The utility model content
The utility model is used to overcome the defective of prior art and a kind of lithium battery electrolytes device for storing liquid that can effectively avoid electrolyte to contact with air and moisture is provided.
The alleged problem of the utility model is that following technical scheme solves:
A kind of lithium battery electrolytes device for storing liquid, its special feature is: comprise liquid storing barrel in the formation, liquid storing barrel is provided with airtight top cover, the top cover place is provided with liquid feeding pipeline, aerating pipeline, the liquid storing barrel bottom is provided with liquid injection pipe, the liquid storing barrel bottom is provided with the raffinate drain tube, is provided with level indicator and relief tube in the liquid storing barrel side-walls.
Above-mentioned lithium battery electrolytes device for storing liquid is provided with liquid level control meter in the described liquid storing barrel, be respectively equipped with first, second electromagnetically operated valve on described liquid feeding, the aerating pipeline, and liquid level control meter is by the action of signal of telecommunication control electromagnetically operated valve.
Above-mentioned lithium battery electrolytes device for storing liquid, described liquid injection pipe are arranged side by side four.
The utility model divides to contact at lithium battery electrolytes and water in air and causes the harmful effect problem to improve to product quality, designed a kind of be exclusively used in the lithium battery electrolytes fluid injection device for storing liquid.This device comprises the stainless steel liquid storing barrel, liquid feeding, pressure pipeline, liquid injection pipe, relief tube and electromagnetically operated valve, liquid level control meter etc.Described apparatus structure novelty, complete function can be convenient to operation according to liquid level automatic liquid feeding in the liquid storing barrel.Use it for lithium battery fluid injection production scene, not only avoided contacting of micro-moisture in electrolyte and the air, guarantee accumulator quality, the electrolyte waste that the rinse container causes before also having avoided producing every day has reduced production cost.
