[0001] The present invention relates to the technical field of hydropower hydrogen production, and in particular to a device for filtering and removing impurities from water used in hydropower hydrogen production. Background Art

[0002] In the field of hydropower hydrogen production, the purity of water is crucial to the efficiency and safety of the hydrogen production process. However, natural water bodies or water that has undergone preliminary treatment often contain various impurities, such as suspended matter, particulate matter, organic matter, etc. If these impurities enter the hydropower hydrogen production system directly, it will not only reduce the efficiency of water electrolysis, but may also cause corrosion, blockage and other damage to the equipment, affecting the stable operation of the system and the purity of hydrogen. Therefore, effective filtration and impurity removal of water bodies before hydropower hydrogen production is an indispensable step. Although traditional water filtration methods can remove some impurities, they often have problems such as low filtration efficiency, inconvenient impurity cleaning, and unstable filtration effects. Especially in application scenarios that require continuous and efficient hydrogen production, how to quickly and effectively remove impurities accumulated during the filtration process while ensuring the continuous and stable operation of the filtration system has become a technical problem that needs to be solved urgently.

Throughout this application, unless otherwise specified, "plurality" means two or more.

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0038] See Figure 1-7 As shown, the water filtering and impurity removing device for water energy hydrogen production according to the embodiment of the application comprises:

[0039] The filter box 1 is provided with a liquid inlet 2 at the top, a support column 3 at the bottom, and a liquid outlet 4 at the bottom, and a box door 5 on one side.

[0040] The filter assembly is arranged inside the filter box 1.

[0041] The scraper assembly is arranged at the top of the filter box 1, and the mounting end of the scraper assembly is fixedly connected to the top of the filter box 1.

[0042] In some embodiments, the support column 3 is provided with a plurality of support columns 3, and the top of each of the plurality of support columns 3 is fixedly connected to the bottom of the filter box 1.

[0043] In some embodiments, a valve is arranged at the liquid outlet 4.

[0044] In some embodiments, one side of the box door 5 is hinged to the side wall of the filter box 1.

[0045] In some embodiments, the filter assembly comprises:

[0046] The fixing assembly is arranged inside the filter box 1 and is fixedly connected to the inner wall of the filter box 1.

[0047] The filter plate 6 is arranged inside the filter box 1 and is arranged obliquely, and the mounting end of the filter plate 6 is fixedly connected to the fixing assembly by bolts.

[0048] In some embodiments, the fixing assembly comprises a first connecting block 7 and a second connecting block 8, and the same side end of the first connecting block 7 and the second connecting block 8 is fixedly connected to the inner wall of the filter box 1, and the mounting end of the filter plate 6 is arranged between the first connecting block 7 and the second connecting block 8.

[0049] It should be understood that the plurality of support columns 3 are evenly distributed on the bottom of the filter box 1 and are fixedly connected to the bottom of the filter box 1, thereby providing stable support structure for the filter box 1. When the filter box 1 is filled with water, the weight of the water will generate downward pressure on the filter box 1, and the support column 3 can withstand this part of the pressure to prevent the filter box 1 from being deformed or damaged due to its own weight, thereby ensuring the stability of the structure of the filter box 1 during long-term use. The arrangement of the plurality of support columns 3 makes the stress on the bottom of the filter box 1 more uniform, effectively avoiding the deformation problem caused by excessive local stress, greatly improving the overall stability of the filter box 1, and ensuring its normal operation under various working conditions.

[0050] A valve is provided at the liquid outlet 4 of the filter box 1. When the filtration process is completed and the filtered water needs to be discharged, the valve is opened and the water flows out from the liquid outlet 4 under the action of gravity. When drainage is not required, closing the valve can prevent water leakage. It is also convenient for controlling the water level in the filter box 1, maintaining a certain water level difference, and allowing the filtration process to proceed continuously and stably. The presence of the valve allows the operator to accurately control the discharge of water according to actual needs, achieve flexible adjustment of the water level in the filter box 1, meet different filtration tasks and process requirements, and ensure the consistency of the filtration effect. In the non-drainage state, closing the valve can effectively prevent water from accidentally leaking from the liquid outlet 4, avoiding waste of water resources and pollution to the surrounding environment. It also ensures the sealing of the filtration system and maintains the normal working pressure inside the system.

[0051] One side of the door 5 is hinged to the side wall of the filter box 1. This connection allows the door 5 to be opened and closed by rotating around the hinge axis like a door. When cleaning the interior of the filter box 1, replacing the filter assembly, or inspecting the equipment, the door 5 can be opened by gently turning it, allowing the operator to easily access the interior of the filter box 1. During normal use, the door 5 closes tightly, effectively preventing external impurities from entering the filter box 1 and ensuring a clean filtration environment. The hinged door 5 is easy to open and close, requiring no additional tools or complex steps. The operator can easily open the door 5 to perform various maintenance tasks inside the filter box 1, such as cleaning impurities and checking the equipment's operating status. This significantly reduces maintenance time and improves the equipment's operability and maintainability. When closed, the door 5 fits tightly against the side wall of the filter box 1, forming a good seal that effectively prevents external dust and impurities from entering the filter box 1, preventing interference with the filtration process and ensuring the purity of the filtered water. It also helps maintain stable environmental conditions such as temperature and humidity within the filter box 1.

[0052] The ipsilateral ends of the first and second connecting blocks 7, 8 are fixedly connected to the inner wall of the filter box 1. The mounting end of the filter plate 6 is positioned between the two and securely fastened to the connecting blocks by bolts. This securement ensures that the filter plate 6 remains fixed and stable within the filter box 1, preventing displacement or shaking due to the impact of the water flow or other external forces, thus ensuring the proper functioning of the filtration process. Through the clamping action of the first and second connecting blocks 7, 8, and the tightening of the bolts, the filter plate 6 is securely fixed within the filter box 1, capable of withstanding the pressure and impact of the water flow. This prevents the filter plate 6 from loosening or deforming during long-term use, thereby ensuring the stability and reliability of the filtration effect. To install or replace the filter plate 6, simply loosen the bolts, insert or remove the filter plate 6 between the first and second connecting blocks 7, 8, and then retighten the bolts. This simple and quick operation eliminates the need for extensive disassembly and assembly of the filter box 1, reducing maintenance costs and workload and improving the maintainability of the equipment.

[0053] The filter plates 6 are arranged at an angle within the filter box 1. After water enters the filter box 1 through the liquid inlet 2, it flows along the inclined surface of the filter plates 6. Because the filter plates 6 have a specific pore size or filter medium, impurities in the water are trapped on the surface of the filter plates 6, while clean water continues to flow through the filter plates 6 to the liquid outlet 4. As the filtration process progresses, impurities gradually accumulate on the surface of the filter plates 6. When the accumulation reaches a certain level, the scraper assembly removes them. The inclined filter plates 6 facilitate smooth water flow and reduce resistance. They also increase the filtration area, allowing for more contact between the water and the filter plates 6, thereby improving filtration efficiency and enabling the processing of larger volumes of water in a shorter time, meeting the needs of large-scale hydropower hydrogen production. Impurities tend to accumulate on the inclined surface of the filter plates 6 and slide to one side, making impurity removal more convenient. Combined with the scraper assembly, impurities on the surface of the filter plates 6 can be removed promptly and effectively, preventing excessive accumulation that could affect filtration efficiency and extending the service life of the filter plates 6.

[0054] In some specific embodiments, the filter assembly also includes a limit plate 9, two of which are fixedly connected to the inner wall of the box door 5, the axial cross-section of the limit plate 9 is an L-shaped structure, and a limit groove 10 is provided in the limit plate 9.

[0055] In some specific embodiments, the filter assembly also includes a filter funnel 11, and two limiting columns 12 are provided on both sides of the filter funnel 11 corresponding to the two limiting grooves 10. The two limiting columns 12 are fixedly connected to the side walls of the filter funnel 11, and the limiting columns 12 match the limiting grooves 10. The top of the filter funnel 11 is provided with an opening, and the top of the filter funnel 11 is on the same horizontal line as the end of the filter plate 6 away from the first connecting block 7, and the top of the filter funnel 11 is abutted against the end of the filter plate 6 away from the first connecting block 7.

[0056] It should be understood that when the door 5 is closed, the position of the limit plate 9 corresponds to the installation position of the filter funnel 11, providing lateral and longitudinal positioning support for the filter funnel 11. Limiting posts 12 that match the limiting grooves 10 are provided on both sides of the filter funnel 11. The limiting posts 12 and the limiting grooves 10 are plugged into each other to achieve precise positioning. The top opening of the filter funnel 11 is on the same horizontal line as the end of the filter plate 6 away from the first connecting block 7, and the two are in contact with each other. When the impurities (such as sediment and particulate matter) intercepted by the filter plate 6 accumulate to a certain extent, the impurities will slide along the inclined filter plate 6 into the filter funnel 11, achieving centralized collection of impurities. The seamless fit between the top of the filter funnel 11 and the filter plate 6 ensures that impurities will not leak out of the gap, but will all enter the filter funnel 11. When too many impurities accumulate in the filter funnel 11, the filter funnel 11 can be easily removed for cleaning or replacement by simply opening the door 5. The detachable design of the limiting column 12 and the limiting groove 10 makes the disassembly and assembly process of the filter funnel 11 simple and quick without the need for tools, thereby reducing maintenance costs and time.

[0057] In some specific embodiments, the scraper assembly includes:

[0058] The servo motor 13 is provided at the top of the filter box 1 , wherein the mounting end of the servo motor 13 is fixedly connected to the top of the filter box 1 , and the movable end at the bottom of the servo motor 13 extends into the interior of the filter box 1 ;

[0059] A moving rod 14, the top of which is fixedly connected to the moving end of the bottom of the servo motor 13;

[0060] The movable column 15 has an inner cavity 19 provided therein. An opening is provided at the top of the movable column 15. The bottom of the movable rod 14 extends into the inner cavity 19. The inner diameter of the inner cavity 19 is larger than the outer diameter of the movable rod 14. The bottom of the movable column 15 is fixedly connected to an inclined scraper 16. The bottom of the inclined scraper 16 abuts against the top of the filter plate 6.

[0061] The bottom of the spring 17 is fixedly connected to the bottom wall of the inner cavity 19 , and the top of the spring 17 is fixedly connected to the bottom of the moving rod 14 .

[0062] In some specific embodiments, an observation panel 18 is provided on the outer side wall of the filter box 1 .

[0063] It should be understood that the servo motor 13 is installed on the top of the filter box 1, and its moving end (such as a screw or push rod) extends into the interior of the filter box 1, providing power through rotation or linear motion. The top of the moving rod 14 is fixedly connected to the moving end of the servo motor 13, transmitting the power of the servo motor 13 to the moving column 15. An inner cavity 19 is provided inside the moving column 15, and the bottom of the moving rod 14 extends into the inner cavity 19 and is connected to the bottom wall of the inner cavity 19 through a spring 17. The bottom of the inclined scraper 16 abuts against the top of the filter plate 6, and during the movement, it scrapes off the impurities accumulated on the filter plate 6 and pushes them toward the direction of the filter funnel 11. The setting of the spring 17 provides a buffering and reset function for the moving column 15. When the inclined scraper 16 encounters greater resistance, the spring 17 can be compressed to avoid damage to the equipment; when the resistance disappears, the spring 17 pushes the moving column 15 and the inclined scraper 16 to reset, ensuring the normal operation of the scraper assembly. Because filter plate 6 is tilted, spring 17 is in a compressed state when being in one end away from filter funnel 11. Spring 17 is in the process of moving to filter funnel 11, and spring 17 is gradually stretched. When being in the other end of filter plate 6, spring 17 is in a normal state.

[0064] The servo motor 13 has high control accuracy and can adjust the speed and force of the scraper according to the degree of contamination of the filter plate 6 to adapt to different working conditions. The coordinated design of the moving column 15 and the moving rod 14, as well as the reset function of the spring 17, ensure the stability and reliability of the scraper assembly in long-term use.

[0065] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
