摘要:
The present invention relates to a metering device and a dense phase conveying system for the dosed supply of a light bulk material from a supply device (B, SG) via conveying tubes (FR1, FR2, FR3) to a consumer. For this purpose, an airlock (S) has a delivery device (AE/S) having a dust flow regulation device (FI4), which opens into a metering container (DB), whose delivery device (AE/DB) comprises multiple dust flow regulation devices (FI1, FI2, FI3), which each open into one conveying tube (FR1, FR2, FR3). A pressure regulation device of the metering device is coupled for differential pressure regulations (PDC1-2, PDC3-R) to pressure measuring devices (PIS1, PI2) of the airlock (S) and the metering container (DB) and to pressure measuring devices (PIR, PI3) of the metering container delivery device (AE/DB) and the consumer, in order to control the metering container pressure (PI2) as a function of the second differential pressure regulation (PDC3-R). For a differential pressure control (PISA4-1) between supply device (B, SG) and airlock (S), the pressure regulation device is coupled to a pressure measuring device (PISA4) of the supply device (SG, B). The pressure regulation device controls the airlock pressure (PIS1) as a function of an airlock fill level (LIS/S) and the differential pressure control (PISA4-1) by actuating at least one suction device (V) connectable to the airlock (S). Furthermore, the present invention discloses a method using the dense phase conveying system having the metering device.
