For known technology, therefore it is not described in detail herein.
During the chemical conversion of battery negative pressure, open the control valve 27 controlling module, make the second Pneumatic valve 24 connect with positive pressure source B, from
And the second Pneumatic valve 24 is opened and connects with vacuum source C and carries out evacuation so that suction nozzle 12 is close to the fluid injection of electrokinetic cell A
Hole, produced gas and the electrolyte of spilling during draw power battery A chemical conversion, described electrolyte major part is stored in described storage
In liquid cup 13, gas and the most least a portion of electrolyte enter in corrosion-resistant flexible hose 4, during evacuation, and described digital display pressure
The extracting vacuum value that carries out table 20 reads in real time and carries out control signal transmission, it is achieved automatically control, thus vacuum pumping rate is fast, and
Maximum pressure value can be adjusted controlling by fine vacuum pressure regulator valve 25, thus evacuation is controlled, and reliability is high；Described gas-liquid is divided
Described gas and electrolyte, described electrolyte and trickle impurity warp it is sufficiently separated from the gas liquid separating filtering portion of filter 31
Enter liquid collecting cup 32 after filtration, be then discharged through liquid collecting cup 32, thus discharge opeing is convenient；Described gas is still stored in corrosion-resistant
In flexible hose 4, now, drying section effect, by the gas in pipeline and because the dampness that electrolyte brings is dried, warp
Dried gas is evacuated extraction, thus, control module 2 after entrance is only dried gas, from without to control
Module 2 causes corrosion, so, not only substantially prolongs the service life controlling module 2, and ensure that the gas controlling module 2
Close property；After completing after negative pressure is melted into, relief valve 28 is opened, and makes vacuum filter 29 connect with air, then toward corrosion resistance
Input positive pressure air in flexible hose 4, the electrolyte in liquid storing cup 13 can be injected in electrokinetic cell A liquid injection hole again, thus
The performance of electrokinetic cell A can be improved, and keep stability and the concordance of electrokinetic cell A performance；When the whole vacuum of electrokinetic cell A
When system pressure is Jun Heng with external atmospheric pressure, suction nozzle 12 and electrokinetic cell A prepare to depart from, and because relief valve 28 is connected to very
Air filter 29, such that it is able to avoid pressure release when, takes to flexible spout module 1 and electrokinetic cell A unnecessary
Impurity；Now, close relief valve 28, and make the second Pneumatic valve 24 by disconnecting control valve 27 and the connection of the second Pneumatic valve 24
Guan Bi, thus block the connection of fine vacuum pressure regulator valve 25 and vacuum source C, then open control valve 27 and the company of the first Pneumatic valve 22
Connecing, make the first Pneumatic valve 22 open, so that coarse vacuum pressure regulator valve 21 turns on vacuum source C, the pressure of coarse vacuum is by low very
Air-conditioning pressure valve 21 controls to adjust, and then by the soft road of corrosion-resistant flexibility 4, makes the suction nozzle 12 in flexible spout module 1 produce slightly
Negative-pressure gas, described slight negative-pressure gas makes the electrolyte not returned in electrokinetic cell A remained a little all be recovered to
In gas-liquid separation filter 31, in case entrained electrolyte drippage electrokinetic cell A during suction nozzle 12 departs from electrokinetic cell A
On, pollute electrokinetic cell A.After electrokinetic cell A completely disengages from, closing control valve 27, make whole vacuum system close.Chemical conversion next time
Repeat above-mentioned action.
In the present embodiment, the quantity of electrokinetic cell A can be extended in the way of using serial or parallel connection, the most disposably process
Electrokinetic cell A quantity can be arranged as required to.
During orientation, above-mentioned left and right describes, with flexible spout module 1 place in scheming as a left side, controlling module 2 place be the right side.
