Proppant container system for hydraulic fracturing operations
A newly granted patent (Publication Number: US11867044B2) discloses a proppant dispensing system designed to efficiently handle proppant materials used in hydraulic fracturing operations. The system comprises a plurality of proppant container systems, each consisting of a proppant container with a frame supporting a reservoir for the proppant. The system includes a cradle for retaining the container, a support frame allowing tipping motion for proppant flow, tipping mechanisms for controlled tipping, a central hopper for receiving proppant, a conveyor belt system, a blending unit, and an elevator conveyor with a metering system for proppant transfer.
The patent details various aspects of the proppant dispensing system, including the design of the proppant containers with solid bottoms and cylindrical sidewalls, the structure of the cradles for tipping motion, the use of tipping mechanisms with actuators for controlled tipping, and additional features like insulation for the containers. The system also incorporates means for determining proppant discharge, such as load cells and empirical correlations based on input parameters like time and moisture content. Furthermore, the system includes a surge hopper for proppant transfer and can be configured with multiple container systems and conveyor belt orientations for enhanced efficiency in handling proppant materials during hydraulic fracturing operations.
