Definitions

  • the invention relates to a tubular container arranged in a stacking frame with curved or flat container bottoms for bulk material, preferably for fine dust with at least one filler neck and an emptying device and a pressure compensation device.
  • silo containers have the ISO / UIC standard or the dimensions prescribed by the railway. They can be used to transport bulk goods by road, rail or water on appropriate transport vehicles.
  • the well-known silo containers are loaded via filler necks, which are accessible from above through the stacking frame. Depending on the size, the - complete - emptying can be carried out via four, six or eight special outlets by means of stationary or stationary compressor systems with, for example, 2 atm air pressure.
  • Some silo containers also have to be tilted up to 50 ° for emptying in order to unload problematic bulk goods. Such containers then have a special discharge. (Brochure from Spitzer Silo-vehicles, D-6950 Mosbach near Heidelberg)
  • the known silo containers are used exclusively for transporting the bulk material, for example between a storage silo behind a mill or a shredding system and another storage silo in front of a further processing system. Between shredding and processing systems, the bulk goods must first be filled into a first storage silo, emptied from this - as required - for transport into the silo container and then, before further processing, transferred from the container to another storage silo using a device. This requires a considerable cost-intensive effort in terms of space, facilities and time.
  • known silo containers can be stacked according to their stacking frame dimensions, for example on transport ships or in a container terminal, but cannot be emptied when stacked.
  • the object of the present invention is to optimize the transfer of bulk materials, in particular problematic fine dust, between a comminution system and a further processing system.
  • the container arranged in a stacking frame is a rotary body mounted on rollers and rotatable about a longitudinal axis by a rotary drive or by hand, that a combined mechanical conveying device and fluidization device is provided that one of the container bottoms is designed as an emptying bottom and is combined with an emptying device which includes a passage for the bulk material through a central opening of the emptying bottom, and that the opposite container bottom is designed as a pressure equalizing bottom and is combined with a pressure equalizing device.
  • Such a container can be filled with essentially dry bulk material, preferably very fine dust, via its filler neck using a new filling device which is not part of the invention, directly from the closed system of a comminution system, and then, if necessary, stored for any length of time or on the respectively required means of transport to water the push or on the road - even over long distances.
  • the finest bulk goods in the container are unusable neither by agglomeration nor by chemical processes that may be taking place, since both can be interrupted or prevented by briefly rotating the container even if the residual moisture in the bulk goods is present.
  • the bulk material especially fine dust, can be directly and continuously released to a further processing production process without moisture absorption.
  • Fluidization is required before emptying the container if the bulk material has compressed due to gas separation due to the vibrations in the transporter (approx. 15% to 18% volume loss).
  • the fluidization blades in the container whirl up the bulk material during the rotation of the container and in the process bring it into contact with the gas bubble deposited in its upper region, the gas particles again accumulating on the surface of the solid particles. This makes the bulk material flowable. There is no enrichment of the moisture content beyond what was present when the container was filled, for example from the closed system of a shredding system.
  • the new containers can be stacked next to and on top of each other. Assuming that each container can hold about 30 tons of bulk goods, and four containers stacked on top of each other each stacking frame must be able to carry about 100 t (filling + dead weight). Because the containers are emptied via a passage in the central opening of their emptying floor, the battery-stacked containers can be connected to further line systems without difficulty and continuously discharged via them, the combined conveying and fluidizing device inside the container almost completely emptying enables and supports.
  • the container Before filling with potentially explosive bulk goods, the container is flushed with inert gas. It remains filled with this inert gas at a pressure of 0.2 bar and is thus rendered inert.
  • the inerting device belonging to the container is controlled via an O2 measuring point, which keeps the O2 content constant at about 6%.
  • dehumidified gas depending on the risk of explosion of the bulk material, air or inert gas
  • dehumidified gas can be used for gas compensation to equalize the pressure when the container is emptied, if the residual moisture content of the bulk material to be processed must not deteriorate.
  • the container In order to be able to discharge the frictional electricity that may arise during the fluidization process, the container is grounded opposite the stacking frame.
  • the stacking frame or the container is equipped with a transport lock, which holds the container securely in its stacking frame even when braking hard or in the event of unforeseen movements.
  • the transport lock can be operatively connected so that it cannot be switched on until the transport lock has been released.
  • the container can be stored on castors and its rotary drive can be done in different ways.
  • races are attached to the container and a separate drive ring is provided.
  • Each race ring is attached to the outer casing and is in running connection with four running rollers, each of which is mounted in a running frame of the stacking frame.
  • the drive ring is paired with a drive element which is connected to the rotary drive via a reduction gear.
  • the pairing between the drive ring and the drive element can take place as a sprocket, pinion, rack, chain, but also as a worm gear pairing. In the latter case, the reduction gear is designed as an angular gear.
  • two races are provided on the outer jacket of the container. Each of these races is operatively connected to three rollers and a drive wheel.
  • the rollers and the drive wheels are each mounted in the corners of a running frame of the stacking frame. At least one of the drive wheels mounted in a lower corner of the running frame is connected to the rotary drive via a reduction gear. Both drive wheels can be coupled to one another via a drive shaft.
  • the reduction gear can be rotatably connected with a hand crank in order to be able to empty the container in the event of a power failure or where the rotary drive of the container cannot be connected to a network.
  • the rotary drive includes a rotary motor that sits in the stacking frame and is an adjustable electric motor. This can be used to control the emptying of a container, but also of all containers stacked in a battery, for example via a process computer, and to adapt it to the requirements of a further processing process.
  • the mechanical combined conveying and fluidizing device includes one or more screw spirals fastened between the container bottoms on the inner casing, between which are located fluidizing blades arranged offset to one another and running in the direction of the longitudinal axis of the container.
  • the slope of the spiral screws towards the emptying floor can become smaller.
  • the screw spirals also transport the bulk material to the discharge floor. The design of the screw spirals allows the transport speed in connection with the rotation of the container to be influenced depending on the nature of the bulk material for which the containers are intended in the individual case.
  • the essence of the different emptying devices connected to the container is the material leadthrough the central opening in the emptying floor, which enables emptying when the container is rotating.
  • the emptying device is a suction emptying device
  • the feedthrough which is guided through the emptying base is a rotary feedthrough, at the outer end of which a suction connection is connected and at the inner end of which a suction nozzle is also directed downwards when the container is rotating, the lower end of which ends in a bulk material collecting space.
  • the bulk material which may have collapsed, must be loosened and made flowable. This is done by rotating the container without the suction emptying device being switched on.
  • suction emptying device in particular the rotary feedthrough, is combined with a so-called torque support, by means of which it is essentially achieved that the suction connection of the emptying device remains stationary with respect to the stacking structure even when the container is rotating. Details of the suction drain device tion can be found in claims 18 to 29.
  • a second exemplary embodiment of the emptying device is designed as a mechanical emptying device which includes a blade arrangement fastened to the inside of the emptying base.
  • the feedthrough in the drainage floor combined with this drainage device is also a rotary feedthrough. Details of this emptying device result from claims 30 to 35.
  • a third, relatively simple embodiment of a mechanical emptying device is characterized in claims 36 to 41.
  • This emptying device works independently of stationary auxiliary units or an electrical voltage. The emptying is accomplished simply by rotating the container within the stacking frame, in an emergency by hand drive.
  • a pressure compensation device is used when emptying, which is combined with the pressure compensation base. It essentially includes a gas feed-through, the gas feed-through receptacle fastened in the center of the pressure compensation base via star-shaped connecting lines connected to gas feed-throughs located at the outer edge of the pressure compensation base, and to the part of which is fixed relative to the stacking structure, a gas line is connected.
  • This gas line can be connected to air or gas bottles arranged in the stacking frame or also to a simple air inlet valve, which, however, is only used if the nature of the bulk material allows contact with the atmospheric air during emptying.
  • Each gas feedthrough near the circumference of the pressure compensation base is combined with a shut-off valve, the actuating plunger of which is on an am for the duration of a gassing period
  • Stacking cam attached control curve is present.
  • the arrangement is such that gassing of the container interior always and only takes place when the check valve currently in operation passes the control curve in the upper region.
  • an O2 measuring point can be arranged inside the container, which are in electrical connection with switching valves on the gas bottles in switching connection. If the O2 content inside the container should become too high, inert gas can be automatically filled into the container.
