Description

Technical Field

[0001] The utility model relates to the field of air ducts, in particular to a basalt fiber metal composite pipe capable of reducing consumption and noise. Background Art

[0002] In modern buildings with a large number of people, a ventilation system is required to be installed throughout the entire building. The ventilation system can achieve multiple effects such as ventilation, heat conduction and cooling, and humidity maintenance, and can quickly diffuse and discharge smoke in the event of a fire.

[0003] Existing air ducts can be specifically divided into ventilation ducts, smoke exhaust ducts and fire ducts. Among them, the fire duct is not only used for ventilation and air exchange of the building, but also needs to discharge the smoke generated by the fire outside the building when a fire occurs. Therefore, both the fire duct and the smoke exhaust duct need to meet certain fire prevention and high temperature resistance requirements. The following content is illustrated by fire ducts. However, the existing fire ducts are mainly made of metal materials such as stainless steel and galvanized steel plates, which have the problem of high cost of use; and during ventilation, energy and noise are easily diffused outward through the metal fire duct, so there are also problems of large energy loss and high noise; finally, the fire resistance effect of the fire duct made of metal as the main material is not ideal, and it cannot meet the actual requirements of the fire resistance limit, and cannot effectively guarantee the safety of the use environment. Therefore, when using it, it is necessary to take measures such as installing fireproof wraps to improve the integrity and thermal insulation of the fire duct so that it can meet the use requirements, but there is a problem of reducing the aesthetics of the fire duct, making the fire duct bloated and occupying more space.

[0004] Therefore, we propose a fireproof air duct that uses composite materials as the main material and can reduce energy consumption and noise. Utility Model Content

[0005] The main purpose of the utility model is to propose a basalt fiber metal composite pipe that can reduce consumption and noise, aiming to solve the technical problems of existing fire-fighting air ducts, such as high cost of use, unsatisfactory fire-fighting effect, large energy loss and high noise.

[0006] To achieve the above-mentioned purpose, the utility model provides a basalt fiber metal composite pipe capable of reducing consumption and noise, comprising a hollow and cylindrical air duct shell, wherein an air inlet and an air outlet are respectively provided at both ends of the air duct shell;

[0007] The air duct shell includes a first metal plate, a fiber reinforced calcium silicate board and a second metal plate. The first metal plate is arranged on the inner side of the fiber reinforced calcium silicate board, and the second metal plate is arranged on the outer side of the fiber reinforced calcium silicate board. A high temperature resistant adhesive layer is provided between the first metal plate and the fiber reinforced calcium silicate board, and between the fiber reinforced calcium silicate board and the second metal plate.

[0008] Optionally, the first metal plate is a galvanized steel plate.

[0009] Optionally, the fiber-reinforced calcium silicate board is a basalt fiber-reinforced calcium silicate board.

[0010] Optionally, connection flanges are provided at the ends of both ends of the air duct housing.

[0011] Optionally, the thickness of the first metal plate ranges from 0.5 mm to 1.2 mm.

[0012] Optionally, the fiber reinforced calcium silicate board has a thickness ranging from 5 mm to 12 mm.

[0013] Optionally, the thickness of the second metal plate ranges from 0.25 mm to 0.5 mm.

[0014] Optionally, the second metal plate is a galvanized steel plate.

[0015] Optionally, it also includes a composite socket-type angle wrap, wherein the air duct shell is in a rectangular shape, and the composite socket-type angle wrap is arranged at the edge of the air duct shell along the length direction of the air duct shell, and the two ends of the composite socket-type angle wrap are respectively provided with a first socket part and a second socket part, and the first socket part of one air duct body can be plugged into the second socket part of the other air duct body.

[0016] The technical solution of the utility model has the following beneficial effects:

[0017] The sandwich structure of fiber-reinforced calcium silicate board can reduce the cost of use, and can also reduce energy loss and noise during ventilation. Compared with fire ducts made of metal as the main material, the basalt fiber metal composite pipe that can reduce energy consumption and noise is made of fiber-reinforced calcium silicate board as the main material, so it can reduce the cost of using new ducts. In addition, fiber-reinforced calcium silicate board has lower thermal conductivity and better sound insulation performance than metal materials, so it can reduce energy loss and noise during ventilation.

[0018] In addition, the basalt fiber metal composite pipe that can reduce energy consumption and noise includes a first metal plate, a fiber reinforced calcium silicate board and a second metal plate. The first metal plate and the second metal plate can realize the ventilation and other functions of the existing fire-fighting air duct, and the sandwich structure of the fiber reinforced calcium silicate board can be used to effectively improve the fire resistance and thermal insulation of the fire-fighting air duct, thereby meeting the fire resistance limit requirements. Therefore, there is no need to install fireproof wrapping and other measures, which improves the aesthetics of the fire-fighting air duct and reduces space occupancy.

[0029] The utility model provides a basalt fiber metal composite pipe which can reduce consumption and noise.

[0030] like Figures 1 to 4 As shown, in one embodiment of the utility model, the basalt fiber metal composite pipe that can reduce power consumption and noise is referred to as a basalt fiber composite air duct, also known as GBFP. It includes an air duct shell 100 that is hollow inside, rectangular and cylindrical, and the two ends of the air duct shell 100 are respectively provided with an air inlet and an air outlet. The air enters the air duct shell 100 from the air inlet and then exits the air duct shell 100 from the air outlet, wherein the air inlet and the air outlet are divided according to the direction of air flow, and are not a limitation of the basalt fiber metal composite pipe that can reduce power consumption and noise. Specifically, a connecting flange 200 is provided at the ends of both ends of the air duct shell 100, and the two air duct shells 100 can be connected to each other through their respective connecting flanges 200.

[0031] Furthermore, composite socket-type corners 140 are provided at the four edges on the side of the air duct shell 100. The composite socket-type corners 140 specifically include metal and basalt fiber, which protect the air duct shell 100; and the composite socket-type corners 140 are arranged along the length direction of the air duct shell 100, and a first socket part and a second socket part are respectively provided at both ends of the composite socket-type corner 140. The first socket part is specifically an end extending forward, and the second socket part is the other end provided with a slot. When two air duct shells 100 are connected, the composite socket-type corner 140 at the front end of the rear air duct shell 100, its end extending forward can be engaged with the slot at the rear end of the front air duct shell 100, thereby facilitating a tight connection between adjacent air duct shells 100. In addition, an “L”-shaped angle steel support 150 is provided inside the air duct housing 100 , and the angle steel support 150 plays a role in shaping and increasing the strength of the air duct housing 100 .

[0032] like Figure 3 and 4As shown, in this embodiment, the air duct housing 100 includes a first metal plate 110, a fiber reinforced calcium silicate board 120 and a second metal plate 130. The first metal plate 110 is arranged on the inner side of the fiber reinforced calcium silicate board 120, and the second metal plate is arranged on the outer side of the fiber reinforced calcium silicate board. A high temperature resistant adhesive layer is provided between the first metal plate 110 and the fiber reinforced calcium silicate board 120, and between the fiber reinforced calcium silicate board 120 and the second metal plate. The second metal plate 130 is arranged on the outer side of the fiber reinforced calcium silicate board 120. In this embodiment, the first metal plate 110 is specifically a galvanized steel plate, the fiber reinforced calcium silicate board 120 is specifically a basalt fiber reinforced calcium silicate board 120, and the second metal plate 130 is specifically a galvanized steel plate, wherein the high temperature resistant adhesive layer is used to connect the fiber reinforced calcium silicate board 120 with the first metal plate 110 and the second metal plate, and the high temperature resistant adhesive layer is specifically a high temperature resistant high temperature resistant adhesive layer, which can meet the national fire resistance limit standards.

[0033] It is worth mentioning that basalt fiber is a high-performance material with natural basalt as the main raw material. After natural basalt is melted at 1450-1500℃, it is drawn at high speed through a platinum-rhodium alloy drawing plate to form a continuous fiber. The color of basalt fiber is generally brown and has a metallic luster. Specifically, basalt fiber is composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide and titanium dioxide. It has many excellent properties such as high strength, electrical insulation, corrosion resistance, high temperature resistance and aging resistance. Moreover, basalt fiber has good compatibility with the environment and does not produce secondary pollution. Therefore, it is a veritable green high-performance new environmentally friendly material. Moreover, basalt fiber, as an amorphous inorganic silicate material, has the advantages of short production period, simple process, no industrial wastewater, waste gas generation and high added value. Furthermore, in the field of construction, basalt fiber can be used to strengthen concrete structures and improve the seismic resistance of buildings; in the field of aerospace, due to its light weight and high strength, basalt fiber is also used to manufacture aircraft parts.

[0034] In this embodiment, the thickness of the first metal plate 110 is specifically in the range of 0.5 mm to 1.2 mm, the thickness of the fiber reinforced calcium silicate board 120 is specifically in the range of 5 mm to 12 mm, and the thickness of the second metal plate 130 is specifically in the range of 0.25 mm to 0.5 mm.

[0035] Specifically, the working principle and process of the utility model are:

[0036] By using the fiber-reinforced calcium silicate board 120 as the main material of the air duct housing 100, the effect of reducing the use cost can be achieved, and the energy loss and noise can be reduced during ventilation. Specifically, compared with the fire duct made of metal as the main material, the basalt fiber metal composite pipe that can reduce consumption and noise uses the fiber-reinforced calcium silicate board 120 as the main material, so it can reduce the use cost of the new air duct. In addition, the fiber-reinforced calcium silicate board 120 has a lower thermal conductivity and better sound insulation performance than metal materials, so it can reduce energy loss and reduce noise during ventilation.

[0037] In addition, the basalt fiber metal composite pipe that can reduce consumption and noise includes a first metal plate 110, a fiber reinforced calcium silicate board 120 and a second metal plate 130. The first metal plate 110 and the second metal plate 130 can realize the ventilation and other functions of the existing fire duct, and the fiber reinforced calcium silicate board 120 can be used to improve the fire resistance and thermal insulation of the fire duct, so as to meet the requirements of the fire resistance limit. Therefore, there is no need to install fireproof wrapping and other measures to improve the aesthetics of the fire duct and reduce space occupancy. The basalt fiber metal composite pipe that can reduce consumption and noise is easy to install and has a generous appearance. When used in air conditioning ventilation, fire ventilation and other systems, it can reduce energy consumption and reduce costs. In addition, compared with metal materials, fiber reinforced calcium silicate boards have lower thermal conductivity and better sound insulation performance, so they can reduce noise during ventilation.

All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
