Degree, improves production efficiency.
Technical solution adopted by the utility model to solve its technical problems is：One kind is produced for ternary material precursor
Proportioner, including storage tank, metering feed bin, delivery pump, dosage bunker, the outlet is connect with feed bin top is measured, defeated
It send and is connect at the top of pump and metering feed bin, the metering bin bottom is connect with dosage bunker；Be equipped in the metering feed bin weighing apparatus,
Top is equipped with deduster, and agitating device and Element detection device are equipped in the dosage bunker.
Preferably, the metering feed bin is taper feed bin.
Preferably, further include Blowing stopper, the metering feed bin is connect by Blowing stopper with dosage bunker.
Preferably, the Element detection device selects icp analysis instrument.
Preferably, the delivery pump selects vacuum pump or vortex pump.
Preferably, the storage tank is three.The outlet is equipped with valve.
The utility model has the beneficial effects that：The utility model selects delivery pump that will prepare three kinds of ternary material precursor
Weighing is transported to metering feed bin to raw metal in proportion, is then placed in dosage bunker and adds water stirring and dissolving, and is filled by Element detection
The content and concentration for setting metal ion in on-line monitoring ternary feed liquid, shorten the dispensing time of ternary feed liquid, improve ternary
The precision of feed liquid, to meet the production requirement of ternary precursor；Automated production is realized simultaneously, improves production effect
Rate.
