Description

Technical Field

[0001] The utility model relates to the field related to metal silicon processing equipment, in particular to a metal silicon intelligent temperature control smelting device. Background Art

[0002] Metallic silicon is also called crystalline silicon or industrial silicon. Industrial silicon is a kind of semi-metal, formerly known as "silicon", with a melting point of 1420°C and a density of 2.34g / cm 3 , hard and brittle, insoluble in acid at room temperature, easily soluble in alkali, the properties of industrial silicon are similar to those of germanium, lead and tin, and it has semiconductor properties. Industrial silicon is extremely abundant in the earth's crust, second only to oxygen, accounting for more than a quarter of the total weight of the earth's crust, and exists in the form of silicon dioxide or silicates. The purest silicon mineral is quartz or silica. Silicon has two allotropes: one is a dark brown amorphous powder with active properties that can burn in the air; the other is a stable crystal (crystalline silicon). During the smelting process, the temperature inside the smelting furnace has a certain influence on the quality of industrial silicon. Therefore, it is particularly important to control the temperature inside the smelting furnace during the smelting process.

[0003] In the prior art, the optimization of industrial silicon smelting devices is mostly reflected in the feeding device. For example, the Chinese patent document with the announcement number CN220201454U discloses an industrial silicon smelting device, including a smelting furnace and a connecting box, the connecting box is fixedly installed on the top of the smelting furnace and connected to the smelting furnace, and the side wall of the smelting furnace is provided with a slag outlet near the bottom. The utility model first screens the smaller industrial silicon through the first sieve plate arranged inside the connecting box, and then discharges it by the first guide plate. The unscreened industrial silicon will enter the second sieve plate, and the second sieve plate will be used to make the industrial silicon that meets the size fall into the smelting furnace. The oversized industrial silicon will be crushed by the crushing mechanism, and the crushed industrial silicon will enter the inside of the circulation mechanism, and be transported to the top of the connecting box by the circulation mechanism, so as to re-screen the crushed industrial silicon, and then realize the screening of both larger and smaller industrial silicon, so that the size of the industrial silicon entering the smelting furnace is more in line with the requirements.
