Description

Technical Field

[0001] This utility model relates to the field of air duct technology, and in particular to an integrated floating bead silicon crystal air duct. Background Technology

[0002] Perlite silica crystal fire-resistant composite air duct is a new type of smoke control and ventilation duct that uses perlite silica crystal fire-resistant board. Perlite silica crystal fire-resistant board is a lightweight, high-temperature resistant, rigid material that overcomes the shortcomings of silicate fire-resistant boards, such as heavy weight and poor thermal insulation. It also solves the problems of low strength and easy fiber shedding of flexible fire-resistant materials such as rock wool and aluminum silicate wool. It possesses fire-resistant and heat-insulating properties, making it more suitable for fire-resistant and heat-insulating applications in smoke control and ventilation ducts compared to other fireproof and fire-resistant materials. The duct connection profiles use dedicated steel integrated flanges, which have high connection strength and ease of assembly.

[0003] Existing perlite-silicon crystal refractory composite ducts lack corresponding reinforcing components to enhance wind pressure resistance and are also inconvenient to install. For example, patent CN221075631U discloses an integrated perlite-silicon crystal refractory duct, including a duct body and a flange. The duct body lacks corresponding reinforcing components, resulting in low wind pressure resistance. Furthermore, the groove between the outer and inner necks of the flange extension lacks corresponding limiting components, hindering quick positioning and installation. Therefore, to solve the above technical problems, this application provides an integrated perlite-silicon crystal duct that is easy to install and has good wind pressure resistance. Utility Model Content

[0004] The purpose of this invention is to provide an integrated perlite silicon crystal air duct that is easy to install, has good air sealing, excellent fire resistance and heat insulation performance, high strength, long service life, and good wind pressure resistance.

The side of the mounting part is provided with an inner fixing plate and an outer fixing plate. The outer fixing plate is located around the inner fixing plate.

[0006] Preferably, the duct body is provided with an inner layer of color steel plate, a perlite silicon crystal fire-resistant insulation plate, and an outer layer of color steel plate from the inside out.

[0007] Preferably, the outer fixing plate and the inner fixing plate are disposed on the same side, and the height of the inner fixing plate is greater than the height of the outer fixing plate.

[0008] Preferably, the outer fixing plate and the inner fixing plate are arranged perpendicularly to the mounting part, and an mounting groove for installing the duct body is formed between the outer fixing plate and the inner fixing plate.

[0009] Preferably, the side of the mounting groove is provided with a groove, and the inside of the groove is provided with a limiting component. The limiting component includes a limiting block. The surface of the duct body is provided with a limiting groove that matches the limiting block. The center of the limiting block is provided with a rotating shaft, and the two ends of the rotating shaft are provided with adjusting blocks. The adjusting blocks are located in the groove.

[0010] Preferably, the adjusting block is T-shaped, with its side connected to the rotating shaft, its upper end set in the groove, and its lower end provided with a spring. One end of the spring is connected to the adjusting block, and the other end of the spring is connected to the groove.

[0011] Preferably, the outer fixing plate and the inner fixing plate are provided with fixing holes for fixing the air duct body.

[0023] Example

[0024] like Figure 1 As shown, the integrated beaded silicon crystal air duct includes an air duct body 1. The outer surface of the air duct body 1 is provided with reinforcing ribs 3, which are fixed to the surface of the air duct body 1 by bolts or special adhesive. Multiple reinforcing ribs 3 can be provided. Figure 1 The middle section consists of two intersecting reinforcing ribs 3.

[0025] like Figure 2 As shown, two adjacent duct bodies 1 are connected by a connecting flange 2. The connecting flange 2 includes a mounting part 6, the surface of which is provided with mounting holes 4 for installation. An inner fixing plate 8 and an outer fixing plate 9 are provided on the side of the mounting part 6, with the outer fixing plate 9 located around the inner fixing plate 8. The surfaces of the outer fixing plate 9 and the inner fixing plate 8 are provided with fixing holes 5 for fixing the duct body 1.

[0026] like Figure 3 As shown, the outer fixing plate 9 and the inner fixing plate 8 are arranged on the same side, with the inner fixing plate 8 being taller than the outer fixing plate 9. The taller inner fixing plate 8 provides better sealing for the duct body 1 and better supports it. The outer fixing plate 9 and the inner fixing plate 8 are arranged perpendicularly to the mounting part 6, forming a mounting groove 7 between them for installing the duct body 1. During installation, the duct body 1 is inserted into the mounting groove 7 and secured using the fixing holes 5. The taller inner fixing plate 8 further improves the sealing between adjacent duct bodies 1.

[0027] like Figure 4As shown, the mounting groove 7 has a groove 14 on its side, that is, the side of the outer fixing plate 9 opposite to the inner fixing plate 8 has a groove 14. A limiting component is provided inside the groove 14, which includes a limiting block 10. The surface of the duct body 1 has a limiting groove (not shown) that matches the limiting block 10. A rotating shaft 11 is provided at the center of the limiting block 10, and adjusting blocks 12 are provided at both ends of the rotating shaft 11. The adjusting blocks 12 are located in the groove 14. The adjusting blocks 12 are T-shaped. The side of the adjusting block 12 is connected to the rotating shaft 11. The upper end of the adjusting block 12 is located in the groove 14. A spring 13 is provided at the lower end of the adjusting block 12. One end of the spring 13 is connected to the adjusting block 12, and the other end of the spring 13 is connected to the groove 14. A clearance groove (not shown) is provided directly below the rotating shaft 11, so that the height of the rotating shaft 11 can be adjusted up and down with the limiting block 10.

[0028] Under the action of spring 13, the height of limit block 10 can be adjusted up and down. During installation, the duct body 1 is locked inside the mounting groove 7 by the cooperation of limit block 10 and limit groove. At the same time, limit block 10 restricts the position of duct body 1 to prevent it from shaking. Then, duct body 1 is fixed through fixing hole 5. The cooperation between limit block 10 and limit groove can realize the quick positioning and installation of duct body 1.

[0029] like Figure 5 As shown, the duct body 1 is provided with an inner layer of color steel plate 15, a perlite silicon crystal fire-resistant insulation board 16, and an outer layer of color steel plate 17 from the inside out. The inner layer of color steel plate 15 can be set to 0.2mm, the perlite silicon crystal fire-resistant insulation board 16 can be set to 20mm, and the outer layer of color steel plate 17 can be set to 0.2mm, so as to achieve excellent fire resistance.

[0030] Therefore, the integrated floating bead silicon crystal air duct of this utility model with the above-mentioned structure is easy to install, has good air duct sealing, excellent fire resistance and heat insulation performance, high strength, long service life, and good wind pressure resistance.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
