[0031] As shown in Figures 1-5 A sewage drainage pipeline structure, comprising a pipeline body 1, a spiral flow guide unit 2, a detachable filter module 3 and a modular connection system 4.

[0032] The pipeline body 1 adopts a multi-layer structure, the outer layer is a high-density polyethylene anticorrosive layer 11 with a thickness of 1.5-2.5mm, the middle layer is a reinforcing layer 12 woven at an angle of 45° of basalt fiber, and the inner layer is a nano-silicate coating inner lining 13. This structure can effectively improve the corrosion resistance and mechanical strength of the pipeline, especially the 45° angle woven reinforcing method of basalt fiber, which improves the compressive strength compared with the conventional orthogonal woven method.

[0033] The inner wall of the pipeline body 1 is provided with continuous spiral flow guide convex ribs 21, the flow guide convex ribs 21 are injection molded, the spiral angle is 15°-25°, the distance between adjacent flow guide convex ribs gradually increases along the water flow direction, preferably, the first section distance is 60-80mm, and the last section distance is 100-120mm. This design can optimize the flow state of water flow and reduce the deposition of sewage in the pipeline.

[0034] The pipeline body 1 is provided with an inspection opening 31 at the top, and a filter screen 33 is installed in the inspection opening 31 through a slide rail 32, and a spring self-locking mechanism 34 is arranged outside the filter screen. The filter screen is formed by laser cutting of 316L stainless steel, and the surface is treated by electrolytic polishing, with a roughness Ra≤0.8μm and a pore size ≤5mm. This design can effectively filter large particles in sewage, and is convenient to maintain and replace. The inspection opening is provided with a sealing cover, which can meet the sealing requirements.

[0035] The pipeline body 1 is provided with a quick buckle joint 41 at both ends, a sealing ring 42 is embedded inside, a locking hoop 43 is arranged outside, and a handle 44 is arranged on both sides. This modular connection system can ensure the sealing and reliability of the pipeline connection and reduce leakage.

[0036] Working principle:

[0037] When the sewage enters the pipeline, the water flow forms a spiral flow along the spiral guide convex rib 21. This flow mode can effectively reduce the deposition of sewage in the pipeline and reduce the risk of blockage.

[0038] When the sewage passes through the filter screen 33, large particles are intercepted by the filter screen, and the filtered sewage continues to flow along the pipeline.

[0039] When the filter screen needs to be cleaned or replaced, the filter screen is pulled out along the slide rail 32 through the inspection opening 31, and the spring self-locking mechanism 34 can ensure the stability of the filter screen during the pulling out and installation process.

[0040] When the pipeline is connected, the two sections of the pipeline are connected through the quick buckle joint 41, the sealing ring 42 is embedded inside to ensure the sealing of the connection, the locking hoop 43 is further fixed, and the buckle joint is connected and fixed by rotating the handles 44 on both sides. This modular connection system can ensure the sealing and reliability of the pipeline connection and reduce leakage.

[0041] In summary, the present application has the advantages of simple structure, optimized pipeline internal structure and functional modules, effectively solving the problems of deposition, blockage, insufficient filtration and poor connection reliability in existing drainage pipelines, and has the advantages of optimized water flow, efficient filtration, reliable connection, strong corrosion resistance and convenient maintenance, and is suitable for urban sewage discharge, industrial wastewater treatment and transportation fields.
