Abstract
An automatic self-cleaning liquid clarification system wherein suspended solids are removed from a contaminated liquid. A hollow drum carrying a plurality of brushing elements mounted on its outer periphery scrubs a strainer or screen and elevates the solid contaminants separated by the screen into a pitched auger conveyor which removes additional liquid from the solids materials which are then conveyed in a semi-dry or damp state for discharge.
Claims6
A liquid solid separation microstrainer apparatus for removing suspended solids material from a contaminated liquid passed into the apparatus comprising a rotatable drum
- straining means for separating solid material from a liquid, passing the liquid therethrough and retaining the solids material on the surface thereof,
- said straining means positioned adjacent to the inlet for contaminated liquid and extending downwardly therefrom to a lowermost point and then upwardly to a discharge position above said lowermost point,
- brushing means carried by said rotatable drum for conveying the solids materials from the surface of said straining means positioned adjacent the surface thereof and in engagement therewith,
- conveyor means for removing and draining solids material passed thereto positioned adjacent the discharge position of said strainer means to receive solids material conveyed thereto by said brushing means,
- said conveyor means positioned to forward solids material passed thereto and to drain liquid therefrom, and
- means for discharging solids material from said conveyor means.
The method of liquid/solid separation in a microstrainer comprising
- passing contaminated liquid bearing suspended solids material therein over a separating medium,
- gravitationally straining contaminated liquid through teh separating medium removing the suspended solids material therefrom and passing the clarified liquid therethrough,
- brushing the suspended contaminants from the surface of said separating medium and conveying sad contaminants upwardly to permit gravitational separation of liquid contained therewith by brushing means carried by a rotatable drum of the microstrainer, and
- conveying said solids material for disposal.
