Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic glass cooperation mixing equipment technical field especially relates to a kind of photovoltaic glass cooperation material mixing equipment and mixing system. BACKGROUND

[0002] The technical development path of photovoltaic glass batching equipment has undergone a transformation from traditional small-scale, low efficiency to modernization, large-scale and high efficiency. Early photovoltaic glass production mostly used horse's hoof flame kiln, with small daily melting capacity, low yield, short residence time of glass liquid in the kiln, resulting in more micro-bubbles and poor glass uniformity. With the progress of technology, almost all newly built kilns have switched to full-oxygen horizontal flame kilns, with significant improvements in various performance indicators. The contact area between the glass liquid and the pool wall electric melting brick is reduced, the defects of non-melted substances on the output glass plate are significantly reduced, the maximum glass liquid drawing capacity is greatly increased, effectively reducing the line bubbles and improving the glass yield.

[0003] Currently, the technical status of photovoltaic glass batching equipment shows a trend of large-scale kiln and more energy-saving and safe eight-line technology per kiln. Large-scale kilns can reduce raw material and fuel consumption and reduce amortization costs, thereby improving profitability. In addition, the structural optimization of photovoltaic modules has also had a profound impact on the development of the photovoltaic glass industry. Photovoltaic glass is gradually developing towards large size and thinness to meet the demand of module manufacturers for advanced photovoltaic products with higher quality, higher efficiency and lower cost. The penetration rate of ultra-thin 1.6mm photovoltaic glass is increasing, but the impact strength and bending strength of super-white calendaring glass will decrease, and the key technologies of formula, melting, forming and annealing of 1.6mm ultra-thin photovoltaic glass need to be overcome.

[0004] Despite the significant progress in photovoltaic glass batching equipment technology, there are still some deficiencies. First, after each raw material enters the weighing belt, the material is concentrated and dropped to a certain position on the belt, which causes the material to be too concentrated, the uniformity of the batch fluctuates greatly, affects the consistency of the chemical composition of the glass, and further affects the melting and quality of the glass in the kiln. Second, the unevenness of the batch may cause uneven heat transfer and material exchange in the local area of the kiln, uneven melting, and easily produce defects, affecting the optical performance, mechanical properties and other quality indicators of photovoltaic glass. In addition, the batch with different composition stability entering the kiln will cause fluctuations in the process parameters such as kiln charging stability, kiln melting temperature and kiln liquid level height, directly affecting the melting quality of the overall glass kiln, seriously affecting the product quality fluctuation of the whole production line, causing quality accidents of raw products, and affecting the cycle for a long time.
