Abstract
A wet-blast machine (1) with a closed-cycle re-use system (2) incorporates apparatus (3) for conveying loose particulate (abrasive) wet-blast material (4) present in a body of water (5). The apparatus (3) comprises a longitudinally extending trough (6), for containing the water (5) and particulate material (4), a support structure (7) movable in a reciprocating manner within the trough (6), and a row of longitudinally spaced flap members (8) attached to and depending from the support structure (7). When the support structure (7) is reciprocated, wave motions are created in the water (5), which move the loose particulate material (4) in a predetermined direction along the trough (6), namely toward a collection point provided by a chute (10).
Claims19
Apparatus for conveying loose particulate material present in a body of liquid, said apparatus comprising a longitudinally extending trough, for containing the body of liquid and the particulate material, a support structure movable in a reciprocating manner within the trough, and a row of longitudinally spaced flap members attached to and depending from the support structure, whereby, with the liquid in the trough, when the support structure is reciprocated, wave motions are created in the liquid which move the loose particulate material along the trough.
A method of conveying loose particulate material present in a body of liquid along an open trough, comprising the steps of (a) creating wave motions in said body of liquid and (b) moving said material by said wave motions in a predetermined direction along the open trough.
Apparatus for conveying loose particulate material present in a body of liquid, the apparatus comprising a longitudinally extending trough, for containing the liquid and the particulate material, a support structure comprising a pair of laterally spaced longitudinal members interconnected by laterally extending cross-members and movable in a reciprocating manner within the trough, and a row of longitudinally spaced, flexible flap members extending across substantially a whole width of the trough, and in close proximity to a bottom thereof, and demountably attached to and depending from the support structure, whereby, with the liquid in the trough, when the support structure is reciprocated, wave motions are created in the liquid which move the loose particulate material along the trough.
