Description

Technical Field

[0001] This utility model relates to the field of heat tracing pipes, and more specifically, to a quick-release heat tracing pipe. Background Technology

[0002] In industrial production, heat tracing pipes are widely used in petroleum, chemical, and food processing industries. They are mainly used to heat and insulate pipelines that transport easily solidified, high-viscosity media (such as crude oil and syrup) to prevent the media from solidifying and clogging the pipeline or increasing the transport resistance due to excessively low temperatures, thus ensuring the stable operation of the media transport system.

[0003] In the existing technology, the heat tracing elements (such as heating wires, heating belts, etc.) of heat tracing pipes are usually directly fixed to the outer wall of the main pipe by welding, binding with straps, or rigid connection with bolts. Not only is the installation process cumbersome, requiring professional tools and a lot of time, but when the heat tracing elements age or are damaged and need to be repaired or replaced, the disassembly process is also complicated, which can easily cause secondary damage to the main pipe or heat tracing elements, resulting in high maintenance costs.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a quick-release 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 a quick-release heat tracing pipe.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quick-release heat tracing pipe, comprising a main pipe for conveying the medium to be insulated, wherein a heat tracing component is sleeved on the outside of the main pipe; The heat tracing assembly has an inner tube into which the main pipe is inserted. A heat tracing wire is wound around the outer wall of the inner tube. The heat tracing wire is wrapped with an insulation layer. An outer tube is fitted and fixed to the outside of the insulation layer. Wires are connected to both ends of the heat tracing wire. The wires pass through the insulation layer and the outer tube to connect to an external power source. The outer tube and the main tube are detachably connected via a quick-release assembly.

[0007] Preferably, the quick-release assembly includes L-shaped plates fixed to both sides of the outer wall of the outer tube near the end, and the head of each L-shaped plate is fixedly connected to a groove seat. On the outer wall of the main tube, at the corresponding part of the groove seat, there are elastic components that push the protrusions to insert into the groove seats.

[0008] Preferably, the elastic component includes a connecting slot fixed on the outer side wall of the main pipe facing the opening of the groove seat, an inner plate slidably connected inside the connecting slot, a protrusion fixed on the surface of the inner plate facing the groove seat, and a spring installed between the other side of the inner plate and the inner bottom wall of the connecting slot.

[0009] Preferably, both sides of the inner side of the connecting groove are fixedly connected to guide rails for sliding of the sliders, and the inner plate is fixed between the two sliders.

[0010] Preferably, the surface of the connecting slot is provided with a through slot, the surface of the inner plate is fixedly connected with a connecting rod that can extend out of the through slot, and the head of the connecting rod is fixedly connected with a handle.

[0011] Preferably, the inner wall of the inner tube is coated with thermally conductive silicone to enhance the heat transfer efficiency between the inner tube and the main tube.

[0012] Preferably, each groove seat has a through hole, each protrusion is fixedly connected with a screw that can pass through the through hole, and each screw has a nut threadedly connected to its outer side wall.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model achieves quick fixation of the outer tube and the main tube through a quick-release assembly. When components such as the heat tracing wire need to be repaired or replaced, the connection between the outer tube and the main tube can be quickly disconnected through the quick-release assembly, and the heat tracing components can be removed from the main tube. This avoids the cumbersome operation and damage to components caused by traditional connection methods, and achieves a synergy between efficient heat tracing and convenient maintenance, thereby solving the problems in the background technology. 2. The thermally conductive silicone of this utility model can compensate for the assembly gap between the inner tube and the main tube by virtue of its own flexibility, ensuring that the two are always tightly fitted, avoiding heat loss or uneven heat conduction due to the existence of gaps, thereby enhancing the heat conduction efficiency between the inner tube and the main tube; at the same time, the thermally conductive silicone can seal the gap between the two mating surfaces, preventing external dust, moisture and other impurities from entering, and preventing corrosion of the outer wall of the pipe. 3. When the protrusion is inserted into the groove seat, the screw fixed on the protrusion will simultaneously pass through the through hole opened on the groove seat. At this time, the operator can install the nut on the part of the screw that extends out of the through hole and tighten it. Through the abutting action of the nut and the groove seat, the snap-fit ​​structure of the protrusion and the groove seat is fixed for a second time, which effectively prevents the connection of the heat tracing assembly from loosening due to vibration and shaking during the conveying of the medium in the main pipe, and improves the stability of the overall structure.

[0016] like Figure 1-6 As shown, this utility model provides a quick-release heat tracing pipe, including a main pipe 1 for conveying the medium to be insulated, and a heat tracing assembly 2 sleeved on the outside of the main pipe 1; an inner tube 201 into which the main pipe 1 is inserted into the heat tracing assembly 2, a heat tracing wire 202 wound around the outer wall of the inner tube 201, an insulation layer 203 wrapped around the heat tracing wire 202, an outer tube 204 sleeved and fixed on the outside of the insulation layer 203, and wires 205 connected to both ends of the heat tracing wire 202, the wires 205 passing through the insulation layer 203 and the outer tube 204 to connect to an external power source; the outer tube 204 and the main pipe 1 are detachably connected by the quick-release assembly 3.

[0017] When this quick-release heat tracing pipe is in operation, the insulation medium is transported in the main pipe 1. The heat tracing wire 202 generates heat after being connected to an external power source via the wire 205. The heat is transferred to the main pipe 1 through the inner pipe 201 to maintain the temperature of the medium inside the pipe. The insulation layer 203 wraps around the heat tracing wire 202 to reduce heat loss to the outside. The outer pipe 204 protects the insulation layer 203 and the heat tracing wire 202. When the heat tracing component 2 needs to be installed, the main pipe 1 is inserted into the inner pipe 201, and the outer pipe 204 is quickly fixed to the main pipe 1 through the quick-release component 3. When components such as the heat tracing wire 202 need to be repaired or replaced, the connection between the outer pipe 204 and the main pipe 1 can be quickly disconnected through the quick-release component 3, and the heat tracing component 2 can be removed from the main pipe 1. This avoids the cumbersome operation and damage to components caused by traditional connection methods, achieving a synergy between efficient heat tracing and convenient maintenance.

[0018] The inner wall of the inner tube 201 is covered with thermally conductive silicone 4. The thermally conductive silicone 4 can compensate for the assembly gap between the inner tube 201 and the main tube 1 by virtue of its own flexibility, ensuring that the two are always tightly fitted, avoiding heat loss or uneven heat conduction due to the existence of gaps, thereby enhancing the heat conduction efficiency between the inner tube 201 and the main tube 1. At the same time, the thermally conductive silicone 4 can seal the gap between the two mating surfaces, preventing external dust, moisture and other impurities from entering, and preventing corrosion of the outer wall of the pipe.

[0019] The following is the specific structure of the quick-release assembly 3: The quick-release assembly 3 includes L-shaped plates 301 fixed to the outer side wall of the outer tube 204 near the ends. Each L-shaped plate 301 has a groove seat 302 fixedly connected to its head. On the outer side wall of the main tube 1, at locations corresponding to the groove seats 302, elastic components 305 are installed to push protrusions 304 into the groove seats 302. Each elastic component 305 includes a connecting slot seat 3051 fixed to the outer side wall of the main tube 1, opening towards the groove seat 302. An inner plate 3052 is slidably connected inside the connecting slot seat 3051, and the protrusions 304 are fixed to the inner plate. On the surface of the inner plate 3052 facing the groove seat 302, a spring 3054 is installed between the other side of the inner plate 3052 and the inner bottom wall of the connecting groove seat 3051. Guide rails 3055 for sliding sliders 3056 are fixedly connected to both sides of the inner side of the connecting groove seat 3051. The inner plate 3052 is fixed between the two sliders 3056. Through grooves 30511 are opened on the surface of the connecting groove seat 3051. Connecting rods 3057 that can extend from the through grooves 30511 are fixedly connected to the surface of the inner plate 3052. The head of the connecting rods 3057 is fixedly connected to a handle 3053.

[0020] When the heat tracing assembly 2 needs to be installed and fixed on the main pipe 1, the operator presses the inner plate 3052 with the handle 3053 to press the protrusion 304 into the connecting groove 3051. Then, the inner tube 201 is aligned with the main pipe 1 and inserted, so that the groove 302 and the protrusion 304 are aligned. At this time, the handle 3053 is released, and the spring 3054 in the connecting groove 3051 of the elastic component 305 is in a naturally extended state. Its elastic force pushes the inner plate 3052 to move closer to the groove 302. The inner plate 3052 slides smoothly along the guide rails 3055 on both sides of the connecting groove 3051 through the sliders 3056 fixed on both sides, thereby driving the inner plate 3052 to be fixed towards the groove 302. The protrusion 304 is accurately inserted into the groove seat 302, realizing the quick clamping and fixing of the outer tube 204 and the main tube 1, thus completing the installation of the heat tracing component 2. When it is necessary to disassemble the heat tracing component 2, the operator presses the inner plate 3052 again through the handle 3053. The inner plate 3052 compresses the spring 3054 and moves smoothly backward along the guide rail 3055 through the slider 3056, pressing the protrusion 304 back into the connecting groove seat 3051, so that the protrusion 304 is completely removed from the groove seat 302, thereby quickly releasing the fixing relationship between the outer tube 204 and the main tube 1. Then, the inner tube 201 is pulled off the main tube 1, thus completing the disassembly of the heat tracing component 2. The disassembly and assembly are relatively convenient, so that the heat tracing component 2 can be repaired or replaced.

[0021] Furthermore, each groove seat 302 has a through hole 3021, and each protrusion 304 is fixedly connected with a screw 303 that can pass through the through hole 3021. A nut 306 is threaded onto the outer wall of each screw 303. When the protrusion 304 is inserted into the groove seat 302, the screw 303 fixed on the protrusion 304 will simultaneously pass through the through hole 3021 on the groove seat 302. At this time, the operator can install the nut 306 on the part of the screw 303 that extends out of the through hole 3021 and tighten it. Through the abutting action of the nut 306 and the groove seat 302, the protrusion 304 and the groove seat 302 are properly secured. The snap-fit ​​structure of the slot seat 302 forms a secondary fixation, effectively preventing the connection of the heat tracing assembly 2 from loosening due to vibration and shaking during the medium conveying process of the main pipe 1, thus improving the stability of the overall structure. When disassembly is required, first unscrew the nut 306 to release the screw 303 from the constraint, then press the inner plate 3052 with the handle 3053 to make the protrusion 304 and the screw 303 exit from the slot seat 302 and the through hole 3021, and then pull the inner tube 201 off the main pipe 1 to complete the disassembly. While ensuring quick disassembly and assembly, the connection reliability is enhanced by the cooperation between the screw 303 and the nut 306.
