Description

Technical Field

[0001] This utility model relates to the field of heat tracing pipes, and more specifically, to an adjustable heat tracing pipe. Background Technology

[0002] In many industrial sectors, such as petrochemicals, pharmaceuticals, and food processing, there are often pipelines that transport fluids. These fluids need to be maintained within a certain temperature range during transport to prevent solidification, increased viscosity, or changes in condition that are detrimental to the production process. Heat tracing pipes have emerged to address this need. By being closely fitted or placed near the main pipeline, they utilize a heat medium (such as steam or hot water) flowing within the pipe to provide heat to the main pipeline, thereby achieving functions such as insulation and heating.

[0003] However, in early pipeline system designs, the installation of heat tracing pipes focused primarily on basic heat tracing functionality, with insufficient consideration given to potential future adjustments. This resulted in difficulties in easily adjusting the spacing and fit between the existing heat tracing pipes and the pipes requiring heat tracing. If the spacing is too large or the fit is not tight, air will fill the gaps, increasing thermal resistance and requiring more obstacles for heat transfer. Heat will easily dissipate into the surrounding environment rather than being effectively transferred to the heat tracing pipe. For example, in cold outdoor oil pipeline heat tracing scenarios, excessive spacing will cause a significant amount of heat to dissipate into the air, failing to adequately heat the oil inside the pipe. A loose fit reduces the effective contact area. Heat transfer is positively correlated with contact area; a smaller area results in less heat transfer, and even tiny air gaps can form a heat transfer barrier. In chemical material transport pipeline heat tracing, a loose fit leads to unstable and inefficient heat transfer, causing material temperature fluctuations and affecting product quality and production processes.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes an adjustable heat tracing pipe. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable heat tracing pipe.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable heat tracing pipe, comprising a heat tracing pipe body, a heat-conducting shell sleeved on the outer wall of the heat tracing pipe body, the heat-conducting shell being connected to a heat-conducting plate around its perimeter by heat-conducting telescopic rods, the height of the heat-conducting telescopic rods being fixed by screws, heat conduction through contact between the heat-conducting plate and the pipe to be heat-traced, and a compressible heat-conducting silicone pad being installed between the heat-conducting plate and the heat-conducting shell.

[0007] Preferably, the heat tracing pipe body is composed of multiple steam conveying pipes, and the space between the conveying pipes and between the conveying pipes and the heat-conducting shell is filled with a heat-conducting material.

[0008] Preferably, the thermally conductive material is magnesium oxide, which can effectively transfer heat from the conveying pipe to the thermally conductive shell.

[0009] Preferably, the thermally conductive telescopic rod includes an outer shell fixed to the outer wall of the thermally conductive shell, an inner block slidably connected inside the outer shell, a vertical rod extending from the top slot of the thermally conductive shell fixedly connected to the head of the inner block, and a silicone rubber pad bonded between the vertical rod and the thermally conductive plate.

[0010] Preferably, the inner block has a plurality of screw holes arranged in a vertical array on its side for screw installation, and the outer shell has a through hole for screws to pass through on its side.

[0011] Preferably, the contact surface between the heat-conducting plate and the pipe requiring heat tracing is designed with a corresponding arc shape, so that the two can make close contact.

[0012] Preferably, the heat-conducting shell and the heat-conducting telescopic rod are made of aluminum, which has good thermal conductivity.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model can conveniently adjust the distance and tightness of the fit between the heat tracing pipe and the pipe to be heat-traced by means of telescoping and fixing, while ensuring stable heat conduction, thereby solving the problem that the distance and tightness of the fit between the heat tracing pipe and the pipe to be heat-traced in the existing technology are difficult to adjust conveniently.

[0015] 2. In this utility model, a silicone rubber pad is bonded between the vertical rod and the heat-conducting plate. The silicone rubber pad has excellent thermal conductivity, which allows heat to be stably transferred from the heat-conducting telescopic rod to the heat-conducting plate. At the same time, it also has a certain degree of elasticity. When the heat-conducting plate comes into contact with the pipe that needs to be heated, the silicone rubber pad will be squeezed, thereby forming a rebound force, which allows the heat-conducting plate to make more reliable contact with the pipe that needs to be heated.

[0016] 3. The main body of the heat tracing pipe of this utility model is composed of multiple steam conveying pipes. In this way, when a single conveying pipe fails, such as leakage or blockage, the other normal conveying pipes can still continue to provide some heat and maintain a certain heat tracing capacity, so as not to cause the entire heat tracing system to fail immediately. This gives maintenance personnel time to troubleshoot and repair the fault, thereby improving the reliability and stability of the entire heat tracing system in long-term operation.

[0024] like Figure 1-4 As shown, this utility model provides an adjustable heat tracing pipe, including a heat tracing pipe body 1, a heat-conducting shell 2 sleeved on the outer wall of the heat tracing pipe body 1, and heat-conducting shell 2 connected to heat-conducting plate 4 by heat-conducting telescopic rods 3 on all four sides. The height of the heat-conducting telescopic rods 3 is fixed by screws. Heat is conducted through the contact between the heat-conducting plate 4 and the pipe to be heated. A compressible heat-conducting silicone pad 5 is installed between the heat-conducting plate 4 and the heat-conducting shell 2.

[0025] In use, by pulling the heat-conducting plate 4 back and forth, the heat-conducting telescopic rod 3 and the compressible heat-conducting silicone pad (the biggest feature of this type of silicone pad is its high compressibility; it can easily change its thickness under external force and return to its initial state when the external force is removed, possessing good elasticity and excellent thermal conductivity) extend and retract accordingly, allowing the heat-conducting plate 4 to fit tightly against the pipe that needs heat tracing. Then, the length of the heat-conducting telescopic rod 3 is fixed with screws. At this time, the heat from the heat-tracing pipe body 1 is transferred to the heat-conducting telescopic rod 3 and the compressible heat-conducting silicone pad 5 through the heat-conducting shell 2, and then transferred by the two to the heat-conducting plate 4 (stable heat conduction), thereby tracing the pipe that is in contact with the heat-conducting plate 4. This method of extension and re-fixing allows for convenient adjustment of the distance and tightness of contact between the heat-tracing pipe and the pipe that needs heat tracing. It should be noted that after the heat-tracing pipe has completed thermal contact with multiple pipes that need heat tracing, the insulation cotton needs to be wrapped together to prevent heat loss.

[0026] The heat-conducting shell 2 and the heat-conducting telescopic rod 3 are made of aluminum, which has excellent thermal conductivity. At the same time, aluminum has a low density, which allows the aluminum heat-conducting shell 2 and heat-conducting telescopic rod 3 to be lighter while maintaining certain thermal conductivity, thus reducing the load on the heat tracing pipe. Furthermore, this invention designs the contact surface between the heat-conducting plate 4 and the pipe requiring heat tracing with a corresponding arc shape, thereby ensuring close contact between the two.

[0027] Furthermore, this utility model also provides the specific structure of the heat-conducting telescopic rod 3: the heat-conducting telescopic rod 3 includes an outer shell 301 fixed on the outer wall of the heat-conducting shell 2, an inner block 302 slidably connected inside the outer shell 301, a vertical rod 303 extending from the top slot of the heat-conducting shell 2 fixedly connected to the head of the inner block 302, and a silicone rubber pad 6 bonded between the vertical rod 303 and the heat-conducting plate 4.

[0028] When the thermally conductive telescopic rod 3 extends or retracts, the vertical rod 303 will drive the inner block 302 to move up and down along the inside of the outer shell 301. It should be noted that the cross-section of the inner block 302 is the same as the internal cross-section of the thermally conductive shell 2. It can move in a straight line along the inside of the thermally conductive shell 2 and make stable contact with the outer shell 301 (the outer shell 301, the vertical rod 303 and the inner block 302 are all made of aluminum). The side end of the inner block 302 has multiple screw holes 304 arranged in a vertical array for screw installation. The side end of the outer shell 301 has through holes 305 for screws to pass through. After the length of the thermally conductive telescopic rod 3 is determined, the screw is inserted into the screw hole 304 on the inner block 302 by passing through the corresponding height through hole 305 and then rotating clockwise, so as to complete the fixation of the length of the thermally conductive telescopic rod 3.

[0029] Furthermore, a silicone rubber pad 6 is bonded between the vertical rod 303 and the heat-conducting plate 4. The silicone rubber pad 6 has excellent thermal conductivity, which allows heat to be stably transferred from the heat-conducting telescopic rod 3 to the heat-conducting plate 4. At the same time, it also has a certain degree of elasticity. When the heat-conducting plate 4 comes into contact with the pipe that needs to be heated, the silicone rubber pad 6 will be squeezed, thereby forming a rebound force, which allows the heat-conducting plate 4 to make more reliable contact with the pipe that needs to be heated.

[0030] The main body 1 of the heat tracing pipe consists of multiple steam conveying pipes 101. The space between the conveying pipes 101 and between them and the heat-conducting shell 2 is filled with a heat-conducting material. In actual operation, if a single conveying pipe 101 experiences a fault such as leakage or blockage, the remaining normal conveying pipes 101 can still continue to provide some heat and maintain a certain heat tracing capacity, preventing the entire heat tracing system from failing immediately. This gives maintenance personnel time to troubleshoot and repair the fault, thereby improving the reliability and stability of the entire heat tracing system in long-term operation. The heat-conducting material is magnesium oxide, which is a high-performance heat-conducting material with a high thermal conductivity. It can effectively transfer the heat in the conveying pipes 101 to the heat-conducting shell 2.

Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
