Description
Technical field
The present invention relates to device for storing liquid technical field, especially a kind of Two Layer Liquid Tank.
Background technique
The fluid reservoir of existing battery electrolyte is all single layer structure, can only be used in specific environment, as electrolyte can only
It is used in glove box, drying shed, qualitative change can be generated and liquid temperature reduction after equipment stopping because electrolyte is contacted with air
It generates difference variation to be all easy to cause failure to topping-up pump, and tank body fluid infusion needs manual operation and liquid into fluid reservoir
It is more without time of repose liquid bubble, influence the precision of fluid injection weight.
Summary of the invention
The purpose of the present invention is to overcome the shortcomings of the existing technology, provides a kind of bilayer for improving fluid injection precision and applicability
Fluid reservoir.
The purpose of the present invention is achieved through the following technical solutions: a kind of Two Layer Liquid Tank, including upper layer tank body and lower layer

Second tapping valve, the second liquid feed valve pass through the first tapping valve of piping connection.
The upper layer tank body is fixed by the bracket the top for being installed on lower layer's tank body.
The Two Layer Liquid Tank further includes PLC, first liquid feed valve, vacuum valve, the first tapping valve, the first liquid level
Sensor, the second liquid feed valve, pressurizing valve, the second liquid level sensor and the second tapping valve are electrically connected with PLC respectively.
Upper layer tank body and lower layer's tank body are all-sealed structure, the meeting when topping-up pump carries out drawing liquid from the second tapping valve valve port
To when generating negative pressure (vacuum values) and negative pressure in lower layer's tank and reaching certain value, it may appear that fluid injection pumping motionless liquid and the liquid taken away
Body weight is not right.In view of the above-mentioned problems, we install constant-voltage system additional to fluid reservoir, when pressure sensor detects lower layer's tank negative pressure
After reaching certain value, opens lower layer's tank pressurizing valve and supplement pressure is carried out to lower layer's tank, closed after reaching predetermined value, to realize
Automatic constant-pressure function, predetermined value are set by pressure sensor.
The present invention can automatic liquid supply, the course of work are as follows: first open vacuum valve and tank body is vacuumized (for electrolysis
Liquid partially liq can generate rotten after contacting with the air) reach and stops after a certain period of time, the first liquid feed valve is opened to upper layer tank body
Fluid infusion is carried out, liquid, which reaches, (passes through the first liquid level sensor induction level) when setting lower liquid level, opens the first tapping valve under
Layer tank body carries out fluid infusion, and when lower layer's tank level reaches setting liquid level, the first tapping valve is closed, when tank liquid arrival in upper layer is set
Surely the first liquid feed valve is closed when upper liquid level, and when lower layer's tank level reaches liquid level under setting, the first tapping valve is opened to lower layer's tank
Body carries out fluid infusion, when tank body liquid reaches liquid level under setting when upper layer, opens the first liquid feed valve and carries out fluid infusion, liquid to upper layer tank body
Body closes the first liquid feed valve, to realize automatic fluid filling function to when setting upper liquid level.
The effect of double layers of tank body is that, when liquid enters tank body by high pressure or high speed, can generate many bubbles, bubble
The weight that liquid can be extracted to topping-up pump generates variation.And it is divided into two tank bodies, upper layer tank body becomes a buffer tank, and liquid exists
When upper layer tank body is stood by the regular hour and liquid low speed flows into lower layer's tank body, a large amount of bubbles can be eliminated.
The first heating tube and the first temperature sensor, setting in lower layer's tank body are provided in the upper layer tank body
There are the second heating tube and second temperature sensor.
Since electrolyte is easy crystallization when certain temperature difference or low temperature, thus be easy to cause failure to topping-up pump, because
We install constant temperature system additional to fluid reservoir for this.The working principle is when the first liquid level sensor or the second liquid level sensor are examined
When having measured liquid, the corresponding intracorporal heating tube of tank heats liquid by temperature sensor setting value, when temperature reaches
It closes when the upper limit when setting value, starts when temperature is lower than lower limit, to reach automatic constant-temperature function, to avoid topping-up pump event
Barrier.
The invention has the following advantages that
The present invention can overcome fluid infusion to generate the defect of aeration fluid injection precision by setting double layers of tank body；Leakproofness
Can be good, it will not generate and contact with air；Pressure is constant in maintenance lower layer's tank body, eliminates pressure change to the bad shadow of fluid injection
It rings；Heating device is set, the universal performance of device is enhanced.
