A slurry handling and disposal system is provided for waste slurry and particulates. The system includes a waste bin provided with support structures for retaining a flexible removable filter element with a filter element supported above a floor of the waste bin. The particulate matter component of a volume of the waste slurry and particulates deposited in the filter element is retained in said filter element while the liquid component of the waste slurry and particulates are collected in a base portion of the waste bin.
1. A waste slurry handling and disposal system for use with a mobile ready-mix concrete vehicle, the system comprising:
a waste bin which is moveable with a height adapted to receive waste slurry from said mobile ready-mix concrete vehicle, the waste bin having a base, sidewalls and a front end adjacent said mobile ready-mix concrete vehicle and a back end remote from said mobile ready-mix concrete vehicle, the back end having a chevron shape oriented on a longitudinal axis, wherein the chevron shape has an apex which is pointed away from the front end, the waste bin having at least one baffle structure arranged on the longitudinal axis and spaced along the base extending between the sidewalls of the waste bin, the at least one baffle structure having a chevron shape generally conforming to the chevron shape on the back end, each of the at least one baffle structure having at least one fluid passing aperture at a lower edge of the at least one baffle structure adjacent to a side wall of the waste bin; and a liquid discharge port located near the back end of the waste bin.
2. The system of claim 1 wherein the waste bin has more than one at least one baffle structure.
3. The system of claim 1 further comprising at least two lifting fixtures mounted on an outside surface of the sidewalls adjacent the front and back ends.
4. The system of claim 1 wherein the sidewalls have inward slopes.
5. The system of claim 1 further comprising a latching lid.
6. The system of claim 1 further comprising a tilt support under the front end of the waste bin so that a floor is declining toward the back end.
7. The system of claim 6 further comprising a plurality of leveling jacks affixed to the waste bin.
8. The system of claim 1 further comprising a pump for transfer of liquid having an inlet which is removably coupled to the liquid discharge port.
9. The system of claim 1 wherein the at least one fluid passing aperture of each of the at least one baffle structure is located at an intersection of the lower edge of the respective at least one baffle structure and one of the side walls.
10. A waste slurry handling and disposal system for use with a mobile ready-mix concrete vehicle, the system comprising:
a waste bin which is moveable with a height adapted to receive waste slurry from said mobile ready-mix concrete vehicle, the waste bin having a lower base, sidewalls and a front end adjacent said mobile ready-mix concrete vehicle and a back end remote from said mobile ready-mix concrete vehicle, the back end having a chevron shape oriented on a longitudinal axis, wherein the chevron shape has an apex which is pointed away from the front end, the waste bin having at least one baffle structure configured to restrict excessive movement of liquid during movement of the waste bin, wherein the at least one baffle structure is arranged on the longitudinal axis and spaced along the lower base and between the sidewalls of the waste bin, the at least one baffle structure having a chevron shape conforming to the chevron shape on the waste bin, each of the at least one baffle structure having fluid passing apertures at lower edges of the at least one baffle structure adjacent to a side walls of the waste bin;
a liquid discharge port located near the back end of the waste bin;
at least two lifting fixtures mounted on an outside surface of the sidewalls adjacent the front and back ends; and
a tilt support under the front end of the bin so that the floor is declining toward the back end.
11. The system of claim 10 wherein the waste bin has more than one at least one baffle structure.
12. The system of claim 10 wherein the sidewalls have inward slopes.
13. The system of claim 10 further comprising a latching lid.
14. The system of claim 10 further comprising a plurality of leveling jacks affixed to the waste bin.
15. The system of claim 10 further comprising a pump for transfer of liquid having an inlet which is removably coupled to the liquid discharge port.
16. A method of handling and disposal for waste slurry and particulates, said method comprising:
moving a waste bin into position under a mobile ready-mix concrete vehicle, the waste bin having a base, sidewalls and a front end adjacent said mobile ready-mix concrete vehicle and a back end remote from said mobile ready-mix concrete vehicle, the back end having a chevron shape oriented on a longitudinal axis wherein the chevron shape has an apex which is pointed away from the front end, the waste bin having at least one baffle structure arranged on the longitudinal axis and spaced along the base extending between the sidewalls of the waste bin, the at least one baffle structure having a chevron shape generally conforming to the chevron shape on the back end, each of the at least one baffle structure having at least one fluid passing aperture at a lower edge of the at least one baffle structure adjacent to a side wall of the waste bin;
directing waste slurry into the waste bin;
allowing liquid and particles to drain through the at least one fluid passing apertures;
lifting the waste bin and transferring the waste bin to a waste handling bin for disposal; and
discharging liquid through a port located at the back end of the waste bin.
