Production cost.
Detailed description of the invention
Fig. 1 is a kind of principle schematic diagram of the safe forcible entry device of waste lithium cell of the present invention.
Specific embodiment
Invention is further described in detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, the safe forcible entry device of a kind of waste lithium cell, including store lye 1 crack storehouse 2,
The alkali liquid high-level groove 3 and circulatory pool 4 for storing lye 1 are cracking the waterproof forcible entry for being placed with and being immersed in lye 2 in storehouse 2
Machine 5 is provided with feed inlet 21, fluid infusion 22 and overflow port 23, the fluid infusion 22 for cracking storehouse 2 on the bulkhead for cracking storehouse 2
It is connected by regulating valve 6 with the liquid outlet 31 of alkali liquid high-level groove 3, is provided in cracking storehouse 2 and cracks storehouse 2 to real-time monitoring
The PH meter 7 of interior lye pH value, the overflow port 23 for cracking storehouse 2 is connected with the import 41 of circulatory pool 4；In the present embodiment,
It further include fluid infusion controller 8, fluid infusion controller 8 is counted 7 signals with regulating valve 6 and PH simultaneously and connect, and it is broken that the PH counts 7 real-time monitorings
Solve storehouse 2 in lye pH value and by the pH value Real-time Feedback monitored to fluid infusion controller 8,8 real-time reception PH of fluid infusion controller
PH value real time detection signal that meter 7 is sent and according to the reflection of pH value real time detection signal to crack the real-time pH value of storehouse lye automatic
The aperture for controlling to adjust valve 6, enables the lye in alkali liquid high-level groove 3 to be replenished in time into storehouse 2 is cracked, makes to crack lye in storehouse 2
Concentration is automatically held in preset concentration, and the automatization level of equipment can be improved in this way, improves production efficiency, improves the fortune of equipment
Row stability and safety in utilization；In the present embodiment, circulation fluid import 24 and circulation fluid are provided on the bulkhead for cracking storehouse 2
Outlet 25, the circulation fluid outlet for cracking storehouse 2 25 are connected with the import of circulating pump 9, and circulating pump 9 exports and cracks following for storehouse 2
Ring liquid import 24 is connected, and recycles lye in cracking storehouse 2 by circulating pump 9, plays stirring action, so as to crack in storehouse 2
The electrolyte that lye flows out after capable of dismantling with lithium battery sufficiently reacts, and improves electrolyte recovering effect；In the present embodiment, exist
It cracks and is provided at the feed inlet 21 in storehouse 2 waste lithium cell to be delivered to the conveying dress cracked in 2 inner waterproofing destroying machine 5 of storehouse
Set 10；In the present embodiment, it is provided in circulatory pool 4 solution recycled in circulatory pool 4 is delivered to electrolyte recycling
The submerged pump 11 of workshop section, more convenient operation；
Working principle of the present invention is as follows:
The present invention is based on following lithium battery electrolytes reflection processes to be designed, and lithium battery electrolytes are lithium hexafluoro phosphate, the change
It closes object and lye moment carries out following decomposition reaction:
LiPF6+8NaOH----LiF+5NaF+Na3PO4+4H2O
Above-mentioned reaction equation can be seen that lithium hexafluoro phosphate and not generate all extremely strong hydrogen fluoride of toxicity and corrosivity under alkaline condition
Gas or hydrofluoric acid.
In use, being first configured with certain density sodium hydroxide solution in alkali liquid high-level groove 3, then pass through regulating valve 6
Lye is cracked into storehouse 2 from the injection of fluid infusion 22, until the lye cracked in storehouse 2 rises to 23 position of overflow port, cracks storehouse 2 at this time
Interior waterproof destroying machine 5 can be immersed in lye；Then waste lithium cell is sent into from feed inlet 21 by conveying device 10 broken
It is dismantled in waterproof destroying machine 5 in solution storehouse 2, waterproof destroying machine 5 completes the forcible entry to waste lithium cell in lye, it is ensured that
Waste lithium cell electrolyte during forcible entry will not be contacted with air, after waste lithium cell forcible entry the electrolyte that flows out can with it is broken
Lye in solution storehouse 2 sufficiently reacts, so that it is guaranteed that lithium battery electrolyte during forcible entry will not contact decomposition release with air
Toxic gas pollutes environment out；During waterproof destroying machine 5 dismantles waste lithium cell, circulating pump 9 makes lye broken
Solution recycles in storehouse 2, plays stirring action, enables to crack lye in storehouse 2 and sufficiently reacts with the electrolyte flowed out after lithium battery forcible entry；
Meanwhile 7 meeting real-time monitoring of PH meter cracks the pH value of lye in storehouse 2 and gives the pH value Real-time Feedback monitored to fluid infusion controller
8,8 real-time reception PH of fluid infusion controller count the pH value real time detection signal that 7 send and according to the reflections of pH value real time detection signal
The aperture for cracking the real-time pH value automatic control and adjustment valve 6 of storehouse lye enables the lye 1 in alkali liquid high-level groove 3 to be replenished in time into broken
Storehouse 2 is solved, the concentration for cracking lye in storehouse 2 is made to be automatically held in preset concentration；It is added with the continuous of lye in storehouse 2 is cracked, when
When cracking solution level in storehouse 2 and being higher than overflow port 23, cracks the solution in storehouse 2 and can be discharged by overflow port 23 from import 41 and followed
Cisterna ambiens 4, the solution (decomposition product and organic solvent comprising lithium battery electrolytes) collected in circulatory pool 4 is again by submerged pump 11
It send to electrolyte recycle section.
The invention has the advantages that completing the forcible entry to waste lithium cell in lye, it is ensured that lithium battery is during forcible entry
Electrolyte will not contact decomposition with air and release toxic gas pollution environment, and lithium battery forcible entry process no longer generates corrosion
Property extremely strong hydrofluoric acid, it is ensured that during the forcible entry of waste lithium cell can safety and environmental protection treatment of battery solution, not only mention significantly
High safety, and reduce to equipment and workshop construction requirements, reduce enterprise's production cost.
