Abstract
The utility model discloses an air sealer of optical -fiber wiredrawing furnace, it includes seal assembly, is used for to prevent that seal assembly from prefabricating the spacing subassembly of having been taken when the stick rises, spacing subassembly including install in on wire drawing stove mount pad, connect in on the mount pad and adjustable position's depression bar, press when the depression bar puts down in seal assembly is last. This device utilizes spacing subassembly to play and prevents that prefabricated stick from reaching sealed lid with sealing filler and having taken the occurence of failure that causes the oxidation of wire drawing stove when mentioning, avoid the damage of the interior graphite spare of wire drawing stove, stopped the waste in man -hour that meaningless optic fibre loss and the oxidation of yin lasi stove led to the fact to direct, indirect improvement economy is imitated and is overflow.
Description
Technical field
This utility model is related to optical fiber producing apparatus, particularly to a kind of air sealer of optical-fiber wiredrawing furnace.
Background technology
It is to improve drawing optical fibers production efficiency to reduce downtime now, preform size does bigger and bigger, and length, diameter are all
Increasing, the single diameter fluctuation of the prefabricated rods of diameter 200mm is very big in the market, up to 20mm, for this diameter of production
Uneven prefabricated rods, the air seal method adopting now is to add an obturating cup in wire drawing fire door, in obturating cup inner preform week
Frontier fortress's upper gland packing, is then pushed down with closure again, causes fiber drawing furnace to aoxidize to prevent air from entering.For ensureing airtight and watertight padding
Elastic sealing cover can not be too heavy, but because preform diameter is again very uneven, and therefore in rod withdrawal, (optical wand heats up needs when turning around
Rod withdrawal, from dynamic circuit breaker fine or because certain reason artificially cuts off optical fiber when need rod withdrawal, need rod withdrawal at the end of drawing optical fibers ending) pole
Easily will lift as the airtight and watertight padding of sealing and closure, thus causing fiber drawing furnace to aoxidize.
Content of the invention
The purpose of this utility model is to provide a kind of sealing effectiveness guaranteeing fibre drawing furnace, can have under any circumstance
The prevention air of effect enters fiber drawing furnace, it is to avoid the air sealer of optical-fiber wiredrawing furnace of fiber drawing furnace oxidation.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of air sealer of optical-fiber wiredrawing furnace, and it wraps
Include black box, described black box includes being placed on described fiber drawing furnace and middle part offers the insert port mated with prefabricated rods
Obturating cup, be placed on described obturating cup and middle part offer the insert port mated with prefabricated rods closure, be filled in described close
Seal in the cavity that bowl and closure are formed and enclose the airtight and watertight padding located at described prefabricated rods border, it is also included for preventing from sealing
The limit assembly that assembly is taken up when prefabricated rods rise, described limit assembly include being installed on described fiber drawing furnace upper mounting seat,
Be connected in described mounting seat and adjustable position depression bar, described depression bar is pressed on described black box when putting down.
Optimize, described obturating cup, closure, airtight and watertight padding are quartz and make.
Optimize, described mounting seat includes passing through the Magnetic gauge stand of switch-mode regulation magnetic size, is arranged on described magnetic
Height-adjustable connecting rod on gauge stand, be rotationally connected with described connecting rod upper end and can adjust fixing with described connecting rod angle
Depression bar.
Further, described closure side wall is provided with two for the projection for depression bar pressing, and described obturating cup sets
There are two grooves matching with described projection.
Because technique scheme is used, this utility model compared with prior art has the advantage that this device is permissible
Effectively wire drawing fire door is sealed, and the limit assembly by being made up of depression bar, fixing bolt, expansion link and Magnetic gauge stand
Play and prevent prefabricated rods from airtight and watertight padding and closure taking up when lifting the accident generation causing fiber drawing furnace oxidation；Avoid and draw
The damage of graphite piece in silk stove, has prevented meaningless fiber loss and because the man-hour that fiber drawing furnace oxidation causes wastes, thus directly,
Indirectly improve economic effect to overflow.
Brief description
Accompanying drawing 1 is this utility model structural representation.
Specific embodiment
Shown embodiment is further described to this utility model below in conjunction with the accompanying drawings.
As shown in figure 1, air sealer of optical-fiber wiredrawing furnace includes black box and is used for preventing black box in prefabricated rods
The limit assembly being taken up when rising, described black box includes being placed on described fiber drawing furnace and middle part is offered and mated with prefabricated rods
The obturating cup 8 of insert port, be placed on described obturating cup 8 and middle part offer the insert port mated with prefabricated rods closure 6,
It is filled in the cavity that described obturating cup 8 and closure 6 are formed and encloses the airtight and watertight padding 7 located at described prefabricated rods border, described
Limit assembly include being installed on described fiber drawing furnace upper mounting seat, be connected in described mounting seat and adjustable position depression bar 2, institute
State when depression bar 2 puts down and be pressed on described black box.In the present embodiment, described obturating cup 8, closure 6, airtight and watertight padding 7 are equal
It is made up of quartz.Described mounting seat includes passing through the Magnetic gauge stand 5 of switch-mode regulation magnetic size, is arranged on described Magnetic gauge stand
Height-adjustable connecting rod 4 on 5, be rotationally connected with described connecting rod 4 upper end and can by bolt 3 adjust fixing with described company
The depression bar 2 of extension bar 4 angle.Described closure 6 side wall is provided with two for the projection for depression bar 2 pressing, on described obturating cup 8
It is provided with two grooves matching with described projection.
The quartz ring 1 selecting suitable dimension is enclosed within tail pipe, then this prefabricated rods is hung over wire-drawer-tower and enters on bar system,
Obturating cup 8 is put well on fiber drawing furnace upper cover plate, by entering bar system, optical wand is delivered in fiber drawing furnace by technological requirement, behind Jiao Hao center
Lift again, at prefabricated rods conehead, closure 6 is enclosed within prefabricated rods, then prefabricated rods are entered by technological requirement suitable in fiber drawing furnace
Work as position, then with strip airtight and watertight padding 7, obturating cup 8 inner space filled up, gently put down closure 6, closure 6 salient point with
Obturating cup 8 groove is relatively.Again Magnetic gauge stand 5 is fixed on the side of two salient points on fiber drawing furnace upper cover plate.Adjustable telescopic rod 4 is high
Degree, then depresses depression bar 2, so that depression bar 2 is just attached on closure 6 salient point, but must not make closure 6 stress, finally by solid
Determine bolt 3 to be fixed.
Wire drawing fire door can effectively be sealed by this device, and by by depression bar 2, fixing bolt 3, expansion link 4 and magnetic
The stopping means that property gauge stand 5 is formed play and prevent prefabricated rods from taking up and causing wire drawing airtight and watertight padding 7 and closure 6 when lifting
The accident of stove oxidation occurs；Avoid the damage of graphite piece in fiber drawing furnace, prevent meaningless fiber loss and because of fiber drawing furnace oxygen
Change the man-hour waste causing, thus directly, indirectly improve economic effect overflowing.
