Abstract
The utility model discloses a battery anode powder material tap density testing device, comprising a measuring cylinder provided with a base seat. The base seat is provided with damping components and a top cover matched with the measuring cylinder is disposed on the top of the measuring cylinder. The battery anode powder material tap density testing device guarantees small measuring result error and is reasonable in structure. The battery anode powder material tap density testing device employs organic glass and thus facilitates observation, enables the measuring cylinder to be fixed easily with the base seat, improves safety performance of the measuring cylinder during compacting with the damping components disposed on the base seat of the measuring cylinder, and, with the top cover disposed on the top of the measuring cylinder, solves the problem of increase of error caused by splashing of powder material during conventional battery powder material tests. The battery anode powder material tap density testing device guarantees accuracy and effectiveness of the tap intensity of the powder material, is convenient for measuring, is safe and saves cost.
Description
Technical field
The utility model relates to a kind of determinator of chemical substance, is specifically related to a kind of determinator of battery positive pole powder material tap density.
Background technology
All need carry out the test of tap density in a lot of fields to powder.For example: the tap density of active substance is the important parameter that influences the lithium ion battery performance, in supplied materials detection and finished product detection, all wants detection of active material tap density usually.At present the tap density of powder body material generally all is that adopt that the tap density appearance provides a kind of do not have base and uncovered glass cylinder is measured, and this method can cause that graduated cylinder is not easy to fix, frangible, shortcoming such as powder overflows easily, measuring result error is big.
Summary of the invention
To the deficiency that prior art exists, the utility model technical matters to be solved is, provide a kind of simple and reasonable for structure effectively, handling safety, the measurement result determinator of battery positive pole powder material tap density accurately.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of determinator of battery positive pole powder material tap density; Comprise that one has the graduated cylinder of base, said base is provided with damping part, is provided with the top cover that matches with it at the graduated cylinder top.
The determinator of above-mentioned battery positive pole powder material tap density, said damping part are the rubber sleeve that is set on the base.
The determinator of above-mentioned battery positive pole powder material tap density, said rubber sleeve comprise end cover and overlap vertical graduated cylinder protection portion the end of with.
The determinator of above-mentioned battery positive pole powder material tap density, cover of the said end is wholely set with graduated cylinder protection portion.
The determinator of above-mentioned battery positive pole powder material tap density, said graduated cylinder top is provided with external thread, and top cover screws with said graduated cylinder screw thread through the internal thread that is provided with in it and is connected.
The advantage of the determinator of the utility model battery positive pole powder material tap density is: little, the rational in infrastructure employing organic glass of measuring result error material, be convenient to observe; Base is set, and the graduated cylinder easy fixation through on the graduated cylinder base, damping part being set, has been strengthened graduated cylinder in jolt ramming process safe performance; The top cover that is provided with at the graduated cylinder top, powder spilt the problem that causes error to increase during battery powder materials was tested before having solved, and had increased base, the graduated cylinder easy fixation.Use this device to test battery powder, revised the error that the powder in the past powder tapping mensuration process overflows, solved graduated cylinder and be not easy fixation problem; Use the tap density of the powder body material that this device obtains; Accurate and effective, measure easy, thereby instrument safety is practiced thrift cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details;
As shown in Figure 1, a kind of determinator of battery positive pole powder material tap density comprises that one has the graduated cylinder 1 of base 2; For ease of observing; This graduated cylinder 1 selects for use the organic glass transparent material to process, and damping part 3 is set on base 2, and damping part 3 is for being set in the rubber sleeve on the base 2.Rubber sleeve comprises end cover 31 and overlaps 31 vertical graduated cylinder protection portions 32 end of with.End cover 31 is wholely set with graduated cylinder protection portion 32.Be provided with the top cover 4 that matches with it at the top of graduated cylinder 1.The top of graduated cylinder 1 is provided with external thread 5, and top cover 4 screws with the external thread 5 of this graduated cylinder 1 through the internal thread 6 that is provided with in it and is connected.
The concrete operations of measuring may further comprise the steps:
1, institute to be recorded sample drying, accurately weigh with balance.
2, the battery powder of accurate weighing is packed in the organic glass graduated cylinder of establishing, put base sheath, then the graduated cylinder lid is tightened, graduated cylinder is placed on the jolt ramming instrument, the vibration graduated cylinder no longer reduces until volume of sample.
3, take off graduated cylinder then, read the volume number that the surface reaches after the jolt ramming, calculate tap density.
The formula that calculates tap density is: ρ
Jolt ramming=2m/ (V
High+ V
Low)
Wherein, ρ
Jolt rammingBe the tap density of calculating, m is an example weight, V
HighBe the bulking value of higher level after the sample jolt ramming, V
LowFor after the sample jolt ramming than the bulking value of low degree.
4, sample is taken out from graduated cylinder, clean graduated cylinder.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection domain of the utility model.
