Dust Collectors type K ..

K 15

    The model K .. is a heavy duty reverse pulse-jet dust collector that operates continuously without requiring the process to be shut down for cleaning.  It is automatically self-cleaning while removing dry dust from an airstream.  It is a versatile unit that can handle almost any type of dust.  With our cleaning system operate at very high efficiencies and, for most aplications, can operate very reliably with much less filter media than any other commercially available collector in its class.

    Cylindrical fabric filter bags with bottom discs are manufactured from felted cloths and are supported on the outside of cylindrical wire cages. The dust collects on the outside surface of the cloth.

    Dust laden air enters the unit through a high inlet designed to reduce upward internal velocities which are prevalent in bottom entry collectors.  Power Robotics designs have improved the high inlet by incorporating a dropout section and perforated baffle plate causing velocities to be lowered at the entry to the collector. This feature allows heavier mass dust particles to drop out into the hopper and reduces the amount of dust carried to the filter media.  Controlling velocities and direction of air movement within a dust collector are very important to the efficiency of the unit as they reduce               re-entrainment of dust.
Diaphragm Valves
Manual Discharge Valve

    Power Robotics cleaning mechanism generates a short powerful burst of induced air flow into the top of the bag. These bursts reverse the air flow momentarily flexing the fabric bags to knock off excess dust agglomerated on the top layer of the filter cake while maintaining a functional filter cake. The purge tube with high velocity nozzles is positioned directly over the openings at the top of the bags. Each purge tube is connected to a large fast-acting diaphragm valve on the outside of the collector. These diaphragm valves are pneumatically operated and actuated by direct acting solenoid pilot valves, controlled by an adjustable electronic timing panel.

    The high velocity nozzle allows Power Robotics to eliminate the venturies used in most generic pulse-jet collectors. Venturies can restrict filtering velocity, impede cleaning, and cause puffing and abrasion around the top of the bags. With the high velocity nozzle, our cleaning system is able to use higher air-to-cloth ratios and less compressed air while inducing more air per cubic foot of compressed air than plain orifices, conventional converging nozzles, or straight nozzles.
