Shape structure.
As shown from the above technical solution, battery battery core is placed on the electrolyte extraction of a full nitrogen by this utility model
In storehouse, organic solvent is used to carry out dissolving the electrolyte within eluting battery core, it is possible to be extracted completely by the electrolyte in battery core
Coming, in the process, there is not any chemical change and extraneous contamination, the beneficially analysis of dead battery electrolyte in electrolyte
Measure；This device is simple to manufacture, easy to clean, easily operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
A kind of disabled lithium ion cell electrolyte extraction element as shown in Figure 1, extracts storehouse 1 including electrolyte, to electrolysis
Liquid extracts storehouse 1 and is filled with the nitrogen pot 2 of nitrogen, extracts vacuum pump 3 and the electrolyte receiving flask 4 of storehouse 1 evacuation to electrolyte, electricity
The inside solving liquid extraction storehouse 1 is provided with ultrasonic elution pool 5, and the Chi Kou of ultrasonic elution pool 5 is arranged over solvent in communication and injects
Pipe 6, the bottom of ultrasonic elution pool 5 is provided with the discharging tube 7 connected with electrolyte receiving flask 4, and electrolyte extracts and is additionally provided with storehouse on storehouse 1
Door 8 and Pressure gauge 9, nitrogen pot 2, vacuum pump 3 and electrolyte receiving flask 4 are arranged at electrolyte and extract the outside in storehouse 1.Specifically
Saying, i.e. electrolyte extracts storehouse 1 is an airtight warehouse, is the main body of whole device, is by the extraction of battery battery core electrolyte
Device；Door 8 is used for entering to put in ultrasonic elution pool 5 by electricity people's core, and the top of ultrasonic elution pool 5 is mounted in electrolyte and carries
Take the solvent ascending pipe on storehouse, be connected with electrolyte receiving flask 5 by discharging tube 7 bottom ultrasonic elution pool 4.
Further, nitrogen pot 2 and vacuum pump 3 are connected with electrolyte extraction storehouse 1 by three-way switch valve 10.I.e. electrolyte
Extract and be mounted with that three-way switch valve 10, one end of three-way switch valve 10 are connected on nitrogen pot 2 on the side casing in storehouse 1, another
End is connected on vacuum pump 3.Control three-way switch valve 10 by the numerical value of the Pressure gauge 9 on observation electrolyte extraction storehouse 1 to cut
Change, carry out evacuation and inflated with nitrogen.
Further, discharging tube 7 is provided with discharge opeing ball valve 71, and solvent ascending pipe 6 is provided with fluid injection ball valve 61.
Further, the entrance 62 of solvent ascending pipe 6 be positioned at electrolyte extract the outside in storehouse 1 and this entrance be opening big,
