[0002] With the acceleration of urbanization, the scale and complexity of buildings are constantly increasing, making the demand for building fire safety and environmental protection and energy conservation more and more urgent. Traditional ventilation ducts, such as galvanized iron ducts, are prone to rust, are noisy, have serious air leakage, and thermal bridges cause significant energy loss. Although fiberglass ducts solve the rust problem to some extent, their organic materials are flammable when exposed to fire and release large amounts of dense smoke and toxic gases, which is contrary to current fire protection standards.

[0003] Currently available double-sided fireproof inorganic environmentally friendly composite air ducts have poor fire resistance, and the connecting plates used to connect to other pipes will be damaged after long-term use. When they are damaged, the entire duct needs to be replaced, which has great limitations and poor practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of poor fire resistance in the existing technology, and the fact that the connecting plate used to connect to other pipes will be damaged after long-term use. When it is damaged, it needs to be replaced as a whole, which has great limitations and poor practicality. The proposed double-sided fireproof inorganic environmentally friendly composite air duct is to solve these problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a double-sided fireproof inorganic environmentally friendly composite air duct, comprising an air duct body, a first connecting block installed on the outer wall of one end of the air duct body, a first connecting plate fixed on the outer wall of the first connecting block, a second connecting plate sleeved on the outer wall of the other end of the air duct body, a second connecting block installed on one end of the second connecting plate on the outer wall of the air duct body by a second bolt, a protective fireproof plate sleeved between the first connecting block and the second connecting plate on the outer side of the air duct body, a fireproof coating provided inside the air duct body, a sound insulation layer provided outside the fireproof coating, and a base layer provided outside the sound insulation layer.

[0006] Preferably, one end of the first connecting block is fixed with an mounting plate, the mounting plate is fixed to the air duct body by a first bolt, and mounting holes are provided at the four corners of the first and second connecting plates.

[0007] Preferably, a sealing plate is fixed at one end of the duct body near the first connecting plate, and a sealing groove matching the sealing plate is opened at one end of the duct body near the second connecting plate.

[0008] Preferably, a first opening matching the second connecting block is provided between the first connecting block and the sealing plate.

[0009] Preferably, an adhesive layer is provided between the fireproof coating, the sound insulation layer and the base layer, and the fireproof coating, the sound insulation layer and the base layer are fixed together by the adhesive layer.

[0010] Preferably, the outer wall of the duct body has a second opening that matches the mounting plate and the first bolt.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the first connecting block, mounting plate, and first bolt allow for the individual disassembly and replacement of the first connecting plate. Similarly, the second connecting block and second bolt enable the individual installation and disassembly of the second connecting plate. The fireproof protective plate provides fire protection to the outer side of the duct body, and since it is snapped between the first connecting block and the second connecting plate, the fireproof protective plate can be easily disassembled and replaced when the first connecting block and the second connecting plate are disassembled, enhancing its practicality. Furthermore, the fireproof coating provides fire protection to the inner wall of the duct body, achieving double-sided fire protection and further enhancing its practicality. Finally, the sound insulation layer provides sound insulation to the duct body. Attached Figure Description

A second connecting block 6 is installed on the outer wall of the air duct body 1 by a second bolt 7 at one end of the second connecting plate 5. A protective fireproof plate 13 is sleeved between the first connecting block 2 and the second connecting plate 5 on the outer side of the air duct body 1. A fireproof coating 15 is provided inside the air duct body 1. A sound insulation layer 16 is provided on the outer side of the fireproof coating 15. A base layer 17 is provided on the outer side of the sound insulation layer 16.

[0021] The overall effect of Embodiment 1 is that, through the setting of the first connecting block 2, the mounting plate 11 and the first bolt 12, the first docking plate 3 can be disassembled and replaced individually. Through the setting of the second connecting block 6 and the second bolt 7, the second docking plate 5 can be installed and disassembled individually. Through the setting of the protective fireproof plate 13, the outer side of the duct body 1 can be protected and fireproofed. The protective fireproof plate 13 is snapped between the first connecting block 2 and the second docking plate 5. When the first connecting block 2 and the second docking plate 5 are disassembled individually, the protective fireproof plate 13 can be disassembled and replaced, which is more practical. In addition, through the setting of the fireproof coating 15, the inner wall of the duct body 1 also has a fireproof effect, achieving a double-sided fireproof effect, which is more practical.

[0022] Example 2, as Figure 1-4As shown, a mounting plate 11 is fixed to one end of the first connecting block 2. The mounting plate 11 is fixed to the duct body 1 by the first bolt 12. Mounting holes 14 are provided at the four corners of the first connecting plate 3 and the second connecting plate 5. A sealing plate 4 is fixed to one end of the duct body 1 near the first connecting plate 3. A sealing groove 8 matching the sealing plate 4 is provided to one end of the duct body 1 near the second connecting plate 5. A first opening 9 matching the second connecting block 6 is provided between the first connecting block 2 and the sealing plate 4. An adhesive layer 18 is provided between the fireproof coating 15, the sound insulation layer 16 and the base layer 17. The fireproof coating 15, the sound insulation layer 16 and the base layer 17 are fixed together by the adhesive layer 18. A second opening 10 matching the mounting plate 11 and the first bolt 12 is provided on the outer wall of the duct body 1.

[0023] The overall effect of Embodiment 2 is as follows: through the setting of the first connecting block 2, the mounting plate 11 and the first bolt 12, the first docking plate 3 can be disassembled and replaced individually. through the setting of the sealing plate 4 and the sealing groove 8, the sealing plate 4 can be inserted into the sealing groove 8 and fill the sealing groove 8 when the two air duct bodies 1 are installed together, so as to avoid air leakage at the docking point of the two air duct bodies 1 and enhance stability. through the setting of the sound insulation layer 16, the air duct body 1 has a sound insulation effect. through the setting of the second opening 10, the outer wall of the air duct body 1 is reserved with holes for the mounting plate 11 and the first bolt 12, so as to avoid the first bolt 12 pressing against the protective fireproof plate 13 and causing it to be unable to be installed. through the setting of the adhesive layer 18, the fireproof coating 15, the sound insulation layer 16 and the base layer 17 are more tightly bonded, and the practicality is enhanced.

[0024] Working Principle: In use, the first connecting block 2, mounting plate 11, and first bolt 12 allow for the individual disassembly and replacement of the first connecting plate 3. Similarly, the second connecting block 6 and second bolt 7 allow for the individual installation and removal of the second connecting plate 5. The protective fireproof plate 13 provides fire protection for the outer side of the duct body 1. The fireproof plate 13 is snapped between the first connecting block 2 and the second connecting plate 5. When the first connecting block 2 and the second connecting plate 5 are disassembled individually, the fireproof plate 13 can be disassembled and replaced. The device is more robust, and the fire-retardant coating 15 provides fire resistance to the inner wall of the duct body 1, achieving double-sided fire protection and enhancing its practicality. The sound insulation layer 16 provides sound insulation to the duct body 1. The second opening 10 provides holes for the mounting plate 11 and the first bolt 12 on the outer wall of the duct body 1, preventing the first bolt 12 from pressing against the protective fireproof plate 13 and causing installation problems. The adhesive layer 18 ensures a tighter bond between the fire-retardant coating 15, the sound insulation layer 16, and the base layer 17, further enhancing its practicality.
