Definitions

  • the invention relates to a method and a device for discharging poorly pourable bulk materials, in particular sawdust, wood chips and wood chips, from a container.
  • containers For storage of bulk materials containers are usually filled from above and emptied through an outlet opening on the container bottom. Intermeshing or otherwise difficult pourable bulk materials, however, are not flowable even at steep angles of repose, form material bridges over the outlet opening and therefore can not leave the container without further action.
  • Out DE 197 06 407 C1 is a metering and discharge device for bulk materials is known in which a bow-shaped stirrer is attached to a metering tube with a metering.
  • the bulk material flows into the dosing tube via the dosing opening and out of an outlet at its lower end.
  • the metering tube is set in rotation about the longitudinal axis, so that the stirrer loosens the bulk material and the bulk material can be discharged via the metering opening.
  • a device for metering of powdered bulk material in which a stirring member in the form of a screw shaft discharges the bulk material from a funnel-shaped reservoir. Depending on the speed and the direction of rotation of the screw shaft, the amount of bulk material to be metered can be changed. With a screw shaft with right-hand thread, a clockwise rotation of the shaft lead to a high dosing accuracy with low mass flow rate and a left-hand rotation to a higher mass flow rate with lower dosing accuracy.
  • this device is only suitable for powdered bulk material, since this can not tilt and clump together. Poorly flowable goods, such as wood chips and wood chips tend due to their rough and jagged Surface to tilt and clumping, so that the propeller shaft is blocked.
  • Claim 2 and claims 4 to 8 include advantageous embodiments of the inventive solution of claim 1 or claim 3.
  • the poorly flowable bulk material in the container is rendered flowable by means of a first spiral-shaped stirring element and discharged from the container by means of a second spiral-shaped stirring element.
  • the first spiral-shaped stirring element and the second spiral-shaped stirring element are particularly mechanically coupled to each other, so that only one drive is required for both stirring elements.
  • the first stirrer consists of a shaft and a screw conveyor, the second stirrer of a shaft and a conveyor spiral.
  • the shaft of the first and the second agitation system is the same shaft, so that the auger and the conveyor spiral are attached to a shaft. This results particularly advantageous that only one shaft is required and space can be saved.
  • the delivery spiral is attached to the shaft so that it lies in the container above the ground, in particular directly above the ground.
  • the auger also begins in the area of the container bottom and ends in particular above the highest possible product level, where it is connected to the shaft.
  • the loosened bulk material is conveyed to the container bottom to the outlet opening, where it leaves the container.
  • the device according to the invention is particularly suitable for emptying containers which are filled with sawdust and / or wood chips.
  • the invention is explained below with reference to an embodiment and a drawing with a figure.
  • the figure shows schematically an inventive, specially shaped stirrer.
  • the agitator is shown in FIG. From a shaft 3, a screw conveyor 1 and a conveyor spiral 2.
  • the conveyor spiral 2 is attached to the shaft 3, that it comes to rest directly in the container 4 above the ground, the screw conveyor 1 also begins at the bottom of the container and ends above the highest product level, where it is connected to the shaft 3.
