ABSTRACT:
A device and method for separating particulate material from earth drilling fluids is disclosed, wherein the earth drilling fluids containing such particulate material is introduced into a container. A major portion of the particulate material separates out of the earth drilling fluid, and the fluid then passes over a baffle and through a screen, with the movement past the screen being such, combined with the screen orientation, to provide a screen which is somewhat self-cleaning in nature. The screen is periodically scraped by carrying members, and is urged against the carrying members so that the initial contact of the carrying members with the screen causes vibrations which improve the self-cleaning characteristics of the screen.
The particulate material which settles out of the drilling fluid, and the particulate material which is screened out of the drilling fluid, is collected in the bottom of the container and is removed therefrom by the carrying members up an inclined wall to a discharge point.
