As stopper rod needs to be rotated in some cases, so when in being put into melting furnace every time, it may be difficult to ensure
All it is vertical state, this can cause the sealing effectiveness to exporting to reduce.By vertical alignment unit, every time stopper rod can put
Before entering melting furnace, stopper rod is calibrated to into vertical state, then keeps its vertical state to be moved in melting furnace, so as to reality
Now to exporting more preferable sealing effect.
Preferably, also include：Insulating barrier 20, is arranged between linking arm 3 and stopper rod 2.Raw material in melting furnace is at some
In the case of be carried out using electrode it is direct-fired, by arranging insulating barrier, can prevent in melting furnace electrode and linking arm it
Between produce electric current, it is to avoid operating personnel's electric shocks, it also avoid the infringement to other electrical equipments in system.
As shown in Figure 5, it is preferable that stopper rod 2 is taper near one end of outlet.The tip of taper has difference in the axial direction
Radius, so when stopper rod is moved up and down, stopper rod can more uniformly change with tip location to the degree of outlet closing,
Certainly, stopper rod can also be set to elliposoidal or spherical near one end of outlet by user as needed.In addition, stopper rod can be adopted
Take heat-resistant conductive material to make, for example molybdenum.
The control flow of fused ceramic fiber flow control system according to an embodiment of the invention is concrete such as Fig. 6 institutes
Show.
First by image measuring apparatus, temperature measuring equipment and/or Weight-measuring device, the note of collection melting outlet of still
Stream information, then by the beam feedback of the information for collecting to controller, controller parsing beam information judges flow and normal stream
Amount is compared larger still less, sends control letter to driving element and/or melting furnace heating unit according to the information that obtains of parsing
Number, rise or fall driving element control stopper rod, or control melting furnace heating unit power is raised and lowered, if flow direction and mark
Quasi- flow compares less, then control stopper rod rising, or control melting furnace heating unit power rising, melts so as to improve outlet outflow
Melt the flow of ceramic fibre, conversely, then control stopper rod decline, or control melting furnace heating unit power is reduced, so as to reduce out
Mouth flows out the flow of fused ceramic fiber
Technical scheme is described in detail above in association with accompanying drawing, it is contemplated that in the related, in ceramic fibre
Manufacturing enterprise, mainly manually sees melting beam by rule of thumb to adjust electrode current, changes liquation viscosity, so as to accelerating or subtracting
Little flow velocity, realizes the regulation of fused ceramic fiber flow, and this manual adjustment mode subjectivity is larger, and degree of regulation is not enough, raw
The ceramic fiber products quality of output is undesirable, and adjusts very time-consuming, high labor intensive.By the technical side of the application
Case, is input into control instruction to adjust stopper rod to melting the degree of closure of outlet of still by controller, so as to realize to flowing out melting
The mechanization of ceramic fibre flow, reduces manual labor amount, improves the precision and efficiency of Flow-rate adjustment.And can pass through
Measurement apparatus monitoring melting outlet of still flows out the beam information of fused ceramic fiber, carrys out automatic adjusting plug bar to melting outlet of still
Degree of closure, so as to realize automatically adjusting to flowing out fused ceramic fiber flow, and combines image measuring apparatus, temperature survey
Amount device and/or Weight-measuring device, can comprehensively monitor the beam information for flowing out fused ceramic fiber, so as to controller
There is provided more comprehensive monitoring information so that controller generates more accurate control signal, and by grand driver element and
Micro-move device unit is combined and is driven, and can accurately adjust the motion of stopper rod, so as to realize the accurate tune to exporting closed stratum
Section, and then realize the accurate adjustment to fused ceramic fiber flow.
In the present invention, term " multiple " refers to two or more, unless otherwise clearly restriction.
The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
