Sedimentation is characterization one of slurry character, when slurry settles in a short time, is easy to cause mistake in coating process
The blocking of screen net, pulp flow is unsmooth, and the fluctuation of pole piece surface density is larger.The mode for producing common testing size sedimentation at present is to take
The slurry of certain volume stands a period of time rear-inclined graduated cylinder, pours out the slurry at three positions in upper, middle and lower, survey it in graduated cylinder
Solid content judges whether slurry settles with this.This method is easy to operate, but slurry inclines with graduated cylinder in toppling process
Tiltedly, it is easy and lower slurry mixes；Secondly, the accurate location of the slurry at each position is taken to be not easily controlled, lead to test result
There is a certain error.
Utility model content
In consideration of it, the utility model provide it is a kind of can simple, the sedimentation of Accurate Determining slurry pulp of lithium ion battery
Settle test device.
The utility model provides a kind of pulp of lithium ion battery sedimentation test device comprising staving, one end of staving
Be connected with bung, the opposite other end has pedestal, be provided with multiple through-holes on the side wall of staving, multiple through-holes are along staving
It is axial equidistantly to arrange, port lid is installed on through-hole, port lid is articulated on the side wall of staving.
Further, above-mentioned staving is drum.
Further, above-mentioned through-hole is rectangular opening or circular hole.
Further, above-mentioned through-hole connects tapping channel, and tapping channel is fixedly installed on the side wall of staving.
Further, above-mentioned tapping channel is obliquely extended from bung to pedestal.
Further, above-mentioned tapping channel is groove body.
Further, sealing ring is provided in above-mentioned port lid.
Further, above-mentioned bung is rotary seal cap.
Further, above-mentioned pedestal is sloped footing.
A kind of pulp of lithium ion battery provided by the utility model settles test device, main compared to the prior art
It has the advantage that through the through-hole equidistantly arranged axial on setting staving and staving, is packed into after slurry in staving, edge
It is axial open port lid from top to bottom, slurry successively flows out or the slurry of different location, thus can pass through simple structure
Achieve the purpose that relatively simple, Accurate Determining slurry sedimentation.
