A device for handling bulk goods, comprising a container (1) with an inlet means (3) and an outlet means (5) arranged in a bottom region (6) thereof, said container (1) defining a volume (V1) communicating with said inlet means (3) and outlet means (5), and a gas unit (2) for introducing gas into the volume (V1) for applying a pressure above atmospheric prevailing therein and acting to discharge bulk goods in the volume (V1) via the outlet means (5). A bottom surface (7) is arranged at said bottom region (6) of the container (1), said bottom surface (7) having a gas-permeable portion (8). In connection with application of a pressure above atmospheric in the volume (V1), the gas unit (2) acts to introduce at least part of the gas into the volume (V1) through said portion (8) in order to counteract compression, caused by the pressure above atmospheric, of bulk goods in the volume (V1). The device is characterised in that said gas-permeable portion (8) covers essentially the entire bottom surface (7), and that the outlet means (5) comprises a non-return valve movable between an open and a closed position. The non-return valve is arranged to take its open position if the pressure prevailing in the volume (V1) exceeds the pressure prevailing in a discharge conduit connected to the outlet means (5). The invention also concerns a container (1) for bulk goods and a method for handling bulk goods. |
