Definitions

  • ABSTRACT A system for handling and emptying containers for fluid or pulverulent material.
  • the container includes a discharge opening adjacent a lowermost corner and near a longitudinal edge.
  • a second opening is provided at a remote corner of the container for allowing pressure compensation.
  • the container is placed upon a suitable support means so that the longitudinal edge comprises the lowermost portion of the container which is then placed within a pressure vessel through an access opening in one end thereof.
  • One of the objectives of the present invention is to eliminate the disadvantages present in the prior art and 4 does so by providing the pressure vessel with a removable wall adjacent the tilting axis so'that the discharge opening of the container is readily'accessible'when the pressure vessel is open. Means are provided for inserting the container, quadrangle in its cross-section, so that the discharge opening is arranged at the container end near thebottom the bottom thereof and in the vicinity of one of its longitudinal edges.
  • the container is specially oriented within the pressure vessel so that the discharge opening is adjacent the lowermost point of the container and the discharge opening is conveniently accessible for being connected with the flowpipe discharge means of the pressure vessel.
  • means for inserting the container into the pressure vessel including guides which extend into the interior of the pressure vessel after the wall of the pressure vessel has been removed to provide the opening therein.
  • the invention further provides for a lifting apparatus for the container in front of the removable or pivotable face wall of the-pressure vessel over the guide means extending thereinto.
  • the lifting apparatus is used to suspend the container so that the longitudinal edge adjacent to the discharge opening is located downwardly, and the container is readily placed upon a wheeled vehicle in this position and then moved through the opening and into the pressure vessel.
  • a still further object of the invention is to provide lifting apparatus for the container in front of the openable wall member of the pressure vessel for positioning the container upon a wheeled vehicle so that the discharge opening of the container is adjacent a lowermost longitudinal edge when the wheeled vehicle and container are moved into the pressure vessel upon guide rails extending therein.
  • FIG. 1 is a perspective view and shows a container capable of being filledwith bulk material and provided with a lower discharge opening and an upper vent opening.
  • FIG. 2 is a side elevation of the container resting upon a flat support surface prior to being lifted and rotated by a preferred lifting apparatus.
  • FIG. 3 is a side elevation view showing the container supported in a preferred orientation by the lifting apparatus.
  • FIG. 4 is an end view of a wheeled vehicle positioned to receive the container.
  • FIG. 5 is a side elevation of a stationary tiltably supported pressure vessel having an end wall shown in open position, the pressure vessel being pivotally mounted adjacent the openable end thereof.
  • FIG. 6 is a side elevation of the pressure vessel in tilted position with the container being disposed therein in the emptying position.
  • FIG. 7 is an elevational view, with portions broken away, and shows the tilted pressure vessel with the container disposed therein and pressure lines and discharge lines inoperative positions.
  • the container 1 is quadrangle in cross-section and is provided with a pair of filling openings capable of being closed by covers 2, a discharge opening 3 located at a lower portion thereof, and a pressure compensation opening 4 located at a diagonal, uppermost corner from the discharge opening 3.
  • the discharge opening 3 is shown as being located closely adjacent a longitudinal edge 6 of the container 1.
  • a lifting apparatus including a sling and cable 7 is attached to the container l in such a way that is suspended with the longitudinal edge 6, which is adjacent to the discharge opening 3, in a lowermost position when the container 1 is lifted in'the manner best shown in FIG. 3.
  • the container 1 is placed upon awheeled, rail vehicle 8 which is guidably supported upon rails 9.
  • pressure vessel adjacent the wall member 11.
  • the discharge opening 3 can be readily connected through the wall of the pressure vessel to an area, such as a receiving tank (not shown) outside of the pressure vessel.
  • a pipe 12 is extended through and is welded to, the cylindrical side wall of the pressure vessel 10.
  • the end of the pipe 12 which extends into the pressure vessel is capable of being connected in a simple manner by a hose 13 to the discharge opening 3 of the container 1, for an example, by means of a bayonet connection.
  • the wall member 11 is pivoted to its closed position and hermetically seals the pressure vessel 10.
  • the pressure vessel, and the container 1 and wheeled vehicle 8 disposed therein are tilted upwardly by means such as a fluid motor.
  • the side walls and end wall thereof guide the material within the container towards the discharge opening 3 so that a substantially complete emptying of the container 1 is permitted without requiring additional baffles within the container 1.
  • compressed air is blown into the pressure vessel 10 from a compressor 14 through a conduit 15.
  • The'compressed air also enters the interior of the container 1 through the pressure compensation opening 4 and forces the bulk material out of the discharge opening 3 through the hose conduit 13 and the pipe 12, which is welded into the wall of the pressure vessel 10, to a conduit 16, which provides a flow path for moving the material from the container 1 to a desired location such as a receiving tank or reservoir (not shown).
  • a system for pneumatically emptying a container filled with material and having a discharge opening disposed at a bottom portion thereof wherein said container is inserted within a pressure vessel and prior to being subjected to pneumatic pressure the interior of said container is opened to that of the pressure vessel and to an area outside of said pressure vessel, said pressure vessel and said container then being raised into an inclined position about a tilting axis and subjected to pneumatic pressure within the interior of said pressure vessel, the improvement being characterized in that said pressure vessel includes an openable wall member means located adjacent to said tilting axis for providing a passageway through which said container can be moved into and out of said pressure vessel, said pressure vessel including connection means formed therein and located closely adjacent to said passageway for connecting with said discharge opening of said container and providing a flow path for moving said material between the interior of said container and the exterior of said pressure vessel, and a wheeled vehicle movable into said pressure vessel and including support means thereon for supporting said container in a position such that a longitudinal edge comprises the lowermost portion of said container.
