Description

Technical Field

[0001] The utility model relates to the technical field of silicon production and processing, and more specifically, to an industrial silicon purification device. Background Art

[0002] Industrial silicon is a product smelted from silica and carbonaceous reducing agents in a submerged arc furnace. After a series of processes, industrial silicon is purified to produce polysilicon and monocrystalline silicon for use in the photovoltaic industry. In order to reduce the impurity content in industrial silicon and improve its quality, it is necessary to refine and purify industrial silicon.

[0003] In the existing mechanism during processing, since the gas in the gas mixing chamber is naturally transported through the air pipe, the transportation pressure is relatively low. During the processing of liquid silicon, impurities may block the air vent, resulting in poor purification efficiency. Moreover, the oxygen and air in the gas mixing chamber are naturally mixed, and the mixing speed is slow, resulting in the mixed gas discharged through the air vent not being pure enough, leading to poor refining quality of industrial silicon.

[0004] After retrieval, a Chinese patent with the authorization announcement number CN215939996U discloses a refining and purification device for industrial silicon production and processing. In this structure, the microwave heater and the motor are started simultaneously, the driving rod rotates, and the stirring plate rotates to stir the heated liquid industrial silicon. When the liquid industrial silicon is processed, while being stirred by the stirring plate, the rotating rod also drives the fan blades to rotate, accelerating the mixing efficiency of oxygen and air in the gas mixing chamber. Then, the mixed gas is sprayed out through several electronic control nozzles to fully react with the stirred liquid industrial silicon. The bubbles generated by the spraying of the mixed gas will make the liquid silicon flow, making the removal of impurities more thorough, improving the purification efficiency of industrial silicon during processing and production. The waste gas with heat discharged through the exhaust pipe is discharged into the heat preservation pipe, and the heat in the waste gas is used to heat the mixed gas, reducing heat loss and lowering energy consumption.

[0005] However, when this structure is actually used, the mixing efficiency of oxygen and air in the gas mixing chamber is accelerated, and then the mixed gas is sprayed out through several electronic control nozzles to fully react with the stirred liquid industrial silicon. However, the range of the mixed gas sprayed out through several electronic control nozzles is small, resulting in poor reaction effect and uneven mixing, affecting the subsequent purification quality.
