DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] like Figure 1-Figure 4As shown, a ceramic membrane filter with a guide plate proposed in one embodiment of the present application comprises: a tank body 1, one side of which is connected to a water inlet pipe 2, and the bottom of which is connected to a sewage pipe 3; a ring pipe 4, which is coaxially arranged at the inner bottom of the tank body 1, and is connected to a drainage pipe 5 whose end extends to the outside of the tank body 1, and the top of the ring pipe 4 is connected to a plurality of ceramic membrane filter tubes 6 distributed in an annular manner. Preferably, the top of the ceramic membrane filter tube 6 is a closed structure, and the top of the ceramic membrane filter tube 6 is rotatably connected to a guide rod 7, and two first scrapers 8 are symmetrically arranged on the guide rod 7. The two first The scrapers 8 are all overlapped with the outer surface of the ceramic membrane filter tube 6; the driving mechanism 9 is arranged on the tank body 1, and is used to drive the plurality of guide rods 7 to rotate synchronously. When filtering, the liquid enters the tank body 1 from the water inlet pipe 2, and the liquid submerges the plurality of ceramic membrane filter tubes 6. The plurality of ceramic membrane filter tubes 6 filter the liquid. The liquid allowed to pass through the filtration passes through the filter holes of the ceramic membrane filter tube 6 into the interior of the ceramic membrane filter tube 6. The filtered liquid then converges into the ring tube 4 and is finally discharged through the drain pipe 5. When filtering, the driving mechanism 9 drives the plurality of guide rods 7 When the guide rod 7 rotates, the first scraper 8 rotates with the guide rod 7 as the center, thereby scraping the outer surface of the ceramic membrane filter tube 6 to prevent impurities from adhering for a long time and causing clogging of the filter holes, thereby ensuring the filtration efficiency. The liquid and impurities that are not allowed to pass through after filtration remain in the tank body 1 and are then discharged through the sewage pipe 3. When the liquid filtration is completed and the ceramic membrane filter tube 6 needs to be cleaned, the cleaning liquid is transported from the drainage pipe 5 to the ring pipe 4, and then transported to the inside of several ceramic membrane filter tubes 6 through the ring pipe 4. The cleaning liquid is then discharged from the filter of the ceramic membrane filter tube 6. The holes flow outward. At this time, when cleaning, the driving mechanism 9 is opened again, so that the first scraper 8 scrapes the outer surface of the ceramic membrane filter tube 6, and the inner surface of the ceramic membrane filter tube 6 is cleaned with the outflowing cleaning liquid. Several ceramic membrane filter tubes 6 are connected to the ring tube 4, and the outer surface of the ceramic membrane filter tube 6 is scraped by the first scraper 8. Not only can the outer surfaces of several ceramic membrane filter tubes 6 be scraped during filtration to prevent the filter holes from being easily covered and blocked by impurities, but also the cleaning effect can be improved during backwashing, thereby improving practicality.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the driving mechanism 9 includes a rotating shaft 901 that coaxially rotates and passes through the inner top wall of the tank body 1, the top of the rotating shaft 901 is connected to a motor 902 fixed on the tank body 1, and several guide rods 7 are fixed with gears 903. The rotating shaft 901 is connected to a gear ring 904 through a support rod, and several gears 903 are meshed with the teeth of the gear ring 904. When the motor 902 does work, its output shaft drives the rotating shaft 901 to rotate, and the rotating shaft 901 drives the gear ring 904 to rotate through the support rod. The teeth of the gear ring 904 and the several gears 903 are meshed, thereby driving the several guide rods 7 to rotate synchronously, so that the outer surfaces of several ceramic membrane filter tubes 6 can be scraped.

[0027] like Figure 3 As shown, in some embodiments, a support ring 10 is connected to the rotating shaft 901 through a support rod, and a movable ring 11 is rotatably sleeved on the support ring 10, and several guide rods 7 are rotatably penetrated through the movable ring 11. Since the ceramic membrane filter tube 6 has a certain length and only the bottom end is connected to the ring tube 4, it is easy to be shaken by the stress of the liquid during filtration. By setting the support ring 10, the movable ring 11 is rotatably set on the support ring 10, and the guide rods 7 are rotatably penetrated through the movable ring 11, thereby indirectly supporting the top end of the ceramic membrane filter tube 6, so that both ends of the ceramic membrane filter tube 6 have support points, while also ensuring the stability of the meshing of the tooth ring 904 with the gear 903.

[0028] like Figure 2 As shown, in some embodiments, two second scrapers 12 are symmetrically arranged on the outer surface of the rotating shaft 901, and the two second scrapers 12 are overlapped with the inner wall of the tank body 1. By arranging the second scraper 12 on the outer surface of the rotating shaft 901, when the rotating shaft 901 rotates, the second scraper 12 scrapes the inner wall of the tank body 1 to prevent impurities from adhering to the inner wall of the tank body 1. At the same time, during backwashing, the cleaning liquid sprayed from the filter holes of the ceramic membrane filter tube 6 can better clean the inner wall of the tank body 1, thereby improving the overall cleaning effect of the filter.

[0029] like Figure 2 As shown, in some embodiments, the inner bottom wall of the tank body 1 is in a conical structure, the sewage pipe 3 is connected to the tip of the cone, and the ring tube 4 is arranged on the inner wall of the tank body 1 through a support rod. By making the bottom of the tank body 1 in a conical structure and the sewage pipe 3 connected to the conical end, impurities can be effectively discharged. The ring tube 4 is arranged on the inner wall of the tank body 1 through a support rod, so that the ring tube 4 is not in direct contact with the inner bottom wall of the tank body 1, and a sediment chamber is formed under the ring tube 4 to facilitate the deposition of impurities, avoiding excessive impurities directly covering the ring tube 4 and causing blockage of the filter holes at the lower end of the ceramic membrane filter tube 6, and also preventing the ring tube 4 from blocking the discharge of impurities, thereby improving practicality.

[0030] like Figure 2As shown, in some embodiments, two third scrapers 13 are symmetrically arranged on the outer surface of the rotating shaft 901, and the two third scrapers 13 are overlapped with the inner bottom wall of the tank body 1. When the rotating shaft 901 rotates, the third scraper 13 scrapes the inner wall of the conical bottom end of the tank body 1, so that the impurities can be effectively discharged when the impurities are discharged. At the same time, it is also convenient to scrape the inner wall of the sediment chamber, thereby improving the overall cleaning effect of the filter.

[0031] like Figure 3 and Figure 4 As shown, in some embodiments, a rotating rod 14 is coaxially rotated through the inner top wall of the ceramic membrane filter tube 6, and the rotating rod 14 is fixedly connected to the guide rod 7. A spiral guide plate 15 is provided on the outer surface of the rotating rod 14, and the outer edge of the spiral guide plate 15 overlaps the inner wall of the ceramic membrane filter tube 6. When the ceramic membrane filter tube 6 is backwashed, the rotating rod 14 rotates, thereby driving the spiral guide plate 15 to rotate. When the spiral guide plate 15 rotates, it is not only convenient to quickly lift the cleaning liquid, thereby effectively cleaning the ceramic membrane filter tube 6 as a whole, but also, when the spiral guide plate 15 rotates, it can also scrape the inner wall of the ceramic membrane filter tube 6 to further improve the cleaning effect.

[0032] like Figure 2 As shown, in some embodiments, a plurality of stirring blades 16 are arranged in an array on the outer surface of the rotating shaft 901. Through the stirring blades 16, when filtering the liquid, the rotating shaft 901 drives the stirring blades 16 to stir the liquid, so that the fluidity of the liquid is better. Under the effect of fluidity, impurities are less likely to adhere to the surface of the ceramic membrane filter tube 6, thereby improving the filtering effect. At the same time, during backwashing, the cleaning liquid sprayed from the ceramic membrane filter tube 6 will be impacted by the stirring blades 16, so that the cleaning liquid will be splashed on the surface of the ceramic membrane filter tube 6 or the inner wall of the tank body 1 under the impact, thereby improving the cleaning effect of the filter as a whole.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
