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 dry material delivery system adapted for unloading dry bulk material from a container. The system includes a dust collector unit and a main vacuum line connected to the dust collector unit. The vacuum line is attached to a vacuum source to pull a vacuum on the dust collector unit. The system includes a discharge unit attached to the container such that the discharge unit is movable. There is a connection between the dust collector unit and the discharge unit such that the applied vacuum by the main vacuum line causes suction to pull dust from the discharge unit. The system includes a product hose connected to the discharge unit that is also attached to a product discharge of the container to allow flow of dry bulk material from the container to the discharge unit.

A method for manufacturing a panel and a dust-free system for manufacturing a panel are provided. The method includes several operations. A first operation on a substrate in a first machine station is performed. A second operation on the substrate in a second machine station is performed. The substrate is transferred between the first machine station and the second machine station, wherein the substrate is transferred in a mini-environment by a panel carrier.

Embodiments of the present disclosure a system for capturing proppant dust particles when positioned at a fracking operation site including a proppant delivery assembly to receive one or more containers having proppant stored therein. The system dispenses the proppant from the one or more containers and delivers the proppant to other fracking operation equipment. Moreover, the system includes a dust collection assembly positioned proximate and associated with the proppant delivery assembly to capture dust particles released by movement and settling of the proppant when being dispensed and delivered by the proppant delivery assembly. 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 to fracking operation site personnel.

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 dust filtration unit for a frac sand storage bin and a method for using the same is disclosed. The dust filtration unit includes an adapter base adapted for attachment to an opened inspection hatch on the sand storage bin, a diffuser manifold attached to the adapter base, and a top plate of the diffuser manifold defining a plurality of filter bag orifices. Each of a plurality of filter bags is releasably attached to one of the plurality of filter bag orifices. In a non-limiting embodiment, the dust filtration unit further includes a hinge between the adapter base and the diffuser manifold, wherein the hinge rotatably attaches the adapter base to the diffuser manifold.

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.

A temporary, non-fixed partitioning system includes a common assembly bracket that can be readily assembled with a wall panel formed of various standard dimensioned building supplies. The wall panels may include a standard door slab, a standard window sash, standard dimensional lumber, a peg board, a chalk board, a whiteboard, a corrugated cardboard panel, a foam board, a gator board, a fiberglass panel, a cork panel, a plastic panel, an upholstered panel, a wood panel, and an acrylic-based or silica-based glass panel, and may also be suitable for receiving custom or desired printing of designs, indicia or other nomenclature. The partitioning system could be provided in a kit form with a plurality of common assembly brackets and wall panels, which are reconfigurable for a variety of uses such as co-working space, trade show booths, or lobby displays.

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.
