OPERATION
Operating the Expanded
Aspirator.
The Expanded Aspirator is designed to pull bees wings, chaff, and
dust from the grain during filling and emptying of the dryer. The
Aspirator utilizes a vacuum force to create suction on the fill and
discharge auger boxes. This suction force carries the debris from
the dryer through the T-valve and fan, and expels it through the
cyclone.
Test the system.
The Aspirator unit should be tested upon completion of the
assembly and wiring process. It should also be tested at the
beginning of every operating season.
For safety reasons the dryer should not be running during this
check.
Stop the dryer.
Lockout power to all components except the
3 hp Blower Unit.
Check that all bolts and clamps are in place.
Check that the motor is wired correctly.
Close the
Butterfly Vent.
Start the Blower.
Check that air is being pulled out of the discharge.
Check that air is being pulled out of the fill hopper box.
Check that air is being vented out of the cyclone.
Open the
Butterfly Vent.
Check that air is flowing into the vent.
IF air is not moving freely through the components,
THEN check for leaks or a blockage in the tube.
Check that the T-valve rotates freely and provides proper settings.
Expanded Operation.
Run the
Expanded Aspirator Unit
when the dryer is in operation.
Open
the
Butterfly Vent
to
decrease
the suction force at the
discharge auger box.
Close
the
Butterfly Vent
to
increase
the suction force at the
discharge auger box.
Periodic Maintenance.
Check the component parts periodically for buildup of material or
excessive wear.
Components free of buildup work more efficiently and last longer.
Replace worn out parts to obtain the best operating performance.
T-valve Control Settings.
Align the arrow on the inner can with the word
"BOTH"
on the
outer can to provide suction to both the top and the bottom.
Align the arrow on the inner can with the word
"TOP"
on the
outer can to provide suction to the top only.
Align the arrow on the inner can with the word
"BOTTOM"
