Description

Technical Field

[0001] The utility model relates to the technical field of steam heating, in particular to a steam heating device for drying silicon blocks. Background Art

[0002] Silicon block, also known as silicon single crystal block or silicon single crystal rod, is a block material composed of silicon dioxide (SiO2) formed after high-temperature melting. It is one of the important raw materials in the electronics industry and photovoltaic industry and has broad application prospects. The chemical properties of silicon block are relatively active. It can combine with various elements such as oxygen at high temperature, but it is insoluble in water, nitric acid and hydrochloric acid, but soluble in hydrofluoric acid and alkali solution. Silicon block drying is an important step in the silicon block processing process. It is usually used to remove water and moisture in silicon blocks to ensure the quality and performance of silicon blocks. These water and moisture may have a negative impact on the performance and quality of silicon blocks. Silicon block drying is an important step to ensure the stable performance of silicon blocks and improve product quality and production efficiency. During the drying process, temperature and time need to be strictly controlled to avoid adverse effects on silicon blocks.

[0003] In the existing scheme, during the drying process of silicon blocks, the silicon blocks may encounter local overheating or insufficient heating, which will affect the quality of the silicon blocks used subsequently. For this reason, we propose a steam heating device for drying silicon blocks. Utility Model Content

[0029] Further, a plurality of fixing columns 12 are installed at the bottom end of the outer shell 4, and the plurality of fixing columns 12 are connected to a connecting plate 11.

The toothed ring 10 drives the inner shell 14 to rotate. While the inner shell 14 rotates, it drives the internal stirring blade 16 to rotate. The stirring blade 16 is heated by the hot steam and then evenly stirs the silicon blocks. The silicon blocks move along the track of the stirring blade 16. The external air flows between the multiple fixed columns 12 to take out the generated gas. The connecting disk 11 and the protective plate 18 prevent the silicon blocks from falling during the heating process. The silicon blocks flow out between the fixed columns and reach the top of the top seat, and then reach the inside of the collecting container along the track of the inclined groove 19.
