The invention discloses a
paddle-free stirring
system and a
paddle-free stirring method for negative
electrode slurry, comprising a tank body, a heating jacket is provided on the outside of the tank body, a material blocking filter screen is provided in the tank body, a
slurry mixed with a water
solvent is provided below the material blocking filter screen inside the tank body, a
vacuum pump and a condenser are connected in series through a pipeline above the material blocking filter screen, and a material
discharge pipeline is provided at the upper end of the tank body. The
advantage of the invention is that the
vacuum pump is used to evacuate the tank body, and when the air pressure is reduced, the
boiling point of the
water body is also reduced accordingly. When the heating jacket is heated, the
water body in the
slurry boils to generate bubbles, and the
mechanical energy released by the generation, merging and
bursting process of a large number of bubbles generated by the violent boiling of the slurry is used to disperse the slurry, thereby completing the
paddle-free stirring of the negative
electrode slurry. Because the stirring is achieved by the bubbles generated by the boiling of the
water body, there is no high-speed shearing, which can prevent the stirring material from being damaged, and no additional heat will be generated due to shearing, so that the temperature of the stirring environment can be conveniently controlled.
