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.

The present invention relates to a dust suppression system for use in a container, and a misting apparatus therefor. In one form, the dust suppression system comprises at least one misting apparatus for contributing to the creation of a mist layer for preventing the escape of the dust from the container, the misting apparatus comprising a means for generating an airflow, and a means for producing a mist in the airflow so that the mist is carried by the airflow.

A sealing system for connecting a bulk bag to a material handling and processing system. The sealing system comprises a main housing and a discharge tube housed within the main housing. The discharge tube is configured to fluidly connect the bulk bag with the material handling and processing system. The sealing system additionally comprises a first seal configured to selectively seal the bulk bag with respect to the discharge tube, and a second seal configured to selectively seal an interior space of the main housing from the material handling and processing system.

Embodiments of methods and systems of transferring proppant for fracking to reduce risk of production and release of silica dust at a well site are provided. An embodiment of a method can include positioning a plurality of containers each having proppant for fracking contained therein onto a conveyor at a well site, downwardly discharging proppant from each respective container of the plurality of containers, funneling proppant from the one or more outlets of each of the plurality of containers through a plurality of conveyor hoppers, receiving proppant onto the conveyor belt, conveying proppant on the conveyor to a chute, and depositing the proppant into the chute for use in a blender or other location at the well site.

A docking seal for the contamination-free connection of a first flexible casing or enveloping enclosure with a second flexible casing, comprising a first seal device which is connectable or is connected with the first casing, and a second seal device which is connectable or is connected with the second casing, wherein the first seal device includes a first docking port, a first end port and a first slider, and the second seal device comprises a second docking port, a second end port and a second slider. The invention, furthermore, relates to a docking method for the contamination-free connection of a first flexible casing with a second flexible casing with such a docking seal.

A purpose of the invention is to provide a powder supply device having a dust collection unit to collect powdery dust released when powder is supplied from a lateral side, and having a space-saving and simplified structure. A powder supply device according to the present invention has a main body, a plurality of stockers and a dust collection unit. The stocker has a charge port and a supplier. The dust collection unit has a casing, an exhauster and a filtering member. The casing has a ceiling portion and a lateral side portion, with a side opposing said ceiling portion being opened to form a lid-shaped configuration. The lateral side portion has a notched portion into which the supplier is to be inserted. The filtering member is provided inside the casing and is positioned above the notched portion and below the ceiling portion in order to collect the powder.

A sprinkler system for a temporary chute used for disposal of construction materials during a construction or renovation project. The sprinkler system is releasably engaged with the temporary chute and is used to control dust within the chute, wash down the chute, and extinguish fires. A housing of the sprinkler system is releasably engaged with an intake hopper of the chute, placing an interior chamber of the housing in fluid communication with the chutes' tunnel. First and second sprinkler heads are located within the interior chamber. The first sprinkler head is temperature sensitive and automatically actuated when a threshold temperature is crossed. The second sprinkler head is manually activated by an operator to spray liquid into the tunnel to control dust or wash the interior surfaces of the chute. The sprinkler system and temporary chute are disengaged from the building once the construction or renovation project is completed.
