Abstract
An apparatus for agitating and pumping a liquid slurry, such as liquid manure slurry. The apparatus includes a pump which is adapted to be positioned within the lower end of a pit that contains the slurry, and the pump is operably connected to a motor which is located above the pit. The motor-pump unit is mounted for sliding vertical movement on a fixed column and can also be rotated horizontally relative to the column to vary the position of the outlet of the pump during agitation of the slurry. The apparatus also includes a means for tilting the motor-pump unit with respect to the fixed column. When the pump is raised to a location adjacent the top of the pit, the motor-pump unit can be tilted in a vertical plane to move the pump out of the pit to a position where it can be repaired or maintained.
Claims12
An apparatus for agitating and pumping a liquid slurry, comprising a vessel containing the liquid slurry, a fixed vertical column disposed within said vessel, a motor-pump unit mounted for vertical movement on said column, said motor-pump unit including a pump located within the vessel for agitating and pumping the liquid slurry and a motor located a substantial distance above the pump and positioned outside the vessel, said motor-pump unit also including a driving connection between the motor and the pump, first mounting means for mounting the motor-pump unit for rotation about the axis of said column, and second mounting means connected to said motor-pump unit for mounting the motor-pump unit for tilting movement about a horizontal axis with respect to the column, said second mounting means being movable on said vertical column whereby said motor-pump unit can be moved vertically within said vessel, said motor-pump unit being movable to an upper position where the pump is located adjacent the top of the vessel and said motor-pump unit then being capable of being tilted about said horizontal axis to raise the pump to a level above the vessel.
An apparatus for agitating and pumping a liquid slurry, comprising a pit containing a liquid slurry a fixed vertical column disposed within said pit, a motor-pump unit mounted for vertical movement on said column, said motor-pump unit including a pump located within the pit for agitating and pumping the liquid slurry and a motor located a substantial distance above the pump and positioned outside the pit, said motor-pump unit also including a drive shaft connected between the motor and the pump and offset laterally from said column, first mounting means for mounting the motor-pump unit for rotation about the axis of said column, a guide member mounted for vertical movement on said column, and trunion means interconnecting said guide member and said motor-pump unit for mounting said motor-pump unit for tilting movement in a vertical plane with respect to said guide member, movement of said guide member on said column causing said pump to move vertically within said pit.
An apparatus for agitating and pumping a liquid slurry, comprising a pit containing a liquid slurry, a fixed vertical column disposed within said pit, a motor-pump unit mounted for vertical movement on said column, said motor-pump unit including a pump located within the pit for agitating and pumping the liquid slurry and a motor located a substantial distance above the pump and positioned outside the pit, said motor-pump unit also including a driving connection between the motor and the pump, first mounting means for mounting the motor-pump unit for rotation about the axis of said column, guide means for mounting said motor-pump unit for vertical movement on said column, trunion means interconnecting said guide means and said motor-pump unit for mounting said motor-pump unit for tilting movement in a vertical plane with respect to said column, locking means for preventing said motor-pump unit from being tilted about said trunion means, and means responsive to said pump being in an upper position adjacent the top of the pit for disengaging said locking means to thereby permit said motor-pump unit to be tilted about said trunion means.
An apparatus for agitating and pumping a liquid slurry, comprising a pit to contain the liquid slurry, a vertical column mounted in the pit, a motor-pump unit including a pump disposed in the pit for agitating and pumping the liquid slurry and a motor disposed a substantial distance above the pump and located upwardly of the pit, said motor-pump unit also including a driving connection between the motor and the pump, first mounting means for mounting said motor-pump unit for sliding vertical movement with respect to the column whereby the pump can move between a lower portion at the bottom of the pit to an upper position at the top of the pit, releasable connecting means for preventing relative rotation between said motor-pump unit and said column, second mounting means for mounting said motor-pump unit for rotation about a vertical axis, third mounting means for mounting said motor-pump unit for tilting movement about a horizontal axis relative to said column, and means responsive to the pump being moved to said upper position for releasing said connecting means whereby said motor-pump unit can be tilted about said horizontal axis to move said pump out of said pit.
