Raw material conveying and sampling device for single crystal furnace

Abstract

The invention relates to a raw material conveying and sampling device for a single crystal furnace. The raw material conveying and sampling device structurally comprises an upper layer, a middle layer and a lower layer, wherein the upper layer is a smashing layer, the middle layer is a conveying layer, and the lower layer is a sampling layer; a first discharge port is formed in the bottom of the smashing layer, the smashing layer is communicated with the conveying layer through the first discharge port, sampling ports are formed in the bottom of the conveying layer, and the conveying layer is communicated with the sampling layer through the sampling ports; the sampling layer comprises a sampling box, a vibrating track, a vibration exciter, rollers, first rotating shafts and a first motor, a trough is formed in the surface of the roller, and a third discharge port is formed in the right end of the sampling box. By means of the design, raw materials are sampled and detected in the raw material conveying process, and unnecessary loss caused by mixing of excessive impurities in the raw materials is prevented.

Description

technical field [0001] The invention relates to the field of floor processing, in particular to a raw material conveying and sampling device for a single crystal furnace. Background technique [0002] Single crystal furnace is the necessary equipment in the process of converting polycrystalline silicon into single crystal silicon, and single crystal silicon is the basic raw material in photovoltaic power generation and semiconductor industry. As the key supporting material of the modern information society, single crystal silicon is one of the most important single crystal materials in the world. It is not only the main functional material for the development of computers and integrated circuits, but also the main functional material for photovoltaic power generation and utilization of solar energy.

Problems solved by technology

[0003] Monocrystalline silicon has high requirements on raw materials in the production process. If there are many impurities in the polycrystalline silicon delivered in, the quality of the prepared monocrystalline silicon ingot will be reduced. Therefore, raw materials need to be tested before preparing monocrystalline silicon. Therefore, it is particularly important to design a raw material delivery and sampling device for single crystal furnaces.
