[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Referring to Figures 1 to 4 As shown, the present invention provides a high-flow reverse osmosis membrane filter element, including: a filter element main body 1 and a sealing plate 13. Water inlets 3 are symmetrically formed on the outer side surface of the filter element main body 1, a bottom sealing groove 2 is formed at the bottom of the inner cavity of the filter element main body 1, a side sealing groove 8 is formed on the side surface of the inner cavity of the filter element main body 1, and a fixing plate 5 is slidably connected to the inside of the filter element main body 1 through the side sealing groove 8 and the bottom sealing groove 2. A reverse osmosis membrane main body 4 is fixedly connected inside the fixing plate 5. At the same time, the upper surface of the filter element main body 1 is fixedly connected to a cover plate 9 by bolts. Auxiliary through holes and main through holes are respectively formed on the surface of the cover plate 9 at positions corresponding to the waste water pipe 10 and the central pipe 12.

At the same time, a top sealing groove 14 is correspondingly formed on the lower surface of the sealing plate 13 at the position corresponding to the fixing plate 5.

[0019] In this embodiment, after the reverse osmosis membrane filter element is installed in a suitable position, the water to be treated will flow into the interior of the filter element main body 1 through the water inlet 3. Subsequently, the water to be treated will be filtered accordingly through the reverse osmosis membrane main body 4, enabling the purified water to flow from the edge of the filter element main body 1 to the middle, and the purified water can flow out through the central tube 12. The concentrated water on the side of the reverse osmosis membrane main body 4 close to the water inlet 3 can be discharged through the wastewater pipe 10. At the same time, the structural setting of the reverse osmosis membrane main body 4 can increase the filtration area of the water to be treated, thereby increasing the flow rate of this reverse osmosis membrane filter element. When this reverse osmosis membrane filter element needs to be cleaned, first take out the filter element main body 1, remove the bolts and the cover plate 9, so that the sealing plate 13 is exposed to the external environment, then take out the sealing plate 13, release the restriction of the filter element main body 1 on the fixing plate 5, and then the fixing plate 5 inside the filter element main body 1 and its corresponding reverse osmosis membrane main body 4 can be taken out one by one, reducing the disassembly difficulty of the reverse osmosis membrane filter element, while improving the convenience and flexibility during the cleaning of the reverse osmosis membrane main body 4, reducing the probability of damage to the relevant structures inside the reverse osmosis membrane filter element. At the same time, when a damaged reverse osmosis membrane main body 4 needs to be replaced, it can be independently replaced, reducing the cost of component replacement.

At the same time, a sealing ring 6 is fixedly connected to the upper end of the outer side of the filter element main body 1, and the sealing ring 6 is in a circular ring structure.

At the same time, the setting of the sealing ring 6 can assist in enhancing the sealing performance after the installation of this reverse osmosis membrane filter element.

[0022] As a preferred embodiment, eight groups of side sealing grooves 8 are circumferentially and equidistantly arranged on the inner side of the filter element main body 1, and the eight groups of side sealing grooves 8 are all in a long strip structure, and the upper ends of the side sealing grooves 8 communicate with the upper surface of the filter element main body 1.

[0024] As a preferred embodiment, four groups of bottom sealing grooves 2 are circumferentially and equidistantly arranged at the bottom of the inner cavity of the filter element body 1. The four groups of bottom sealing grooves 2 are all in a U-shaped structure, and both ends of each group of bottom sealing grooves 2 are respectively communicated with two corresponding groups of side sealing grooves 8.

[0025] In this embodiment, as shown in Figure 1 and Figure 2 , a gasket is fixedly connected inside the bottom sealing groove 2. Then, when the lower end of the fixing plate 5 is embedded, the sealing performance of the connection between the lower end of the fixing plate 5 and the bottom sealing groove 2 can be enhanced, and the stability of the connection between the filter element body 1 and the fixing plate 5 can be assisted and enhanced.

[0026] As a preferred embodiment, the fixing plate 5 is integrally in a C-shaped structure. The fixing plate 5 is composed of an inner plate and an outer plate.

And a through groove is respectively opened on three side surfaces of the fixing plate 5. The through groove is communicated with the corresponding installation groove. At the same time, the size of the through groove is smaller than the size of the installation groove.

Then, the sealing performance of the connection between the sealing plate 13 and the filter element body 1 can be assisted and enhanced. And the size of the top sealing groove 14 is adapted to the upper surface size of the fixing plate 5, so as to enhance the sealing performance of the contact surface between the fixing plate 5 and the sealing plate 13. At the same time, the side sealing part 7 is made of silica gel material, which can further enhance the sealing effect of the sealing plate 13 on the side sealing groove 8, ensure that the water to be treated and the concentrated water stay on one side of the water inlet 3 opened by the filter element body 1, and avoid the purified water from being polluted.
