Abstract
The invention discloses a novel thermocouple for measuring temperature of glass fiber access glass metal and an application method thereof. The thermocouple comprises a shell, a first thermocouple wire and an outer protective sleeve, wherein the shell is provided with an opening which is internally provided with a second thermocouple wire to form a double-wire thermocouple and is protected and positioned through the outer protective sleeve. According to the novel thermocouple, the temperature of the glass metal at two temperature measuring points with a fixed point distance is monitored at the same time, the diathermancy of the glass metal and the temperature drop gradient change caused by the environment can be reflected intuitively and the blindness for regulating the access temperature can be accurately eliminated so as to provide accurate reference for relatively accurate control of flow, temperature and number of drain plates.
Description
Technical field
The present invention relates to a kind of New-type thermocouple and method of application thereof that is used for glass path glass metal thermometric.
Background technology
In the spun glass forming process; Often need adjust optimum path temperature to adapt to the wire-drawing operation requirement; But the traditional hot galvanic couple is installed and used the temperature of glass liquid that mode only records 5cm place under the liquid level; This temperature is higher than the spun glass forming temperature far away, and the accuracy for the control of glass forming temperature is not enough under specific circumstances.There is the big temperature difference from top to bottom in glass metal in the path; The traditional approach measured temperature is higher than 60～90 ℃ of forming temperatures; Promptly enable in this case to realize to the measurement point accuracy control over temperature; Also occur changing in various degree, and then have influence on the height of bushing flow, bushing temperature, number numerical control system even wire-drawing operation efficient because of many-sided factor affecting such as frit property, path masonry, shaping area environment cause bushing top glass liquid temp.
Summary of the invention
The inaccuracy for the control of glass forming temperature causes the inefficient problem of wire-drawing operation in the prior art in order to overcome, and the present invention provides the New-type thermocouple and the method for application thereof that are used for glass path glass metal thermometric of the accurate monitoring temperature of a kind of ability.
The technical scheme that the present invention adopts is:
A kind of New-type thermocouple that is used for glass path glass metal thermometric; Comprise housing, first thermocouple wire and protective casing; Described first thermocouple wire is arranged on the bottom of described housing; It is characterized in that: perforate on said housing is provided with second thermocouple wire and forms the twin-core thermopair in the said hole; The spacing of described first thermocouple wire and second thermocouple wire constitutes by the glass metal potential difference of thermometric.
Further, the bottom that position of opening and said housing go deep into liquid level one end on the said housing is at a distance of 165～175mm.
A kind of method of application that is used for the New-type thermocouple of glass path glass metal thermometric as described above; It is characterized in that: the protective casing of said thermopair is inserted in the path from path top cover brick preformed hole; Said sleeve pipe upper flanges limit closely contacts with top cover brick upper surface and said sleeve position is fixed; Then said thermopair being inserted said cannula tip contact sleeve pipe bottommost is that the point for measuring temperature position is accurately located, and the thermo-electric metal pipe and the end cap that leak in said cover tube outside partly use tripod to fix.
Beneficial effect of the present invention is embodied in:
1, monitors two point for measuring temperature temperature of glass liquid of point of fixity distance in real time simultaneously;
2, the top point for measuring temperature is nearer apart from bushing filter screen distance, and the measured temperature and the forming temperature temperature difference are littler, and only 10～20 ℃, be beneficial to timely adjustment path temperature index, stablize wire-drawing operation;
3, monitor in real time through 2 temperature, can reflect the temperature drop graded that glass metal diathermancy and environment cause intuitively and accurately, eliminate the blindness of path temperature adjustment;
4, more accurately control for bushing flow, temperature and number number accurate reference is provided.
Choose reasonable point of the present invention apart from and the installation site, not only can realize that above thermometric need but also avoid bushing to change thermopair and sleeve pipe are caused damage; When utilizing existing thermopair to transform, when transforming the polishing porcelain bushing, need operation steadily, avoid damaging porcelain tube and cause fracture.

Embodiment
With reference to Fig. 2 and Fig. 4; A kind of New-type thermocouple that is used for glass path glass metal thermometric; Comprise housing, first thermocouple wire and protective casing; Described first thermocouple wire is arranged on the bottom of described housing, and characteristics are perforates on said housing, second thermocouple wire is set in the said hole forms the twin-core thermopair; The spacing of described first thermocouple wire and second thermocouple wire constitutes by the glass metal potential difference of thermometric.
Further, the bottom that position of opening and said housing go deep into liquid level one end on the said housing is at a distance of (L) 165～175mm.
A kind of method of application that is used for the New-type thermocouple of glass path glass metal thermometric as described above: the protective casing of said thermopair is inserted in the path from path top cover brick preformed hole; Said sleeve pipe upper flanges limit closely contacts with top cover brick upper surface and said sleeve position is fixed; Then said thermopair being inserted said cannula tip contact sleeve pipe bottommost is that the point for measuring temperature position is accurately located, and the thermo-electric metal pipe and the end cap that leak in said cover tube outside partly use tripod to fix.
When the present invention used, porcelain tube had the thermopair in four holes to transform in utilizing, after calculating according to access structure, get suitable point apart from L (170mm) back the polishing perforate install second thermocouple wire additional, process the twin-core thermopair.The platinum protective casing that thermopair is installed also prolongs transformation according to above distance; The platinum protective casing is installed earlier during installation; Then thermopair being encased in cannula tip, can to realize locating exactly thermopair top point for measuring temperature be chute brick bottom surface, and another point for measuring temperature is the original point for measuring temperature of 50mm under the liquid level.Thermopair install and fixing after connect the instant data that can record above 2 temperature of glass liquid behind thermocouple wire and the warm change equipment simultaneously.
The described content of this instructions embodiment only is enumerating the way of realization of inventive concept; Should not being regarded as of protection scope of the present invention only limits to the concrete form that embodiment states, protection scope of the present invention also reach in those skilled in the art conceive according to the present invention the equivalent technologies means that can expect.
