Abstract
Description
Technical Field
[0001] The present invention relates to an aerogel package, and particularly to an electric heating insulation device for an aerogel package and its pipeline.
Background Art
[0002] In the practical aspects of manufacturing and processing, a certain process requires transporting a certain high-temperature fluid as the pipeline extends. And during the transportation process, it is necessary to keep the temperature of the fluid within a certain range.
[0003] For this reason, it is common in the related industry to cover the peripheral surface of the pipeline with a heat insulation material, thereby obtaining a heat insulation effect.
[0004] Currently, among the heat insulation materials used in the related industry, aerogel is the material with the best effect. Aerogel is currently a substance with a density higher only than that of all-carbon aerogel. Aerogel is produced by replacing the position of gas in a liquid gel and is an excellent heat insulation material. Aerogel can almost block heat transfer by the three heat transfer methods of heat conduction, heat convection, and heat radiation.
[0005] When aerogel is used as a material to cover pipelines, it has the weaknesses of being easily damaged and prone to dust flying. Therefore, it is necessary for related industries to package the aerogel in a sealed bag. This can avoid exposing the aerogel directly to the outside and increasing the risk of damage. Currently, well-known related industries package the aerogel with a sealed bag and form a sealed edge around the sealed bag by general sewing or heat pressing. However, in actual use experience, such a conventional structure has the following drawbacks. For example, the sealing effect of the sealed edge of the conventional sealed bag is not good. When the aerogel inside has a larger deformation or higher pressure, the pulverized dust is likely to leak out from the weaker parts of the sealed edge. As a result, there is a problem that the surrounding air and environment are polluted.
Summary of the Invention
Problems to be Solved by the Invention
[0006] The main purpose of the present invention is to provide an aerogel package having an ideal and practical structure and an electric heating and heat insulation device for its pipeline.
Means for Solving the Problems
[0007] According to the aerogel package of the present invention, it includes an aerogel and a seal package covering the outer surface of the aerogel. The seal package defines a thickness, a covering side, a back side, and an internal space. Thereby, the aerogel is placed inside the internal space. A plurality of heat-pressed edges are formed on the seal package, and a protruding length is formed on each heat-pressed edge. The protruding length is greater than twice the thickness. Each heat-pressed edge can be folded and pressed against the back side, and the internal space is in a vacuum state.
[0008] According to the electric heating and heat insulation device for a pipeline of the present invention, it covers the outer surface of an existing heat-insulated transportation pipeline, and includes a back layer, an outer layer, and a hollow jacket formed between the back layer and the outer layer. The back layer is pressed against the heat-insulated transportation pipeline, and in the hollow jacket, an electric heating sheet and an aerogel package are accommodated in sequence from the inside to the outside.
Advantages of the Invention
[0009] According to the aerogel package and the electric heating and heat insulation device for its pipeline of the present invention, the following effects are achieved. (1) Due to such a structural form and technical features, the aerogel package and the electric heating and heat insulation device for its pipeline according to the present invention mainly form a protruding length greater than twice the thickness at each thermocompression edge, fold each thermocompression edge and press it against the back side, and have forms and technical features such as the internal space being in a vacuum state. Thereby, the compactness, stability, and pressure resistance of the sealed state of the aerogel package can be effectively improved, and the problem of leakage during the use of the aerogel and contamination of the outside can be surely prevented.
[0010] (2) The seal package further includes a folding edge. Since the side far from the folding edge and two adjacent sides form thermocompression edges, the seal package has better airtight side edges, and the processing process can reduce one thermocompression step.
[0011] (3) The seal package has a rectangular contour, has a long side and a short side, and the protruding length of each thermocompression edge is greater than twice the thickness and greater than half the length of the short side. Thereby, the area where the thermocompression edge is folded and pressed against the back side is sufficient, and the airtight effect is improved.

Embodiments for Carrying out the Invention
[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0014] Figures 1 to 7 show embodiments of the aerogel package and its electric heating and heat insulation device for a pipeline according to the present invention, but these embodiments are only used for explanation, and of course, the present invention is not limited to this structure.
[0015] The aerogel package P includes an aerogel 10 and a seal package 20 that covers the outer surface of the aerogel 10. The seal package 20 is formed with a thickness 21, a covering side 22, a back side 23, and an internal space 24. The aerogel 10 is placed within the internal space 24. A plurality of thermocompression edges 25 are formed on the seal package 20, and each thermocompression edge 25 is formed with a protruding length 26. The protruding length 26 is greater than twice the thickness 21, each thermocompression edge 25 is folded back and pressed against the back side 23, and the internal space 24 is in a vacuum state.
[0016] As shown in FIG. 6, in this example, the seal package 20 further includes a folding edge 27. The side farther away from and two adjacent sides of the folding edge 27 form the thermocompression edges 25. In this example, the purpose of providing the folding edge 27 is mainly to increase a better airtight side edge for the seal package 20 (because a design without seams or compression seams is designed), and in the processing process, the process of thermocompressing the thermocompression edges 25 can be reduced by one time.
[0017] As shown in FIG. 6, in this example, the seal package 20 has a rectangular contour, defining a long side 28 and a short side 29. The protruding length 26 of each thermocompression edge 25 is greater than twice the thickness 21, and the protruding length 26 is made greater than half the length of the short side 29. In the form of this example, the advantage is mainly that due to the feature that the protruding length 26 is greater than half the length of the short side 29, the area where the thermocompression edge 25 is folded back and pressed against the back side 23 is sufficient, and thus the airtight effect is better.
[0018] The seal package 20 employs a polytetrafluoroethylene film, a polyimide film, a polyethylene film, or a polypropylene film. The above materials basically have airtightness, high lubricity and non-stickiness, electrical insulation, excellent anti-aging properties, and excellent heat resistance (operable for a long time at temperatures from +250°C to -180°C). Among them, polytetrafluoroethylene does not show a toxic reaction to the human body.
[0019] Refer to FIGS. 1 to 3. The electric heating and heat insulation device 30 for a pipeline according to the present invention covers the outer surface of an existing heat-insulated transport pipeline 40. The electric heating and heat insulation device 30 for a pipeline includes a back surface layer 31, an outer surface layer 32, and a hollow jacket 33 formed between the back surface layer 31 and the outer surface layer 32. The back surface layer 31 is for pressing against the heat-insulated transport pipeline 40. Inside the hollow jacket 33, an electric heating sheet 50 and an aerogel package P are accommodated in order from the inside to the outside. (The description of its structure is omitted.).
[0020] In this example, as shown in FIG. 3, each heat press-bonded edge 25 formed on the seal package 20 of the aerogel package P is folded back and pressed against the back side 23 and is located on the side away from the electric heating sheet 50.
[0021] Also, as shown in FIG. 3, the aerogel package P is arranged in a single-group pattern in the hollow jacket 33. Alternatively, as shown in FIG. 8, the aerogel package P is arranged with a plurality of group patterns in parallel in the hollow jacket 33.
[0022] Due to the above structure and technical features, the specific forming steps of the aerogel package P according to the present invention are as follows. As shown in FIGS. 4 to 7, the seal package 20 is placed flat on the heating platform 60, the aerogel 10 is placed on the seal package 20, and the seal package 20 is folded in half to form a folding edge 27 as shown in FIG. 4. Next, as shown in FIG. 5, each thermocompression edge 25 is formed in sequence. Before completing the step of compressing the thermocompression edge 25 on the last side, as shown in FIGS. 5 and 7, a single vacuum duct 70 is used to evacuate the internal space 24. After each thermocompression edge 25 on each side is completed, as shown in FIG. 6, each thermocompression edge 25 is folded back and pressed against the back side 23. Then, the formation of the aerogel package P is completed. The aerogel package P according to the present invention mainly has a protruding length 26 formed on each thermocompression edge 25 that is greater than twice the thickness 21. Due to forms and technical features such as each thermocompression edge 25 being folded back and pressed against the back side 23 and the internal space 24 being in a vacuum state, the sealing performance, stability, and pressure resistance of the sealed state of the aerogel package P are improved. Even if pressure is generated inside the aerogel package P, since each thermocompression edge 25 is folded back and pressed against the back side 23, the aerogel package P can withstand pressure in the thickness 21 direction of the seal package 20. Therefore, it is difficult to generate a tension that destroys the thermocompression edge 25, and the aerogel 10 can effectively prevent the problem of leaking out and contaminating the outside during use.
