Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a ceramic membrane filter with a flow guide plate. Background Technology

[0002] Ceramic membrane separation technology is a material separation technology based on the sieving effect of porous ceramic media. It adopts a dynamic "cross-flow filtration" method that is completely different from traditional filtration methods such as "dead-end filtration" and "filter cake filtration". Due to its high separation efficiency, no phase change, energy saving and environmental protection, simple equipment and easy operation, ceramic membrane filtration separation technology has considerable technical advantages in the field of water treatment and has become one of the indispensable technologies in the field of water treatment.

[0003] An existing ceramic membrane filter with a flow guide plate (publication number: CN222131514U) has at least the following drawbacks:

[0004] In the aforementioned document, when the guide rod rotates, the first scraper rotates around the guide rod as the center, scraping the outer surface of the ceramic membrane filter tube to prevent impurities from adhering for a long time and causing blockage of the filter pores, thus ensuring filtration efficiency. However, the impurities after scraping are not removed and continue to adhere and block the outer wall of the ceramic membrane filter tank as the liquid flows, affecting the filtration effect and having certain limitations. Therefore, it is necessary to propose a ceramic membrane filter with a guide plate to solve the above problems. Utility Model Content

A PLC controller is disposed on the outer circular wall of the tank body. The filter also includes a scraping assembly disposed on the inner circular wall of the tank body for scraping away impurities from the outside of the ceramic membrane filter tubes. The scraping assembly includes a sealing partition fixedly sleeved on the inner circular wall of the tank body.

[0026] Reference Figures 1-6A ceramic membrane filter with a guide plate includes a tank 1, inside which are arranged a plurality of ceramic membrane filter tubes 2. A PLC controller is arranged on the outer circular wall of the tank 1. It also includes a scraping assembly, disposed on the inner circular wall of the tank 1, for scraping impurities from the outside of the ceramic membrane filter tubes 2. The scraping assembly includes a sealing partition 3, which is fixedly sleeved on the inner circular wall of the tank 1. The bottom surface of the sealing partition 3 has a plurality of first circular through holes, which are fixedly sleeved with the ceramic membrane filter tubes 2. The top surface of the tank 1 has a plurality of second circular through holes, and a rotating chamber 5 is movably sleeved on the inner circular wall of the second circular through holes. The rotating chamber 5 is sleeved on the outside of the ceramic membrane filter tubes 2. There is a certain gap between the rotating chamber 5 and the ceramic membrane filter tube 2, allowing liquid to enter the interior through the outside of the ceramic membrane filter tube 2. A scraper plate 12 is fixedly installed on one side of the rotating chamber 5, and the scraper plate 12 is attached to the outer surface of the ceramic membrane filter tube 2. A gear 10 is fixedly sleeved on the outer circular wall of the rotating chamber 5. A drive motor 13 is provided on the top surface of the tank 1. A gear plate 15 is fixedly sleeved on the outer circular wall of the drive shaft of the drive motor 13, and the gear plate 15 meshes with the gear 10. A filter screen 21 and a suction assembly are fixedly installed inside the rotating chamber 5. The suction assembly is located on the top surface of the rotating chamber 5 and is used to suction the scraped impurities. A filtration assembly is located on the outer circular wall of the tank 1 and is used to filter out the impurities in the suctioned mixture.

[0027] In use, when filtering, the drive motor 13 is started to drive the gear disk 15 to rotate through the set tank 1. The rotating gear disk 15 drives the gear 10 and the rotating chamber 5 to rotate. The set bearing 4 supports the rotating chamber 5. At the same time, the set rotating chamber 5 drives the scraper plate 12 to scrape up the impurities filtered from the outside of the ceramic membrane filter tube 2, so that the impurities enter the interior of the rotating chamber 5 and pass through the set filter screen 21 to filter the impurities, thereby completing the removal of impurities.

[0028] In this embodiment, the suction assembly includes: a fixing hole 6, which is located on the top surface of the rotating chamber 5; a fixing tube 8 is movably fitted onto the inner circular wall of the fixing hole 6; a support hole 7 is provided on the top surface of the rotating chamber 5, and the fixing tube 8 is movably fitted onto the support hole 7; a plurality of suction holes 9 are provided on the outer circular wall of the fixing tube 8; a rotating elbow 11 is fixedly fitted onto the outer circular wall of the fixing tube 8; an annular connecting pipe 14 is provided on the top surface of the tank body 1, and the annular connecting pipe 14 is fixedly fitted onto the rotating elbow 11; and a suction pump 16 is fixedly installed on the top surface of the tank body 1. The inner circular wall of the inlet of the pump 16 is fixedly sleeved with the annular connecting pipe 14, and the inner circular wall of the outlet of the pump 16 is fixedly sleeved with the drain pipe 17. The filter assembly includes: a side chamber 18, which is fixedly installed on the outer circular wall of the tank 1. A third circular through hole is opened on the top surface of the side chamber 18, and the inner circular wall of the third circular through hole is fixedly sleeved with the drain pipe 17. A connecting hole 19 is opened on the outer circular wall of the tank 1 and one side of the side chamber 18, and a rectangular through hole is opened on one side of the side chamber 18. A filter chamber 20 is movably sleeved inside the rectangular through hole.

[0029] In use, the suction pump 16 is activated to draw air from the inside of the fixed pipe 8 through the annular connecting pipe 14 and the rotating elbow 11. This draws impurities filtered from the rotating chamber 5 through several suction holes 9. The impurities, mixed with liquid, enter the fixed pipe 8, the annular connecting pipe 14, and the suction pump 16, and are discharged through the drain pipe 17. Subsequently, a large amount of impurities and liquid mixed in the drain pipe 17 enters the side chamber 18 and falls into the filter chamber 20. The filter chamber 20 filters the impurities again, and the liquid flows downward to the bottom of the side chamber 18 and flows back into the tank 1 through the connecting hole 19. Furthermore, the filter chamber 20 can be removed from the side chamber 18 by pulling it, which facilitates the cleaning of impurities and makes it convenient to use.

[0030] In this embodiment, two support plates 22 are fixedly installed on the top surface of the tank 1. A fourth circular through hole is opened on one side of the support plate 22. The fourth circular through hole is fixedly sleeved with the annular connecting pipe 14. The support plate 22 is fixedly installed with the drive motor 13. The support plate 22 is fixedly installed on the outer circular wall of the tank 1. The support plate 22 is fixedly installed with the PLC controller. The bearing 4 is fixedly sleeved on the outer circular wall of the rotating chamber 5. The bearing 4 is fixedly sleeved with the second circular through hole.

[0031] In use, the drive motor 13 and the annular connecting pipe 14 are supported and fixed by the support plate 22 to ensure the operation of the device.

[0032] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0033] When the user needs to use the tank 1, liquid enters through the top inlet pipe, submerging several ceramic membrane filter tubes 2. These tubes filter the liquid, allowing it to pass through the filter holes (a gap exists between the rotating chamber 5 and the ceramic membrane filter tubes 2, allowing liquid to pass through the outside of the tubes). The filtered liquid then flows to the bottom of the tank 1 and is finally discharged through the bottom pipe. During filtration, the drive motor 13 rotates the geared disc 15, which in turn drives the gears. The rotating chamber 5 and the rotating chamber 10 rotate, supported by the bearing 4. Simultaneously, the rotating chamber 5 drives the scraper 12 to scrape up impurities filtered from the outside of the ceramic membrane filter tube 2. The scraper 12 has a certain inclination, allowing it to approach the outer wall of the ceramic membrane filter tube 2 as closely as possible, enabling the impurities to enter the interior of the rotating chamber 5 and pass through the filter screen 21 for filtration, thus completing the removal of impurities. Then, the suction pump 16 is activated, sucking the contents of the fixed tube 8 through the annular connecting pipe 14 and the rotating elbow 11. As the rotating chamber 5 rotates, causing the fixed tube 8 to rotate slowly, the rotating elbow 11... The fixed pipe 8 and the annular connecting pipe 14 are connected, thereby drawing in impurities filtered from inside the rotating chamber 5 through several suction holes 9. Impurities mixed with liquid enter the fixed pipe 8, and then through the rotating elbow 11 into the annular connecting pipe 14 and the suction pump 16, before being discharged through the drain pipe 17. This completes the suction and cleaning of impurities. Subsequently, a large amount of impurities and liquid mixed inside the drain pipe 17 enters the side chamber 18 and falls into the filter chamber 20. The filter chamber 20 filters the impurities again, and the liquid flows downwards to the bottom of the side chamber 18, flowing back into the tank 1 through the connecting hole 19. Furthermore, by pulling the filter chamber 20, the liquid can be drawn from... The side chamber 18 can be removed from the inside, making it convenient to clean impurities and improve usability. Through the coordinated use of the tank body 1, ceramic membrane filter tube 2, sealing partition 3, bearing 4, rotating chamber 5, fixing hole 6, and support hole 7, the exterior of the ceramic membrane filter tube 2 can be scraped and sucked clean. After the impurities are scraped off, they enter the interior of the rotating chamber 5 and, along with the sucked water flow, enter the interior of the fixing pipe 8, annular connecting pipe 14, and suction pump 16. The external filter chamber 20 filters out the impurities, making cleaning convenient. The filtered liquid continues to flow back into the interior of the tank body 1, effectively avoiding the problem of impurities being scraped off but not cleaned. This makes it convenient and practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
