The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.
A sealing device for the tail handle of optical fiber preform rod, as shown in fig. 1-5, comprises a quartz tail tube 1 fixed on the rod hanging platform, the lower end of the quartz tail tube is generally used to hang the tail handle 13 part of the preform rod 12 through a rod hanging hook 11, usually, the preform rod is doped material mainly containing quartz, and the tail handle is made of quartz. A quartz assembly used for realizing sealing is sleeved in the diameter-changing area of the tail handle of the prefabricated rod. The sealing device provided by the invention achieves the sealing of the tail handle of the prefabricated rod when the tail handle enters the wire drawing furnace through the quartz assembly in the reducing area of the tail handle, ensures the stability of air flow in the wire drawing furnace, can avoid blow-by oxidation of the wire drawing furnace caused by the large reducing area of the tail handle of the prefabricated rod, and reduces the loss of a graphite piece of the wire drawing furnace, thereby improving the utilization rate of raw materials and reducing the production cost of optical fibers.
During the equipment, hang the quartzy tail pipe in hanging excellent platform through the tail pipe chuck earlier, then drop in prefabricated excellent afterbody reducing district to the prefabricated excellent tail handle of quartz ring cover, the rethread hanging excellent hook is with prefabricated excellent and place into quartzy tail pipe lower part inslot.
Increase quartzy semicircle ring (two semicircle ring involutes) on quartzy ring, make telescopic left lamella part and right lamella part down along all contactless prefabricated stick, place left lamella part and right lamella partial combination on quartzy ring at last, when normal wire drawing to tail-end rod, the sharp change of prefabricated stick afterbody diameter has been avoided to the sleeve, guarantees that the air current in the wire drawing stove is more stable. The sealing device has high reliability, good sealing performance and simple process.
The specific structure and composition are as follows:
the quartz assembly comprises a downwardly opening sleeve 2 having a plurality of quartz rings disposed within an open end of the sleeve, the sleeve being spaced from the preform by the quartz rings. The sleeve, the quartz tailpipe, the preform and the quartz rings are preferably arranged coaxially.
In an alternative embodiment, the quartz ring comprises a sleeved ring 3 and a split ring 14, the sleeved ring is of a whole ring structure, and the split ring is formed by assembling two half rings to form a ring structure. Before the prefabricated rod is hung on the quartz tail pipe, the prefabricated rod tail handle can be firstly sleeved with a required number of sleeving rings (whole rings) according to requirements, or a plurality of groups of assembling rings (semi-rings) can be simultaneously installed, and then the tail handle part is hung on the lower part of the quartz tail pipe through a hanging rod.
When the sleeve is assembled, the number of layers of the assembling rings (semi-rings) can be increased or decreased as required, and the sleeve is properly adjusted on the principle that the sleeve is not in contact with the prefabricated rod. The split mounting type structure with the quartz circular ring as the semi-ring is adopted, and the operation after the rod is hung can be facilitated. The number of the quartz circular rings and the quartz semi-rings is determined by the length of the reducing area of the tail handle, and the quartz circular rings and the quartz semi-rings are mainly used for preventing the quartz sleeve and the lower edge of the quartz sleeve from being connected with the prefabricated rod in a melting way in a wire drawing furnace.
It should be pointed out that the ring of assembling generally arranges at the lantern ring lower extreme (at least the top cover is equipped with a lantern ring), utilizes the whole ring structure of lantern ring, can play the effect of compressing tightly the ring of assembling of fixed downside, avoids assembling the ring and drops, highly suitable back when the quartz ring, assembles the sleeve and has accomplished the equipment of sealing device structure promptly. The sleeve covers the reducing area of the tail handle of the prefabricated rod, so that the sealing effect is achieved when the tail rod of the prefabricated rod enters the wire drawing furnace.
The sleeve comprises a left flap part 4 and a right flap part 5 which are assembled and fixed. In an optional embodiment, the right petal part is provided with a hook 6, the left petal part is provided with a hanging hole 7 corresponding to the hook of the right petal part, the hook of the right petal part is hung in the hanging hole of the left petal part, the two petal structures can be assembled into a sleeve, the operation is convenient, the implementation is convenient, and the sleeve is in an assembled structure, so that the installation of the internal quartz ring (assembled and replaced) is also convenient.
As a specific embodiment, the quartz tail tube may be fixed on the rod hanging platform 9 through the tail tube chuck 8, and an upper groove for fixing the tail tube chuck is disposed at the upper end of the quartz tail tube.
Similarly, the lower end of the quartz tail tube is provided with a lower groove 10 for fixing the tail handle of the prefabricated rod. The tail handle part of the prefabricated rod can be fixed in the lower groove at the lower part of the quartz tail pipe through a rod hanging hook, of course, the fixing can be carried out by adopting other structural forms in the prior art by a person skilled in the art, and only the prefabricated rod is fixed and hung.
The following provides a sealing method of a tail handle of an optical fiber preform, which comprises the following steps:
fixing a quartz tail pipe on the rod hanging platform through a tail pipe chuck;
fixing a tail handle of the prefabricated rod on a quartz tail pipe through a rod hanging hook;
sealing of the prefabricated rod tail handle in a wire drawing furnace is realized by arranging a quartz assembly, wherein the quartz assembly comprises a sleeve and a plurality of layers of quartz circular rings sleeved on the prefabricated rod tail handle;
through the quartz ring that increases suitable quantity, when guaranteeing that the sleeve covers prefabricated excellent reducing district, avoid sleeve and prefabricated excellent direct contact again.
In the device and the method, the outer diameter of the quartz assembly is matched with the diameter of the prefabricated rod, and the error between the outer diameter of the quartz assembly and the diameter of the prefabricated rod is within 3 mm. The diameter change between the quartz assembly and the prefabricated rod is small, and the stable airflow in the wire drawing furnace is ensured.
The tail handle sealing device of the optical fiber preform rod provided by the invention avoids the production hidden trouble caused by a larger diameter-changing area at the tail part of the preform rod through a reasonable structural design. Meanwhile, the pretreatment process of the preform is effectively reduced, the original tail handle does not need to be cut off, and then the tail pipe is butted for rod hanging and wire drawing, so that the production difficulty is reduced, and the cost is also reduced.
