Abstract
This invention provides a silicon powder drying device, relating to the field of silicon powder drying technology. The invention includes a housing, two sealing plates disposed within the housing, a plurality of vertically arranged tubes positioned between the two sealing plates, a feed pipe connected to the top of the housing, and an exhaust assembly located at the top of the housing. The two ends of each tube are connected to the interior of the housing outside the two sealing plates. A heat exchange chamber is formed between the two sealing plates outside the tubes. The outer wall of the housing is provided with a heat exchange inlet pipe connected to the top of the heat exchange chamber and a heat exchange outlet pipe connected to the bottom of the heat exchange chamber. A silicon powder filter is installed within the exhaust assembly, and a first air inlet pipe is connected to the bottom of the housing. This invention features low energy consumption and improved drying efficiency.
