter membrane and the inner wall of the ultrafiltration box, and are not easy to be flushed out, resulting in poor cleaning effect and affecting subsequent use. For this reason, a reclaimed water reuse ultrafiltration device is proposed. Utility Model Content

A rotating shaft 390 is provided at the center of the rotating shaft 390, and the rotating shaft 390 is connected to the fixed frame 380 through a bearing. A gear 3910 is fixedly connected to one end of the rotating shaft 390 located above the fixed frame 380, and the gear 3910 is meshed with the rack 370. A mounting seat 3920 is fixedly connected to the other end of the rotating shaft 390. Scrapers 3930 are fixedly installed on both sides of the upper end of the mounting seat 3920. The scrapers 3930 are in contact with the inner wall of the ultrafiltration box body 100, and a scraper strip 3940 is installed at the bottom of the mounting seat 3920. The scraper strip 3940 fits with the upper surface of the filter membrane 150, the length and width of the push plate 330 are greater than the length and width of the delivery pipe 340, and the push plate 330 and the delivery pipe 340 form a closed structure, a liquid inlet pipe 130 is installed on one side of the top of the fixed box 310, a liquid outlet pipe 140 is fixedly installed on the bottom of the ultrafiltration box body 100, a backwash pipe 3950 is installed on one side of the liquid outlet pipe 140, and the other end of the backwash pipe 3950 is connected to the water delivery pipe, and solenoid valves are provided inside the liquid inlet pipe 130, the liquid outlet pipe 140 and the water delivery pipe.

Under the action of the output end of the second electric push rod 320, the push plate 330 is pushed to move to one side, so that the impurities floating inside the fixed box 310 can be collected into the storage box 350 through the delivery pipe 340, so as to facilitate the removal of the cleaned impurities. At the same time, when When the push plate 330 passes the gear 3910, the L-shaped connecting rod 360 fixed to the push plate 330 and the rack 370 fixed on one side mesh with the gear 3910, thereby driving the gear 3910 to rotate, driving the rotating shaft 390 and the mounting seat 3920 fixed at the bottom end of the rotating shaft 390 to rotate together, and then driving the two sets of scrapers 3930 and the scraper strips 3940 to rotate, the scrapers 3930 scrape the inner wall of the ultrafiltration box body 100, and the scraper strips 3940 scrape the upper surface of the filter membrane 150, so that some scales that are relatively firmly attached to the surface of the filter membrane 150 and the inner wall of the ultrafiltration box body 100 are cleaned up, and cooperated with the push plate 330 to push all the scales into the interior of the storage box 350, thereby improving the cleaning effect.

Under the action of the output end of the second electric push rod 320, the push plate 330 is pushed to move to one side, so that the impurities floating inside the fixed box 310 can be collected into the interior of the storage box 350 through the delivery pipe 340, so as to facilitate the removal of the cleaned impurities. At the same time, when the push plate 330 passes through the gear 3910, it is fixed with the push plate 330. The fixed L-shaped connecting rod 360 and the rack 370 fixed on one side are meshed with the gear 3910, thereby driving the gear 3910 to rotate, driving the rotating shaft 390 and the mounting seat 3920 fixed at the bottom end of the rotating shaft 390 to rotate together, and then driving the two sets of scrapers 3930 and the scraper strips 3940 to rotate, the scrapers 3930 scrape the inner wall of the ultrafiltration box body 100, and the scraper strips 3940 scrape the upper surface of the filter membrane 150, so that some scales that are relatively firmly attached to the surface of the filter membrane 150 and the inner wall of the ultrafiltration box body 100 are cleaned up, and the push plate 330 is used to push all the scales into the interior of the storage box 350, thereby improving the cleaning effect.
