Abstract
The utility model relates to a crystallization reaction and system of unloading, including reation kettle, there is a storage tank on reation kettle's lateral wall upper portion through the tube coupling, connects filter equipment under the storage tank, isolates the crystal with the solution that the reaction is spilled over, and filtrating is returned the reation kettle bottom through the pump and is constituted the circulation. The utility model discloses a set up this branch road of storage tank - filter equipment, can not influence going on of reation kettle internal reaction in time with reacting the crystal discharge that produces and the ageing of stewing in the liquid, filter equipment can directly be put into by the storage tank to material after the ageing, and filtrating recovery gets into reation kettle and recycles.
Description
Technical field
The utility model relates to a kind of crystallization reaction and discharge system.
Background technology
Comprise the Moist chemical synthesis of the presoma of anode material of lithium battery, all need the reaction condition of the strict hierarchy of control, digestion time is exactly wherein very important one.It directly can have influence on pattern and the granularity of crystal.
This step of ageing do not considered by existing reactor, is substantially all direct discharging or mistake grading once, and proves through experimental study: the still aging time, can impact the shaping of crystal yet.And existing reactor is separated with filter, bring operational inconvenience, be also unfavorable for the control of atmosphere.
Utility model content
The purpose of this utility model is a kind of crystallization reaction of design and discharge system, can the crystallization produced in reactant liquor be discharged in time and carry out ageing separation.
The technical solution of the utility model is: a kind of crystallization reaction and discharge system, comprise reactor, the side wall upper part of reactor is connected with storage tank by pipeline, connects filter under storage tank, the solution that reaction is overflowed is isolated crystal, and filtrate returns bottom reactor through pump and forms circulation.
Described storage tank has valve.
The lower end of described reactor feed pipe exports the pipeline connected higher than reactor side wall upper part.
As improvement, be provided with pH meter probe in reactor, the part that pH meter probe is positioned at reactor is covered by protective cover entirety, and described protective cover is network structure, and protective cover is built-in with screen pack.
Described protective cover is test tube shape.
Described protective cover is made up of high temperature resistant, acid and alkali-resistance material, and the channel floor that pH meter probe is positioned at reactor also covers by screen pack.
As improvement, have agitating device in reactor, paddle is made up of totally four blades of top-bottom cross: under two panels, blade is oppositely arranged, and in two panels, blade is oppositely arranged and intersects with lower blade and staggers, in two panels, blade is mutually vertical, and in two panels, blade and puddler angle are less than 70 °.
As further improvement, under two panels, blade is for agreeing with along being designed to arc under still, and in two panels, blade is Thin Rectangular tabular, and four blade lengths are close to still wall.
As further improvement, in two panels, blade and lower blade intersect and stagger in about 90 °, and in two panels, the angle of blade and puddler is about 45 °.
As improvement, reactor sidewall is provided with hollow cavity, is provided with heating electric resistance silk in chamber.
The utility model be applicable to any needs stir the crystallization reaction affected by pH, can continuous charging react system.The utility model has following beneficial effect:
1) by arranging this branch road of storage tank-filter, can in time the crystal produced in reactant liquor be discharged and carry out still aging, not affect the carrying out of reaction in reactor; Material after ageing directly can put into filter by storage tank, and filtrate recovery enters reactor and recycles;
2) pass through in establish the netted protective cover of screen pack to be covered by pH meter, can prevent crystalline particle from touching Glass Probe, not affect again the detection of pH simultaneously;
3) by upper and lower two-layer stirrer paddle, every layer takes different shapes and angle setting, makes mixing effect better, effectively prevent crystal from luming in kettle, strengthen stirring dynamics, still substance in vivo can be made better balanced, to be sent into this branch road of storage tank-filter;
4) course of work of the good intelligentized control method reactor of the utility model energy, and ensure the service life of smart machine.
