Abstract
The utility model relates to a practice thrift cooling device of fiber drawing helium use amount, the tin liquid cooler comprises a cooling pipe. It still includes two exhaust tubes, gas -supply pipe, three way connection and negative pressure air exhaust device characterized in that, the one end of two exhaust tubes set up relatively on the lateral wall of cooling tube and with the cooling tube in feed through, the other end of two exhaust tubes is connected with three way connection respectively, negative pressure air exhaust device passes through the gas -supply pipe and is connected with three way connection. The utility model has the advantages of the helium use amount can be reduced and optic fibre manufacturing cost is reduceed.
Description
Technical field
The utility model relates to a kind of refrigerating unit of fibre-optical drawing, particularly relates to a kind of refrigerating unit saving fibre-optical drawing helium usage quantity.
Background technology
In current fiber draw process, after optical fiber goes out fiber drawing furnace, optical fiber cannot fully be cooled, and causes fibre coating abnormal; In order to stable fiber coating quality, the method of usual employing is connect a cooling tube in the lower port of wire drawing, fiber perpendicular passes into cooling tube downwards, from the lower end of cooling tube to passing into cooling helium, owing to bringing a large amount of heats into when optical fiber enters cooling tube, helium from bottom to top cools optical fiber, and optical fiber be made to cool thoroughly, need to input a lot of helium to take away these heats to cooling tube, and the use of a large amount of helium just considerably increases the cost of optical fiber production.
Summary of the invention
For above-mentioned shortcoming, the purpose of this utility model is to provide a kind of device that can reduce the saving fibre-optical drawing helium usage quantity of helium usage quantity and attenuating optical fiber production cost.
Technology contents of the present utility model is: a kind of device saving fibre-optical drawing helium usage quantity, comprises cooling tube; It is characterized by it and also comprise two extraction pipes, pneumatic tube, Y-junction and negative pressure ventilation device; The sidewall that one end of two extraction pipes is oppositely arranged on cooling tube is communicated with in cooling tube, and the other end of two extraction pipes is connected with Y-junction respectively, and negative pressure ventilation device is connected with Y-junction by pneumatic tube.
The utility model is compared with prior art advantageously: in drawing process, extract the gas in a certain amount of cooling tube by negative pressure ventilation device, accelerate the helium flow general character in cooling tube on the one hand, on the other hand owing to directly entering also cold pipe under the awfully hot state of optical fiber, a large amount of heats can also be taken away when this is the work of negative pressure ventilation device, thus the temperature reduced in helium gas cooling pipe, decrease the usage quantity of helium, ensure that optical fiber does not need too many helium just can arrive technologic application temperature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of device saving fibre-optical drawing helium usage quantity, comprises cooling tube 1; It is characterized by it and also comprise two extraction pipes 2, pneumatic tube 3, Y-junction 4 and negative pressure ventilation device 5; The sidewall that one end of two extraction pipes 2 is oppositely arranged on cooling tube 1 is communicated with in cooling tube 1, and the other end of two extraction pipes 2 is connected with Y-junction 4 respectively, and negative pressure ventilation device 5 is connected with Y-junction 4 by pneumatic tube 3.
