Embodiment three:

[0037] Reference Figure 7 To distinguish it from Example 1, this example provides another implementation scheme: the ventilation support pipe 11 in this example is a straight pipe instead of the curved pipe in Example 1.

[0038] Working principle: First, insert the quartz rod into the feed hole 309 and insert the bottom of the quartz rod into the through hole 5 at the top of the outer bin 4 corresponding to the feed hole 309.

After entering the next connected hollow tube 14, under the action of the coolant, the temperature inside the lower connected hollow tube 14 is lower, and then the quartz fiber can be cooled and shaped. At the same time, inert gas is introduced into the gas collecting hood 13 outside the outer warehouse 4, and the inert gas enters the inner gas collecting hood 13. The inert gas enters the interior of the ventilation support tube 11 through the inner gas collecting hood 13, and the inert gas is filled into the interior of the hollow column 10 through the ventilation support tube 11, and then the hollow column 10 can be pushed up. After the hollow column 10 is pushed up, the outer jacket 8 can be pushed up. After the outer jacket 8 is pushed up, the heat generating plate 7 can be pushed up, and then A certain distance is created between the ventilation support tube 11 and the hollow column 10, and the bottom of the ventilation support tube 11 passes between the outer bin 4 and the inner bin 6, and there is a cooling liquid between the outer bin 4 and the inner bin 6 that can reduce the temperature. The inert gas introduced into the inner bin 6 is at room temperature from the outside, and the inert gas temperature inside the ventilation support tube 11 can be kept low with the cooling liquid. Therefore, the temperature between the hollow column 10 and the ventilation support tube 11 can be kept low to avoid being in a high temperature environment for a long time. The suspension of the outer jacket 8 can prevent the ventilation support tube 11 and the heat generating device from being burned or melted, thereby improving the service life of the ventilation support tube 11, i.e., the support of the heat generating device, and further improving the service life of the heat generating device.
