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 including a proppant container with a reservoir for storing proppant material. The containers are supported by a cradle that allows for easy removal and tipping to facilitate the flow of proppant. A support frame with tipping mechanisms enables controlled tipping motion of the cradle to discharge proppant into a central hopper, which then feeds into a conveyor belt system, blending unit, and elevator conveyor for further processing.
The patent details various features of the proppant dispensing system, including the design of the proppant containers with solid bottoms and cylindrical sidewalls, insulated surfaces, and specific dimensions to hold varying amounts of proppant material. The system also incorporates load cells for monitoring proppant discharge, empirical correlations for determining discharge amounts, and surge hoppers for efficient material handling. Additionally, the system can be configured with multiple container systems oriented at right angles to each other, forming a scissortail arrangement to optimize material flow. Each tipping mechanism is equipped with a hydraulically actuated ram for precise control over the discharge process, ensuring accurate and efficient handling of proppant materials in hydraulic fracturing applications.
