[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0032] Embodiment 1:
[0033] The utility model provides a hard heat-insulating pipe shell, such as Figures 1 to 3 As shown, the rigid heat-insulating pipe shell comprises a pipe shell body 1, and the pipe shell body 1 is configured as a ceramic fiber pipe shell.
[0034] A reinforcement structure is pre-buried in the ceramic fiber tube shell, and the reinforcement structure is configured as a mesh structure 2 .
[0035] When in use, the rigid heat-insulating pipe shell is wrapped onto the steam pipe.
[0036] In the above process, the shell body 1 adopts a ceramic fiber shell, which has a good thermal insulation effect and can meet the thermal insulation requirements of the overhead steam pipeline. The shell body 1 has a mesh structure 2, which can effectively improve the structural strength and toughness of the overall shell, greatly improve the product quality, and effectively avoid damage to the shell due to bumps or bumps during transportation or installation.
[0037] The production process of the rigid thermal insulation pipe shell is as follows:
[0038] (1) slurrying, placing the ceramic fiber waste in a slurrying tank, adding a binder, and fully stirring to obtain a slurry;
[0039] (2) Grouting: The slurry is injected into the mold through a pipeline. Before or during the grouting, the mesh structure is placed in the slurry, and then dehydrated and dried to form a hard insulation pipe shell with the mesh structure pre-buried inside the pipe shell body.
[0040] Example 2:
[0041] Example 2 is based on Example 1:
[0042] As shown in Figure 3 , the mesh structure 2 includes a circular weft 21 and an axial warp 22.
[0043] The number of the circular wefts 21 is set to be multiple, and all the circular wefts 21 are arranged in sequence along the axis of the axial warp 22. The number of the axial warps 22 is set to be multiple, and all the axial warps 22 are arranged in sequence along the circumference of the circular weft 21; the circular weft 21 and the axial warp 22 intersect.
[0044] In this way, a columnar grid structure is formed, and the columnar grid structure is adapted to the shell body 1, which can effectively ensure the strength and toughness of the shell.
[0045] As an optional implementation manner, as shown in Figure 4 , the circular weft 21 includes a plurality of unit wefts 211 arranged uniformly along the circumference, and all the unit wefts 211 are arranged at intervals in sequence.
[0046] In this way, the mesh structure 2 forms a plurality of unit network segments distributed along the circumference.
[0047] As an optional implementation manner, the circular weft 21 is set as a first wavy line. Using a wavy circular weft can increase the coverage area of the mesh structure and further improve the strength and toughness.
[0048] As an optional implementation manner, as shown in Figure 5 , the first wavy line is set as a transverse wave, the waveform center line of the transverse wave is located in the horizontal plane, and the waveform center line is the waveform center line of the wave crest and the wave trough of one period of the wavy line, that is, the plane where the transverse wave is located is the horizontal plane.
[0049] In this implementation manner, axial warps 22 are arranged at both the wave trough position and the wave crest position of the transverse wave. In this way, a double-layer warp layer can be formed, namely an inner axial warp layer and an outer axial warp layer.
[0050] As an optional implementation manner, as shown in Figure 6 , the first wavy line is set as a longitudinal wave, and the waveform center line of the longitudinal wave is located in the vertical plane.
[0051] In this implementation manner, two adjacent axial warps 22 are respectively located at the wave trough position and the wave crest position of the longitudinal wave.
[0052] As an optional implementation manner, as shown in Figure 3 , the axial warp 22 is set as a straight line and arranged along the vertical direction.
[0053] As an alternative implementation, as Figure 7 shown, the axial warp 22 is arranged as a second wavy line, and the waveform center line of the second wavy line is located in the vertical plane.
[0054] The axial warp 22 adopting the wavy line structure can effectively increase the coverage area of the mesh structure 2 on the shell body 1, thereby further improving the overall strength and toughness of the shell.
[0055] As an alternative implementation, as Figure 8 shown, the axial warp 22 includes a plurality of unit warps 221 arranged uniformly along the axis; all the unit warps 221 are arranged at intervals in sequence.
[0056] In this way, a plurality of unit network segments distributed in the vertical direction can be formed.
[0057] As an alternative implementation, the mesh structure 2 is made of basalt, aluminosilicate or glass wool.
[0058] The basalt material, aluminosilicate material and glass wool material are all heat-resistant and heat-insulating materials. In the actual application process, the user selects the specific material of the mesh structure 2 according to the actual needs.
