ABSTRACT:
For the controllable removal of bulk materials from containers, a device is provided with a gas-permeable lining facing the bulk material, which lining is mounted on a support under the container outlet, with a gas connection mounted on the support, and with a shut-off device or valve element. To achieve uniform material flow from the outlet without high expense for mechanical devices with the smallest possible structural dimensions, even for bulk materials with poor ability to flow, according to the invention, the support (7) with the gas-permeable lining (9) attached to it is designed at least partly as a valve element (5) for the container outlet (3), and that the valve element (5) is movable while clearing the container outlet (3) at least partially. For example, when materials are batched with the new device from containers into subsequent containers, it is possible to empty scales in batches in the case of negative weighing, and a satisfactory transition from batchwise emptying of a container to a continuous material flow is guaranteed.
