Description
Technical field
The present invention relates to a kind of thickener, more precisely, being a kind of medicament dilution device of high-efficiency concentrator.
Background technology
Thickener is mainly made of being to realize separation of solid and liquid, and its important indicator is underflow pulp density and overflow water turbidity, extensively
It is general for concentrate, Tailing thickening and wastewater treatment etc..High-efficiency concentrator compared with common thickener, with unit area treating capacity
Greatly, the advantages of saving floor space and good overflow water index.
General high efficiency thickener improves material sinking speed by flocculant, molten using this macromolecular organic compound
Strand and ore particle suction-operated after water, material form floc sedimentation and accelerate settlement to act on.Flocculant is mainly anion
The polyacrylamide of type powdery, its molecular number can reach more than 300 ten thousand, and bridge chain, " seizure " solids are formed in water
It is allowed to form flocculation granule, accelerates sedimentation.Flocculant usage depends on material properties, and general dry material consumption per ton is several grams
To tens grams.Flocculant must be diluted to finite concentration when preparing, and this is critically important step when using.
Traditional flocculant dilution is that flocculant dry powder is added directly into opened type tank diameter, as requested
Drug concentration, Jiang Xinshui is stirred in adding to tank diameter, is pumped into storagetank by metering after stirring, then by frequency conversion
Measuring pump delivers medication into the chemical feeding points of concentrator.
A kind of chemicals dosing plant of patent and its application method (publication number of Ling You Shanghai Chengtou Sewage Management Co., Ltd application
