Working principle: the specific usability methods of device are as follows:
1.: airtightness detection:
S1: it before use, closing solenoid valve 1, solenoid valve 22 and solenoid valve five, writes down the reading of pressure sensor 19 and is denoted as
Numerical value one opens top cover, pushes sheet metal 8 straight down by insulating bar, and motion bar 9 drives movable plate 10 to move straight down
It is dynamic, it writes down the reading of pressure sensor 19 and is denoted as numerical value two, after a period of time, write down the reading of pressure sensor 19 and be denoted as numerical value three,
Numerical value three and numerical value two-phase are same, then illustrate that 3 airtightness of dosing tank is good；
S2: then, solenoid valve 2 12, solenoid valve three, solenoid valve four and solenoid valve five simultaneously close off, and solenoid valve 1 is opened,
A certain amount of gas is added into explosive box 2 for booster pump 5, and movable plate 10 moves straight up, keeps metal plate 8 perpendicular by motion bar 9
It directly moves up, the reading of ammeter 13 increases, while the reading of pressure sensor 19 increases, then illustrates that the airtightness of device is good；
2.: give device dosing:
S1: first making movable plate 10 be moved to 3 inner wall bottom of dosing tank, closes solenoid valve 1 and solenoid valve two, solenoid valve
Three, solenoid valve four and solenoid valve five are opened simultaneously, and medical fluid is injected into dosing tank by drug-feeding tube, the medicine into dosing tank 3
Movable plate 10 moves straight up when liquid, until sheet metal 8 is moved to one 7 top side wall of resistance, close at this time solenoid valve 1,
Solenoid valve three, solenoid valve four, solenoid valve five, as shown in Figure 2；
S2: herein it should be understood that
When needing the dosing into sewage by dosing tank 3, i.e. opening solenoid valve 2 12, due to resistance 1 and resistance two
Constituent material is identical, and therefore, when sheet metal 8 moves straight down, sheet metal 8 slowly declines, power supply 14, switch, ammeter
13, the resistance value that resistance 1, sheet metal 8 and resistance two constitute closed circuit is gradually reduced, and the reading of ammeter 13 slowly increases
Add, 10 bottom outer wall of movable plate constitutes sky with 3 inner wall of dosing tank and is gradually reduced, and medical fluid gradually decreases in dosing tank 3, flow to dosing
Medical fluid outside case 3 is more, i.e., the numerical value of ammeter 13 numerical value read and the medicine liquid volume flowing to outside dosing tank 3 is in just
Than that therefore, the volume for flowing to 3 outside medical fluid of dosing tank can be determined by the reading variable quantity of ammeter 13；
3.: give sewage dosing:
It is determined according to pollutant load in the volume of sewage and sewage and needs to add the volume of medical fluid, such as the S2 in 2.,
The numerical value of numerical value and the medicine liquid volume flowing to outside dosing tank 3 that ammeter 13 is read is proportional, therefore it can be concluded that plus medical fluid
The numerical value of ammeter 13 afterwards closes solenoid valve 2 12 when ammeter 13 reaches specified value, realizes high-precision add
Medicine reduces the consumption of medical fluid, has saved use cost under the premise of guaranteeing pollutant in sewage.
