Description
Technical field
The invention belongs to powder sampling technique fields, are related to sampler more particularly to a kind of powder automation sample train
System and its application method.
Background technique
As one of new chemical materials, the product for being fluorinated work has high-performance, high added value, and fluorine chemical industry is referred to as Huang
Golden industry.Fluorine contained chemicals mainly have inorganic fluoriding work, fluorine carbon chemicals, fluoropolymer (PTFE, PFA) and fluorine-containing fining
Product.
Fluorine chemical industry can be divided to inorganic fluorine chemical industry and the big industry of Organic fluoride chemical industry two again.
In inorganic fluorine chemical industry, although the year-on-year range of decrease of traditional product is obvious, high-end product especially lithium hexafluoro phosphate
Demand growth maintain vigorous pace.New energy class product lithium hexafluoro phosphate etc. welcomes with the development of new energy field to be continued
The situation of outburst.Lithium hexafluoro phosphate (LiPF6) is the most important component part of electrolyte composition, accounts for electrolyte totle drilling cost
43%.Packing instructions according to the 8th article in HG/T 4066-2015 " packaging, transport and storage " to lithium hexafluoro phosphate, net content
The lithium hexafluoro phosphate product of≤25kg, the stainless steel barrel for meeting the requirement of GB150.1~150.4 must be used to pack, and (industry is usual
Referred to as lithium salts bucket).
Important raw material of the lithium hexafluoro phosphate as field of lithium ion battery, purity by HG/T 4066-2015 requirement not
Lower than 99.95%, moisture is not higher than 0.0020%.Lithium hexafluoro phosphate be hygroscopicity it is strong, it is soluble easily in water, meet water meet air separation,
Decompose the powder or crystalline solid for generating irritation toxic gas.Its appearance is white crystals or powder, relative density 1.50.Six
Lithium fluophosphate is decomposed rapidly due to the effect of vapor in air, is released PF5 and is generated white smoke.
Therefore, whether the sample detection in production process or finished product entry and exit factory sample detection be all for lithium hexafluoro phosphate
The controllable state thoroughly completely cut off must be in air.In this way, both can guarantee that lithium hexafluoro phosphate material or finished product avoided in air
The pollution of the impurity such as moisture, and can guarantee the personal safety of operator, and the working efficiency of sample detection is continuously improved.
Currently, the prior art of lithium hexafluoro phosphate finished product (lithium salts bucket) sampling for stainless steel packaging, sees below.

Application number: CN201721460469.9, the applying date: 2017-11-03, applicant: Henan Hua Rui new high-tech material Co., Ltd),
In disclose " one valve bag of valve bag system is sleeved on the dual valve bag inside another valve bag ", have the disadvantage in that
Argon pressure is not shown in valve bag, it is difficult to control, and there is leakage hidden danger between valve bag and long air pipe, short tube, this takes
Sampling device is to be only available for the sampling work of lithium salts bucket with simple tool, manual operation in sampling.
(2) CN205580786U, lithium hexafluoro phosphate sampler (publication date: 2016-09-14, application number:
CN201620284744.5, the applying date: 2016-04-07, applicant: Dongguan City Tian Feng power material Co., Ltd), wherein public
It has opened technical characteristic " inert gas shielding box ", but undisclosed specific structure feature, and specific displaced air, control
The method of protective gas pressure, protective gas pressure are unable to accurately control and adjust, and can only operate by rule of thumb, which exists
It is also to be only available for the sampling work of lithium salts bucket with simple tool, manual operation when sampling.
Sampling facility in above two patents is simple tool, the pure manual operations of operation mode system.From stringent meaning
Justice says that whether valve bag or inert gas shielding box displaced air are thoroughly depending on the experience and sense of responsibility of operator.And
This kind of sampler is only applicable to disposably take out general example weight in a lithium salts bucket, does chemical examination detection.
In addition, prior art CN103512779B, a kind of sampler and its sampler barrel (publication date: 2016-01-13, application
Number: CN201310299988.1, the applying date: 2013-07-17, applicant: Duo-fluoride Chemicals Co., Ltd., Hao Ran), this
It is for a device of lithium hexafluoro phosphate production line pipeline and the sampling of lithium salts bucket, sampling mechanism is two or so pistons, in
Between have connecting rod, formed in channel with this sampling chamber；Material channel should be filled with inert gas insured's gas, vacuumize again,
It needs separately to increase vacuum generator or vacuum pump；During entire Job Operations, left and right piston is multiple by manpower driving, spring
Position；Sampler still operates by hand entirely, is difficult to realize the accurate sampling of the different frequencys, Perfect Time interval.
To sum up, the above-mentioned prior art is all the device and sampling instrument based on manual operation, rather than sampling equipment；All
It is unable to the pressure parameter of strict control isolation air, experience can only be leaned on to control the degree of displaced air；It is not able to satisfy just yet
Normal production pipeline clinical practice, the technique requirement accurately sampled.
