Description
Technical field
The present invention relates to a kind of pulp of lithium ion battery mixed method, with and special-purpose mixing apparatus.
Background technology
The step of present pulp of lithium ion battery mixed method is as follows: in adding containers such as the powder of battery prescription and solvent, with mixer material is stirred; Adopt the method to mix pulp of lithium ion battery, the time of cost is generally more than 6 hours, and simple mechanical agitation is difficult to make nanometer to micron-sized particle fully to disperse, thereby mixed effect is not good enough.
The existing mixing apparatus that is used to mix pulp of lithium ion battery comprises container and mixer, adopts the mixing apparatus of this structure, the mixing speed that its band carries generally in 3000r/min, although improve mixing speed, simple mechanical agitation effect is still not good enough.
All the time, people think that ultrasonic wave has the effect that promotes the material refinement, thereby all select ultrasonic wave during corresponding mixing apparatus for use in development, as the Chinese patent communique on June 26th, 2002 the disclosed patent No. be ZL01255405.7, name is called the utility model patent that processor is sent out in the ultrasonic expansion of suspension direct-inserted, and the related product of this patent just is equipped with ultrasonic head; And in industrial production, because viscosity, the denseness of suspension or emulsion are often higher, and frequency of ultrasonic is higher, and the energy density of output is lower, be difficult to make material to produce effects such as cavitation, so that not good to the mixed effect of material, even if prolong incorporation time, also can't further improve the effect of mixing; For a long time, people thirst for having corresponding apparatus to mix pulp of lithium ion battery, to shorten the time of mixing, improve the quality of mixing.
Summary of the invention
The object of the present invention is to provide a kind of pulp of lithium ion battery mixed method; Another object of the present invention also is to overcome forefathers' prejudice, and a kind of special-purpose mixing apparatus that is applied to mix pulp of lithium ion battery is provided.
Pulp of lithium ion battery mixed method of the present invention, comprise in the adding containers such as the powder of battery prescription and solvent, with mixer material is stirred, emitting head with acoustic wave transducer when material is stirred immerses in the material, and material is applied the sound wave of 10KHz～18KHz through emitting head.
The special-purpose mixing apparatus that is applied to mix pulp of lithium ion battery of the present invention, comprise container and mixer, the acoustic wave transducer that is connected with sonic generator also is housed in container, and its emitting head can immerse in the interior material of container, and described container is double-deck water-cooling structure.
As the optimal technical scheme of special-purpose mixing apparatus of the present invention, described acoustic wave transducer is vised by the arm of force, and can move up and down along support; Described mixer is fixed in the support, and can move up and down.
Described container bottom end bearing has jack.
Pulp of lithium ion battery mixed method of the present invention is owing to apply the sound wave of 10KHz～18KHz in slurry, thereby has and shorten the time of mixing, and improves the beneficial effect of the quality of mixing; The special-purpose mixing apparatus that is applied to mix pulp of lithium ion battery of the present invention because acoustic wave transducer also is housed in container, thereby can make mixed slurries such as higher suspension of viscosity, denseness or emulsion produce effects such as cavitation, improves the quality of physical mixed.
