Description

TECHNICAL FIELD

[0002] As an indispensable transportation equipment in the petroleum and chemical industry, sticky oil tank cars are widely used in the loading and unloading operations of viscous chemical media such as crude oil, heavy diesel oil, and lubricating oil. These tank cars usually adopt a top-loading and bottom-unloading mode to adapt to different medium characteristics and operational requirements. However, in actual application, the high viscosity characteristics of sticky oil often result in low efficiency during the unloading process, becoming one of the key factors restricting transportation efficiency. Therefore, to solve this problem, the industry generally adopts the method of installing a heating device in the sticky oil tank car.

[0003] This heating device is based on the thermal boundary layer drag reduction principle, which applies heat to the outer wall of the liquid flow container, significantly increasing the temperature of the thin layer of fluid close to the wall, thereby reducing the fluid viscosity in this area. This measure effectively reduces the frictional loss of the liquid during the flow process, significantly improves the unloading speed of sticky oil, and ensures that the sticky oil in the tank body can be unloaded as completely as possible, avoiding residual problems.

[0004] However, the connection method of the steam inlet pipe structure in the existing sticky oil tank car heating system with the tank body and other components is very complex, involving numerous fittings, which not only increases the assembly difficulty, but also easily interferes with the surrounding lifting structure during assembly, affecting the overall installation efficiency and safety. In addition, due to the large number of connections, not only does it increase the complexity of the manufacturing process, but it also increases the risk of leakage, leading to increased heat loss, rising energy consumption, and potential threats to operational safety.

[0005] Therefore, to solve the problem of complex connection structure of the steam inlet pipe in the existing sticky oil tank car heating system, which is prone to interference and affects safety, and also has a risk of leakage, it is now necessary to provide a sticky oil tank car steam inlet pipe structure.

[0025] The following detailed description illustrates the specific implementation method:

[0026] Example 1

[0027] This embodiment is basically as shown in the appendix. Figure 1 As shown: A steam inlet pipe structure for an oil tanker truck. By simplifying the steam inlet pipe connection structure, the number of accessories can be effectively reduced, thereby lowering the installation difficulty. At the same time, the number of joints is significantly reduced, thus lowering the risk of leakage at the joints. Furthermore, the improved steam inlet pipe connection structure cleverly avoids interference with the lifting bracket 7, ensuring safety and simplifying the manufacturing process. Specifically, the steam inlet pipe connection structure is shown in the attached figure. Figure 2As shown, including with the first heating tank 1 and steam inlet end 2 connected to the reducing tee 3, in this embodiment, the first port of the reducing tee 3 is connected to the first heating tank 1, and the second port of the reducing tee 3 is connected to the steam inlet end 2, so that the steam enters from the steam inlet end 2. At the outlet end of the reducing tee 3, i.e. the third port, an internal socket joint 5 is provided for connecting different parts of the pipeline system, facilitating the installation, disassembly and maintenance of the pipeline, while being able to adapt to a certain degree of pipeline displacement and deformation, ensuring the sealing and flexibility of the pipeline system.

[0028] The output end of the internal socket joint 5 is connected to the steam inlet pipe 4, so that the connection position is convenient to operate while ensuring the stability and flexibility of the connection. The connection end of the steam inlet pipe 4 is connected to the first heating tank 1 as shown in the attached Figure 1 As shown, a 60° angle is formed for installation arrangement. In this embodiment, the steam inlet pipe 4 is a galvanized pipe, which effectively improves the corrosion resistance and has lower production cost. It ensures the stability of the steam inlet pipe and prolongs the service life, while also ensuring the stability of the gas pressure in the pipe to avoid safety accidents and ensure the stable and safe operation of the heating system.

[0029] In this embodiment, in order to ensure that the steam inlet pipe 4 meets the installation arrangement in the heating system without affecting the structure of other components, the steam inlet pipe 4 is arranged in a U-shaped structure with gradually expanding openings, and the openings are directed towards the side of the tank 6 during installation. As shown in the attached Figure 3 As shown, the steam inlet pipe 4 includes a first pipe segment 41, a second pipe segment 42 and a third pipe segment 43 connected integrally. The angle between the first pipe segment 41 and the second pipe segment 42 is 120°, and the angle between the second pipe segment 42 and the third pipe segment 43 is 120°. This ensures smooth flow of fluid between the pipe segments, avoids accumulation and blockage at the bend, and reduces the risk of accumulation. At the same time, the use of large-radius bend corner design also allows the steam inlet pipe 4 to be directly arranged in one piece, thereby reducing the number of fittings at the bend, ensuring smooth flow of steam while reducing the number of joints, thereby reducing the number of fittings and avoiding the risk of leakage at the joint, improving heating efficiency and reducing energy loss, effectively improving the efficiency of oil removal.

[0030] In this embodiment, the second pipe segment 42 is inclined to one side of the tank 6, and the distance between the second pipe segment 42 and the tank 6 is 220-300mm. The angle between the first pipe segment 41 and the second pipe segment 42 is a round corner with a radius of 150-200mm. The angle between the second pipe segment 42 and the third pipe segment 43 is a round corner with a radius of 150-200mm. This ensures the heating effect of the steam, while avoiding interference between the steam inlet pipe and the hangers 7 around the tank 6, affecting the overall installation and safety, and arranging the steam inlet pipe 4 in a large round corner shape to further increase the distance between the steam inlet pipe and the hangers 7 at the bend, thereby effectively avoiding interference.

[0031] In the embodiment, the first pipe section 41 has a length smaller than that of the third pipe section 43, and the third pipe section 43 has a height of 160-190 mm. The first pipe section 41 can be smoothly connected to the inner socket joint 5, and the horizontal length of the second pipe section 42 is 550-580 mm. As shown in the attached Figure 4 figure, the inlet end of the second pipe section 42 is slightly lower, and the height difference between the two ends of the second pipe section 42 is 8-10 mm, specifically, the left end is 10 mm lower than the right end, which facilitates the flow of water vapor and avoids interference with surrounding parts.

[0032] An inner socket elbow 8 is installed at the output end of the steam inlet pipe 4, i.e., the third pipe section 43 is connected to the inner socket elbow 8, and the inner socket elbow 8 is connected to the inlet end of the second heating tank 9. That is, the steam inlet pipe 4 is directly connected to the inlet end of the second heating tank 9 through the inner socket elbow 8, and the angle between the output end of the steam inlet pipe 4 and the second heating tank 9 is 120°. This greatly reduces the complexity of the connection structure of the steam inlet pipe 4, reduces the number of required fittings, effectively reduces the number of joints, thereby avoiding the risk of leakage, improving the heating efficiency and safety.

[0033] In the embodiment, the steam inlet pipe is integrally formed, which can complete the connection and installation of the steam inlet pipe structure, simplify the structure, reduce the number of required fittings, reduce the types of fittings by half, directly reduce the number of joints from the original 9 to 4, greatly reduce the installation difficulty, reduce the risk of joint leakage, and ensure safety. And its processing and manufacturing are easier, and the production cost is lower. The designed steam inlet pipe structure can ensure the heating effect of the heating system, effectively increase the distance between the steam inlet pipe and the hanger, avoid interference between them, and ensure stable and safe use.

[0034] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should be considered as the protection scope of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
