Description

Technical Field

[0001] The utility model belongs to the technical field of tempered glass processing devices, in particular to a photovoltaic tempered glass preheating furnace. Background Art

[0002] Photovoltaic tempered glass is ultra-white glass, also known as colorless glass, high-transparency glass, and low-iron glass. It has high light transmittance and high transparency. The light transmittance determines the quality of the glass. The light transmittance of float glass is 86%, while the light transmittance of ultra-white glass can reach more than 92%. Photovoltaic tempered glass needs to be preheated in a preheating furnace during the processing process. The preheating process can increase the surface temperature of the glass when it enters the heating section, so that it can quickly reach the tempering temperature and reduce deformation caused by temperature changes. The main purpose of preheating is to increase the base temperature of the glass, shorten the time cycle required in the processing and production process, and then improve the product yield, increase production capacity and glass yield.

The preheating furnace for physical tempering of glass, by setting a preheating furnace with convection effect, makes the heat fully play a role through convection effect, makes the tempered glass fully preheated, improves the utilization rate of heat, and saves energy.

[0004] In the above patent, the rack for placing the tempered glass plate is directly arranged inside the preheating chamber of the preheating furnace. Therefore, before preheating the tempered glass, the tempered glass needs to be placed on the corresponding rack, and the preheating can only be started after the placement is completed, which reduces the efficiency of the preheating furnace. In addition, the size of the tempered glass plate that can be placed on the rack is relatively single, and it cannot meet the preheating requirements of tempered glass plates of different sizes.

[0005] Therefore, a photovoltaic tempered glass preheating furnace is urgently needed to solve the above technical problems. Utility Model Content
