Abstract
A method and apparatus for separating components of wet cement. A reclaim gate includes a tumbler flange with a tumbler flange opening. A strainer having strainer openings passes sand, rinse water, and cement slurry while blocking cement aggregates. A fixed plate entraps the strainer in place. The fixed plate has a reclaim aperture aligned with the screen. A rotating turn plate having a matching reclaim aperture is adjacent the fixed plate. A gate actuator retains the turn plate adjacent the fixed plate such that the turn plate can turn to selectively align the turn plate aperture with the fixed plate aperture. In use the aggregates are blocked by the screen, the sand passes through and is filtered; the slurry passes through and is collected and settled. The aggregates, sand, and rinse water can be recovered.
Claims13
A reclaim gate comprising:
- a tumbler flange having a tumbler flange opening;
- a strainer adjacent said tumbler flange, said strainer having a central strainer pivot aperture and a screen having strainer openings;
- a fixed plate entrapping said strainer adjacent said tumbler flange, said fixed plate rigidly attached to said tumbler flange by threaded fasteners, said fixed plate having a central fixed plate aperture and a fixed plate reclaim aperture aligned with said screen;
- a rotating turn plate having a central turn plate aperture and a turn plate reclaim aperture;
- and,
- a gate actuator that passes through said central turn plate aperture, through said central fixed plate aperture and into said central strainer pivot aperture;
- wherein said gate actuator retains said turn plate adjacent said fixed plate such that said turn plate can turn to selectively align said central turn plate aperture with said central fixed plate aperture;
- wherein said tumbler flange is welded to a truck.
A ready mix cement truck comprising:
- a rotating tumbler on a truck frame, said rotating tumbler having a tumbler aperture;
- a tumbler flange having a tumbler flange opening aligned with said tumbler aperture, said tumbler flange being permanently attached to said tumbler;
- a strainer adjacent said tumbler flange aperture, said strainer having a central strainer pivot aperture and a screen having strainer openings;
- a fixed plate entrapping said strainer adjacent said tumbler flange, said fixed plate rigidly attached to said tumbler flange by threaded fasteners, said fixed plate having a central fixed plate aperture and a fixed plate reclaim aperture aligned with said screen;
- a rotating turn plate having a central turn plate aperture and a turn plate reclaim aperture;
- and,
- a gate actuator that passes through said central turn plate aperture, through said central fixed plate aperture and into said central strainer pivot aperture;
- wherein said gate actuator retains said turn plate adjacent said fixed plate such that said turn plate can turn to selectively align said central turn plate aperture with said central fixed plate aperture.
