Abstract
The invention relates to a soaking system for solids. The system includes stacked tanks each of which has a conical bottom. The tanks are connected through perforated valves through which the solids move from the top and water is fed from the bottom. The solids are soaked in a counterflowing water. In one embodiment, two or more similar units are stacked one upon the other for more efficient operation.
Claims14
A counterflow soaking system for soaking solids in a liquid in a substantially continuous manner comprising:
- more than one similar containers stacked one upon the other for holding the solids therein;
- each container comprising;
- an inlet at the top portion thereof for feeding the solid therein;
- an outlet at the bottom portion thereof for extracting the soaked solids therefrom;
- a liquid inlet at the bottom portion thereof for feeding the liquid into the container under pressure;
- and
- a liquid outlet at the top portion thereof for removing the liquid therefrom;
- and
- a perforated valve provided between two adjacent containers and connecting the outlet of an upper container with the inlet of the container immediately below it.
A method of soaking solids in a liquid in a substantially continuous manner, using more than one similar container stacked one upon the other, comprising steps of;
- feeding solids to be soaked into the top container from an inlet located at the top portion thereof;
- feeding liquid under pressure into the bottom container from the liquid inlet located at the bottom portion thereof;
- passing the liquid from the bottom container to the container immediately above it and so on towards the top container;
- removing the liquid from a liquid outlet located at the top portion of the top container so that the liquid flows upwardly from the bottom container to the top container;
- allowing the solids to fall from a container to the container immediately below it, and
- extracting soaked solids from the bottom container from an outlet located at the bottom portion thereof.
