The invention relates to the technical field of silver
conductive paste preparation, in particular to a low-mobility and high-stability high-purity silver
conductive paste premixing device, and solves the problem that the quality of silver
conductive paste is finally reduced due to the fact that silver
powder cannot be uniformly wetted due to the fact that an isolation state of a wet material wrapped by
dry powder is formed due to an improper discharging mode. The discharging
assembly and the agglomeration eliminating
assembly are arranged on the kettle cover, the discharging
assembly is driven by
airflow to rotate and ascend and descend, silver
powder is annularly and evenly discharged and discharged in an accelerated mode, a conical plate of the agglomeration eliminating assembly is matched with an inner tangent ring and an outer tangent ring which rotate reversely, agglomerated materials are dispersed through a
cutting plate and a
cutting knife, and then the materials are thrown to the kettle wall through
centrifugal force to be further dispersed; the stirring rod and the
grinding rod of the stirring assembly are matched for full mixing, the
exhaust pipe is externally connected with the
vacuum pump to achieve vacuum defoaming, the overall structure avoids material agglomeration, silver
powder is evenly dispersed,
ion migration is restrained, and the
slurry premixing quality is improved.
