Abstract
An apparatus for mixing and pumping manure slurry from a manure pit comprises a pump unit having first and second mixing rotors and a pumping rotor. In operation, the first mixing rotor draws solids downwardly towards the pump unit while the second mixing rotor redirect a portion of the solids drawn by the first mixing rotor away from the pump unit, thereby allowing to control the ration of solid contents in the slurry pumped by the pumping rotor. A non-diverted flow distribution arrangement is also provided for selectively connecting the pump outlet in straight-through flow connection with either a drainage pipe or a re-circulation pipe.
Claims10
An apparatus for mixing and pumping manure slurry from a manure pit, the apparatus comprising:
- a pump unit adapted to be positioned within the manure pit, the pump unit having top, bottom and lateral faces;
- a first bladed rotor projecting from said top face of the pump unit for creating a downward flow of slurry and drawing solids downwardly against the pump unit;
- a second bladed rotor provided on the bottom face of the pump unit for drawing liquids upwardly from a bottom portion of the manure pit;
- and a third bladed rotor projecting from one of the lateral faces of the pump unit between the top and bottom faces thereof for redirecting a portion of the flow of solids drawn by the first bladed rotor away from the pump unit.
