Embodiment Construction

[0018] Refer to attached figure 1 , The optical fiber drawing cooling system is composed of static electricity removal device, cooling pipe body 6, cooling water pipe, gas pipe, cooling water circulation device and so on.

[0019] Static removal device: The static removal device is composed of static eliminator 1 and static transfer parts. Above the cooling pipe body 6, a static eliminator 1 is installed to alternately generate positive and negative ions to eliminate the static electricity generated before the optical fiber enters the cooling pipe body 6; Under normal circumstances, the optical fiber shakes seriously. At this time, the bare optical fiber 2 and the cooling tube body 6 generate static electricity due to contact friction, and the static electricity transfer part collects the generated static electricity and releases it to the ground. The static eliminator adopts the commercially available SFM300 high-performance miniature static eliminator. The static electricit...

A structure of the optical fiber drawing cooling system consists of an antistatic device, a cooling tube body, a cooling water pipe, a gas pipeline and a cooling water circulation device, wherein the antistatic device consists of a static eliminator and a static transferring component; the cooling tube body is provided with an inner cavity which is suitable for passing through the optical fiber, and the outside of the inner cavity is provided with the cooling water pipe and a gas injection channel of cooling gas; an upper mouth and a lower mouth of the cooling tube body are provided with drain plugs with variable apertures; the cooling water pipe is arranged on the outside of the inner cavity of the cooling tube body; the cooling water circulation device comprises a cooling water storage tank, a cooling water pump and a refrigerator; and the gas injection channel of the cooling gas is positioned on the lateral part of the cooling tube body, communicated with the inner cavity of the cooling tube body, and is distributed on the periphery of the inner cavity.

Description

technical field [0001] The optical fiber drawing cooling system of the invention relates to a bare fiber cooling system in the single-mode optical fiber drawing process, which is used for reducing the temperature of the optical fiber before coating, and is suitable for improving the curing performance of the optical fiber. An optical fiber drawing cooling system that makes single-mode optical fiber suitable for high-speed, large-capacity, and long-distance optical fiber communication systems. Background technique [0002] In the whole production process of optical fiber, the first step is to melt the optical fiber preform: the optical fiber preform is placed in the heating furnace of the wire drawing device, and after melting into a fluid state, it is cooled, coated and solidified, and then the wire is taken up. , become a semi-finished fiber. When the optical fiber is just out of the furnace, the temperature is high, and the prerequisite for optical fiber coating protectio...
