Abstract

A processing system for a slurry material. The system has a vibratory screen disposed atop an open-topped tank. A travel path for a vehicle is disposed directly above the screen and the tank. Slurry material dumped from the vehicle onto the screen is separated at the screen into a particulate-rich stream and a fluid-rich stream. The fluid-rich stream may be pumped to a cleaner so that it may be stored and re-used as drilling fluid. The screen may be a conveyor which removes the particulate-rich stream from above the tank.

First claim

The invention claimed is:

1. A dumping station for receiving material from a transport vehicle, the dumping station comprising:
a tank for receiving material discharged from a transport vehicle, the tank defined by a first dimension and a second dimension substantially perpendicular to the first dimension, wherein the first dimension is greater than the second dimension;
spaced apart first and second tracks for supporting transport vehicles, disposed in a direction substantially parallel to the second dimension; and
a screen disposed above the tank and configured to receive a slurry material flowpath from the transport vehicle and to separate the slurry material flowpath into a particulate-rich flowpath and a recovered fluid-rich flowpath.

2. The dumping station of claim 1 further comprising a conveyor extending proximate the tank to remove material from the dumping station.

3. The dumping station of claim 1 wherein the screen comprises an endless belt disposed between rotating hubs.

4. The dumping station of claim 3 in which the screen is configured to carry particulates along a portion of the particulate-rich flowpath.

5. The dumping station of claim 4 in which the portion of the particulate-rich flow path provided by the screen is substantially parallel to the second dimension.

6. A system comprising:
a first ramp;
a second ramp;
the dumping station of claim 5 , wherein the first ramp, second ramp, and dumping station define a vehicle travel path that is orthogonal to the first dimension.

7. A system comprising:
a first ramp;
a second ramp;
the dumping station of claim 1 , wherein the first ramp, second ramp, and dumping station define a vehicle travel path that is orthogonal to the first dimension.

8. The dumping station of claim 1 further comprising a shield disposed above the tank.

9. The dumping station of claim 8 in which the shield is configured for positioning above the tank between the first and second tracks.
