The invention discloses a micro-nano
powder washing and separating device and method, and relates to the technical field of washing and separating of micro-nano
powder.The device comprises an outer
barrel, a centrifugal
barrel and a cover, a plurality of through holes I are formed in the
barrel wall of the centrifugal barrel, filter cloth is installed next to the inner wall of the centrifugal barrel, and a discharging opening is formed in the center of the bottom of the centrifugal barrel; the centrifugal barrel is connected with a driving motor I through a transmission
assembly, the driving motor I drives the centrifugal barrel to rotate, a liquid outlet is formed in the bottom of the outer barrel, the cover body is detachably connected with the outer barrel, a feeding
pipe and a high-pressure water / hot air
pipe are connected to the cover body, and a plurality of through holes II are formed in the high-pressure water / hot air
pipe; the cover body is provided with a stirring
paddle and a lifting
brush, the stirring
paddle is driven by a driving motor II, the driving
assembly drives the lifting
brush to move, and the problems that in the prior art, a common industrial centrifugal
machine is not suitable for washing micro-nano
powder, and the functions of repeated soaking and cleaning, automatic stirring and dispersing, automatic filter cloth cleaning and the like are difficult to achieve are solved; the washing efficiency is not high, and the powder purity is not ideal.
