Embodiment

[0018] This embodiment is a fifty-six-hole double-crucible wire drawing system for drawing multi-component glass optical fibers, which consists of a feeding device, a melting material device, a temperature control device and a winding device. Such as figure 1 As shown, the core material premelter 1 and the skin material premelter 2 in the shape of a Z-shaped pipe are made of platinum and are respectively placed on both sides above the double crucible. of the liquid outlet. The upper layer 3 of the double crucible is the core material crucible body, and the lower layer 5 is the leather material crucible body. Both the upper and lower crucible bodies are fixed with a corrugated acute-angle stepped bubble-removing structure 4, and several reinforcing strips 6 are installed between the leaking plates of the crucible body. Depend on figure 2 It can be seen that the sides of the core material crucible body 3 and the leather material crucible body 5 are provided with overflow hol...

Abstract

A multi-hole dual-crucible drawing system for drawing multi-component optical glass fibre is composed of feeding unit with premelting units for core material and surface material, melting unit with isolated two crucibles with a discharging hopper connected to both crucibles, temp controller, air bubble dischager and winder. Its advantages are high uniformity and transparency of optical fibre, and simple structure.

Description

technical field [0001] The invention relates to a double-crucible wire-drawing system for drawing multi-component glass optical fibers, in particular to a porous double-crucible for drawing glass optical fibers with improved structure, which belongs to the technical field of glass fiber manufacturing. Background technique [0002] The multi-component glass optical fiber is composed of high and low refractive index multi-component glass as the core layer and the skin layer. When the light enters the optical fiber at a certain angle, multiple total reflections occur at the interface between the core and the skin, so that the light energy is transmitted from one end of the optical fiber to the other end to realize light transmission. At present, multi-component glass optical fibers have been widely used in medical equipment, instrument lighting, optical instruments, power engineering and other industries, and their manufacturing processes include rod-tube method and double-cruc...
