    description
    RECEIVING AND DOSING DEVICE FOR A PARTICLE CONVEYOR
    In the own German utility model 202 01 698 U1 a receiving hopper for transporting wood pellets in a pipe conveyor systems is described, the doses fed through an opening in the conveyor tube, the wood pellets. In addition to wood pellets, it is also possible to promote wood chips, planing slats, sawdust, grinding dust, wood waste, cardboard shreds from a supply not only for loading heating but also for further processing or for loading vehicles. The disposal of end products from filter systems or shredders happens here largely dust-free and almost noiseless. There is no pressure on the conveyed material. As a result, these conveyor systems can also be used in the foodstuffs, plastics industry or in general in chemistry.
    This known receiving hopper ensures as part of a transport unit for wood pellets - heating systems, the constant supply of wood pellets or similar particulate heating materials from a storage room to the heating system. An essential element here is that the supply of wood pellets from the supply in the delivery tube of a pendulum flap is well dosed, which rests positively on a in the known device spiral as a conveying element so that the pendulum flap commutes, that is, the transition of the amount of particulate Heating materials in accordance with the movement of the conveyor spiral controls.
    There are now a variety of alternative fuels for the operation of pellet stoves. The so-called energy cereal, a special protein-rich cereal is usually also pelleted, but also granular fired. Furthermore, experiments are done with cores of different plants and with pellets from fast-growing plants such as Miscan -thus (Miscanthus).
    For all types of alternative fuels or other goods it is more important that the known from German utility model 202 01 698 U1 pendulum flap works well as a metering device and to prevent lumping. It is known that it receives its mobility in that it rests on the moving conveyor spiral and receives a reciprocating motion granted by the rotation of the spiral.
    In a further embodiment is described in the further own utility model DE 20 2005 008 323 U1, that a plurality of such successively arranged recording funnel with oscillating dosing record the conveyed in a conveyor tube.
    Hence, the task of further developing a receiving and metering device described above, wherein as conveying element not spirals or screws but also chains or other moving in the conveying tube funding one of the conveying movement corresponding pendulum movement of the metering can cause.
    As in the cited prior art has a receiving hopper with a pendulum flap advantages. In order to prevent overfilling of the conveyor tube with materials, a number and size of the opening were matched to the conveyed material according to a prior art, on the other hand, the spiral is connected in the region of the opening with an inner tube. With these measures but could not yet be solved the problem of clogging or idling of the conveyor tube, as just formed at the openings cavities in the stored materials and thus the supply was interrupted in the delivery pipe. It came to so-called bridge formations. In the case of, for example, storage rooms completely filled with wood pellets, pressure was also exerted on the delivery spiral so that initially too much material flowed in and thus overfilling or obstruction of the delivery pipe occurred.
    The solution to the problem posed here, instead of a dosing flap resting loosely on a spiral through which a dosing flap swings back and forth during the movement of the worm, results from the main claim, which is Austrian Patent Office AT12 853U1 2012-12-15 designs the dependent claims and the description of the figures can be found.
    Further features and details will become apparent from the following description of the accompanying schematic drawing.
    Figure 1 shows a schematic section through a feeding device according to the inven tion and Figure 2 is a plan view somewhat obliquely from the front to the device shown in Figure 1 Vorrich, partially in section.
    In a conveying tube 10 is in the example shown as a conveying element a conveyor spiral 12 which moves in the representation of Figure 2 in the direction of the arrow 14 fixed and thus moves the conveyed in the illustration of Figure 2 from left to right. At the same time, a gear wheel 16, which is arranged freely rotatable behind a metering flap 20, is also rotated in the direction of the arrow 18 by this movement. For this, the teeth 22 protrude into the above the axis of rotation in the conveying spiral 12 and the gear 16 is rotated by the rotational movement of the conveyor spiral 12.
    This rotational movement is converted into reciprocating pivotal movement of the throttle valve 20 about the articulated bearing 24. In the illustrated embodiment, this is done via a circular ramp 26 which is connected concentrically to the hub on the side facing the metering flap 20 side of the gear 16 fixed to the gear 16. This circular ramp 26 consists of a flattened ring, the top of which increases helically up to an edge 28 in the direction of rotation and drops at the edge 28 in a flattened step.
    Concentric thereto, a uniform circular ramp 30 is mounted on the inside of the throttle valve 20 fixed axis, whose decreasing in the direction of rotation of the gear 16 descending ring up to an edge in a flattened step. Upon rotation of the gear 16, the two opposing flattened surfaces of the rising and falling rings slide on each other such that the metering flap 20 pivots about its hinge 24 in an opening slot 32 back and forth. In the process, it meters the material which penetrates into the conveying tube 10 through an inlet region 34 or dissolves congestion at this point.
    If, instead of an axisless spiral 12 exemplified here, a spindle is used, the gear 16 is adapted in the form of its teeth 22 in the spindle contour. When using a revolving conveyor chain, the chain links receive corresponding projections which engage between the teeth 22 of the gear 16 and rotate the wheel 16 in accordance with the running speed of the chain. In any case, the metering flap 20 moves proportionally to the conveying speed of the material in the conveying tube 10 and without its own drive.
    The entire feeder is easily inclined to the material task on the conveyor tube 10 and is connected to clamps 36 with the conveyor tube 10. 2.4
