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 filtering and collection system for filtering dust and other debris particles from an incoming dust laden air stream, such air stream generally being used for conveying granular material into or from a bulk tank trailer, a railroad car, or other conveying vehicle, the filtering system designed to be functioned by vacuum air pressure, operatively generated by a blower, to draw in the soiled air into the filter system, to cleanse such air for further use in the conveying of the granular material. The air flow may be reversed, to provide for a dislodging of any dust particles from the filtering system, and to cleanse the filter for further efficient usage of the system in conveying granular material into or out of the tank trailer, or other vehicle during usage. The filter system includes a pod of filter tubes encapsulated by a polymer header that mounts to a transverse plate that secures to the approximate upper end of the filter canister of the filtration system.

A spray trough is described herein, including a trough body, wherein the trough body has a bottom portion, a first side portion, a second side portion, a front portion, and a back portion, the bottom portion, the front portion, and the back portion each having a first end and a second end, a top plate having a first end and a second end, wherein the first end of the top plate is fixedly attached to the second end of the back portion, wherein the top plate extends substantially perpendicular from the second end of the back portion, and a deflector plate, wherein the deflector plate is attached to the second end of the front plate, wherein the deflector plate extends downwardly from the second end of the front plate, such that the deflector plate angles towards the front portion.

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 invention relates to a discharging apparatus for discharging loose and in particular pulverulent material that is hazardous to health from rigid or flexible containers (12), in particular bags and barrels (13), comprising a discharge chamber (2) which has a discharge opening (5) for discharging the material after removal from a container (12) and which additionally has an insertion opening (3) for at least partial insertion of a container (12) into the discharge chamber (2). According to the invention, the discharge chamber (2) has a ventilation opening (4) which is arranged at a side of the discharge chamber (2) opposite the insertion opening (3) and which is connected to pump means (10) in such a way that an air stream can be generated inside the discharge chamber (2), which causes a laminar air flow starting from the insertion opening (3) and leading in the direction of the ventilation opening (4).

In accordance with embodiments of the present disclosure, systems and methods for passively reducing or preventing dust formation in a particulate handling system are provided. In some embodiments, the handling system includes a silo for holding bulk material used to form a well fracturing treatment fluid. The silo may include a chute to deposit a portion of the bulk material from the silo into a blender and a cyclone mounted to the silo to separate dust from a pneumatic air flow and to release a substantially clean air into the atmosphere. In other embodiments, the handling system may include a horizontally oriented cyclone assembly mounted to a blender storage tank, cyclone assembly including a horizontally oriented cyclone separator to separate dust from a pneumatic airflow and a dust collection container to receive the dust and output the dust into the storage tank.

A delivery system for feeding particulate matter to a target location at a well site, including a transportable conveyor belt assembly; one or more silos in fluid communication with a particulate supply line, each of the silo inlets extending through a side wall of the respective silo and disposed at a different location from the others along a longitudinal axis of the respective silo; and for each silo an enclosed chute detachably attachable thereto so as to receive into the chute particulate matter gravity fed out of the respective silo and convey such matter into the housing of the conveyor belt assembly. The silos, the chutes and the housing enclose the particulate matter as it passes from the silos through the chutes and conveyor belt assembly to the target location, to inhibit the release of dust generated from movement of the particulate matter from the silos to the target location.

According to embodiments of the present invention, a material transfer station provides a base frame equipped with a table member, a container tipper, an operator interface, and a connection to a power source. In operation, a destination container is positioned beneath the table member, and the container tipper holds a supply container. Solid matter may be conveyed from the supply container into the destination container through an opening in the table member. Modules may be attached to provide additional functionality, such as a receiving module, a containment module, a vibratory screener, a flexible film isolator, and a nitrogen purge system.
