Background technique
Optical fiber has the characteristics that loss low, bandwidth, strong antijamming capability, is widely used in the fields such as electronics, communication.
There are many method of optical fiber preform to manufacture optical fiber, mainly have at present: chemical vapor deposition method, PCVD (Plasma Chemical Vapor Deposition)
With axial vapor deposition method etc..However, prefabricated rods will be first made at high temperature, then in high temperature furnace with any method
Heating softening, pulls into long filament, then coated, plastic sleeve, becomes optical fibre core.Existing optical fiber prefabricating forming furnace calandria damage
When, it needs equal furnace body temperatures to drop to after certain value and carries out integral demounting again and reinstall, furnace body cooling rate is slow, affects furnace body
Normal use, working efficiency is low.Moreover, existing optical fiber prefabricating forming furnace furnace roof easily collapses, the quality of product is affected, is dropped
Low qualification rate.
Utility model content
The purpose of this utility model is to provide for a kind of optical fiber prefabricating forming furnace, makes it that can quickly and easily replace fever
Body, furnace roof are not easy to collapse, and extend heater service life, and burner hearth is scrapped caused by avoiding because of heater damage and therefore maintenance is made

To solve the above problems, the utility model provides a kind of optical fiber prefabricating forming furnace, including furnace body, heater and corundum
Crossbeam, the furnace body inside be equipped with insulating layer, the insulating layer be equipped with three layers, be followed successively by from outside to inside outside insulating layer,
Intermediate insulating layer, inside insulating layer, furnace interior are equipped with heater, and heater is mounted on the inside in four faces of furnace body, furnace
Copper bar is installed, the heater is made of U-shaped fever end and L-type cold end, and the end of cold end is equipped with sprayed aluminum layer, hair on body
The cold end of hot body connects band connection by aluminium, and aluminium connecting band is connect with copper bar, and copper bar is fixed on furnace body, is equipped on heater
Heater fixture, furnace body top are equipped with stainless steel upper cover, are equipped with fiber column, furnace body top half at four angles of furnace interior
Inside insulating layer and intermediate insulating layer between corundum crossbeam is installed.
There are four sunpender anchoring pieces for installation in the stainless steel upper cover.
There are two the corundum crossbeam installations, is located at the left and right sides.
By adopting such a design, the utility model at least has the following advantages:
1, rationally, heater is fixed by heater fixture for the furnace structure design of the utility model, and heater needs are torn open
When unloading replacement, aluminium connecting band to be unclamped, is directly pulled out from furnace roof portion heater, disassembly is simple, and it is easy for installation, it is not necessarily to
Entire burner hearth is disassembled after equal heaters are cooling, has saved replacing construction.
2, quadrangle increases fiber column in furnace body, effectively enhances the intensity of furnace roof, prevents from collapsing.
3, furnace roof installs four sunpender anchoring pieces additional, and furnace roof stainless steel upper cover is fixed on anchoring piece top, lifts furnace roof, prevents
It collapses.
4, corundum crossbeam is installed between the inside insulating layer and intermediate insulating layer of furnace body top half, can prevents from collapsing
It collapses.
