(12) after the optical fiber is processed for the preset time, opening a third valve 43, starting a vacuum pump 41, and pumping the box body 11 to vacuum;

(13) opening the stop valve 52 to balance the air pressure in the tank;

(14) when the air pressure inside the box body 11 detected by the pressure sensor 8 is consistent with the ambient air pressure, the first linear driving member 133 is started, so that the output shaft of the first linear driving member 133 retracts, the output shaft of the first linear driving member 133 drives the clamping block 132, the clamping head 131 and the connecting block 136 to rotate towards the direction away from the box door 12, then the box door 12 is rotated, and the box body 11 is opened.

(15) Starting the second linear driving part 93, wherein an output shaft of the second linear driving part 93 extends outwards to enable the slope plate 92 to incline until the slope plate 92 and the top side surface of the fixing plate 91 are parallel to each other, and then pushing the trolley loaded with the optical fiber disc out of the box body 11 through the inclined fixing plate 91 and the slope plate 92;

(16) the second linear drive member 93 is activated and the output shaft of the second linear drive member 93 retracts, causing the ramp plate 92 assembly to rotate to the horizontal.

By opening the shutoff valve 52, since the gas in the housing 11 is communicated with the outside air through the air line 51, the pressure in the housing 11 can be equalized, and the optical fiber in the housing 11 can be taken out easily.

In this embodiment, in step (11), the ratio of the flow rates of the deuterium gas and the nitrogen gas entering the chamber 11 is calculated by:

setting deuterium gas proportioning flow rate mu_(D)Volume V_(D)Pressure P_(D)Nitrogen gas proportioning flow rate mu_(N)Volume V_(N)Pressure P_(N)Deuterium gas process proportioning concentration X%, first flowmeter 23 full-range flow v_(D)Second flow meter 33 full range flow v_(N)Vacuum pressure P in the pressure tank 11 when filling the mixed gas of deuterium and nitrogen₀Pressure P in the tank 11 at the end of filling the mixture of deuterium and nitrogen₁；

The calculation formula of the ratio flow of deuterium gas to nitrogen gas is as follows:

when the box body 11 is filled with mixed gas of deuterium and nitrogen, the ratio of the proportioning flow of deuterium and nitrogen is equal to the ratio of the filled volume and the ratio of the filled pressure.

Since the interior of the housing 11 is not absolutely evacuated before mixing, there is a residual gas, and the larger the volume of the housing 11 is, the lower the tolerable degree of vacuum is, the more gas remains during vacuum replacement, the greater the influence on the concentration of deuterium after mixing the gas is, and the ideal state isWhen the interior of the box body 11 is vacuumized and replaced in the step (9), if the vacuumizing pressure P is adopted₀When the absolute pressure reaches 0, no residual gas is present in the chamber 11, but the pressure receiving capacity of the chamber 11 and the performance of the vacuum pump 41 affect the performance of the chamber 11, and the absolute vacuum cannot be achieved in the chamber 11 during evacuation replacement, so the effect of residual gas on the concentration of deuterium after mixing is subtracted when calculating the ratio of deuterium to nitrogen. Filling the mixed gas of deuterium and nitrogen into the box body 11 according to the ratio flow of deuterium and nitrogen calculated by the formula in the step (11) until the process treatment pressure P is reached₁Then, the concentration of deuterium in the box 11 can be accurately controlled to be X% of the process proportioning concentration set by an operator.

In this embodiment, the optical fiber deuterium treatment process further includes the following steps:

when the pressure sensor 8 detects that the internal gas pressure of the box 11 is reduced and exceeds the consumption range allowed by the process, the first valve 24 and the second valve 34 are opened, the first flow meter 23 and the second flow meter 33 supplement the mixed gas of deuterium and nitrogen according to the deuterium process mixture concentration X%, and when the box 11 supplements the mixed gas of deuterium and nitrogen, the deuterium and nitrogen mixture concentration is calculated according to the following formula:

the deuterium and nitrogen are mixed and enter the process treatment stage, the process treatment stage is influenced by the quality of the optical fiber product, the deuterium inside the box body 11 can be consumed, and the consumption can be compensated by supplementing the deuterium and nitrogen into the box body 11.

In this embodiment, the method further includes the step of (16) opening the fifth valve 16 and the sixth valve 17 of another box assembly 1 after processing the optical fiber in one box 11, and processing the optical fiber in the next box assembly 1.

When the optical fiber in one box body 11 is taken out, the optical fiber in another box body 11 can be processed by using the time, so that the box bodies 11 can be used independently or in combination; the pressure of the deuterium gas can be adjusted according to the requirement, so that the pressure of the deuterium gas meets the process requirement; the concentration of deuterium can be set as required, the proportion of deuterium and nitrogen is controllable, the gas mixing precision is guaranteed, and the gas purchase cost is reduced.
