Abstract
A readily assembled and disassembled silo for the bulk storage of granular materials consists of a rigid, generally rectangular metal frame that supports a grid of interconnected horizontal and vertical bands of flexible webbing material extending between vertical posts and horizontal upper and lower bars. A flexible bag of woven polyolefin is supported within the metal frame and webbing grid. This bag has a filling tube near its top, discharge tubes near its bottom and a screened ventilator opening.
Claims11
A flexible bag silo for bulk storage of granular material, comprising
- (a) a generally rectangular metal frame defining an open-bottomed peripheral framework adapted to be free standing on a firm horizontal floor;
- (b) a grid of interconnected bands of flexible material extending between parts of said frame;
- and
- (c) a flexible bag confined by said frame and said grid while resting on the floor, said bag having at least one filling tube near the top thereof, at least one discharge tube at a side of the bag near the bottom thereof to enable discharging of the bag while so resting on the floor, and a ventilator opening near the top thereof;
- (d) wherein said frame is formed of vertical posts, horizontal upper and lower bars and means for connecting said posts and bars, said means being capable of being readily assembled and disassembled to permit said posts and bars to be placed in a storage condition, said bands of flexible material extending horizontally and vertically between said posts and bars respectively, said bands being collapsible to facilitate disassembly to said storage condition;
- and
- (e) wherein said horizontal upper bars form a peripheral structure defining a horizontal plane, a series of suspension means serving to support the upper periphery of said bag from said peripheral structure.
A flexible bag silo for bulk storage of granular material, comprising
- (a) a generally rectangular metal frame formed of vertical posts, horizontal upper and lower bars and means for connecting said posts and bars to define an open-bottomed peripheral framework adapted to be free standing on a firm horizontal floor, said means being capable of being readily assembled and disassembled to permit said posts and bars to be placed in a storage condition;
- (b) a grid of interconnected bands of flexible material extending between the posts and bars of said frame, said bands being collapsible to facilitate disassembly to said storage condition;
- (c) a flexible bag confined by said frame and said grid while resting on said floor, said bag having at least one filling tube near the top thereof, at least one discharge tube at a side of the bag near the bottom thereof to enable discharging of the bag while so resting on the floor, and a ventilator opening near the top thereof;
- and
- (d) pneumatic means for blowing granular material into said bag through a said filling tube and for withdrawing such material from the bag through a said discharge tube.
