Description

Technical Field

[0001] The present invention belongs to the technical field of liquefied gas storage and relates to a heat-insulating module structure and a storage container thereof. Background Art

[0002] Storage containers are used to store liquefied gases (such as liquefied petroleum gas and liquefied natural gas). Their primary function is to maintain stable temperature and pressure during storage to ensure safe storage of the liquefied gas. To prevent evaporation of the gas in the liquefied gas container due to low temperatures, insulation modules are typically used to reduce heat exchange and ensure the stability of the liquefied gas. However, existing insulation modules still have shortcomings in terms of improving structural strength, construction safety, and space conservation. For example, common film enclosure systems typically 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 utilize a polyurethane sandwich structure between plywood. While this design effectively provides insulation, the polyurethane layer's low structural strength is susceptible to damage when subjected to high-intensity impacts, and the lack of effective support poses a safety hazard. Furthermore, existing structural designs fail to fully utilize the advantages of truss structures and fail to effectively improve the strength and stability of the insulation modules.

[0004] In order to solve the above problems, there is an urgent need for an improved design that can improve the strength and safety of the insulation module and simplify the construction process. Summary of the Invention

[0005] In view of this, in order to solve the problem that the polyurethane structure in the existing film enclosure system lacks effective support and is easily damaged by high-intensity impact. The purpose of the present invention is to propose an insulation module structure and a storage container thereof. The insulation module structure is mainly composed of a shielding group, an insulation module and an anchoring assembly. The design of the shielding group is further optimized. The shielding group and the insulation module are fixedly connected by an anchoring assembly, which increases the overall strength of the film enclosure system. At the same time, the anchoring assembly is improved, which can effectively improve the insulation performance, structural strength and construction safety of the storage container. Through the design of the grid structure, the stability of the formed film enclosure system is improved, and a lightweight design is achieved. To achieve the above object, the present invention provides the following technical solutions: Based on the above purpose, the present invention provides a thermal insulation module structure, which includes a shielding group, a thermal insulation module and an anchoring assembly, wherein the shielding group and the thermal insulation module are fixedly connected by the anchoring assembly; The shielding group includes a main shielding layer, a main plywood and a secondary shielding layer, wherein the main plywood is arranged between the main shielding layer and the secondary shielding layer; The thermal insulation module includes a first plywood, a second plywood, and a truss structure disposed between the first plywood and the second plywood, wherein the truss structure is enclosed and separated to form a plurality of thermal insulation filling areas, and the thermal insulation filling areas are filled with enhanced polyurethane foam; The first plywood is arranged on a side of the thermal insulation module close to the shielding group, and the shielding group, the first plywood and the truss structure are fixedly connected by the anchoring assembly.

The anchoring bolt is assembled in the anchoring assembly hole and passes through the main plywood, the secondary shielding layer and the first plywood and is threadedly connected to the blind hole anchoring tube.

[0007] In some embodiments, the truss structure is a grid-shaped reinforced frame formed by welding steel structures to each other, and an insulation board is embedded and fixed on the inner wall of the truss structure; corrugated areas and plane areas are provided on the main shielding layer and the secondary shielding layer, and the corrugated areas are staggered to surround the plane area, and the main plywood is located in the plane area, and the main plywood is distributed in the plane area in a matrix array, and the corrugated area limits and separates and fixes the main plywood distributed in the array, and the main shielding layer and the secondary shielding layer of the shielding group are metal films formed by bending technology.

[0008] In some embodiments, the four corners of the main plywood are provided with engaging grooves that fit with the inner walls of the primary shielding layer and the secondary shielding layer, which are fixed to the primary shielding layer and the secondary shielding layer after being bent and formed, and the side surfaces of the main plywood fit with the inner walls of the wavy separation areas of the primary shielding layer and the secondary shielding layer; the anchor assembly holes are located directly above the structural beams distributed transversely and longitudinally of the grid-like reinforced frame, and are used to enable the anchor assembly to fix the shielding group to the structural beams of the truss structure.

[0009] In some embodiments, a stop block is provided on the outer side wall of the blind hole anchoring tube to limit the position in the anchoring hole, and a secondary anchoring plate is sleeved on the blind hole anchoring tube, and the secondary anchoring plate is embedded in the upper surface of the first plywood.

The main shielding layer and the secondary shielding layer of the shielding group are bent to limit the array-distributed main plywood to form a shielding group.

[0011] In some embodiments, the truss structure of the insulation module is a rectangular frame with transverse and longitudinal distribution structural beams connected by columns, and the upper and lower rectangular frames, structural beams and columns are also connected by obliquely welded reinforcement columns.

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.

[0030] like Figures 1 to 9As shown, an embodiment of the present invention provides an insulation module structure, which includes a shielding group 1, an insulation module 3 and an anchoring assembly 16, and the shielding group 1 and the insulation module 3 are fixedly connected by the anchoring assembly 16; the shielding group 1 includes a main shielding layer 11, a main plywood 12 and a secondary shielding layer 13, and the main plywood 12 is arranged between the main shielding layer 11 and the secondary shielding layer 13; the insulation module 3 includes a first plywood 2, a second plywood 4 and a truss structure 31 arranged between the first plywood 2 and the second plywood 4, the truss structure 31 is enclosed and separated to form a plurality of insulation filling areas 33, and the insulation filling areas 33 are filled with enhanced polyurethane foam; the first plywood 2 is arranged between the shielding group 1 and the insulation module 3, and the shielding group 1 and the first plywood 2 are fixedly connected to the truss structure 31 by the anchoring assembly 16.

[0031] See Figure 5 and Figure 6 In this embodiment, the anchoring assembly 16 includes a blind hole anchoring tube 161, a secondary anchoring plate 162, an anchoring bolt 163 and a main anchoring plate 164. The truss structure 31 is provided with an anchoring hole 312 on the side close to the first plywood 2, and the cross-section of the anchoring hole 312 is convex. The blind hole anchoring tube 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 close to the secondary shielding layer, and the main anchoring plate 164 is embedded and installed on the side of the main plywood 12 close to the main shielding layer. The blind hole anchoring tube 161 passes through the first plywood 2, and the main plywood 12 is provided with an anchoring assembly hole 17 at the position corresponding to the anchoring hole 312. The cross-section of the anchoring assembly hole 17 is inverted convex. 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 tube 161.

[0032] See Figure 6 In this embodiment, a blind hole anchor tube 161 with a thread is arranged in the anchor hole 312 on the structural beam 311, and a stop block is provided on the outer wall of the blind hole anchor tube 161 to limit it in the anchor hole 312. The secondary anchor plate 162 is sleeved on the blind hole anchor tube 161, and the secondary anchor plate 162 is embedded in the upper surface of the first plywood 2. The anchor bolt 163 passes through the main plywood 12 and the secondary shielding layer 13 in sequence. The anchor assembly hole 17 is threadedly connected to the blind hole anchor tube 161, and the main anchor plate 164 is arranged above the anchor assembly hole 17 of the main plywood 12 and is fixedly connected to the main shielding layer 11. It plays the role of anchoring at a fixed point to cope with the stress of shrinkage of the main shielding layer 11 at low temperatures. 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.

[0033] See Figure 5In this embodiment, the truss structure 31 can be a grid-like reinforced frame formed by welding steel structures together. Insulation panels 32 are embedded and fixed to the inner wall of the truss structure 31. The insulation panels 32 separate the interior of the truss structure 31 into independent insulation filling areas 33, which are filled with reinforced polyurethane foam. A resin cement 5 is applied to the bottom of the second plywood 4 to securely connect the insulation module structure to the inner wall of the storage container. The resin cement 5 and the mounting base of the storage container inner wall form an anchor assembly 16.

[0034] See Figure 5 In this embodiment, the corrugated area 15 and the flat area 151 are set on the main shielding layer 11 and the secondary shielding layer 13. The corrugated area 15 is staggered to surround the flat area 151. The main plywood is located in the flat area 151. The main plywood 12 is distributed in a matrix array in the flat area 151. The corrugated area 15 limits and separates the main plywood 12 distributed in the array. The main shielding layer 11 and the secondary shielding layer 13 of the shielding group 1 are metal films formed by bending technology.

[0035] The present invention utilizes anchoring assemblies 16 to securely connect the truss structure 31 within the shielding assembly 1, significantly enhancing the overall structural strength. In particular, the metal film and truss structure 31 within the membrane enclosure system provide the entire structure with enhanced load-bearing capacity, effectively resisting the effects of external pressure and temperature fluctuations, and extending the service life of the storage container.

[0036] See Figure 8 The four corners of the main plywood 12 are provided with fitting grooves 121 that fit with the inner walls of the main shielding layer 11 and the secondary shielding layer 13. After bending and forming, they are fitted and fixed with the main shielding layer 11 and the secondary shielding layer 13. The side surfaces of the main plywood 12 fit with the inner walls of the wavy separation area between the main shielding layer 11 and the secondary shielding layer 13.

[0037] In this embodiment, in the shielding group 1, one end of the stud 14 is welded to the upper surface of the secondary shielding layer 13 and is connected and fixed to the nut in the main plywood 12, connecting and fixing the main plywood 12 and the secondary shielding layer 13. The main plywood 12 is arranged on the main shielding layer 11 and the secondary shielding layer 13 to form the shielding group 1.

[0038] 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 transversely and longitudinally of the grid-shaped reinforcement frame. The anchoring assembly holes 17 are rectangular grooves used for the anchoring components 16 to fix the shielding group 1 on the structural beams 311 of the truss structure 31.

[0039] Among them, the anchor assembly hole 17 can be an assembly groove of any shape such as a rectangular groove, a circular groove, etc., and a rectangular groove is preferably used in this embodiment. During installation, it can be first fixed by the anchor component 16 at the position of two anchor assembly holes 17 set in the same direction of the structural beam 311, and then fixed again by the anchor component 16 at the position of two rectangular assembly grooves rotated 45 degrees relative to the distribution direction of the lower structural beam 311. The shielding group 1 is fixed by four groups of anchor components 16 at the positions of the four anchor assembly holes 17, and the shielding group 1 is fixed to the structural beam 311 of the truss structure 31 through the anchor component 16.

[0040] In this embodiment, the shielding group 1 and the insulation module 3 can also be fixedly connected by an adjustable spring damping connection structure. The adjustable spring damping connection structure is connected by the shielding group 1, the insulation module 3 and the studs of the mounting base of the inner wall of the storage container. The studs are inserted into the mounting holes set in the vertical direction 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. The studs are provided with a spring and a limiting plate located on the outside of the spring in the mounting hole sleeve of the insulation module 3 section, and a damping medium is set in the mounting hole outside the limiting plate. After the studs are installed, insulating gap glass wool is provided in the mounting hole in the shielding group 1 for rigid insulation. After being fixedly connected by the adjustable spring damping connection structure, the free deformation of each independent module of the insulation module structure can be met while effective limitation can be performed.

[0041] 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 transversely and longitudinally. The structural beams 311 distributed transversely and longitudinally are fixedly connected to the shielding group 1 and the first plywood 2 through four groups of anchoring components 16. The main shielding layer 11 and the secondary shielding layer 13 of the shielding group 1 are bent to limit the 9 groups of main plywood 12 distributed in the array to form the shielding group 1.

[0042] In this embodiment, after the shielding group 1 is fixedly connected to the truss structure 31 of the insulation module 3 through the anchoring assembly 16 , the first plywood 2 is clamped and fixed between the shielding group 1 and the truss structure 31 .

[0043] 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, the structural beams 311, and the columns 313 are further connected by obliquely welded reinforcement columns 315. The reinforcement columns 315 divide the truss structure 31 into a number of triangular areas 316, which are filled with insulation panels 32. The columns inside each triangular area 316 of the grid-like reinforcement frame are provided with inner bevels 317. The inner bevels 317 are used to limit and block the insulation panels 32 installed from the inside of the truss structure 31 to the triangular areas 316. Figure 9 The insulation board 32 is provided with a stop inclined surface 321 which engages with the inner inclined surface 317 .

[0044] By setting a triangular area 316 on the side of the truss structure 31 and filling the insulation board 32 in this area, the strength and stability of the structure are further increased. In particular, the column design of the triangular area 316, combined with the inner bevel 317, effectively limits the displacement of the insulation board 32, ensuring long-term stability after filling with the enhanced polyurethane foam 34. The truss structure 31 of the present invention has been optimized and adopts a variety of structural units such as triangular areas 316, V-shaped reinforcement columns 315 and oblique tensile columns. These units can reasonably distribute and withstand external loads, avoid the problem of stress concentration, and improve the stability and reliability of the overall structure. By optimizing the structural design, the insulation module 3 is made more stable and durable. Due to its enhanced strength and stability, the maintenance requirements of the storage container are significantly reduced, the frequency of regular inspections and replacement of components is reduced, and thus the operating and maintenance costs are reduced.

[0045] In this embodiment, the insulation board 32 is filled in the truss structure 31, and forms an insulation cavity of the insulation module 3 in the insulation filling area 33 together with the first plywood 2 located above the truss structure 31 and the second plywood 4 located below. The first plywood 2 is arranged between the truss structure 31 and the shielding group 1, and the second plywood 4 is arranged between the truss structure 31 and the resin putty 5. The enhanced polyurethane foam 34 is filled in the insulation cavity to provide further thermal isolation performance.

[0046] Several strips of adhesive tape 5 are arranged on the bottom of the second plywood 4. Primary adhesive tape 51 is distributed beneath the rectangular frame 314 of the truss structure 31 and the structural beams 311. Several secondary adhesive tapes 52 are arranged between the primary adhesive tapes 51. The resin adhesive tape 5 is used to securely connect 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 adhesive tape 5 on the bottom of the second plywood 4 can be configured as adhesive tape, a bonding surface, or any other shape.

[0047] The embodiment of the present invention further provides a storage container having a heat-insulating module structure, wherein the heat-insulating module structure is fixedly connected to the inner wall of the storage container. Figure 10 As shown, the shielding group 1 and the insulation module 3 of the insulation module structure are fixed to the outer tank wall 7 and the inner side of the outer tank bottom 72 on the inner wall through the anchoring assembly 16, and a suspended ceiling insulation structure 73 is provided on the outer tank top 71. The pump structure 6 arranged in the storage container passes through the suspended ceiling insulation structure 73 and the outer tank top 71 in turn to be connected to the outside.

[0048] The storage container with an insulating module structure of the present invention can effectively reduce the loss of heat energy during the storage process of liquefied gas by setting up an insulating module structure, thereby improving energy utilization efficiency. More efficient thermal insulation performance means less energy consumption, and helps to reduce the environmental impact caused by excessive energy consumption. Through the structural design of the insulating module structure, especially in the connection method 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 and improves work efficiency. Through the design of the grid structure, the stability of the formed film enclosure system is improved, and a lightweight design is achieved. The truss structure 31 and the film enclosure system of the present invention can withstand extreme environmental conditions, can be applied to the liquefied gas storage needs of different regions, have stronger environmental adaptability, and ensure the reliability and stability of the container in various environments.
