Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber drawing, in particular to an air flow stabilizing device for glass fiber production. Background Art

[0002] In the glass fiber production process, the airflow state first affects the cooling process of glass from liquid to fiber root. Unstable airflow (especially transverse airflow) can cause uneven fiber diameters or even breakage.

[0003] There is no air flow guide around the forming area of ​​the existing wire drawing equipment. In a short section close to the root of the wire and below it, the air pressure is relatively negative because the fiber movement speed is not fast. When the fiber moves downward at a very high speed, the nearby gas is also driven downward, and a positive pressure area is quickly formed in the fiber fan surface. Since the fibers will eventually be integrated into a bundle, the fibers move closer and closer to each other when they move downward, and the airflow is also pressed closer to each other, and the positive pressure becomes greater and greater, so that the positive pressure airflow here spreads horizontally to the surroundings, or blows back to the negative pressure area near the leak plate, which will inevitably form irregular turbulence and eddy currents on the fiber fan surface, making the operation difficult and affecting the product quality.

[0024] Example 1

[0025] like Figure 1 and Figure 2 As shown:

[0026] An air flow stabilizing device for glass fiber production includes a base 1, an air outlet channel is arranged inside the base 1, a plurality of air outlets 11 connected to the air outlet channel and evenly arranged are opened at the bottom of the base 1, and an air inlet pipe 12 connected to the air outlet channel is arranged on the side of the base 1.

[0027] The base 1 is installed at the bottom of the side of the drain plate 2, and a connecting plate 13 is installed on the side of the base 1. A plug-in port 131 is provided on the connecting plate 13. A plug-in board 21 corresponding to the plug-in port 131 is installed near the base 1 of the drain plate 2. The base 1 and the drain plate 2 are detachably connected through the plug-in board 21 and the plug-in port 131.

[0028] A limit plate 14 is installed at the outer end of the plug board 21 , and the distance between the two limit plates 14 is consistent with the width of the drain plate 2 .

[0029] The air inlet pipe 12 is arranged on the side of the base 1 away from the leak plate 2, a wind pressure sensor 3 is installed at the bottom of the base 1, the air inlet pipe 12 is connected to a gas cylinder, and the wind pressure sensor 3 is electrically connected to the valve on the gas cylinder.

[0030] It is also possible to install a pressure gauge at the air inlet pipe 12 to monitor the pressure at the air inlet pipe 12 in real time and manually control the valves on gas supply equipment such as gas cylinders to facilitate operator control.

[0031] The surfaces of the base 1 and the air inlet pipe 12 are coated with a high temperature resistant coating made of high temperature resistant paint, and the high temperature resistant paint is ceramic paint, silicate paint, phosphate paint, zinc-rich primer, fluorocarbon resin paint, heterocyclic polymer paint and silicone high temperature resistant paint.

[0032] Working principle: In the forming area below the leak plate 2 during wire drawing, the filament bundle 5 moves downward at a very high speed, and the nearby gas is also driven to move downward, and a positive pressure area is quickly formed in the filament bundle 5. Since the filament bundle 5 will eventually be integrated into a bundle, the fibers move closer to each other as they move downward, and the airflows are also pressed closer to each other. The probe of the wind pressure sensor 3 detects that the positive pressure is getting bigger and bigger. The wind pressure sensor 3 controls the valve of the gas cylinder to open, and the gas cylinder injects air into the air outlet duct through the air inlet pipe 12. The air flows out from the air outlet 11 and forms a wind curtain 4 in the forming area, so that the airflow flows in the longitudinal direction to reduce turbulence.

[0033] The utility model has a simple structure, and a vertical wind curtain is formed downward through the air outlet, so that the airflow in the forming area can be controlled, and the uneven thickness and breakage of the tow caused by the turbulent airflow at the table can be effectively improved, thereby improving the glass fiber drawing forming rate and quality.

However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
