A dust capture and reclamation system for a rubber conveyor belt having a housing for mounting over a portion of the rubber conveyor belt, a plurality of idler roller assemblies, a plurality of return roller assemblies, a trough for mounting under the rubber conveyor belt to catch granular material falling from the rubber conveyor belt, the trough having an inside surface, a mechanism for moving granular material along the inside surface to a collection point, a first access panel through one side for accessing an idler roller, and a second access panel through one of the pair of opposed side walls for accessing a return roller assembly.

A truck dumper including a material receiving hopper, a tilt table configured to dump a load from the truck or truck trailer into the material receiving hopper. The invention includes a stilling shed positioned above the material receiving hopper and at least one curtain baffle suspended below the roof of the stilling shed. The curtain baffles are positioned such that there is a gap located near the roof and an upper margin of the at least one curtain baffle through which air can flow. The invention further includes an air exhaust structure configured to exhaust dust laden air from the interior of the stilling shed.

The present disclosure is directed to a big-bag transfer station for API seed crystals. The transfer station may permit the filling of smaller containers, such as bags or pouches, from a large container, such as a big bag. The transfer station may permit the transfer without contaminating the atmosphere of the room in which the station is housed. Additionally, the transfer station may limit cross-contamination between filling cycles by employing single-use liners.

Controlling the dust emissions from the discharge of bulk materials from a container provides many benefits. A container engages a support structure that includes a frame. The frame includes a dust control enclosure coupled to an outlet or a hopper at the top of the frame and the container or a discharge gate of the container. The dust control enclosure comprises a collapsible and flexible material so that a tight seal is formed between the container and the hopper or the outlet of the frame. Dust from the discharged of the bulk material from the container is contained within the support structure. A dust control panel may also be disposed at the top of the frame to prevent any dust from migrating through the frame. The container may comprise a plurality of dust enclosure panels to further prevent the escape of dust during discharge of the bulk material.

A proppant delivery assembly receives and supports a plurality of containers having proppant stored therein. A cradle has a top surface which receives and supports the plurality of containers when positioned thereon. The cradle enables the plurality of containers to dispense the proppant stored therein. A proppant mover is positioned to underlie and extend along the top surface of the cradle aligned with the plurality of containers to receive proppant from the plurality of containers. The proppant mover carries proppant away from the plurality of containers. A chute is coupled to the cradle for receiving proppant from the proppant mover and directing the proppant to a blender hopper. A hood assembly is disposed at an end of the chute opposite the proppant mover for directing a vacuum air flow that removes a volume of air containing proppant dust particles directed from the chute. The hood assembly includes a curtain extending about a perimeter of the hood assembly and downward therefrom to at least partially define the volume of air being removed by the hood assembly.

A truck dumper including a material receiving hopper, a tilt table configured to dump a load from the truck or truck trailer into the material receiving hopper. The invention includes a stilling shed positioned above the material receiving hopper and at least one curtain baffle suspended below the roof of the stilling shed. The curtain baffles are positioned such that there is a gap located near the roof and an upper margin of the at least one curtain baffle through which air can flow. The invention further includes an air exhaust structure configured to exhaust dust laden air from the interior of the stilling shed.

A system is disclosed for conveying proppant from a container to fracking operation equipment. The system includes a proppant delivery assembly having a frame supporting the container adjacent a proppant mover having a conveyor, a shroud enclosing a portion of the conveyor, a proppant chamber coupled to the shroud and a chute coupled to the proppant chamber. The system also includes a dust collection assembly fluidly coupled to the proppant mover to collect the dust particles contained therein. The dust collection assembly includes an air mover, a hood with a dust receptacle, and ductwork coupling the air mover to the dust receptacle. An air flow is generated along a flow path through the dust receptacle and the ductwork to the air mover such that a suction pressure generated by the air mover is sufficient to only capture and remove the dust particles, thus reducing a risk of capturing the proppant.

Embodiments of the present disclosure describe a system for capturing dust and dust-laden air caused by the agitation, movement or transfer of particulate material. The system includes a dust collection assembly positioned proximate and associated with the delivery of particulate material to capture dust particles released by movement and settling of the particulate material when being dispensed and delivered. The dust collection assembly is positioned to direct an air flow in a flow path overlying the dust particles to capture the dust particles and move the dust particles away from the proppant thereby reducing risk of dust exposure.
