[0001] The present application relates to the technical field of aerogel fabric production equipment, and specifically to a hot air drying equipment for aerogel fabric production. Background Art

[0002] Hot air drying is a critical step in the production of aerogel fabrics. It effectively removes moisture absorbed by the fabric during stretching, thereby fixing its shape and improving the material's strength and durability. By controlling the temperature and humidity of the hot air, the aerogel's microstructure is preserved during the drying process, thereby improving its thermal insulation and breathability, and ensuring the quality and performance of the final product.

The hot air supply unit is used to dry the reinforcing fiber to ensure its dryness before production; the condensation hood directly condenses the hot air, and then flows into the water tank for water recovery; the whole is connected by bolts for easy later inspection and maintenance.

[0004] Existing hot air drying devices for aerogel fabrics usually adopt a method of heating air and then using a fan to blow hot air toward the fabric to evaporate the water vapor on the surface of the moist fabric to achieve the purpose of drying. However, during the process of hot air drying the fabric, there is still a problem that the hot air lacks guidance, resulting in local drying of the fabric, and the hot air cannot be evenly distributed on the surface of the fabric, which affects the drying effect of the aerogel fabric. In addition, the water vapor evaporated from the surface of the aerogel fabric is not easy to be discharged immediately, causing the water vapor to gather in the box, making the drying time required longer.

[0005] Therefore, it is necessary to provide a hot air drying equipment for aerogel fabric production to solve the above problems.

[0006] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Utility Model Content

[0039] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0041] See also Figure 1-6 , the embodiment provided by the utility model:

[0042] A hot air drying device for producing aerogel fabrics, comprising a frame 3 and a drying box 1 mounted on the frame 3, a feed port 2 being provided on one side wall of the drying box 1, a discharge port being provided on the other side wall of the drying box 1, and a transmission component 4 being fixedly mounted on the side wall of the frame 3;

[0043] The aerogel fabric to be dried is fed into the feed port 2 , passes through the transmission component 4 on the frame 3 , and is discharged from the box through the discharge port. The aerogel fabric is dried during the transportation process of the transmission component 4 .

[0044] The transmission assembly 4 includes a mounting plate 41 and a transmission roller 42. The mounting plates 41 are fixedly mounted on both side walls of the frame 3. Both sides of the mounting plate 41 are rotatably connected to the transmission rollers 42 through bearing seats. The two transmission rollers 42 rotate on both sides of the mounting plate 41 to transmit the aerogel fabric entering the drying box 1 to facilitate the sliding of the aerogel fabric inside the drying box 1.

[0045] A blowing assembly 5 is provided above and below the transmission assembly 4. The blowing assembly 5 is fixedly mounted on the top and bottom of the frame 3 by a lifting assembly 6 and is located inside the drying box 1. The blowing assembly 5 includes a blowing plate 51, a first air duct 52 and a second air duct 53. Both sides of the blowing plate 51 are fixedly mounted on the top and bottom of the frame 3 by lifting assemblies 6 respectively. A plurality of second air ducts 53 are fixedly mounted on the bottom surface of the blowing plate 51 above the transmission assembly 4 and the middle of the top surface of the blowing plate 51 below the transmission assembly 4 respectively. The plurality of second air ducts 53 are arranged vertically and equidistantly. A plurality of first air ducts 52 are symmetrically arranged on the bottom surface of the blowing plate 51 above the transmission assembly 4 and the top surface of the blowing plate 51 below the transmission assembly 4 with the axis of the plurality of second air ducts 53 as the axis. The plurality of first air ducts 52 are bent and inclined to both sides of the blowing plate 51 respectively;

[0046] In order to facilitate better hot air drying treatment on the surface of the aerogel fabric, blowing plates 51 are provided on both sides of the aerogel fabric to be able to blow hot air on both sides to improve drying efficiency. At the same time, since the first air duct 52 is arranged vertically and the second air duct 53 is inclined to both sides, the hot air acting on the aerogel fabric can be blown from the middle to both sides respectively, and the water vapor evaporated on the aerogel fabric can be blown to both sides at the first time to facilitate the collection of water vapor. At the same time, the second air duct 53 is arranged more densely the closer to the first air duct 52, so that the air outlet of each second air duct 53 can be uniform, thereby ensuring that the hot air blown to the aerogel fabric is blown out evenly, so as to improve the drying effect of the aerogel fabric and avoid local moisture and local drying.

[0047] Furthermore, air guide plates 54 are fixedly installed on both sides of the blowing plate 51 by screws. The air guide plates 54 are arranged at an angle. By adding the air guide plates 54, the hot air blowing toward the aerogel fabric can be converged, thereby speeding up the drying time of the aerogel fabric.

[0048] An air inlet duct 55 is fixedly installed on the back side of the blowing plate 51 away from the first air duct 52. An air trough is opened inside the blowing plate 51, and the air inlet duct 55 is respectively connected to the multiple first air ducts 52 and the second air duct 53 through the air trough; the air inlet duct 55 is connected to the device or equipment that can discharge hot air, so that the hot air required for drying can be discharged through the air inlet duct 55, and then the hot air can be discharged from the multiple first air ducts 52 and the second air duct 53 after passing through the air trough.

[0049] It is worth noting that the lifting assembly 6 includes a fixing frame 61, a mounting frame 62 and an electric push rod 63. The top and bottom of the frame 3 are respectively fixed with the fixing frame 61 by screws. The telescopic shaft of the electric push rod 63 is fixed to the blowing plate 51 by the mounting frame 62 and the bolts. The bottom of the electric push rod 63 is respectively fixed to the fixing frame 61. The distance from the blowing plate 51 to the aerogel fabric is controlled by extending or shortening the telescopic shaft of the electric push rod 63, so that the height of the blowing plate 51 can be adjusted according to the aerogel fabric of different thicknesses to adapt to aerogel fabrics of different thicknesses.

[0050] The side walls on both sides of the frame 3 are respectively fixedly installed with collection components 7 for collecting water vapor. The collection component 7 includes a collection plate 71 and a water cooling mechanism. The bottom inner side of the collection plate 71 is surrounded by a surrounding plate 74 to form a collection tank 75. The interior of the collection plate 71 is provided with a water cooling mechanism. The water cooling mechanism includes a water tank 77, a water inlet pipe 72 and a water outlet pipe 73. The top surface of the collection plate 71 is fixedly installed with a water inlet pipe 72. The interior of the collection plate 71 is provided with a water tank 77. The bottom side wall of the collection plate 71 is fixedly installed with a water outlet pipe 73. The water inlet pipe 72 is connected to the water outlet pipe 73 through the water tank 77. The side walls on both sides of the water tank 77 are respectively fixedly connected with partitions 78, and the side walls on both sides of the corresponding partitions 78 away from the water tank 77 are provided with gaps for cooling water to pass through.

[0051] When the water vapor is blown toward both sides of the rack 3 by the second air duct 53, the side wall temperature of the collecting plate 71 is lowered by the water cooling mechanism. When the water vapor contacts the lower collecting plate 71, it condenses into small water droplets on the side wall of the collecting plate 71, changing the gas state into liquid. Finally, the small water droplets are collected by the collecting groove 75 on the bottom of the collecting plate 71 and finally discharged from the interior of the box through the water collecting pipe 76, thereby achieving the purpose of quickly discharging the water vapor.

[0052] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
