Definitions

  • the invention relates to a device for automatically transporting granular material.
  • the device is characterized in that provision is made of a transport duct, which has a mouthpiece provided with a central jet pipe and located at a certain distance from the sucking end of the transport duct and capable of closing completely the mouth of the transport duct against the pressure of a spring, whilst during operation a gas under a comparatively high pressure is conveyed through each jet pipe and the transport duct is furthermore provided with one or more jet pipes arranged in the wall thereof and extending approximately in the direction of transport, which pipes are fed, during operation, also by a gas under a comparatively high pressure.
  • the mouthpiece is secured by means of at least two guides to a sliding piece surrounding the transport duct, one of the guides being used as a supply duct for the gas.
  • reference numeral 1 designates a transport duct, which has a gland 2, secured rigidly to the duct.
  • a sliding piece 3 which is adapted to slide along the duct, and between the sliding piece 3 and the gland 2 is provided a pressure spring 4.
  • the duct is provided with a bent-over edge 5, so that the sliding piece 3 cannot be removed fro-m the duct.
  • a mouthpiece 6 is provided with a jet pipe 7 and is secured by a connecting rod 8 to the sliding piece 3.
  • the other connection between the sliding piece 3 and the mouthpiece 6 is formed by a duct 9, to which a duct for compressed air is connected.
  • the air has an overpressure of 3 to 4 atmospheres.
  • This housing has a connection 12, through which also compressed air of 3 to 4 atmospheres can be introduced into the housing 11.
  • the fiow of air through the jet pipe 7 agitats a quantity of grains.
  • the grains obtain a certain initial velocity and the air flowing through the jet pipes it] sucks up the agitated grains, which already have a certain velocity and transports them further.
  • the opening of the transport duct in the vessel, to which the grains to be transported are supplied is completely closed, no grains are any longer transported, since the opening cannot be blown free, so that no flow of air occurs any longer in the duct.
  • the opening is again free, the material being removed from the vessel, for example via a drain in the bottom or" the vessel, the transport is automatically resumed.
  • the device itself can be manufactured in a simple manner and it should be noted that, for example, no cyclone is required to separate the material to be transported from the air. Moreover, it is found that a comparatively small quantity of air is required to transport of the aforesaid quantity.
  • a device for transporting dry granular material from one storage vessel to a second storage vessel comprising a tubular transport member having an inlet opening adapted to be imbedded in the material and an outlet opening adapted to be arranged in the vicinity of the second storage vessel, a compressed gas jet mounted on said member with its orifice within the member and directed toward the outlet opening, a closure member movably mounted on said member at the inlet opening, resilient means urging said closure member away from the inlet opening to form a space, and a compressed gas jet mounted on said closure member and directed through said space toward the inlet opening.
