Patent number: 10618744Abstract: A system for distributing a fracking proppant at a well site using a support frame to position a series of storage containers above a conveyor. The support frame receives a plurality of storage container and aligns the storage containers with hoppers formed on the conveyor. The support frame can include outriggers that extend to increase the stability and the amount of supported weight. The support frame includes a series of cross supports that extend across the conveyor belts to support the storage containers. The cross supports can include load cells to monitor the weight of the storage containers and stored proppant. The width of the cross supports can be adjusted and the support frame can include an extension frame to expand the width of the support frame. A control panel is included to display the status of the containers (full/empty/partially full) and control and monitoring the discharge rate of the plurality of containers.Type: GrantFiled: September 6, 2017Date of Patent: April 14, 2020Assignee: Proppant Express Solutions, LLCInventors: Kenneth W. Eiden, III, Timothy Stefan, Mark D'Agostino, Scott D'Agostino, Clint Lohman, Marc Kevin Fisher

Patent number: 10118529Abstract: An intermodal container for transporting frac proppant, such as frac sand, and/or other types of granular material is disclosed. The intermodal container is designed to receive frac sand from a quarry or other frac sand supply source. Once the container is filled with material, the container is loaded onto a transportation device and transported to a well site. Once received at the well site, the containers can be stacked and the frac sand stored until needed. Once the frac sand is needed, the containers are placed on a base unit and the container discharges its contents onto a conveying system formed as part of the base unit. The conveying system directs the frac sand to a blending location. The empty intermodal containers can be removed from the base unit and loaded onto a transportation device to be refilled at a mine site.Type: GrantFiled: June 14, 2017Date of Patent: November 6, 2018Assignee: Proppant Express Solutions, LLCInventors: Kenneth W. Eiden, III, Brian Andrew Hunter, Mathew Carley, Timothy Stefan, Mark D'Agostino, Scott D'Agostino

Publication number: 20150086307Abstract: Described herein is an improved container for storing, shipping, and dispensing proppant materials used in hydraulic fracturing operations. The container systems incorporate stretchable hopper structures in the container. The hopper expands and contracts responsive to the amount of proppant material held in the container. When the container is filled with a sufficient amount of proppant, the hopper stretches to expand the storage volume. When the sufficient amount of proppant material is dispensed from the container, the hopper contracts to lift and dispense the container contents.Type: ApplicationFiled: September 24, 2014Publication date: March 26, 2015Inventor: Timothy Stefan
