Definitions

  • the invention relates to a tubular container for bulk material, in particular for very fine dust, which is mounted in a stacking frame and rotatable about its longitudinal axis by a rotary drive, to whose outer casing two races for rollers are fastened, one of which container base is combined with an emptying device, one by a Central opening of the emptying floor includes a lead-through for the bulk material and a pressure compensation floor opposite the emptying floor with a gas feed-through device, and on the inner jacket of which a helix is attached which transports the bulk material to the emptying device when the container rotates.
  • Containers of this type are used exclusively for the transport of bulk goods, for example between a first storage silo behind a mill or a crushing plant and a second storage silo in front of a further processing plant.
  • the bulk material from the shredding plant is first filled into the first storage silo, emptied from it - if necessary - for transport into the container and then, before further processing, transferred from the container to another storage silo via a device, from which it - usually after a longer or shorter interim storage - must be conveyed to the processing plant.
  • This requires a considerable cost-intensive effort in terms of space, facilities and time.
  • Difficulties of a particular kind arise with problematic bulk materials, such as fine dust, which are difficult to flow when emptied or which also tend to agglomerate and form bridges.
  • a container of the type mentioned at the beginning is used, for example, for the transport of such bulk goods (EP 0 188 336). Its bottoms have supports supported in stands, around which the cylinder can rotate and from which the cylinder is supported. Through the bearings in the direction of the longitudinal axis of the container passage openings with shut-off devices are made through which the container is loaded and unloaded. Special loading and unloading devices are required for this. Races are fastened to the outer casing, which cooperate with drive wheels in two places, which at the same time can also carry at least one of the container.
  • the same features also have an embodiment of the known container, which is arranged in a stacking frame.
  • the container can also be stored in air pressure bearings, which are intended to relieve the load on the container bottoms.
  • the pivot bearings with passages on both container bases are structurally complex and expensive.
  • all of the exemplary embodiments must be connected to loading or unloading devices operated with compressed air or compressed gas.
  • the known containers cannot be loaded or unloaded without such loading and unloading devices and additional provision of compressed gas or compressed air.
  • Another disadvantage is that in all of the exemplary embodiments, the supports for the rotating cylinder stand on a platform.
  • the present invention is based on the object of moving bulk goods, in particular problematic fine dust, between a comminution system and a further processing system to optimize significantly.
  • each race cooperates with four rollers, each of which is mounted in a corner of a square running frame, which is also a supporting component of the stacking structure, that at least in the outer jacket of the container a filler neck is provided that the emptying device includes a torque arm that is supported against the stacking frame, which is combined either with a suction nozzle device that can be connected to a solid pump or with a shovel device, and that the pressure compensation device has gas bushings located on the outer edge of the pressure compensation base.
  • each race with four rollers and the arrangement of these rollers in square running frames, which are also load-bearing components of the stacking structure, gives the container excellent strength and stability with the least amount of material.
  • the stacking stand has the ISO / UIC standard or the dimensions prescribed by the railway. It can be used to easily transport bulk goods on appropriate transport vehicles by road, rail or water.
  • the container according to the invention can be filled using a new filling device not belonging to the invention directly from the closed system of a comminution system via its filler neck with essentially dry bulk material, preferably very fine dust, and then, if necessary, stored for any length of time or on the respectively required means of transport Water, by rail or on the road - even over long distances.
  • a new filling device not belonging to the invention directly from the closed system of a comminution system via its filler neck with essentially dry bulk material, preferably very fine dust, and then, if necessary, stored for any length of time or on the respectively required means of transport Water, by rail 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 emptying device either includes a suction nozzle combined with a torque arm or a shovel device in order to release the bulk material, especially fine dust, directly and continuously into a further processing process without moisture absorption. Emptying is ensured in any case by the specially designed pressure compensation device.
  • the new containers can be stacked next to and on top of each other. If one assumes that each container can hold about 30 t of bulk goods and four containers are to be 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 through 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 intertising device belonging to the container is controlled via an oxygen measuring point, which keeps the oxygen 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 fastened to the container and a separate drive ring are provided. Each race is attached to the outer jacket and is in running connection with four castors, 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, greenhouse, 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 casters 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 races are designed so that at least one race in operative connection with the rollers axially guides the container during rotation.
  • 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 screw spirals towards the emptying bottom 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 essential of the different emptying devices connected to the container is that through the central opening in the emptying floor guided material feed-through that enables emptying when the container is rotating.
  • the emptying device is a suction emptying device
  • the feedthrough which is guided through the emptying floor 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 downward 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.
  • the suction emptying device in particular the rotary feedthrough, is combined with a so-called torque support, which essentially ensures that the suction connection of the emptying device remains stationary with respect to the stacking frame even when the container is rotating. Details of the suction emptying device 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.
  • a third, relatively simple embodiment of a mechanical 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 supply, the distributor connection of which is fastened in the center of the pressure compensation base via connecting lines which are guided in a star shape to the outside edge of the pressure compensation base seated gas feedthroughs are connected to the interior of the container, and a gas line is connected to their part which is fixed relative to the stacking frame.
  • 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 bears against a control cam attached to the stacking frame for the duration of a gassing period.
  • 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 oxygen measuring point can be arranged inside the container, which is in electrical connection with switching valves on the gas cylinders. If the oxygen content inside the container should become too high, inert gas can be automatically filled into the container.
  • the filler neck, the emptying devices and the pressure compensation device are designed to be gas-tight with respect to the atmosphere.
  • the container according to the invention can equally well be used in a shredding system as a receptacle for the bulk material, as a transport vessel over long distances and as a storage container with its own emptying option - without being tipped over to have - and serve as a discharge vessel in the further processing of the bulk material, the container according to the invention allowing an optimum loading.

  • one or more helixes 55 are fastened, in the passages 57 of which fluidization blades 56 are offset with respect to one another and fastened in alignment with the longitudinal axis 32.
  • the fluidization blades 56 intensively fluidize the bulk material, which may have collapsed due to the transport, during the rotation of the container. In the process, gas particles from the upper area of the interior of the container accumulate on the bulk material particles, as a result of which the bulk material regains its original flowability, which had been lost during the transport due to degassing of the bulk material due to the shaking.
  • Fig. 1a shows a lower part of a transport lock 48. It consists essentially of a container brake pad 50 and a frame brake pad 51 opposite. Both brake pads 50 and 51 lie in the position of the container 31 shown in Fig. 1 within the Stacking stand 1 opposite.

  • the rotary block 53 is pivoted in the direction of the arrow shown in FIG. 1 a and thereby passes between the stiffening plates 49, thereby preventing the container 31 from rotating and ensuring that the brake blocks 50 and 51 lie opposite one another.
  • an oxygen measuring point 59 can be seen, which can electrically report the O2 content within the container. If this O2 content is too large, there is a risk of an explosion of the bulk material contained within the container 31. For this reason, actuation of the switching valves 22, which are seated on the gas bottles 21 according to FIG. 3, can be triggered by the oxygen measuring point via an electronic circuit, for example in the switch box 23. If these gas bottles 21 are filled with inert gas, inertization of the endangered atmosphere within the container 31 can be ensured in this way.

  • the design of the emptying end 115 according to FIG. 16 is somewhat different from that of the emptying end 107 according to FIG. 14.
  • All emptying devices 66, 81 and 105 work together with a pressure compensation device 42, through which gas can be added to the container during emptying. 10 to 13, it consists of a gas supply 43, the distributor piece 43a of which is fastened in the center 41 of the pressure compensation base 39. In the distributor piece 43a, connecting lines 44 which, as can be seen in FIG. 10, end in a star shape leading to gas passages 45, which are fastened according to FIGS. 11 and 12 along the outer edge 39a of the pressure compensation base 39 and a gas passage into the interior enable the container 31.
  • the gas feedthroughs 45 on the outer edge 39a of the pressure compensation base 39 are combined with check valves 46, which have an actuating plunger 47, for example.
  • these actuating plungers 47 run in the upper region of their orbit on a control curve 47a, which is indicated schematically in FIG. 10, so that the gas feedthroughs 45 in the upper region of the rotating container each become permeable.
  • the filler neck 54, the emptying devices 66, 81, 105 and the pressure compensation device 42 are made gas-tight with respect to the atmosphere.
