Definitions
- the invention relates to a method and an apparatus for dissolving accumulations solidified in a container a bulk material, which is in the form of a powder or granular material in the one with a discharge opening provided container bunkered and discharged if necessary becomes.
- Containers for bunkering and discharging powdery or granular Bulk materials are generally known, the predominantly used containers with an in Direction of a discharge opening tapered Part and a discharge device arranged thereon are provided, which are opened as needed is closed. Appropriate means of dissolving the accumulations of material formed and solidified in the container are not in the known containers intended.
- the invention has for its object a method and to provide a device for carrying out the method, by means of which it is possible to be formed in a container Accumulations of the filled and solidified bulk goods to remove and dissolve gently, so that a largely continuous discharge of the material from the container without any quality-dependent change in the material is achieved becomes.
- the solution to the method that leads to the interior of the container at least one approximately in the axial direction the same oriented removal element is provided, which with a first end above and at a distance from the outlet opening arranged on the inside of the container and with the other second end with one in the area of the outlet opening arranged swivel link operatively connected while doing so is engaged with the bulk accumulation in such a way that due to a movement oriented around the vertical axis of the container the swivel member, the bulk accumulation by means of removal element moved relative to the inner wall of the container is crushed for the discharge.
