Description

technical field [0001] The invention belongs to the preparation equipment of solar silicon chips, in particular to a sintering and anti-light decay integrated machine for processing solar silicon chips. Background technique [0002] As we all know, in the production of silicon wafers for crystalline silicon solar cells, after the silicon wafers are printed, it is necessary to dry and sinter the silicon wafers with the slurry through the sintering furnace, and then activate the anti-light decay ability of the silicon wafers through the anti-light decay furnace . Among them, the sintering furnace usually includes a drying zone, a sintering zone and a cooling zone. The anti-light attenuation furnace usually includes a light source box, a transmission device and a heating device. The light source box is provided with a lamp tube, a condenser and a centrifugal fan. [0003] Among them, in the sintering furnace, since the silicon wafers with silver paste are dried, more organic ...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to provide a sintering and anti-light decay integrated machine for processing solar silicon wafers, so as to solve the problem of insufficient combustion of organic waste gas in the combustion tower in the sintering furnace in the prior art, the large footprint of the combustion tower, and the sintering section. Waste is not timely, leading to the problem of organic waste accumulation and pollution of silicon wafers; and problems such as poor cooling effect of the cooling device in the anti-light decay furnace
