Abstract
The utility model discloses a heating furnace body in an optical fiber wire drawing device, which relates to a furnace body for heating a wire drawing raw material in an optical fiber wire drawing process. The heating furnace body in the optical fiber wire drawing device consists of a furnace body, a heat preserving layer, an electric heating wire and a temperature sensor, wherein furnace covers are arranged on the upper part and the lower part of the furnace body respectively, and are provided with holes; each furnace cover is partitioned into two halves, and can be opened and closed; the upper furnace cover and the lower furnace cover are linked together through a coupled axle; and an air inlet tube is arranged on the lower part of the furnace body. During use of the heating furnace body, a raw material enters a hearth from the hole on the upper furnace cover, and a withdrawn optical fiber is led out of the hole of the lower furnace cover. The upper furnace cover and the lower furnace cover are arranged, so that the temperature in the hearth is relatively uniform and stable, and is easy to control. Moreover, during use, inert gases (such as nitrogen gas and the like) can be conveyed into the hearth through the air inlet tube, so that the raw material is prevented from being oxidized in a heating process and influencing the wire drawing quality. Inert gases can be used for keeping the temperature in the hearth uniform and preserving heat.
Description
Technical field
Heating furnace body in a kind of optic fibre drawing apparatus relates in the drawing optical fibers process, the body of heater that the wire drawing raw material is heated.
Background technology
Traditional drawing heating furnace is to be made up of body of heater, thermal insulation layer, nichrome wire and TP.Burner hearth is cylindrical, is used to up and down lead to.The shortcoming of this kind structure is inhomogeneous to the heating of raw material, and temperature is wayward, and raw material is prone to oxidation affects wire drawing quality.
The utility model content
The purpose of the utility model provides a kind of homogeneous heating, easy temperature control, and the protection raw material is difficult for the heating furnace body in the optic fibre drawing apparatus of oxidation.
Heating furnace body in a kind of optic fibre drawing apparatus is to be made up of body of heater, thermal insulation layer, nichrome wire and TP; The upper and lower bell that is equipped with respectively at body of heater has the hole on the bell; The bell branch is two halves, can folding; Upper and lower bell is joined together by couple axle; Inlet pipe is equipped with in the bottom of body of heater.
When this heating furnace body used, raw material got in the burner hearth from the hole on the last bell, and the optical fiber of pulling out comes out from the hole of following bell.Owing to installed upper and lower bell additional, the temperature in the burner hearth is more uniform and stable, and is easy to control.In addition, in use, also can in burner hearth, send into rare gas element (like nitrogen etc.), in case raw material oxidation in heat-processed influences the wire drawing quality through inlet pipe.Rare gas element also can keep the temperature in the burner hearth evenly to reach insulation.
