Abstract
PURPOSE: To feed dust constantly into a measuring chamber by producing dust spray within the tank of a dust generator with air blow and feeding the air intermittently into the tank through the solenoid valve to generate constant dust spray at any time.
CONSTITUTION: When a solenoid valve 11 is ON, air 6 is fed into a tank 19. And when the solenoid valve is OFF, a part of the air 6 is fed back from the tank 19. At this time, air 7 is returned through a hose 16 and exhausted out to the outside as air 8. Thus, air holes produced among dust 20 are broken by the return of the air. In such a way, air intermittent feeding allows to make dust spray 21 constantly, so that the interior of the tank 19 is filled with the dust spray 21 at any time and then the constant dust spray can be fed into a measuring chamber.
