Fracture sand silo system and methods of deployment and retraction of same
View Patent ↗The present invention is directed to novel transportable silo systems for storage of materials. The invention relates to self-erecting silo storage systems for use in the oil and natural gas mining and drilling industries. The silo storage systems of embodiments of the instant invention are uniquely designed to improve storage capabilities and mobility while at the same time reducing space requirements at well sites.
1. A storage system comprising:
(a) a base platform having a first and a second silo positioned vertically thereon and attached thereto, wherein each silo includes a top end and a bottom exit;
(b) a first shuttle conveyor that receives a first material released from the bottom exit of the first silo and a second shuttle conveyor that receives a second material from the bottom exit of the second silo, wherein the first and second shuttle conveyors are positioned between the platform and the first and second silos respectively;
(c) a main conveyor system oriented to receive the first and second materials from the first and second shuttle conveyors and to deliver the first and second materials into a container;
(d) a monitoring device that dynamically monitors a level, mass or amount of material contained in the container; and
(e) a control system configured to dynamically regulate the speed of the first and second shuttle conveyors to provide a calculated amount of released first and second material onto the main conveyor system and into the container, wherein the control system matches the delivery rate of the first and second materials into the container with the exit rate of material from the container to maintain a constant level of material in the container based on the level, mass or amount of material contained in the container as communicated by the monitoring device.
2. The storage system of claim 1 , wherein the shuttle conveyor is mounted on rollers.
3. The storage system of claim 1 , wherein each silo has a silo monitoring device such that the level, mass or amount of material in each silos is detected.
4. The storage system of claim 1 , wherein the control system includes a control panel where an operator at a single location controls the rate of release of material from the first and second silos, the speed of the first and second shuttle conveyors receiving the released material from first and second silos, and the speed of the main belt conveyor system discharging the material into the container.
5. The storage system of claim 3 , wherein said silo monitoring device is a pulsed radar.
6. The storage system of claim 3 , wherein the speed of each shuttle conveyor is regulatable based on the level, mass or amount of material detected by said silo monitoring device in the silo releasing its material onto that shuttle conveyor.
7. The storage system of claim 1 , wherein the monitoring device that monitors the level, mass or amount of material in the container is a pulsed radar.
