Description
Technical field
The invention belongs to battery pole piece detection field, is related to a kind of battery pole piece moisture content detection sampler, specifically
It is a kind of pole piece high vacuum, high temperature moisture content sampler.
Background technology
Preceding process material of the battery pole piece as battery production, the size of its moisture content directly affect battery quality, therefore,
The pole piece of production needs to carry out removing water process.The technique of the water removal to battery pole piece is at present, by the pole of 120 microns thickness
Piece is rolled into the pole volume between a diameter of 400mm-1200mm, and then pole volume is placed into drying oven and carries out vacuum and heating drying,
To remove the moisture that depolarization is rolled up.Rolled up in pole and carry out drying phase under vacuum, it is necessary to be detected to the interior moisture content of pole volume, but due to
Pole volume be integral type reel structure, thus be accordingly used in detection water content instrument probe can not extend into pole roll up in detected；Together
When, due to strict to pole volume local environment requirement, therefore pole can not be batched out and directly be contacted with air, otherwise can caused
All that has been achieved is spoiled for drying and dehydrating work.In addition, pole scroll is long-pending, quality is larger, pole can not be rolled up and carry out destruction sampling, in summary,
The detection for carrying out water content is rolled up to pole there is presently no good method, and then can not be known by whether dry pole volume meets to want
Ask.
The content of the invention
The technical problem to be solved in the present invention, it is to provide a kind of pole piece high vacuum, high temperature moisture content sampler, to realize not
Pole volume is destroyed, and ensures pole volume local environment and the moisture content of pole volume can be measured.
In order to solve the above technical problems, the technical solution used in the present invention is：
A kind of pole piece high vacuum, high temperature moisture content sampler, it includes：
For storing by the reel of dry pole piece, the reel is set with successively from the inside to the outside outside stores pole piece for fixation
Fixed bed, the placed layer for placing detected pole piece sample, for make pole piece sample have with inside stored pole piece
The heat conduction layer of identical thermal environment, and make pole piece sample that there is the shell of compression with equal tension inside stored pole piece.
As limitation of the invention：The reel is cylindrical shape made of corrugated paper；Fixed bed is high temperature resistant, vacuum-resistant
The first aerogel layer；The placed layer is the pole piece roll that forms of pole piece coiling identical with the pole piece of storage, on the pole piece roll
Offer the rectangular window for placing pole piece sample；The heat conduction layer is high temperature resistant, the second aerogel layer of vacuum-resistant；Institute
It is stainless steel sleeve to state shell of compression.
As limitation of the invention further：First aerogel layer is integrated cylindrical tube shape structure, the second airsetting
The cylindrical tube shape structure that the first aeroge semicircular cylinder and the second aeroge semicircular cylinder that glue-line matches for size are formed, described two
It is detachably connected between individual aeroge semicircular cylinder by the first bindiny mechanism.
As the restriction to the first bindiny mechanism in the present invention：First bindiny mechanism is included located at the first aeroge half
Projection on cylinder, and the groove to match on the second aeroge semicircular cylinder, with projection.
As the restriction to shell of compression in the present invention：The shell of compression be the first stainless steel semicircular cylinder for matching of size with
The cylindrical tube shape structure that second stainless steel semicircular cylinder is formed, can by the second bindiny mechanism between described two stainless steel semicircular cylinders
Dismantling connection.
As the further restriction to the second bindiny mechanism in the present invention：Second bindiny mechanism includes being respectively arranged on the
Engaging lug on one stainless steel semicircular cylinder and the second stainless steel semicircular cylinder stack shell, the engaging lug on the first stainless steel semicircular cylinder
It is connected with the engaging lug on the second stainless steel semicircular cylinder by bolt mechanism.
As a result of above-mentioned technical scheme, compared with prior art, acquired technological progress is the present invention：
（1）Pole piece sample and pole piece to be dried are co-located in same drying oven by the present invention, and by setting fixed bed, heat
Conducting shell, pole piece sample is arranged between fixed bed and heat conduction layer, the environment residing for simulated pole piece sample, and then makes pole piece
Sample is provided with shell of compression with by dry pole piece centre having same dry environment, make pole piece sample with it is to be dried
Pole piece centre there is same pressure, that is, ensure pole piece sample and same ring had by dry pole piece centre
Border condition, the data of pole piece sample are measured closer to by the data of dry pole piece roll with order；
（2）The fixed bed of the present invention uses aeroge with heat conduction layer, because the thermal conductivity of aeroge is pole piece thermal conductivity
1/10th, therefore when pole piece sample is between two layers aerogel layer, its moisture data after removing water is closer to being dried pole
Piece rolls up the data in centre, makes analysis result more accurate；
（3）The heat conduction layer of the present invention and shell of compression are demountable structure, therefore need to only be opened shell of compression and heat conduction layer
It can be taken off pole piece sample and carry out water content detection, without the drying oven of vacuum high-temperature entirely will be taken out with regard to energy by dry pole piece
The detection to pole piece moisture is enough realized, i.e., whether the pole piece that can determine whether to be dried in the drying process reaches requirement, avoid taking
Go out pole piece measure dry it is unqualified after melt down time for toasting again again and waste and the wasting of resources.
In summary, the present invention is simple in construction, without dry pole piece roll is taken out, i.e., can provide more accurate pole
Piece dries data.
The present invention is applied to drying for current all pole pieces and detected.
The present invention is described in further detail below in conjunction with specific embodiment.
