Description
Technical field
The present invention relates to a kind of loose body optical fiber prefabricated rod preparation facilities, more particularly to a kind of preform of many blowtorch
OVD deposits preparation facilities.
Background technology
OVD techniques are a kind of processes in prepared by preform, i.e., outer vapour is as chemical deposition process：Outside
Vapor Deposition.The cardinal principle of this method is to spray high-purity vapour as raw material outside target rod by blowtorch（Usually
Silicon tetrachloride evaporates raw material）, the raw material at high temperature with O2Chemically reacted with steam, generate SiO2Fine particle, passes through heat
Swimming effect is deposited in target rod.Relative motion is carried out between blowtorch and target rod, so that SiO2Fine particle layer by layer deposition exists
Until reaching design weight in target rod, the intermediate products of preform are obtained：Loose body optical fiber prefabricated rod（Soot
Prefrom）.
Current loose body optical fiber prefabricated rod OVD deposition preparation facilities, including deposition casing, prefabricated fiber rod depositing branch
Frame, blowtorch, wind pushing box and exhaust column, prefabricated fiber rod depositing support are arranged in sediment box body, and two or three blowtorch are equidistant
It is arranged in below prefabricated fiber rod depositing support, fresh air inlet is provided with the side of wind pushing box, wind pushing box is arranged under deposition casing
Connected on side, the deposition casing below prefabricated fiber rod depositing support provided with an air intake circular hole with wind pushing box, in optical fiber prefabricating
Deposition casing above rod deposited stent is connected with exhaust column；Equipment is by blowtorch to being placed on prefabricated fiber rod depositing support
Target rod deposition high-purity sio2 granule, existing loose body optical fiber prefabricated rod OVD deposition preparation facilities is all using double blowtorch
Or three blowtorch, the sedimentation rate and efficiency of this kind of equipment be high.
The content of the invention
For disadvantages mentioned above, it is an object of the invention to provide a kind of sedimentation rate and the loosening body of many blowtorch of efficiency high
Preform OVD deposits preparation facilities.
The present invention technology contents be：The loose body optical fiber prefabricated rod OVD deposition preparation facilities of many blowtorch, including sediment box
Body, prefabricated fiber rod depositing support, blowtorch, wind pushing box and exhaust column；Wind pushing hole is provided with the side of wind pushing box；Wind pushing box is set
Below deposition casing, prefabricated fiber rod depositing support is arranged in sediment box body；It is characterized in that it also includes exhausting casing, mistake
Filter screen and exhausting diffusing laminar flow plate；5~15 blowtorch are arranged on prefabricated fiber rod depositing support；In exhausting diffusing laminar flow
Plate is provided with some air vents；The length connected with wind pushing box is provided with deposition casing below prefabricated fiber rod depositing support
Square fresh air inlet；Exhausting casing is arranged on above deposition casing, is set on the deposition casing above prefabricated fiber rod depositing support
There is a rectangle exhausting hole connected with wind chamber；Exhausting diffusing laminar flow plate is arranged in wind chamber body, above exhausting casing with
Exhaust column is connected；Screen pack is provided with wind pushing hole and fresh air inlet.
Found by studying, to improve loose body optical fiber prefabricated rod sedimentation rate and efficiency, exactly roll up blowtorch number
Amount, but it is due to the fresh air inlet of original deposition casing and exhausting hole is circular port, it carries out exhausting in sediment box body
When, the center wind speed that fresh air inlet and exhausting hole are corresponded to above prefabricated fiber rod depositing support is fast, and when from fresh air inlet
The position gradually increased with the centre distance in exhausting hole, wind speed is gradually reduced, and uniform negative pressure can not be formed in sediment box body,
Wind speed can not be made to obtain in sediment box body uniformly, so that the uniformity of the diameter of loose body optical fiber prefabricated rod prepared by many blowtorch
Difference, the unicity of internal cell structure can not ensure, product is scrapped also therefore just；And the present invention by deposition casing it is upper,
Lower end sets a rectangle fresh air inlet parallel with prefabricated fiber rod depositing support and exhausting hole respectively, and in the upper of deposition casing
Side is connected with a wind chamber, and an exhausting diffusing laminar flow plate is set in wind chamber, it is possible thereby to so that be formed in whole wind chamber
Uniform negative pressure, makes to the formation laminar flow at deserved rectangle exhausting hole above prefabricated fiber rod depositing support, so that whole
The wind speed passed through on preform on individual prefabricated fiber rod depositing support is uniform, so that in whole sediment box body, wind speed
Uniformly, the uniformity of the diameter of the loose body optical fiber prefabricated rod of many blowtorch preparations can be made good, interiors of products lattice structure is can guarantee that
Unicity.
The present invention is compared with prior art advantageously：It is pre- that the present invention improves loose body optical fiber by many blowtorch
Rod processed prepares sedimentation rate and efficiency high, and the uniformity of the diameter of loose body optical fiber prefabricated rod can be made good, can guarantee that in product
The unicity of portion's lattice structure.
