Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation pipes, in particular to an aerogel thermal insulation pipe. Background Art

[0002] Aerogel is an emerging material. As a nano-scale porous solid material, it has extremely low density and excellent thermal insulation properties. Therefore, it has been used in pipeline insulation in recent years. At present, the common method of pipeline insulation is to wrap the oil pipe with aerogel material to achieve insulation.

[0003] However, during the application of this method, although the aerogel material can wrap the pipe by coating, the aerogel material is prone to damage due to its low physical strength. Therefore, the current insulation pipe is sometimes wrapped with aerogel by an outer tube, or wrapped with an anti-corrosion layer. However, both of the above structures have the problem of aging of the aerogel material as the application time increases, and the removal and replacement operation is inconvenient. In view of this, in-depth research on the above problems has led to the creation of this case. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 The present invention provides an implementation scheme: In the application process of modern thermal insulation pipes, aerogel is mostly wrapped around the outside of the aerogel. During the application process of aerogel, due to aging and corrosion problems during use, the aerogel insulation layer needs to be replaced regularly. However, the current method of replacing the aerogel insulation layer mainly uses a wrapping and bundling method to protect the inner tube 1. However, this method is very inconvenient because the connecting pieces fixing the inner tube 1 and the outer tube 2 on both sides are blocked.

[0022] According to the instruction manual Figure 1-4 It can be seen that in response to the above problems, the present application discloses an aerogel thermal insulation pipe, which specifically includes an inner pipe 1, an outer pipe 2 and a thermal insulation layer 3, wherein the inner pipe 1, the thermal insulation layer 3 and the outer pipe 2 are coaxially arranged from the inside to the outside, and the thermal insulation layer 3 is clamped between the annulus of the inner pipe 1 and the outer pipe 2, and then a quick-change assembly is provided at both ends of the inner pipe 1 and the outer pipe 2. The quick-change assembly can be used to quickly separate the inner pipe 1 and the outer pipe 2, and then the thermal insulation layer 3 outside the inner pipe 1 can be removed and replaced, thereby improving the convenience of disassembling and replacing the inner pipe 1 and the outer pipe 2 and facilitating replacement;

[0023] According to the instruction manual Figure 1-3 It can be seen that one end of the inner tube 1 is provided with an externally threaded socket 4, one end of the externally threaded socket 4 is threadedly connected to a coaxial ring sleeve 5, and a plurality of first connecting pieces 6 are arranged in a ring array on the coaxial ring sleeve 5. The plurality of first connecting pieces 6 are welded to the inner side of the outer tube 2 and are threadedly connected to the coaxial ring sleeve 5 through the externally threaded socket 4. The plurality of first connecting pieces 6 on the coaxial ring sleeve 5 are extended outward to connect to the inner wall of the outer tube 2 to connect the outer tube 2 and the coaxial ring sleeve 5. When the thermal insulation layer 3 is removed and replaced, the outer tube 2 is disassembled by rotating the coaxial ring sleeve 5;

[0024] According to the instruction manual Figure 1-4It can be seen that one end of the outer tube 2 is provided with an internally threaded sleeve 7, and a docking ring sleeve 8 is threadedly connected to the internally threaded sleeve 7. A plurality of second connecting pieces 9 arranged in a ring array are extended inwardly from the docking ring sleeve 8. The plurality of second connecting pieces 9 are fixedly connected to the inner tube 1. During the process of threaded connection of the outer tube 2 and the coaxial ring sleeve 5 for switching, the internally threaded sleeve 7 is threadedly connected to the docking ring sleeve 8. When the outer tube 2 is rotated, the docking ring sleeve 8 is fixed. Since the docking ring sleeve 8 is fixedly connected to the inner tube 1 through the second connecting piece 9, the docking ring sleeve 8 is fixedly connected to the inner tube 1. During the removal and replacement process of the coaxial ring sleeve 5, the connection between the docking ring sleeve 8 and the internally threaded sleeve 7 is also released.

[0025] The thermal insulation layer is a rectangular plate with an annular structure. Several limiting rings 10 are arranged axially inside the thermal insulation layer. The limiting rings 10 inside the thermal insulation layer play a role in limiting the thermal insulation layer.

[0026] As a preferred solution, further, a plurality of limiting grooves are provided on the inner tube 1, and the plurality of limiting grooves are grooves of annular structure.

[0027] As a preferred solution, further, both sides of the limiting ring 10 are sloped surfaces, and both sides of the limiting groove match the sloped surfaces of the limiting ring 10 to play a guiding role and facilitate installation.

[0028] As a preferred solution, further, several first connecting plates 6 and several second connecting plates 9 are rectangular structural plates of the same specifications, and the two ends of the thermal insulation layer are symmetrically contacted with several first connecting plates 6 and several second connecting plates 9, respectively, and the first connecting plates 6 and the second connecting plates 9 limit the two ends of the thermal insulation layer respectively.

[0029] As a preferred solution, further, the coaxial ring sleeve 5 matches the outer wall diameter of the inner tube 1, and the outer diameter of the docking ring sleeve 8 matches the diameter of the outer tube 2 to maintain structural consistency.

[0030] As a preferred solution, further, a pair of connecting rings 11 are provided at one end of the outer tube 2 and one end of the docking ring sleeve 8, and a pair of connecting rings 11 are provided with a plurality of pulling connecting holes to facilitate docking of adjacent thermal insulation pipes.

[0031] To sum up, it can be seen that the aerogel thermal insulation pipe uses the annulus between the inner tube 1 and the outer tube 2 as the installation space for the thermal insulation layer 3. In order to facilitate the removal and replacement of the thermal insulation layer, the inner tube 1 and the outer tube 2 are fixedly connected by coaxial ring sleeves 5 and docking ring sleeves 8 arranged in an interlaced manner at both ends. When replacing, it is only necessary to rotate the inner tube 1 and the outer tube 2 to unlock the threads, which is convenient for removing and replacing the thermal insulation layer.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
