[0002] In recent years, the plastic pipe industry in China has developed vigorously, and the product quality has been significantly improved. A diversified plastic pipe industry pattern with polyvinyl chloride (PVC-U) pipes, polyethylene (PE) pipes, and polypropylene (PP-R) pipes as the core has been established. Among them, polyethylene (PE) pipes have shown excellent performance in many fields due to their outstanding corrosion resistance, good flexibility, and excellent anti-aging performance, especially playing an important role in key infrastructure such as urban water supply systems, gas transmission networks, and agricultural irrigation systems.

[0003] However, in practical application scenarios such as agricultural irrigation, PE pipes face the problem of pipeline blockage. Since the irrigation water source often contains impurities such as soil and sand, these impurities gradually accumulate in the pipeline, which not only affects the smooth flow of water but also may cause serious blockage phenomena, significantly reducing the service efficiency and lifespan of PE pipes.

[0004] To solve this problem, PE pipe products equipped with filtering devices have emerged on the market, aiming to intercept and remove impurities through physical filtration. However, although the existing filtering devices can reduce the entry of impurities into the pipeline to a certain extent, their ability to handle the filtered impurities is insufficient. Specifically, the filtering devices lack an effective impurity cleaning mechanism, resulting in the accumulation of filtered impurities inside the device. Over time, these accumulated impurities may also become new blockage sources, thus failing to fundamentally solve the problem of pipeline blockage. Summary of the Invention

[0021] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Please refer to Figures 1 to 6 , to achieve the above object, the present utility model provides the following technical solutions:

[0023] An anti-blocking PE pipe structure includes a first PE pipe 1 and a second PE pipe 2, and an anti-blocking filter assembly 3 is provided between the first PE pipe 1 and the second PE pipe 2; the anti-blocking filter assembly 3 includes a filter cartridge 301, wherein a water inlet pipe 302 and a water outlet pipe 303 are respectively arranged on both sides of the filter cartridge 301, and both the water inlet pipe 302 and the water outlet pipe 303 are communicated with the inner cavity of the filter cartridge 301; the water inlet end of the water inlet pipe 302 is connected to the first PE pipe 1, and the water outlet end of the water outlet pipe 303 is connected to the second PE pipe 2; a filter plate 304 is arranged in the inner cavity of the filter cartridge 301, and a removable filter screen 305 is arranged on the filter plate 304; a sealing cover 306 is arranged at the upper end of the filter cartridge 301, and the lower end of the sealing cover 306 is fixedly connected to the filter plate 304 through a connecting rod 307; a drainage port 308 is opened at the lower end of the filter cartridge 301, and a control valve 4 is installed at the drainage port 308.

[0024] When irrigation water or other fluids flow from the first PE pipe 1, the water flow first enters the inner cavity of the filter cartridge 301 of the anti-clogging filter assembly 3 through the water inlet end of the water inlet pipe 302. The setting of the water inlet pipe 302 ensures that the water flow can smoothly enter the filtration system; the water flow entering the inner cavity of the filter cartridge 301 then encounters the detachable filter screen 305 on the filter plate 304. The function of the detachable filter screen 305 is to intercept and remove impurities in the water flow, such as particulate matters like soil and sand, to prevent them from entering the downstream pipeline system; at the same time, the inclined setting of the filter plate 304 helps to guide the impurities in the water flow to deposit below the filter plate 304, further improving the filtration effect; the clean water flow filtered by the detachable filter screen 305 continues to flow to the other side of the filter cartridge 301 and enters the second PE pipe 2 through the water outlet end of the water outlet pipe 303, and finally flows to the predetermined irrigation area or other destinations; over time, the impurities on the filter cartridge 301 will gradually accumulate. To maintain the filtration efficiency, these impurities need to be cleaned regularly; at this time, the control valve 4 at the sewage outlet 308 at the lower end of the filter cartridge 301 can be opened to let the impurities accumulated below the filter plate 304 flow out with the water flow; if more thorough cleaning is needed, the sealing cover 306 can also be removed, and the filter plate 304 and the detachable filter screen 305 thereon can be taken out together through the connecting rod 307 for cleaning or replacement. This detachable design greatly facilitates the maintenance operation; this anti-clogging PE pipe structure effectively intercepts and removes impurities in the water flow through its built-in anti-clogging filter assembly 3, and at the same time ensures the long-term efficient operation of the filter assembly through a convenient impurity cleaning mechanism. This design not only solves the problem of easy clogging of traditional PE pipes but also improves the overall performance and reliability of the pipeline system.

[0025] Please refer to Figure 4 、 Figure 5 As an embodiment of the present utility model, the filter plate 304 has an oval structure. The filter plate 304 is inclined and arranged in the filter cartridge 301, and separates the water inlet pipe 302 and the water outlet pipe 303; the filter plate 304 is inclined at an angle of 30 to 50° with the horizontal plane. One side of the filter plate 304 is arranged above the water outlet end of the water inlet pipe 302, and the other side of the filter plate 304 is arranged below the water inlet end of the water outlet pipe 303.

[0026] In the above-described solution, after the water flow enters the filter cartridge 301 from the water inlet pipe 302, it first encounters the elliptical filter plate 304 arranged obliquely. The inclination angle of the filter plate 304 is 30 to 50°, and this design is neither too gentle nor too steep, which helps the water flow to be evenly distributed on the filter plate 304 and flow along the surface of the filter plate 304; since one side of the filter plate 304 is above the water outlet end of the water inlet pipe 302 and the other side is below the water inlet end of the water outlet pipe 303, this layout enables the water flow to naturally flow along the inclined direction when flowing through the filter plate 304, increasing the contact time and area between the water flow and the filter screen; as the water flow moves, the impurities in it, under the action of gravity and the blocking of the filter screen, begin to deposit below the filter cartridge. Due to the inclination of the filter plate 304, these impurities are more likely to accumulate below the filter plate 304, thereby reducing the influence of the impurities on the effective filtration area of the filter screen; at the same time, the holes or gaps on the filter screen allow the clean water flow to pass through while intercepting the impurities, and this physical filtration mechanism ensures that only the clean water flow can continue to flow towards the water outlet pipe 303; over time, the impurities below the filter cartridge 301 will gradually accumulate. In order to maintain the filtration efficiency, it is necessary to regularly open the control valve 4 at the sewage outlet 308 to let the accumulated impurities flow out with the water flow; because the filter plate 304 is inclined and the impurities are mainly concentrated on the lower side below the filter plate 304, the sewage discharge process is relatively smooth and efficient.

[0027] Please refer to Figure 5 , as an embodiment of the present utility model, a sealing ring 5 is circumferentially arranged along the outer side of the filter plate 304, and the sealing ring 5 abuts against the inner wall of the filter cartridge 301.

[0028] In the above-described solution, the sealing ring 5 is usually made of an elastic material, such as rubber or silica gel, etc. These materials have good elasticity and sealing performance; the main function of the sealing ring 5 is to provide a seal between the filter plate 304 and the inner cavity of the filter cartridge 301. Since the water flow needs to maintain a certain pressure during the filtration process to ensure the filtration effect, the sealing performance is crucial; the presence of the sealing ring 5 can effectively prevent the water flow from leaking in the gap between the filter plate 304 and the filter cartridge 301, ensuring the overall sealing performance of the filtration system; during the filtration process, if there is a gap between the filter plate 304 and the filter cartridge 301, then some unfiltered impurities may directly flow into the water outlet pipe 303 through these gaps, resulting in a decline in the filtration effect; while the presence of the sealing ring 5 can effectively prevent this situation from occurring, ensuring that all water flows must pass through the filtration of the filter screen before flowing out. Since the filter plate 304 needs to withstand the impact of the water flow and the friction of the impurities during operation, its surface and edges are prone to wear; the sealing ring 5, as a buffer layer between the filter plate 304 and the filter cartridge 301, can reduce the direct contact and friction between the filter plate 304 and the filter cartridge 301 to a certain extent, thereby extending the service life of the filter plate 304 and the entire filtration system.

[0029] Please refer to Figure 5 , as an embodiment of the present utility model, a support ring 6 is arranged along the circumferential direction of the inner wall of the filter cartridge 301, wherein the support ring 6 is adapted to the periphery of the filter plate 304 and is used to support the filter plate 304.

[0030] In the above-mentioned solution, the main function of the support ring 6 is to provide a stable support for the filter plate 304. Since the filter plate 304 needs to bear the impact of water flow, the weight of impurities and its own gravity during the filtration process, a solid support structure is required to ensure its stability and safety; the support ring 6 provides all-round support for the filter plate 304 through its perfect adaptation of shape and size to the periphery of the filter plate 304, preventing it from deforming or shifting during operation; in addition to providing support, the support ring 6 also helps to position and fix the filter plate 304. When installing the filter plate 304 in the filter cartridge 301, the support ring 6 serves as a reference surface, enabling the filter plate 304 to be accurately placed in the predetermined position; this helps to ensure the correct relative positions of the filter plate 304 and components such as the water inlet pipe 302, the water outlet pipe 303, and the sewage outlet 308, thus ensuring the smooth operation of the entire filtration system; when water flows through the filter plate 304, a certain pressure will be generated; through its structural design, the support ring 6 can disperse these pressures over a larger area of the inner cavity of the filter cartridge 301, thereby reducing the pressure concentration on the filter plate 304 itself. This helps to extend the service life of the filter plate 304 and reduce the risk of damage caused by uneven pressure; the tight fit between the support ring 6 and the periphery of the filter plate 304 also helps to maintain the sealing performance. Although the sealing ring 5 is the main sealing element, the presence of the support ring 6 can ensure that the gap between the filter plate 304 and the inner cavity of the filter cartridge 301 is as small as possible, thereby enhancing the sealing effect. This helps to prevent water flow and impurities from leaking or accumulating in the gap between the filter plate 304 and the filter cartridge 301; the support ring 6 arranged along the circumferential direction of the inner cavity of the filter cartridge 301 plays important roles such as support, positioning, pressure dispersion, sealing maintenance, and simplifying installation and maintenance in the anti-blocking PE pipe structure, thus ensuring the smooth operation of the entire filtration system and efficient filtration effect.

[0031] Please refer to in combination with Figure 3 , Figure 5 , Figure 6 , as an embodiment of the present utility model, a first sealing ring 7 is provided at the outer edge of the upper opening of the filter cartridge 301, and a second sealing ring 8 is provided along the circumferential direction of the periphery of the sealing cover 306; the outer diameters of the first sealing ring 7 and the second sealing ring 8 are the same, and a clamp 9 is provided on the outer sides of the first sealing ring 7 and the second sealing ring 8; a sealing groove 10 is opened on the inner side of the clamp 9, and the sealing groove 10 is adapted to the first sealing ring 7 and the second sealing ring 8.

[0032] In the above-described solution, the main functions of the first sealing ring 7 and the second sealing ring 8 are to provide a seal between the filter cartridge 301 and the sealing cover 306; since the filtration system needs to maintain a certain pressure difference to ensure the filtration effect, the sealing performance is crucial. Through the close cooperation of the first sealing ring 7 and the second sealing ring 8, it can effectively prevent water flow and impurities from leaking through the gap between the filter cartridge 301 and the sealing cover 306, ensuring the overall sealing performance of the filtration system; in addition to providing a sealing function, the first sealing ring 7 and the second sealing ring 8 also serve as a connection structure between the filter cartridge 301 and the sealing cover 306. Through the same design of their outer diameters, the clamp 9 can be easily sleeved on the outer sides of both, and through the fastening action of the clamp 9, the filter cartridge 301 and the sealing cover 306 are firmly connected together. This connection method is both simple and reliable, ensuring the stability of the filtration system during operation; the sealing groove 10 opened on the inner side of the clamp 9 is adapted to the first sealing ring 7 and the second sealing ring 8, which means that when the clamp 9 is tightened, it will press the two sealing rings tightly together; the design of the sealing groove 10 ensures that the clamp 9 can apply pressure evenly during the tightening process, thus avoiding the problem of poor sealing caused by excessive or too little local pressure; at the same time, the sealing groove 10 also plays a certain guiding role, enabling the clamp 9 to be accurately sleeved on the sealing ring and tightened smoothly; the fastening action of the clamp 9 not only ensures the connection stability between the filter cartridge 301 and the sealing cover 306, but also prevents loosening and leakage problems caused by vibration or water flow impact; through the fastening force of the clamp 9, the two sealing rings are firmly pressed together to form a reliable sealing barrier, which can maintain the stability of the sealing performance even when encountering large impacts or vibrations during operation; this design also simplifies the installation and maintenance process of the filter cartridge 301 and the sealing cover 306. During installation, only need to place the sealing cover 306 at the upper opening of the filter cartridge 301, and sleeve the clamp 9 on the sealing ring and tighten it; when it is necessary to clean or replace the filter plate 304, the clamp 9 can also be easily loosened and the sealing cover 306 and the filter plate 304 can be removed for maintenance. This design improves work efficiency and reduces maintenance costs; it ensures the overall sealing performance and stability of the filtration system, thus guaranteeing the high efficiency and reliability of the filtration effect.

The protection scope of the present utility model is defined by the appended claims. Without departing from the principles and essence of the present utility model, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the present utility model.
