A closure device for a bulk material system is provided, specifically for regulating a flow of heat transfer particles. The closure device includes a bulk material guide which has a first opening for connection to the bulk material system and a second opening for the discharge of a bulk material guided by the bulk material system, and a closure blade which is rotatably mounted about an axis of rotation. The closure blade, in a first rotational position, closes the second opening and, in a second rotational position, at least partially uncovers the second opening. The closure blade is mounted in such a manner to reduce jamming of the closure device in operation.

Methods for handling bulk material in a manner that reduces dust, noise, and emissions are provided. The presently disclosed techniques use portable containers to transfer bulk material from a transportation unit to a blender inlet. The containers may be carried to the location on the transportation unit, where a hoisting mechanism is used to remove the container from the transportation unit and place it in a desired location. When bulk material is needed at the blender inlet, the hoisting mechanism may position the container of bulk material onto an elevated support structure. Once on the support structure, the container may be opened to release bulk material to a gravity feed outlet, which routes the bulk material from the container directly into the blender inlet. The disclosed containerized bulk material transfer system and method allows for reduced dust, noise, and emissions on location.

In accordance with presently disclosed embodiments, systems and methods for efficiently managing bulk material and dry additives to be mixed with bulk material in a blender are provided. The disclosed systems include a modular portable container that can be used to hold multiple types of dry flowable material for transportation about a work site. The different types of dry materials can be selectively released from the modular container for mixing with liquid and bulk material in a blender. The modular container generally includes a base structure that supports a number of individual, separable, and fully enclosed compartments. The compartments may each hold a different type of dry material, and the compartments may be arranged onto the base structure adjacent one another and removably secured to the base structure so that the compartments can be transported as a single unit about the work site.

A cover assembly for a container including a frame having a rail, a cover coupled to the frame, a first opening mechanism including a first pivot and a first slide housing, and a second opening mechanism including a second pivot and a second slide housing, the rail of the frame being selectively and slidingly receivable in the first and second slide housings. The cover and frame are movable between three positions, a closed position, a first open position wherein the rail is partially disposed in the first slide housing and is disengaged from the second slide housing, and the frame, cover and first slide housing are rotated about the first pivot, and a second open position wherein the rail is partially disposed in the second slide housing and is disengaged from the first slide housing, and the frame, cover and second slide housing are rotated about the second pivot.

The present invention relates to a container for holding bulk material, having a closable inlet for the bulk material in the upper closure of the container, a cross-sectional geometry narrowing in the outlet direction for the bulk material, an outlet tube for the bulk material arranged subsequently in the outlet direction, a first reversible mechanical closure device (A), which is arranged in the transition region from the container body to the outlet tube or in the outlet tube itself and, by opening, releases the bulk material from the interior of the container, and a second closure device (B) which reversibly closes the mouth of the outlet tube, the second closure device being a cover which is pressed flush onto the mouth of the outlet tube by means of a closure device, there being a seal which seals the outlet tube in a gas- and liquid-tight fashion from the external environment at least on the contact surface of the cover with the mouth degree of the outlet tube, wherein the cover is screwed onto or is pressed with a clamping ring or a bayonet closure onto the mouth of the outlet tube.

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.
