螺旋振动水玻璃旧砂再生的研究

The Study on Used-sodium Silicate Sand Reclamation by Spiral Vibrating

通过对螺旋振动水玻璃旧砂再生大量实验结果的研究分析,认为螺旋振动水玻璃旧砂再生是在剪切力、摩擦力和冲击力等的综合作用下进行的,Na_2O去除率可达36.95%,预处理后可达60.56%,Na_2O残留量分别为0.7%和0.44%,均低于0.8%的限量要求。螺旋振动水玻璃旧砂再生机集破碎、再生,冷却等于一体,是一种简单有效的再生设备,本文为设计螺旋振动水玻璃旧砂再生机提供了实验依据。

By means of studing and analysing a lot of experiments results of spirall vibrating used-sodium-silicate sand reclamation, the conclusion is drawn that used-sodium silicate sand in the spiral vibrating is reclaimed by the combination of shear force, scrape force, impact force and so on. The Na_2O removal rate in the reclaimed sand is 36.95% and is up to 60.56% after pretreating. The Na_2O retained amount is 0.7% aud 0.44% respectively, and is lower than the limit of 0.8%. The spiral vibrating used-sodium silicate sand reclamation machine has the roles of breaking, reclaiming and cold, it is a simple and effective reclamation equipment, this paper provides experimenting basis for designing spiral vibrating used-sodium silicate-sand reclamation equipment.
