板框式压滤机残渣机内清洗改造

MODIFICATION ON CLEANING RESIDUAL IN PLATE FILTER

板框式压滤机一般都不具备机内清洗功能，如果要求对机内物料进行清洗则必须再次化浆后．进行二次过滤才能做到；本改造目的是使残渣在过滤后期，直搂在压滤机内进行二次清洗，达到清洗残渣，降低含砷，回收有价金属的效果。

Plate filter generally doesn' t have built - in cleaning function, cleaning of material inside the filter can be achieved only after the material is made into slurry and re - filtered. The purpose of this modification is to let residual he re - cleaned directly in the filter after later stage of filtering so as to lower down arsenic content and recover precious metals.
