Description

Technical Field

[0001] This utility model belongs to the field of industrial hose technology, and particularly relates to embedded fully conductive UPE hose. Background Technology

[0002] Industrial hoses, also known as industrial rubber hoses, are flexible pipes used in industrial equipment to transport media such as liquids, gases, and solid particles. They are characterized by resistance to chemical corrosion, temperature and pressure, and adaptability to complex environments. Ultra-high molecular weight polyethylene (UPE) has become an ideal pipe material for conveying abrasive materials (such as dust and particles) due to its extremely high wear resistance (higher than carbon steel), self-lubrication, and chemical corrosion resistance.

[0003] During transportation, friction between materials and the inner wall of the pipe easily generates a large amount of static electricity. If this static electricity cannot be discharged in time, it may accumulate and cause spark discharge, leading to combustion or explosion accidents, seriously threatening production safety and personnel lives. Many existing conductive hoses use surface coatings or single embedded metal wires, resulting in incomplete conductive pathways and poor durability. During use, wear, bending, or aging can easily cause a decline in conductive performance or even failure. Furthermore, the wear resistance and corrosion resistance of ordinary hose linings are insufficient, making it difficult to simultaneously meet the safety and durability requirements under harsh working conditions. Therefore, we propose an embedded fully conductive UPE hose. Utility Model Content

[0004] The purpose of this invention is to provide an embedded fully conductive UPE flexible tube to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides an embedded fully conductive UPE flexible hose, comprising a composite hose body, the composite hose body including an outer protective layer, an inner wall of the outer protective layer being provided with a conductive reinforcing layer, a spiral conductive metal wire being embedded inside the conductive reinforcing layer, the spiral conductive metal wire being uniformly wound along the length of the hose and embedded in the hose wall, a UPE inner liner being fixedly connected to the inner wall of the conductive reinforcing layer, a conductive filler being uniformly dispersed inside the UPE inner liner, and a smooth conductive coating being applied to the inner surface of the UPE inner liner.

[0006] In the above technical solution, one end of the composite hose body is provided with a connecting joint, the outer surface of the connecting joint is also provided with connecting threads and a grounding terminal, and an identification sticker is affixed to the outer surface of the composite hose body.

[0007] In the above technical solution, the electrostatic conductive reinforcing layer is further described as a polymer composite material layer doped with carbon fiber or metal fiber.

[0008] In the above technical solution, the spiral electrostatic conductive metal wire is further described as copper-plated steel wire or stainless steel wire.

[0009] In the above technical solution, the UPE inner liner is made of ultra-high molecular weight polyethylene substrate, and the electrostatic conductive filler is conductive carbon black or metal powder.

[0010] In the above technical solution, furthermore, the interior of the composite hose body is provided with a reinforcing layer, which is a high-strength polyester fiber braided layer and is located between the outer protective layer and the UPE inner lining layer.

[0011] The beneficial effects of this utility model are: 1. This embedded fully conductive UPE hose features a spiral conductive metal wire embedded in the conductive reinforcement layer. Together with the uniformly dispersed conductive filler in the UPE liner and the smooth conductive coating on the inner surface, it forms a continuous and complete fully conductive path. This allows for the rapid and effective discharge of static electricity generated during transport, preventing static buildup and significantly reducing the risk of spark discharge in the transport of flammable and explosive media, thus improving transport safety. The UPE liner has excellent wear resistance and chemical corrosion resistance. Combined with the outer protective layer and the conductive reinforcement layer, the overall structure is robust, flexible, and durable, suitable for various harsh working conditions, and extends the service life of the hose.

[0012] 2. This embedded fully conductive UPE hose uses an outer protective layer to resist external impacts, aging, and wear, protecting the internal structure. The high-strength polyester fiber braided layer of the reinforcing layer improves the hose's tensile and bending resistance, preventing delamination and breakage. The UPE inner lining layer, made of ultra-high molecular weight polyethylene substrate and combined with conductive filler, balances wear resistance and electrostatic conductivity, extending the service life several times compared to traditional linings. Each layer is composited using a special process, resulting in a tight bond and eliminating the risk of delamination. Attached Figure Description
