Abstract
The invention provides an airflow circulating device of a solar cell sintering device. The airflow circulating device can prevent cells from being oxidized in the sintering process. A buffering area is arranged between a drying area and a sintering area, and the buffering area is space formed by arranging the sintering area apart from the cooling area by a certain distance. The drying area is composed of three hearth units and comprises three temperature areas. The sintering area is composed of six hearth units and comprises six temperature areas. The hearing units are hearths which are arranged in a vertically symmetric mode, and separating plates are arranged between different hearth units. The airflow circulating device further comprises a nitrogen machine, a first gas supply pipeline is arranged on the nitrogen machine, and the first gas supply pipeline conveys nitrogen into the six hearth units of the sintering area. The nitrogen of the sintering area is discharged out of the buffering area and the cooling area. A second gas supply pipeline is arranged on the nitrogen machine and conveys the nitrogen into the three hearth units of the drying area, and the nitrogen of the drying area is discharged out of the buffering area and an inlet of the sintering furnace.
