On be down sequentially installed with the screen cloth that sieve diameter tapers into.
Further scheme, stop valve is provided between the side outlet and excessively cribellum.
Further scheme, the discharging screen cloth be in arcs of recesses, and the paddle on the agitator is in the ramp-like setting that dips down.
Further scheme, described close vertically equally spacedly offer three side outlets, each side outlet in the side wall for starching cylinder
It is all connected with one and crosses cribellum, the inside for crossing cribellum is equally spacedly provided with the upper strata that sieve diameter tapers into from top to bottom
Screen cloth, middle level screen cloth, lower screen.
Further scheme, the aperture of the discharging screen cloth is according to the hole for crossing the screen cloth that slurry passed through qualified in cribellum
Footpath determines.
Side outlet is set at different height on slurry cylinder side wall is closed, so as to the battery slurry at diverse location in pairing slurry cylinder
The deployment conditions and viscosity of material are analyzed, with the quality of Primary Evaluation cell size.Pass through cut-off respectively at side outlet
Cribellum is crossed in valve connection one, and that crosses cribellum is internally provided with the different screen cloth of multilayer sieve aperture, and sieve aperture is less and less from top to bottom, is led to
The amount for contrasting the solid particulate matter that different screen clothes are retained is crossed, the particle diameter of solid particulate matter in slurry at same position can be evaluated
Distribution situation, if larger particles be present, advisory opinion can be provided for the selection of follow-up discharging screen cloth.
The present invention uses closed rewinding cylinder, avoids cell size exposure in atmosphere.Rewinding cylinder middle and upper part is provided with slurry
The discharging screen cloth of material, the evaluation result that mesh size crosses cribellum according to multilayer are chosen, and screen cloth is in arcs of recesses.Going out material screen
Online side is provided with agitator, and its blade is in tilt down setting, and coordinates the screen cloth of arcs of recesses, on the one hand can effectively be prevented
Only solid particulate matter deposition obstruction screen cloth, another aspect slurry can produce the effect of centrifugal force in whipping process in slurry,
And the screen cloth side for passing the slurry through arcs of recesses enters rewinding cylinder bottom portion.
Vacuum plant is connected in the rewinding cylinder below discharging screen cloth, on the one hand provides a kind of vacuum environment to slurry,
On the other hand negative pressure is formed in rewinding cylinder, is advantageous to slurry faster by the screen cloth that discharges.
So the present invention is entered by sieving equipment to solid particle impersonal language in the dispersiveness and slurry of cell size
The simple analysis of row, suitable discharging screen cloth is selected according to analysis result, it is quick in the presence of agitator and vacuum plant
Discharge, entirely slurry and air exclusion during sieving, be effectively guaranteed the quality of cell size.
