When using, vacuum-pumping pipeline 32 is connected with external vavuum pump, opens the 5th valve 43, entered by dog-house 33
Row initially feeds intake, and when the existing liquid of reactant has solid again, the first to the 5th valve 43 can be opened, by the He of dog-house 33
Feed hopper 35 is respectively to addition solid-state reactants and reaction solution in reaction vessel 31.The first to the 5th valve 43 is then shut off, is opened
Vavuum pump is opened, reaction vessel 31 is vacuumized, the vacuum in reaction vessel 31 is monitored by vacuum meter 48, when reaction is held
Vacuum in device 31 is reached after the scope of setting, closes vavuum pump, is reacted.
In course of reaction, it is necessary to in the reaction vessel 31 in negative pressure state supplement reaction solution when, open the first valve
36 and the 4th valve 42, to reaction solution is added in quantitative liquid feeding case 37, the air in quantitative liquid feeding case 37 is by the 4th valve 42
Discharge.When the liquid level in quantitative liquid feeding case 37 rises to predetermined altitude, liquid-level switch 44 is closed, so that turning circuit, makes sound
Light crossing-signal 45 sends acousto-optic prompting, and operating personnel in time close the first valve 36 and the 4th valve 42.Then the 3rd is opened
