Description

Technical Field

[0001] This utility model relates to the field of basalt fiber melting technology, specifically to a fully electric vertical kiln basalt fiber melting channel. Background Technology

[0002] All-electric melting furnaces are kilns that use electricity as a heat source to melt basalt fibers. They typically employ indirect resistance radiation heating by installing silicon carbide or molybdenum disilicide resistance heating elements on the kiln sidewalls, controlling the temperature by adjusting power consumption. However, existing all-electric vertical melting furnaces suffer from poor basalt melt flowability, leading to excessive retention or accumulation of the basalt solution in certain process zones, affecting the clarification and homogenization of the basalt melt and production efficiency. Furthermore, the uniform control of heat energy across all process zones results in low heat utilization and high energy consumption, making it difficult to meet the temperature requirements of the basalt melt in different zones and ensuring optimal conditions for the basalt melt in various areas. Additionally, existing all-electric vertical melting furnaces are prone to crystallization at the kiln bottom and shallow liquid levels, impacting the clarification and homogenization of the basalt melt and overall furnace quality. Utility Model Content

[0003] To reduce energy consumption, improve production efficiency, enhance the processing effect of basalt melt, and ensure product quality, this utility model proposes a fully electro-melting vertical kiln basalt fiber melting channel, including an electro-melting control system and a furnace body. The furnace body includes a melting zone, a clarification and homogenization zone, and a working zone from one end to the other. The bottom surfaces of the melting zone and the clarification and homogenization zone are at the same height, and the bottom surface of the working zone is located above the bottom surface of the clarification and homogenization zone. The volume of the working zone is smaller than the volume of the clarification and homogenization zone, and the volume of the clarification and homogenization zone is smaller than the volume of the melting zone. A spinneret for drawing fibers is provided on the bottom surface of the working zone. Electrodes are provided in the melting zone, the clarification and homogenization zone, and the working zone, and each electrode in each zone is connected to an electro-melting control system.

[0004] Preferably, the melting zone and the clarification and homogenization zone are separated by a first partition, and the clarification and homogenization zone is separated from the working zone by a second partition. The first partition and the second partition are respectively provided with flow holes.

[0005] Preferably, the outer periphery of the furnace body is provided with a wall insulation layer.

[0006] Preferably, the wall insulation layer is constructed of fire-resistant bricks.

[0007] Preferably, the furnace body has a feeding port that communicates with the melting zone, and the feeding port is located at the top of the melting zone.

[0008] Preferably, the electrodes in the melting zone, the clarification and homogenization zone, and the working zone are located at the upper part of the sides of the melting zone, the clarification and homogenization zone, and the working zone, respectively.

[0009] The beneficial effects of this utility model are as follows:

[0010] In this invention, the volumes of the melting zone, the clarification and homogenization zone, and the working zone decrease sequentially. The melting zone has a large volume, which can continuously and stably provide the melted solution. The volumes of the clarification and homogenization zone and the working zone decrease sequentially, which limits the amount of melt in the clarification and homogenization zone and the working zone. This allows the melt to flow continuously from one area to the next in a timely manner, avoiding the accumulation of melt in the clarification and homogenization zone, ensuring the clarification and homogenization effect of the basalt melt and the high efficiency and stability of the production process.

[0011] In this invention, each electrode in each region is controlled by an individual electrofusion control system, allowing for independent temperature control within each region. This satisfies the temperature requirements of basalt melt in different process zones, ensuring the basalt melt remains in optimal condition across all zones. Conversely, when temperatures are uniformly controlled across all zones, the temperature in one zone may exceed the required temperature to adapt to other zones. This not only affects the processing efficiency of the basalt melt in that zone but also results in excess heat and energy waste. Furthermore, excessively high temperatures lower the molten melt level within the furnace. When the level is low, excess heat is easily absorbed by the furnace body, causing overheating, accelerating thermal erosion and aging, and shortening the furnace's lifespan. The individual temperature control design of this invention avoids these problems.

[0012] This invention features good melt fluidity, suitable temperature in each zone, and electrodes positioned on the upper part of the furnace side. This design prevents the melt from crystallizing due to accumulation or excessive heating, reducing the possibility of crystallization at the bottom of the furnace. Consequently, it avoids the subsequent melt processing and furnace structure being affected by crystallization, ensuring product quality and furnace lifespan. Attached Figure Description

[0018] Combined with appendix Figure 1 - Appendix Figure 2 A fully electric vertical kiln basalt fiber melting channel includes an electric melting control system and a furnace body 6. The furnace body 6 includes, from one end to the other, a melting zone 1, a clarification and homogenization zone 2, and a working zone 3. The bottom surfaces of the melting zone 1 and the clarification and homogenization zone 2 are at the same height. The bottom surface of the working zone 3 is located above the bottom surface of the clarification and homogenization zone 2. The volume of the working zone 3 is smaller than the volume of the clarification and homogenization zone 2, and the volume of the clarification and homogenization zone 2 is smaller than the volume of the melting zone 1. Specifically, the width dimension of the furnace body 6 at the melting zone 1, the clarification and homogenization zone 2, and the working zone 3 decreases sequentially. The top surfaces of the melting zone 1, the clarification and homogenization zone 2, and the working zone 3 are at the same height. The bottom surface of the working zone 3 is provided with a stencil 4 for drawing fibers.

[0019] Electrodes 5 are respectively installed in the melting zone 1, the clarification and homogenization zone 2, and the working zone 3. Each electrode 5 in each zone is connected to an electrofusion control system to realize individual temperature control of each zone, ensure the accuracy of temperature control, and enable the temperature in each zone to be controlled separately through the electrofusion control system. This ensures that the basalt melt in different zones is in the optimal state, improves the impurity removal rate, and further improves product quality.

[0020] Basalt raw material is first fed into melting zone 1, where electrodes 5 heat and melt it. The molten basalt then flows into clarification and homogenization zone 2, where electrodes 5 regulate its temperature, resulting in clarification and homogenization. The clarified and homogenized basalt then flows into working zone 3, where electrodes 5 regulate its temperature. Finally, the basalt flows out through a perforator 4, achieving wire drawing.

[0021] Specifically, the electrofusion control system can employ a power regulator and a transformer. The power regulator is electrically connected to the electrode 5 through the transformer. The power regulator outputs a current that has undergone power regulation. After the current is transformed by the transformer, it provides a suitable working voltage and current to the electrode 5, thereby achieving the regulation of the heating temperature.

[0022] Specifically, the melting zone 1 and the clarification and homogenization zone 2 are separated by a first partition 8, and the clarification and homogenization zone 2 is separated from the working zone 3 by a second partition 9. Flow holes 10 are respectively provided above the first partition 8 and the second partition 9. The molten liquid flows into the next zone through the flow holes 10.

[0023] Specifically, the furnace body 6 has a wall insulation layer on its outer periphery, and more specifically, the wall insulation layer is constructed of refractory bricks. The wall insulation layer can reduce heat loss, lower energy consumption, and improve energy utilization efficiency.

[0024] Specifically, the furnace body 6 has a feeding port 7 that communicates with the melting zone 1, and the feeding port 7 is located at the top of the melting zone 1. Basalt raw material is added into the furnace body 6 through the feeding port 7. More specifically, the feeding port 7 is connected to a continuous feeding device supply system to achieve a continuous and stable supply of raw materials, further ensuring the continuity of production. The continuous feeding device supply system can be a conventional feeding system, and will not be described in detail here.

[0025] Specifically, the electrodes 5 in the melting zone 1, the clarification and homogenization zone 2, and the working zone 3 are located at the upper part of the sides of the melting zone 1, the clarification and homogenization zone 2, and the working zone 3, respectively.
