Description

Technical Field

[0001] The present invention generally relates to the field of containers, and more particularly to a tank body and a tank container having the same. Background Art

[0025] In the discussion below, details are given to provide a more thorough understanding of the present invention. However, it will be appreciated by those skilled in the art that the present invention can be implemented without one or more of these details. In certain examples, some technical features known in the art are not described in detail to avoid confusion with the present invention. It should be noted that the terms "upper", "lower", "front", "back", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0026] The tank body and the tank container having the tank body shown in the present invention are described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 1 and Figure 2 1 is a tank container according to a preferred embodiment of the present invention, which includes a tank body 10 and a frame 20. The tank body 10 is substantially in the shape of a long cylinder and is disposed inside the frame 20. The cross section of the frame 20 perpendicular to the axial direction of the tank body 10 (i.e., the length direction of the tank container) is square, in other words, the frame 20 is substantially in the shape of a cuboid.

[0028] like Figure 1As shown, the frame 20 includes a bottom frame 21 and an end frame 22. The bottom frame 21 has four edges along the length direction that constitute the rectangular shape of the frame 20, and it extends roughly in a direction parallel to the axial direction of the tank body 10. The tank body 10 is located in the space surrounded by the four edges of the bottom frame 21, and is fixedly connected to the bottom frame 21 by external reinforcements 12 and various connectors, reinforcement ribs, etc. The bottom frame 21 is used to support the tank body 10 and plays a role in fixing and protecting it. End frames 22 are provided at both ends of the bottom frame 21. The end frames 22 are located on the outside of the two ends of the tank body 10, so that the tank body 10 is completely contained in the frame 20. As shown Figure 2 As shown, the end frame 22 is connected to the head (not shown) of the tank body 10 through a skirt ring 23 (shown in dotted lines). This can further ensure the overall stability of the frame 20 and the connection strength between the frame 20 and the tank body 10, strengthen the support of the frame 20 on the tank body 10, and thus improve the bearing capacity of the tank body 10.

[0029] The tank body 10 provides a carrying space for the tank container. Therefore, under the premise of a certain size, it is hoped that the volume of the tank body 10 is maximized as much as possible, while also ensuring that the strength of the tank body 10 meets the standard specifications. Figure 1 As shown, the tank body 10 mainly includes a cylinder 11, an external reinforcement 12, an internal reinforcement 13 and a head. The cylinder 11 mainly provides a storage space for the tank body 10, the head is used to seal both ends of the cylinder 11, and the external reinforcement 12 and the internal reinforcement 13 are respectively connected to the outer surface and the inner surface of the cylinder 11 to increase the strength of the cylinder 11.

[0030] The cylinder 11 is roughly in the shape of a long cylinder. The cross section of the cylinder 11 perpendicular to its own axis is formed by eight segments of concentric circular arcs connected smoothly. Such a structure makes the cross-sectional area of ​​the cylinder 11 larger than the area of ​​a circle with the width of the cylinder 11 as the diameter. Therefore, under the premise of a certain length, the space surrounded by the cylinder 11 can be increased, that is, the volume of the tank 10 is increased. Specifically, the eight concentric circular arcs constituting the cross section of the cylinder 11 include two first circular arcs 111, two second circular arcs 112 and four third circular arcs 113. Among them, the two first circular arcs 111 are arranged opposite to each other on the left and right, and the two second circular arcs 112 are arranged opposite to each other on the top and bottom. The chord of the first circular arc 111 is arranged roughly in the vertical direction, and the chord of the second circular arc 112 is arranged roughly in the horizontal direction. The first circular arc 111 and the second circular arc 112 constitute the main part of the cross section of the cylinder 11, so the two have a larger diameter. However, there is no limitation on the relative relationship between the diameters of the two, and the diameter of the first arc 111 can be greater than, equal to or less than the diameter of the second arc 112. The four third arcs 113 are respectively arranged between the adjacent first arcs 111 and the second arc 112, that is, the four third arcs 113 are respectively located at the upper left, lower left, upper right and lower right of the cross section of the cylinder 11. The third arc 113 has the smallest diameter among the three arcs, and is mainly used to smoothly connect the adjacent first arcs 111 and the second arc 112. In this way, the surface of the cylinder 11 can be smoother, avoiding stress concentration when bearing internal and external loads, and further improving the bearing capacity of the tank 10; the cylinder 11 formed by the smooth connection of multiple arc surfaces can make full use of the limited size space in the frame 20, ensuring the maximization of the volume of the tank 10; in addition, the smooth arc is easier to shape during processing, simplifying the processing procedures. It can be understood that the cross section of the cylinder 11 can also be formed by smoothly connecting curves other than arcs, for example, by a parabola and arcs that smoothly connect each segment of the parabola.

[0031] Preferably, the cylinder 11 can be formed by continuously bending a whole sheet of sheet material to form various arc surface parts, and then welding the adjacent sides. In this way, the cylinder 11 has only one weld in the axial direction, which greatly reduces the risk of leakage of the tank 10 during use and improves the reliability of the tank 10 during operation. In addition, the integrally formed cylinder 11 has a high load resistance, which can reduce the number of reinforcement parts used, thereby reducing the deadweight of the tank 10 and effectively improving the load-bearing capacity of the tank container.

[0032] According to the tank body 10 of this embodiment, although its volume is effectively increased compared with the tank body with a circular cross section, its pressure resistance is reduced, and it is easy to deform when subjected to a large pressure from inside or outside. Therefore, an external reinforcement 12 is provided to prevent the cross section of the cylinder body 11 from being deformed due to the pressure.

[0033] like Figure 1 As shown, the external reinforcement 12 is fixedly connected to the outer surface of the cylinder 11, extends along the circumferential direction of the cylinder 11 and surrounds the cylinder 11, playing a role similar to a tight hoop. Preferably, the cross section of the external reinforcement 12 itself is an "I" shape, that is, the external reinforcement 12 is roughly an annular structure with an "I"-shaped cross section along the radial direction. The "I"-shaped member has a high strength and can play a good role in reinforcement. Figure 1 As shown, the external reinforcement 12 includes an inner ring 121, an intermediate plate 122 and an outer ring 123. The inner ring 121 and the outer ring 123 are both roughly constructed in an annular shape and have a width along the annular axis. The intermediate plate 122 is fixedly connected to the outer surface of the inner ring 121 and the inner surface of the outer ring 123, respectively, and the intermediate plate 122 is perpendicular to the inner ring 121 and the outer ring 123 to form an "I"-shaped cross-section along the annular axis. The inner surface of the inner ring 121 fits tightly with the outer surface of the cylinder 11. It should be noted that in the cross section of the tank container, the external reinforcement 12 is located within the range of the frame 20. In other words, the outer wall of the external reinforcement 12 does not exceed the size range of the frame 20 to prevent the reinforcement effect of the external reinforcement 12 from being affected by collisions during transportation and handling.

[0034] The height of the outer wall of the external reinforcement 12 protruding from the outer surface of the cylinder 11 varies along the circumference of the cylinder 11, that is, the height of the middle plate 122 protruding outward from the outer surface of the inner ring 121 varies. In this way, the external reinforcement 12 can be selectively arranged. In the position where the deformation tendency of the cylinder 11 is greater, the protruding height of the outer wall of the external reinforcement 12 is increased, thereby increasing the strength; in the position where the deformation tendency of the cylinder 11 is smaller, the protruding height of the outer wall of the external reinforcement 12 is reduced, which can save materials and reduce the dead weight of the tank 10. Preferably, Figure 2 As shown, at the center line of the first arc 111 located on the left and right sides, the protruding height of the outer reinforcement 12 can be set to zero. According to industry standards, the width of the tank container is constant, that is, the width of the frame 20 is constant. Such a setting can make the outer reinforcement 12 not occupy space in the width direction, thereby expanding the width of the cylinder 11 as much as possible and increasing the volume.

[0035] The external reinforcement 12 can effectively resist the influence of the internal pressure of the cylinder 11 on the outward deformation of the cylinder 11. However, the influence of the external pressure on the inward deformation of the cylinder 11 is relatively weak, especially at the position where the outer wall protrusion height of the external reinforcement 12 is small. Therefore, an internal reinforcement 13 is provided for reinforcement. The internal reinforcement 13 is connected to the inner surface of the cylinder 11. Different from the external reinforcement 12, the internal reinforcement 13 is not a ring-shaped one surrounding the whole body, but is provided in sections along the circumference of the cylinder 11. The internal reinforcement 13 is preferably provided at the corresponding position where the protrusion height of the external reinforcement 12 is small. Figure 1 and Figure 2 As shown, the internal reinforcement 13 includes a first reinforcement plate 131 and a second reinforcement plate 132. The first reinforcement plate 131 is arranged perpendicular to the inner surface of the cylinder 11, and the second reinforcement plate 132 is perpendicularly connected to the side of the first reinforcement plate 131 away from the cylinder 11, so that the cross section of the internal reinforcement 13 is "T" shaped. The "T" shaped reinforcement has good strength and obvious reinforcement effect. Preferably, the height of the first reinforcement plate 131 protruding from the inner surface of the cylinder 11 is different, so that the second reinforcement plate 132 is a flat plate.

[0036] In this embodiment, the reinforcement effect of the external reinforcement member 12 at the center line of the two first arcs 111 on the left and right sides is weak, so the internal reinforcement member 13 is connected to the inner side of the two first arcs 111 on the left and right sides to provide additional reinforcement, and the length of the internal reinforcement member 13 is approximately equal to the length of the chord of the first arc 111. In this way, the internal reinforcement member 13 is only arranged on the side wall of the cylinder 11. Compared with the annular reinforcement member, the inner surface of the upper and lower walls is kept smooth and flat, which is easy to clean. At the same time, the volume inside the tank body 10 is expanded, and the loading capacity of the tank container is improved; and the internal reinforcement member 13 can effectively save materials and reduce the dead weight of the tank container, thereby reducing the production cost and transportation cost. In other embodiments, the internal reinforcement member can also be arranged at other positions inside the cylinder. Preferably, a series of circular through holes 133 are arranged on the first reinforcement plate 131, which can effectively reduce the impact of the internal reinforcement member 13 during the use of the tank container and extend the service life. Of course, the through hole 133 can also be other shapes.

[0037] It can be understood that a plurality of external reinforcement members and / or internal reinforcement members may be included on the same tank body 10 , and the plurality of external reinforcement members and / or internal reinforcement members may be evenly spaced apart along the length direction of the tank body 10 .

[0038] The tank body and the tank container having the same according to the present invention utilize the cooperation of external reinforcement members and internal reinforcement members to ensure the strength of the tank body and improve the carrying capacity; at the same time, the volume of the tank body is maximized and the cargo carrying capacity is increased; the internal structure is simple, the inner surface is smooth, and it is easy to clean, which saves materials and effectively reduces the dead weight, thereby reducing costs.
