It is possible to effectively improve melting efficiency of basalt.
Description
Technical field
The present invention relates to the electrofusion of basalt continuous fiber to prepare, particularly relate to a kind of vertical-insert electrode basalt continuous fiber kiln.
Background technology
Basalt is high due to fusion temperature, and color is black, corrode the factors such as big, can not improve its fusing effect always.Start, from the 1980's, the shallow-layer melting method that the former Soviet Union utilizes top flame melting, but in drawing process inefficiency.And in alkaline-resisting basalt fibre manufacture method as described in CN00110460, product and equipment, utilize plate electrode fused basalt fiber.But owing to basalt iron-holder is high, very easily with molybdenum electrode generation displacement reaction, cause that molybdenum electrode causes kiln to be shorter than 6 months service life because corroding.Thus resulting in production cost high, product quality defect is many.And in a kind of kiln producing basalt fibre described in CN104692647A, although kiln is changed into circle from rectangle, though certain production efficiency can be improved, but the present situation that molybdenum electrode plate corrosional kiln service life is low and product quality is low can not be changed, this is also off at the beginning of 2015, the yield of the basalt continuous fiber that China is annual is only about 5000 tons, and this kiln with basalt continuous fiber has immediate cause.
Summary of the invention
The technical problem to be solved is to provide a kind of vertical-insert electrode basalt continuous fiber kiln, is effectively improved basaltic melting efficiency.
The technical solution adopted for the present invention to solve the technical problems is: providing a kind of vertical-insert electrode basalt continuous fiber kiln, including melting tank, described melting tank is provided with charging aperture；The bottom of described melting tank is inserted with bar-shaped molybdenum electrode, is cased with chiller outside described bar-shaped molybdenum electrode, and described bar-shaped molybdenum electrode is connected with Scott Transformer by wire.
Described bar-shaped molybdenum electrode has 4～8 pairs.
Described bar-shaped molybdenum electrode tilts 0～10 ° to the center position of described melting tank.
The pool wall of described melting tank adopts fine and close chrome brick to make, and bottom adopts Corhart Zac-block to make.
Described chiller includes cooling jacket, and described cooling jacket is socketed in outside described bar-shaped molybdenum electrode, and is positioned at outside described melting tank, and described cooling jacket is respectively arranged with water inlet pipe and outlet pipe.
Beneficial effect
Owing to have employed above-mentioned technical scheme, the present invention compared with prior art, has the following advantages that and good effect:
The present invention utilizes the bar-shaped end to insert molybdenum electrode, after bottom molybdenum electrode is generated heat, due to effect of expanding with heat and contract with cold, realize the convection current of Basalt melt at positions such as kiln centers, effectively solve to cause because ferrum is painted the defect of the low heat conduction of basalt, realize conduction of heat by convection current and improve melting efficiency.
The present invention utilizes the end to insert stick electrode, can pass through bottom Push Technology, effectively solves the molybdenum electrode consumption because ferrum reduction causes, improves the service life of kiln.
The inner lining material of kiln uses erosion-resistant fine and close chrome brick and Corhart Zac-block, effectively coordinates the service life of molybdenum electrode so that the service life of basalt continuous fiber kiln less than 6 months, brings up to more than 24 months from current.
The present invention utilizes Scott transformator to control the slotting molybdenum electrode in the end, make the electric field in basalt fibre kiln stable, the electric field at each position of electrode is consistent, each position is corroded consistent, it is thus possible to effectively reduce basalt fusing energy consumption, reduce the end breakage rate of basalt fibre, improve molten quality, improve the quality of basalt continuous fiber.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is expanded on further.Should be understood that these embodiments are merely to illustrate the present invention rather than restriction the scope of the present invention.In addition, it is to be understood that after having read the content that the present invention lectures, the present invention can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally.
Embodiments of the present invention relate to a kind of vertical-insert electrode basalt continuous fiber kiln, as it is shown in figure 1, include melting tank 2, described melting tank 2 is provided with charging aperture 1；The bottom of described melting tank 2 is inserted with bar-shaped molybdenum electrode 6, is cased with chiller 5 outside described bar-shaped molybdenum electrode 6, and described bar-shaped molybdenum electrode 6 is connected with Scott Transformer by wire 9.Wherein, described bar-shaped molybdenum electrode 6 can have 4～8 pairs.Described bar-shaped molybdenum electrode 6 tilts 0～10 ° to the center position of described melting tank 2.The pool wall of described melting tank 2 adopts fine and close chrome brick 3 to make, and bottom adopts Corhart Zac-block 4 to make.Described chiller includes cooling jacket 5, and described cooling jacket 5 is socketed in outside described bar-shaped molybdenum electrode 6, and is positioned at outside described melting tank 3, and described cooling jacket 5 is respectively arranged with water inlet pipe 7 and outlet pipe 8.
As can be seen here, when molybdenum electrode consumes because of displacement reaction, it is possible to supplemented by electrode Push Technology, simultaneously in order to coordinate the long-life of molybdenum electrode, the liner tile of whole kiln adopts fine and close chrome brick and Corhart Zac-block, therefore can reach more than 24 months the service life of this kiln.
