Abstract
The utility model is related to a kind of preparation facilities of nickel-cobalt-manganese ternary presoma, and including reaction kettle, the reaction kettle is communicated with two liquid caustic soda inlet tubes and a metal salt inlet tube, wherein liquid outlet of the liquid outlet of a liquid caustic soda inlet tube higher than another liquid caustic soda inlet tube.The utility model uses one high and one low two liquid caustic soda inlet tubes, a wherein liquid caustic soda inlet tube is mainly responsible for the pH value for adjusting whole system, another liquid caustic soda inlet tube is mainly responsible for the direct synthetic reaction with ammonium hydroxide and metal salt, since the liquid caustic soda amount for directly participating in reaction is reduced, local pH is lower, new nucleus once being formed, all can be with than significantly more quickly speed be grown up rapidly originally, so as to achieving the purpose that significantly reduce nucleus.
Description
Technical field
The utility model is related to the preparation facilities of nickel-cobalt-manganese ternary presoma.
Background technology
Nickel-cobalt-manganese ternary material is widely used in the lithium-ion electric of digital electronic goods, electric tool, electric bicycle etc.
Chi Shang.The production method of nickel-cobalt-manganese ternary precursor is mainly added in reaction kettle made simultaneously using metal salt, liquid caustic soda, ammonium hydroxide at present
Standby generation.In continuity method preparation process, due to discharging in feed liquor so that residence time of the material in reaction kettle each not phase
Together, so as to produce the normal distribution of the size particles of final products.But during follow-up sintering, nucleus（Also minimum is cried
Grain）Burning is susceptible to, thus is that positive electrode manufacturer is unwilling to see.Precursor manufacturer is generally using filter cloth during filtering
Exhausting separates part nucleus when wearing filter or drying, though the requirement of positive electrode manufacturer can be met（3 μm of D0 ＞）, but in this way must
Loss of material can so be led to, yield declines, and so as to cause cost increase, this is also current unavoidable main stream approach.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of nickel-cobalt-manganese ternary forerunner that nucleus can be reduced in preparation process
The preparation facilities of body.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of system of nickel-cobalt-manganese ternary presoma
Standby device, including reaction kettle, the reaction kettle is communicated with two liquid caustic soda inlet tubes and a metal salt inlet tube, wherein a liquid
The liquid outlet of alkali inlet tube is higher than the liquid outlet of another liquid caustic soda inlet tube.
Preferably, being provided with two layers of stirring slurry up and down in the reaction kettle, wherein liquid caustic soda inlet tube goes out
Liquid mouth is close to upper strata stirring slurry, and the liquid outlet of another liquid caustic soda inlet tube is close to lower floor's agitating paddle.
Preferably, the liquid outlet of another liquid caustic soda inlet tube is concordant with the liquid outlet of metal salt inlet tube.
Preferably, the reaction kettle is also communicated with ammonium hydroxide inlet tube.
As can be known from the above technical solutions, the utility model uses one high and one low two liquid caustic soda inlet tubes, wherein a liquid caustic soda
Inlet tube is mainly responsible for the pH value for adjusting whole system, and another liquid caustic soda inlet tube is mainly responsible for direct with ammonium hydroxide and metal salt
Synthetic reaction, since the liquid caustic soda amount for directly participating in reaction is reduced, local pH is lower, once being formed new nucleus, all can with than
Originally significantly more quickly speed is grown up rapidly, so as to achieve the purpose that significantly reduce nucleus.
Description of the drawings
Fig. 1 is a kind of structure diagram of preferred embodiment of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with Fig. 1, in the illustrative examples and explanation of this utility model
For explaining the utility model, but it is not intended to limit the scope of the present invention.

Standby device, including reaction kettle 1, the reaction kettle is communicated with two liquid caustic soda inlet tubes 2 and a metal salt inlet tube 3, two liquid
Alkali inlet tube can be passed through liquid caustic soda into reaction kettle, and metal salt inlet tube can be passed through metal salt into reaction kettle；A wherein liquid caustic soda
The liquid outlet of inlet tube is flowed into from a wherein liquid caustic soda inlet tube in reaction kettle higher than the liquid outlet of another liquid caustic soda inlet tube
The pH value of entire reaction system is adjusted in liquid caustic soda, and the liquid caustic soda flowed into reaction kettle from another liquid caustic soda inlet tube can be with ammonium hydroxide and gold
Belong to salt and directly carry out synthetic reaction, realize the preparation of nickel-cobalt-manganese ternary presoma.
Preferably, be provided in the reaction kettle up and down two layers of stirring slurry 4, reaction solution is stirred, it is described its
In a liquid caustic soda inlet tube liquid outlet close to upper strata stirring slurry, the liquid outlet of another liquid caustic soda inlet tube is stirred close to lower floor
Paddle so that solution is more uniform；The liquid outlet of another liquid caustic soda inlet tube is concordant with the liquid outlet of metal salt inlet tube, can
Ensure that reaction is quickly carried out in reaction kettle lower part.The reaction kettle of the utility model is also communicated with ammonium hydroxide inlet tube 5, passes through ammonia
Water inlet tube can be passed through ammonium hydroxide into reaction kettle.
The utility model uses four inlet tubes, it can be achieved that liquid caustic soda, metal salt, ammonium hydroxide while conveys, and improves production effect
Rate, while two liquid caustic soda inlet tubes of height are utilized, the nucleus in reaction process is not only can obviously reduce, can also make to synthesize
Journey D0, using subsequent ageing process, can allow D0 to be increased to 3 μm or more at least more than 1.5 μm.
The technical solution provided above the utility model embodiment is described in detail, used herein specifically
A example is expounded the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to help
Assistant solves the principle of the utility model embodiment；Meanwhile for those of ordinary skill in the art, implement according to the utility model
Example, the there will be changes in specific embodiment and application range, in conclusion the content of the present specification should not be construed as
Limitation to the utility model.
