Description

Technical Field

[0001] This utility model relates to the field of energy transmission pipeline technology, and in particular to a large temperature difference energy transmission pipeline device. Background Technology

[0002] Energy transmission pipelines refer to pipeline systems used to transport energy. The main function of energy transmission pipelines is to transport energy from production sites or processing plants to urban gas distribution centers or industrial users to ensure a stable energy supply. At the same time, transmission pipelines can withstand large temperature changes, so a large temperature difference energy transmission pipeline device is used.

[0003] Therefore, patent CN221723603U discloses a gas transmission pipeline, relating to the field of pipeline technology. This utility model includes a pipeline assembly, the interior of which is provided with a flow guide component to support and guide airflow. The surface of the pipeline assembly is provided with a detection and venting component to detect the gas concentration at the flow guide component. A connecting component is fixedly installed at one end of the pipeline assembly. This utility model uses a gas detection element to detect the airflow at the flow guide component. If an accident occurs, causing a leak in the inner pipeline body and gas entering the flow guide component, the leak can be detected promptly, improving the safety of equipment use. Connecting the extraction device to the auxiliary connecting pipe allows residual gas to be cleared before pipeline repair work, assisting workers in maintenance. A protective cover protects the connecting component, preventing blockage, corrosion, or damage caused by the pipeline installation environment.

[0004] Although the gas transmission pipelines mentioned above avoid the installation environment from causing blockage, corrosion, or damage to the connecting components, their applicability is low because they are inconvenient to filter impurities in the gas and protect the pipeline from blockage or wear. Utility Model Content

[0005] The purpose of this invention is to provide a large temperature difference energy transmission pipeline device to solve the problem of inconvenient filtration in existing large temperature difference energy transmission pipeline devices.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a large temperature difference energy transmission pipeline device, including a pipeline body;

[0007] Flanges are fixed at both ends of the pipe body, and an insulation structure is installed on the outside of the pipe body.

[0008] A protective structure is provided at one end of the inner side of the pipe body, and a filter structure is provided at the other end of the inner side of the pipe body;

[0009] The filter structure includes an installation groove at one end of the inner side of the pipe body, a fixing frame is provided on one side of the installation groove, a filter screen is fixed on one side of the fixing frame, and positioning grooves are evenly provided inside the pipe body on the other side of the fixing frame.

[0010] When using this device, the filter structure facilitates anti-clogging, thereby improving the applicability of the large temperature difference energy transmission pipeline device; the insulation structure facilitates heat preservation, thereby improving the convenience of use; and the protective structure facilitates corrosion prevention, thereby extending the service life of the large temperature difference energy transmission pipeline device.

[0011] Preferably, a first magnetic block is fixed to one end of each positioning groove, a second magnetic block is provided on one side of each first magnetic block, and a positioning post is fixed to one side of each second magnetic block. Under the action of the filter screen, impurities and particles in the gas can be filtered out, ensuring the purity of the gas, reducing wear and blockage of the pipeline body, and reducing resistance to gas flow.

[0012] Preferably, one end of the filter screen extends to the outside of the pipe body, and one end of the positioning post extends into the interior of the mounting groove and is fixedly connected to one side of the fixing frame. Under the action of the first and second magnetic blocks, the filter screen and the pipe body are fixed or separated to facilitate cleaning of the filter screen.

[0013] Preferably, the insulation structure includes a polyethylene sheath, a temperature sensor, an electric heating tape, a pressure-sensitive adhesive tape, an aluminum foil layer, and a sealing ring. The electric heating tape is disposed on both sides of the pipe body. Pressure-sensitive adhesive tape is uniformly adhered to the outer side of the electric heating tape, and an aluminum foil layer is disposed on the outer side of each pressure-sensitive adhesive tape. A polyethylene sheath is disposed on the outer side of each aluminum foil layer. Sealing rings are fixed to the outer sides of the pipe body at both ends of the electric heating tape. A temperature sensor penetrates through the top of the pipe body at one end of the electric heating tape. By fixing the electric heating tape to the outer side of the pipe body using pressure-sensitive adhesive tape, the pipe body can be heated under the action of the electric heating tape. The aluminum foil layer helps to distribute the heat generated by the electric heating tape more evenly across the entire surface of the pipe body, avoiding localized overheating or uneven heating.

[0014] Preferably, the top of the sealing ring is fixedly connected to the inner side of the aluminum foil layer, and the output end of the temperature sensor is electrically connected to the input end of the electric heating tape via a microcontroller. The polyethylene sheath provides excellent waterproof and moisture-proof performance, preventing corrosion of the aluminum foil layer and short circuits in the electric heating tape. The sealing ring enhances the sealing performance. The temperature sensor can monitor the internal temperature of the pipeline in real time. When the temperature reaches a preset value, the temperature sensor, via the microcontroller, controls the electric heating tape to stop heating, thereby preventing the gas inside the pipeline from freezing, icing, or becoming less fluid due to low temperatures.

[0015] Preferably, the protective structure includes a drag-reducing coating, an anti-corrosion coating, and an epoxy resin coating. The epoxy resin coating is fixed to one end of the inner side of the pipe body. An anti-corrosion coating is disposed on the inner side of the epoxy resin coating, and a drag-reducing coating is disposed on the inner side of the anti-corrosion coating. Due to the high adhesion and hardness of the epoxy resin coating, it can effectively prevent moisture and other chemical substances from corroding the pipe body. The anti-corrosion coating forms a continuous and dense protective film on the inner wall of the pipe body, effectively isolating corrosive media such as moisture and oxygen, and preventing corrosion of the pipe body.

[0016] Preferably, the drag-reducing coating is actually a polytetrafluoroethylene coating, and the anti-corrosion coating is actually a polyurethane coating. Under the action of the drag-reducing coating, the frictional resistance of the gas within the pipeline body can be significantly reduced, improving transmission efficiency and reducing energy consumption.

[0017] The advantages of the large temperature difference energy transmission pipeline device provided by this utility model are as follows:

[0018] By incorporating a filtration structure, the filter screen can remove impurities and particles from the gas, ensuring its purity and reducing wear and blockage of the pipeline body. It also reduces the resistance to gas flow. Under the action of the first and second magnetic blocks, the filter screen and the pipeline body can be fixed or separated, facilitating the cleaning of the filter screen. This device achieves the function of easy anti-clogging, thereby improving the applicability of the large temperature difference energy transmission pipeline device during use.

[0019] By incorporating an insulation structure and fixing the electric heating cable to the outside of the pipe body using pressure-sensitive adhesive tape, the electric heating cable heats the pipe body. The aluminum foil layer further distributes the heat generated by the heating cable evenly across the entire pipe surface, preventing localized overheating or uneven heating. The polyethylene sheath provides excellent waterproof and moisture-proof properties, preventing corrosion of the aluminum foil layer and short circuits in the electric heating cable. A sealing ring enhances the sealing performance. A temperature sensor monitors the internal temperature of the pipe body in real time. When the temperature reaches a preset value, the sensor, via a microcontroller, stops the heating of the electric heating cable, preventing the gas inside the pipe from freezing, icing, or becoming less fluid due to low temperatures. This device facilitates insulation and improves the ease of use of this large temperature difference energy transmission pipeline system.

[0020] By incorporating a protective structure and utilizing the high adhesion and hardness of the epoxy resin coating, the system effectively prevents moisture and other chemicals from corroding the pipeline body. The anti-corrosion coating forms a continuous and dense protective film on the inner wall of the pipeline, effectively isolating corrosive media such as moisture and oxygen, thus preventing corrosion. Furthermore, the drag-reducing coating significantly reduces the frictional resistance of the gas within the pipeline, improving transmission efficiency and reducing energy consumption. This system facilitates corrosion protection and extends the service life of the large temperature difference energy transmission pipeline. Attached Figure Description

At this time, the fixed frame 303 drives the second magnetic block 306 to abut against the first magnetic block 305 through the positioning post 307. Under the action of the first magnetic block 305 and the second magnetic block 306, the filter screen 302 and the pipe body 1 are fixed to each other. Under the action of the filter screen 302, impurities and particles in the gas can be filtered out, ensuring the purity of the gas, reducing the wear and blockage of the pipe body 1, and reducing the resistance to gas flow. Moving the filter screen 302 causes the positioning post 307 to drive the second magnetic block 306 to separate from the first magnetic block 305. At this time, the filter screen 302 is separated from the pipe body 1, making it convenient to clean the filter screen 302.
