Description

Technical Field

[0001] This utility model relates to an aerogel encapsulation, and more particularly to an innovative structural form of an aerogel encapsulation and an electric heating insulation device for pipelines. Background Technology

[0002] In practical terms of manufacturing, some processes require the extension of pipelines to transport high-temperature fluids, and it is essential to ensure that the temperature of the fluids is maintained within a certain range during the transport process.

[0003] Therefore, related industries usually wrap the outside of the pipeline with heat insulation materials to achieve the effect of heat preservation.

[0004] Among the insulation materials currently being tested in the industry, aerogel is considered to be the most effective. Aerogel is the only known material with a density higher than that of all-carbon aerogel. It is made by replacing liquid in the gel with gas. Aerogel is an excellent thermal insulator, and it can almost completely block heat transfer caused by the three modes of heat transfer: conduction, convection, and radiation.

[0005] When aerogel is used as a pipe covering material, due to its tendency to break and pulverize, the industry typically needs to further encapsulate it in a sealed bag to prevent direct exposure and increased breakage risk. While the industry currently uses sealed bags to encapsulate the aerogel, with the bag's perimeter sealed by sewing or heat pressing, practical experience has revealed some problems with this conventional structure. For example, due to the poor sealing effect of conventional sealed bags, when the internal aerogel faces significant deformation or pressure, the fragmented dust can still leak out from the weaker parts of the seal, causing air and environmental pollution. This is a crucial technical issue that the industry needs to continue to explore and overcome. Utility Model Content

[0006] The main purpose of this utility model is to provide an aerogel encapsulation and its pipeline electric heating insulation device. The technical problem it aims to solve is to innovate and break through the goal of developing a more ideal and practical aerogel encapsulation structure.

[0007] Based on the aforementioned objectives, the purpose of this utility model is achieved as follows.

[0008] An aerogel encapsulation and pipeline electric heating insulation device is disclosed. The aerogel encapsulation includes: an aerogel and a sealing package covering the outside of the aerogel. The sealing package defines a thickness, a covering side, a back side, and an internal space, so that the aerogel is placed in the internal space. The sealing package has a plurality of heat-pressed edges, and each heat-pressed edge has a protruding length, such that the protruding length is greater than twice the thickness, so that each heat-pressed edge can be folded back and abut against the back side, and the internal space is in a vacuum state.

[0009] Another major objective of this utility model is to provide an electric heating insulation device for pipelines, which is specifically designed to cover the exterior of existing insulated conveying pipelines. The electric heating insulation device for pipelines includes an inner surface layer, an outer surface layer, and a hollow interlayer formed between the inner surface layer and the outer surface layer. The inner surface layer is used to abut against the insulated conveying pipeline, and an electric heating element and the aerogel encapsulation are sequentially housed in the hollow interlayer from the inside to the outside.

[0010] The outstanding and beneficial technical effects of this utility model compared to the prior art are as follows.

[0011] This invention provides users with an innovative aerogel sealing and pipeline electric heating insulation device. It mainly utilizes the form and technical features of each hot-pressed edge forming a protrusion length greater than twice the thickness, allowing each hot-pressed edge to fold back and abut against the back side, and the internal space to be in a vacuum state. These features effectively improve the tightness, stability and pressure resistance of the aerogel sealing, and effectively prevent the aerogel from leaking and contaminating during use. It has practical progress and better industrial utilization benefits.

[0012] Another objective of this utility model is to further include a folded edge in the sealing package, wherein the far side and two adjacent sides of the folded edge form another technical feature of the heat-pressed edge, thereby achieving the advantages and practical progress of adding a side with better airtightness to the sealing package and relatively reducing one heat-pressing process in the manufacturing process.

[0013] Another objective of this utility model is to define the long side and short side of the sealing package in a rectangular outline, so that the protrusion length of each hot-pressed edge is greater than twice the thickness, and the protrusion length is greater than half the length of the short side. This technical feature allows the hot-pressed edge to be folded back against a sufficient area on the back side, thereby achieving the advantages and practical progress of better airtightness.

[0022] Please see Figures 1 to 7 The diagram shows a preferred embodiment of the aerogel encapsulation and its pipeline electric heating insulation device of this utility model. However, these embodiments are for illustrative purposes only and are not limited to this structure in patent applications.

[0023] The aerogel encapsulation P includes an aerogel 10 and a sealing package 20 covering the outside of the aerogel 10. The sealing package 20 defines a thickness 21, a covering side 22, a back side 23, and an internal space 24, so that the aerogel 10 is placed in the internal space 24. The sealing package 20 has a plurality of hot-pressed edges 25, and each hot-pressed edge 25 has a protruding length 26, such that the protruding length 26 is greater than twice the thickness 21, so that each hot-pressed edge 25 can be folded back and abut against the back side 23, and the internal space 24 is in a vacuum state.

[0024] like Figure 6 As shown, in this example, the sealing package 20 further includes a folded edge 27, and the side furthest from the folded edge 27 and the two adjacent sides form the heat-pressed edge 25. The purpose of the folded edge 27 shown in this example is mainly to add a side with better airtightness to the sealing package 20 (note: because it has no seam or pressing seam), and in terms of process, it can relatively reduce the heat-pressing process of the heat-pressed edge 25.

[0025] like Figure 6As shown, in this example, the sealing package 20 is rectangular in shape and is defined by a long side 28 and a short side 29, such that the protrusion length 26 of each heat-pressed edge 25 is greater than twice the thickness 21, and the protrusion length 26 is greater than half the length of the short side 29. The advantage of the configuration shown in this example is that, by having a protrusion length 26 greater than half the length of the short side 29, the heat-pressed edge 25 can be folded back against a sufficient area of ​​the back side 23, thereby achieving a better airtight effect.

[0026] The sealing package 20 is made of one of the following materials: polytetrafluoroethylene film, polyimide film, polyethylene film, or polypropylene film. These materials generally possess sealing properties, high lubricity and non-stickiness, electrical insulation, good aging resistance, and excellent temperature resistance (capable of long-term operation at temperatures ranging from +250℃ to -180℃). Polytetrafluoroethylene is non-toxic to humans.

[0027] like Figures 1 to 3 As shown, this utility model further provides an electric heating insulation device 30 for pipelines, which is specifically designed to cover the outside of an existing insulated conveying pipeline 40. The electric heating insulation device 30 for pipelines includes an inner surface layer 31, an outer surface layer 32, and a hollow interlayer 33 formed between the inner surface layer 31 and the outer surface layer 32. The inner surface layer 31 is used to abut against the insulated conveying pipeline 40. An electric heating element 50 and the aforementioned aerogel encapsulation P are sequentially arranged from the inside to the outside in the hollow interlayer 33 (Note: its structure will not be described again).

[0028] like Figure 3 As shown, in this example, the heat-pressed edges 25 of the sealing package 20 of the aerogel seal P are folded back against the back side 23 and located on the side away from the electric heating element 50.

[0029] Furthermore, the aerogel encapsulation P in the hollow interlayer 33 is a single-set configuration (such as...). Figure 3 (as shown); or, the aerogel encapsulation P in the hollow interlayer 33 is a complex array arranged in parallel (e.g.) Figure 8 (As shown).

[0030] Based on the above-described structural composition and technical features, the specific molding steps of the aerogel encapsulation P disclosed in this utility model are as follows: Figures 4 to 7 As shown, the sealing package 20 can be placed flat on a heating platform 60, then the aerogel 10 is placed on the sealing package 20, and then the sealing package 20 is folded in half to form a folded edge 27 (as shown). Figure 4 As shown), and then each hot-pressed edge 25 is formed in sequence (as shown). Figure 5 As shown), before the final hot-pressing edge 25 pressing process is completed, a vacuuming process is required for the internal space 24 through a vacuum conduit 70 (as shown). Figure 5 and Figure 7(As shown); after all the hot-pressed edges 25 are completed, fold each hot-pressed edge 25 back and abut it against the back side 23 (as shown). Figure 6 As shown in the figure, the aerogel encapsulation P is now complete. The aerogel encapsulation P disclosed in this utility model mainly improves the tightness, stability and pressure resistance of the aerogel encapsulation P by forming protrusions 26 of each hot-pressed edge 25 that are more than twice the thickness 21, causing each hot-pressed edge 25 to be folded back and abut against the back side 23, and the internal space 24 to be in a vacuum state. Even when pressure is generated inside the aerogel encapsulation P, because each hot-pressed edge 25 is folded back and abuts against the back side 23, the pressure can be borne by the thickness 21 of the sealing package 20 of the aerogel encapsulation P, so it is not easy for the hot-pressed edge 25 to generate destructive tension, thereby effectively preventing the aerogel 10 from leaking and contaminating during use.
