Description

Technical Field

[0001] This utility model generally relates to the field of storage and transportation technology. More specifically, this utility model relates to a material packaging barrel. Background Technology

[0002] In industrial production processes such as lithium battery manufacturing, powder materials, such as anode materials, are often key components. These powdered materials, due to their large specific surface area, are highly susceptible to chemical reactions upon contact with air during transportation or storage. These reactions can range from localized heating to spontaneous combustion, and under certain conditions, even explosions. The hazards posed by this series of dangerous processes are significant, causing not only substantial waste of raw materials and economic losses, but also direct threats to human life and severe environmental pollution. The spontaneous combustion of powder materials is primarily due to their reactive chemical properties, making them prone to ignition under suitable temperature, humidity, and specific oxygen concentrations. Furthermore, bumps during transportation, friction during handling, and collisions between material particles can generate electrostatic sparks, which can then ignite the powder. Given the high risks involved in the transportation and storage of powder materials, implementing comprehensive protective measures and stable sealing conditions are crucial to ensuring safety. However, the powder material storage and transportation devices commonly used in the current industrial field have significant deficiencies in sealing performance. Even with these devices, it is still difficult to completely eliminate potential safety hazards during the storage and transportation of powder materials.

[0003] In view of this, there is an urgent need to provide a material packaging container to improve the sealing effect of powder materials. Utility Model Content

[0026] In view of this, the present invention provides a material packaging barrel, which, by setting a barrel body and a barrel lid that are relatively interlocked, and by using a locking component to interlock the barrel body and the barrel lid, seals the inner lining bag inside, thereby enhancing the sealing effect of the sealed barrel during transportation.

[0027] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] See Figure 1 and Figure 2 , Figure 1 Exemplary cross-sectional views of material packaging drums according to some embodiments of the present invention are shown. Figure 2 It shows Figure 1 A partially enlarged schematic diagram of section A. The material packaging drum includes a drum body 10 and a drum lid 30 that are interlocked, a locking assembly 40 for locking the drum body 10 and the drum lid 30, and an inner liner bag 20 disposed within the inner cavity 110 of the drum body 10 for containing powdered materials such as negative electrode materials. The drum body 10 has a hollow inner cavity 110 and an upwardly opening 120. The inner liner bag 20 is disposed within the inner cavity 110 and has a sealable receiving cavity. A sealing element 31 is provided on the outer periphery of the drum lid 30. The drum lid 30 is detachably fastened to the opening 120, and the sealing element 31 contacts the edge of the opening 120 to seal the inner liner bag 20. The locking assembly 40 releasably locks the drum body 10 and the drum lid 30.

[0029] Specifically, the barrel 10 is a hollow barrel with one open side, designed to seal and protect the materials to be transported inside. It is made of a rigid material such as resin or metal. One end of the barrel 10 is open along its axial direction, forming an opening 120, through which the materials to be stored and corresponding packaging or sealing materials can be loaded into the barrel 10. The edge of the barrel 10 near the opening 120 is used to abut against the lid 30, and together with the lid 30, seals its inner cavity 110. The edge of the barrel 10 at the opening 120 also has a protruding circular outer edge. This protruding circular outer edge has a larger cross-sectional area than the barrel wall and a larger contact area with the lid 30, which improves both the overall strength of the barrel 10 and the sealing effect after it is engaged with the lid 30.

[0030] The lid 30 can be made of the same material as the barrel body 10. It abuts against the barrel body 10 along the axial direction and simultaneously covers and seals the inner cavity 110 of the barrel body 10. An annular sealing element 31 is provided on the edge of the lid 30 that abuts against the barrel body 10. This sealing element 31 is made of a material with a certain elasticity, such as rubber. After the lid 30 and barrel body 10 are fastened together, the sealing element 31 can be deformed under pressure and seal the gap between them, thereby improving the sealing effect. The locking assembly 40 connects to both the lid 30 and the barrel body 10 to lock the barrel body 10 relative to the lid 30, maintaining the sealed state inside the barrel body 10 during storage or transportation. The inner cavity 110 of the barrel body 10 is provided with an inner liner bag 20. The receiving cavity inside the inner liner bag 20 is used to directly hold the material to be stored. The combination of the barrel body 10 and the barrel lid 30 achieves a primary seal for the material, while the inner liner bag 20 itself forms a secondary seal for the material, thereby significantly enhancing the sealing effect of the material during storage or transportation.

[0031] See Figure 2 The locking component 40 is disposed on the outside of the opening 120. Specifically, the locking component 40 is disposed on the radially outer side of the opening 120 adjacent to the barrel lid 30, and is connected to both the barrel body 10 and the barrel lid 30. By placing the locking component 40 near the opening 120, the distance between the operating part and the actuating part of the locking component 40 can be reduced, and the size of the component used for direct pressing can be reduced. This allows for a more stable locking effect with a smaller locking component 40, resulting in a more compact overall structure and lower production costs.

[0032] In this embodiment, the locking assembly 40 includes a locking seat 41 fixedly disposed on the outside of the opening 120, and a latch 42 rotatably connected to the barrel body 10. The latch 42 can rotate relative to the barrel body 10 to abut against the locking seat 41 on one side and lock against the edge of the barrel lid 30 on the other side, and can also rotate relative to the barrel body 10 to unlock from the barrel lid 30. The locking seat 41 is used to limit one side of the latch 42, while the other side of the latch 42 can lock to the barrel lid 30. The locking is formed by the simultaneous connection of the latch 42, the locking seat 41, and the barrel lid 30. The latch 42 engages or abuts against the locking seat 41 and the barrel lid 30 respectively by means of its own elastic deformation. Thus, the locking assembly 40 improves the sealing stability between the barrel lid 30 and the barrel body 10 with a simple structure.

[0033] The latch 42 comprises a curved locking hook 421 and a hinge 422 for hingedly connecting the locking hook 421 to the barrel body 10. The hinge 422 is fixedly connected to the radially outer side of the barrel body 10, and the middle part of the locking hook 421 is hinged to the hinge 422, allowing both ends of the locking hook 421 to rotate relative to the barrel body 10 around the hinge 422. The side of the locking hook 421 closest to the opening 120 of the barrel body 10 bends towards the opening 120 and can rotate to abut against the lid 30, the edge of which is provided with a flange that matches the shape of the curved portion of the locking hook 421. The side of the locking hook 421 furthest from the opening 120 extends to the locking seat 41. The locking seat 41 is fixedly disposed on the outer side of the barrel wall of the barrel body 10 and has a locking opening 410 therein through which a portion of the locking hook 421 can pass and swing. The locking opening 410 is aligned with the axial direction of the barrel body 10 and is formed by multiple components enclosing the locking seat 41, or by a slot formed in the locking seat 41 which is integrally formed. When the locking hook 421 swings within the locking opening 410 on the side opposite to the opening 120 of the barrel body 10, the locking opening 410 can guide and limit the locking hook 421, so that when the locking hook 421 moves to a position that is locked relative to the barrel lid 30, it can be limited by the abutment of the inner wall of the locking opening 410.

[0034] In addition, see also Figure 2 and Figure 3 , Figure 3 A partially enlarged schematic diagram of a material packaging barrel according to some embodiments of the present invention is shown, wherein the locking hook 421 is pressed down and the barrel lid 30 is unlocked.

[0035] In this embodiment, the locking assembly 40 further includes an elastic element 43, which is disposed between the side of the locking hook 421 facing away from the opening 120 of the bucket body 10 and the outer wall of the bucket body 10, so that the locking hook 421 receives a continuous elastic pushing force to keep it locked to the bucket lid 30. When the user presses the side of the locking hook 421 facing away from the opening 120 relative to the bucket body 10, the elastic force of the elastic element 43 can be overcome, causing the locking hook 421 to disengage from the bucket lid 30. Those skilled in the art will understand that although the elastic element 43 is formed as a compression spring in this embodiment, in some embodiments not shown, the elastic element 43 can be other forms such as a torsion spring.

[0036] The use of material packaging drums includes filling, sealing, and unsealing procedures. During filling, the drum body 10 and lid 30 are separated, the opening 120 of the drum body 10 is open, and the inner liner bag 20 is placed in the inner cavity 110 of the drum body 10. The user first adds the powder material to be stored into the inner liner bag 20, and fills the inner liner bag 20 with protective gas according to filling requirements, and seals the opening of the inner liner bag 20 with equipment such as an air blower. Further, in the sealing procedure, the user fastens the lid 30 to the drum body 10, so that the lid 30 covers the opening 120, and the sealing element 31 of the lid 30 abuts against the edge of the opening 120 of the drum body 10. At the same time, the locking component 40 locks the drum body 10 and lid 30 relative to each other to maintain the sealed state inside the drum. After the material packaging drum is stored and transported to the target equipment, the unsealing procedure can be carried out. Here, the user unlocks the locking component 40, thereby separating the lid 30 from the body 10, allowing the user to open the inner bag 20 and remove the powder material.

[0037] See you again Figure 1 and Figure 2 In this embodiment, the barrel 10 is a stainless steel barrel with a diameter of 59 cm and a height of 90 cm, and the barrel lid 30 is a stainless steel barrel lid with a diameter of 60 cm. By setting the barrel 10 to have a diameter of 59 cm and a height of 90 cm, the capacity of the barrel 10 is ensured while the total weight of the barrel 10 after being filled is controlled to a size that is easy to move. It also reduces the accumulation of static electricity caused by friction between powder particles when the powder content in the barrel is too large, thus improving the safety during storage and transportation. By setting the diameter of the barrel lid 30 to 60 cm, it is ensured that the outer edge of the barrel lid 30 completely covers the opening 120 of the barrel 10, thereby further improving the sealing effect with the help of the locking component 40.

[0038] The inner liner bag 20 is made of a PE film with a thickness of 0.08 mm. Therefore, based on the material properties of the PE film, the inner liner bag 20 ensures sufficient strength while improving sealing performance and reducing the chemical or physical impact of the material of the inner liner bag 20 on the material inside the drum, thus maintaining the stability of the material's properties. Furthermore, the material packaging drum also includes an inner packaging bag 50, which is disposed outside the inner liner bag 20. The inner packaging bag 50 is used to surround the inner liner bag 20, enhancing its strength and reducing the risk of wear or even leakage caused by direct friction with other components during transportation or filling. The material of the inner packaging bag 50 can be a woven bag, etc. In this embodiment, the material of the inner packaging bag 50 is a coated PP woven fabric, which provides protection for the inner liner bag 20 due to its good structural strength.

[0039] The inner packaging bag 50 and the inner liner bag 20 are independently arranged and are not fixed relative to the barrel body 10. However, in some embodiments not shown, the inner packaging bag 50 can be fixed relative to the inner liner bag 20 by means of adhesive bonding or other methods to reduce the probability of misalignment between the inner liner bag 20 and the inner packaging bag 50 during transportation. Alternatively, in some other embodiments, the inner packaging bag 50 can be fixed relative to the barrel body 10 by means of adhesive bonding or other methods to reduce the relative friction between the inner packaging bag 50 and the barrel body 10 and improve the service life of the inner packaging bag 50.

[0040] In addition, the inner packaging bag 50 also includes a handle 51, which is fixedly disposed on the outside of the inner packaging bag 50 and extends toward the opening 120 of the barrel body 10. When opening the barrel and handling materials, the handle 51 can be used with equipment such as a hoist to lift the entire inner packaging bag 50, facilitating the transportation of materials. With the help of the handle 51 fixed to the inner packaging bag 50, the force during hoisting will not be applied to the inner liner bag 20, thereby reducing the risk of the inner liner bag 20 tearing due to handling force.

[0041] See Figure 4 , Figure 4 A partially enlarged schematic diagram of a material packaging drum according to some embodiments of the present invention is shown. In this embodiment, the locking assembly 60 includes a locking seat 61 fixedly disposed on the edge of the drum lid 30, and a latch 62 rotatably connected to the drum lid 30. The latch 62 can rotate relative to the drum lid 30 to abut against the locking seat 61 on one side and lock against the edge of the opening 120 of the drum body 10 on the other side, and can rotate relative to the drum lid 30 to unlock from the drum body 10. Specifically, the locking seat 61 is fixedly disposed on the drum lid 30, and the latch 62 includes a locking hook 621 and a hinge member 622 for hingedly connecting the locking hook 621 to the edge of the drum lid 30. The portion of the locking hook 621 facing the drum body 10 is configured to bend towards the drum body 10 and abut against a radially outwardly protruding flange portion at the opening 120 of the drum body 10, thereby locking the drum lid 30 to the drum body 10 in the axial direction of the drum body 10. In addition, the locking assembly 60 also includes an elastic element 63, which is disposed between the side of the locking hook 621 away from the barrel body 10 and the barrel lid 30, so as to provide a continuous elastic thrust to the locking hook 621, so that the barrel lid 30 and the barrel body 10 are locked together.

[0042] Those skilled in the art will understand that although the above description describes a structure in which the locking component is configured with a rotatable latch and a locking seat for securing the latch, the present invention does not limit the specific form of the locking component. In some embodiments not shown, the locking component may include a movable ring disposed on the bucket body and a hook disposed on the bucket lid, and the locking of the bucket body and the bucket lid is achieved by means of the engagement between the movable ring and the hook. Alternatively, in other embodiments, the locking component is a deformable hook fixed to or integrally formed with the bucket lid, which can directly engage with the flange or latch at the opening of the bucket body when the bucket lid is fastened relative to the bucket body.

[0043] The material packaging barrel according to the present invention has a barrel body and a barrel lid that are relatively interlocked, and the sealing effect inside the barrel is enhanced by locking components and sealing elements. At the same time, the material is sealed again inside the barrel by an inner liner bag. This can significantly improve the safety of powder materials such as negative electrode materials during transportation or storage. It is also easy to operate, has a reliable structure, and is suitable for large-scale production scenarios.

[0044] While various embodiments of the present invention have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of the present invention. It should be understood that various alternatives to the embodiments of the present invention described herein may be employed in the practice of the present invention. The appended claims are intended to define the scope of protection of the present invention and therefore cover equivalents or alternatives within the scope of these claims.
