Description

Technical Field

[0001] This utility model relates to the field of cargo transportation technology, specifically providing a liquid bag for transporting bulk fluids. Background Technology

[0002] As a robust and standardized loading tool, shipping containers can be used to transport fluid goods. In the current logistics field, the use of containers for fluid transportation has become a widely adopted new large-scale transportation mode. Its core lies in the combined use of containers and soft liquid bags specially designed for fluids. These container fluid bags can effectively replace traditional packaging forms such as tanks and iron drums, which are more expensive. They are suitable for various transportation routes such as sea, rail, and road.

[0003] While containerized fluid bags have demonstrated high efficiency in transporting large fluid cargo, the fluid's fluidity also presents challenges: during transport, the fluid can easily slosh around inside the container, which can not only cause the fluid bags to break but also lead to serious safety accidents, such as the transport vehicle overturning and causing casualties.

[0004] To avoid this situation, existing technologies often use ropes, supports, etc., to firmly fix the liquid bags inside the container to prevent them from shaking or shifting during transportation. However, the fixing effect is limited, and the liquid bags may still be damaged due to shaking during transportation. Moreover, this method is not effective in suppressing the shaking of fluid cargo, and it is difficult to ensure the installation during transportation. During long-term transportation or when encountering severe bumps, the ropes or supports may loosen or be damaged.

[0005] In summary, existing liquid bags are not effective at suppressing shaking during transportation and are easily damaged by shaking.

[0006] Accordingly, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0007] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that existing liquid bags are not effective in suppressing shaking during transportation and are easily damaged due to shaking.

[0008] This utility model provides a liquid bag for transporting bulk fluids. The liquid bag includes a bag body, in which a fluid storage space is formed. The bag body is provided with a fluid inlet and a fluid outlet that are connected to the fluid storage space. A partition is provided in the fluid storage space, and the partition is configured to block the flow of fluid in the fluid storage space.

[0009] In the preferred embodiment of the liquid bag described above, there are multiple partitions, which divide the fluid storage space into multiple fluid chambers, and the multiple fluid chambers are directly or indirectly connected.

[0010] In the preferred embodiment of the liquid bag described above, each of the partitions forms a gap with the inner bottom wall of the bag body, and the multiple fluid chambers are directly or indirectly connected through the gaps.

[0011] In the preferred embodiment of the liquid bag described above, each of the partitions forms a gap with the inner sidewall of the bag body, and the plurality of fluid chambers are directly or indirectly connected through the gaps.

[0012] In the preferred embodiment of the liquid bag described above, each of the partitions forms a gap with the inner top wall of the bag body, and the multiple fluid chambers are directly or indirectly connected through the gaps.

[0013] In the preferred embodiment of the liquid bag described above, each of the partitions forms a gap with at least one of the inner bottom wall, inner side wall, and inner top wall of the bag body, and the plurality of fluid chambers are directly or indirectly connected through the gaps.

[0014] In the preferred embodiment of the liquid bag described above, each of the partitions is provided with a notch, and the plurality of fluid chambers are connected sequentially through the notches.

[0015] In the preferred embodiment of the liquid bag described above, the lateral projections of the multiple notches coincide; or, the lateral projections of the multiple notches are arranged vertically; or, the lateral projections of the multiple notches are arranged horizontally; or, the line segment connecting the center points of the lateral projections of the multiple notches is an inclined line segment; or, the lateral projections of the multiple notches are distributed in an array.

[0016] In the preferred embodiment of the liquid bag described above, the bag body is composed of multiple bag pieces spliced ​​together, and the liquid bag also includes an outer bag that wraps around and covers the bag body.

[0017] In the preferred embodiment of the liquid bag described above, the bag body and / or the partition are made of PE, PP, PVC or TPU.

[0018] With the above technical solution adopted, the liquid bag of this utility model for transporting bulk fluids includes a bag body, a fluid storage space formed inside the bag body, and a partition installed within the fluid storage space. The partition is configured to block the flow of fluid within the fluid storage space. By installing a partition within the fluid storage space, this utility model divides a large volume of bulk fluid into multiple smaller volumes, effectively preventing large-volume bulk fluid from swaying significantly. Compared to external fixing methods (ropes or supports), installing partitions internally is more adaptable to various transportation conditions, including severe bumps and long-term transportation, significantly improving the effect of suppressing fluid swaying.

[0019] Furthermore, this invention also forms a gap between the partition and the inner bottom wall of the bag body, which allows multiple fluid chambers to be directly or indirectly connected at the bottom of the liquid bag. At the same time, since the fluid outlet of the container is located at the bottom, the fluid can be released from the bottom of the liquid bag after the fluid outlet is connected to the fluid outlet. By forming a gap between the partition and the inner bottom wall of the bag body, regardless of the amount of fluid in the liquid bag, it can effectively prevent shaking and facilitate the discharge of fluid, without requiring any modification to the structure of the container.

[0020] Furthermore, the bag body of this utility model is composed of multiple bag pieces spliced ​​together, and the outer bag is used to wrap and cover the bag body, thereby effectively preventing the bag body from being worn and leaking during transportation; this design not only increases the overall sealing of the liquid bag, but the outer bag also provides an extra layer of protection for the inner bag, which can enhance the overall strength of the bag body, which is especially important for liquid bags that need to withstand high pressure or weight.

[0033] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0034] It should be noted that in the description of this utility model, the terms "upper," "lower," "left," "right," "front," and "rear," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] First refer to Figure 1 and Figure 2 ,like Figure 1 and Figure 2As shown, the liquid bag for transporting bulk fluids of this utility model includes a bag body 1, a fluid storage space 11 formed inside the bag body 1, a fluid inlet 12 and a fluid outlet 13 connected to the fluid storage space 11 on the bag body 1; a partition 2 is provided inside the fluid storage space 11, and the partition 2 is configured to block the flow of fluid in the fluid storage space 11.

[0037] Based on the above structural configuration, a partition 2 is installed in the fluid storage space 11 to divide the large volume of bulk fluid into multiple smaller volumes, effectively preventing the large volume of bulk fluid from shaking significantly and avoiding damage to the liquid bag. Compared with external fixing methods (ropes or brackets) installed internally, the partition 2 is more adaptable to various transportation conditions, including severe bumps and long-term transportation, significantly improving the effect of suppressing fluid shaking.

[0038] Preferably, there are multiple partitions 2, which divide the fluid storage space 11 into multiple fluid chambers. These fluid chambers are directly or indirectly connected, meaning that fluid can circulate within them. Specifically, as shown... Figure 1 and 2 As shown, there are 5 partitions 2, which are, from left to right, the first partition 21, the second partition 22, the third partition 23, the fourth partition 24, and the fifth partition 25. The 5 partitions 2 divide the fluid storage space 11 into 6 fluid chambers, which are, from left to right, the first fluid chamber 111, the second fluid chamber 112, the third fluid chamber 113, the fourth fluid chamber 114, the fifth fluid chamber 115, and the sixth fluid chamber 116. The fluid in the six fluid chambers can flow to each other. Of course, this is only a preferred arrangement and is not a limitation. The number of partitions 2 can also be other numbers, such as 3, 4, or other values. Those skilled in the art can set it according to the actual situation.

[0039] See next. Figure 2 and 3 ,like Figure 2 and 3As shown, each partition 2 has a gap with the inner bottom wall of the bag body 1, and multiple fluid chambers are directly or indirectly connected through the gaps. Specifically, the lower surface of each partition 2 has a first gap 3 formed with the inner bottom surface of the bag body 1. Each partition 2 has a first gap 3 below it. That is to say, a gap is formed between the partition 2 and the inner bottom wall of the bag body 1, which allows multiple fluid chambers to be directly or indirectly connected at the bottom of the liquid bag. The bottom of each fluid chamber can realize the mutual flow of fluid. At the same time, since the fluid outlet of the container is located at the bottom, after the fluid outlet 13 is connected to the fluid outlet, the fluid can be released from the bottom of the liquid bag. By forming a gap between the partition 2 and the inner bottom wall of the bag body 1, regardless of the amount of fluid in the liquid bag, it can effectively prevent shaking and facilitate the discharge of fluid, without requiring any modification to the structure of the container.

[0040] Furthermore, each partition 2 has a gap with the inner top wall of the bag body 1, and multiple fluid chambers are directly or indirectly connected through the gaps. Specifically, the upper surface of each partition 2 has a second gap 4 between it and the inner top surface of the bag body 1. Each partition 2 has a second gap 4 above it. When the liquid bag is loaded with fluid, it is generally not completely filled. Therefore, it is not necessary to connect the partition 2 to the top of the bag body 1. This can save materials and reduce the connection between the partition 2 and the top of the bag body, thus reducing the connection process.

[0041] like Figure 3 As shown, the front side of the partition 2 is connected to the front inner wall of the bag body 1, and the rear side of the partition 2 is connected to the rear inner wall of the bag body 1. When fluid is stored inside the bag body 1, the front side of the bag body 1 will be close to the front inner wall of the container (not shown in the figure), and the rear inner wall of the bag body 1 will be close to the rear inner wall of the container. At this time, the distance between the front inner wall and the rear inner wall of the bag body 1 reaches the preset maximum distance, and the partition 2 will also be stretched to become a partition that can block the flow of fluid, which can effectively prevent the fluid from sloshing.

[0042] It should be noted that although in this preferred embodiment, gaps are formed between the partition 2 and the inner bottom wall and inner top wall of the bag body 1, this is not limiting. In other embodiments, each partition 2 only forms a gap with the inner side wall of the bag body 1, and multiple fluid chambers are directly or indirectly connected through the gaps; in other embodiments, each partition 2 only forms a gap with the inner bottom wall of the bag body 1, and multiple fluid chambers are directly or indirectly connected through the gaps; in other embodiments, each partition 2 forms a gap with both the inner side wall and inner side wall of the bag body 1. A gap is formed between the partition 2 and the inner bottom wall of the bag body 1, and multiple fluid chambers are directly or indirectly connected through the gaps. In other embodiments, each partition 2 forms a gap with at least one of the inner bottom wall, inner side wall, and inner top wall of the bag body 1, and multiple fluid chambers are directly or indirectly connected through the gaps. The gaps formed between the multiple partitions 2 and the inner wall of the bag body 1 may be located on the same side of the partition 2, or the gaps formed between the multiple partitions 2 and the inner wall of the bag body 1 may be located on different sides of the partition 2. For example, in the first method: Figure 1 In the indicated orientation, the first partition 21 forms a gap only with the front side wall, the second partition 22 forms a gap only with the rear inner wall, the third partition 23 forms a gap only with the upper inner wall, the fourth partition 24 forms a gap only with the lower inner wall, and the fifth partition 25 forms a gap only with the lower inner wall; In the second orientation, the first partition 21 forms a gap only with the lower wall, the second partition 22 forms a gap only with the upper inner wall, the third partition 23 forms a gap only with the front inner wall, the fourth partition 24 forms a gap only with the rear inner wall, and the fifth partition 25 forms a gap only with the lower inner wall; those skilled in the art can set the gap positions themselves according to actual conditions. Changes in the gap positions do not deviate from the basic principles of this utility model and will fall within the protection scope of this utility model.

[0043] See Figure 1 As shown, the detailed explanation of the inner sidewall of the bag body 1 of this utility model is as follows: If multiple partitions 2 are arranged side by side (the partitions 2 can prevent fluid from swaying left and right), then the inner sidewall refers to the front inner wall and the rear inner wall of the bag body 1. The gap between the bag body 1 and the inner sidewall can mean that it only forms a gap with the front inner wall, or it can mean that it only forms a gap with the rear inner wall, or it can mean that it forms a gap with both the front inner wall and the rear inner wall. If multiple partitions 2 are arranged front and back side by side (the partitions 2 can prevent fluid from swaying back and forth), then the inner sidewall refers to the left inner wall and the right inner wall of the bag body 1. The gap between the bag body 1 and the inner sidewall can mean that it only forms a gap with the left inner wall, or it can mean that it only forms a gap with the right inner wall, or it can mean that it forms a gap with both the left inner wall and the right inner wall.

[0044] Further reading Figure 1As shown, when the partition 2 forms a gap with the inner side wall of the bag body 1, for example, when the partition 2 only forms a gap with the front inner wall of the bag body 1, the upper, lower, and rear sides of the partition 2 can be connected to the upper, lower, and rear inner walls of the bag body 1 respectively. At this time, the space on the front side of the bag body 1 is unobstructed from bottom to top, facilitating the flow of fluid. Similarly, if the partition 2 only forms a gap with the rear inner wall of the bag body 1, the upper, lower, and front sides of the partition 2 can be connected to the upper, lower, and front inner walls of the bag body 1 respectively. At this time, the space on the rear side of the bag body 1 is unobstructed from bottom to top, facilitating the flow of liquid.

[0045] See next. Figure 4 In another preferred embodiment of the liquid bag, a first gap 3 is formed between the partition 2 and the lower inner wall of the bag body 1, a second gap 4 is formed between the partition 2 and the upper inner wall of the bag body 1, a third gap 6 is formed between the partition 2 and the rear inner wall of the bag body 1, and a fourth gap 7 is formed between the partition 2 and the upper inner wall of the bag body 1. The front side of the partition 2 is connected to the front inner wall of the bag body 1 through multiple connectors 8, and the rear side of the partition 2 is connected to the rear inner wall of the bag body 1 through multiple connectors 8. Of course, this is not limiting. In other embodiments, the upper part of the partition 2 can be connected to the upper inner wall of the bag body through multiple connectors 8, and the lower part of the partition 2 can be connected to the lower inner wall of the bag body through multiple connectors 8. The connectors 8 are provided so that the partition 2 is connected to the opposite inner walls of the bag body 1, and gaps are formed around the partition 2 to facilitate the flow of fluid. When fluid is injected, it can be evenly distributed to each fluid chamber, and at the same time, it is convenient for the fluid to be discharged.

[0046] The connector 8 is preferably made of the same material as the partition 2, but it can also be a flexible connecting rope or other structures. Those skilled in the art can set it according to the actual situation.

[0047] In other embodiments, each partition 2 is provided with a notch, and multiple fluid chambers are sequentially connected through multiple notches. See also Figure 5 , Figure 5 for Figure 1 Horizontal projection diagram from left to right ( Figure 1 The notch structure is not shown on the partition 2 in the middle. The first partition piece 21 is provided with a first notch, which corresponds to the horizontal projection. Figure 5 The first notch projection 211 in the middle, the second notch is provided on the second partition piece 22, and the corresponding horizontal projection is as follows Figure 5 The second notch projection 221 in the middle, the third notch is provided on the third partition piece 23, and the corresponding horizontal projection is as follows Figure 5 The third notch projection 231 in the middle, the fourth notch is provided on the fourth partition piece 24, and the corresponding horizontal projection is as follows Figure 5The fourth notch projection 241 in the middle, the fifth notch is provided on the fifth partition piece 25, and the corresponding horizontal projection is as follows Figure 5 The fifth notch projection 251, the first notch projection 211, the second notch projection 221, the third notch projection 231, the fourth notch projection 241 and the fifth notch projection 251 are arranged vertically.

[0048] In other embodiments, such as Figure 6 As shown, the first notch projection 211, the second notch projection 221, the third notch projection 231, the fourth notch projection 241, and the fifth notch projection 251 are arranged in a front-to-back configuration. Figure 6 The projection of multiple notches in the image is set to left and right in the direction of the paper.

[0049] In another embodiment, such as Figure 7 As shown, the line segment connecting the center points of the first gap projection 211, the second gap projection 221, the third gap projection 231, the fourth gap projection 241, and the fifth gap projection 251 is an inclined line segment, that is, multiple gaps are set inclined downwards in sequence.

[0050] It should be noted that this utility model does not impose any restrictions on the number or distribution of notches. The lateral projections of multiple notches may overlap; the lateral projections of multiple notches may be distributed in an array; or multiple notches may be provided on each partition 2. Those skilled in the art can set them according to the actual situation.

[0051] See next. Figure 8 ,like Figure 8 As shown, the partition 2 is provided with an inflation part 202, and the inner wall of the bag body 1 is provided with a flexible ring 101. The inflation part 202 is inserted into the flexible ring 101. When the inflation part 202 is inflated, the partition 2 is connected to the inner wall of the bag body 1. Based on the above structural design, it is convenient to connect the partition 2 to the bag body 1. When the inflation part 202 is not inflated, it is in a contracted state and can be inserted into the flexible ring 101. When the inflation part 202 is inflated, it is in a bulging state and can achieve a stable connection with the flexible ring 101.

[0052] Furthermore, the inflation part 202 also includes a first limiting part 2021 and a second limiting part 2022. When the fluid impacts the partition 2 from right to left, the first limiting part 2021 and the second limiting part 2022 can prevent the inflation part 202 from coming out of the flexible ring 101, thereby improving the connection strength between the inflation part 202 and the flexible ring 101.

[0053] It should be noted that this utility model does not impose any limitations on the specific structure of the inflation part 202, which can be as follows: Figure 8The “T” shaped structure shown can also be an “L” shaped structure, that is, only a first limiting part 2021 or only a second limiting part 2022 is provided, or the first limiting part 2021 and the second limiting part 2022 can form a structure with a disc-shaped outer surface. Those skilled in the art can set it according to the actual situation.

[0054] Additionally, it should be noted that this utility model does not impose any restrictions on the specific connection method between the partition 2 and the inner wall of the bag body 1. It can be that one of the partition 2 and the inner wall of the bag body 1 is provided with a flexible ring 101, and the other of the partition 2 and the inner wall of the bag body 1 is provided with an inflation part 202 inserted into the flexible ring 101. When the inflation part 202 is inflated, the partition 2 is connected to the inner wall of the bag body 1. Alternatively, the partition 2 can be directly connected to the inner wall of the bag body 1 by adhesive bonding, sewing, heat sealing, ultrasonic welding, or high-frequency welding.

[0055] Preferably, a first inflation chamber 201 is formed within the partition 2, and a second inflation chamber 2023 is formed within the inflation part 202. The first inflation chamber 201 and the second inflation chamber 2023 are connected. The partition 2 is configured to be inflatable. After inflation, the partition 2 provides a certain supporting force to the inside of the liquid bag, keeping the liquid bag in a firm shape. This is crucial for the storage and transportation of the liquid bag, as it ensures that the liquid bag maintains a stable shape during loading and unloading, preventing fluid leakage or operational difficulties caused by shape changes. As the fluid inside the liquid bag gradually decreases, the bag body 1 may deform due to the loss of fluid support. If the deformation is too large, it will not only affect the aesthetics of the liquid bag but may also increase the risk of the bag body 1 being scratched or damaged. Inflation of the partition 2 can reduce the deformation of the bag body 1 to a certain extent, keeping the bag body 1 in a relatively stable shape. During transportation, the liquid bag may move due to bumps or vibrations. This movement may not only lead to fluid leakage but also cause additional wear and tear on the liquid bag. Inflating the partition 2 can reduce the movement of the bag 1 by increasing the internal rigidity of the bag 1, thereby reducing these risks.

[0056] By making the partition 2 inflatable, the liquid bag can be supported in its shape and the bag body can be supported. When the internal fluid is small, it can also reduce the deformation and movement of the bag body 1 to a certain extent, thereby reducing the risk of the bag body 1 being scratched or damaged.

[0057] In some other embodiments, the partition 2 does not include the inflation part 202. The partition 2 is configured to be inflatable and can be connected to the bag body 1 after being fully inflated.

[0058] Continue reading Figure 8The first limiting part 2021 is located below the second limiting part 2022, and is the one furthest from the inner wall of the bag body 1. An inflation valve 5 is provided on the first limiting part 2021, with the valve opening facing downwards. Positioning the inflation valve 5 on the side of the inflation part 202 furthest from the inner wall of the bag body 1 prevents the inflation valve 5 from tearing the bag body 1. However, this is not a limitation; the inflation valve 5 can also be located in the area of ​​the partition 2 furthest from the inner wall of the bag body 1, such as... Figure 9 As shown, an inflation valve 5 is provided in the middle area of ​​the partition 2, and the inflation valve port is also located in the middle area.

[0059] Furthermore, bag body 1 is composed of multiple bag panels spliced ​​together, and sealed using laser welding or ultrasonic welding after splicing. Of course, this is not a limitation; bag body 1 can also be integrally molded. The liquid bag also includes an outer bag (not shown in the figure), which wraps around and covers bag body 1. By wrapping and covering bag body 1 with the outer bag, leakage caused by wear and tear during transportation is effectively prevented. This design not only increases the overall sealing performance of the liquid bag, but the outer bag also provides an extra layer of protection for the inner bag (bag body 1), enhancing the overall strength of bag body 1. This is especially important for liquid bags that need to withstand high pressure or weight.

[0060] The materials of the bag body 1 and the partition 2 can be the same or different. The materials can be PE (polyethylene), PP (polypropylene), PVC (polyvinyl chloride) and TPU (thermoplastic polyurethane), or other film or sheet materials that can be molded into bags. The materials are soft and deformable, and the shape depends on the container.

[0061] It should be noted that, although the appendix shown in this utility model... Figure 1 The shape of the bag body 1 is a cuboid, but this is not a limitation. It can also be a pillow shape or other shapes. Those skilled in the art can set it according to the actual situation.

[0062] In other embodiments, multiple partitions 2 divide the fluid storage space 11 into multiple non-interconnected fluid chambers, each fluid chamber having a fluid inlet 12 and a fluid outlet 13.

[0063] It should be noted that this utility model does not impose any restrictions on the specific location of the fluid outlet 13 of the fluid inlet 12. The fluid inlet 12 can be located in any area on the upper surface of the bag body 1, or it can be located in the area from the middle upwards on the side of the bag body 1. The fluid outlet 13 can be located in any area on the lower surface of the bag body 1, or it can be located in the bottom area on the side of the bag body 1. Those skilled in the art can set it according to the actual situation.

[0064] The fluid used in this invention is preferably a liquid, but it can also be other fluids, such as particulate fluids.

[0065] It should be noted that although the liquid bag is depicted as a cuboid in the attached diagram, this is merely for ease of illustration and description. In actual use, the liquid bag is typically placed inside a container or other rigid container, thus constraining its shape to a cuboid. Without the constraint of an external rigid container, the liquid bag, being a flexible material, will usually have a rounded shape after being filled with fluid.
