Detailed Description
Referring to fig. 1, the utility model discloses a lithium battery electrolyte recovery device, which comprises a liquid storage tank high tank 1, a liquid storage tank low tank 2 and a liquid injection barrel 3; wherein the horizontal height of the liquid storage tank low tank 2 is below the liquid storage tank high tank 1, and the horizontal height of the liquid injection barrel 3 is below the liquid storage tank low tank 2; the side surfaces of the high tank 1 and the low tank 2 of the liquid storage tank are respectively provided with a liquid level upper limit sensor, a liquid level middle limit sensor and a liquid level lower limit sensor.
A first pipeline leading to the liquid storage tank low tank 2 is arranged at the bottom of the liquid storage tank high tank 1, and a first pneumatic valve 11 is arranged on the first pipeline; the top is also provided with three liquid inlet pipelines respectively provided with pneumatic valves.
A second pipeline and a third pipeline are arranged at the top of the low tank 2 of the liquid storage tank, and a first manual valve 21 and a first nitrogen meter 22 are arranged on the second pipeline; a second manual valve 23 is arranged on the third pipeline;
a fourth pipeline leading to the liquid injection barrel 3 is arranged at the bottom of the low tank 2 of the liquid storage tank, and a third manual valve 31 is arranged on the fourth pipeline; a plurality of liquid injection pipelines connected with the liquid injection pump are also arranged below the lower tank 2 of the liquid storage tank, and each liquid injection pipeline is respectively provided with a manual valve;
and a fifth pipeline is further arranged on the liquid injection barrel 3, and a fourth manual valve 32 and a second nitrogen meter 33 are arranged on the fifth pipeline.
The working principle is as follows:
when the electrolyte needs to be recovered, shielding the liquid level lower limit sensor → opening the first pneumatic valve 11, enabling the electrolyte in the high tank 1 of the liquid storage tank to flow into the low tank 2 of the liquid storage tank through the first pipeline, then closing the pneumatic valve 11 → adjusting the pressure of the first nitrogen meter 21 on the second pipeline to a proper range → closing the second manual valve 23 on the third pipeline → opening the third manual valve 31 on the fourth pipeline → opening the fourth manual valve 32 on the fifth pipeline to be communicated with the external air exhaust → opening the first manual valve 21 on the second pipeline to enable the nitrogen to enter the low-level liquid storage tank, starting to add positive pressure to enable the electrolyte to flow into the liquid injection barrel 3 through the fourth pipeline under the action of positive pressure → observing the second nitrogen meter 33 at the same time, ensuring that the pressure value of the first nitrogen meter 22 is slightly larger than that the pressure value of the second nitrogen meter 33 → when the fourth pipeline is empty, ending the recovery, and completing the recovery of the electrolyte to, the reserve waits for subsequent reuse.
