High-yield environment-friendly automatic dead-burnt magnesia shaft kiln and production method
The invention belongs to the technical field of refractory material production devices and particularly relates to a high-yield environment-friendly automatic dead-burnt magnesia shaft kiln and a production method. The shaft kiln comprises a feeding system, a shaft kiln body and a discharging system, wherein the shaft kiln body is divided into a preheating zone, a firing zone and a cooling zone from top to bottom; a preheating zone air outlet is formed in the kiln wall of the shaft kiln body of the preheating zone; a cooling zone air inlet is formed in the kiln wall of the shaft kiln body of the cooling zone; the preheating zone air outlet is connected with the cooling zone air inlet through a pipeline; a circulating fan is arranged on the pipeline to feed hot air of the cooling zone intothe preheating zone to preheat raw materials; and a natural gas combustion system is arranged on the shaft kiln body of the firing zone. Natural gas is used as fuel, environmental pollution is reduced, the structure of the kiln body is changed, and energy consumption is reduced.
本发明属于耐火材料生产装置技术领域，具体涉及一种高产环保型自动化重烧镁砂竖窑及生产方法，竖窑包括上料系统、竖窑本体和出料系统，竖窑本体从上至下分为预热带、烧成带和冷却带，在预热带的竖窑本体窑壁上，设有预热带出风口，在冷却带的竖窑本体窑壁上，设有冷却带进风口，预热带出风口与冷却带进风口通过管路连接，并且在管路上设有循环风机，将冷却带的热风送入预热带预热原料；烧成带的竖窑本体上设有天然气燃烧系统。本发明以天然气为燃料，降低环境污染，并且改变了窑体结构，降低了能源消耗。
