Sidewall on vertically offer several side outlets, each side outlet is all connected with a sieving equipment, described sieving equipment interior
Portion is sequentially installed with the screen cloth that sieve diameter tapers into from top to bottom.
Scheme, is provided with stop valve between described side outlet and sieving equipment further.
Scheme further, described discharging screen cloth is arcs of recesses, and the paddle on described agitator is in the ramp-like setting that dips down.
Scheme further, the sidewall of described conjunction slurry cylinder vertically offers three side outlets, each side outlet equally spacedly
Being all connected with a sieving equipment, the inside of described sieving equipment is provided with what sieve diameter tapered into the most equally spacedly
Upper strata screen cloth, middle level screen cloth, lower screen.
Scheme further, the aperture of described discharging screen cloth is the screen cloth passed through according to slurry qualified in sieving equipment
Aperture determines.
Closing, side outlet is set at differing heights on slurry cylinder sidewall, thus can the battery slurry of various location in involutory slurry cylinder
Deployment conditions and the viscosity of material are analyzed, with the quality of Primary Evaluation cell size.Respectively by cut-off at side outlet
Valve connects a sieving equipment, sieving equipment be internally provided with the screen cloth that multilamellar sieve aperture is different, and sieve aperture is more and more from top to bottom
Little, by the amount of the solid particulate matter that the different screen cloth of contrast is retained, solid particulate matter in slurry can be evaluated at same position
Particle diameter distribution situation, if there is larger particles, can be follow-up discharging screen cloth offer advisory opinion is provided.
The present invention uses airtight rewinding cylinder, it is to avoid cell size exposes in atmosphere.Rewinding cylinder middle and upper part is provided with slurry
The discharging screen cloth of material, mesh size is chosen according to the evaluation result of many layer multi-layers sieving equipment, and screen cloth is arcs of recesses.?
Discharging screen cloth is arranged above agitator, and its blade is downward-sloping setting, and coordinates the screen cloth of arcs of recesses, on the one hand can have
Imitate prevents solid particulate matter deposition obstruction screen cloth in slurry, and on the other hand slurry can produce centrifugal force in whipping process
Effect, and the screen cloth side passing the slurry through arcs of recesses enters into rewinding cylinder bottom portion.
Connect vacuum equipment being positioned at the rewinding cylinder below discharging screen cloth, on the one hand provide a kind of vacuum environment to slurry,
On the other hand in rewinding cylinder, negative pressure, beneficially slurry are formed faster by discharging screen cloth.
So solid particle impersonal language in the dispersibility of cell size and slurry is entered by the present invention by sieving equipment
Row is simple to be analyzed, and selects suitable discharging screen cloth according to analysis result, under the effect of agitator and vacuum equipment quickly
Discharging, whole sieve during slurry and air exclusion, be effectively guaranteed the quality of cell size.
