Modular bulk material storage structure

A modular bulk materials storage structure (100) comprising:

• a set of lower modules (200) comprising:
• a first lower module (210) comprising a first sloped surface (212), a second sloped surface (214), adjacent to the first sloped surface (212), and a third sloped surface (216), adjacent to the first sloped surface (212) and positioned opposite to the second sloped surface (214), the first sloped surface (212), second sloped surface (214), and third sloped surface (216) joined to form a first partial funnel;
• and
• a second lower module (230) comprising a fourth sloped surface (232), a fifth sloped surface (234), adjacent to the fourth sloped surface (232), and a sixth sloped surface (236), adjacent to the fourth sloped surface (232) and positioned opposite to the fifth sloped surface (234), the fourth sloped surface (232), fifth sloped surface (234), and sixth sloped surface (236) joined to form a second partial funnel,
• wherein the first lower module (210) and the second lower module (230) are configured to combine to define at least a portion of a lower structural layer (202), and wherein the first partial funnel and the second partial funnel define at least a portion of a whole funnel (204) within the lower structural layer (202);
• and
• at least one set of middle modules (300) comprising:
• a first middle module (310) comprising a first wall (312), a second wall (314), adjacent to the first wall (312), and a third wall (316), adjacent to the first wall (312) and positioned parallel and opposite to the second wall (314);
• and
• a second middle module (330) comprising a fourth wall (332), a fifth wall (334), adjacent to the fourth wall (332), and a sixth wall (336), adjacent to the fourth wall (332) and positioned parallel and opposite to the fifth wall (334),
• wherein the first middle module (310) and the second middle module (330) are configured to combine to define at least a portion (302) of a middle structural layer (802), and wherein the first wall (312), the second wall (314), the third wall (316), the fourth wall (332), the fifth wall (334), and the sixth wall (334) define at least a portion of a rectangular enclosure (304) within the portion (302) of the middle structural layer (802),
• wherein the lower structural layer (202) and the middle structural layer (802) are configured to join together to form at least a portion of a storage enclosure (810) capable of storing and funneling bulk materials.
