    The invention relates to a filling device for bulk material comprising a conveyor, as well as a, arranged at the discharge end of the conveyor ejector, wherein the ejector comprises a rotating ejection element, according to the preamble of claim 1.
    Filling devices of the type mentioned are also known as
    Bulk dryers are and are used, for example, for filling storage rooms or storage bunkers -with bulk material of powdery, granular, granular, semi-moist or fibrous material, e.g. Pellets or wood chips. The conveyor transports the bulk material from one job site to a
    Dispensing end, which is usually overcome a height difference. At the discharge end, the bulk material falls into the ejector, in which a rotating element the
    Bulk material ejects into the storage room. The rotating element is designed as a rotating disk with a vertical axis of rotation and radially arranged ejector plates, which is also referred to as a fan disk. The bulk material falls onto the rotating fan disc and is pushed forward
    Ejector plates also rotated. The
    Centrifugal force drives the bulk material subsequently in the radial direction to the edge of the fan disc and is finally ejected in the tangential direction. An ejector box with an ejection opening surrounds the fan disk to the bulk material targeted over the
    Eject ejection opening. The rotating ejection element is provided for this purpose .with an ejector drive, which as a rule also has its own ejector control. For the conveyor are different
    Embodiments are known, in particular screw conveyor with a worm thread and an axial worm shaft. The screw conveyor is enclosed by a conveyor tube, so that an oblique, in particular a vertical transport of the bulk material is possible. In order to be able to adapt the conveyor to different flow rates and bulk material quality, the worm shaft is equipped with its own 2
    Conveyor drive and an associated control device equipped.
    However, such an embodiment requires increased
    Control effort, since two separate drives are suitable to control, for example, to be able to react with the conveyor drive to different bulk material quality or flow rates, and with the ejector to be able to control the throwing distance. Needless to say, the use of two independent drives and their controls is also associated with a corresponding cabling effort, which increases the construction and maintenance costs. In addition, the ejector is usually located in the vicinity of the ejector, thus in an area of increased dust with appropriate cleaning and the risk of dust explosions.
    It is thus the object of the invention to carry out a filling device for bulk material so that the erection and
    Maintenance costs are reduced, and the reliability is increased. In particular, the filling device according to the invention should be low-maintenance and easy to use even with different flow rates and bulk grades and be easy to adapt to different flow rates and storage room conditions.
    These objects are achieved by the features of claim 1.
    Claim 1 relates to a filling device for bulk material comprising a conveyor, and a, arranged at the discharge end of the conveyor
    Ejection device, wherein the ejection device has a rotating ejection element. According to the invention, it is provided that the conveying device is a shaftless spiral conveyor, and the spiral conveyor and the rotating ejection element of the
    Ejector have the same drive, which is connected to the spiral conveyor and / or the rotating ejection element via a transmission gear. A shaftless spiral conveyor differs from a conventional screw conveyor in that the shaftless spiral conveyor i i carries the bulk material without medium wave. A waveless

    Spiral conveyor consists, as a rule, of a flat steel, which is drawn on dedicated production machines in the longitudinal direction screw thread defined. This results in the, for the different
    Customer requirements different spiral diameter and
    Helical pitches. Since no bearings are required at the job site of the spiral conveyor and the drive at the discharge end and outside a discharge chute and the like for the
    Bulk goods can be coupled, contamination of seals or bearings can be avoided with the bulk material. Rather, the flexible conveyor spiral is the only moving part that comes into contact with the bulk material, the bulk material itself centered in the conveyor tube and thus ensures a constant distance between the conveyor spiral and the inner wall of the conveyor tube. The shaftless spiral conveyor also offers flexibility over fluctuating flow rates, as well as variable
    Bulk quality, for example, due to varying composition of the bulk material or different moisture, since the conveyor spiral has sufficient elasticity to respond by stretching or compression to different loads. A spiral conveyor is thus user-friendly and low-maintenance, and also provides easy access to all internal components for inspection or cleaning.
    In order nevertheless to be able to interpret the ejection device independently of the conveyor, according to the invention a transmission gear is provided, via which the rotating ejection element and / or the spiral conveyor are connected to the drive. Especially for small systems this is
    Equipment on mechanical components perfectly adequate. In the course of conception of a filling device according to the invention are thus dependent on expected flow rate, bulk quality and required
    Ejection speed, the conveyor spiral of the spiral conveyor, the drive and the transmission gear designed so that both the promotion, as well as the ejection of the bulk material are usually accomplished as desired. At 4 4 ··

    On the other hand, deviations from the amount of conveyance or quality of the bulk material provide the spiral conveyor with sufficient flexibility to nevertheless ensure perfect operation of the filling device according to the invention. In this way, a reliable filling device can be realized cost-effective and low maintenance, especially in small plants.
    According to the invention, both the spiral conveyor and the rotating ejection element can be connected via a transmission gear to the drive, or the drive is arranged on the spiral conveyor and connected via a transmission gear with the rotating ejection element, or the drive is arranged on the rotating ejection element and via a transmission gear connected to the spiral conveyor. Depending on the application, one of these variants can be recommended, whereby the ejection device can also be arranged in areas exposed to dust, for example due to the arrangement of the drive on the spiral conveyor and coupling of the ejection device to the drive of the spiral conveyor via a transmission gear, since there is no danger of avoiding electrical units Dust explosions or the like is more.
    An adjustability of the transmission during operation is usually not provided. In order to achieve during operation still varying ejection behavior of the ejection device, it is further proposed that the axis of rotation of the rotating ejection element is designed to be pivotable about a vertical axis. In this way 'direction of ejection and ejection distance can be changed.
    The invention will be explained in more detail below with reference to an exemplary embodiment with the aid of the attached FIG. 1, which shows a schematic representation of a filling device according to the invention. 5 # Φ ··· »♦ · · * · Φ * ft · · · · · · · · · · Φ * > »* · ♦ # ·· ·· *«
    Obvious here is the shaftless spiral conveyor 6, which is guided within a conveying tube 7. According to the embodiment shown, a drive 1 is arranged at the discharge end of the spiral conveyor 6, wherein the discharge opening 8 for the bulk material is located below the drive 1. The bulk material is subsequently transported approximately via a Abfühxrutsche in a Auswerferkasten 3, in which a rotating ejection element 4 is arranged with a shaft 5. In the exemplary embodiment shown, it is approximately a rotating ejector disk with ejector plates arranged radially on the ejector disk. Alternatively, the ejector could also be fixed and the ejector plates at a slight distance above the
    Rotate the ejector disc. As already described, the bulk material is subsequently set in rotation by means of the rotating element 4 and thrown over an ejection opening 9 in the ejection box 3 into the storage space or storage bunker.
    The shaft 5 of the rotating ejection element 4 is connected via a transmission gear 2 to the drive 1 of the spiral conveyor 6. The rotational speed of the rotating
    Depending on the design of the transmission 2, the ejection element 4 can thus be selected independently of the conveying speed of the spiral conveyor 6 and is designed accordingly during the design of the filling device. Of course, an adjustability of the transmission gear 2 could be provided, but in small systems is usually on such
    Adjustability can be dispensed with. The rotating ejection element 4 has an axis of rotation R, which is pivotable about a vertical axis V, in that the shaft 5 is mounted correspondingly pivotable. Alternatively, the entire ejector box 3 could also be pivotably mounted, with a shaft 5 fixed relative to the ejector box 3.
    Im shown. Embodiment, the Auswerferkasten 3 is arranged immediately adjacent to the spiral conveyor 6, so that it can be dispensed with about an Abführrutsche and the like, and that · bulk material falls directly from the spiral conveyor 6 in the Auswerferkasten 3. However, it would also be conceivable to arrange the rotating ejection element 4 coaxially with the spiral conveyor 6, wherein the rotating ejection element 4 is not directly connected to the spiral conveyor 6, but indirectly via the transmission gear 2, to further different rotational speeds of the spiral conveyor 6 and the rotating ejection element. 4 to enable.
    In the course of the conception of a filling device according to the invention thus depending on the expected delivery rate, bulk material quality and required ejection speed of the spiral conveyor 6, the drive 1 and the transmission gear 2 are designed so that both the promotion, as well as the ejection of the bulk material usually be accomplished as desired. As already mentioned, the spiral conveyor 6 offers sufficient flexibility even in the event of deviations from the flow rate or bulk material quality, in order nevertheless to ensure perfect operation of the filling device according to the invention. Separate drives for the ejection device and the conveyor are therefore no longer required.
