Description

Technical Field

[0001] This invention belongs to the field of liquefied gas storage technology, and relates to an insulating module structure and its storage container. Background Technology

[0002] Storage containers are used to store liquefied gases (such as liquefied petroleum gas and liquefied natural gas). Their primary task is to ensure stable temperature and pressure during storage to guarantee the safe storage of liquefied gases. To prevent the gas in the container from evaporating due to low temperatures, insulation modules are typically used to reduce heat exchange and maintain the stability of the liquefied gas. However, existing insulation modules still have shortcomings in terms of improving structural strength, construction safety, and space saving. For example, common membrane enclosure systems usually consist of several layers of insulation material, but these systems may have certain limitations in terms of structural strength, construction safety, and ease of installation.

[0003] Currently, common insulation modules employ a plywood-filled polyurethane design. While this design effectively provides insulation, the polyurethane layer structure is prone to damage under high-intensity impacts, lacking effective support and posing certain safety hazards. Furthermore, existing structural designs fail to fully utilize the advantages of truss structures, thus failing to effectively improve the strength and stability of the insulation modules.

[0004] To address the aforementioned issues, there is an urgent need for an improved design that can enhance the strength and safety of insulation modules and simplify the construction process. Summary of the Invention

[0005] In view of this, and to address the problem of insufficient effective support for polyurethane structures in existing membrane enclosure systems, making them susceptible to damage from high-intensity impacts, this invention aims to propose an insulation module structure and its storage container. This insulation module structure mainly consists of a shielding assembly, insulation modules, and anchoring components. The design of the shielding assembly has been further optimized. The shielding assembly and insulation modules are fixedly connected via anchoring components, increasing the overall strength of the membrane enclosure system. Simultaneously, the improved anchoring components effectively enhance the insulation performance, structural strength, and construction safety of the storage container. The grid-like structure design improves the stability of the resulting membrane enclosure system and achieves a lightweight design.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] To achieve the above objectives, the present invention provides a thermal insulation module structure, which includes a shielding group, a thermal insulation module, and an anchoring component, wherein the shielding group and the thermal insulation module are fixedly connected by the anchoring component.

[0008] The shielding assembly includes a main shielding layer, a main plywood, and a secondary shielding layer, with the main plywood disposed between the main shielding layer and the secondary shielding layer;

[0009] The insulation module includes a first plywood, a second plywood, and a truss structure disposed between the first plywood and the second plywood. The truss structure encloses and divides to form multiple insulation filling areas, and the insulation filling areas are filled with reinforced polyurethane foam.

[0010] The first plywood is disposed on the side of the insulation module near the shielding group, and the shielding group, the first plywood and the truss structure are fixedly connected by the anchoring assembly.

[0011] In some embodiments, the anchoring assembly includes a blind hole anchor tube, a secondary anchor plate, an anchor bolt, and a main anchor plate. The truss structure has an anchor hole on the side near the first plywood, the anchor hole having a convex cross-section. The blind hole anchor tube is sleeved and installed in the anchor hole. The secondary anchor plate is embedded and installed in the side of the first plywood near the secondary shielding layer. The main anchor plate is embedded and installed in the side of the main plywood near the main shielding layer. The blind hole anchor tube passes through the first plywood. The main plywood has an anchor assembly hole at the location corresponding to the anchor hole, the anchor assembly hole having an inverted convex cross-section. The anchor bolt is assembled in the anchor assembly hole and passes through the main plywood, the secondary shielding layer, and the first plywood, and is threadedly connected to the blind hole anchor tube.

[0012] In some embodiments, the truss structure is a grid-like reinforced frame formed by welding steel structures together, and an insulation board is embedded and fixed on the inner sidewall of the truss structure; the main shielding layer and the secondary shielding layer are provided with corrugated areas and planar areas, the corrugated areas are staggered around the planar areas, the main plywood is located in the planar areas, the main plywood is distributed in a matrix array in the planar areas, the corrugated areas limit, separate and fix the arrayed main plywood, and the main shielding layer and the secondary shielding layer of the shielding group are metal films formed by bending technology.

[0013] In some embodiments, the four corners of the main plywood are provided with fitting grooves that fit against the inner walls of the main shielding layer and the secondary shielding layer. After being bent and shaped, the main plywood is fitted and fixed to the main shielding layer and the secondary shielding layer. The side of the main plywood fits against the inner wall of the wavy partition area of ​​the main shielding layer and the secondary shielding layer. The anchoring assembly holes are located directly above the transversely and longitudinally distributed structural beams of the grid-like reinforcing frame, and are used to fix the shielding assembly to the structural beams of the truss structure by the anchoring assembly.

[0014] In some embodiments, a stop block is provided on the outer wall of the blind hole anchor pipe to limit it to the anchor hole, and a secondary anchor plate is sleeved on the blind hole anchor pipe and embedded in the upper surface of the first plywood.

[0015] In some embodiments, the truss structure of the insulation module is divided into a grid-like reinforcing frame by transverse and longitudinal structural beams. The transverse and longitudinal structural beams are fixedly connected to the shielding group and the first plywood by four sets of anchoring components. The main shielding layer and the secondary shielding layer of the shielding group are formed by bending and shaping to limit the array of main plywood to form the shielding group.

[0016] In some embodiments, the truss structure of the insulation module is a rectangular frame with transverse and longitudinal structural beams connected by columns, and the upper and lower rectangular frames, structural beams and columns are connected by diagonally welded reinforcing columns. The reinforcing columns divide the truss structure into several triangular areas, and the triangular areas are filled with insulation panels.

[0017] In some embodiments, the columns on the inner side of each triangular area of ​​the mesh-reinforced frame are provided with inner inclined surfaces, which are used to limit and block the insulation panels installed from the inside of the truss structure to the triangular area. The insulation panels are provided with stop inclined surfaces that engage with the inner inclined surfaces.

[0018] In some embodiments, the insulation board is filled within the truss structure, forming an insulation cavity of the insulation module with a first plywood located above the truss structure and a second plywood located below the truss structure in the insulation filling area. The first plywood is disposed between the truss structure and the shielding assembly, and the second plywood is disposed between the truss structure and the resin putty. The insulation cavity is filled with reinforced polyurethane foam.

[0019] The present invention also provides a storage container having the heat insulation module structure described in any of the above embodiments, wherein the heat insulation module structure is fixedly disposed on the inner wall of the storage container.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In the design of the shielding assembly, this invention uses anchoring components to fix the truss structure, significantly improving the overall structural strength. In particular, the use of the metal membrane and truss structure in the membrane enclosure system gives the entire structure better load-bearing capacity, effectively resisting the effects of external pressure and temperature changes, and extending the service life of the storage container.

[0022] 2. By incorporating triangular zones on the sides of the truss structure and filling these zones with insulation panels, the strength and stability of the structure are further enhanced. In particular, the column design within the triangular zones, combined with the inner slope, effectively limits the displacement of the insulation panels, ensuring long-term stability after filling with reinforced polyurethane foam. The truss structure of this invention is optimized, employing various structural units such as triangular zones, V-shaped reinforcing columns, and diagonally tensioned columns. These units can rationally distribute and bear external loads, avoiding stress concentration and improving the overall structural stability and reliability. The optimized structural design makes the insulation modules more robust and durable. Due to its enhanced strength and stability, the maintenance requirements of the storage containers are significantly reduced, decreasing the frequency of periodic inspections and component replacements, thereby lowering operating and maintenance costs.

[0023] 3. The storage container of this invention, by incorporating an insulating module structure, effectively avoids the loss of cold energy during liquefied gas storage, thereby reducing liquefied gas vaporization and improving energy efficiency. Higher thermal insulation performance means less energy consumption and helps reduce the environmental impact of excessive energy consumption. Through the structural design of the insulating module structure, especially the connection method between the truss structure and the shielding assembly, this invention not only improves the structural stability of the storage container but also simplifies the production and construction process, increasing work efficiency. The grid structure design enhances the stability of the resulting membrane enclosure system and achieves lightweight design. The truss structure and membrane enclosure system of this invention can withstand extreme environmental conditions, are suitable for liquefied gas storage needs in different regions, have stronger environmental adaptability, and ensure the reliability and stability of the container in various environments.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1 to 9As shown, an embodiment of the present invention provides a thermal insulation module structure, which includes a shielding group 1, a thermal insulation module 3, and an anchoring component 16. The shielding group 1 and the thermal insulation module 3 are fixedly connected by the anchoring component 16. The shielding group 1 includes a main shielding layer 11, a main plywood 12, and a secondary shielding layer 13. The main plywood 12 is disposed between the main shielding layer 11 and the secondary shielding layer 13. The thermal insulation module 3 includes a first plywood 2, a second plywood 4, and a truss structure 31 disposed between the first plywood 2 and the second plywood 4. The truss structure 31 encloses and divides to form a plurality of thermal insulation filling areas 33, which are filled with reinforced polyurethane foam. The first plywood 2 is disposed between the shielding group 1 and the thermal insulation module 3, and the shielding group 1 and the first plywood 2 are fixedly connected to the truss structure 31 by the anchoring component 16.

[0038] See Figure 5 and Figure 6 In this embodiment, the anchoring assembly 16 includes a blind hole anchoring pipe 161, a secondary anchoring plate 162, an anchoring bolt 163, and a main anchoring plate 164. The truss structure 31 has an anchoring hole 312 on the side near the first plywood 2. The anchoring hole 312 has a convex cross-section. The blind hole anchoring pipe 161 is sleeved and installed in the anchoring hole 312. The secondary anchoring plate 162 is embedded and installed on the side of the first plywood 2 near the secondary shielding layer. The main anchoring plate 164 is embedded and installed on the side of the main plywood 12 near the main shielding layer. The blind hole anchoring pipe 161 passes through the first plywood 2. The main plywood 12 has an anchoring assembly hole 17 at the position corresponding to the anchoring hole 312. The anchoring assembly hole 17 has an inverted convex cross-section. The anchoring bolt 163 is assembled in the anchoring assembly hole 17 and passes through the main plywood 12, the secondary shielding layer 13, and the first plywood 2 and is threadedly connected to the blind hole anchoring pipe 161.

[0039] See Figure 6 In this embodiment, a threaded blind hole anchor pipe 161 is installed in the anchor hole 312 on the structural beam 311. A stop block is provided on the outer wall of the blind hole anchor pipe 161 to limit its position within the anchor hole 312. A secondary anchor plate 162 is sleeved on the blind hole anchor pipe 161 and embedded in the upper surface of the first plywood 2. Anchor bolts 163 pass through the main plywood 12 and the secondary shielding layer 13 in sequence. Anchor assembly hole 17 is threadedly connected to the blind hole anchor pipe 161. The main anchor plate 164 is installed above the anchor assembly hole 17 of the main plywood 12 and is fixedly connected to the main shielding layer 11. It can fix the stress of the main shielding layer 11 shrinking at low temperature and play the role of anchoring at the fixed point. The shielding group 1, the first plywood 2 and the truss structure 31 of the insulation module 3 are connected and fixed through the anchor assembly 16.

[0040] See Figure 5In this embodiment, the truss structure 31 can be a grid-like reinforced frame formed by welding steel structures together, and an insulation board 32 is embedded and fixed on the inner wall of the truss structure 31. The interior of the truss structure 31 is divided by the insulation board 32 to form independent insulation filling areas 33, and reinforced polyurethane foam is filled in the insulation filling areas 33; the bottom of the second plywood 4 is provided with resin putty 5 for fixing the insulation module structure to the inner wall of the storage container, and the resin putty 5 and the installation base of the inner wall of the storage container constitute an anchoring component 16.

[0041] See Figure 5 In this embodiment, the main shielding layer 11 and the secondary shielding layer 13 are provided with corrugated regions 15 and planar regions 151. The corrugated regions 15 are staggered around the planar regions 151. The main plywood is located in the planar regions 151. The main plywood 12 is distributed in a matrix array in the planar regions 151. The corrugated regions 15 limit, separate and fix the arrayed main plywood 12. The main shielding layer 11 and the secondary shielding layer 13 of the shielding group 1 are metal films formed by bending technology.

[0042] In the design of the shielding group 1, the truss structure 31 is fixedly connected by the anchoring component 16, which significantly improves the overall structural strength. In particular, the metal membrane and truss structure 31 in the membrane enclosure system give the entire structure better load-bearing capacity, effectively resisting the effects of external pressure and temperature changes, and extending the service life of the storage container.

[0043] See Figure 8 The main plywood 12 has four corners with fitting grooves 121 that fit with the inner walls of the main shielding layer 11 and the secondary shielding layer 13. After being bent and formed, it fits and is fixed with the main shielding layer 11 and the secondary shielding layer 13. The side of the main plywood 12 fits with the inner wall of the wavy partition area of ​​the main shielding layer 11 and the secondary shielding layer 13.

[0044] In this embodiment, in shielding group 1, one end of stud 14 is welded to the upper surface of secondary shielding layer 13 and connected and fixed to the nut inside the main plywood 12, thereby connecting and fixing the main plywood 12 and secondary shielding layer 13. The main plywood 12 is disposed on the main shielding layer 11 and secondary shielding layer 13 to form shielding group 1.

[0045] In this embodiment, anchoring assembly holes 17 are also provided on the main plywood 12 and the secondary shielding layer 13. The anchoring assembly holes 17 are located directly above the structural beams 311 distributed laterally and longitudinally in the grid-like reinforcing frame. The anchoring assembly holes 17 are rectangular grooves used to anchor the assembly 16 to fix the shielding group 1 to the structural beams 311 of the truss structure 31.

[0046] The anchoring assembly hole 17 can be any shape of assembly groove, such as a rectangular groove or a circular groove. In this embodiment, a rectangular groove is preferred. During installation, the two anchoring assembly holes 17 set in the same direction along the structural beam 311 can be fixed first by the anchoring component 16. Then, the two rectangular assembly grooves opened at 45 degrees relative to the distribution direction of the lower structural beam 311 can be fixed again by the anchoring component 16. The shielding group 1 is fixed at the four anchoring assembly holes 17 by four sets of anchoring components 16. The shielding group 1 is fixed to the structural beam 311 of the truss structure 31 by the anchoring components 16.

[0047] In this embodiment, the shielding group 1 and the insulation module 3 can also be fixedly connected by an adjustable spring damping connection structure. This adjustable spring damping connection structure is connected by studs on the mounting base of the inner wall of the storage container, the shielding group 1, the insulation module 3, and the inner wall of the storage container. The studs pass through the vertically set mounting holes from one side of the shielding group 1 and are connected to the screw holes set on the mounting base of the inner wall of the storage container. A spring and a limiting plate located outside the spring are fitted into the mounting holes of the insulation module 3. A damping medium is set in the mounting holes outside the limiting plate. After the studs are installed, insulating gap glass wool is set in the mounting holes in the shielding group 1 for rigid insulation. After being fixedly connected by the adjustable spring damping connection structure, each independent module of the insulation module structure can be allowed to deform freely while being effectively limited.

[0048] In this embodiment, the truss structure 31 of the insulation module 3 is divided into a grid-like reinforced frame by structural beams 311 distributed laterally and longitudinally. The structural beams 311 distributed laterally and longitudinally are fixedly connected to the shielding group 1 and the first plywood 2 by four sets of anchoring components 16. The main shielding layer 11 and the secondary shielding layer 13 of the shielding group 1 are bent and shaped to limit the nine sets of main plywood 12 distributed in an array to form the shielding group 1.

[0049] In this embodiment, after the shielding group 1 is fixedly connected to the truss structure 31 of the insulation module 3 through the anchoring component 16, the first plywood 2 is clamped and fixed between the shielding group 1 and the truss structure 31.

[0050] See Figure 7 In this embodiment, the truss structure 31 of the insulation module 3 is a rectangular frame 314 with transverse and longitudinal structural beams 311 connected by columns 313. The upper and lower rectangular frames 314, structural beams 311, and columns 313 are also connected by obliquely welded reinforcing columns 315. The reinforcing columns 315 divide the truss structure 31 into several triangular areas 316, each filled with an insulation plate 32. Each triangular area 316 of the grid-like reinforcing frame has an inner inclined surface 317 on its inner column. The inner inclined surface 317 is used to limit and block the insulation plate 32 installed from the inside of the truss structure 31 to the triangular area 316. (See reference...) Figure 9 The insulation board 32 is provided with a stop slope 321 that engages with the inner slope 317.

[0051] By providing a triangular region 316 on the side of the truss structure 31 and filling this region with an insulation board 32, the strength and stability of the structure are further increased. In particular, the column design of the triangular region 316, combined with the inner inclined surface 317, effectively restricts the displacement of the insulation board 32, ensuring long-term stability after filling with reinforced polyurethane foam 34. The truss structure 31 of the present invention has been optimized and adopts a variety of structural units such as the triangular region 316, V-shaped reinforcing columns 315, and diagonally tensioned columns. These units can rationally distribute and bear external loads, avoid stress concentration problems, and improve the stability and reliability of the overall structure. Through optimized structural design, the insulation module 3 is made more robust and durable. Due to its enhanced strength and stability, the maintenance requirements of the storage container are significantly reduced, the frequency of periodic inspections and component replacements is reduced, thereby reducing operating and maintenance costs.

[0052] In this embodiment, the insulation board 32 is filled inside the truss structure 31, and together with the first plywood 2 located above the truss structure 31 and the second plywood 4 located below the truss structure 31, they form the insulation cavity of the insulation module 3 in the insulation filling area 33. The first plywood 2 is disposed between the truss structure 31 and the shielding group 1, and the second plywood 4 is disposed between the truss structure 31 and the resin putty 5. The insulation cavity is filled with reinforced polyurethane foam 34, which can provide further thermal insulation performance.

[0053] The bottom of the second plywood 4 is provided with several adhesive strips arranged in a strip shape to form resin putty 5. Main adhesive strips 51 are distributed below the rectangular frame 314 of the truss structure 31 and the structural beam 311. Several secondary adhesive strips 52 are distributed between the main adhesive strips 51. The resin putty 5 is used to fix the shielding assembly 1 and the insulation module 3 to the mounting base on the inner wall of the storage container. In this embodiment, the resin putty 5 at the bottom of the second plywood 4 can be an adhesive strip, a bonding surface, or any other shape.

[0054] Embodiments of the present invention also provide a storage container with an insulation module structure, which is fixedly connected to the inner wall of the storage container. See [link to related documentation]. Figure 10 As shown, the shielding group 1 and the insulation module 3 of the insulation module structure are fixedly installed on the inner side of the outer tank wall 7 and the bottom 72 of the outer tank through the anchoring component 16. The top 71 of the outer tank is provided with a suspended ceiling insulation structure 73. The pump structure 6 installed in the storage container passes through the suspended ceiling insulation structure 73 and the top 71 of the outer tank in sequence and is connected to the outside.

[0055] The storage container of the present invention, equipped with an insulating module structure, effectively reduces heat loss during liquefied gas storage, thereby improving energy efficiency. Higher thermal insulation performance means less energy consumption and helps reduce the environmental impact of excessive energy consumption. Through the structural design of the insulating module structure, especially the connection between the truss structure 31 and the shielding group 1, the present invention not only improves the structural stability of the storage container but also simplifies the production and construction process, increasing work efficiency. The grid structure design enhances the stability of the resulting membrane enclosure system and achieves a lightweight design. The truss structure 31 and membrane enclosure system of the present invention can withstand extreme environmental conditions, are suitable for liquefied gas storage needs in different regions, have stronger environmental adaptability, and ensure the reliability and stability of the container in various environments.
