Description

Technical Field

[0001] The present invention relates to the technical field of aluminum coils, and specifically to a double-layer fireproof structure for aluminum coils. Background Art

[0002] An aluminum coil refers to a form of aluminum sheet that has been processed by rolling. It is a continuous coil formed by processing an aluminum billet through a continuous rolling process, with a relatively thin thickness and a large width. Aluminum coils are usually supplied in coil form and can be cut and processed as needed. Aluminum coils are commonly used in various application fields, including construction, electronics, automotive, packaging, etc. It has many advantages, such as being lightweight, corrosion-resistant, having good electrical conductivity, being easy to form and process, etc., and thus is widely used in many industries. The specifications and characteristics of aluminum coils can be determined according to specific requirements and applications. Common aluminum coil specifications include thickness, width, and coil weight, etc. The thickness of aluminum coils is usually between dozens of micrometers and several millimeters, and the width can range from dozens of millimeters to several meters. Depending on different alloys and treatment states, aluminum coils can also have different mechanical properties and surface characteristics. A fireproof aluminum coil is an aluminum coil product that has been specially treated to improve its fireproof performance. It is usually a coiled product made of aluminum alloy material and has undergone a series of fireproof treatment measures to reduce the risk of fire and the spread of fire. Fireproof aluminum coils have the following characteristics: Flame retardancy: Fireproof aluminum coils have a high flame retardancy and can resist the spread and combustion of flames, thereby reducing the possibility of fire occurrence and expansion; Fireproof coating: Fireproof aluminum coils usually have a fireproof coating on the surface, and this coating has a flame retardant effect and can resist flames and high temperatures; Heat insulation layer: Fireproof aluminum coils may have a heat insulation layer added to the back or inside to reduce heat conduction and heat reflection and slow down the spread of fire.

[0003] However, the existing aluminum coils have the following problems during use: Most aluminum coils have a simple plate-like structure. Although aluminum itself is non-combustible, under specific conditions, aluminum coils may have a negative impact on the development and spread of fire. Thermal conductivity: Aluminum is a metal with good thermal conductivity. When an aluminum coil is in a fire environment, its thermal conductivity may cause the rapid spread and expansion of fire; Flame reflection: The reflection performance of the aluminum surface will reflect the flame, which may cause other combustibles to catch fire or intensify the fire; Aluminum dust explosion risk: In some special industrial environments, aluminum dust may be formed. When the aluminum dust and oxygen in the air reach a certain ratio, a combustible mixture will be formed. Once it encounters an ignition source, it may trigger an explosion. Therefore, corresponding technical solutions need to be designed to solve the existing technical problems. Summary of the Invention

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1-6 , the present invention provides a technical solution: a double-layer fire prevention structure for an aluminum coil, which includes an aluminum coil base layer 1, an aluminum coil outer layer 2, partition columns 3 and a fire prevention mechanism 4. Two groups of aluminum coil outer layers 2 are provided and symmetrically distributed on both sides of the aluminum coil base layer 1. A hollow cavity 5 is formed between the aluminum coil outer layer 2 and the aluminum coil base layer 1, and an edge sealing strip 6 is provided at the edge connection of the two. Several groups of partition columns 3 are provided and evenly distributed in the hollow cavity 5. Several groups of partition columns 3 are evenly fixed on the surface of the aluminum coil base layer 1. Several groups of strip-shaped installation openings 7 are formed on the surface of the aluminum coil outer layer 2. Two groups of split blades 8 are symmetrically arranged inside the strip-shaped installation openings 7. Arc-shaped blades 9 are provided at both ends of the split blades 8. The outer end of the arc-shaped blade 9 is connected to the inner wall of the strip-shaped installation opening 7 and the inner end is connected to the split blade 8. A separation strip 10 is fixed inside the arc-shaped blade 9. Adjacent two groups of separation strips 10 are equidistantly distributed. The fire prevention mechanism 4 is built in the partition column 3. The fire prevention mechanism 4 includes a base 11, an elastic column 12 and a receiving ball 13. The base 11 is fixed on the aluminum coil base layer 1 and the outer end is connected to the receiving ball 13 through the elastic column 12. The receiving ball 13 is filled with a fire extinguishing agent and a nozzle 14 is opened at the outer end. The receiving ball 13 is placed in the partition column 3. When the aluminum coil encounters an open flame, when the high temperature acts on the strip-shaped installation opening 7, the expansion ball 18 located inside the strip-shaped installation opening 7 expands due to heat and causes the two separation strips 10 to separate, forming a gap between the separation strips 10. At this time, the elastic column 12 abuts against the receiving ball 13, and the receiving ball 13 is squeezed so that the internal fire extinguishing agent sprays out along the moving groove 20, and the open flame around the aluminum coil is assisted in extinguishing.

[0025] Further improved, as Figure 3 shown: The edge sealing strip 6 is in a strip-like structure and wraps around the edges of the aluminum coil base layer 1 and the aluminum coil outer layer 2. The surface of the edge sealing strip 6 is processed into a laminated structure, which can achieve the edge sealing of the aluminum coil base layer 1 and the aluminum coil outer layer 2 while ensuring that the aluminum coil can be deformed.

[0026] Further improved, as Figure 1 shown: A plurality of groups of strip-shaped mounting openings 7 are evenly distributed along the arc of the aluminum coil outer layer 2, and the adjacent two groups of strip-shaped mounting openings 7 are equidistantly distributed. The strip-shaped mounting openings 7 located on the aluminum coil outer layer 2 facilitate the export of the fire extinguishing agent.

[0027] Further improved, as Figure 4 shown: The arc-shaped blade 9 is in a fan-shaped structure and the surface is processed into a laminated structure, which is adaptively adjusted in cooperation with the deformation adjustment of the split blade 8.

[0028] Further improved, as Figure 4 shown: A plurality of groups of extrusion grooves 15 are processed on the outer side of the split blade 8 and a plurality of groups of tooth grooves 16 are processed on the inner side. The plurality of groups of extrusion grooves 15 are distributed in a laminated manner, and the adjacent two groups of tooth grooves 16 are connected end to end. The separation strip 10 is fixed between the plurality of groups of tooth grooves 16. Such a design method facilitates the telescopic adjustment process of the split blade 8.

[0029] Further improved, as Figure 5 shown: The separation strip 10 includes a copper wire 17 and an expansion ball 18 processed at the corner of the copper wire 17. The copper wire 17 is in a corrugated structure and fits with the inner wall of the tooth groove 16. An expansion cavity 19 is formed inside the expansion ball 18 and copper material is used. The expansion ball 18 expands when heated and separates the two separation strips 10. A gap is formed between the separation strips 10 to facilitate the ejection of the fire extinguishing agent.

[0030] Further improved, as Figure 6 shown: The partition column 3 is in a quadrangular pyramid structure and a moving groove 20 is formed inside. The upper end of the partition column 3 is located between the two separation strips 10. Such a design method can eject the fire extinguishing agent along the moving groove 20 during the opening process of the separation strips 10.

[0031] Specifically, the receiving ball 13 is in a spherical structure and made of an elastic metal material. The outer wall of the receiving ball 13 abuts against the inner wall of the moving groove 20. Such a design method facilitates the extrusion and ejection of the fire extinguishing agent inside the receiving ball 13.

[0032] In use: When a fire occurs to the aluminum coil of the present invention, when the high temperature acts on the strip-shaped mounting opening 7, the expansion balls 18 located inside the strip-shaped mounting opening 7 expand upon heating and cause the two separation strips 10 to separate, creating a gap between the separation strips 10. At this time, the elastic columns 12 abut against the receiving balls 13, and the receiving balls 13 are squeezed so that the fire extinguishing agent inside is ejected along the moving grooves 20, achieving the purpose of assisting in extinguishing the fire around the aluminum coil. In addition, the surface of the edge sealing strip 6 located at the edge of the aluminum coil is formed into a laminated structure, which can achieve edge sealing of the aluminum coil base layer 1 and the aluminum coil outer layer 2 while ensuring that the aluminum coil can deform.
