Filter pressing system for ultra-clean coal slurry

The utility model discloses an ultra-clean coal slurry filter pressing system which comprises an ultra-clean coal slurry storage device and a feeding pump which are communicated through a pipeline, the other end of the feeding pump is communicated to a filter press through a three-way device, and the other end of the three-way device is communicated to the ultra-clean coal slurry storage device through a backflow pipeline. By utilizing the filter pressing system for the ultra-clean coal slurry, the water content of a filter cake can be reduced, the filter cake after filter pressing is not sticky, the filter cloth does not need to be manually cleaned, and deposition in a pipeline is avoided. 本申请公开了一种超洁净煤浆液的压滤系统，包括利用管道连通的超洁净煤浆液储存装置和给料泵，所述给料泵的另一端利用三通装置连通至压滤机，所述三通装置的另一端利用回流管道连通至所述超洁净煤浆液储存装置，利用上述超洁净煤浆液的压滤系统，能够降低滤饼的含水量，压滤后滤饼不发粘，滤布无需人工清洗，避免在管道中沉积。
