Description

Technical Field

[0001] The utility model relates to the technical field of industrial silicon refining, in particular to an industrial silicon melting and refining device. Background Art

[0002] Industrial silicon, also known as semi-metallic silicon, is a product name that appeared in the mid-1960s. Metallic silicon is a product smelted from silica and carbonaceous reducing agents in a submerged arc furnace. The content of the main component silicon element is about 98% (in recent years, silicon containing 99.99% Si is also listed in metallic silicon), and the remaining impurities are iron, aluminum, calcium, etc. Due to its different uses, it is divided into various specifications. According to the content of iron, aluminum and calcium in semi-metallic silicon, semi-metallic silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101, etc. The additional products of semi-metallic silicon include microsilica fume, edge silicon, black silicon, metallic silicon slag, etc. Among them, microsilica fume is also called silica fume, which is widely used in refractory and concrete industries.

[0003] For example, a Chinese patent discloses: a high-refined copper refining device, patent number: CN219731083U, through the coordinated arrangement of a partition, an electrolytic chamber, a cooling pipe, a liquid inlet pipe, a first liquid discharge pipe, and a valve, the output end of the cylinder is controlled to be ejected, and the fixed plate and the stainless steel partition are lowered. The stainless steel partition separates the molten material in the electrolytic chamber into independent parts, and after it solidifies, it is cooled. The cooling process is rapid cooling, which improves the refining speed of refined copper, that is, water is introduced into the cooling pipe through the liquid inlet pipe to continuously cool the partition, and the water is discharged from the first liquid discharge pipe. The flowing water quickly takes away the heat of the partition and the solidified material. At the same time, water is passed through the first insulating pipe, and the water is sprayed onto the copper block from the water outlet, so that the copper block is quickly cooled in two cooling methods, thereby further optimizing the cooling process of the copper block, so that the copper block can be quickly cooled, so as to quickly reach the standard for electrolysis, thereby greatly improving the refining speed and efficiency of refined copper.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: as mentioned above, the device quickly cools the melt by adding water, but when there are a large number of impurities inside the melt that need to be processed, if it cannot be stirred, the melt can only be heated continuously, causing the impurities inside the melt to precipitate by themselves, thereby reducing the efficiency of melt refining.
