Description

Technical Field

[0001] The utility model belongs to the technical field of single crystal furnaces, in particular to a single crystal furnace feeder. Background Art

[0002] As a clean energy source, the photovoltaic field has achieved rapid and high-quality development. Monocrystalline silicon rods, the core product of solar cell modules, have seen significant large-scale expansion and production increase in recent years. The main cost of silicon rods comes from native polysilicon materials, and the market price of silicon materials directly affects the benefits of silicon rod companies. Due to the hot industry, various silicon rod companies have increased production and expanded production at a fast pace, while silicon material production companies have a long expansion cycle, resulting in a situation where silicon materials are difficult to obtain and silicon material prices remain high. The emergence of granular silicon has alleviated this situation. Granular silicon has a fast production speed, high output, and low price. After its appearance, it has directly become the new favorite of the industry.

[0003] According to a disclosed single crystal furnace feeder (publication number: CN 218404497 U), it includes: a first feeding tube, an isolation tube, a bottom cone and a second feeding tube; the first feeding tube forms a first cavity, and the second feeding tube forms a second cavity. Through the arrangement of the above structure in the above application, this scheme can completely avoid the mixing of granular silicon and dense native polysilicon in the feeder, and there will be no material jamming accident after mixing during the feeding operation. The granular silicon is not in direct contact with the high-temperature silicon liquid, which solves the problem of silicon jumping and greatly improves the crystal survival rate after using granular silicon. It reduces costs and increases production. However, the above application cannot be docked and fixed with the single crystal furnace mouth, and is prone to side tilting during use, which may cause raw material leakage and is not very practical.
