Description

Technical Field

[0001] This utility model relates to the field of container bag reinforcement technology, and in particular to a corrosion-resistant reinforced container bag. Background Technology

[0002] FIBCs, also known as bulk bags or jumbo bags, are flexible transport packaging containers made primarily of synthetic fiber fabrics such as polypropylene and polyethylene. Their structure typically includes lifting straps (for lifting), an inlet, and an outlet (often zippered or tied with rope), with some featuring reinforcing ribs to enhance load-bearing capacity.

[0003] FIBCs (Flexible Intermediate Bulk Containers) are mainly used for transporting bulk materials such as grains, chemical raw materials, ores, cement, and feed. Their load-bearing capacity is generally 0.5 to 3 tons, with special specifications reaching over 5 tons. They feature good flexibility, foldable empty bags (saving storage and transportation space), moisture and dust protection (some are coated or composite treated), and resistance to acid and alkali corrosion (depending on the material). They are widely used in industry, agriculture, and logistics, especially suitable for mechanized loading and unloading, long-distance transportation, and warehousing of bulk goods. They can significantly improve operational efficiency, reduce labor costs, and some are reusable, aligning with the trend of green packaging.

[0004] Currently, the single-layer air bladders on the sides of FIBCs (Flexible Intermediate Bulk Containers) suffer from a simple structure, insufficient stability after inflation, and limited fit with the bag body. When materials are loaded, the radial stress generated by the material compression on the side cannot be effectively dispersed by the single-layer air bladder, causing it to bulge outwards and deform excessively. This problem directly leads to increased space occupation and reduced loading capacity during transportation. When stacked, the uneven stress on the protruding parts makes it easy to tip over, and it is difficult to arrange them tightly during storage, resulting in wasted space. At the same time, the protruding side is prone to damage from friction and collision with the outside, shortening its service life. Furthermore, the center of gravity shifts during lifting and handling, affecting operational safety, resulting in poor overall performance. Utility Model Content

[0005] The main objective of this invention is to provide a corrosion-resistant and reinforced container bag, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A corrosion-resistant reinforced container bag includes a container bag body, a bag opening, and reinforcing drawstrings. The bag opening is located at the upper center of the container bag body, and four reinforcing drawstrings are connected to the four upper corners of the container bag body. The outer end of the container bag is fitted with a corrosion-resistant reinforcement mechanism, which provides support and reinforcement to the outer end of the container bag. The corrosion-resistant reinforcement mechanism includes vertical corrosion-resistant airbags, lateral corrosion-resistant airbags, and inflation ports. Two vertical corrosion-resistant airbags are distributed at the four corners of the container bag. The upper and lower ends of the vertical corrosion-resistant airbags are respectively connected to a second lateral corrosion-resistant airbag and a first lateral corrosion-resistant airbag. The vertical corrosion-resistant airbags, the first lateral corrosion-resistant airbags, and the second lateral corrosion-resistant airbags are connected by bent tube corrosion-resistant airbags to form a rectangular frame-type corrosion-resistant airbag. The side wall of the second lateral corrosion-resistant airbag is connected to an inflation port. The inner wall of multiple second lateral corrosion-resistant airbags is provided with an inner support corrosion-resistant airbag adapted to the bag opening. The upper end of the inner support corrosion-resistant airbag is connected to a ring-shaped corrosion-resistant airbag. The container bag is supported and reinforced by filling inert gas. The two vertical corrosion-resistant airbags are connected by a rope loop with a lateral pull rope. The lateral pull rope pulls the side end of the container bag to prevent the side end of the container bag from protruding excessively.

[0007] Optionally, the inner wall edges of the vertical corrosion-resistant airbag, the first lateral corrosion-resistant airbag, and the second lateral corrosion-resistant airbag are provided with abrasion-resistant fabric strips, which contact the container bag body, and the vertical corrosion-resistant airbag, the first lateral corrosion-resistant airbag, and the second lateral corrosion-resistant airbag are sewn together with the outer wall of the container bag body. Optionally, each side of the container bag is provided with two vertical corrosion-resistant airbags, two first lateral corrosion-resistant airbags, and two second lateral corrosion-resistant airbags. The two airbags increase the stability of the sides of the container bag. Optionally, the annular corrosion-resistant airbag is sewn onto the bag opening, and four inner support corrosion-resistant airbags are distributed in a ring on the side wall of the annular corrosion-resistant airbag. The cross-section of the inner support corrosion-resistant airbag is designed in an "L" shape and is connected to the annular corrosion-resistant airbag and the second lateral corrosion-resistant airbag. Optionally, the inflation port is located in the middle section of the side wall of the second lateral corrosion-resistant airbag and is integrally connected to it. The inflation port has a built-in valve for inflation and deflation. Optionally, the rope loop is located at both ends of the lateral pull rope, and the rope loop is integrated with the lateral pull rope. The rope loop is knotted and wrapped around the vertical corrosion-resistant airbag and the curved tube corrosion-resistant airbag. Multiple lateral pull ropes are provided on the side wall of the container bag.

[0008] Compared with the prior art, the present invention has the following beneficial effects: Inert gas filling effectively isolates the bag from external corrosive media, protecting it from corrosion; it significantly enhances the structural stability and pressure resistance of the bag, while the double-airbag structure improves the side deformation resistance; high-strength wear-resistant fabric strips on the inner wall reduce friction damage, and stitching enhances the integrity of the airbag system and the bag body; the inner support and ring-shaped airbags form a reinforced support system at the upper port, preventing bag opening deformation or material overflow after filling; the one-way valve structure at the inflation port is easy to operate, has good sealing performance, and facilitates control of gas filling and discharging.

[0009] Adjustable tension effectively constrains the lateral side of the container bag, preventing excessive expansion of the sidewalls when fully loaded; rope loops are fixed at the airbag connection nodes to ensure uniform stress and prevent structural imbalance or rupture; multiple lateral pull ropes further enhance the overall anti-expansion and crack resistance of the bag.

[0010] The air-inflated, corrosion-resistant system and the side drawstring anti-protrusion structure of the FIBC work together to improve the overall structural stability, deformation resistance, and anti-burst capability of the FIBC. This effectively prevents excessive expansion of the sidewalls, structural imbalance, or rupture when fully loaded, while also isolating corrosive media, reducing friction damage, extending the service life of the FIBC, and ensuring safe and reliable lifting, handling, and loading / unloading processes.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1 - Figure 4 As shown, a corrosion-resistant reinforced container bag includes a container bag body 1, a bag opening 2, and reinforcing ropes 3. The bag opening 2 is located at the upper center of the container bag body 1, and four reinforcing ropes 3 are evenly connected at the four upper corners of the container bag body 1 to improve the overall force balance and stability during hoisting and handling. The outer side of the container bag 1 is fitted with a corrosion-resistant reinforcement mechanism 4. Through special design and material selection, this mechanism can effectively support and reinforce the container bag 1 in a corrosive environment. The corrosion-resistant reinforcement mechanism 4 includes vertical corrosion-resistant airbags 41, lateral corrosion-resistant airbags, and an inflation port 47. The two vertical corrosion-resistant airbags 41 are respectively arranged at the four vertical corners of the container bag 1, forming the main load-bearing and impact-resistant structure. The upper and lower ends of the vertical corrosion-resistant airbags 41 are respectively connected to the second lateral corrosion-resistant airbag 44 and the first lateral corrosion-resistant airbag 42. The three are connected and connected by the bent tube corrosion-resistant airbag 43, forming a closed and stable cuboid frame airbag system. The second lateral corrosion-resistant airbag 44 has an inflation port 47 in the middle of its side wall, which is used to inject inert gas to maintain the internal pressure and rigidity of the overall structure. The inner walls of multiple second lateral corrosion-resistant airbags 44 are also provided with inner support corrosion-resistant airbags 45 that are adapted to the bag opening 2. The upper end of the inner support corrosion-resistant airbag 45 is connected to a circular corrosion-resistant airbag 46, which together strengthens the coverage and three-dimensional support of the bag opening 2 area to prevent the bag opening 2 from deforming or the material from overflowing after filling. By filling the entire airbag system with inert gas, not only can external corrosive media be effectively isolated, but the structural stability and pressure resistance of the container bag 1 can also be significantly enhanced. The two vertical corrosion-resistant airbags 41 are connected by a rope loop 48 to a lateral pull rope 49. The lateral pull rope 49 can adjust the tension to effectively constrain the lateral side of the container bag 1, and avoid excessive expansion of the side wall when fully loaded, which could lead to structural imbalance or rupture. The inner wall edges of the vertical corrosion-resistant airbag 41, the first lateral corrosion-resistant airbag 42 and the second lateral corrosion-resistant airbag 44 are all sewn with high-strength wear-resistant fabric strips. These fabric strips are in direct contact with the outer wall of the container bag 1, which reduces friction damage and firmly connects the airbag system to the bag body through sewing, thus improving the overall integrity. Each side of the container bag 1 is provided with two vertical corrosion-resistant airbags 41, two first lateral corrosion-resistant airbags 42 and two second lateral corrosion-resistant airbags 44. The double airbag structure significantly enhances the deformation resistance of the sides and the overall stability. The circular corrosion-resistant airbag 46 is fixed to the bag opening 2 by stitching. The four inner support corrosion-resistant airbags 45 are arranged in a ring around the circular corrosion-resistant airbag 46. Their cross-section is designed in an "L" shape. They maintain air passage communication with the circular corrosion-resistant airbag 46 and the second lateral corrosion-resistant airbag 44, and together form a reinforced support system for the upper port. The inflation port 47 is located in the middle section of the side wall of the second lateral corrosion-resistant airbag 44 and is integrally formed with it. The inflation port 47 is equipped with a one-way valve structure, which facilitates the control of gas filling and discharge, and is easy to operate and has good sealing performance. The rope loops 48 are located at both ends of the lateral pull ropes 49, are integrally formed with the pull ropes, and are fixed to the connection nodes of the vertical corrosion-resistant airbags 41 and the curved corrosion-resistant airbags 43 by knotting and wrapping to ensure uniform force distribution; multiple lateral pull ropes 49 are provided on the four sides of the container bag 1 as needed to further enhance the overall anti-burst capability of the bag.

[0015] Lay the container bag 1 flat and install the corrosion-resistant reinforcement mechanism 4 on its outer side: high-strength wear-resistant fabric strips sewn along the inner edges of the vertical corrosion-resistant airbag 41, the first lateral corrosion-resistant airbag 42, and the second lateral corrosion-resistant airbag 44, which are in contact with the outer wall of the container bag 1. These three components are then securely connected to the container bag 1 by stitching, ensuring that each side has two vertical corrosion-resistant airbags 41, two first lateral corrosion-resistant airbags 42, and two second lateral corrosion-resistant airbags 44 (double airbag structure). The upper and lower ends of the vertical corrosion-resistant airbags 41 are connected to the second lateral corrosion-resistant airbags 44 and the first lateral corrosion-resistant airbags 42 via curved corrosion-resistant airbags 43, forming a closed rectangular frame airbag system. The circular corrosion-resistant... The corrosion-resistant airbag 46 is fixed to the bag opening 2 by sewing. Four internal support corrosion-resistant airbags 45 are arranged in a ring around the circular corrosion-resistant airbag 46 (with an "L" shaped cross-section) and maintain air passage communication with the circular corrosion-resistant airbag 46 and the second lateral corrosion-resistant airbag 44. At the connection node between the vertical corrosion-resistant airbag 41 and the curved tube corrosion-resistant airbag 43, the rope loop 48 (integral-formed with the lateral pull rope 49) is fixed by knotting and wrapping. The lateral pull rope 49 is connected to the rope loop 48 between the two vertical corrosion-resistant airbags 41, and the tension is adjusted to constrain the side of the container bag 1. After confirming that the one-way valve structure inside the inflation port 47 (the middle section of the side wall of the second lateral corrosion-resistant airbag 44, integrally formed) is intact, the overall assembly is completed.

[0016] Inert gas is introduced into the airbag system (vertical corrosion-resistant airbag 41, first lateral corrosion-resistant airbag 42, curved tube corrosion-resistant airbag 43, second lateral corrosion-resistant airbag 44, internal support corrosion-resistant airbag 45, and annular corrosion-resistant airbag 46) of the corrosion-resistant reinforcement mechanism 4 through the air inlet 47 until the airbag maintains internal pressure and rigidity, and the one-way valve is closed. Material is loaded through the bag opening 2. The upper port reinforcement support system formed by the internal support corrosion-resistant airbag 45 and the ring-shaped corrosion-resistant airbag 46 prevents the bag opening 2 from deforming or the material from spilling out. The bag is hoisted using four reinforcing ropes 3 (at the four corners of the upper end of the container bag 1). The lateral ropes 49 restrain the container bag 1 laterally to prevent excessive expansion of the side walls. After being transported to the target location, the bag opening 2 is opened to unload the material. The gas in the airbag system is discharged through the inflation port 47, and the container bag 1 is folded for storage.

[0017] Confirm that the one-way valve of the inflation port 47 is closed, and connect the inflation tube to the inflation port 47; open the one-way valve and inflate the airbag system (vertical corrosion-resistant airbag 41, first lateral corrosion-resistant airbag 42, curved corrosion-resistant airbag 43, second lateral corrosion-resistant airbag 44, internal support corrosion-resistant airbag 45, and annular corrosion-resistant airbag 46) with inert gas; after the airbag system reaches the required internal pressure and rigidity, close the one-way valve and remove the inflation tube.

[0018] Operate the one-way valve structure inside the inflation port 47 to open the valve; the gas in the airbag system is discharged through the inflation port 47; after the gas is completely discharged, close the one-way valve.
