[0002] As a key water treatment technology, seawater filters originated from advancements in membrane separation, reverse osmosis, and pretreatment processes. Their development has evolved from simple early filters to highly efficient reverse osmosis systems. In particular, breakthroughs in materials science and energy consumption control in the late 20th century led to reduced costs and significantly improved efficiency. Today, they are widely used in areas such as ship desalination, island water supply, coastal industrial cooling, and seawater desalination plants, providing a stable source of freshwater for water-scarce regions.

[0003] Existing seawater reverse osmosis filters generally suffer from inadequate backwashing functionality. Specifically, the backwashing process is independent of the main filtration system, making it impossible to effectively clean the filter cartridge without shutting down the system. This leads to the continuous accumulation of particulate impurities, causing filter cartridge blockage. This not only affects filtration efficiency and water quality stability but also significantly shortens the lifespan of the filter element, increasing system maintenance costs and downtime.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0018] Reference Figures 1-4 This is an embodiment of the present invention, which provides a seawater reverse osmosis filter, comprising: The support mechanism 100 includes a base frame 101, a limiting frame 102 fixedly connected to the side wall of the base frame 101, a water tank 103 fixedly connected to the inner wall of the limiting frame 102, a pump 104 connected to the side wall of the water tank 103, and a mounting frame 105 fixedly connected to the side wall of the base frame 101. The filtration mechanism 200 includes a circulation pump 201 fixedly connected to the side wall of the base frame 101, a Y-type threaded filter 202 connected to the surface of the circulation pump 201, an outlet pipe 203 connected to the side wall of the Y-type threaded filter 202, a flow meter 204 connected to the side wall of the outlet pipe 203, a water pressure gauge 205 connected to the surface of the outlet pipe 203, a transfer pipe 206 connected to the end of the outlet pipe 203, a diversion assembly 207 connected to the side wall of the outlet pipe 203, a circulation assembly 208 connected to the surface of the diversion assembly 207, and a backwash assembly 209 connected to the surface of the diversion assembly 207. The diversion assembly 207 includes a first control valve 207a connected to the side wall of the circulation pump 201, a connecting pipe 207b connected to the side wall of the first control valve 207a, a second control valve 207c connected to the end of the connecting pipe 207b, a filter cartridge 207d connected to the side wall of the second control valve 207c, a tee pipe 207e connected to the surface of the connecting pipe 207b, and a connecting pipe 207f connected to the end of the tee pipe 207e.

[0019] Specifically, the first control valve 207a and the second control valve 207c control the water flow inside the three-way pipe 207e and the connecting pipe 207f, respectively, to ensure that the water flow can pass through different pipes according to the filtration requirements, thus ensuring the filtration effect and ensuring that the device can filter seawater without stopping.

[0020] Furthermore, the circulation assembly 208 includes a first branch pipe 208a connected to the surface of the connecting pipe 207f, and a first branch valve 208b connected to the end of the first branch pipe 208a. The circulation assembly 208 also includes a second branch pipe 208c connected to the surface of the first branch valve 208b, and a water injection pipe 208d connected to the end of the second branch pipe 208c. The circulation assembly 208 also includes a second branch valve 208e connected to the surface of the first branch pipe 208a, and a third branch pipe 208f connected to the side wall of the second branch valve 208e. In this configuration, the second branch valve 208e is closed, the first branch valve 208b is open, and the first branch pipe 208a and the second branch pipe 208c are connected, allowing water to flow through. Conversely, the first branch valve 208b is closed, the second branch valve 208e is open, and the first branch pipe 208a and the third branch pipe 208f are connected, allowing water to flow through and ensuring that the seawater in the device can be circulated and filtered.

[0021] Preferably, the backwash assembly 209 includes a backwash pipe 209a connected to the surface of the filter cartridge 207d, and a fourth branch pipe 209b connected to the surface of the connecting pipe 207f. The backwash assembly 209 also includes a guide pipe 209c connected to the surface of the fourth branch pipe 209b, and a first reverse osmosis filter element 209d connected to the surface of the guide pipe 209c. The backwash assembly 209 also includes a second reverse osmosis filter element 209e fixedly connected to the side wall of the mounting bracket 105, and a third reverse osmosis filter element 209f fixedly connected to the side wall of the mounting bracket 105.

[0022] It should be noted that the backwash assembly 209 is connected to the filter cartridge 207d via the backwash pipe 209a, and is used to periodically backwash the filter cartridge 207d to remove trapped impurities. The fourth branch pipe 209b draws out a portion of the water flow from the connecting pipe 207f and flows through the guide pipe 209c to the first reverse osmosis filter cartridge 209d for preliminary desalination. The second and third reverse osmosis filter cartridges 209f are installed in parallel on the side wall of the mounting frame 105, together forming a multi-stage reverse osmosis filtration core to improve seawater desalination efficiency and water purity.

[0023] In operation, seawater is drawn from water tank 103 by extraction pump 104, pressurized by circulation pump 201, and first enters Y-type threaded filter 202 for preliminary coarse filtration. The water then flows through outlet pipe 203 and its parameters are monitored by flow meter 204 and pressure gauge 205. In the diversion assembly 207, by adjusting the opening and closing states of first control valve 207a and second control valve 207c, the water flow can be guided to filter cartridge 207d for fine filtration or enter the next stage through three-way pipe 207e and connecting pipe 207f. When circulation filtration is required... The circulation component 208 controls the opening and closing of the first branch valve 208b and the second branch valve 208e, allowing water to either flow back through the water injection pipe 208d or enter the internal circulation pipeline. At the same time, the backwash component 209 is activated periodically, using the backwash pipe 209a to backwash the filter cartridge 207d to remove accumulated impurities. Meanwhile, a portion of the water flows through the fourth branch pipe 209b and the guide pipe 209c, sequentially passing through the first, second, and third reverse osmosis filter cartridges 209f, completing multi-stage reverse osmosis desalination treatment and ultimately achieving a continuous and efficient seawater desalination process.

[0024] In summary, the support mechanism 100 and the filtration mechanism 200 are designed to facilitate cooperation among the components. The support mechanism 100 provides a stable basic framework for the entire system, ensuring the reliable fixation of the water tank 103, pump body, and filtration unit. The filtration mechanism 200 drives the fluid through the circulation pump 201. After the Y-type filter initially intercepts impurities, the flow path is intelligently controlled by the diversion component 207. The fluid can be directed to the filter cartridge 207d for deep filtration or diverted to the reverse osmosis unit via the three-way pipe 207e. The circulation component 208 achieves dual-mode operation of water injection return and internal circulation through the flexible switching of the branch valve, effectively extending the life of the filter media. The backwash component 209 works with the filter cartridge 207d and the reverse osmosis module to periodically start reverse flushing to remove accumulated impurities. At the same time, the water quality is purified step by step through the series arrangement of multi-stage reverse osmosis filter cartridges. This not only ensures continuous and uninterrupted seawater treatment capacity but also improves the system's adaptability and energy efficiency. Ultimately, a highly efficient, stable, and low-maintenance seawater desalination solution is achieved within a limited space.
