Detailed description of the invention
By reference to the accompanying drawings the present invention is described in further detail below by detailed description of the invention.
Referring to Fig. 2, is the part fluid path structural representation of reagent filling device one better embodiment of the present invention.In Fig. 1, unlabelled fine rule represents sebific duct, and the connection related in the following describes all is represented and to be connected by sebific duct.Described reagent filling device comprise the first liquid storage tank 11, second liquid storage tank 10, with the first reagent interface 17 be connected bottom the first liquid storage tank 11, with the second reagent interface 13, the reagent bottle 16 that are connected bottom the second liquid storage tank 10.Wherein, reagent bottle 16 is connected to the first liquid storage tank 11 upper opening by the first fluid path control cock 15.The bottom of the first liquid storage tank 11 is connected to the second liquid storage tank 10 upper opening by the second fluid path control cock 12.First liquid storage tank 11 is connected to the first positive pressure sources S1 and negative source S3 by the first pressure-gradient control valve 14.Second liquid storage tank 10 connects the second positive pressure sources S2.Wherein, first, second positive pressure sources S1, S2 and negative source S3 provide malleation P1 respectively, P2 and negative pressure P3, and the size of pressure P 1 is greater than the size of pressure P 2.In the present embodiment, described pressure source S1, S2, S3 are gas pressure source.
When pouring into, close the second fluid path control cock 12, open the first pressure-gradient control valve 14 and the first fluid path control cock 15, first liquid storage tank 11 internal gas pressure is switched to P3 from P1.Under negative pressure P3 effect, reagent is filled into the first liquid storage tank 11 from reagent bottle 16.
Close the first fluid path control cock 15, first pressure-gradient control valve 14, open the second fluid path control cock 12, the first liquid storage tank 11 internal gas pressure is made to be switched to malleation P1 by negative pressure P3, pressure due to malleation P1 is greater than the pressure of P2, then in the first liquid storage tank 11, reagent is perfused in the second liquid storage tank 10 under difference of pressure (P1-P2) effect.
After considering that the first liquid storage tank 11 pours into the second liquid storage tank 10, the reagent of the first liquid storage tank 11 can reduce, as continued to pour into the first liquid storage tank 11, the second fluid path by-pass valve control 12 can be closed, open the first pressure control valve 14 and the first fluid path by-pass valve control 15, make the first liquid storage tank 11 internal gas pressure be negative pressure P3, thus proceed reagent perfusion.In fact, complete the perfusion to the first liquid storage tank 11 and the second liquid storage tank 10, be substantially equal to the amount of reagent sum stored by the first liquid storage tank 11 and the second liquid storage tank 10 from reagent bottle 16 amount of reagent be filled into the first liquid storage tank 11.
Complete the perfusion of two liquid storage tanks and described embodiment to prior art below to complete to pour into the first liquid storage tank and the second liquid storage tank reagent and contrast.
In prior art, the perfusion completing two liquid storage tanks needs to pour into respectively two liquid storage tanks, assuming that it is t1 that malleation P1 switches to switching time needed for negative pressure P3, gas average discharge is Q1, and infusion time is t2; It is t3 that negative pressure P3 switches to switching time needed for malleation P1, and gas average discharge is Q2; It is t4 that malleation P2 switches to switching time needed for negative pressure P3, and gas average discharge is Q3, and infusion time is t5; It is t6 that negative pressure P3 switches to malleation P2 required time, and gas average discharge is Q4.As can be seen here, two liquid storage tank afunction times are respectively t1+t2+t3 and t4+t5+t6, and negative pressure air consumption is Q1*t1+Q3*t4, and malleation air consumption is Q2*t3+Q4*t6.
So similarly, so that in prior art, liquid storage tank switching air pressure and infusion time are for reference, state on the invention in embodiment, it is t1 that the first liquid storage tank 11 switches to switching time needed for negative pressure P3 from malleation P1, gas average discharge is Q1, and infusion time is t2+t5; Switching to switching time needed for malleation P1 from negative pressure P3 is t3, and gas average discharge is Q2.Because in the second liquid storage tank 10, air pressure is P2 all the time, therefore the reagent perfusion of the second liquid storage tank 10 does not exist because air pressure switches the time spent.
The reagent filling device first liquid storage tank 11 afunction time of the present invention is t1+t2+t3+t5, and the second liquid storage tank 10 afunction time was 0.Negative pressure air consumption is Q1*t1, and malleation air consumption is Q2*t3.Compared to prior art, reagent filling device of the present invention decreases the time of the liquid storage tank afunction caused in reagent filling process, reduces airshed demand simultaneously.In addition, the second liquid storage tank 10 need not connect negative source S3, also saves the pressure control valve between negative source S3 and the second liquid storage tank 10.
In summary, the present invention adopts that reagent container 16 pours into the first liquid storage tank 11 and the reagent filling device of the first liquid storage tank 11 to the mode that the second liquid storage tank 10 pours into can reduce the liquid storage tank afunction time, and reduce airshed consumption, cost-saving.In addition, compared with prior art, eliminate the second liquid storage tank 10 and negative pressure source S3 straight between valve, also play cost-saving effect.
In other embodiments of reagent filling device of the present invention, the number of the first liquid storage tank can be multiple, and the second liquid storage tank also can be multiple.Such as: reagent container pours into first liquid storage tank, this first liquid storage tank pours into the second liquid storage tank that multiple internal pressure is less than this first liquid storage tank, and so multiple second liquid storage tank all keeps malleation when pouring into, and has normal function.Again such as: reagent container pours into multiple first liquid storage tank, the plurality of first liquid storage tank pours into the second liquid storage tank that an internal pressure is less than the plurality of first liquid storage tank.
In other embodiments, the combination of above-mentioned several situation can also be comprised, such as: multiple first liquid storage tank pours into multiple second liquid storage tank, wherein can comprise multiple first liquid storage tank and pour into second liquid storage tank, multiple second liquid storage tank of first liquid storage tank perfusion, and first liquid storage tank pours into the combinations organizing situations such as second liquid storage tank more, only the pressure that need meet in the first liquid storage tank is greater than the pressure of the second liquid storage tank of corresponding perfusion.
