Abstract
The present invention discloses a kind of fiber drawing furnace cooling tube helium collector, it is directly connected to mouth under fibre drawing furnace cooling tube, collects the helium being discharged from cooling tube and is collected while not influencing drawing process and product quality to helium.The upper end of collector is connected with mouth under cooling tube, is screwed, and optical fiber enters collector after cooling tube, and there is the channel that optical fiber passes through in the lower end of collector.This fiber drawing furnace cooling tube helium collector, is divided into left and right two parts, has seal groove among right part, avoid helium side leakage, and when cooling tube merges, collector also merges into an entirety.
Description
Technical field
The present invention relates to circulated helium reutilization technology fields, and in particular to the helium recovery technique of fiber drawing furnace cooling tube.
Background technique
Helium is inert gas, colourless under normal pressure and temperature, tasteless, nontoxic, non-combustible.It is that the mankind have found that critical-temperature is minimum
Substance, aobvious buff, is to be most difficult to liquefied gas when low pressure discharge, extremely inactive, cannot be burnt, also not fire-retardant, under normal pressure
Helium will not solidify when absolute zero.Derived from this class feature of helium, helium is very widely used on modern industry.Helium is in light
In fine manufacturing process, the protective gas that wire drawing stages use helium to heat and soften as optical wand utilizes the superconductivity and inertia of helium
The characteristic of gas, prevents optical wand from aoxidizing, and plays thermal conduction characteristic and saves energy consumption.It is right with the development and expansion of internal optical fiber industry
The requirement of helium is being continuously increased, and price is constantly fluctuating, since helium relies primarily on import, so the development of enterprise and at
Originally the restriction by importer, and then the recycling and reuse of helium are put forward new requirements.Corresponding research and development are also continuous
Progress in, the application for a patent for invention of this helium collector is also just come into being.The research and development of this helium collector are also gone through
The initial stage of very long a period of time is designed, and improves and the on-the-spot test in later period can adapt to more under the premise of guaranteeing the rate of recovery
Kind operating condition.
In the research and practice process to the method, the inventors found that：This helium collector internal junction
Structure complies fully with hydromechanical architectural characteristic, is a collector calculated by design with practical test, he has uniqueness
Internal structure external structure, this be also realize function the most important condition.
Summary of the invention
The present invention discloses a kind of fiber drawing furnace cooling tube helium collector, it is directly connected to mouth under fiber drawing furnace cooling tube, receives
The helium discharged in collection fiber drawing furnace cooling tube production collects helium while not influencing drawing process and product quality.It collects
Device is the same with cooling tube, is divided into left and right two parts and merges into a single whole when cooling tube works, and collector also merges into a single whole at this time,
The upper end of collector is connected with mouth under fiber drawing furnace cooling tube, and centre is collecting chamber, and there are optical fiber through hole, optical fiber after cooling in lower end
From there through.
1) a kind of fiber drawing furnace helium collector, it is characterised in that：It can be directly connected to mouth under fiber drawing furnace cooling tube, fiber drawing furnace
The helium being discharged in cooling tube production enters follow-up system by the collection port of collector two sides after collection.
2) a kind of fiber drawing furnace cooling tube helium collector, it is characterised in that：The pore size of the cooling pipe end of fiber drawing furnace is connected,
With the method at fixed and sealing, the interface of collector outlet end and interface structure and size at pumping.
3) a kind of fiber drawing furnace cooling tube helium collector, it is characterised in that：The position of collector helium collection port, size and
Connection type.
4) a kind of fiber drawing furnace cooling tube helium collector, it is characterised in that：The structure of collector lower part optical fiber through hole, position
It sets and size.
5) a kind of fiber drawing furnace cooling tube helium collector, it is characterised in that：Collector is divided into left and right two parts, between the two
Contact, sealing means.
Above-mentioned technical proposal can be seen that since the embodiment of the present invention uses the method integrated theory with practice,
The actual application ability of design is very strong, and is optimized in the application, is a qualification that industrialized production may be implemented
Product.
Advantages of the present invention：
The present invention is a kind of fiber drawing furnace cooling tube helium collector, can be received from fiber drawing furnace cooling tube by this collector
The helium for collecting higher purity realizes the higher rate of recovery, improves economic value for cleaning equipment.
