快开型蒸压釜
本专利技术涉及成型制品加工设备领域。
技术介绍
“蒸压加气混凝土砌块”是以硅质材料(砂、粉煤灰及含硅尾矿等)和钙质材料(石灰、水泥)为主要原料,掺加发气剂(铝粉),经加水搅拌制成加气混凝土,然后由化学反应形成孔隙,通过浇注成型、预养切割、蒸压养护等工艺过程制成的多孔硅酸盐制品。蒸压加气混凝土砌块是一种轻质多孔、保温隔热、防火性能良好、可钉、可锯、可刨和具有一定抗震能力的新型建筑材料,是一种变废为宝的新型墙体材料。蒸压养护,即将加气混凝土放入蒸压釜中,然后通入高温高压水蒸汽,根据工艺要求的升温、升压、恒压和降压曲线,对产品进行高温高压养护。现有的蒸压养护工艺具有如下缺陷或不足:在蒸压养护结束时,釜内温度在100℃左右,有大量水蒸气存在,如果立即打开釜门快速排出釜内热量,则釜内的水泥制品温度也会急剧下降,且温度很不均匀。同时会导致水泥制品边部和表层水分急剧挥发,水泥制品在温度应力和干缩应力共同作用下,容易产生细小的裂纹或开裂,影响制品强度和性能,甚至会造成大量废品的产生;而如果采取缓慢打开釜门逐步降低釜内温度或关闭釜门自然降温的方式,则又会大大延长蒸压釜的运作周期,降低了生产效率,并且,如果蒸压釜内温度和湿度控制不当,水泥制品仍会有开裂的可能。
