[0016] It should be noted that, unless otherwise defined, the technical or scientific terms used in this application shall have the ordinary meaning as understood by a person with ordinary skills in the field to which this application pertains.
[0017] In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0018] In related technologies, armored heating cables and insulation structures are usually installed outside the pipeline to heat and insulate the pipeline. However, due to the poor fit between the armored heating cable and the pipeline, the temperature of the armored heating cable is too high when heating the pipeline, which affects the service life of the armored heating cable. Furthermore, when the armored heating cable is damaged, the installation and replacement process is relatively cumbersome, requiring disassembly and reinstallation layer by layer.
[0019] To address the aforementioned technical problems, embodiments of this application provide a pipe heating assembly. Figure 1 This is a schematic diagram of the structure of a pipe heating assembly according to an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a pipe heating assembly according to another embodiment of this application, as shown below. Figure 1 and Figure 2 As shown, the pipe heating assembly 100 may include at least: a heating element 110, an insulation element 120, and a housing 130.
[0020] In some embodiments, the heating element 110 is configured to heat the pipe and deform under the action of an external force to cover the pipe; the heat insulation element 120 is disposed on the heating element 110 and configured to keep the heating element 110 warm; the housing 130 is disposed outside the heating element 110 and the heat insulation element 120 and configured to apply an external force to the heating element 110 and the heat insulation element 120 so that the heating element 110 covers the pipe.
[0021] The pipe heating assembly 100 provided in the embodiments of this application has a heating element 110 that can deform under the action of external force. This is beneficial to improve the fit between the heating element 110 and the pipe. Compared with the traditional method of heating the pipe, it can avoid the situation where the heating element 110 is too hot due to the low fit between the heating element 110 and the pipe, which affects its service life. This is beneficial to improve the service life of the heating element 110 and the heating efficiency of the pipe. Furthermore, the insulation element 120 is set on the heating element 110, and the housing 130 is set on the outside of the heating element 110 and the insulation element 120. The heating element 110, the insulation element 120 and the housing 130 can be installed and disassembled as a whole, and the installation and replacement operations are relatively simple.
[0022] In some embodiments, the material of the housing 130 may be stainless steel or the like, and this application does not limit this.
[0023] In some embodiments, Figure 3 This is a partial structural schematic diagram of the heating element according to an embodiment of this application, such as... Figure 3 As shown, the heating element 110 includes a heating part 111 and a heating fixing part 112. The heating part 111 is configured to heat the pipe. The heating fixing part 112 is configured to fix the heating part 111 and cover the heating part 111. The heating fixing part 112 is also configured to deform under the action of external force so that the heating part 111 fits the pipe.
[0024] The pipe heating assembly 100 of this application has a structure in which the heating element 110 includes a heating part 111 and a heating fixing part 112. The heating part 111 is fixedly covered by the heating fixing part 112. This allows the heating part 111 to be subjected to a force by the heating fixing part 112, thereby making the heating part 111 fit the pipe. This helps to further improve the fit between the pipe and the heating part 111. In addition, the heating fixing part 112 can also provide support for the heating part 111. This eliminates the need for additional support members to support the heating part 111, such as the need for additional support members with a keel structure. It also avoids the situation where the heat dissipation increases due to the additional support members.
[0025] In some embodiments, the heating element 111 may be an electric heating wire. In such embodiments, the connector of the electric heating wire may be mounted on the housing 130 to allow for field wiring during use.
[0026] In some embodiments, the connector of the electric heating wire can be an aviation plug to improve the convenience of plugging and unplugging operations, and the aviation plug has a high installation density and good sealing performance after being connected to the electric heating wire.
[0027] In some embodiments, the heating fixing part 112 can be a wire mesh to reduce the transfer of heat to the heat insulation member 120.
[0028] In some embodiments, Figure 4 yes Figure 3 The schematic diagram of a partial cross-sectional structure of the heating element 110 shown is as follows: Figure 3 and Figure 4 As shown, a heating receiving groove 1120 is formed on the heating fixing part 112, and the heating part 111 is disposed in the heating receiving groove 1120, which can improve the fixing effect of the heating part 111, prevent the heating part 111 from separating from the pipeline after heating expansion, and further ensure that the heating part 111 can stay in close contact with the pipeline, thereby ensuring the stability and safety of the heating part 111 when heating the pipeline.
[0029] In some embodiments, the outer diameter of the heating receiving groove 1120 may be set to be slightly larger than the outer diameter of the heating part 111 in order to ensure the fixing effect of the heating part 111.
[0030] In some embodiments, there are multiple heating receiving grooves 1120, which are arranged along the axial direction of the pipe to further improve the fixing effect on the heating part 111.
[0031] It can be understood that the multiple heating receiving tanks 1120 are arranged along the axial direction of the pipeline, which means that multiple heating receiving tanks 1120 are spaced apart along the axial direction of the pipeline, and each heating receiving tank 1120 is arranged along the circumference of the pipeline, so that the heating part 111 arranged in the multiple heating receiving tanks 1120 can be wrapped around the pipeline.
[0032] In some embodiments, such as Figure 4 As shown, the heating receiving tank 1120 includes a plurality of first receiving portions 11201 and a plurality of second receiving portions 11202. The second receiving portions 11202 are disposed between two adjacent first receiving portions 11201 to securely fix the heating portion 111.
[0033] In some embodiments, such as Figure 4 As shown, the heating fixing part 112 may include a heating fixing body 1121 and a fixing connection part 1122, with two adjacent heating fixing bodies 1121 connected by the fixing connection part 1122. In such an embodiment, under the action of external force, the fixing connection part 1122 can apply a force to the heating fixing body 1121, thereby causing the heating fixing body 1121 to conform to the pipe.
[0034] In some embodiments, such as Figure 3 and Figure 4 As shown, a first receiving portion 11201 is formed on the heating and fixing body 1121. A second receiving portion 11202 is formed on the fixing connection portion 1122.
[0035] In some embodiments, the cross-section of the second receiving portion 11202 is set to be arc-shaped along the axial direction of the pipe to ensure that the heating portion 111 can be stably disposed in the second receiving portion 11202.
[0036] In some embodiments, the fixing connection portion 1122 of the heating fixing portion 112 may be configured such that its cross-section is arc-shaped along the axial direction of the pipe. In such an embodiment, the heating receiving groove 1120 may be configured as an Ω-groove.
[0037] In some embodiments, such as Figure 1 As shown, the heat insulation component 120 includes a first heat insulation part 121 and a second heat insulation part 122. The first heat insulation part 121 is disposed between the heating component 110 and the second heat insulation part 122. The first heat insulation part 121 is configured to reduce the transfer of heat generated by the heating component 110 to the housing 130. The second heat insulation part 122 is configured to keep the heating component 110 warm.
[0038] The pipe heating assembly 100 provided in the embodiments of this application has an insulation component 120 configured to include a first insulation part 121 and a second insulation part 122. The first insulation part 121 can be used to reduce the transfer of heat generated by the heating component 110 to the housing 130, and the second insulation part 122 is also provided to keep the heating component 110 warm. This can improve the heat preservation effect of the heating component 110 and prevent burns to workers.
[0039] In some embodiments, the first heat-insulating part 121 may be disposed between the heating fixing part 112 and the second heat-insulating part 122 of the heating element 110.
[0040] In some embodiments, the transfer of heat generated by the heating element 110 to the housing 130 can be reduced by decreasing the area between the first heat-insulating part 121 and the heating fixing part 112.
[0041] In some embodiments, the material of the second insulation portion 122 can be any material capable of achieving insulation, such as aluminum silicate. In such embodiments, the insulation component 120 further includes an isolation portion disposed between the first insulation portion 121 and the second insulation portion 122, and configured to isolate debris generated by the second insulation portion 122, preventing debris from scattering and causing environmental pollution and damage to the respiratory health of workers.
[0042] In some embodiments, the insulating part can be a fiber cloth to ensure the isolation effect on debris.
[0043] In some embodiments, the first heat-insulating part 121 is configured to have a plurality of openings in order to reduce the transfer of heat generated by the heating element 110 to the housing 130.
[0044] Embodiments of this application also provide a pipe heating device. Figure 5 This is a schematic diagram of the structure of a pipe heating device according to an embodiment of this application. Figure 6 yes Figure 5 The exploded structural diagram of the pipe heating device shown is as follows: Figure 5 and Figure 6 As shown, the pipe heating device includes at least the pipe heating component 100, the temperature measuring component 200, and the detection component 300 according to the embodiments of this application.
[0045] In some embodiments, the pipe heating assembly 100 is configured to heat pipe fittings and insulate the pipe; the temperature measuring assembly 200 is configured to measure the temperature of the pipe; and the detection assembly 300 is configured to detect leaked liquid medium in the pipe; wherein the temperature measuring assembly 200 and the detection assembly 300 are respectively disposed in the pipe heating assembly 100.
[0046] The pipeline heating device provided in the embodiments of this application can heat and insulate the pipeline. During the heating process, the temperature measuring component 200 can measure the temperature of the pipeline for online monitoring. At the same time, the detection component 300 can detect whether the liquid medium in the pipeline is leaking, thereby ensuring the safe operation of the pipeline. The temperature measuring component 200 and the detection component 300 are respectively set in the pipeline heating component 100. When maintenance or replacement is required, the temperature measuring component 200, the detection component 300 and the pipeline heating component 100 can be disassembled and reassembled as a whole, which is relatively simple to operate.
[0047] In some embodiments, Figure 7 This is a schematic diagram of the structure of a temperature measuring component according to an embodiment of this application, as shown below. Figure 7 As shown, the temperature measuring component 200 includes a measuring element 210, an elastic element 220, and a measuring fixing element 230. The measuring element 210 is fixedly mounted on the pipe heating component 100 by the measuring fixing element 230 and is used to measure the temperature of the pipe. The elastic element 220 is configured to press the measuring element 210.
[0048] The pipeline heating device provided in the embodiments of this application uses a measuring fixing member 230 to fix the measuring member 210, and then uses an elastic member 220 to press the measuring member 210. This can accurately position the measuring member 210 and help ensure that the measuring member 210 stays close to the pipeline surface when the pipeline vibrates, thereby ensuring the reliability of the temperature measurement results obtained by the measuring member 210.
[0049] In some embodiments, such as Figure 7As shown, the measuring fixture 230 includes an auxiliary fixing part 231, a first fixing part 232, and a second fixing part 233. The second fixing part 233 is disposed on the first fixing part 232 and forms a measuring receiving cavity 201. The elastic member 220 and the auxiliary fixing part 231 are disposed within the measuring receiving cavity 201, and the auxiliary fixing part 231 is configured to abut against the first fixing part 232 under the action of the elastic member 220. The measuring member 210 is configured to pass through the second fixing part 233, the first fixing part 232, and the auxiliary fixing part 231. In this embodiment, when the measuring member 210 moves, the elastic member 220 can apply a force to the auxiliary fixing part 231, thereby keeping the auxiliary fixing part 231 abutting against the first fixing part 232, thus restricting the movement of the measuring member 210. The measuring member 210 can remain close to the pipe surface when the pipe vibrates.
[0050] In some embodiments, such as Figure 7 As shown, the temperature measuring component 200 may also include a heat-conducting element 240, which is disposed between the measuring element 210 and the pipe and is configured to increase the contact surface between the measuring element 210 and the pipe, thereby further improving the temperature measuring effect of the measuring element 210.
[0051] In some embodiments, Figure 8 This is a side view of the pipe heating assembly before connection according to an embodiment of this application. Figure 9 yes Figure 8 The diagram shows the side structure of the pipe heating assembly after connection, as shown below. Figures 5 to 9 As shown, there are multiple pipe heating components 100. One pipe heating component 100 is configured to be detachably connected to another pipe heating component 100 so that the entire pipe heating component 100 can be easily disassembled when it is necessary to replace or repair the pipe heating component 100.
[0052] In some embodiments, such as Figure 5 and Figure 9 As shown, when one pipe heating assembly 100 is connected to another pipe heating assembly 100, a pipe receiving cavity 101 can be formed, and the pipe is disposed in the pipe receiving cavity 101.
[0053] In some embodiments, such as Figure 8 and Figure 9 As shown, along the axial direction of the pipe, the cross-section of one pipe heating component 100 is set as concave, and the cross-section of the other pipe heating component 100 is set as convex.
[0054] In some embodiments, along the axial direction of the pipe, one of the cross-sections of the two pipe heating components 100 is set as a concave surface and the other as a convex surface. In this way, the cooperation between the concave and convex cross-sections can keep the pipe warm when the pipe expands due to heat and a gap is generated, thereby reducing the heat loss of the pipe. At the same time, it can also restrict the pipe heating component 100 from rotating around the pipe.
[0055] In some embodiments, such as Figure 5 and Figure 6 As shown, along the radial direction of the pipe, one end face of the pipe heating assembly 100 can be configured as a concave surface, and the other end face can be configured as a convex surface. In such an embodiment, multiple pre-connected pipe heating assemblies 100 can be spliced together to adapt to the heating requirements of pipes of different lengths, while also improving the heat dissipation of the spliced pipe heating assembly 100.
[0056] In some embodiments, Figure 10 This is a schematic diagram of the mating structure of the detection element and the insulating element according to an embodiment of this application. Figure 11 This is a partial structural schematic diagram of the detection component according to an embodiment of this application. Figure 12 This is a schematic diagram of another part of the structure of the detection component according to an embodiment of this application, such as... Figures 10 to 12 As shown, the detection assembly 300 may include a plurality of detection elements 310 and a plurality of insulating elements 320. The plurality of insulating elements 320 are spaced apart from the detection elements 310 and configured to insulate adjacent detection elements 310 from each other. The portion of the detection element 310 not covered by the insulating elements 320 can contact the leaked liquid medium in the pipeline to detect the leaked liquid medium in the pipeline.
[0057] In some embodiments, such as Figure 3 As shown, a detection receiving groove 1123 is also formed on the heating fixing part 112. The extension direction of the detection receiving groove 1123 can be determined according to the actual pipeline arrangement direction to adapt to the leakage detection requirements of pipelines arranged in different directions. For example, if the actual pipeline is a horizontal pipeline, the detection receiving groove 1123 can be set parallel to the axial direction of the pipeline; if the actual pipeline is a vertical pipeline, the detection receiving groove 1123 can be set in a spiral shape, spirally wound on the heating fixing part 112. Multiple detection elements 310 and multiple insulating elements 320 can be disposed in the detection receiving groove 1123. In such an embodiment, as Figure 11 As shown, the detection assembly 300 may also include a detection fixing member 330 for fixing multiple detection members 310 and multiple insulating members 320 to the detection receiving groove 1123, so that the detection members 310 can be stably set in the detection receiving groove 1123 and the detection effect of the detection members 310 can be guaranteed.
[0058] In some embodiments, interference may exist between the detection receiving tank 1123 and the heating receiving tank 1120, therefore, as Figure 3 and Figure 10 As shown, the insulating member 320 can also form a mating groove 321, which is used to accommodate the heating part 111.
[0059] In some embodiments, such as Figure 12 As shown, the detection element 310 extends to the insulation element 120 and is connected to the housing 130. The insulation element 320 is also disposed in the insulation element 120 and covers the portion of the detection element 310 to avoid false alarms due to short circuit of the detection element 310.
[0060] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.
