Definitions

  • the invention relates to a pneumatically fillable container made of flexible, airtight material, for granular, free-flowing material, with suspension devices for mounting on a support frame, with a funnel-shaped outlet that merges into an outlet connection, with a filter ceiling delimiting an air space below the container ceiling , with a filling line that ends in the center of the filling space below the filter ceiling, and with a ventilation opening that is arranged in the air space between the filter ceiling and the container ceiling.
  • Such a container is known from DE-GbM 8203988, published on July 1st, 1982.
  • the container is suspended in a support frame and has a horizontally stretched filter ceiling at a distance from the container ceiling, through which the conveyed air, which has entered the filling chamber via the filling line, can enter the intermediate space between the filling chamber and the container ceiling and is removed through the ventilation opening provided in the container ceiling .
  • the filling line is fed in parallel above the tank ceiling, is angled in the middle of the tank ceiling and passes through the tank ceiling and the filter ceiling in the vertical tank axis, opening out just below the filter ceiling. This is necessary because the filter cover is inflated with pneumatic filling. Since the ventilation opening must not be laid through the filter ceiling, the ventilation opening is provided in the immediate vicinity of the filling line in the container ceiling, so that the section of the filling line provided in the space serves as a spacer for the filter ceiling.
  • Containers of this type in particular storage containers for coal, usually have to be accommodated in rooms of limited height, especially in very low basement rooms. On the other hand, of course, is as large as possible Capacity of the container is desirable, for example, to accommodate the entire amount necessary for a heating period.
  • the usable height of the container is determined by the slope angle of the filling material, which is also decisive for the emptiness.
  • the maximum usable container volume therefore corresponds to two cones with the base facing each other.
  • These containers can, for example, be part of pourable fuels, as are described, for example, in DE-OS 32 05 146.
  • malfunctions occur repeatedly, which, in contrast to pressure conveyors, cannot be remedied by the suction conveyor system, which leads to bridges forming in the container outlet, blockages in the suction lines, since these were not completely emptied when the conveyance was interrupted, etc.
  • These malfunctions are usually corrected arduous since, for example, clogged lines can only be emptied after complete disassembly.
  • the invention has now set itself the task of significantly increasing the capacity of such a container while maintaining the overall height.
  • the container should be provided with a discharge device, in which malfunctions are largely excluded and troubleshooting is made possible by easy dismantling in the simplest possible manner.
  • the increase in the capacity of such containers can be achieved, for example, by arranging the filter ceiling to rise towards the filling opening of the filling line. If the filter ceiling is braced horizontally, the vertical distance from the slope line of the filling material becomes with increasing distance from the vertical axis of the container greater.
  • the filter cover can therefore be attached to the side wall in the space remaining outside the upper cone, ie deeper than before, and pulled up to the filling line. This results in the possibility of arranging the end of the filling line higher, so that its section penetrating the air space is shortened and the usable height is increased.
  • the filling opening of the filling line can be arranged, in particular, at the smallest possible distance to a level that limits the overall height, for example the room - in particular the basement ceiling - if the ventilation opening of the air space is arranged in the region of the upper edge of the container. If the filter ceiling rises towards the center, its distance from the top edge is greatest, so that the vent opening cannot be closed even when the filter ceiling is inflated to the maximum. In this embodiment, the filter cover can therefore even be connected to the container cover in the peripheral region of the incoming filling line.
  • the maximum distance from the filter ceiling to the top edge, in the area of which the ventilation opening is located represents the height on the hypotenuse of a right-angled triangle in which the hypotenuse of the filter ceiling and the two cathets correspond to the edge-near sections of the container ceiling and the side wall .
  • the smallest possible distance between the filling opening and the plane that limits the overall height is determined by the outer diameter of the filling line, which is immediately after the line elbow. flows into the filling chamber.
  • the filling line can be known. Be fed way above the tank ceiling. If the ventilation opening is provided in the side wall next to the upper edge, the filling line is also fed through the side wall directly below the tank ceiling without loss of useful height. Since the container ceiling can in this case lie directly on the upper room delimitation plane, the distance between the filling opening and the room delimitation plane essentially also only depends on the diameter of the filling line.
  • the filling line can have a filling opening that is larger than its cross section. It can also be branched in the central area and have a filling opening in each branch.
  • the upper bulk cone of the material to be conveyed in the container is converted into an approximate truncated cone, the top surface delimitation line of which is formed by an encircling line of all filling openings.
  • the capacity can also be increased by taking measures in the lower part of the container, whereby the combination of all measures naturally has the greatest possible effect.
  • the height of a discharge device attached to the outlet connector of the container should also be as low as possible so as not to impair the usable height. Vibratory conveyor troughs are particularly suitable for this purpose, and their inflow opening can generally be smaller than the cross section of the outlet connection. A taper must therefore be provided between these two.
  • this is designed as a funnel insert for the outlet connecting piece, the one side wall of the funnel-shaped outlet extending into a funnel neck funnel bottom and a ring fleece surrounding this, which extends downward from the upper edge of the funnel bottom and is braced with the outlet neck of the container.
  • the funnel nozzle of the funnel insert is essentially at the same height as the outlet nozzle itself or only slightly lower.
  • the funnel insert is preferably inserted into the outlet nozzle from above, in a preferred embodiment the funnel bottom extending over the ring flange parallel to the adjoining area of the side wall of the Spout protruding, annular support projection.
  • the funnel-shaped outlet of the container When using a vibratory conveyor as a discharge device, at least the funnel-shaped outlet of the container also vibrates. This enables yet another measure to increase the usable space of the container. This consists in that the inclination of the side wall, at least in the area adjoining the outlet connection, is less than the natural slope angle of the free-flowing material.
  • the vibration drive also discharges the material lying there within the natural slope angle. In the area adjoining the outlet nozzle, the side walls can be cut parabolically, as a result of which the usable space is increased again, the amount of curvature decreasing towards the outlet nozzle.
  • the vibration discharge device comprises a vibrating conveyor trough which is closed at the top and which can be attached to the outlet nozzle of the container essentially perpendicular to the nozzle axis, and in which a dividing wall which keeps the vibrating conveyor height smaller than the trough height extends downward from the cover plate of the vibratory conveyor trough.
  • a further saving in height can be achieved by that the funnel neck is provided with an external thread which can be screwed into an annular web with an internal thread inserted into the cover plate.
  • the ring web protruding into the vibrating conveyor trough can at the same time form the partition which limits the height of the vibrating conveyor, since the height of the ring web cannot fall below a certain dimension when the funnel nozzle is screwed in.
  • a connecting piece of a suction line leads laterally away from the space of the closed vibrating conveyor trough that remains outside the natural cone of material emerging through the outlet piece of the container, the projection of the partition wall in the longitudinal direction of the channel onto the connecting piece of the suction line partially, preferably about a third, covering its mouth cross section.
  • a short-path vibratory feed stage is placed in front of the actual suction feed.
  • the vibration conveyor takes the material to be conveyed directly from the container, whereby the formation of bridges in the container outlet is also prevented by the vibration and moves it at least until the material to be taken over by the suction conveyor system loosely and without exposure to the material contained in the container in the vibrating conveyor trough Available.
  • the connecting piece of the suction line is arranged on a lateral, detachably fastened end plate of the vibrating conveyor trough. After removal of the end plate, the entire length of the vibrating conveyor trough is accessible.
  • the partition extends approximately in a tangential plane of the bottom surface of the natural pouring cone.
  • a separate partition is thus designed to limit the height of the material to be conveyed, the arrangement in the tangential plane having proven particularly advantageous to the experiments. It has also proven to be advantageous if the partition extends approximately over the upper half of the channel height and the upper edge of the mouth cross section of the connecting piece is approximately two thirds of the channel height.
  • the connecting piece of the suction line is preferably represented by a straight piece of pipe which extends through the end plate at approximately 45 ° and which is cut on the inside parallel to the end plate.
  • the attachment of the partition can also be achieved in that at least one arm extends from the part of the connecting piece protruding into the inside of the vibrating conveyor trough parallel to the trough bottom, at the free end of which the partition is attached, so that even in this case after removing the end plate entire vibratory conveyor trough is freely accessible.
  • an opening is arranged in the surrounding area of the channel bottom on the connection piece side.
  • coal has a tendency to release contained water that drips from the container into the vibrating conveyor trough.
  • the container connection is outside the channel center of gravity, so that when using containers made of textile material, the weight of the channel results in a slight slope of the channel bottom.
  • the water therefore flows to the deepest area of the channel, in which the bottom opening is formed, through which it can exit the device. It works when the suction conveyor is operating the bottom opening, which is smaller than the grain size of the material to be conveyed, is not disadvantageous, since small amounts of external air enter through it, so that the conceivable escape of dust components is prevented.
