Modified Cargo Container for Delivery of Proppant to a Frac Site

摘要

A cargo container is modified to carry a fracing proppant such as sand from a quarry or source to the frac site. Openings are cut in the top and bottom of a cargo container and hydraulically operated sliding doors are placed there under. A hopper module with the walls being inclined to approximately the angle of repose for the proppant is installed inside the cargo container. The hopper module is sealed inside the cargo container so that a proppant enters through the top opening at the quarry and flows out through the bottom opening at the fracing site.

1. A modified cargo container for carrying a fracing proppant such as sand from a quarry or source to a frac site, the modified cargo container comprising:
a cargo container with cargo doors on one end thereof; a top opening and a bottom opening being cut in said cargo container; a hopper module inserted into said cargo container through said cargo doors, said hopper module having a frame there under to support walls of said hopper module at an angle near the angle of repose of said proppant so that after said hopper module in said cargo container is loaded through said top opening with said proppant, essentially all said proppant may subsequently flow out said hopper module and said cargo container via said lower opening; a top sliding door being located at said top opening; a bottom sliding door being located at said bottom opening; operating devices for actuating said top sliding door to open or close said top opening at selected times and actuating said bottom sliding door to open or close said bottom opening at selected times.
