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.

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.

Systems and methods for dispensing dry flowable materials used in wellbore operations. In some embodiments, the methods include: providing at least one vessel that contains dry flowable materials, each vessel including an outlet connected to a common vacuum manifold; providing a vacuum source for directing a flow of the dry flowable materials from at least one vessel to the common vacuum manifold; discharging the dry flowable materials from the vessel to the common vacuum manifold through an outlet connected to at least one vessel, wherein a discharge valve is disposed on the outlet; determining an amount of dry flowable materials in at least one vessel at least in part using at least one load cell disposed underneath the vessel; and determining the amount of dry flowable materials being routed to the common vacuum manifold based at least in part on the amount of dry flowable materials measured in the vessel.

The present invention discloses a feeding system that comprises a plurality of material tanks having air outlets, a plurality of blowers, a dust remover having an air inlet, and a connecting pipe. Air inlets of the plurality of blowers are in communication with the air outlets of the material tanks in one-to-one correspondence. The first end of the connecting pipe is in communication with the air inlet of the dust remover, and the second end of the connecting pipe is movable between being connected with the air outlet of a first one of the plurality of blowers and being connected with the air outlet of a second one of the plurality of blowers. The disclosed feeding system has a simple structure and zero dust leakage. Also disclosed is a glass production apparatus that comprises the disclosed feeding system.

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.

An apparatus for rotary dumping of rail cars, including a material receiving pit. A rotary rail car dumper includes a rotational frame supporting at least one baffle. The rotational frame is configured to dump a load from a rail car during rotational motion of the rotational frame between an upright position wherein the entire load is in the rail car and a dumping position wherein the load can exit the rail car. A backside airflow diverter is located beneath the rotational frame and includes a curved upper surface. A lower margin of the at least one baffle contacts the curved upper surface during at least part of the rotational motion of the rotational frame.

The invention relates to a connecting device (2) for connecting a container (F) containing a powder/granular product to an isolator (1) with a connecting opening (120), through which the container (F) is introduced into the isolator (1) for emptying as intended, wherein the connecting device (2) comprises: a holding device (220) being configured to receive the container (F) and hold it during connecting and emptying; a transfer device (210, 230) for transferring the holding device (220); and a control device for controlling the transfer device (210, 230); wherein the control device is configured to control the transfer device (210, 230) in such a way that it transfers the holding device (220) together with the container (F) from an initial holding position in which the container (F) is received in the holding device (220) as intended, into an emptying position such that at least an opening of the container (F), via which the powder/granular product is removed for emptying the container (F) as intended, is introduced into the isolator (1) through the connecting opening (120).

Apparatus and method for reducing airborne proppant adjacent a fracking material handling system. In some embodiments, a proppant storage chamber is configured to store a volume of proppant. A blow-in adapter mates with a first port of the chamber to facilitate a flow of proppant into the chamber at an inlet pressure. A filter assembly covers and filter a first aperture of the chamber to reduce an emission of airborne proppant during the transfer of the proppant into the proppant storage chamber. A vacuum adapter mates with a second port of the chamber to supply a negative pressure to the chamber during the filling process to maintain an internal pressure within the chamber below a predetermined pressure threshold.

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.
