Date Dec. 23, 1992.An arrangement is provided for discharging granular or disintegrated material from silos in predetermined quantities per unit of time. The discharge arrangement includes a rotatable disc (15) which is intended to be placed at the bottom of the silo (1) and which is provided with at least one radially extending channel. A discharge device (21) is rotatably arranged in the channel or in each channel and is provided with recesses for accommodating material in the silo and for moving this material to a position in which it can be discharged from the silo. The discharge device or devices (21) suitably has/have the form of a cylinder provided with axially or helically cut grooves, these grooves forming the aforementioned recesses. A pillar (3) extends centrally through the silo (1), from the disc (15) to an inlet opening (4) in the top of the silo (1). The center pillar (3) and/or the silo wall is provided with a counteracting structure which functions to prevent material in the silo from being entrained by rotation of the disc (15). According to one suitable embodiment, a circularly arranged pipe (25) is placed on top of the disc (15), concentrically with its axis of rotation. The pipe communicates with a heating medium source and is provided with heating medium outlets through which the medium is introduced to the material in the silo (1). |
