In summary:The agitating device of a kind of li-ion electrode materials carbon encapsulated material described in the utility model, in life Water or organic solvent addition are injected into mixing device by the water inlet of mixing device during production, thereafter by transition metal Oxide and graphene are spilt into mixing device by the dog-house of mixing device respectively, obtain being modified addition by the way that liquid phase is compound Agent precursor liquid, then by water pump by property-modifying additive precursor liquid along pipeline is to the first feed pipe 111 and enters In one reactor 11, metatitanic acid negative material is put into the first reactor 11 by feed hopper 114 in the environment of stirring, in electricity Under machine 1c drive, the pusher blade 1d of the first reactor 11 is stirred the mixture for, and pushes away mixture to its direction of propulsion Move to the first discharge nozzle 112, stirring is to after certain time, and the magnetic valve 14 of the first discharge nozzle 112 is opened, mixture passes through the Entered after one discharge nozzle 112 and the second feed pipe 121 in the second reactor 12, and along the pusher leaf of the second reactor 12 Mixture is pushed on the second discharge nozzle 122 by piece 1d direction of propulsion, and the magnetic valve 14 of the second discharge nozzle 122 is opened, mixing Thing after the second discharge nozzle 122 and the 3rd feed pipe 131 by entering in the 3rd reactor 13, and along the 3rd reactor 13 Mixture is pushed on the 3rd discharge nozzle 132 by pusher blade 1d direction of propulsion, mixture along the 3rd discharge nozzle 132 most Fall to eventually on conveyer belt 22;And, it is necessary to open the water valve being located on the kettle cover 1b of the first reactor 11 at any time in whipping process 113 collect spiece, and the pH value of mixture is detected in real time, and add ammoniacal liquor in good time to being adjusted, and change titanium The surface nature of sour lithium.
Mixture enters from the charging aperture 2d of body of heater 21 to be come out along burner hearth from discharging opening 2e, in being conveyed through for conveyer belt 22 Cheng Zhong, sequentially passes through dry section 2a, high-temperature region 2b and cooling zone 2c, the electric furnace heating wire that the burner hearth high-temperature region 2b is set is in high-temperature region The high-temperature region 2b domains of 200~500 DEG C of 2b formation;Distribution water pipe in body of heater 21, after water flowing, current reduce cold by cooling zone 2c But the temperature of area 2c burner hearths, after by high-temperature region 2b, water is heated using high-temperature region 2b waste heat, when heating after flow to drying The temperature in the burner hearth of dry section 2a parts is increased to the temperature less than high-temperature region 2b, the burner hearth of dry section 2a parts after area 2a Interior temperature is 80~150 DEG C;Mixture obtains crude product after being dried at a temperature of dry section 2a is at 80~150 DEG C, and crude product passes through High-temperature region 2b, is calcined in the case of 200~500 DEG C of high temperature, and is finally come out of the stove by cooling zone 2c and obtain material, cooling zone 2c It is that inert atmosphere protection is used in order to prevent the oxidation of the material during coming out of the stove, and in burner hearth, it is ensured that carbon contains in material Amount, final material fortune extends material mouth 2e and is transported out outside body of heater 21, and falls to the self-emptying grinder 3 of the lower section of conveyer belt 22 It is interior, the polished lithium battery graphite-doping lithium titanate anode material for finally giving carbon coating.
In large-scale production process, property-modifying additive precursor liquid is directly mixed with metatitanic acid negative material, obtained Batch mixing can directly dry sintering, in an automated manner improve material prepare repeatability, reduce human factor cause Error, the ball material separation process in later stage is reduced compared with ball-milling method.And material modified and titanium is improved in heating Combination between sour lithium, is prepared simply, with low cost, and the high rate performance of lithium titanate material is significantly improved.Equipment production is simple, Operation is convenient.
And in process of production, crude product needs the roasting of 0.5~3 hour of carry out at a high temperature of 200~500 DEG C, because This described conveyer belt 22 is that interval is operated, and the disjunction mechanism 6 of the side of the 3rd discharge nozzle 132 is used for the blanking for controlling mixture, After the cylinder 62 of disjunction mechanism 6 controls disjunction lock about 63, and continuous discharge is changed into intermittent take-off, and mixture is by square tube 61 Pork-pieces blocks can be formed, is conducive to follow-up high-temperature roasting.
Also because crude product needs the roasting by 0.5~3 hour, the utility model is provided with the first reactor 11st, the second reactor 12 and the 3rd reactor 13, compared to single reactor, needed in whipping process shut down wait.It is logical First reactor 11, the second reactor 12 and the UNICOM of the 3rd reactor 13 are controlled first by piping respectively with magnetic valve 14 The discharging of reactor 11, the second reactor 12, the mode of multiple reactor stirrings, feeds, stirring, discharging can be carried out simultaneously, Ensure the continuity of follow-up drying and sintering process, and wait need not be shut down, be i.e. while the 3rd reactor 13 discharges, first is anti- Kettle 11 is answered to be fed, advance stirring operation, while the 3rd reactor 13 completes to discharge, the second reactor 12 is completed subsequently Stirring, prepares discharging.
Accordingly, the stair 5 in the utility model are arranged at the first reactor 11 of ladder pattern distribution, the second reactor 12 With the side of the 3rd reactor 13, the table top of stair 5, which is used to manually stand, carry out maintenance overhaul to the corresponding reactor of each level, And positioned at the superiors workbench 51, then for placing material collection raising middle flask, by material conveyer belt 7 by metatitanic acid negative material from On ground transport to workbench and fall within material collection raising middle flask, then by manually leading to the metatitanic acid negative material in material collection raising middle flask Feed hopper 114 is crossed to put into the first reactor 11.
The corresponding length of body of heater 21 of the present utility model can be lengthened, and be made while the amount for carrying out the crude product of high-temperature roasting increases Plus, it is further for crude product by high-temperature region 2b time just reduce that conveyer belt 22 intermittently operates in the range of, thus when Between, increase output.Now by the way that the metatitanic acid negative material in material collection raising middle flask manually is put into first by feed hopper 114 Subsequent production speed is not just caught up with reactor 11, the top of material transferring band is directly arranged to the top of feed hopper 114, Accelerate the input speed of metatitanic acid negative material.
The above, is only preferred embodiment of the present utility model, and not technical scope of the present utility model is made Go out any limitation, thus it is every any trickle amendment made according to technical spirit of the present utility model to above example, equivalent Change and modification, in the range of still falling within the technical solution of the utility model.
