我选煤厂洗末煤系统扩建时,压滤车间使用了3台800m2压滤机(XMZ800/2000箱式压滤机),经过2年运转,存在以下几个问题: (1)拉板机构在卸饼过程中,一开始滤板与滤板之间的卸饼空间有400mm(压紧板油缸行程是800mm),由于拉板的压力较低,且卸过饼的滤板处于松弛状态或者滤板滤布之间有褶皱或夹上煤泥,因此,每次卸饼后的滤板之间有一定的间隙,越是卸到最后,滤板之间的卸饼空间越小,最小时不到200mm,甚
When the coal washing plant was being expanded, the pressure filtration plant used three 800m2 filter presses (XMZ800 / 2000 box filter press). After two years of operation, the following problems existed: (1) During the unloading process, there is a space of 400 mm between the filter plate and the filter plate at the beginning (the stroke of the pressure plate cylinder is 800 mm). Since the pressure of the plate is low and the filter plate disassembled is in a relaxed state or There are folds or clippings of slime between filter cloths, so there is a certain gap between the filter plates after each cake unloading, and the more the unloaded cake lasts, the smaller the unloading cake space between the filter plates is, and the minimum time Less than 200mm, very
