The tops of the uprights 5 and risers 6 are connected to the upper surface of the upper ring body 8. At least two outer crossbars 9 are provided at the outer ends of the uprights 5 and risers 6. The outer crossbars 9 are connected to the inner wall of the tank 1. Several inner crossbars 10 are arranged radially on the inner side of the upper ring body 8. The inner crossbars 10 are all connected to the central seat 11. A bearing sleeve 12 is coaxially provided on the central seat 11. Several air outlet holes 701 are opened on the lower surface of the air outlet annular pipe 7. The top of the riser 6 is inserted into the bottom of the air inlet pipe 3. The mixing mechanism includes a motor 13, a main shaft 14, a first high-speed mixing disc 15, and a second high-speed mixing disc 16. The motor 13 is mounted on the upper surface of the tank 1 via a motor 13 mount. The output shaft of the motor 13 is connected to the top of the main shaft 14 via a coupling. The main shaft 14 is rotatably coupled with a bearing platform. The lower part of the main shaft 14 is provided with two first high-speed mixing discs 15 and second high-speed mixing discs 16. Both the first high-speed mixing discs 15 and second high-speed mixing discs 16 are rotatably mounted inside the tank 1.

[0016] Installation method and operating principle: First, assemble the aeration frame, connecting multiple uprights 5 and one riser 6 to the air outlet annular pipe 7 and the upper ring body 8. The riser 6 and the air outlet annular pipe 7 are internally interconnected. Several outer crossbars 9 are welded to the radial direction of the aeration frame along the outer edges of the riser 6 and the uprights 5. Several inner crossbars 10 are welded to the radial direction of the inner side of the upper ring body 8. The inner ends of the inner crossbars 10 are welded to the outer surface of the center seat 11. Then, the bearing sleeve 12 is installed at the center position of the center seat 11. The aeration frame is hoisted into the tank 1, and the outer crossbars 9 are welded to the inner wall of the tank 1. The top end of the main shaft 14 is connected to the output shaft of the motor 13 installed on the upper surface of the tank cover 2 via a coupling. Weld the air inlet pipe 3 to the tank cover 2, lift the tank cover 2, and place it above the tank body 1. Pass the main shaft 14 through the bearing sleeve 12. During descent, first install the second high-speed mixing disc 16 onto the main shaft 14. After the bottom of the main shaft 14 passes through the exhaust annular pipe 7, install the first high-speed mixing disc 15 at the bottom of the main shaft 14. Simultaneously, insert the air inlet pipe 3 into the top of the riser pipe 6, sealing the connection with a sealing ring. Cover the tank with the tank cover 2 and connect it to the tank body 1 via a flange. Installation personnel climb out through the manhole 17 to complete the installation. Before use, the air inlet port 4 is connected to the air compressor via a pipe. In use, the dry-mixed powder is fed into the tank 1 through one of the feed ports 18. Then, an appropriate amount of solvent (deionized water or ethanol) is fed into the tank 1 through the other feed port 18. The motor 13 is started, and the motor 13 drives the main shaft 14 to rotate, thereby driving the first high-speed mixing plate 15 and the second high-speed mixing plate 16 to rotate at high speed. At the same time, the air compressor is started, and the gas enters from the air inlet pipe 3, passes through the riser pipe 6 and the air outlet annular pipe 7, and exits from each air outlet 701 to aerate and mix the material. This utility model has a reasonable structure. An aeration frame is installed inside the tank body 1. The aeration frame is supported inside the tank body 1 by at least two layers of outer crossbars 9. The bottom air outlet annular pipe 7 is connected to the riser pipe 6. The top of the riser pipe 6 is inserted into the air inlet pipe 3. Thus, gas stirring can be achieved during the stirring process by two height stirring discs, which greatly improves the stirring effect and makes the agglomerates of gas phase silica form a uniform nano-network structure. This allows the opacifier particles to be better distributed in the silica network and the fibers to be better dispersed. At the same time, a center seat 11 is set on the inner side of the upper ring body 8 at the upper end of the aeration frame through the inner crossbar 10. The center seat 11 cooperates with the main shaft 14 through the bearing sleeve 12, which further improves the stability of the main shaft 14.
