Technical Field

[0001] This utility model relates to the field of stacking bin technology, specifically to a multi-layer composite stacking bin suitable for the storage of hazardous chemicals. Background Technology

[0002] The reference patent is titled: "A Composite Multilayer High-Stiffness High-Temperature Resistant Stacking Bucket" (Authorization Announcement No.: CN206678479U, Authorization Announcement Date: 2017.11.28). It includes an outer layer, a core layer, and an inner layer. The outer and inner layers are both HDPE layers. The core layer includes a high-temperature barrier layer, an HDPE foam layer, and a structural reinforcement layer arranged from the outside in. The thickness of the HDPE foam layer is 0.6–1.0 mm, while the thickness of the inner and outer layers is 0.5–0.8 mm. The thickness of the high-temperature barrier layer is 30–50 μm, and the thickness of the structural reinforcement layer is 60–100 μm. This stacking bucket is lighter and stiffer, and it also has excellent high-temperature resistance.

[0003] Based on the aforementioned documents, the storage of hazardous chemicals is crucial in many industries such as chemical and pharmaceutical manufacturing. Currently, there are numerous types of containers available for storing hazardous chemicals on the market, but they generally suffer from several problems. For example, some storage barrels are made of a single material, which cannot effectively resist the corrosion of hazardous chemicals, leading to barrel damage and leakage of hazardous chemicals. This not only wastes resources but also poses a serious threat to the environment and personnel safety. At the same time, some storage barrels lack sufficient cushioning and load-bearing capacity, making them prone to deformation due to collisions and compression during handling and stacking, affecting storage effectiveness and service life. Furthermore, existing storage barrels are not accurately positioned during stacking, easily resulting in slippage and displacement, leading to unstable stacking and potential safety hazards. Therefore, this utility model provides a multi-layer composite structure stacking barrel suitable for storing hazardous chemicals. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-layer composite stacking drum suitable for the storage of hazardous chemicals, which solves the problems of poor corrosion resistance, insufficient buffering and load-bearing capacity, and inaccurate stacking positioning of existing stacking drums, resulting in insufficient stability.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a multi-layer composite stacking barrel suitable for the storage of hazardous chemicals, including a barrel body and a barrel lid, wherein the barrel lid is sealed to the feed inlet at the top of the barrel body, and foldable and retractable lifting handles are symmetrically arranged on both sides of the barrel body, and a barrel base is integrally formed at the bottom of the barrel body, wherein a stacking positioning component is provided inside the barrel base, and the barrel body is a multi-layer composite structure, wherein from the inside to the outside, an anti-corrosion inner layer, a reinforced buffer layer, a load-bearing support layer and an anti-aging outer layer are arranged sequentially; The anti-corrosion inner layer has a composite corrosion-resistant structure, consisting of a dense isolation layer, a penetration barrier layer, and a bonding reinforcement layer arranged sequentially from the inside out.

The penetration barrier layer is made of perfluoroether rubber, and its interior contains nano-sized ceramic particles, which are made of alumina and have a particle size of 50-100 nm. The bonding reinforcement layer is made of modified polyolefin, and its surface is provided with interlocking textures, which are serrated and distributed on the outer surface of the bonding reinforcement layer.

[0006] Preferably, the reinforcing buffer layer is made of modified polyurethane foam, with a metal fiber mesh embedded inside. The metal fiber mesh is made of stainless steel and has a honeycomb structure.

[0007] Preferably, the load-bearing support layer is made of high-strength polyethylene, and has annular reinforcing ribs and longitudinal reinforcing ribs inside, and the annular reinforcing ribs and longitudinal reinforcing ribs are cross-connected to form a grid-like support structure.

[0008] Preferably, the anti-aging outer layer is made of polypropylene with added UV stabilizers, and its outer surface is coated with an antistatic coating.

[0009] Preferably, a symmetrical positioning block is fixedly connected to the top of the barrel body, the surface of the positioning block is provided with a positioning groove, and the bottom of the barrel base is provided with an assembly groove that matches the positioning block.
