Second pressure gauge 24.
Oxalic acid extracts is equipped with third electrically operated valve 31, third pneumatic operated valve 32, third pressure regulator valve successively from left to right on branch 3
33 and third pressure gauge 34.Drain branch 4 is equipped with the 4th pneumatic operated valve 44.
It is equipped with nozzle 10 on the roof of 5 inner cavity of container, rinses branch 1 and is connected with nozzle 10.
It is equipped with overflow branch 9 on the top of container 5, overflow branch 9 is connected with drain branch 4, is set on overflow branch 9
There is the 5th pneumatic operated valve 95.
In use, the first pressure regulator valve 13 of adjustment to first pressure gauge 14 is setting value before measuring, wherein the first pressure regulator valve 13
Range of set value is 0.3~0.5Mpa, and the range of set value of first pressure gauge 14 is 0.3~0.5Mpa.Open the first pneumatic operated valve
12 and pure water is injected, rinse branch 1 and container 5 is rinsed by nozzle 10, in flushing process, opened on drain branch 4
4th pneumatic operated valve 44.It rinses 3~5 times, you can rinse the oxalic acid in container 5 well.
After the completion of flushing, the first electrically operated valve 11 is closed, opens the second pneumatic operated valve 22 on inflation branch 2, adjustment second
Pressure regulator valve 23 to second pressure gauge 24 is setting value, wherein 23 range of set value of the second pressure regulator valve is 0.15~0.3Mpa, second
The range of set value of pressure gauge 24 is 0.15~0.3Mpa.To being inflated in container 5 until the numerical value of second pressure gauge 24 is steady
It is fixed, close the second pneumatic operated valve 22.
Branch 3 is extracted by oxalic acid and extracts oxalic acid out of automatic production line stores oxalic acid container, and it is pneumatic to open third
