Description

Technical Field

[0001] This utility model relates to the field of air conditioner accessories technology, and in particular to a wear-resistant superhydrophobic self-cleaning PVC-U condensate pipe for air conditioners. Background Technology

[0002] In air conditioning systems, condensate drain pipes are used to drain the condensate produced during air conditioning operation. Currently, the commonly used PVC-U condensate drain pipes have some issues during use.

[0003] On the one hand, because condensate may contain impurities, the inner wall of the water pipe is easily worn down under the long-term flushing of the water flow, which shortens the service life of the water pipe. On the other hand, scale, algae and other substances are easily attached to the inner wall of the water pipe, which not only affects the discharge efficiency of condensate, but also easily breeds bacteria and produces odors. The existing PVC-U condensate pipes have poor self-cleaning performance and require regular manual cleaning, which increases maintenance costs and workload.

[0004] Therefore, there is an urgent need to design a wear-resistant PVC-U condensate drain pipe for air conditioners with superhydrophobic self-cleaning function to solve the above problems. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] To address the issue that existing PVC-U condensate pipes have poor self-cleaning performance and require regular manual cleaning, which increases maintenance costs and workload.

[0007] (2) Technical solution

[0008] The technical solution of this utility model is as follows: a wear-resistant, superhydrophobic, self-cleaning PVC-U condensate pipe for air conditioning, comprising a PVC-U pipe body, wherein the inner wall of the PVC-U pipe body is provided with a wear-resistant layer and a superhydrophobic layer in sequence; the wear-resistant layer is formed by coating the inner wall of the PVC-U pipe body with a mixture of silicon carbide particles and epoxy resin, and the superhydrophobic layer is formed by coating the surface of the wear-resistant layer with a mixture of nano-silica particles and fluoropolymer; the outer wall of the PVC-U pipe body is provided with a heat insulation layer, and the outer surface of the heat insulation layer is provided with spiral reinforcing ribs; both ends of the PVC-U pipe body are respectively provided with connectors, and the inner side of the connectors is provided with sealing rings.

[0009] Furthermore, the wear-resistant layer has a thickness of 0.3-0.5 mm and the silicon carbide particles have a particle size of 1-5 μm. By uniformly dispersing the fine silicon carbide particles in the epoxy resin, the wear-resistant layer has good wear resistance and impact resistance, and can effectively resist the erosion and wear of impurities in the condensate.

[0010] Furthermore, the thickness of the superhydrophobic layer is 0.1-0.3 mm, the particle size of the nano-silica particles is 20-100 nm, the fluoropolymer can reduce the surface energy, and the nano-silica particles form a rough structure. The combination of the two gives the superhydrophobic layer excellent superhydrophobic properties. The contact angle of water droplets on the surface of the superhydrophobic layer is greater than 150° and the roll-off angle is less than 10°, which allows condensate to roll off quickly, carrying away impurities attached to the inner wall of the water pipe, realizing a self-cleaning function, keeping the inside of the water pipe clean, and ensuring the smooth flow of water.

[0011] Furthermore, the insulation layer is a polyurethane foam insulation layer with a thickness of 5-10mm. Polyurethane foam has good thermal insulation performance and can effectively prevent condensation on the surface of the condensate pipe, avoiding problems such as dampness and mold on the wall caused by condensation.

[0012] Furthermore, the reinforcing rib is made of the same material as the PVC-U pipe body, with a height of 3-5mm and a width of 2-4mm. The spiral reinforcing rib can enhance the compressive strength and bending resistance of the PVC-U pipe body, prevent the water pipe from deforming or cracking during installation and use, and ensure the normal use of the water pipe.

[0013] Furthermore, the sealing ring is made of silicone rubber, which has good elasticity and aging resistance, ensuring the sealing effect at the joint and preventing condensate leakage.

[0014] (3) Beneficial effects

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: The design effectively improves the wear resistance of the water pipe and extends its service life by setting a wear-resistant layer on the inner wall of the PVC-U pipe. The silicon carbide particles in the wear-resistant layer have high hardness and can resist the wear of impurities in the condensate, while the epoxy resin acts as a bonding agent to fix the silicon carbide particles, ensuring a tight bond between the wear-resistant layer and the PVC-U pipe body. The superhydrophobic layer gives the inner wall of the water pipe a superhydrophobic self-cleaning function; water droplets are difficult to adhere to the surface of the superhydrophobic layer and can quickly roll off, thus carrying away impurities and scale from the inner wall of the water pipe, reducing the frequency of manual cleaning and lowering maintenance costs. The insulation layer prevents condensation on the surface of the water pipe, avoiding a series of problems caused by condensation. The spiral reinforcing ribs enhance the structural strength of the water pipe, making it more stable and reliable during installation and use. The sealing ring on the inner side of the connector ensures the sealing of the water pipe connection and prevents condensate leakage. Attached Figure Description

The inner side of the connector 4 is equipped with a sealing ring 5.

The setting of the superhydrophobic layer 3 gives the inner wall of the pipe superhydrophobic properties, making it difficult for water droplets to adhere, enabling self-cleaning, reducing the adhesion of impurities and scale, reducing the cleaning and maintenance costs of the water pipe, and ensuring the smooth flow of water. The polyurethane foam insulation layer 6 can effectively prevent condensation on the outside of the pipe, reduce energy waste, save users operating costs, and avoid a series of indoor environmental problems caused by condensation on the outside of the pipe.

[0024] The wear-resistant layer 2 has a thickness of 0.3-0.5mm and a particle size of 1-5μm. By uniformly dispersing the fine silicon carbide particles in the epoxy resin, the wear-resistant layer 2 has good wear resistance and impact resistance, and can effectively resist the erosion and wear of impurities in the condensate.

[0025] The thickness of the superhydrophobic layer 3 is 0.1-0.3 mm, and the particle size of the nano-silica particles is 20-100 nm. The fluoropolymer can reduce the surface energy, and the nano-silica particles form a rough structure. The combination of the two gives the superhydrophobic layer 3 excellent superhydrophobic properties. The contact angle of water droplets on the surface of the superhydrophobic layer 3 is greater than 150° and the roll-off angle is less than 10°, which allows condensate to roll off quickly, carrying away impurities attached to the inner wall of the water pipe, realizing a self-cleaning function, keeping the inside of the water pipe clean, and ensuring smooth water flow.

[0026] Insulation layer 6 is a polyurethane foam insulation layer with a thickness of 5-10mm.

Silicon carbide particles with a particle size of 1μm are thoroughly mixed with epoxy resin in a certain proportion, and the mixture is evenly coated onto the inner wall of the PVC-U pipe body 1 using a spraying method to form a wear-resistant layer 2 with a thickness of 0.3mm. After the wear-resistant layer 2 dries and cures, a superhydrophobic layer 3 is coated onto its surface. Nano-silica particles with a particle size of 20nm are evenly mixed with a fluoropolymer, and the mixture is also coated onto the surface of the wear-resistant layer 2 using a spraying method to form a superhydrophobic layer 3 with a thickness of 0.1mm. Finally, a 5mm thick polyurethane foam insulation layer 6 is wrapped around the outer wall of the PVC-U pipe body 1, and the insulation layer 6 is firmly adhered to the outer wall of the PVC-U pipe body 1 using an adhesive. Then, using the same material as the PVC-U pipe body 1, a spiral reinforcing rib 7 with a height of 3mm and a width of 2mm is made and fixed to the outer surface of the insulation layer 6. Connectors 4 are installed at both ends of the PVC-U pipe body 1, and sealing rings 5 ​​made of silicone rubber are embedded inside the connectors to ensure the sealing performance at the connectors 4.
