摘　　要：为了提高南桐洗选厂浮选精煤泥回收率,结合当前干坝子厂区入选原煤煤质特点,对比分析了箱式压滤机和盘式加压过滤机的工作原理、结构和工作过程。分析预测表明,箱式压滤机设计结构合理,脱水效率高,在干坝子厂区当前煤质条件下,在浮选精煤泥回收方面具有优势,处理后的浮选精煤水分可达到21%,为压滤设备的选择提供了精准依据。For obtaining a higher flotation concentrate recovery rate, and in light of the property of the raw coal treated at Nantong Plant＇s Ganbazi section, a comparative analysis is made of the working principle, structure and operating process of the recessed-plate filter press and disc pressure filter. Analysis shows that the former is rational in structural design, high in dewatering efficiency, and highly adaptable to the raw coal property. With the use of the filter press, the moisture of flotation concentrate can be lowered to 21%. The study provides a sound basis for optimum selection of filtering equipment.
