Although these non-metallic materials have certain advantages in durability and thermal insulation, their surface strength is relatively low and they are easily affected by external environmental impact and deformed. Moreover, the surface of non-metallic materials is relatively rough and easy to accumulate dust. The accumulation of dust may also become a breeding ground for bacteria and mold, thereby causing further pollution to the indoor air.

DETAILED DESCRIPTION

[0019] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0020] like Figure 1-4 As shown, an inorganic veneer floating bead fire-resistant insulation board air duct includes an air duct body 1, the air duct body 1 is provided with a windproof cover 2, the air duct body 1 is composed of multiple floating bead fire-resistant insulation boards 4 and a reinforcement component, the outer surface of the floating bead fire-resistant insulation board 4 is provided with an inorganic veneer coating; the reinforcement component includes a floating bead fire-resistant insulation board 4 and a fixing frame 7, the surface of the floating bead fire-resistant insulation board 4 is provided with a threaded hole 6, the fixing frame 7 is provided with a connecting hole 8 matching the threaded hole 6, the screw 9 passes through the connecting hole 8 and is connected to the threaded hole 6 for fixation, and the air duct body 1 has a splicing part; the fixing frame 7 is L-shaped, and the fixing frame 7 is made of lightweight aluminum alloy.

[0021] The air duct body 1 is used to transport indoor air to the outdoors through the wind shield 2; the air duct is generally installed in public areas and high-risk areas, and the fire-resistant and heat-insulating effect of the air duct is particularly important. The air duct body 1 is composed of four floating bead fire-resistant insulation boards 4. To enhance the fire-resistant and heat-insulating performance of the air duct body 1, a strong glue is applied to the oblique mouth of the floating bead fire-resistant insulation board 4 during assembly. On the one hand, it can be fixed, and on the other hand, it can prevent the air entering the air duct 5 from leaking from the oblique mouth gap. In order to make the air duct have more outstanding fire resistance and durability, an inorganic veneer coating is added to the outer surface of the floating bead fire-resistant insulation board 4. Layer 3 is realized; since the bevel of the floating bead fire-resistant insulation board 4 is only applied with strong glue for simple fixation, this will be very unreliable. In order to further strengthen the strength of the air duct main body 1, a reinforcing component is added. The reinforcing component includes several internal threaded holes 6 on the surface of the floating bead fire-resistant insulation board 4, which are matched with several connecting holes 8 on the fixing frame 7. The fixing frame 7 is L-shaped. The fixing frame 7 uses light weight, corrosion-resistant, high-strength materials such as aluminum alloy and titanium alloy. The fixing frame 7 is connected to the air duct main body 1 composed of four floating bead fire-resistant insulation boards 4 by a screw 9 to increase the overall strength of the air duct.

[0022] The splicing part of the air duct body 1 includes a mounting groove 10 on the surface of the floating bead fire-resistant insulation board 4, a mounting hole 11 and a connecting plate 12 that matches the mounting groove 10, and the connecting plate 12 is provided with a fastening hole 13 that matches the mounting hole 11. The screw 9 is used to connect the fastening hole 13 with the mounting hole 11 for splicing.

[0023] like Figure 5 As shown, since the lengths of the air ducts used in different environments are different, an assembly part is added to the air duct body 1 so that the air duct body 1 can be spliced. A mounting groove 10 is provided on the surface of the floating bead fire-resistant insulation board 4, and a mounting hole 11 is provided in the mounting groove 10. When splicing, strong glue is applied to the connection of the air duct body 1. On the one hand, simple fixation can be performed, and on the other hand, the air entering the air duct 5 can be prevented from leaking from the gap at the connection. Then the connecting plate 12 is placed inside the mounting groove 10 and spliced and fixed with the screw 9 to achieve the length required for actual use.

[0024] The air outlet 14 of the wind shield 2 is arranged downward, and a detachable and replaceable filter is arranged in the air outlet 14 .

[0025] The existing air duct exhaust vents are all straight-through. In extremely windy weather, outdoor air will flow back into the room along the air duct. A wind shield 2 is set at the air duct exhaust vent to solve this problem. According to the knowledge learned, when the ventilation duct gradually becomes smaller, the gas flow rate will increase. The speed and pressure of the fluid in the duct are inversely proportional. The increased wind speed helps to more effectively transport air to farther areas, such as Figure 6As shown, the air inlet of the wind shield 2 is larger than the size of the exhaust outlet 14; the wind shield 2 is provided with a downward exhaust outlet 14 to prevent strong winds and rain and snow from entering the room along the air duct in extreme weather and affecting the indoor air quality; in order to prevent insects, birds, etc. from entering the air duct channel, a filter is provided at the exhaust outlet 14, and the filter is designed to be easy to remove and replace, which is convenient for regular maintenance, and ensures that the exhaust process will not cause poor ventilation due to the principle of filter clogging.

[0026] The use process of the inorganic veneer floating bead fire-resistant insulation board air duct of the utility model is as follows: four floating bead fire-resistant insulation boards are used to form the air duct, and then the air duct is reinforced with a fixing frame to increase the strength, and an inorganic veneer is added to the surface of the air duct to reduce surface dust generation; in order to use air ducts of different lengths in different environments, a splicing part is used to splice multiple air duct bodies to achieve the required length, and a windproof cover is set to transport air to a farther area. The windproof cover is provided with a detachable and replaceable filter to prevent insects, birds, etc. from entering the room through the air duct channel.

[0027] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art may make various modifications, additions, or substitute similar methods to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
