Large-tonnage one-kiln eight-line thin photovoltaic glass melting furnace

Abstract

The invention discloses a large-tonnage one-kiln eight-line thin photovoltaic glass melting furnace which comprises a feeding tank, a melting furnace, a regenerative chamber, a small furnace, a neck, a cooling part, a branch passage, a calendering unit and a calender maintenance platform. The branch passages are symmetrically arranged on the two sides of the cooling part so that the molten glass flow operation mode of the melting furnace and the cooling part is closer to a large-tonnage one-kiln one-line mode, the mode has little influence on the melting, clarification and homogenization process of the melting part, and the optical quality and the mechanical strength of a product are improved. The structural mode also reduces the glass liquid flow reversing times, and the liquid flow is smoother so that the turbulence is reduced. Besides, according to different heat dissipation degrees of the molten glass in the flowing process, in order to guarantee relative balance of the temperature and the quality of the molten glass at the outlets of the branch passages, the distances from the neck outlets to the outlets of the branch passages are set to be unequal. Due to the arrangement of the non-equal-length branch passages, the outlet positions are not concentrated, the operation space temperature of the calendering forming position is effectively reduced, and the calender replacement operation difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaic glass, in particular to a large-tonnage thin-type photovoltaic glass melting furnace with one furnace and eight lines. Background technique [0002] With the rapid transformation of photovoltaic modules from traditional single-glass modules to double-glass and double-sided power generation modules, in order to achieve lightweight modules, the thickness requirements of photovoltaic glass modules have also rapidly changed from 3.2mm to 1.6-2.0mm. Large-tonnage furnaces have large output and obvious energy-saving effects, but at present, the large-tonnage one-kiln four-line photovoltaic glass production line cannot produce 2.0mm thin photovoltaic glass due to rigid conditions such as furnace structure, technology and equipment, while small-tonnage production lines The production line can produce 2.0mm thin photovoltaic glass, but the output is low, the unit energy consumption is huge, and the co...
