Abstract: A nozzle for introducing pressurized fluids into an industrial vessel is releasably attachable to and detachable from a mounting member securedly attached to an exterior surface of the vessel. The mounting member is attached, via extension piping, to a source of pressurized gas, such as the exhaust valve of an air cannon. Both the nozzle and the mounting member include respective mating collars which engage each other in a twist lock manner. Additional securing members are provided to securely retain the nozzle and mounting member in twist lock engagement. Removal of the nozzle is performed by releasing the securing members, twisting the nozzle from inside of the vessel to unlock it from the mounting member, and uncoupling the nozzle from the mounting member. Installation of a replacement nozzle is performed by performing the foregoing steps in the reverse order.

Abstract: A gas channeling device for selectively channeling blasts of gas from an air cannon to various locations comprises a stationary portion and a movable portion. The stationary portion comprises a fluid inlet passageway and at least first and second fluid outlet passageways. The movable portion comprises a fluid channeling passageway, and is pivotally movable about a pivot axis relative to the stationary portion in a manner such that the movable portion can be selectively positioned in alternative first and second positions relative to the stationary portion. The fluid channeling passageway operatively connects the fluid inlet passageway to the first fluid outlet passageway when the movable portion is in the first position. The fluid channeling passageway operatively connects the fluid inlet passageway to the second fluid outlet passageway when the movable portion is in the second position.

Abstract: An air cannon or aerator comprises a tank, a valve, and a tube. The tank has opposite first and second openings and an interior chamber. The valve is rigidly attached to the first opening. The tube connects the valve to the second opening of the tank through the interior chamber of the tank. The tube is pivotally connected to each of the first and second openings and comprises a fluid passageway. The valve is configured and adapted to selectively allow gas to pass from the interior chamber of the tank into the fluid passageway of the tube and out of the tank through the second opening and to selectively prevent gas from passing from the interior of the tank into the fluid passageway of the tube.

Abstract: An air cannon or aerator has a first source of a pressurized gas, such as a tank, a discharge tube assembly, a valve assembly configured to regulate the flow of pressurized gas from the tank to the discharge tube assembly, and a receiving member or basket having a first end configured to receive and seat the valve assembly and a second end configured to releasably and securely mate with the discharge tube assembly. The discharge tube assembly, valve assembly, and basket are all concentrically aligned along a central, longitudinal axis extending substantially coaxial with the longitudinal center line of the tank.

Abstract: A positive pressure actuated aerator valve assembly adapted to discharge compressed gas into the chamber of a bulk material handling structure. The aerator valve assembly includes a housing and positive pressure actuated valve. The housing includes a chamber adapted to receive compressed gas and a discharge piston slideable between an extended position and a retracted position. The valve includes a valve body having an actuator piston seat and a fluid vent passageway in fluid communication with the actuator piston seat. An actuator piston is slideable with respect to the valve body between a retracted position and an extended position.
