Intake nozzle for suction hose

An intake nozzle for a liquid waste suction hose, comprising

• a generally elongated tubular housing defining a housing axis and having an upper end adapted to secure to a distal end of the suction hose, a lower end having at least one opening and adapted to be inserted into a quantity of liquid waste so that the waste can be drawn up through the intake nozzle and suction hose into a storage tank;
• a rotor disposed within said housing and having a rotational axis aligned with said housing axis, the rotor including a hollow generally cylindrical canister which has an upper end, a generally cylindrical side wall, and a lower end, the lower end having one or more air outlet ports communicating the interior of the hollow canister with said quantity of liquid waste;
• an air inlet tube entering a side wall of said housing and having an outer end adapted to communicate with ambient air and an inner end aligned with the axis of the canister to communicate with the interior thereof to permit ambient air to be drawn into the interior of the canister and thence into the liquid waste in the lower end of the housing, thereby to aerate the liquid waste being drawn through the intake nozzle to facilitate passage of the waste through the suction hose into the storage tank.
