The conditions of high tank furnace investment cost, low yield, unstable fiber performance and the like of more production enterprises at present are caused, and the existing production technology and process have a large lifting space.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", etc. may explicitly or implicitly include one or more such feature. In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more. The terms "mounted," "connected," "coupled," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art in a specific case.
As shown in fig. 1, 2 and 3, a specific implementation mode of the special multi-bushing tank furnace for producing the pure basalt fiber disclosed by the invention is as follows: each unit kiln is provided with a plurality of charging ports 1 which are mainly arranged at the relative center position of a melting part cover plate 2, basalt ores reach the lower part of the charging ports 1 through an automatic charging machine, a plurality of burners 3 are arranged below the melting part cover plate 2, the burners 3 heat the whole melting flame space 4 by adopting a pure oxygen and natural gas premixing system as a medium, the basalt ores entering the kiln are primarily melted by the radiant heat of the melting flame space 4, the liquid level 5 is used as a limit, the lower half part of the furnace is heated by adopting a bottom inserting electrode 6, 10 rod-shaped molybdenum electrodes are arranged in the melting area part, and the glass liquid is effectively heated by adopting a three-phase Scott transformer power supply mode. The glass liquid heated by the melting part and the bottom inserting electrode 6 through the radiation heat of the flame melting space 4 flows through the clarifying channel 7, 10 side inserting electrodes 8 are preset in the clarifying channel 7, each group of electrodes of the side inserting electrodes 8 uses a single-phase step-down transformer to supply power, the temperature of the glass liquid from the melting part and the primary molten glass liquid is orderly regulated to achieve the glass liquid clarifying effect, the clarified glass liquid flows to the climbing bricks 9 and finally enters the operation channel 10, the climbing bricks 9 mainly block the bottom impurities possibly remained in the primary melting and clarifying process, after the glass liquid enters the operation channel 10, the channel flame space 13 is effectively heated by the channel burner 12 arranged below the channel cover plate 11, and the stable temperature is kept so that the glass liquid smoothly enters the drain plate 14 and the stable wiredrawing operation state is kept.
The level 5 is determined based on the level of glass in the working channel (e.g., 400 mm) and then pushed back, plus the ramp height, e.g., 100 mm. Thus, it was confirmed that the entire liquid level was 300 mm. The depth of the electrode inserted into the molten glass was 5 mm (295 mm) lower than the total level of the liquid so as to sufficiently melt the ore.
The arrangement of the bottom plug electrodes 6 has very strict requirements, one according to the current density of the molten glass (molten material) in the kiln, and the second according to the number and distance of the electrodes arranged by using the type of the transformer. And thirdly, the arrangement is based on the entire melting capacity of the melting part. (three electrodes are 1 group, using Scott transformers, adjacent common electrodes 40 are positioned as shown in FIG. 4). Is uniformly arranged in the melting part, so that the melting part is sufficiently melted. The distance between the side inserted electrodes is 280mm, which is the best state, less than 280mm, the energy consumption is high (the number of electrodes is more arranged at the same distance), and when the distance is more than 280mm, adverse effect is brought, because the glass liquid is seriously cooled, and the glass liquid needs to be reheated to keep proper temperature. The output power of each side-inserted electrode is configured to be sequentially reduced, for example: the first group of side-inserted electrodes are symmetrically arranged at 2.5kw, the second group of side-inserted electrodes are 2.2kw, the third group of side-inserted electrodes are 2.0kw, the fourth group of side-inserted electrodes are 1.9kw, and the fifth group of side-inserted electrodes are 1.8kw.
Whether the glass liquid (melt) is clear or not can be determined as follows: if the wire drawing operation is stable, the clarifying effect of the glass liquid is achieved. The laboratory uses log2.5 pairs to determine the relationship between glass temperature and viscosity to demonstrate whether a fining effect is achieved. Then in the present case, we use the parameters of the multiple groups of side-inserted electrodes and the temperature change of the molten glass to describe and achieve the clarification effect: the side-inserted electrode is stable after reaching the set parameters, and no larger voltage fluctuation occurs.
In this embodiment, the unit kiln is responsible for meeting the melting requirements and the melting efficiency can be adjusted with the melt quality maintained depending on the aggregate output of the bushing 14. The shared operation passage uses high-quality refractory materials, so that the service life of more than 5 years is ensured, the unit kilns are made of common refractory materials, and a certain unit kiln can be shut down at any time according to the production energy arrangement, so that the flexible requirement of reducing the production energy is achieved. When the unit kiln fails, any one of the unit kilns can be shut down, so that the unit kiln is overhauled, and the discharging amount of the operation passage is properly reduced without stopping production.
The experimental results can be obtained: the electric power of the unit kiln is about 75Kw/H, and the natural gas is about 8.5M 3 /H, working channel using natural gas about 27M 3 The electric power of the bushing plate 14 is about 10.5Kw/H and the discharge amount is about 32KG/H. The full cylinder rate is about 70%, the wiredrawing yield is about 85%, and the wiredrawing yield is improved by about 15% compared with the common process scheme. In the embodiment of the invention, 12 fast 800-hole bushing plates are installed together, the daily output is about 9.2 tons, the total power is about 576Kw/H, and the total amount of natural gas is about 78M 3 And (3) converting the standard coal into 0.85 ton of coal/ton of yarn, and reducing the energy source by about 35% compared with the common process scheme.
In summary, the invention realizes the requirement of stable operation of the multi-bushing tank furnace by constructing a plurality of electric mixing melting furnaces and a common operation material channel. According to the design of fiber production tank furnaces at home and abroad and combining the characteristics of basalt glass melt, the invention adopts an innovative process layout, is based on single basalt furnaces, solves the requirement of full melting by arranging a plurality of single furnaces on two sides of a common operation material channel, is provided with a reasonable melt climbing material channel so as to fully ensure that the melt entering the common operation material channel meets the requirement of wire drawing, and ensures that the temperature in the channel is uniform by adopting a pure oxygen combustion technology and the quality of the melt (molten material) is stable, thereby solving the bottleneck of producing the multi-bushing for basalt fiber. Indirectly provides basic conditions for producing high-performance basalt fibers with low energy consumption, and solves important technical bottlenecks for basalt fiber industrialization.
