Description

Technical Field

[0001] This application relates to the field of steel drum technology, and more particularly to a steel drum with an inner anti-corrosion coating. Background Technology

[0002] Steel drums are a traditional container, holding a very important position among them. From their initial function of temporarily storing goods, steel drums have evolved into industrial packaging, sales packaging, and transport packaging, forming a continuous flow container from production to distribution and consumption, becoming a means of long-term preservation of contents. Traditional steel drums often only use a single rust-proofing treatment on their inner walls. When exposed to corrosive materials such as acids and alkalis, the inner walls are prone to corrosion and damage, leading to material contamination or leakage, shortening the lifespan of the drum, and increasing replacement costs for companies. Furthermore, during transportation and stacking, steel drums are easily deformed due to external pressure and collisions, especially at the middle and top sealing areas, where structural damage can occur, affecting sealing performance and safety.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] Example 1:

[0021] Please see Figure 1-4In this utility model, a steel drum with an inner anti-corrosion coating includes a steel drum body 1. A sealing plate 2 is provided on the upper surface of the steel drum body 1. A groove 4 is formed on the upper surface of the steel drum body 1, and a sealing gasket 5 is connected inside the groove 4. A locking block 6 is connected to the bottom surface of the sealing plate 2, and the groove 4 and the locking block 6 are compatible. Multiple reinforcing rings 7 are connected to the outer surface of the steel drum body 1, and multiple reinforcing rods 8 are connected to the outer surface of each reinforcing ring 7. An inner lining layer 9 is connected to the inner wall of the steel drum body 1, and an anti-corrosion coating 10 is connected to the inner wall of the inner lining layer 9. With a nano-grade silica modified layer 11, the inner lining layer 9, the anti-corrosion coating 10, and the nano-grade silica modified layer 11 can effectively resist the erosion of the steel drum body 1 by acid and alkali corrosive materials, avoid the problem of rust and damage to the inner wall, prevent the material from being contaminated or leaking due to container damage, greatly extend the service life of the steel drum, and reduce the cost incurred by enterprises due to frequent replacement of steel drums. Through the reinforcing ring 7 and the reinforcing rod 8, a synergistic support structure is formed, which can effectively improve the drum body's ability to resist external extrusion and collision, and reduce the probability of deformation of the steel drum during transportation and stacking.

[0022] Example 2:

[0023] Two pull rods 3 are connected to the outer surface of the steel drum body 1. Both pull rods 3 are equipped with anti-slip rubber sleeves on their outer surfaces. These two pull rods 3 with anti-slip rubber sleeves on the outer surface of the steel drum body 1 facilitate the handling and movement of the steel drum by operators, increasing ease of use. The bottom surface of the steel drum body 1 is equipped with an anti-slip base made of rubber. The rubber anti-slip base on the bottom surface of the steel drum body 1 increases the friction between the steel drum and the ground, preventing the steel drum from sliding when placed or stacked. This adapts to the storage and transportation needs in industrial scenarios and improves overall ease of use. Both the outer surface of the steel drum body 1 and the outer surface of the sealing plate 2 are equipped with an anti-rust layer made of polyethylene. The polyethylene anti-rust layer on the outer surfaces of the steel drum body 1 and the sealing plate 2 can effectively form a dense protective film, isolating moisture, oxygen, and external corrosive impurities in the air, thus preventing rust caused by oxidation or chemical reactions on the outer surfaces of the steel drum body 1 and the sealing plate 2 from the source.

[0024] The sealing gasket 5 is made of nitrile rubber, and the anti-corrosion coating 10 is made of epoxy coal tar. The use of nitrile rubber gasket 5 effectively fills the sealing gap and enhances the top sealing performance. The steel drum body 1 is made of low-carbon steel, while each reinforcing ring 7 and reinforcing rod 8 is made of stainless steel. The use of low-carbon steel for the steel drum body 1 provides it with good plasticity, toughness, and weldability, meeting the load-bearing requirements for the storage and transportation of conventional materials. Simultaneously, the ease of processing ensures the high efficiency of steel drum production, suitable for industrial mass production scenarios. The use of stainless steel reinforcing rods 8 and reinforcing rings 7 provides excellent corrosion resistance and high strength. It has good resistance to deformation and is not easily corroded in industrial environments such as humidity, acid and alkali, and dust. The inner lining layer 9 is made of polyethylene, and the nano-grade silica modified layer 11 is made of nano-grade silica modified epoxy resin. The upper surface of the sealing plate 2 has a circular groove, and the inner wall of the circular groove is provided with a wear-resistant polytetrafluoroethylene patch. Through the circular groove on the outer surface and the wear-resistant polytetrafluoroethylene patch on the inner wall of the circular groove, the wear resistance of the sealing plate 2 surface can be improved and its service life can be extended. The top edge of the steel drum body 1 is provided with an annular boss, and the outer surface of the annular boss is provided with a red warning paint layer. Through the annular boss and the red warning paint layer, a safety warning function can be played and the safety of use can be improved.

[0025] The working principle of this application is:

[0026] In use, the polyethylene inner liner 9 serves as the first barrier, isolating the material from the steel drum body 1. Simultaneously, the epoxy coal tar anti-corrosion coating 10 possesses strong corrosion resistance, resisting material erosion. Furthermore, the nano-grade silica modified layer 11 utilizes the density of nanomaterials to reduce material penetration. This three-layer structure works synergistically to achieve efficient corrosion protection. Reinforcing rings 7 are distributed along the drum's axial direction, enhancing the drum's resistance to radial compression. Meanwhile, reinforcing rods 8 connect to the reinforcing rings 7 along the circumferential direction, forming an overall support to resist axial impact and deformation, ensuring the stability of the drum structure. A mechanical seal is achieved through the matching structure of the locking block 6 and the locking groove 4. The nitrile rubber sealing gasket 5 fills the gaps, preventing material leakage from the seal. The rust-proof layer on the outer surface prevents the steel drum itself from rusting, indirectly ensuring sealing performance.

[0027] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present application, based on the technical solution and concept of the present application, should be covered within the scope of protection of the present application.
