Description
Technical field
The utility model relates to basalt fibre manufacture fields, and in particular to a kind of basalt fibre melting tank furnace.
Background technique
Basalt fibre is basalt ore under 1450~1500 DEG C of high-temperature fusions, is formed by cooling after bushing wire drawing
A kind of inorganic high-performance fiber.Basalt fibre has that high-low temperature resistant, the coefficient of heat conduction is low, hygroscopicity is strong, anticorrosive, anti-spoke
It penetrates, the excellent properties such as tensile strength height, elasticity modulus height, there is extensive prospect of the application.
But since the viscosity temperature of basaltic suitable wire drawing is very high and temperature range is narrow, while basalt has very
High crystallization temperature and thermal conductivity is poor, so that the temperature difference is larger not easy to control between the basalt in tank furnace different zones.
This, which to have the molten basalt for not meeting wire-drawing temperature requirement to enter, carries out wire drawing in bushing, lead to the life of basalt fibre
Production process more, low phenomenon of fibrous finished product rate in the presence of the winged silk that breaks end, increases cost and energy consumption.
Utility model content
In view of this, the application provides a kind of basalt fibre melting tank furnace, set by being combined in the melting zone of tank furnace
Burning heater and columnar electrode are set, molten basalt is heated from different positions, so that molten basalt energy
It is enough sufficiently heated, it ensure that the consistency of basaltic temperature in tank furnace.
In order to solve the above technical problems, technical solution provided by the utility model is a kind of basalt fibre melting tank furnace,
Including kiln, the kiln includes interconnected melting zone and settling section, and the melting zone is equipped with far from the side of settling section
Feed inlet；At the top of the melting zone and/or side wall is equipped with burning heater, and melting zone bottom is equipped with the column electricity to raise upward
Pole；The settling section is equipped with discharge port far from the side of melting zone, and settling section bottom is equipped with bubbling device.
Preferably, the burning heater is arranged on the side wall of kiln, misplaces between the burning heater being arranged oppositely
Setting.
Preferably, it is less than close to the adjacent burning heater spacing distance of feed hole area far from feed hole area
The spacing distance of the adjacent burning heater.
Preferably, the kiln is rectangular parallelepiped structure, and the length-width ratio of the kiln is 2.2-4.5:1.
Preferably, the depth of the melting zone is 200-600mm.
Preferably, the depth of the settling section is 50-200mm more shallow than melting zone, passes through between the settling section and melting zone
Inclined-plane connects transition.
Preferably, the columnar electrode phase intervals are arranged, and the phase between adjacent column electrode is different.
Preferably, discharge port be dog-hole structure, the discharge port be arranged in settling section far from the side wall of melting zone in the middle part of.
The application compared with prior art, it has the advantage that:
Melting zone and settling section mentioned here refer in kiln for by region that basalt melts and being used to melt
The clear region of basalt, without specific demarcations between two pieces of regions；Kiln, which is divided into two pieces of regions according to function, is
In order to provide the reference azimuth of relative straightforward when describing the position of component.Combustion at the top of melting zone and/or on side wall is set
Burning heater and heat to basalt from surface layer melts basalt.When basalt is molten into liquid, in basalt two
The components such as silica, aluminum oxide, calcium oxide ionize, and isolate cation and anion, so that it is provided with electric conductivity,
It is arranged between the columnar electrode of tank furnace bottom and is switched on.Since molten basalt has resistance, so when electric current passes through the Black Warrior
Rock can generate resistance heat when transmitting between the electrodes, to further heat to basalt, make positioned at the profound of tank furnace bottom
Wu Yan can also be heated, to be stably maintained within the scope of temperature needed for wire drawing.
Set up the burning heater on the side wall of two sides separately, basalt is heated by combustion flame.If opposite direction is set
The burning heater alignment setting set, then the flame of two sides overlaps to and causes over-heating together, and adjacent burning heater
Between region then because not heated and temperature is insufficient.
Increase the burning heater smaller interval being arranged at feed inlet, the i.e. density of setting of the burning heater in the region
It is higher, so that the heating efficiency in the region is higher, basalt can be made rapidly to be heated melting, convenient for carrying out electrode conduction
Further heat temperature raising.
Basalt raw material enters from the feed inlet that kiln one end is arranged in, and with the mobile melting in kiln and gradually adds
Heat is to temperature needed for fiber draw.Kiln length is too short to be easy to cause basalt heating to be not enough；And due to basalt
It is sufficiently heated to preset temperature, therefore kiln length is too long too many necessary for basaltic heating nothing, increases the Black Warrior instead
The flowing time of delivery of rock, causes to waste.
Although the technical program uses the method for the columnar electrode heating of top burning heater cooperation bottom to realize
Heating so that the basalt of upper layer and bottom can sufficiently be heated, but if kiln is too deep, then due to basalt thermal conductivity compared with
Difference, heat, which can not transmit, is sufficiently transmitted to each region, causes the melt temperature gap of different layers in kiln larger, influences to melt
Quality；If melting zone is excessively shallow, how much is the amount of molten basalt, limits the preparation efficiency of basalt fibre.Column electricity simultaneously
It can be most probably burned because of excessively close away from burning heater, influence equipment normal operation.
A shallower settling section is arranged after melting zone to be conducive to melt because the basalt depth of settling section is shallower
Bubble discharge in basalt, the mobility for being also more favorable for improving molten basalt reach to guarantee the consistency of temperature
Better homo-effect.
Phase is different between adjacent columnar electrode, maximum potential difference is formed between adjacent column electrode, to guarantee
Current path of the electric current in molten basalt, convenient for heated by electrodes region and power regulate and control.
The molten basalt of close kiln side wall leads to temperature due to the heat transfer of side wall.Settling section is arranged in discharge port
In the middle part of side wall, the side wall apart from two sides all farther out so that the basalt melt into the discharge port of dog-hole structure is kiln
Temperature is higher in furnace, the preferable basalt of molten condition, ensure that the molding quality of fiber draw.
