Abstract
A slurry recovery sump apparatus is formed from a substantially vertical sidewall and a substantially circular horizontal cross-section and includes a bottom. A support extends diametrically across the sump and above the sump, a material input is mounted between the sidewall and the vertical axis of the sump and is attached to the support, a slurry removal apparatus is mounted to the support between the sidewall and the sump vertical axis on the opposite side from the material input. Apparatus is provided for rotating the sump support around the vertical axis and additional apparatus is provided for moving the sump removal apparatus in a prescribed manner to empty the material being deposited into the sump by the material input.
Claims6
A slurry recovery sump apparatus comprising:
- (a) a substantially vertical sidewall and a substantially circular horizontal cross-section defining a vertical axis;
- (b) a bottom means;
- (c) support means extending diametrically across said sump and above said sump;
- (d) material input means mounted between the sidewall and the vertical axis of said sump and mounted to and distributed along said support means;
- (e) pipe communication means connected from a remote location to said vertical axis through a pivotal coupler to said material input means;
- (f) slurry removal means having an output, said slurry removal means mounted to said support between said sidewall and said sump vertical axis and mounted to said support means on the opposite side from said material input means;
- (g) slurry transportation pipe means connected from said slurry removal means output through a pivotal coupler to a remote location;
- and
- (h) means for rotating said support means about the vertical axis of said sump.
