Description

Technical Field

[0001] This utility model relates to the field of liquid material transportation, specifically providing a container and its liquid bag for storing and transporting liquid materials. Background Technology

[0002] In the field of liquid material (hereinafter referred to as liquid cargo) container transportation, liquid bags, as a type of flexible liquid storage container, are widely used in sea, rail, and road transportation. By being fixed inside a container, they utilize their flexibility to carry liquid materials (such as food-grade liquids and chemicals), significantly reducing storage and transportation costs compared to traditional rigid container transportation (such as liquid tanks).

[0003] Existing liquid material containers typically have a liquid bag set in the center of the container. The liquid bag is adapted to the container size (e.g., 20 feet / 40 feet). The central arrangement of the liquid bag can simplify the installation process, ensure that the front and rear fixing straps are symmetrically stressed, avoid local stress concentration caused by off-center loading, and the loading and unloading of liquid can be completed in one go. The operation is simple and the loading and unloading efficiency is high. However, there are also the following problems: (1) After the liquid is injected, the liquid tends to diffuse outward under the action of gravity, causing the liquid bag to be deformed into a "waist-shaped" shape. The side wall of the container is a single layer of corrugated steel plate, and the bending stiffness is much lower than that of the front and rear frame, which makes the side wall of the container easy to bulge outward and deform. (2) The traditional liquid bag design focuses on static working conditions (such as storage or short-distance transportation) and does not fully consider the liquid sloshing problem in dynamic scenarios such as sea and rail. In maritime environments, cargo ships carrying containers must withstand the three-dimensional combined impact of waves. Traditional liquid bags are only constrained by front and rear end fixing straps and bottom anchor points of the container, causing the surge energy to be directly transferred to the side wall of the container through the liquid medium, which significantly increases the risk of fatigue damage to the container.

[0004] Therefore, a new type of container is urgently needed to solve the above problems. Utility Model Content

[0005] In order to solve the aforementioned technical problems in the prior art, that is, at least to solve the problem of easy deformation of the side walls of existing containers.

[0006] For this purpose, the present invention provides a container for storing and transporting liquids, the container comprising:

[0007] The enclosure, whose interior forms storage space;

[0008] Multiple independent liquid bags are arranged in the storage space along at least one direction of the housing;

[0009] A protective component is disposed between two adjacent liquid bags;

[0010] Two protective components are provided between two adjacent liquid bags, and each protective component pulls the liquid bag toward the corresponding liquid bag.

[0011] In some feasible embodiments of the container used for storing and transporting liquids described above, the protective member is a flexible component, and in the case of liquid filling the liquid bag, the protective member at least covers a portion of the liquid bag.

[0012] In some feasible embodiments of the container used for storing and transporting liquids described above, the protective component is detachably connected to the inner wall of the container.

[0013] In some feasible embodiments of the container used for storing and transporting liquid materials, the protective component includes a component body and ropes disposed at the four corners of the component body, the component body being attached to the inner wall of the container via the ropes.

[0014] In some feasible embodiments of the container described above for storing and transporting liquids, at least a portion of the protective member is pressed against the bottom of the liquid bag.

[0015] In some feasible embodiments of the container used for storing and transporting liquids described above, the container further includes:

[0016] A reinforcing member is provided on the inner side wall of the housing.

[0017] In some feasible embodiments of the container described above for storing and transporting liquids, the reinforcing member is arranged vertically or laterally near the center of at least one of the liquid bags.

[0018] In some feasible embodiments of the container for storing and transporting liquids described above, the reinforcing member is provided at least near the middle of the liquid bag along the length of the container body.

[0019] In some feasible embodiments of the container used for storing and transporting liquids described above, the container further includes:

[0020] The liner is inserted between the liquid bag and the inner wall of the box.

[0021] In some feasible embodiments of the container used for storing and transporting liquids described above, the container body is a cuboid, and the plurality of liquid bags includes two liquid bags arranged along the length direction of the container body.

[0022] In some feasible embodiments of the container used for storing and transporting liquids described above, the container body is a cube, and the plurality of liquid bags includes four liquid bags respectively arranged along the length and width directions of the container body.

[0023] This utility model provides a container for storing and transporting liquid materials. By disassembling a single integral liquid bag into multiple independent liquid bags arranged along the length of the container and separating them with protective components, a multi-chamber structure is formed. This shortens the length of a single liquid bag, disperses liquid pressure, significantly reduces the unsupported span of the liquid bag, and reduces the outward bulge in the middle, thereby reducing the force on the side walls of the container and effectively preventing container deformation. Furthermore, the protective components prevent liquid sloshing, reducing the impact force of the unit weight and thus reducing the impact of surges on the front, rear, and side walls of the container, effectively preventing container deformation. In addition, by placing two protective components between two adjacent liquid bags, each protective component pulls the liquid bag towards the corresponding liquid bag, providing auxiliary shaping of the liquid bag and enabling each protective component to provide shaping for the filled liquid bag. Moreover, by independently setting protective components, compared with the existing technology of directly attaching the liquid bag itself to the container with ropes, the protective components not only provide additional support and auxiliary shaping but also do not affect the structural strength of the liquid bag itself, and also simplify the production process.

[0024] Furthermore, by incorporating reinforcing components, the structural strength of the side walls can be enhanced to further resist the impact of liquid within the liquid bag. The addition of an inner liner can further disperse liquid pressure while simultaneously increasing the strength of the box's side walls.

[0025] In a second aspect, the present invention also provides a liquid bag, which is applicable to the container for storing and transporting liquid materials described in any of the foregoing technical solutions. Attached Figure Description

[0034] Furthermore, in the description of this utility model, "not shown" means not illustrated in the drawings, and "not marked" means that the relevant structure is shown in the drawings but not marked.

[0035] The container for storing and transporting liquid materials provided by this utility model will be described below with reference to the accompanying drawings. It should be noted that the liquid materials here include conventional liquids, as well as fluids, solid-liquid mixtures in a fluid state, etc.

[0036] The container provided in this embodiment of the utility model includes:

[0037] Container 1, whose interior forms storage space. Specifically, this embodiment uses a 20-foot container as an example. A shipping container is a standardized, large-scale cargo transportation unit, typically made of high-strength, corrosion-resistant steel or aluminum, characterized by its sturdiness, durability, good sealing, and ease of stacking. Its design follows internationally unified dimensional standards, facilitating rapid loading, unloading, and transshipment between various modes of transport (such as ships and trains). Figure 1As shown, the box includes a bottom wall (not shown), a top wall (not shown), left and right side walls (not shown), a rear side wall (not shown), and a door-shaped front side wall (not shown). For ease of observation, some structures of the left and right side walls have been omitted.

[0038] Multiple independent liquid bags. Specifically, the container 1 contains multiple independent liquid bags, each arranged within the storage space of the container along at least one direction. For example... Figure 1 As shown in the illustration, this embodiment uses two independent liquid bags: a first liquid bag 2 and a second liquid bag 3, both made of the same material and of the same size. Taking the first liquid bag 2 as an example, its bag body typically includes a PP woven layer and a PE inner film layer located inside the PP woven layer, where PP refers to polypropylene and PE refers to polyethylene. It should be noted that the arrangement of the liquid bags is not limited to one direction, nor is it limited to two liquid bags; multiple liquid bags can be arranged along one direction, or more than two liquid bags can be arranged along two directions.

[0039] For each liquid bag, loading and unloading methods can be adopted, such as top loading / unloading, bottom loading / unloading, or top loading / unloading. Specifically, taking the first liquid bag 2 as an example, it has only one loading / unloading port, located at the top of the liquid bag near the second liquid bag, for convenient filling. A valve 21 is provided at the loading / unloading port to control its opening and closing. In addition to the liquid filling port at the top, the second liquid bag 3 also has a discharge port at the bottom of its side wall, and a discharge valve is provided at the discharge port.

[0040] The container 1 also includes protective components positioned between two adjacent liquid bags to enhance their stability during transport, thereby preventing significant impact on the container's side walls and effectively protecting the container from deformation. Specifically, in this embodiment, the protective components include a first protective component 4 and a second protective component 5, both of which are flexible parts. Figure 1 and Figure 2 In the case of liquid bag injection, the protective component must at least cover a portion of the liquid bag. For example, taking the first protective component 4 as an example, it can be made of high-strength nylon cloth, cotton cloth, canvas, or other materials. The shape of the first protective component 4 can be flat or irregularly shaped to form a wrapping structure around the injected liquid bag, such as an irregularly shaped structure formed by splicing multiple sheets, or an open bag-like structure. To enhance the protective capability of the protective component during the protection process, during the installation stage before injection, it must be ensured that at least a portion of the protective component is pressed against the bottom of the liquid bag.

[0041] In this embodiment, two protective members are provided between two adjacent liquid bags, and each protective member pulls the liquid bag toward the corresponding liquid bag. Figure 1 and Figure 2As shown, the first protective component 4 is mainly used to protect the first liquid bag 2 and prevent the first liquid bag 2 from moving towards the second liquid bag 3 due to inertia, gravity, etc.; the second protective component 5 is mainly used to protect the second liquid bag 3 and prevent the second liquid bag 3 from moving towards the first liquid bag 2 due to inertia, gravity, etc.

[0042] Alternatively, the protective component can also be a rigid component, such as a wooden board or steel plate, which, by fixing it to the box, can restrict the movement of the liquid bag along the length or width of the box. Furthermore, the protective component can also be a combination of flexible and rigid components, such as a combination of the steel plate in the above example and the first / second protective component in the above example, such as adding a steel plate or wooden board between the first and second protective components.

[0043] To facilitate the installation of the protective components, this embodiment uses a hook-and-loop method to attach the four corners of the protective components to the inner wall of the enclosure. Specifically, as shown... Figure 1 As shown, taking the first protective component 4 as an example, the first protective component 4 includes a component body (not shown) and ropes 41 disposed at the four corners of the component body. The component body is attached to the inner wall of the box via the ropes 41. The inner wall of the box 1 is provided with hooks, and the ropes 41 can be directly attached to the hooks.

[0044] Alternatively, the protective component can be connected to the inner wall of the enclosure using other detachable connection methods. For example, it can be connected by plugging or snapping. To prevent sharp hooks from damaging the liquid bag, one of the male and female clips can be installed on the side wall of the enclosure, with the other clip connected to the four corners of the protective component, thus securing the protective component.

[0045] To further enhance the strength of the box's side walls, a reinforcing member 6 can be installed inside the box 1. The reinforcing member 6 is located on the inner side wall of the box. The reinforcing member 6 is positioned vertically or horizontally near the center of at least one liquid bag. For example, such as... Figure 1 As shown in the diagram, the reinforcing member 6 in this embodiment is a vertically extending rod, such as a hollow square steel bar or steel pipe. Alternatively, the reinforcing member 6 can also be a steel plate or corrugated plate with a certain width. The reinforcing member 6 can be fixed to the housing 1 by welding, fastener connection, or other methods.

[0046] Alternatively, it can be configured as a laterally extending rod, such as welding at least one crossbar at the middle position of the left and right side walls of the box 1.

[0047] Regarding the number of reinforcing members 6, in the length direction of the housing 1, it is sufficient to ensure that the reinforcing members 6 are at least located near the middle of the liquid bag. In this invention, the number of reinforcing members is not limited. This is equivalent to ensuring that strong restraint is provided at least at the location where the liquid bag has the greatest tendency to bulge outward.

[0048] Furthermore, to protect the liquid bag from damage by the rigid structure inside the box and to prevent leakage, an inner lining is installed inside the box 1, which extends between the liquid bag and the inner wall of the box. Specifically, such as... Figure 2 As shown, the inner lining can be made of corrugated cardboard, nylon fabric, canvas, etc., with corrugated cardboard being preferred. The inner lining includes a bottom lining and side walls. The bottom lining extends between the bottom of the liquid bag and the bottom wall of the container, while the side walls extend between the sides of the liquid bag and the inner wall of the container. The height of the side walls is at least higher than the midpoint of the container's height to provide better protection. It is understood that the inner lining may be positioned to avoid interference with the installation of the protective components.

[0049] The specific loading and unloading process is as follows: First, lay an inner lining inside the container 1, such as corrugated cardboard, with a portion of the side wall reinforcement 6 of the corrugated cardboard. Then, simultaneously install the first protective component 4 and the first liquid bag 2. Connect the bottom two corners of the first protective component 4 to hooks on the side wall of the container using ropes 41. Next, lay the first liquid bag 2, ensuring that a portion of the first protective component 4 is pressed under the first liquid bag 2. Then, connect the top two corners of the first protective component 4 to the side wall of the container using ropes 41, ensuring that the valve 21 of the first liquid bag 2 remains in an operable position. Inject liquid into the first liquid bag 2, and then tighten the valve 21. Next, install the second protective component 5 and the second liquid bag 3, following the same steps as the installation of the first protective component 4 and the first liquid bag 2. Inject liquid into the second liquid bag 3, and then tighten the discharge valve. This basically completes the entire installation and filling process.

[0050] Alternatively, the first liquid bag 2, the second liquid bag 3, the first protective component 4, and the second protective component 5 can be installed before liquid filling, which can achieve streamlined operation and improve efficiency.

[0051] The container for storing and transporting liquids provided by this utility model disassembles a single integral liquid bag into multiple independent liquid bags arranged along the length of the container body, and separates them with protective components to form a multi-chamber structure. This shortens the length of a single liquid bag, disperses the liquid pressure, significantly reduces the unsupported span of the liquid bag, and reduces the outward bulge in the middle, thereby reducing the force on the side walls of the container body and effectively preventing container deformation. In addition, the protective components block the linkage sloshing of the liquid, reducing the impact force of the unit weight, thereby reducing the impact of surges on the front, rear, and side walls of the container and effectively preventing container deformation.

[0052] The above embodiments are illustrated using a rectangular container as an example, but are not limited to containers with a rectangular structure. The container can also be a cube structure, in which case four liquid bags can be arranged in an array along the length and width of the container.

[0053] Furthermore, this utility model also provides a liquid bag, for example, the first liquid bag and the second liquid bag described above. It is understood that this utility model does not limit the specific shape or size of the liquid bag, as long as it is suitable for the aforementioned container and can serve as a liquid bag in the container to provide space for liquid materials.

[0054] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
