Description
Technical field
It the utility model is related to a kind of nickel-cobalt-manganese ternary hydroxide washing system.
Background technology
At present generally using sulfuric acid system nickel, the raw material of cobalt, manganese as ternary material battery in industry, its building-up process can not
What is avoided introduces the impurity elements such as sulfate radical, and with industry development, sulfate radical all brings certain negative shadow to capacity, security
Ring, current battery manufacturer requires that the control of sulfate radical content mass percent is below 0.4% in positive electrode.
Further to reduce sulfate radical content, ammonium hydrogen carbonate, liquid caustic soda etc. is used to be used as lotion in industry, industry generally uses
Plate filter and centrifuge combination are washed or washed using two desk centrifuge modes, Chinese patent
201310278462.5 disclose a kind of preparation method of low-sulfur ternary precursor, wherein an equipment first consolidates synthetic slurry
Liquid is separated, and then discharging and carries out pulp, and storage tank heating alkali leaching immersion is transferred to after pulp, is squeezed into addition after temperature reaches requirement
One desk centrifuge or plate filter washing, its washing procedure is long, process is complicated, and inter process linking causes ammonia to overflow, existing
Field environment is poor, and slurrying process needs extra washing pure water, while finds to be easily destroyed original hydroxide in slurrying process
Spheric granules, causes to increase than surface, the negative effects such as tap density declines.
Utility model content
The purpose of this utility model is that a kind of collection mother liquor separation, alkali cleaning, washing are provided the problem of presence for prior art
The nickel-cobalt-manganese ternary hydroxide washing system being integrated with drying step.
Concrete technical scheme of the present utility model is as follows：
A kind of nickel-cobalt-manganese ternary hydroxide washing system, including centrifuge, in addition to slurry storage tank, high alkali liquid storage tank and
Hot pure water storage tank, cleaning sprayer is uniformly placed with the centrifuge inwall, high alkali liquid storage tank and hot pure water storage tank pass through pipeline
Connected with cleaning sprayer, the slurry storage tank is connected by pipeline with centrifuge；
Magnetic drive pump, flowmeter and pneumatic operated valve, high alkali liquid storage are provided with pipeline between the slurry storage tank and centrifuge
Measuring pump, stop valve and pneumatic operated valve are provided with pipeline between groove and cleaning sprayer, between hot pure water storage tank and cleaning sprayer
Pipeline on be provided with magnetic drive pump and pneumatic operated valve；
The connection end of the slurry storage tank and centrifuge is provided with swash plate distributing device.
The utility model has the advantages that：
Slurry storage tank, high alkali liquid storage tank, hot pure water storage tank and centrifuge collection are combined into set of system by the utility model, from
Mother liquor separation, alkali cleaning then can be achieved in scheming, washing and drying step, process take short, and process is simple.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of nickel-cobalt-manganese ternary hydroxide washing system as shown in Figure 1, including centrifuge 1, in addition to slurry storage tank 2,

Magnetic drive pump 6 and pneumatic operated valve 8 are provided with road, the connection end of the slurry storage tank 2 and centrifuge 1 is provided with swash plate distributing device 11.
Specific work process of the present utility model is as follows：
The nickel-cobalt-manganese ternary slurry that reactor synthesizes is stored in slurry storage tank 2, passes through the magnetic drive pump 6 of slurry storage tank 2
Centrifuge 1 is delivered to, flowmeter 7 is used to detect slurry flow, and swash plate distributing device 11 is used to slurry being evenly distributed in centrifuge 1
It is interior；Centrifuge 1 starts to be dehydrated to slurry, after being dehydrated 120-300s, opens the gas of high alkali liquid storage tank 3 and hot pure water storage tank 4
Dynamic valve 8, is mixed alkali lye and hot pure water by the measuring pump 9 of high alkali liquid storage tank 3 and the magnetic drive pump 6 of hot pure water storage tank 4, and pass through
Cleaning sprayer 5, which sprays, carries out alkali cleaning；After alkali cleaning terminates, the pneumatic operated valve 8 of high alkali liquid storage tank 3 is closed, hot pure water storage tank 4 is to centrifuge
1 conveying hot pure water is washed, and after completing washing, closes the pneumatic operated valve 8 of pure water storage tank 4, centrifuge 1 carries out drying operation.
