In one embodiment, said controller 40 comprises the timer that makes interval certain hour between the operations, makes between operations such as said each item solution conveying, pumpback, all the interval schedule time, makes the operation of solution-stabilized back more accurate.
Consult Fig. 3, the present invention also provides a kind of solution quantitative carrying method embodiment, adopts the container 10 that is provided with bottom valve, comprising:
Step 301: the valve of closing said container 10 bottoms;
Step 302: add solution in the said container 10 and overflow said container 10 until solution;
Step 303: with the level that is lower than said solution spillover position is that liquid sucting port detaches said container 10 with solution; Distance preestablishes between wherein said liquid sucting port and said container 10 bottoms, and sets the solution quantity of capacity for needing to carry that is limited between liquid sucting port and container 10 bottoms;
Step 304: open said valve, let said container 10 interior solution all flow out to the destination.
The present invention designs the position between outgate 11, liquid sucting port, the container 10 dexterously; Utilize above-mentioned position relation, add solution for 10 li toward container earlier, at the liquid sucting port level attitude solution is detached container 10 then; Owing to detach solution in this at; Can only detach the solution on this level and keep the solution under this level, and the solution under this level is the solution quantity that needs conveying the solution capacity that is limited between said liquid sucting port and said container 10 bottoms then; Open the valve of container 10 bottoms, can utilize the solution that stays of said setting solution quantity.
Therein among embodiment; In said two steps: add solution in the said container 10 and overflow said container 10, be that liquid sucting port detaches solution between the said container 10 with the level that is lower than said solution spillover position until solution; And in said two steps: be that liquid sucting port detaches solution in said container 10, opens said valve and let solution all flows out between the destination in the said container 10 with the level that is lower than said solution spillover position, equal schedule times at interval.
Above-mentioned with solution from the step that container 10 detaches, the speed of detaching that slows down gradually the period that can in the end be about to exhaust so that solution keeps stable in container 10, and was unlikely to take out.
In one embodiment; Said liquid pumping device 20 is that common liquid medicine adds pump, and liquid delivery tube 22 pipes such as grade can be flexible pipes, and 10 in container can be a PVC material graduated cylinder; Protective case 60 is graduated cylinder PVC material protection covers 60; Counter flow pipe 50 can be an overflow pipe, and electric control valve 30 is electromagnetic valves, and source of solvent is the liquid medicine storage barrel.
Working process: like figure; When controlling to, computer program adds liquid medicine during the time; Liquid medicine adds pump starts working, and to the graduated cylinder of B outlet, this process setting time guarantees can graduated cylinder be taken out completely to be had to such an extent that residue just can (about 1 minute) from A inlet suction liquid medicine; Do not need accurately, electromagnetic valve is a closed condition in this process.
Next, the liquid medicine residue from the B outlet just is back to the liquid medicine storage barrel to be added from the C outlet through overflow pipe.In about 1 minute of above time.Next computer control liquid medicine interpolation blowback is taken out; Promptly from graduated cylinder, taking out solution through the B mouth exports to A; About 1 minute of this time (to add pump just require can exhaust in 1 minute can), when the liquid medicine liquid level exported near B in being extracted into graduated cylinder, remaining liquid medicine just was retained in the graduated cylinder.
Last step waits to add and takes out liquid medicine and accomplish back (about 3 minutes) to pumpback liquid medicine, and the computer control electromagnetic valve was opened in the 4th minute, and liquid medicine joins in the production groove through the D outlet in the graduated cylinder.Whole interpolation process is accomplished.
In addition, through adding the height of B outlet in the graduated cylinder, can regulate each liquid medicine addition.
