Description

Technical Field

[0001] This utility model belongs to the field of pipeline technology, specifically relating to an electric heat tracing and insulation structure for pipelines. Background Technology

[0002] Electric heating tape is mainly used for pipeline insulation and antifreeze. It converts electrical energy into heat energy and automatically adjusts the output power to maintain the pipeline temperature and prevent the medium from solidifying or freezing. Electric heating tape is composed of conductive polymer, two parallel metal wires and an insulating sheath. It can automatically adjust the output power according to the temperature change of the heated system and can be cut to any length or extended within a certain range.

[0003] For example, in the Chinese utility model with announcement number CN220320643U, entitled "An Electric Heat Tracing and Insulation Structure for Defrosting Water Pipelines", although the electric heat tracing cable is pre-installed in the corrugated groove formed by the first half-pipe and the second half-pipe, and the electric heat tracing cable is set along the shape of the corrugated groove to facilitate the installation of the electric heat tracing cable, the electric heat tracing cable will cause heat loss during use, cannot heat the pipeline better, and will increase energy consumption. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed electric heat tracing and insulation structure for pipelines in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An electric heat tracing and insulation structure for pipelines includes a pipeline, a heating structure spirally arranged on the outer side of the pipeline, a plurality of insulation layers attached to the outer side of the heating structure, a support plate fixedly connected to the upper side of the pipeline, and a fixing structure pressed against the outer side of the plurality of insulation layers on one side of the support plate.

[0007] As a further optimization of this utility model, the fixing structure includes a slide rod fixedly connected to one side of the support plate, a plurality of sliders slidably connected to the outside of the slide rod, a first clamping plate fixedly connected to the bottom of the sliders, a second clamping plate rotatably connected to one side of the first clamping plate, and bolts fixedly connected to the other side of both the first clamping plate and the second clamping plate.

[0008] As a further optimization of this utility model, the heating structure includes a protective sleeve spirally arranged on the outside of the pipe, a shielding layer fixedly connected inside the protective sleeve, and several heat insulation layers arranged on the outside of the protective sleeve.

[0009] As a further optimization of this utility model, a flame-retardant layer is fixedly connected inside the shielding layer.

[0010] As a further optimization of this utility model, two insulating layers are fixedly connected inside the flame-retardant layer, and a heating cable conductor is fixedly connected inside each of the two insulating layers.

[0011] As a further optimization of this utility model, a grounding wire located on the side of the insulating layer is fixedly connected inside the flame-retardant layer.

[0012] The beneficial effects of this utility model are as follows: This utility model can position multiple insulation layers by the cooperation of the first clamping plate and the second clamping plate, and fix the positions of the first clamping plate and the second clamping plate by bolts. If one of the insulation layers is damaged, it is easy to replace it.

Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1 , Figure 2 and Figure 3As shown, an electric heat tracing and insulation structure for pipelines includes a pipeline 1 for transporting water, liquid raw materials, and other materials for convenient subsequent use. A protective sleeve 201 is spirally installed on the outer side of the pipeline 1 to protect internal components from external environmental interference and extend their service life. A shielding layer 202 is fixedly connected inside the protective sleeve 201 to limit the electromagnetic field generated during operation, preventing interference with surrounding electronic equipment. A flame-retardant layer 203 is fixedly connected inside the shielding layer 202. 3. To prevent external fire sources from igniting the electric heating cable and reduce the risk of fire, two insulating layers 204 are fixedly connected inside the flame-retardant layer 203. The insulating layers 204 prevent leakage and electric shock accidents. Heating cable conductors 205 are fixedly connected inside both insulating layers 204. The heating cable conductors 205 are generally made of highly conductive materials such as copper and nickel-chromium alloys, which are responsible for converting electrical energy into heat energy. A grounding wire 206 located on the side of the insulating layer 204 is fixedly connected inside the flame-retardant layer 203. When the insulating layer 204 is damaged, the leakage current is conducted to the ground through the grounding wire 206, preventing personnel from touching live parts and causing electric shock accidents.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, several insulation layers 5 are arranged on the outside of the protective sleeve 201. In this embodiment, there are three insulation layers 5, but the specific number can be changed according to the actual situation. The insulation layers 5 reduce heat loss, reduce the power requirement of the heating cable conductor 205, and reduce energy consumption. A support plate 3 is fixedly connected to the upper side of the pipe 1, and a sliding rod 401 is fixedly connected to one side of the support plate 3. Several sliders 402 are slidably connected to the outside of the sliding rod 401. A first clamping plate 403 is fixedly connected to the bottom of the sliders 402. In this embodiment, the number of sliders 402 is set to three, but the specific number can be changed according to the actual situation. 402 moves on the slide bar 401, causing the first clamping plate 403 to change position, which facilitates subsequent movement to the connection point of the insulation layer 5, seals the connection point, and fixes the position of the insulation layer 5 to prevent the insulation layer 5 from shifting during operation. A second clamping plate 404 is rotatably connected to one side of the first clamping plate 403. Bolts 405 are fixedly connected to both the first clamping plate 403 and the second clamping plate 404 on one side, and the positions of the first clamping plate 403 and the second clamping plate 404 are fixed by the bolts 405. If a part of the insulation layer 5 is damaged, the insulation layer 5 can be easily replaced by rotating the second clamping plate 404.

[0022] It should be noted that, in the case of this electric heat tracing and insulation structure for pipelines, the operator spirally winds the heating structure 2 around the outside of the pipeline 1. Then, an external power source (not shown in the figure) is connected to one end of the heating structure 2, and the heating structure 2 is heated through the heating cable conductor 205 inside the heating structure 2. The insulation layer 5 is wrapped around the outside of the heating structure 2, and then the insulation layer 5 is clamped by the first clamp 403 and the second clamp 404. Finally, the first clamp 403 and the second clamp 404 are fixed by bolts 405, thereby fixing the positions of the first clamp 403, the second clamp 404 and the insulation layer 5. The insulation layer 5 provides secondary insulation, allowing the heating structure 2 to supply heat to the pipeline 1 more centrally and reducing energy consumption.

[0023] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
