    RECEIVING AND DOSING DEVICE FOR A PARTICLE CONVEYOR
    The present invention relates to a receiving and metering device for a particle conveying system for the transport of bulk material in a conveying tube by means of a conveying element.
    STATE OF THE ART
    Particle conveyors for transporting small particles are used in many fields. Applications can be found in the food industry, agriculture, the construction industry, but also in the field of heating buildings with renewable fuels (such as wood chips or pellets from different raw materials). Here, the heating material must be transported from a storage room or storage container to the solid fuel boiler. The recording of the heating material in a delivery pipe takes place at one or more points near one end of a pipe, whereas the discharge takes place at one or more points close to the other end of the pipe.
    Such a particle conveyor system with delivery pipe and receiving devices is already described in the own utility model DE 20 2005 008 323 U1.
    In order to ensure a uniform and trouble-free loading of the conveyor tube with material at the receiving points and a uniform dosage is achieved, receiving funnels are attached to the receiving points, as they are already known from DE 20 201 698 U1.
    For material removal and other loosening and feed wheels are already known, for example from DE 41 32 237. Here wheels are mounted in the mixer removal, the material itself or take loosen with the disadvantage that large amounts of material under the inflowing pressure have to be moved. The same applies to US 2,796,202. The metering device described in DE 814962 even has to be operated manually.
    An improved recording and dosing device is also known from DE 20 2007 002 909 U1. Here, the movement of the screw conveyor is transmitted via a gear to a metering flap on the receiving hopper. Here, the metering flap performs a folding movement, which alternately opens and closes or increases and decreases the inlet area in the conveying tube. By this folding movement, the contents are kept in motion and ensures a continuous Nachfließen and thus prevents clogging. However, a serious disadvantage is also here that the folding movement takes place counter to the flow direction of the bulk material and thus an unnecessary effort is necessary.
    The main disadvantage of this solution are the large driving forces that must be exerted by the auger on the gear to move the dosing. The force is further increased by the fact that several receiving devices are mounted in a line on a particle conveyor. Depending on the length of the tube, the dimensioning of tube and screw or spiral, the rotational speed of the screw or spiral, the nature of the bulk material, the dosage of the bulk material to be transported, the force varies. But force can only be provided at one or both ends of the axisless spiral and is often a limiting factor for the length and dimensioning of the particle transport device. In addition, caused by the opening and closing noise, which can be passed on in particular over the delivery pipe over long distances. Next occurs in the transmission of the rotation of the screw via a gear on a folding movement of the metering due to the large forces required at several points wear, primarily by friction. 1/6 Austrian Patent Office AT12 854U1 2012-12-15
    TASK
    The object of this invention is therefore to provide a receiving and metering device for the promotion of loose bulk materials, which has the known advantages and also avoids the disadvantages described above, in particular works as quietly and largely wear-free. Another object is to provide a metering available that can be operated with less effort and yet ensures proper dosing.
    This object is achieved by a receiving and metering device with the features of claim 1.
    Embodiment
    Further details, features and advantages will become apparent from the following description of an embodiment of a recording and dosing device shown in the drawings, as well as from the subsequent claims.
    1 is a schematic sectional view of a conveying pipe with attached receiving and metering device perpendicular to the conveying tube axis. [0013] FIG. 2 is a schematic sectional view of a conveying tube with attached receiving and metering device parallel to the conveying tube axis [0014] FIG 1 shows, in a schematic sectional view, perpendicular to the longitudinal axis of the delivery tube 22, the receiving and metering device 10 mounted on this delivery tube 22, consisting of a receiving hopper 12 with cover element 14 and a metering element 16, which is here designed as a piece of sheet metal and at its end upper end via at least one fastener 18 is suspended on the receiving hopper 12 and is guided near its lower end by at least one rear guide element 42, such that the metering element 16 is laterally movable and can perform oscillations.
    The lower end of the metering element 16 protrudes into a recessed from the wall of the conveying pipe 22 inlet region 26. In the delivery pipe 22 is the conveying element 24, here a rotating spiral, which ensures the transport of the bulk material in the direction of the axis of the conveying tube 22 ,
    The movement of the conveying element 24 is picked up by a gear 28 and by means of a driver element 30 via at least one stop element 32 which is fixed to the back of the metering element 16, in a sliding or oscillating movement of the metering element 16 in the direction of the longitudinal axis of Conveyor tube 22 implemented. This power transmission through the driver element 30 can be carried out in a stop element 32 only in one direction and the return of the pendulum plate 16 via a spring element, or as in this embodiment by two stop elements 32 in both directions, ie back and forth. Since the metering element 16 in this embodiment is a pendulum about the suspension 18 back and forth, the name pendulum plate is used.
    In order to allow a sliding or pendulum motion without much effort and with little wear, the rear guide elements 42 are provided to the pendulum plate out with a ball bearing support element 20, for example a roller which is fastened with a screw on the guide member 42. The fact that the oscillations are linear in the plane of the direction of the spiral and the gear, the shuttle plate is much less friction and moves with less effort. This is just a significant advantage over a pendulum plate, which must be moved with strokes perpendicular to the direction of the spiral, so with pressure against the bulk material.
    The lateral ends of the pendulum plate 16 are guided in the pendulum motion of front guide elements 40 and secured against falling out, which are attached or formed on the receiving hopper 12 and, for example, as angled plates front over the 2/6

    Claims (6)
    [1]
    Austrian Patent Office AT 12 854 Ul 2012-12-15 Swing plate 16 grip. These front guide elements 40 are usually not on the pendulum plate 16, since the latter is pressed by the bulk material to the rear guide elements 42. There is no friction between the front guide element 40 and the pendulum plate 16. The pendulum plate 16 is preferably not flat, but slightly angled and cranked, so that in the reciprocating motion on the outside of the pendulum flap 16 adjacent bulk material in addition to the frictional force an additional force is exerted perpendicular to the surface of the pendulum plate 16 by the movement. The bulk material is constantly moved and shaken by the movement of the pendulum plate 16. The bulk material is kept in motion and a continuous Nachfließen is ensured and prevents clogging. The slight cranking of the pendulum plate 16 is possible because the front guide elements 40 as described in the previous paragraph may have the required distance to the shuttle plate without affecting the leadership and assurance. Figure 2 shows that the receiving and metering device 10 is placed in a vertical sectional plane via two clamping holder 38 on the conveyor tube 22. The pendulum plate 16 does not fully cover the cutout in the conveying tube 22 and thus leaves open an inlet region 26 for the bulk material. As already mentioned, the bulk material is constantly kept in motion by the shuttle plate and trickles into the inlet region 26 and is then carried along by the spiral 24. Further, in Figure 2 it can be seen how the teeth 34 of the gear 28 engage in the spiral 24 and transmits the rotational movement of the spiral 24 in a direction perpendicular to the axis of this first rotary motion rotational movement 36 of the gear 28. On the gear 28, a driver 30 is mounted, for example, a screw-mounted nut and ball-bearing roller. Upon rotation of the gear 28 in a direction shown by the arrow, the driver 30 exerts a force on a stop element 32 and thus causes a pendulum movement of the pendulum plate in the direction of the respective stop element 32. Thereby that once against the left and then against the right Stop element, a force is exerted, the already mentioned pendulum movement of the pendulum plate 16 is formed around the suspension point 18. The mentioned ball bearing additionally helps to minimize both wear and noise. Claims 1.
