Vacuum stirring type ultrasonic wave dispersing breaking treatment tank

Abstract

The invention discloses a vacuum stirring type ultrasonic wave dispersing breaking treatment tank, which comprises a treatment tank body, wherein a stirring motor is arranged in the middle of the topend of the treatment tank body, both edges of the stirring motor are respectively provided with a material inlet and a vacuum pump, a sealing cover is movably arranged on the material inlet, the bottom portion of the treatment tank body is provided with a material outlet, and the treatment tank body is provided with a plurality of ultrasonic wave oscillators. According to the present invention, with the vacuum stirring type ultrasonic wave dispersing breaking treatment tank, the breaking and dispersing effect is good, the mixture of the carbon powder, the electric conduction agent and the binder can be completely electrolyzed, dispersed and broken in the vacuum stirring type ultrasonic wave dispersing breaking treatment tank, the electrode active particles and the electric conduction slurry can be mutually absorbed and dissolved, and the performance of the battery can be improved.

Description

Technical field [0001] The invention relates to the field of crushing equipment, in particular to a vacuum stirring type ultrasonic dispersion crushing treatment tank. Background technique [0002] Single vacuum stirring equipment and ultrasonic processing equipment are widely used in various fields. However, in new fields such as carbon nanotubes, composite materials, conductive pastes, conductive powders, special coatings, etc., as well as in new fields such as chemical, medical, drug extraction, dispersion, and crushing, the effect is not very satisfactory. This vacuum stirring ultrasonic processing equipment just combines two single equipments well to give the best processing effect. [0003] The traditional processing method is: carbon powder + conductive agent + adhesive are directly coated on aluminum foil or copper foil after high-speed stirring in a vacuum tank. However, there are often poorly dispersed fine particles after stirring in the vacuum tank, and the carbon pow...

AI Technical Summary

Problems solved by technology

However, after stirring in the vacuum tank, there are often poorly dispersed fine particles, and the carbon powder and the conductive agent cannot be fully fused; the separation and shedding of the electrode active material particles caused by the expansion and contraction of the carbon active material during charging and discharging affect the quality of the battery.
