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.
Claims15
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.
An apparatus for mixing and pumping manure slurry from a manure pit, comprising a pump unit adapted to be displaced in the manure pit for mixing and pumping the manure slurry, the pump unit having a pump outlet for discharging the manure slurry being pumped from the pump unit, and a distribution arrangement for selectively connecting the pump outlet to a selected one of a drainage and a re-circulation pipe, the distribution arrangement having a support having first and second inlets respectively connected to the drainage and re-circulation pipes;
- a distribution member mounted on one side of the support for relative movement with respect thereto, the distribution member having an outlet defined therein, the outlet being connected in flow communication with the pump outlet;
- and an actuator for displacing the distribution member from a first position in which the outlet of the distribution member is positioned in registry with the first inlet to provide a straight-through flow path from the outlet to the first inlet, and a second position in which the outlet of the distribution member is positioned in registry with the second inlet of the support to provide a straight-through flow path from the outlet to the second inlet.
