Abstract
The utility model discloses a kind of device for pulp of lithium ion battery granularity Detection, it is characterized in that: material selection stainless steel, and shape is rectangular parallelepiped, and length is 170mm, and width is 64mm, is highly 13mm.With a skewed slot above, length is 140mm, and width is 12mm, and both sides are provided with the scale value of different depth, and change in depth is peak to peak (zero) from top to bottom.The utility model has the advantages that the size-grade distribution for powder body material in rough measure pulp of lithium ion battery and degree of scatter, be convenient to select suitable screen cloth specification, effectively improve slurry and to sieve effect, improve the consistance of coating pole piece.
Description
Technical field
The utility model relates to field of lithium ion battery, particularly relates to a kind of device for pulp of lithium ion battery granularity Detection.
Background technology
Batching can be described as the operation played a decisive role in lithium ion battery production run, if slurry agitation is uneven, degree of scatter is bad, then can cause adverse influence to later stage each procedure.Even if slurry agitation is even, in slurry, residual a small amount of bulky grain is also kept away and can not be exempted from, therefore operating personnel is needed to carry out process of sieving after discharging, a small amount of bulky grain in elimination slurry, improve the homogeneity of slurry, effectively improve the consistance of coating pole piece, but technician cannot select suitable screen cloth, cause the loaded down with trivial details of program, work is complicated.
Summary of the invention
The purpose of this utility model is to provide a kind of a kind of device for pulp of lithium ion battery granularity Detection being convenient to select suitable screen cloth.
For achieving the above object, the technical solution adopted in the utility model is:
For a device for pulp of lithium ion battery granularity Detection, comprise rectangular parallelepiped, it is characterized in that: with skewed slot in the middle of above rectangular parallelepiped, with scale mark on the rectangular parallelepiped of the both sides of skewed slot.
Described skewed slot both sides scale value scope is 0 ~ 150 μm, and minimum division value is 5 μm.Skewed slot change in depth is from top maximal value to below minimum value, and minimum value is 0.
Select the screen cloth of appropriate size to seem most important, not only can save the working time but also the homogeneity of slurry can be improved.Before slurry sieves, do rough measurement in advance to the size-grade distribution situation of slurry, such operating personnel just tentatively can grasp the degree of scatter of slurry, is convenient to select suitable screen cloth.
Accompanying drawing explanation
Fig. 1 is vertical view of the present utility model.
Fig. 2 is stereographic map of the present utility model.
In accompanying drawing: 1, skewed slot; 2, scale mark; 3, rectangular parallelepiped.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The utility model as shown in Figure 1 and Figure 2,
For a device for pulp of lithium ion battery granularity Detection, comprise rectangular parallelepiped 3, it is characterized in that: with skewed slot 1 in the middle of above rectangular parallelepiped, with scale mark 2 on the rectangular parallelepiped 3 of the both sides of skewed slot 1.
Described skewed slot 1 both sides scale value scope is 0 ~ 150 μm, and minimum division value is 5 μm.Skewed slot 1 change in depth is from top maximal value to below minimum value, and minimum value is 0.
Use step 1, fully stirred evenly by the sample meeting product standard viscosity, dip several samples with glass bar, the most position, deep (the maximum position of scale value) of instillation skewed slot, infusion volume to be slightly unnecessaryly advisable can be full of skewed slot.
2, with held by both hands scraper, be horizontally placed on the maximum position of scale value (in sample edge) and make scraper and blade surface perpendicular contact.Within 3 seconds, scraper is pulled through to minimum scale position by maximum scale position.
3, immediately (must not more than 5 seconds) makes sight line become 15 ° ~ 30 ° angles with skewed slot plane, observes in skewed slot light
Uniform particles appears place, and writes down corresponding scale value.This scale value is the fineness of institute's test specimens.
Slurry granularity detection device is a stainless steel flat plate having dual-cavity on surface, and the degree of depth of groove is changed to the null value of the other end by the maximal value of one end.Place sample, in groove, spread to sample film with scraper, the lines produced from film are to measure the size of sample particle.Flat board marks out the corresponding degree of depth of groove, to read the size of measured particle.
Because the particle size distribution of tested dusty material is different, be in certain scope, therefore will set skewed slot, the degree of depth is changed to minimum value 0 by maximal value from top to bottom, so adopt skewed slot.
Embodiment recited above is only be described preferred implementation of the present utility model; not design of the present utility model and protection domain are limited; under the prerequisite not departing from the utility model design concept; the various modification that in this area, common engineering technical personnel make the technical solution of the utility model and improvement, all should fall into protection domain of the present utility model.
