To be designed for the circular cover of cylindrical battery.
As shown in Figure 1, the utility model provides a kind of battery cover board 1, note round 2 and note are provided on battery cover board 1
Round sealing 20.It is different from the staged note round on existing battery cover board to infuse round 2.It for example can be common for infusing round 2
Through-hole, the Interface Matching that can be sized to maintenance generating apparatus again of round is infused, so that the telescopic rod in interface can
Change liquid operation to protrude into note round.
As shown in Figures 2 and 3, the back side of battery cover board 1 is arranged in around note round 2 for note round sealing structure 20.Specifically
Ground, note round sealing structure 20 includes: tubular slideway 21, elastic component 23 and sealing element 22.Tubular slideway 21 is around note round 2
It is formed in the back side of battery cover board 1 and extends towards inside battery, be formed at least one through-hole on the peripheral wall of tubular slideway 21
210.The bottom of elastic component 23 is fixed relative to tubular slideway 21 and is set to tubular along the compression of the axis direction of tubular slideway 21
In slideway 21.Sealing element 22, which is set to, abuts with the top of elastic component 23 and seals note round 2 in tubular slideway 21.Sealing element 22
Opening note round 2 can be moved down along tubular slideway 21 under external force, and move up closing note after external force removal
Round 2.
As Figure 4-Figure 6, in use, safeguarding that the telescopic rod 11 in the interface 10 of generating apparatus again can be extended downwardly and be compressed
Sealing element 22 makes to infuse the opening of round 2, and gap S of the electrolyte between interface 10 and telescopic rod 11 flows out, and along telescopic rod 11
It flows downward and passes sequentially through the inside that the through-hole 20 on note round 2 and tubular slideway 21 flows into battery.It changes after the completion of liquid, stretches
Contracting bar 11 moves upwards retraction, and sealing element 22 rebounds under the action of elastic component 23, reseals note round 2.
For the ease of processing, tubular slideway 21 is coaxial with note round 2 and is integrally formed on battery cover board 1.Tubular slideway
Battery cover board between 21 and note round 2 is formed as the limiting section of sealing element 22.Specifically, the diameter for infusing round 2 is less than tubular
The diameter of slideway 21, so that the circumferentia for the battery cover board being located between note round 2 and tubular slideway 21 can be used as sealing element
The limiting section at 22 tops.In this way, when external force removal rear seal 22 can be close to circumferentia to seal note round 2.
In order to which elastic component 23 to be stably placed to the inside of tubular slideway 21, tubular slideway 21 protrudes into the one of inside battery
End is provided with end plug 24.Preferably, end plug 24 is discoid boss, the side that discoid boss is connected through a screw thread or welds
Formula is set to the bottom of tubular slideway 21.Specifically, elastic component 23 is ring-spring, and the bottom of ring-spring can be covered in boss
On.
Electrolyte can flow uniformly to the inside of battery when in order to guarantee to change liquid, and through-hole 210 is set as multiple and along cylinder
The side wall of shape slideway 21 is circumferentially uniformly distributed.
In order to according to the amount of replacement electrolyte number and change the opening degree of through-hole, through-hole 210 is set as edge
The axially extending strip-shaped hole of tubular slideway 21.In this way, when the electrolyte of injection is fewer, in maintenance regeneration equipment interface
Telescopic rod can downward compressive seal 22 by a small margin, make 210 opening sub-fractions of through-hole；And when the electrolyte ratio of injection
When more, telescopic rod in maintenance regeneration equipment interface can significantly downward compressive seal 22, beat through-hole 210 all
It opens.
Further, sealing element 22 is the compound gasket adaptable with the cross sectional shape of tubular slideway 21.Compound gasket packet
It includes and is interconnected with one another and towards the first gasket of note round 2 and towards the second gasket of elastic component 23.First gasket is by resistance to electricity
The elastic material of solution liquid is made, and the second gasket is made of aluminum.In this way, compound gasket can not only prevent the etch of electrolyte but also can be with
Scheduled shape is kept, there is preferable service life.
As shown in fig. 7, the first note round and the second note round are provided on battery cover board, for example, the first note round is used for
Fluid injection is carried out to battery, changes liquid or fluid infusion, the second note round is for vacuumizing battery；Alternatively, for example, the first note round
For vacuumizing to battery, the second note round is used to carry out fluid injection to battery, changes liquid or fluid infusion.In this way, working as one of them
Note round is for when vacuumizing along flow pass Y, another note round to can be used for along flow channel X fluid injection.Therefore, by setting
Setting two note rounds can reduce the pressure difference that battery case is subject to, and then reduces and change liquid damage caused by battery, and liquid is changed in promotion
Efficiency.
The utility model additionally provides a kind of lithium slurry battery, which includes battery case and battery case
It fits together to form the battery cover board of closed chamber and be arranged in the intracorporal battery core of battery case.Battery core includes multiple alternating layers
Positive plate/diaphragm/negative electrode tab of folded setting, battery cover board are above-mentioned battery cover board.When needing to tie up to lithium slurry battery
When shield regeneration, do not need will to carry out changing in battery transfer to glove box or drying room liquid operation, it only need to be by adapter and external
The note round of battery is connect by pipeline with external liquid system of changing, to complete on-line maintenance regeneration.
Although the present utility model has been described by reference to the preferred embodiments, but in the model for not departing from the utility model
In the case where enclosing, various improvement can be carried out to it and can replace component therein with equivalent.Especially, as long as not depositing
