Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to an RO membrane composite filter structure. Background Technology

[0002] RO membrane composite filter technology is a highly efficient water treatment technology that combines the advantages of RO membranes and filter cartridges. It can effectively remove impurities, odors, residual chlorine, and other substances from water, improving water purity. Currently, the internal structure of RO membrane composite filters used in water treatment typically employs a separator, reverse osmosis membrane, and isolation screen. However, water pollution often contains numerous internal impurities, harmful substances, bacteria, and viruses. Simply removing these impurities is insufficient to achieve complete water treatment. Consequently, different types of RO membrane composite filters are needed for individual treatment. This increases the number of RO membrane composite filters required, requiring more installation space and impacting economic costs. Furthermore, the internal structure of RO membrane composite filters is usually non-removable. After long-term use, when a filter cannot be repaired, it must be replaced with a new one to restore filtration capacity, further increasing costs and affecting the filter's performance and durability.

[0003] Therefore, it is necessary to develop an RO membrane composite filter structure. Utility Model Content

[0004] The purpose of this invention is to provide an RO membrane composite filter structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an RO membrane composite filter element structure, comprising an RO membrane filter element shell, wherein an L-shaped slot is provided on one side of the outer wall of the RO membrane filter element shell, and a central tube is installed at the center of the interior of the RO membrane filter element shell;

[0006] A sealing cap is installed at one end of the RO membrane filter cartridge housing.

[0007] Preferably, a reverse osmosis membrane is provided on one side of the outer wall of the central tube, and a water-guiding cloth is provided on the outer wall of the reverse osmosis membrane.

[0008] Preferably, a concentrated water barrier is provided on the outer wall of the water-guiding cloth, and seepage holes are provided on the outer wall surface of the central tube.

[0009] Preferably, a water-sealing ring is provided at both the front and rear ends of the inner side of the central tube.

[0010] Preferably, one end of the inner wall of the sealing cap is slidably connected to one side of the outer wall of the RO membrane filter cartridge housing, and a locking block is provided on one side of the inner wall of the sealing cap.

[0011] Preferably, the outer wall of the card block is slidably connected to the inner wall of the L-shaped card slot, and an inner cylinder is installed at the center of the sealing cover.

[0012] Preferably, a filter screen is installed on one side of the inner cylinder, and activated carbon filter material is installed at one end of the filter screen.

[0013] Preferably, one end of the activated carbon filter media is fitted with quartz sand filter media, and the other end of the quartz sand filter media is fitted with maifan stone filter media.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting the RO membrane composite filter element structure, which consists of a reverse osmosis membrane, a water-conducting cloth, and a concentrate separator, on one side of the outer wall of the central tube, and with the help of several seepage holes on the central tube, the concentrate is filtered and then enters the central tube through the seepage holes before being discharged.

[0016] By installing a filter screen inside the inner cylinder of the sealing cap, and sequentially lining one end of the filter screen with activated carbon filter media, quartz sand filter media, and maifan stone filter media, the concentrated water after initial filtration is prevented from flowing into the filter screen by a water-sealing ring. The activated carbon filter media, quartz sand filter media, and maifan stone filter media then further filter the concentrated water, minimizing the possibility of toxic substances, bacteria, and viruses being difficult to filter. Furthermore, the sealing cap and the RO membrane filter cartridge housing are detachable, allowing for cleaning of the internal filtration structure of the RO membrane filter cartridge housing and the filter media inside the sealing cap. This avoids the need for direct replacement of the RO membrane composite filter cartridge after long-term use, thus increasing costs. This effectively improves the performance and filtration efficiency of the RO membrane composite filter cartridge and ensures its durability. Attached Figure Description

Four sets of locking blocks 301 are correspondingly set on one side of the inner wall of the sealing cap 3. Align the sealing cap 3 with the L-shaped slot 101 on the RO membrane filter housing 1, and rotate it after installation to fix the sealing cap 3 in place. At the same time, the sealing cap 3 and the middle The contact portion of the heart tube 2 can be sealed with a sealing ring to minimize the impact of the removable sealing cap 3 on the sealing performance.

The maifan stone can also dissolve essential amino acids in the aqueous solution. Based on the concentrated water after preliminary filtration, the water sealing ring 205 blocks the flow of the filtered water until it flows into the filter screen 303. Then, it is further filtered by the activated carbon filter media 304, quartz sand filter media 305 and maifan stone filter media 306 to minimize the occurrence of toxic substances and bacteria and viruses in the concentrated water that are difficult to filter.

[0025] Working principle: When using this utility model, the basic RO membrane composite filter element structure, consisting of reverse osmosis membrane 201, water-guiding cloth 202, and concentrate separator 203, is set on one side of the outer wall of the central tube 2. Combined with several seepage holes 204 on the central tube 2, the concentrated water, after filtration, enters the central tube 2 through the seepage holes 204 and is then discharged. Four sets of locking blocks 301 are correspondingly set on one side of the inner wall of the sealing cover 3. Aligning the L-shaped locking slots 101 on the RO membrane filter element housing 1 with these blocks, and then rotating them after installation, the sealing cover 3 is securely installed. Simultaneously, the contact portion between the sealing cap 3 and the central tube 2 can be sealed with a sealing ring to minimize the impact of the removable sealing cap 3 on the sealing performance. A filter screen 303 is installed inside the inner cylinder 302 of the sealing cap 3, and one end of the filter screen 303 is sequentially lined with activated carbon filter media 304, quartz sand filter media 305, and maifan stone filter media 306. The activated carbon filter media 304 utilizes its decolorizing and filtering effects to decolorize colored liquids and absorb various gases and vapors. The quartz sand filter media 305 is free of impurities, has no sharp edges, high density, and mechanical properties. With its high strength, high interception capacity, and long service life, it is an ideal material for chemical water treatment. Utilizing the strong adsorption capacity, mineral dissolution, and water quality adjustment properties of Maifan stone filter media 306, the Maifan stone on the media can adsorb free ions in the water. After passing through water, Maifan stone can dissolve essential macro-elements beneficial to humans and organisms. Maifan stone can also dissolve essential amino acids in aqueous solution. Based on the concentrated water after preliminary filtration, the water flow is blocked by the sealing ring 205 until it flows onto the filter screen 303, where it is further filtered by activated carbon filter media 304 and quartz sand filter media. The 305 and maifan stone filter media 306 further filter the water to minimize the presence of toxic substances, bacteria, and viruses in the concentrate. The sealing cap 3 and the RO membrane filter housing 1 are detachable, allowing for cleaning of the internal filtration structure and filter media within the sealing cap 3 after disassembly. This avoids the need for direct replacement of the RO membrane composite filter after prolonged use, thus increasing costs. This effectively improves the performance and filtration efficiency of the RO membrane composite filter and ensures its durability.
