Description

Technical Field

[0001] This utility model relates to the field of basalt fiber melting technology, specifically to an electrofusion system for melting basalt fibers in a fully electrofusion vertical kiln. Background Technology

[0002] An all-electric melting furnace is a type of equipment that uses electricity as a heat source for the production of basalt fibers. These furnaces typically have resistance heating elements installed on the side walls of the furnace chamber, efficiently converting electrical energy into heat energy through indirect resistance radiation heating, thereby achieving the melting and other processing of basalt raw materials.

[0003] However, current all-electric vertical melting kilns have certain shortcomings in actual operation: Existing all-electric vertical melting kilns use a uniform standard for heat control in each process zone, making it difficult for the temperature in some zones to remain within the required range. This results in insufficient and inefficient utilization of heat, leading to energy waste. Furthermore, basalt melt has different temperature requirements in different process stages such as melting, clarification, and homogenization. The current single heat control mode of all-electric vertical melting kilns cannot meet the precise temperature requirements of the melt in different process zones, making it difficult for the basalt melt to maintain its optimal state in each zone. This affects the clarification and homogenization effect of the basalt melt, leading to a decline in product quality. In addition, the electrodes in existing all-electric vertical melting kilns are often distributed on one side, resulting in uneven and unstable temperature regulation within each zone, which also affects the clarification and homogenization effect of the basalt melt. Utility Model Content

[0004] To reduce energy consumption, improve production efficiency, enhance the processing effect of basalt melt, and ensure product quality, this utility model proposes an electrofusion system for melting basalt fibers in a fully electrofusion vertical kiln. The system includes electrodes, an electrofusion control device, and a cooling device for cooling the electrodes. The electrodes include a first electrode, a second electrode, and a third electrode. There are at least two first electrodes, and two second and two third electrodes are respectively provided. The two first electrodes are symmetrically arranged on the furnace body on both sides of the melting zone of the fully electrofusion vertical kiln. The two second electrodes are symmetrically arranged on the furnace body on both sides of the clarification and homogenization zone of the fully electrofusion vertical kiln. The two third electrodes are symmetrically arranged on the furnace body on both sides of the operating zone of the fully electrofusion vertical kiln. Each of the first, second, and third electrodes is connected to an electrofusion control device.

[0012] The beneficial effects of this utility model are as follows:

This design precisely meets the temperature requirements of basalt melt in different process zones, ensuring that it is in optimal condition in each zone and thus guaranteeing product quality. Simultaneously, the individual temperature adjustment of each zone prevents the current zone temperature from exceeding its required temperature, avoiding excess heat and energy waste.

It should be understood that the given embodiments are only one of the implementation methods and do not represent all embodiments.

[0021] In this article, terms such as "inner," "outer," "upper," and "lower" are established based on the positional relationships shown in the attached drawings.

[0022] Combined with appendix Figure 1 - Appendix Figure 4 An electrofusion system for melting basalt fibers in a vertical kiln with all-electric melting includes electrodes, an electrofusion control device, and a cooling device for cooling the electrodes. The electrodes include a first electrode 1, a second electrode 2, and a third electrode 3. Specifically, the electrodes are molybdenum electrodes, meaning that the first electrode 1, the second electrode 2, and the third electrode 3 are all molybdenum electrodes. Molybdenum has a high melting point and high strength, and exhibits good stability and corrosion resistance at high temperatures. It also has good compatibility with basalt melt, which can reduce electrode contamination of the melt and thus improve the quality of basalt fibers.

[0023] There are at least two first electrodes 1, two second electrodes 2, and two third electrodes 3. The two first electrodes 1 are symmetrically arranged on the furnace body on both sides of the melting zone 8 of the all-electric melting vertical kiln. The two second electrodes 2 are symmetrically arranged on both sides of the furnace body on both sides of the clarification and homogenization zone 9 of the all-electric melting vertical kiln. The two third electrodes 3 are symmetrically arranged on both sides of the furnace body on both sides of the working zone 10 of the all-electric melting vertical kiln. The first electrode 1, the second electrode 2, and the third electrode 3 are each connected to an electro-melting control device. The temperature in each zone is precisely controlled by the electro-melting control device to ensure that the basalt melt in different zones is in the best state, improve the impurity removal rate, and improve product quality.

[0024] Specifically, the cooling device includes a cooling water pipe 4, an inlet pipe 5, and a drain pipe 6. The cooling water pipe 4 is provided with a cooling water jacket 11, and each electrode is fitted with a cooling water pipe 4 on its outer side.

[0025] One end of the water inlet pipe 5 and the water outlet pipe 6 are connected to the cooling water jacket 11, and the other end of the water inlet pipe 5 and the water outlet pipe 6 are connected to the cooling water storage tank 7.

[0026] The cooling device also includes a first water pump 12 and a second water pump 13. The inlet pipe 5 and the outlet pipe 6 are each provided with two sections. The input end of the first water pump 12 is connected to the cooling water storage tank 7 through one section of the inlet pipe 5, and the output end of the first water pump 12 is connected to the cooling water jacket 11 through the other section of the inlet pipe 5. The input end of the second water pump 13 is connected to the cooling water jacket 11 through one section of the outlet pipe 6, and the output end of the first water pump 12 is connected to the cooling water storage tank 7 through the other section of the outlet pipe 6.

[0027] Cooling water is pumped from the cooling water storage tank 7 by the first water pump 12 into the cooling water jacket 11 through the inlet pipe 5. The cooling water in the cooling water jacket 11 absorbs the heat generated by the electrode during operation. Then, it is pumped back from the cooling water jacket 11 to the cooling water storage tank 7 by the second water pump 13 through the drain pipe 6. This circulating cooling water removes the heat generated by the electrode during operation, keeping the electrode within a suitable temperature range, extending the electrode's service life, and ensuring the stable operation of the electrode assembly.

[0028] Specifically, the first electrode 1 is provided in multiple pairs along a first direction, with two first electrodes 1 in each pair symmetrically arranged on both sides of the furnace body of the melting zone 8 of the all-electric melting vertical kiln. The first direction is the length direction of the melting zone 8, that is, the direction from the side of the melting zone 8 away from the clarification and homogenization zone 9 to the side of the melting zone 8 closer to the clarification and homogenization zone 9. The number of pairs of first electrodes 1 is set according to the length of the melting zone 8 to ensure that the first electrodes 1 can heat the entire melting zone 8.

[0029] Specifically, the electrofusion control device includes a transformer 14, a power regulator 15, and thermocouples 16. The thermocouples 16 are positioned in the areas corresponding to their respective electrodes. Specifically, the thermocouple 16 connected to the first electrode 1 is positioned in the melting zone 8; the thermocouple 16 connected to the second electrode 2 is positioned in the clarification and homogenization zone 9; and the thermocouple 16 connected to the third electrode 3 is positioned in the working zone 10. The power regulator 15 is electrically connected to both the thermocouples 16 and the electrodes, and the transformer 14 connects the power regulator 15 to the electrodes. The thermocouples 16 measure the temperature of their respective zones. The power regulator 15 adjusts its output power and changes the output current based on the temperature. The adjusted current then passes through the transformer 14, which transforms the voltage, ultimately inputting the current and voltage to the electrodes to regulate the motor power and achieve precise control of the basalt raw material processing temperature.

[0030] Specifically, the electrodes in the melting zone 8, the clarification and homogenization zone 9, and the working zone 10 are located at the upper part of the sides of the melting zone 8, the clarification and homogenization zone 9, and the working zone 10, respectively.
