Description

PEBCO® recently introduced the patent-pending, Self-Contained Dustless Loading System, or SCDLS, a system featuring both a dust collector and a loading spout in a fully integrated housing for loading dry, dusty materials into trucks and railcars.

Previously, PEBCO®’s standard integral dust collector (IDC) had an overall height of ~46” and the competitors’ measure approximately 32”. This limited the installation of integral dust collectors in existing loading systems that did not have a dust collection feature, but was looking to add it. The dust collection feature on PEBCO®’s SCDLS-22 adds only 20 ½” to the overall equipment stack-up, making it possible to replace almost any existing loading system with a PEBCO® SCDLS. In new projects, the reduced height also reduces the costs associated with steel structure and material transport systems.

The SCDLS was developed in collaboration with Donaldson/Torit.

Other features of the SCDLS include:
• Environmentally-responsible loading of dry, dusty materials
• Innovative, and low profile
• Industry minimum overall height
• Field replacement possible for almost any existing loading system that does not currently include a dust collection feature
• Power Core Filter cartridges available in conventional and static dissipating
• Donaldson/Torit’s proprietary Power Core filter media and pulse system
• Dust collection cartridges easily replaced through side access panels with no special tools required
• All wear components are bolt in for ease of replacement

Fan Assembly Receiver Inlet . Blow Down Valves Electrical Box 5

INLET The inlet can be constructed of different materials depending on the product’s  abrasiveness,  corrosiveness,  -or temperature. 6

RECEIVER The receivers store compressed air that is used in the cleaning cycle of filter cartridges. 7

BLOW DOWN VALVES  Goyen Brand  Pilot operated  High volume, short duration blast of air 8

AIR INLET Standard port, 1” npt 9

GAUGE PORTS  Ability to use air pressure gauge to confirm adequate air pressure for blowing material from the cartridges  Designed for minimum of 60 psi, preferred 80 psi 10

CONNECTION HOSE Connection Hose between receivers Only 1 plant air connection is required, because receivers are connected through this hose. 11

PRESSURE DIFFERENTIAL SENSOR Pulse cleaning can be controlled by a timer or differential sensor. Pressure Differential Sensor senses the difference between “dirty air” side above the cartridge verses the “clean air” side of the cartridge to “know” when cartridges need cleaning. 12

PRESSURE DIFFERENTIAL SENSOR  3” W.C. for cleaning pulse  5” W.C. for cartridge replacement  Truck loading is normally based on timing sequence 13

FAN ASSEMBLY Fan Assembly pulls air up through the annulus and in through the cartridges so only clean air travels through the fan assembly. 14

FAN ASSEMBLY Fan Size is based on up to 500 cfm per cartridge: DLS Size # Cartridges DLS-22 2 DLS-33 3 DLS-39 4 DLS-44 6 15

DAMPER The damper regulates flow through the collector, adjusting the damper increases or reduces the air flow to provide optimal dust control by the SCDLS. 16

OPTIMAL PERFORMANCE Defined as:  minimal dust is pulled into the cartridge while no dust escapes into the atmosphere -and capturing the dust but not capturing the product. If loading low density, small particles, shutting the damper reduces the potential to pull too much air through the cartridge, capturing the product. 17

RELAY LIMIT SWITCH ACCESS PANEL 18

PULLEY SYSTEM & RLS 19

PULLEY SYSTEM Single wrap radius ensures consistent pull between all three pulleys for even raising and lowering of the spout. 20

SENSOR CONNECTION Connection for “dirty air” differential pressure switch 21

ROTARY LIMIT SWITCH Chain drives RLS Stops the motor/reducer when the chute is either fully retracted or fully extended, limits the up and down travel. 22

ROTARY LIMIT SWITCH Contact block opens circuits and stops at adjusted settings Adjusts points on the rotary limit switch 23

ROTARY LIMIT SWITCH First, loosen the set screw. Second, adjust the up travel (with the left) or down travel (with the right) until it clicks. “Set Screw” 24 Last, retighten the set screw.

SLACK CABLE LIMIT SWITCH Slack Cable Limit Switch is used to limit the extended position of the spout. 25

SLACK CABLE LEVER ARM Cable Captivator Senses when the cables go slack and stops the down travel of the spout 26
