Cleaning System Operation
The RF cleaning system automatically cleans each bag at
least once every four minutes. During the filter cleaning cycle,
a solid-state timer is used to energize a solenoid valve and
controls the open and close time of the diaphragm valve. An
air reservoir stores the pressurized air. When the solenoid is
activated,
the diaphragm valve opens and a high volume of pressurized
air is directed through the manifold arms and into the filter
bags dislodging the dust cake. The dislodged dust cake then
falls into the hopper where it is discharged into a drum or bin,
rotary valve, screw conveyor, or pneumatic conveying system.
