Description
Technical Field
[0001] The utility model relates to the technical field of automatic eye plugging devices, in particular to an automatic eye plugging device for industrial silicon. Background Technique
[0002] As an important basic industrial raw material, industrial silicon is widely used in fields such as electronics, chemical industry, and metallurgy. Its production usually adopts the submerged arc furnace smelting method, in which raw materials such as silica and carbonaceous reducing agents are subjected to a reduction reaction at high temperature to obtain liquid industrial silicon. During the production process, the submerged arc furnace needs to discharge slag regularly and perform eye plugging operations. Traditional eye plugging methods are mostly manual operations, which have many drawbacks. On the one hand, the labor intensity is high. Operators need to push the eye plugging material into the furnace eye with tools in a high-temperature and high-dust environment, consuming a large amount of physical strength and time. On the other hand, the working environment is harsh, with high temperature and a lot of dust on site, which endangers the health of operators and is prone to cause occupational diseases. At the same time, the safety risk is high. Operators are easily scalded or burned when approaching the high-temperature furnace eye, and manual operations are prone to errors, resulting in the leakage of liquid silicon and high-temperature gas and triggering safety accidents. In addition, it is difficult to ensure the eye plugging effect, and the accuracy and stability of manual eye plugging are poor. With the development of industrial automation technology, the demand of enterprises for automated solutions is becoming increasingly urgent. In the field of industrial silicon production, the demand for automatic eye plugging devices is also increasing. The automatic eye plugging device can replace manual operations in a harsh environment, and has the advantages of high precision, good stability, safety and reliability, etc. It can greatly improve production efficiency, reduce labor intensity, improve the working environment, and improve safety performance, bringing significant economic and social benefits to enterprises.
[0003] However, for traditional equipment, traditional equipment usually adopts manual eye plugging. Manual eye plugging requires operators to work in a high-temperature and high-dust environment, and the labor intensity is very high. Operators need to use tools to push the eye plugging material into the furnace eye, which requires a large amount of physical strength and time. At the same time, the accuracy and stability of manual eye plugging are poor, and it is difficult to ensure the eye plugging effect. If the eye plugging is not tight, it will cause the leakage of liquid silicon and high-temperature gas in the furnace, affecting the normal progress of production, and improvement is needed.
