A pneumatic nozzle capable of removing dry solid debris, liquids, and mixtures of solid and liquid waste is provided. The pneumatic nozzle uses a pressurized gas stream to push materials through the nozzle. The force of a pressurized gas stream provides a partial vacuum to allow material to be introduced into an opening of a nozzle via a slight suction force. Thereafter, individual particles and materials introduced into the pneumatic nozzle are pushed by a stream of pressurized gas through the nozzle.

The invention claimed is: 1. A pneumatic nozzle comprising: a substantially linear conduit having a material inlet defined along one end of the conduit and an outlet defined on the opposite end of the conduit; a coupling attached to a side of the conduit, the coupling adapted for introducing a pressurized supply gas into a receiving chamber defined within an interior of the conduit, the receiving chamber having disposed therein a conical plug in which the outer wall is tapered toward the outlet, the conical plug further defining a bore therethrough, the bore being in axial alignment with the inlet and the outlet of the conduit; wherein when the supply gas is introduced through the coupling, the supply gas enters a cylindrical-shaped chamber and is directed along a gap defined between the outer wall of the conical plug and an interior nozzle wall toward the outlet, the flow of the supply gas creating a negative pressure at the inlet which may be used to introduce a material into the interior of the nozzle, where the supply gas pushes the material toward an outlet of the nozzle. 2. A nozzle for the uptake and transport of material comprising: a conduit having an inlet, an outlet, and an axial passageway defined therebetween; a supply gas coupling having a coupling inlet and a coupling outlet, the coupling outlet in communication with a chamber defined within said axial passageway; a plug extending from said inlet and defining a bore therebetween, said bore in alignment with said axial passageway, said plug further defining an exterior wall surface, a portion of said exterior wall surface extending through said chamber; a gap defined between said exterior wall or surface of said plug and an interior wall of said conduit, said gap providing communication between said chamber and a mixing chamber, said mixing chamber defined by an interior of said conduit and opposite a plug terminus, said mixing chamber in further communication with said outlet; wherein when a supply gas enters said chamber, said supply gas passes through said gap and enters into said mixing chamber, the flow of said supply gas through the mixing chamber establishing a reduced pressure at said inlet through which said material may enter the nozzle through an inlet, passing through the plug bore and entering into said mixing chamber. 3. The nozzle according to claim 2 wherein said exterior wall of said plug defining said gap is tapered. 4. The nozzle according to claim 3 wherein said interior wall of said conduit defining said gap is tapered. 5. The nozzle according to claim 2 wherein said plug defines a threaded exterior adapted to engage a corresponding threaded portion defined by an interior of said axial passageway in proximity to said inlet. 6. The nozzle according to claim 2 wherein the greater a length of said plug is threadably inserted into said inlet, a resulting width of said gap is decreased. 7. The nozzle according to claim 2 wherein said chamber has a cylindrical shaped inner wall. 8. The nozzle according to claim 2 wherein an inner diameter of said mixing chamber is less than an inner diameter of said axial passageway adjacent said outlet. 9. The nozzle according to claim 2 wherein said axial passageway through which material is transported is substantially linear. 10. The nozzle according to claim 2 wherein said gap for introducing a supply gas into said mixing chamber is at an angle of about 30° relative to a longitudinal axis of said passageway. 11. A process of conveying waste material through a nozzle comprising the steps of: supplying a nozzle comprising a conduit having an inlet, an outlet, and an axial passageway defined therebetween; a supply gas coupling having a coupling inlet and a coupling outlet, the coupling outlet in communication with a chamber defined within said axial passageway; a plug extending from said inlet and defining a bore therebetween, said bore in alignment with said axial passageway, said plug further defining an exterior wall surface, a portion of said exterior wall surface extending through said chamber; a gap defined between said exterior wall or surface of said plug and an interior wall of said conduit, said gap providing communication between said chamber and a mixing chamber, said mixing chamber defined by an interior of said conduit and opposite a plug terminus, said mixing chamber in further communication with said outlet; introducing into the nozzle a supply gas, the supply gas entering the nozzle under pressure and impinging upon a tapered wall positioned within a cylindrical chamber and which directs the supply gas toward an outlet; establishing a reduced pressure at an inlet of the nozzle, the reduced pressure established by the directional flow and velocity of the supply gas; introducing a waste material into the inlet, the reduced pressure conveying the waste material into an interior of the nozzle; intermixing the waste material and the supply gas within a mixing chamber defined within an interior of said nozzle; pushing the waste material from the chamber by the continuous flow of the supply gas and intermixed waste through the nozzle; wherein the waste material and the supply gas exits the nozzle.
