Description
Technical field
The present invention relates to a kind of thickener, more precisely a kind of thickener for lithium fluoride or lithium carbonate sinker mother liquor concentrations-centrifugal separation process.
Background technology
After hydrofluoric acid and sinker mother liquor sedimentation lithium fluoride or the centrifugation of lithium carbonate sinker mother liquor, filter press need be adopted again to extrude sinker mother liquor, be separated the lithium fluoride in mother liquor or lithium carbonate.Because mother liquid concentration is lower, generally lower than 0.5%, and containing sodium ion in mother liquor, easy fouling and clogging filter board hole, such that filter press dewatering efficiency is low, weak effect.
Adopt concentrated-centrifugal separation process, by concentration lower than 0.5% mother liquor first concentrate, improve solid concentration, concentrated underflow enters centrifuge again and carries out Separation of Solid and Liquid, and concentrated overflow solids content is low and stable, and overflow mother liquor directly enters mother liquor gathering system.The solid that centrifuge is separated enters product, and liquid returns thickener.Separative efficiency is high, effective, and labour intensity is low.Because sinker mother liquor contains chlorion, fluorine ion etc., corrosivity is strong, and the structure of existing thickener is difficult to meet the demands.The thickener be not suitable at present, even the thickener that stainless steel material makes also easily or is very soon corroded.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art provides one to be applicable to the corrosion resistant special thickener of sinker mother liquor concentrations-centrifugal separation process, and, use corrosion resisting stainless steel strong for corrosivity is also difficult to the sinker mother liquor concentrations met the demands.
