Description

Containers used for storing and transporting liquid materials

[0001] This application claims priority to Chinese patent application filed on September 2, 2024, application number CN 202422145887.5, entitled "Container for storing and transporting liquid materials", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of container technology, and more specifically to a container for storing and transporting liquid materials. Background Technology

[0003] With the development of the global economy, containers, as an important means of transportation in international goods trade, are increasingly widely used, and the types of goods transported are becoming more diversified. For the transportation of different types of special goods, custom-developed special containers are often used. Currently, for multimodal transport of liquid cargo, tank containers are the most mainstream mode of transport. However, because the tanks of commonly used tank containers are cylindrical with butterfly caps at both ends, their internal volume is relatively small compared to a cuboid of the same length, width, and height, making it difficult to meet the requirements of some customers for cargo loading capacity and lightweight design. Summary of the Invention

[0034] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0035] This disclosure provides a container for storing and transporting liquid materials.

[0036] Exemplary embodiments according to this disclosure will now be described in more detail with reference to the accompanying drawings.

[0037] As shown in Figures 1 and 2, in a specific embodiment, the square container 100 according to this disclosure can be used for storing and transporting liquid materials. In this disclosure, the container 100 can also be referred to as a square box 100. With the same length, width, and height dimensions, a square box has a larger volume than a circular tank container.

[0038] The container 100 has a rectangular frame formed by multiple beams (two bottom side beams 17A, two top side beams 17B, two bottom end beams 18A, and two top end beams 18B) connected to four corner posts 10. A top panel 11, floor 12, left side wall 13, right side wall 14, front wall 15, and rear wall 16 are installed to this frame. The top panel 11 and floor 12 are spaced apart along the height direction DH of the container 100. The left side wall 13 and right side wall 14 are spaced apart along the width direction DW of the container 100. The front wall 15 and rear wall 16 are spaced apart along the length direction DL of the container 100. The corner posts 10 extend vertically, and the left side wall 13, right side wall 14, front wall 15, and rear wall 16 all extend in a vertical plane, making the container 100 generally a cuboid structure. The top panel 11, floor 12, left side wall 13, right side wall 14, front wall 15, and rear wall 16 together enclose the internal space 19 of the container 100. The interior space 19 is used to accommodate materials (cargo), especially liquid materials. The top panel 11, floor 12, left side wall 13, right side wall 14, front wall 15, and rear wall 16 are also the outer walls of the container 100. The left side wall 13, right side wall 14, front wall 15, and rear wall 16 are also referred to as the walls of the container 100.

[0039] The top plate 11 is provided with a manhole 71 for personnel passage and also serves as a feed inlet (liquid materials flow into the internal space 19 through the manhole 71). The manhole 71 is usually covered. The rear end wall 16 is provided with a discharge port (not shown) from which liquid materials flow out of the internal space 19. A discharge valve is usually provided at the discharge port, and the discharge port opens when the discharge valve is open. A cover may also be provided at the discharge port to prevent accidental contact with the discharge valve. The top plate 11 is also provided with a venting device 70 for ventilating the internal space 19 with the external environment. The venting device 70 can be, for example, a valve, which connects the internal space 19 to the external environment when the valve is open. When unloading is required, the venting device 70 is first operated to ventilate the internal space 19 with the external environment to maintain consistent air pressure, and then the discharge valve is opened so that air can be continuously replenished into the internal space 19, balancing the internal and external pressures of the container 100, thus preventing the outer wall of the container 100 from deforming due to pressure imbalance.

[0040] To reduce surges caused by liquids during transport, at least one wave deflector 20 is installed inside the container 100. The wave deflector 20 is generally perpendicular to the length direction DL of the container 100, that is, generally parallel to the front wall 15 and the rear wall 16. As shown in Figures 2 and 4, the container 100 may include multiple wave deflectors 20, which are spaced apart along the length direction DL of the container 100. The wave deflectors 20 divide the internal space 19 into several smaller spaces, ensuring that liquids in the internal space 19 can only swirl within the smaller spaces between two adjacent wave deflectors 20, thereby reducing surges and improving the safety factor.

[0041] The wave deflector 20 may be provided with openings or notches for personnel passage. As shown in Figures 2 and 4, the wave deflector 20 may also have gaps with the sidewall on the left or right side, forming notches for personnel passage. Each wave deflector 20 corresponds to one opening or notch. Optionally, the two openings or notches corresponding to two adjacent wave deflectors 20 are not aligned, or in other words, in the projection of the container 100 along the length direction DL, the two openings or notches corresponding to two adjacent wave deflectors 20 do not overlap, to avoid excessive local surge at the opening or notch.

[0042] To reduce the overall weight of the container 100 while maintaining the strength of the outer walls, as shown in Figures 2 to 4, optionally, at least one of the front and rear end walls (15 and 16) and the left and right side walls (13 and 14) includes a corrugated plate 80. The corrugated plate 80 extends vertically. Optionally, all four end walls (15 and 16) and side walls (13 and 14) are constructed using corrugated plate 80. The two end walls (15 and 16) are each supported by two bottom end beams 18A. The two side walls (13 and 14) are each supported by two bottom side beams 17A. The two bottom end beams 18A and the two bottom side beams 17A can be collectively referred to as the bottom beams of the container 100. Therefore, the corrugated plate 80 is supported by the bottom beams, or in other words, the bottom of the corrugated plate 80 is connected to the bottom beams, for example, to the upper surface of the bottom beams. The top of the corrugated sheet 80 is connected to the top beam of the container 100 (e.g., top side beam 17B and / or top beam 18B), such as the lower surface of the top beam.

[0043] As shown in Figure 5, the corrugated plate 80 includes multiple convex waves 81 and multiple concave waves 82, which are arranged alternately. The convex waves 81 and concave waves 82 are also referred to as waves of the corrugated plate 80. In this disclosure, the convex waves 81 and concave waves 82 are defined from the perspective of viewing the corrugated plate 80 from the interior space 19; the portion protruding towards the interior space 19 is the convex wave 81, and the portion protruding towards the exterior of the container 100 is the concave wave 82. The corrugated plate 80 has a wavy shape, including alternating crests 83 and troughs 84, and connecting portions 85 connecting adjacent crests 83 and troughs 84. A crest 83 and the connecting portions 85 on both sides constitute a convex wave 81. A trough 84 and the connecting portions 85 on both sides constitute a concave wave 82. The arrangement direction of the convex waves 81 and concave waves 82 is the corrugation width direction DCW. The extension direction of the convex waves 81 and concave waves 82 is the corrugation length direction DCL. The corrugated plate 80 has a corrugated shape with the corrugation depth direction DCD. Optionally, the corrugation width direction DCW, the corrugation length direction DCL, and the corrugation depth direction DCD are all perpendicular to each other.

[0044] To enhance the strength of the corrugated sheet 80, the wave depth DD of at least one wave (convex wave 81 or concave wave 82) of the corrugated sheet 80 is greater than 100 mm, for example, greater than or equal to 110 mm. Since liquids are in a free state, acceleration and braking during vehicle movement cause the liquid to surge back and forth. When the vehicle is turning, the liquid will surge to one side under centrifugal force. All of these situations will cause significant impact on the walls of the "transport container," easily leading to damage and affecting transportation safety. Existing ordinary dry cargo containers typically use corrugated sheet structures with a wave depth of 36 mm on both side panels, while ordinary bulk cargo containers usually use corrugated sheet structures with a wave depth of 48-60 mm. For liquid cargo transportation, ordinary dry cargo containers and ordinary bulk cargo containers do not possess the load-bearing capacity required for transporting liquid cargo. This disclosure increases the strength of the corrugated sheet by increasing its wave depth, thereby making the container suitable for transporting liquids.

[0045] Furthermore, at corrugated sections where the wave depth DD is greater than 100 mm, the thickness DT of the corrugated plate 80 is greater than or equal to 2.6 mm, for example, greater than or equal to 2.6 mm and less than or equal to 4 mm. Thus, the strength of the corrugated plate 80 is ensured through the coordination of the wave depth DD and the plate thickness DT. In this disclosure, by increasing the wave depth and reasonably controlling the corrugated plate thickness, a significant increase in the box's self-weight can be avoided, reducing the load capacity and thus preventing increased transportation costs. In addition, as the plate thickness increases, the forming process becomes more difficult and prone to cracking, making it difficult to guarantee quality.

[0046] At least one wave of the corrugated plate 80 with a wave depth DD greater than 100 mm can be a wave of the corrugated plate 80 from any one of the front wall 15, rear wall 16, left wall 13, and right wall 14. Optionally, each of the front wall 15, rear wall 16, left wall 13, and right wall 14 includes at least one wave that meets the dual requirements of wave depth DD and plate thickness DT.

[0047] Optionally, the wave depth DD of all the waves of the corrugated plate 80 is greater than 100 mm, for example, greater than or equal to 110 mm. Further, the plate thickness DT of the corrugated plate 80 is greater than or equal to 2.6 mm, for example, greater than or equal to 2.6 mm and less than or equal to 4 mm.

[0048] All corrugated sheets 80 of container 100 can be made of corrugated sheets of uniform specifications, or they can be spliced ​​together from corrugated sheets 80 of different specifications. For example, while meeting strength requirements, corrugated sheets 80 with different wave depths DD, different sheet thicknesses DT, and different waveforms can be selected to splice the outer wall, in order to achieve the goals of weight reduction, cost reduction, and reduction of process steps. For example, the corrugated sheet 80 includes a first corrugated sheet and a second corrugated sheet, wherein the first corrugated sheet and the second corrugated sheet differ in at least one of wave depth DD, sheet thickness DT, and waveform. The outer walls of different sides of container 100 are respectively made of the first corrugated sheet and the second corrugated sheet; or, the outer wall of the same side of container 100 is made of spliced ​​first corrugated sheets and second corrugated sheets, for example, the first corrugated sheets and the second corrugated sheets are arranged alternately.

[0049] For example, the corrugated plate 80 used for the end wall (15 or 16) may or may not have the same specifications as the corrugated plate 80 used for the side wall (13 or 14). Specifically, the corrugation depth DD of the corrugated plate 80 used for the end wall (15 or 16) may or may not have the same corrugation depth DD as the corrugated plate 80 used for the side wall (13 or 14). Alternatively, the waveform of the corrugated plate 80 used for the end wall (15 or 16) may or may not have the same waveform as the corrugated plate 80 used for the side wall (13 or 14). Alternatively, the plate thickness DT of the corrugated plate 80 used for the end wall (15 or 16) may or may not have the same thickness DT as the corrugated plate 80 used for the side wall (13 or 14). For example, the corrugation depth DD of the corrugated plate 80 used for the end wall (15 or 16) may be greater than the corrugation depth DD of the corrugated plate 80 used for the side wall (13 or 14). For example, the thickness DT of the corrugated plate 80 used for the end wall (15 or 16) is greater than the thickness DT of the corrugated plate 80 used for the side wall (13 or 14).

[0050] The same end wall (15 or 16) can use corrugated plates of the same specification or corrugated plates of different specifications spliced ​​together. Therefore, the corrugation depth DD of the corrugated plates 80 used for the same end wall (15 or 16) can be the same or different, the plate thickness DT of the corrugated plates 80 used for the same end wall (15 or 16) can be the same or different, and the waveform of the corrugated plates 80 used for the same end wall (15 or 16) can be the same or different.

[0051] Similarly, the same sidewall (13 or 14) can use corrugated plates of the same specification or corrugated plates of different specifications spliced ​​together. Therefore, the corrugation depth DD of the corrugated plates 80 used for the same sidewall (13 or 14) can be the same or different, the plate thickness DT of the corrugated plates 80 used for the same sidewall (13 or 14) can be the same or different, and the waveform of the corrugated plates 80 used for the same sidewall (13 or 14) can be the same or different.

[0052] The wave deflector 20 can also be made of corrugated sheet 80, further unifying the materials of the container 100. When used as a wave deflector, the corrugated length direction DCL of the corrugated sheet 80 can be vertical (see Figure 2) or horizontal.

[0053] In the cross-section of the corrugated plate 80 (the section perpendicular to the corrugation length direction DCL), the planar dimensions of the convex waves 81 and concave waves 82 of the corrugated plate 80 may be the same or different. In other words, the cross-sections of the convex waves 81 and concave waves 82 may be congruent or non-congruent. For example, the convex waves 81 and concave waves 82 may have different shapes. For instance, one of the crests 83 and troughs 84 may be curved, while the other may be straight. Alternatively, the convex waves 81 and concave waves 82 may have different widths. As shown in Figure 5, the width of the convex waves 81 is smaller than the width of the concave waves 82. Those skilled in the art can also construct the convex waves 81 and concave waves 82 with different planar dimensions in other ways.

[0054] The corrugated plate 80 can have different wave shapes. For example, the cross-section of the wave can be a serpentine curve or a broken line. In the broken line type shown in Figure 5, the crest 83, trough 84, and connecting portion 85 are all generally flat plates. That is, in the projection of the corrugated plate 80 along the corrugation length direction DCL (that is, in the cross-section of the corrugated plate 80 perpendicular to the corrugation length direction DCL), the crest 83, trough 84, and connecting portion 85 all extend at least partially along a straight line (as straight line segments). Thus, both the convex wave 81 and the concave wave 82 are C-shaped broken lines.

[0055] For example, in a cross-section of the corrugated plate 80 perpendicular to the corrugation length direction DCL, at least a portion of the crest portion 83 is constructed to extend along a first straight line L1, at least a portion of the trough portion 84 is constructed to extend along a second straight line L2, and at least a portion of the connecting portion 85 is constructed to extend along a third straight line L3. Optionally, the crest portion 83 is generally constructed to extend along the first straight line L1, the trough portion 84 is generally constructed to extend along the second straight line L2, and the connecting portion 85 is generally constructed to extend along the third straight line L3. Here, "generally constructed to extend along a straight line" means that the remaining portion of the component, except for the portions at both ends of the component that connect to other components, is constructed to extend along a straight line. The portions at both ends of the component that connect to other components are, for example, a portion of a rounded corner. In other words, the ideal structure for the crest portion 83, the trough portion 84, and the connecting portion 85 is to extend along a straight line, but for manufacturing considerations, the connecting portions of each pair are constructed with rounded corners.

[0056] Optionally, the first straight line L1 of the crest portion 83 and the second straight line L2 of the trough portion 84 are parallel to each other.

[0057] The third straight line L3 of the connecting portion 85 does not intersect perpendicularly with the first straight line L1 of the crest portion 83. The third straight line L3 of the connecting portion 85 does not intersect perpendicularly with the second straight line L2 of the trough portion 84. The angle α1 between the third straight line L3 of the connecting portion 85 and the first straight line L1 of the crest portion 83 within the convex wave 81 is an obtuse angle. The angle α2 between the third straight line L3 of the connecting portion 85 and the second straight line L2 of the trough portion 84 within the concave wave 82 is an obtuse angle. The inclined arrangement of the connecting portion 85 contributes to improving the load-bearing capacity of the corrugated plate 80 and also makes the corrugated plate 80 easier to process.

[0058] Optionally, the width of the portion extending along the second straight line L2 of the trough portion 84 is configured such that its width ranges from [100, 400] mm. Optionally, the width of the portion extending along the first straight line L1 of the crest portion 83 is configured such that its width ranges from [100, 400] mm. The width of the straight portion of the trough portion 84 can be the same as or different from the width of the straight portion of the adjacent crest portion 83. Optionally, in the projection of the corrugated plate 80 along the corrugation length direction DCL, the length W1 of the projection of the connecting portion 85 onto the first straight line L1 of the crest portion 83 is not less than 15 mm. Optionally, in the projection of the corrugated plate 80 along the corrugation length direction DCL, the length W2 of the projection of the connecting portion 85 onto the second straight line L2 of the trough portion 84 is not less than 15 mm.

[0059] Optionally, the convex wave 81 has an axisymmetric structure symmetrical about a first axis of symmetry A1, which extends along the wave depth direction DCD. Optionally, the concave wave 82 has an axisymmetric structure symmetrical about a second axis of symmetry A2, which extends along the wave depth direction DCD.

[0060] Optionally, the corrugated plate 80 is constructed such that, within a width of 1m, it includes at least one convex wave 81 and at least one concave wave 82. That is, the interval between corresponding positions of two adjacent convex waves 81 does not exceed 1m, and the interval between corresponding positions of two adjacent concave waves 82 does not exceed 1m. The width of the crest portion 83 and the inclination of the connecting portion 85 determine the width of the convex wave 81. The width of the trough portion 84 and the inclination of the connecting portion 85 determine the width of the concave wave 82. In this disclosure, the convex wave 81 and the concave wave 82 have suitable widths. If the wave width is too large, the strength of the corrugated plate 80 cannot be guaranteed. If the wave width is too small, it will increase material usage, raise costs, and reduce the volume of the internal space 19.

[0061] Table 1 compares the moments of inertia of the cross sections of containers using corrugated sheets with different corrugation depths. Container 1 is a general dry cargo container (corrugation depth 36mm), Container 2 is a bulk cargo container (corrugation depth 50mm), Container 3 is a bulk cargo container (corrugation depth 60mm), Container 4 is a liquid container (corrugation depth 100mm), and Container 5 is a liquid container (corrugation depth 110mm).

[0062] Table 1 Comparison of the moment of inertia of the cross sections of containers using corrugated sheets with different corrugation depths

[0063] As shown in Table 1, the deeper the corrugation, the greater the moment of inertia of the cross section, and the higher the corresponding bending stiffness (bending stiffness is the product of the moment of inertia and the modulus of elasticity). When the corrugation depth of the corrugated plate reaches 100 mm, the moment of inertia can reach 75.9 × 10⁻⁶ mm. 5 (mm 4 This design can well meet the needs of liquid loading. Furthermore, by increasing the wave depth, the number of waves in a single plate (e.g., a plate width of 1116mm) can be reduced while still meeting strength requirements, thereby saving materials and improving production efficiency, while also meeting lightweight design requirements.

[0064] This disclosure provides a corrugated wall panel design that meets strength requirements. By designing the corrugation depth of the corrugated plate to be greater than 100mm, the strength of the corrugated plate can meet the requirements for liquid transportation. This breaks through the traditional method of transporting liquids using tank containers, enabling square containers to also transport liquids, leveraging their large volume advantage to load more liquid at once, reducing logistics costs, saving transportation resources, and reducing carbon emissions. While ensuring the corrugation depth, the container's outer wall does not require reinforcing beams, avoiding increased processing difficulty and manufacturing costs, thus reducing manufacturing difficulty and production costs to a certain extent. Simultaneously, it avoids increasing the container's weight, which would affect cargo loading capacity.

Unless adverse effects occur, various processing operations can be performed in a different order than those described above. The order of steps in the above process can also be added, combined, or deleted according to actual needs.
