Description

Technical Field

[0001] The invention relates to the field of ultrafiltration membrane filtration, in particular to a filtration system and process based on ultrafiltration membrane purification. Background Art

[0002] Ultrafiltration membrane is used as an artificial permeable membrane in the ultrafiltration process. It is generally made of polymer materials such as cellulose acetate, cellulose acetate ester, polyethylene, polysulfone and polyamide. It is generally pre-made into various types of membrane components such as tubular, plate, roll, capillary, etc., and then multiple components are assembled together for use to increase the filtration area and facilitate maintenance. Ultrafiltration membrane is a polymer semi-permeable membrane used in the ultrafiltration process that can separate polymer colloids or suspended particles of a certain size from the solution.

[0003] After searching, Chinese patent number CN216236340U discloses an ultrafiltration membrane filtration device for water purification, including a filter shell, a water inlet pipe, a drain pipe, a sealing mechanism, a threaded connection mechanism, an L-shaped scraper, a transmission mechanism and an operating handle. The filter shell is a shell with a closed top and an open bottom, and the sealing mechanism is arranged at the bottom of the filter shell. One end of the water inlet pipe is connected to the top of the filter shell, and one end of the drain pipe is connected to the side wall of the filter shell. The filter cartridge is arranged inside the filter shell, and an ultrafiltration membrane is fixedly arranged on the inner wall of the filter cartridge. The transmission mechanism is arranged on the sealing mechanism, and the L-shaped scraper is located inside the filter cartridge. The transmission mechanism is fixedly connected to the L-shaped scraper, and the operating handle can drive the L-shaped scraper to rotate through the transmission mechanism. The attachments on the ultrafiltration membrane can be scraped off by rotating the L-shaped scraper, thereby improving the filtration rate of the ultrafiltration membrane. Impurities attached to the ultrafiltration membrane can be removed without disassembly, ensuring the filtration effect and water discharge efficiency of the ultrafiltration membrane, and greatly reducing the frequency of disassembly and cleaning.

[0004] However, there are the following problems in the above prior art:

[0005] Although the shaft can be rotated by rotating the operating handle to realize the rotation of the L-shaped scraper, the attachments on the ultrafiltration membrane can be scraped off by rotating the L-shaped scraper, thereby ensuring the filtering effect and water output efficiency of the ultrafiltration membrane and reducing the frequency of its disassembly and cleaning. However, after the ultrafiltration membrane is cleaned by the L-shaped scraper, the cleaned debris cannot be discharged, which will cause secondary clogging of the ultrafiltration membrane, thereby requiring manual cleaning of the debris. Therefore, the filtration system of the ultrafiltration membrane purification needs to be shut down, thereby reducing the filtration efficiency of the ultrafiltration membrane purification filtration system.

The larger particles in the material are filtered through the setting of the sand filter cartridge. Then, the filtered material enters the carbon filter cartridge through the connecting pipe to further filter the material. Finally, the material that has been filtered twice enters the interior of the hose through the feed pipe;

[0023] S5. When debris enters the collection box, the first bevel gear drives the second bevel gear to mesh and rotate through the setting of the cleaning motor, so that the rotating ring rotates synchronously, driving the cleaning plate to rotate inside the collection box, cleaning the inside of the collection box, thereby cleaning the debris through the sewage trough to the inside of the conical hollow block, completing automatic sewage discharge.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. Through the arrangement of the first filtering mechanism, the second filtering mechanism, the cleaning mechanism, the scraping mechanism and the drainage mechanism, the material is discharged into the first filtering mechanism, the material is filtered twice, and then the filtered material is discharged into the interior of the hollow disk through the hose, so that the material enters the interior of the ultrafiltration membrane purification cylinder through the arrangement of the feed hole, and the material is filtered based on the ultrafiltration membrane. At the same time, through the mutual cooperation of the ultrafiltration membrane purification cylinder and the drainage mechanism, the filtered material enters the interior of the filter cylinder from the ultrafiltration membrane purification cylinder, and through the arrangement of the plug-in tube, the filtered material enters the interior of the connecting tube, and through the arrangement of the drainage pipe, the material that has been filtered multiple times is discharged, thereby completing the filtration of the material. Through multiple filtrations, the material to be filtered is filtered more thoroughly;

[0026] 2. Through the arrangement of the first filtering mechanism, the second filtering mechanism, the cleaning mechanism, the scraping mechanism and the drainage mechanism, during the use of the ultrafiltration membrane purification cartridge, the scraping motor is started to rotate the threaded rod, so that the moving block slides inside the ultrafiltration membrane purification cartridge through the arrangement of the limit rod, and the inner arc surface of the ultrafiltration membrane purification cartridge is scraped by the scraping base, thereby avoiding the clogging of the ultrafiltration membrane purification cartridge by debris due to long-term use, thereby affecting the filtration of the material, and through the mutual cooperation of the arc-shaped pushing plate and the scraping base, the scraped debris is collected in the space between the arc-shaped pushing plate and the ultrafiltration membrane purification cartridge, thereby avoiding the cleaned debris from falling back into the ultrafiltration membrane purification cartridge, thereby causing a secondary impact on the ultrafiltration membrane purification cartridge;

[0027] 3. Through the arrangement of the first filtering mechanism, the second filtering mechanism, the cleaning mechanism, the scraping mechanism and the drainage mechanism, the cleaned debris is moved to the inside of the hollow box through the arrangement of the scraping mechanism, so that the arc-shaped push plate fits with the arc-shaped plate, and through the arrangement of the arc-shaped plate, the arc-shaped push plate pushes the debris to fall into the inside of the collection box, and the cleaning motor is started, so that the first bevel gear drives the second bevel gear to mesh and rotate, so that the rotating ring rotates, driving the cleaning plate inside the collection box, thereby pushing the debris inside the collection box through the sewage trough into the inside of the conical hollow block, and through the arrangement of the placement ring, the debris entering the conical hollow block enters the inside of the placement ring, completing the automatic cleaning of the debris, thereby avoiding manual cleaning of the debris inside the collection box, and improving the filtration efficiency of the ultrafiltration membrane purification filtration system;

[0028] 4. Through the arrangement of the first filtering mechanism, the second filtering mechanism, the cleaning mechanism, the scraping mechanism and the drainage mechanism, the material to be filtered is discharged into the interior of the sand filter cartridge through the feed pipe. Through the arrangement of the sand filter cartridge, the material is filtered once, and then the filtered material is discharged into the interior of the carbon filter cartridge through the connecting pipe. After the material is filtered for the second time, it is discharged into the interior of the hose through the feed pipe, thereby filtering out larger impurities in the material, preventing the material from directly entering the interior of the ultrafiltration membrane purification cartridge, causing larger impurities to affect the ultrafiltration membrane purification cartridge, thereby preventing larger impurities from damaging the ultrafiltration membrane purification cartridge, reducing the replacement of the ultrafiltration membrane purification cartridge by the staff, and improving the efficiency of the ultrafiltration membrane purification system during use.

The moving plate 701 synchronously enters the interior of the hollow box 105, so that the arc-shaped push plate 701 fits with the arc-shaped plate 11, so that the arc-shaped push plate 701 moves on the scraping base 405, and pushes the debris on the scraping base 405 into the interior of the collecting box 501, so that the debris is automatically discharged through the setting of the cleaning mechanism 5, avoiding the manual cleaning of the debris by the staff, thereby improving the filtration efficiency of the ultrafiltration membrane filtration system, and at the same time, through the setting of the pushing rod 702 and the reset spring 703, when the arc-shaped push plate 701 is separated from the arc-shaped plate 11, the elastic force of the reset spring 703 makes the arc-shaped push plate 701 automatically reset, thereby facilitating the secondary use of the arc-shaped push plate 701, and through the setting of the pushing rod 702, the arc-shaped push plate 701 is more stable when moving;

[0056] In combination with the above-mentioned filtration system based on ultrafiltration membrane purification, a process of a filtration system based on ultrafiltration membrane purification is provided, which specifically includes the following steps:

[0057] S1. The material to be filtered is discharged into the sand filter cartridge 201 through the feed pipe 204. The larger particles in the material are filtered through the setting of the sand filter cartridge 201. Then, the filtered material enters the carbon filter cartridge 203 through the connecting pipe 202, and the material is further filtered. Finally, the material after two filtrations enters the interior of the hose 302 through the feed pipe 205;

[0058] S2, when the material enters the interior of the hose 302, the material enters the interior of the hollow disk 301, and then enters the interior of the ultrafiltration membrane purification cylinder 306 through the setting of the feed hole 303, so that the material is squeezed out of the ultrafiltration membrane purification cylinder 306, and the material is filtered, and then the filtered material is discharged from the filter cylinder 102 through the setting of the drainage mechanism 6;

[0059] S3. When the ultrafiltration membrane purification cartridge 306 is in use, the scraping motor 401 is set so that the threaded rod 402 drives the moving block 403 to slide inside the ultrafiltration membrane purification cartridge 306, thereby driving the scraping base 405 to slide on the inner arc surface of the ultrafiltration membrane purification cartridge 306 to scrape the inner arc surface. At the same time, the arc-shaped push plate 701 is set so that the scraped debris is collected in the space between the arc-shaped push plate 701 and the ultrafiltration membrane purification cartridge 306.

[0060] S4, by rotating the threaded rod 402, the scraper base 405 is moved to the inside of the hollow box 105, and by setting the arc plate 11, the arc push plate 701 slides on the surface of the scraper base 405, thereby pushing the debris on the scraper base 405 to move, so that the debris moves to the inside of the collection box 501, and the debris inside the ultrafiltration membrane purification cylinder 306 is cleaned;

[0061] S5. When debris enters the collection box 501, the first bevel gear 504 drives the second bevel gear 505 to mesh and rotate through the setting of the cleaning motor 502, so that the rotating ring 506 rotates synchronously, driving the cleaning plate 509 to rotate inside the collection box 501, cleaning the inside of the collection box 501, thereby cleaning the debris through the drainage trough 507 to the inside of the conical hollow block 508, completing automatic drainage.

[0062] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
