[0002] High-efficiency sterilization filters are an indispensable device in pipelines transporting media. They are installed inside pressure reducing valves, pressure relief valves, and constant water level valves. High-efficiency sterilization filters consist of a cylindrical body, stainless steel filter screen, sewage discharge section, transmission device, and electrical control section.

[0003] Existing high-efficiency sterilization filters work by passing the water to be treated through the filter screen cartridge, where impurities are blocked. When cleaning is required, the detachable filter cartridge can be removed, cleaned, and then reinstalled. Therefore, it is convenient to use and maintain.

[0004] However, existing high-efficiency sterilization filters filter through filter screens, but after prolonged use, a lot of impurities accumulate on the surface of the filter screens. When a large amount of impurities adhere to the surface of the filter screens, the effective filtration area of ​​the filter screens will be reduced, thus affecting the filtration effect of the filtration device. Therefore, a high-efficiency sterilization filter is proposed to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 4This utility model provides an embodiment of a high-efficiency sterilization filter, comprising a filter tube 1 and a water pipe 2. A connecting pipe 3 is connected through the waist of the filter tube 1. The filter tube 1 and the connecting pipe 3 are made of stainless steel. A pipe cap 4 is threaded to the bottom of the connecting pipe 3. A rotating assembly 5 is provided inside the connecting pipe 3. A filter assembly 6 is directly provided on the inner wall of the filter tube 1. A limiting block 7 is fixedly connected to the center of the pipe cap 4. The rotating assembly 5 includes a fixing block 54 placed on the top side inside the connecting pipe 3 and on the top of the limiting block 7. A filter cylinder 51 is fixedly connected between the opposite sides of the two fixing blocks 54. Filter holes 52 are evenly opened on the surface of the filter cylinder 51. The impurity inlet 53 is connected to a rotating shaft 55 between two fixed blocks 54. A limiting groove 56 is opened on the bottom surface of the fixed block 54. A bushing 57 is fixedly connected to the surface of the rotating shaft 55. Scrapers 58 are evenly fixedly connected to the surface of the bushing 57. Brushes 59 are fixedly connected to the ends of the scrapers 58. The filter hole 52 is used for preliminary filtration of larger impurities in the water. The impurity inlet 53 is located inside the filter tube 1, and the diameter of the impurity inlet 53 is the same as the inner diameter of the filter tube 1. The limiting block 7 is slidably connected inside the limiting groove 56 and is used to limit the movement of the limiting block 7. The scraper 58 is located inside the filter cylinder 51 and is directly opposite the impurity inlet 53. The brushes 59 are in contact with the inner wall of the filter cylinder 51.

[0025] Reference Figure 1 - Figure 4 The filter assembly 6 includes a coarse filter screen 61 fixedly connected between the inner walls of the filter tubes 1, a fine filter screen 62 fixedly connected between the inner walls of the filter tubes 1 and to the right of the coarse filter screen 61, a high-efficiency filter element 63 fixedly connected between the inner walls of the filter tubes 1 and to the right of the fine filter screen 62, and an activated carbon filter element 64 fixedly connected between the inner walls of the filter tubes 1 and to the right of the high-efficiency filter element 63. The high-efficiency filter element 63 uses tubular filter elements such as polypropylene, polytetrafluoroethylene, and polyethersulfone as filter elements. The coarse filter screen 61 is used to filter larger impurities in the water flow, the fine filter screen 62 is used to filter smaller impurities in the water flow, the high-efficiency filter element 63 is used to remove microorganisms and bacteria in the water flow, and the activated carbon filter element 64 is used to adsorb odor molecules and pigments in the water to improve the taste of the water. In terms of appearance, activated carbon filter element 64 can adsorb residual chlorine and free chlorine in water, preventing them from causing oxidation and pollution to subsequent water treatment equipment. It also removes organic matter; the porous structure of activated carbon gives it a large specific surface area and adsorption capacity, effectively removing large molecular organic matter and humic acid from the water, reducing the pollution caused by organic matter. It also removes microorganisms and heavy metals, improving water quality. Activated carbon filters can be used as a pretreatment step to provide higher quality water for subsequent treatment, or as a deep treatment method after secondary treatment to further purify the water. The coarse filter screen 61 is located on the right side of the filter cartridge 51, and both ends of the filter tube 1 are fixedly connected to the water pipe 2.

[0026] Working principle: In use, first, fix both ends of the filter tube 1 to the water pipe 2 respectively. Then, turn on the water flow. The water flows into the filter tube 1 through the water pipe 2, passes through the impurity inlet 53 and the filter holes 52 for preliminary filtration of larger impurities in the water. The water flow impacts the scraper 58, which drives the rotating shaft 55 to rotate. The rotation of the scraper 58 drives the brush 59 to rotate. The brush 59 continuously washes the inner wall of the filter cylinder 51, effectively preventing larger impurities from clogging the filter holes 52 on the surface of the filter cylinder 51. Then, the water flows through the filter cylinder. The water flows to the coarse filter screen 61, and then to the fine filter screen 62. After further filtration by the fine filter screen 62, the water reaches the high-efficiency filter element 63, where bacteria and microorganisms in the water are sterilized. The water then flows to the activated carbon filter element 64, where it adsorbs residual and free chlorine, preventing them from oxidizing and polluting subsequent water treatment equipment. It also removes organic matter. The porous structure of activated carbon gives it a large specific surface area and adsorption capacity. The activated carbon filter effectively removes large molecular organic matter and humic acid from the water, reducing the pollution caused by organic matter in subsequent treatments. It also removes microorganisms and heavy metals, improving water quality. The activated carbon filter can be used as a pretreatment step to provide higher quality water for subsequent treatments, or as a deep treatment method after secondary treatment to further purify the water. Through the combined use of filter cartridge 51, coarse filter screen 61, fine filter screen 62, high-efficiency filter element 63, and activated carbon filter element 64, this high-efficiency antibacterial filter achieves multi-stage filtration, improving the quality of the filtered water while efficiently filtering and sterilizing it. When the filter cartridge 51 is full, the water flow from the water pipe 2 on the right side of the filter cartridge 51 is turned off. Then, the pipe cover 4 is opened and removed, freeing the filter cartridge 51 from its confinement. The filter cartridge 51 can then be removed for cleaning. Water flow can also flush out impurities from the surface of the coarse filter screen 61 through the connecting pipe 3. The process can then be reversed to reinstall the filter cartridge 51.
