A collapsible storage system for flowable material, for example granular material, includes a base frame and an upper frame which is movable between a collapsed position and a working position spaced above the collapsed position. A plurality of storage silos are supported in a row, each including a hopper discharge cone on the base frame and a collapsible tubular wall assembly connected between the discharge cone and the upper frame. Redundant loading conveyors are provided in communication with the silos across the upper frame for loading and redundant unloading conveyors are provided in communication with the silos across the base frame.

A portable storage bin includes a base frame on the ground and a bin support frame operable relative to the base frame between a working position and a transport position which is reduced in height relative to the working position, and a storage envelope supported on the bin support frame to define a storage chamber for storing particulate material therein in the working position of the bin support frame in which the storage envelope is collapsible with the bin support frame from the working position to the transport position. The bin support frame has an upper frame portion from which the storage envelope is suspended in the working position and a central support post which is extendable in height between the upper frame portion and the base frame for raising the envelope from the transport position to the working position.

A flexible portable silo for storing grains and bulk materials, comprising a flexible cylindrical wall and a flexible conical roof made of a flexible, foldable, tension bearing sheet membrane, and a single pressure bearing post, with outriggers installed at the top of the post. The flexible cylindrical wall and conical roof are then draped over the outriggers and post and filled with grain or other bulk material.

A fan assembly attaches to and may be used with an existing fan of a storage container. The fan assembly includes an exhaust fan, a mounting assembly for operatively mounting the exhaust fan to the existing fan of the storage container, and a sealing member operatively positioned between the exhaust fan and the existing fan to provide a seal to direct movement of air streams created, in part, by the exhaust fan. During operation of the exhaust fan, the exhaust fan pulls contaminated air and airborne matter from within the storage container through the existing fan and an existing duct in order to exhaust the contaminated air and airborne matter from the storage container.

In which a plurality of plates (1), made of injected recycled polymer material, joined together by coupling fittings (2) and secured by retaining devices (3) form peripheral walls (4).) Fitted on a base (5) which reproduces the floor plan of the structure being assembled.

A bin sweep auger unplugging system for unplugging a central unloading sump in a storage bin. The bin sweep auger unplugging system generally includes an auger having a driven shaft with auger flighting, a drive unit having a drive shaft, and a clutch connected between the drive shaft and the driven shaft. The clutch selectively transfers the rotation of the drive shaft to the driven shaft of the auger. The drive shaft includes a clump breakup component that breaks up the clump of granular material above the unloading sump when the drive shaft is rotated. The clutch is disengaged when breaking up a clump of granular material to prevent the rotation of the auger.

A method for constructing a cylindrical tank which has a metallic inner tank and a concrete outer tank includes a step of building up a PC wall in an outer circumferential edge portion of a base plate, a step of assembling an outer tank roof on the base plate other than the outer circumferential edge portion of the base plate, a step of lifting the outer tank roof which is on the base plate using a jack-up unit while the PC wall is being built up and then holding the outer tank roof on the PC wall, and a step of assembling the inner tank independently of the outer tank roof in a space under the outer tank roof which is created due to the lifting.

An inflatable storage container (100) for liquids or other bulk materials comprises a first portion (5) that defines abase and a second portion (4) that defines a perimeter wall that extends from a perimeter of the base, the two portions together forming an inflatable chamber. The perimeter wall comprises at least one layer of cloth that has been impregnated with a water-settable material. In use, after or when the inflatable chamber is inflated and the water-settable material is set, the first portion and second portion define a storage chamber for a liquid or other bulk material. A method of deploying a deployable storage container is also provided. A combination of a container and an inflation system suitable for inflating the container to form its final deployed shape prior to the water-settable material having set is further provided.
