The course of work of the present embodiment:
Controlled valve is when the quantitative priming device of lithium battery electrolytes is started working, for starting state, thus control inputs pipe can box house input electrolyte in the past, and the process that electrolyte is injecting, owing to there is constant temperature heating plate in cabinet wall, so the temperature signal detected at temperature sensor is transferred to master controller, master controller then controls constant temperature heating plate and carries out work, the set point of temperature effect ensureing electrolyte is at any time played by this mechanism, also have an effect can ensure that the volume of the electrolyte being injected into box house will cause the change of bulk density excessive because the change of temperature is excessive exactly,
And the detecting head of liquid density sensor can measure the density case of the electrolyte of injection timely, this situation also can be transferred to master controller, due to before in master controller input need to inject electrolyte content, so at this moment just can calculate according to the relation of density and volume and weight the height that electrolyte needs to be injected into box house;
And control machine operation, thus the rotation of driven gear tooth bar, will relative movement with position in casing of the anode bar of tooth bar, until stop when moving to the position height calculated, due to the stopping of gear, the anode bar with tooth bar also can be fixed on certain position height;
Therefore, when the height adjusted before the liquid level arrival of the electrolyte that input pipe injects, both positive and negative polarity rod will be communicated with, thus Node Switch will be opened, and the controlled valve controlled by Node Switch is closed, thus stops injection electrolyte to box house;
When controlled valve closes, master controller just can control pneumatic flow-limiting valve and open, thus electrolyte will from box house flowing out by liquid injection pipe at the uniform velocity, the benefit at the uniform velocity flowed out is exactly can reduce electrolyte inside enter too much air and ensure the consistency of the strength of fluid of electrolyte simultaneously.
