细粉料重力式均化料仓的研究与应用

Research and Application of Gravity Homogenization Silo of Fine Powder

重力式均化料仓已广泛应用于石化行业的大颗粒塑料粒子的掺混,应用于细粉料的均化则很少。根据细粉料流动特点,结合试验台测试,研究了重力式均化料仓内细粉料的流动形态,均化管的开孔形状、大小、规律,以及防粉料架桥的措施与构件等。该试验研究结果用于指导电解二氧化锰粉料工业生产的均化料仓设计,取得了很好的效果。

The gravity homogenization silo is widely used for blending of large plastic particles in the petrochemical industry,but it is rarely used for homogenization of fine powder.According to the flow characteristics of fine powder,and based on bench test,study was conducted on the flow pattern of fine powder in the gravity homogenization silo,the opening shape,size,pattern of homogenization tubes,and the measures and structural members of powder-proof trays.The test results are used to guide the design for the homogenization silo in the industrial production of powder of electrolysis manganese dioxide,and good effects are achieved.
