A bulk material shipping container including a pallet, a compartment configured to receive, hold, and release loose materials and connected to and supported by the pallet, a material unloading assembly positioned under a bottom portion of the compartment, configured to facilitate the release or unloading of loose materials from the compartment, and connected to and supported by the pallet, and a material loading assembly configured to facilitate the loading of loose materials into the compartment and connected to and partially supported by a top wall assembly of the compartment.

A fitting prevents the unintentional flow of flowable material out of a container through a valve. The valve comprises a housing, a flow control element rotatable between an open configuration and a closed configuration, and an actuator for moving the flow control element, wherein the fitting is adapted for insertion into the housing which in use locks the flow control element in a closed configuration by preventing rotation of the flow control element.

A bulk fluid storage container has a top wall structure and a bottom wall structure held in spaced relation by a side wall structure. An internal baffle assembly is disposed in the fluid storage volume between the side wall structure for reducing fluid sloshing. A fill port formed in the top wall structure has a fill flange for coupling with a source of the fluid. A vent port formed in the top wall structure has a pressure vacuum value. A drain port formed in the side wall structure in a lower region adjacent the gutter region has a drain valve assembly is coupled to the drain port. A frame assembly includes an upper rectangular frame member and a lower rectangular frame member arranged in spaced relation by a plurality of post; wherein the frame assembly surrounds and supports the fluid storage vessel.

The present invention is a new method to efficiently reclaim cement from a horizontal warehouse. This new reclaiming method combines a mechanical cement reclaiming machine, together with a reduced amount of open air slides. Material is fluidized through a porous media with low pressure air. Material flow is achieved by sloping the Air slide conveyor to match the fluidized angle of repose of the powdered material. Further, the present invention introduces a conveying system, comprising a cascade of open and enclosed air slides and elevator machines, to convey the cement from the reclaiming area to a dispatch hopper. The introduction of these components, together with cement stacking and dispatch systems, is a Fully Automated Cement Horizontal Storage system and method.

An alternative bottom drop and straight tee discharge from bulk tank conveying granular material, the tee having extensions for the automatic and manual operations of a disc valve, pivotally located within the horizontal section of the tee, during functioning. The disc valve may be manually operated, or pivoted through motorized operations, to allow for the alternative flow of bulk material from the vehicle hopper. The disc valve has an annular disc, integrally formed with upright supports, that are bearing mounted by shafts to the sidewalls of the structured tee.

A wet sand delivery and conveyor apparatus ships wet proppant from a sand mine wet plant to a well fracturing site and delivers the wet proppant directly to the well site. The wet sand delivery and conveyor apparatus comprises a multi-container support frame, which is mounted on a trailer bed, a plurality of containers mounted to an upper portion of the frame, and a conveyor belt mounted on the frame below the plurality of containers and positioned to receive proppant released in a gravity pour from the containers onto the conveyor belt. An auger mounted near an end of the conveyor belt is also provided to transfer sand from the end of the trailer bed to a position extending diagonally upward and away from the trailer bed to drop sand into a vessel or sand deposit site positioned underneath an upper end portion of the auger.

A bulk material shipping container including a pallet, a compartment configured to receive, hold, and release materials and connected to and supported by the pallet, a material unloading assembly positioned under a bottom portion of the compartment, configured to facilitate the release or unloading of materials from the compartment, and connected to and supported by the pallet, and a material loading assembly configured to facilitate the loading of material into the compartment and connected to and partially supported by a top wall assembly of the compartment.

In accordance with presently disclosed embodiments, systems and methods for managing dry bulk material efficiently at a well site or other location are provided. Present embodiments are directed to a rotary clamshell gate actuation system and method, where the gate is separate from the one or more actuators used to open/close the gate. The disclosed system may include a portable bulk material container with a clamshell gate for easily dispensing material from the container. The system also includes a support structure equipped with one or more rotary actuators used to actuate the clamshell gate of the container between a closed and open position when the container is positioned on the support structure. The disclosed clamshell gate actuation system is easy to operate, low cost to manufacture, and reliable even when the portable container is not precisely aligned on the support structure.

A reusable proppant pod provides a containerized system for transport of oilfield proppant to a well location, and facilitates rapid discharge of the proppant in support of hydraulic fracturing operation. The proppant pod has a cylindrical sidewall, a top, and a frustoconical bottom that tapers towards a discharge gate. An external frame may be provided in rectilinear form to stabilize the proppant pod for road transport and to facilitate storage-stacking of a plurality of such proppant pods, one atop the other. The proppant pod is provided with fork lift tubes extending through the cylindrical sidewall. The proppant pod may have a solid top, in which case the proppant pod is inverted for filling operations that introduce proppant into the proppant pod through the discharge gate. A vent assembly is provided to facilitate entry of air during proppant discharge operations, where the vent assembly provides also a seal against proppant leakage during the inverted fill operation.
