Abstract
A dry granular material transfer system and method for transfer of granular material such as sand in a dry state through a hose using pressurized air. On a base platform, a conveyor subsystem moves granular material placed on a lower portion to a higher portion while separating clumped material and allowing rocks and debris to fall away, spreading the granular material in a thin layer for ejection at the highest level. A containment subsystem receives granular material and contains the downward fall of material. A portioning subsystem has a turntable with blow-through chambers which receive granular material and move into line with an air inflow tube and air-material outflow tube, and the air-material mixture is blown through the air-material outflow tube and through a transfer hose.
Claims19
A dry granular material transfer system comprising:
- (i) a base platform;
- (ii) a conveyor subsystem mounted upon said base platform, having an angular orientation from low to high, adapted to move granular material placed on a lower portion to a higher portion, while separating clumped material and allowing rocks and debris to fall away, and to spread the granular material in a thin layer for ejection at the highest level;
- (iii) a containment subsystem mounted upon said base platform, adapted to receive and contain the granular material ejected from said conveyor subsystem;
- (iv) a portioning subsystem mounted upon said base platform, having a turntable with a plurality of blow-through chambers, and having an air inflow tube and air-material outflow tube, adapted to receive the granular material from said containment subsystem into said blow-through chambers and to rotate said blow-through chambers into alignment with said air inflow tube and air-material outflow tube, to blow the granular material through said blow-through chambers, said air-material outflow tube, and an attached transfer hose;
- (v) an air subsystem adapted to supply compressed air;
- and
- (vi) a control subsystem adapted to control operation of said conveyor subsystem, said portioning subsystem, and said air subsystem.
A dry granular material transfer method comprising:
- (i) providing a dry granular material transfer system comprising:
- (a) a base platform;
- (b) a conveyor subsystem mounted upon said base platform, having an angular orientation from low to high, adapted to move granular material placed on a lower portion to a higher portion, while separating clumped material and allowing rocks and debris to fall away, and to spread the granular material in a thin layer for ejection at the highest level;
- (c) a containment subsystem mounted upon said base platform, adapted to receive and contain the granular material ejected from said conveyor subsystem;
- (d) a portioning subsystem mounted upon said base platform, having a turntable with a plurality of blow-through chambers, and having an air inflow tube and air-material outflow tube, adapted to receive the granular material from said containment subsystem into said blow-through chambers and to rotate said blow-through chambers into alignment with said air inflow tube and air-material outflow tube, to blow the granular material through said blow-through chambers, said air-material outflow tube, and an attached transfer hose;
- (e) an air subsystem adapted to supply compressed air;
- and
- (f) a control subsystem adapted to control operation of said conveyor subsystem, said portioning subsystem, and said air subsystem;
- (ii) activating said dry granular material transfer system;
- (iii) supplying the granular material on the lower portion of said conveyor subsystem;
- and
- (iv) transferring and distributing the granular material through said transfer hose.
