Technical field

The present invention relates to cell size production equipment technology, more particularly to a kind of cell size homogenization system and its Process flow.

Background technique

Currently, with the popularization and application of new energy technology, so that lithium battery is widely used in waterpower, firepower, wind-force and too It is positive can the accumulation power supplies system such as power station, the uninterruptible power supply of post and telecommunications, be especially applied to electric tool, electric bicycle, The various fields such as battery-operated motor cycle, electric car, military equipment, aerospace.The lithium battery for developing large capacity is dynamic as automobile The application of power, one of the major impetus power supply that lithium battery will be made to become automobile.Therefore, the quality and manufacturing technology of lithium battery It is required that being the most basic condition for meeting automobile difference operating condition and safety traffic.

However, the quality and manufacturing process of lithium battery slurry, are the basis of guarantee lithium battery quality, and in cell size Manufacturing process in, the cell size for having prepared to be processed is stirred, is a particularly important step process, with lithium electricity Pond application field it is increasingly extensive, the requirement to cell size manufacture craft also becomes higher and higher, in order to meet to quality Demand, a variety of different production equipments and its production technology are continued to optimize with continuous change, but in the system of cell size Make in technique, the stirring to slurry is still indispensable committed step, and the importance stirred is self-evident, therefore very much Producer is also constantly looking for new mixing plant and stirring means, such as

Chinese invention patent (publication No.: CN103285765A), discloses a kind of double planetary mixer, double-planet mixing Machine includes material cylinder container, power mixed structure and high speed dispersion structure, power mixed structure setting mixing main shaft, dispersion main shaft and Thermometric bar axis, power mixed structure also set up stirring motor, dispersion motor, rabbling mechanism and planetary mechanism, planetary mechanism connection On mixing main shaft, high speed dispersion structure setting scattering rod axis and emulsification bar axis, scattering rod axis and emulsification bar axis connection disperse master Axis, and power and control are provided by dispersion main shaft, the setting of material cylinder container is for cooling coil pipe and deflector.Double-planet mixing Machine is suitable for preparing using acetone substance as the lithium iron phosphate storage battery of solvent, is effective against the corrosivity of acetone substance.On The mixing plant efficient stable that the technical solution of patent disclosure provides is stated, realizes that recirculated water reduces waste, while can be avoided third Ketones solvent is abnormal at high temperature, is effective against the corrosivity of acetones solvent.But above-mentioned technical proposal provide stir Mixing equipment is unfavorable for the continuous and automatic operation of cell size homogenization system, and there is following problems:

2, the problem of sealing, since the equipment of above-mentioned technical proposal is after filler, and after stirring, there is no keep to slurry Easily there is operator's maloperation and metal tools etc. is mixed into slurry in the sealing of material, and friction is caused to form metallic, Lead to that being lost occurs in equipment or the risk of defective products occurs in slurry.

3, it splashes and the problem of dead angle, since the equipment of above-mentioned technical proposal is in slurry agitation, rabbling mechanism needs is stretched Enter into slurry, therefore, it is many that the diameter of rabbling mechanism needs to be less than material cylinder container, could facilitate disengaging material cylinder, this is resulted in The gap that necessarily will appear rabbling mechanism and material cylinder inner wall in whipping process is excessive, causes to be formed close to material cylinder inner wall surface side Dead material and powder mixing less than the case where, and the fineness of slurry is influenced, in addition, stirring since material cylinder upper end opening is arranged It also will appear the defect of slurry splashing in the process, while also will increase the risk of the slurry water suction denaturation after stirring.

4, the problem of high failure rate, since rabbling mechanism is above material cylinder, it may appear that slurry splashes to rabbling mechanism Inside, the failure rate for causing rabbling mechanism to damage are higher.

5, operation is discontinuous, difficult to realize to work continuously due to the limitation of the device structure of above-mentioned technical proposal, with And control the activity duration interval operation, therefore such equipment have the defects that be difficult on many production lines it is compatible；

In addition, will appear the case where material cylinder declines, Jin Erying in working long hours due to the limitation of prior art construction Ring mixing effect.
