一、我国圆盘式真空过滤机脱料方式的现状与国外的差距随着选煤工业的发展,我国圆盘式真空过滤机也发生了很大的变化。但是,在脱料方式上始终还保持了五十年代的吹风脱料。这种脱料方式,脱料效率低(平均50%左右),使物料在过滤机中造成往复循环,严重地影响了设备单位面积的处理量,生产效率大大降低。因此我们在建厂设计中,选择过滤机的台数较多,各种附属设备、厂房面积、管理人员也相应的增加,也加大了动力消耗和设备维修量,使工程投资和生产维修费大大提高,这对企业的经济效益非常不利。这一情况,国外
First, China disc vacuum filter strip the status quo and the gap with foreign With the development of coal preparation industry, China’s disc-type vacuum filter has undergone great changes. However, in the way of stripper has always maintained the fifties hair removal. This de-feeding way, the de-feeding efficiency is low (about 50% on average), causing the material to cause reciprocating cycle in the filter, which seriously affects the handling capacity per unit area of the equipment and the production efficiency is greatly reduced. Therefore, we are in the design of the plant, the number of filters to choose more, a variety of ancillary equipment, plant area, managers also increased accordingly, but also increased the amount of power consumption and equipment maintenance, engineering investment and production maintenance costs greatly Improve, it is very unfavorable to the economic benefits of enterprises. This situation, abroad
