Description

Technical Field

[0001] This utility model belongs to the field of filter element technology, and in particular relates to an activated carbon composite filter element. Background Technology

[0002] Activated carbon composite filter cartridges are a type of composite filter cartridge that combines activated carbon with other filter materials. They are designed to perform multiple filtration effects simultaneously and are widely used in water treatment, air purification, automobiles, home appliances and other equipment. The core principle is to add activated carbon material to the main filtration layer of the filter cartridge. Activated carbon has a strong adsorption capacity and can effectively remove odors, harmful gases, chemical pollutants, heavy metal ions and other substances from water or air.

[0003] Existing activated carbon composite filter cartridges still have some problems during use. For example, during liquid filtration, large impurities in the liquid can easily adhere to the surface of the filter pores, causing the filtration effect to gradually decrease. These large impurities accumulate on the filter surface, hindering the normal flow of liquid and forcing users to frequently disassemble the filter cartridge for cleaning or replacement, thus affecting the normal use of the equipment. At the same time, as the filter cartridge is used for a longer period of time, the deposition of impurities not only leads to a decrease in filtration efficiency, but may also cause the physical structure of the filter cartridge to become rigid, or even jam, making it more difficult to clean and replace the filter cartridge, increasing inconvenience during use, and affecting the long-term operational stability of the equipment.

[0004] To address these issues, we provide an activated carbon composite filter element. Utility Model Content

[0005] The purpose of this invention is to provide an activated carbon composite filter element that, through the cooperation of a self-cleaning component and a sealing component, solves the problems of existing activated carbon composite filter elements, such as the need for frequent replacement and cleaning, and the tendency for the filter element to become stuck.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an activated carbon composite filter element, comprising a filter cartridge with a top cover at the top and a partition cylinder fixedly connected to the inner cavity of the filter cartridge. A self-cleaning assembly is provided at the bottom of the top cover, comprising a filter fixedly connected to the bottom of the top cover, a rotating impeller movably connected to the inner cavity of the filter, a scraping ring movably connected to the inner cavity of the filter, and scrapers on both sides of the top of the scraping ring. The self-cleaning assembly is used to scrape away impurities on the inner wall of the filter. A sealing assembly is provided in the inner cavity of the partition cylinder, comprising a preload spring fixedly connected to the bottom of the partition cylinder, a pressure plate fixedly connected to one end of the preload spring, and a compression block fixedly connected to the bottom of the filter. The sealing assembly is used to improve the sealing performance between the filter cartridge and the top cover.

[0008] The present invention is further configured such that a sintered metal mesh is fixedly connected to the inner wall of the filter, and an activated carbon filter layer is fixedly connected to one side of the sintered metal mesh, and the inner wall of the filter is composed of a composite of the sintered metal mesh and the activated carbon filter layer.

[0009] The present invention is further configured such that an ultrafiltration membrane is fixedly connected to the inner wall of the filter cartridge, and an ion exchange resin layer is fixedly connected to one side of the ultrafiltration membrane, and the inner wall of the filter cartridge is composed of an ultrafiltration membrane and an ion exchange resin layer.

[0010] The present invention is further configured such that a neodymium magnet insert is fixedly connected to one side of the rotating impeller, and magnets are fixedly connected to both sides of the top of the scraper ring, with one side of the magnet being fixedly connected to one side of the scraper.

[0011] The present invention is further configured such that a connecting sleeve is connected to the top of the top cover, and a threaded opening is provided on the surface of the connecting sleeve.

[0012] The present invention is further configured such that a sealing ring is fixedly connected to the top of the partition cylinder, and a sealing groove is provided at the bottom of the extrusion block, with the top of the sealing ring fitting into the inner cavity of the sealing groove.

[0013] The present invention is further configured such that a threaded groove is provided on one side of the surface of the filter cartridge, and the bottom of the top cover is threadedly connected to the top of the filter cartridge through the threaded groove.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model, through the design of a self-cleaning component, utilizes water flow to drive the rotating impeller during the filtration process, and magnetic coupling to drive the scraper ring to rotate synchronously, so that the scraper continuously scrapes away impurities attached to the inner wall of the filter, effectively preventing filter pore blockage. This structure realizes dynamic self-cleaning of the filter element, significantly reduces the accumulation of large impurities, reduces the frequency of manual cleaning by users, and extends the service life of the filter element. At the same time, the composite filter layer includes sintered metal mesh, activated carbon, ultrafiltration membrane and ion exchange resin to form multi-stage filtration, ensuring long-term stable filtration effect.

[0016] 2. This utility model uses a composite structure of pre-compression spring and threaded seal. When the top cover and filter cartridge are tightened, the compression block compresses the pre-compression spring, making the sealing ring fit tightly against the sealing groove, enhancing the sealing performance and preventing water leakage. When disassembling, the spring rebounds and automatically lifts the top cover, preventing the filter element from getting stuck. In addition, the threaded connection structure makes installation and replacement more convenient. Users only need to rotate the top cover to complete the disassembly and assembly, which greatly improves maintenance efficiency and reduces usage costs.

A partition cylinder 3 is fixedly connected to the inner cavity of the filter cartridge 1. When the partition cylinder 3 is in contact with the extrusion block 10, it can seal the inner cavity of the filter cartridge 1 to prevent water from entering the partition cylinder 3 and affecting filtration. A self-cleaning component is provided at the bottom of the top cover 2, including a filter 4 fixedly connected to the bottom of the top cover 2. Both the filter 4 and the filter cartridge 1 are cylindrical and have perforations on their surfaces to facilitate filtration. A rotating impeller 5 is movably connected to the inner cavity of the filter 4. When liquid flows into the filter 4, it can drive... The self-rotating impeller 5 rotates, and the scraping ring 6 is movably connected to the inner cavity of the filter 4, and the scraper 7 is set on both sides of the top of the scraping ring 6. The scraper 7 is made of rubber and has a beveled side to facilitate the scraping of impurities on the inner wall of the filter 4. The self-cleaning component is used to scrape the impurities on the inner wall of the filter 4. The inner cavity of the partition cylinder 3 is provided with a sealing component, which includes a pre-compression spring 8 fixedly connected to the bottom of the partition cylinder 3, a pressure plate 9 fixedly connected to one end of the pre-compression spring 8, the pressure plate 9 sliding inside the partition cylinder 3, and a squeezing block 10 fixedly connected to the bottom of the filter 4. The bottom of the squeezing block 10 fits against the top of the pressure plate 9. The sealing component is used to improve the sealing between the filter cylinder 1 and the top cover 2.

[0028] Example 2

[0029] Please see Figures 1-5Based on Example 1, a sintered metal mesh 11 is fixedly connected to the inner wall of filter 4 to trap large particulate impurities in the water and to provide mechanical support for the inner activated carbon layer. An activated carbon filter layer 12 is fixedly connected to one side of the sintered metal mesh 11 to adsorb residual chlorine, organic matter, and off-colors and odors. The inner wall of filter 4 is composed of a composite of sintered metal mesh 11 and activated carbon filter layer 12. An ultrafiltration membrane 13 is fixedly connected to the inner wall of filter cartridge 1 to trap bacteria, colloids, some viruses, and small particles. An ion exchange resin layer 14 is fixedly connected to one side of ultrafiltration membrane 13 to remove calcium and magnesium ions through sodium ion exchange and reduce water hardness. The inner wall of filter cartridge 1 is composed of a composite of ultrafiltration membrane 13 and ion exchange resin layer 14. A neodymium magnet insert 15 is fixedly connected to one side of the rotating impeller 5 and symmetrically embedded in the rotating impeller. The edge of the impeller 5 has alternating SN poles. The magnet 16 has opposite magnetic poles to the impeller 5 and rotates synchronously with the impeller 5 through magnetic coupling, scraping the inner wall of the filter cartridge 1. Magnets 16 are fixedly connected to both sides of the top of the scraping ring 6. One side of the magnet 16 is fixedly connected to one side of the scraper 7. The top of the top cover 2 is connected to the connecting sleeve 17. The surface of the connecting sleeve 17 has a threaded opening. The threaded opening is used to connect the filter 4 with the external structure for transmitting the liquid to be filtered, which facilitates the filtration work. The top of the partition cylinder 3 is fixedly connected to the sealing ring 18. The bottom of the squeezing block 10 has a sealing groove. The sealing ring 18 and the sealing groove ensure that the partition cylinder 3 can be sealed to the outside. The top of the sealing ring 18 fits into the inner cavity of the sealing groove. A threaded groove is opened on one side of the surface of the filter cartridge 1. The bottom of the top cover 2 is threadedly connected to the top of the filter cartridge 1 through the threaded groove.

[0030] The working principle of this utility model is as follows: When the liquid to be filtered enters the filter element through the connecting sleeve 17 of the top cover 2, it first flows through the sintered metal mesh 11 on the inner wall of the filter 4 to intercept large particles of impurities. Then, the water flows through the activated carbon filter layer 12 to adsorb residual chlorine, organic matter and odor. Next, the water flow drives the self-rotating impeller 5 to rotate. The impeller is magnetically coupled to the magnet 16 of the scraper ring 6 through the neodymium magnet insert 15, which drives the scraper ring 6 to rotate synchronously, so that the scraper 7 continuously scrapes off the impurities attached to the surface of the ultrafiltration membrane 13. Then, the water flows through the ultrafiltration membrane 13 and the ion exchange resin layer 14 on the inner wall of the filter cartridge 1 in sequence, intercepting bacteria, colloids and other small particles, softening the water quality and removing heavy metal ions, completing multi-stage purification. The purified water is discharged from the leaks on the side wall and bottom of the filter cartridge 1.

[0031] During this process, when the top cover 2 and the filter cartridge 1 are tightened by the threaded connection, the squeezing block 10 compresses the pre-compression spring 8 in the partition cylinder 3, so that the sealing ring 18 fits tightly with the sealing groove to ensure sealing. When disassembling, the spring rebounds and automatically lifts the top cover 2 to avoid jamming. The entire system realizes the integrated operation of dynamic self-cleaning and high-efficiency filtration.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
