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 (F14), 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, P12) of the airlock (S) and the metering container (DB) and to pressure measuring devices (PIR, P13) 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.

The present invention relates to a metering system for the steady, continuous, dosed supply of a bulk material in powder form made of light, polydisperse particles from a supply device (B, SG) into a plurality of conveying tubes (FR1, FR2, FR3) to a consumer arranged downstream. The metering system comprises at least two metering containers (DB1, DB2, DB3) each having a delivery device (AE2/1, AE2/2, AE2/3), the delivery device (AE2/1, AE2/2, AE2/3) for each of the conveying tubes (FR1, FR2, FR3) comprising a dust flow regulation device (FI1/1, FI2/1, FI3/2), which is assigned thereto and opens therein, and a mass flow measuring probe (FIC1, FIC2, FIC3) being arranged on each of the conveying tubes (FR1, FR2, FR3), which is coupled to the dust flow regulation device (FI1/1 to FI3/2) which opens into the corresponding conveying tube (FR1, FR2, FR3). Furthermore, the metering system has a pressure regulation device, which is coupled to the pressure measuring devices (PI1/1, PI1/2, PI1/3) arranged on the delivery devices (AE2/1, AE2/2, AE2/3), and which controls a metering container pressure (PIS2/1, PIS2/2, PIS2/3) at least as a function of a metering container fill level (LIS1, LIS2, LIS3). A pump device (V) can be coupled to each of the metering containers (DB1, DB2, DB3), which provides a pressure (PIS2/1, PIS2/2, PIS2/3) in the metering container (DB1, DB2, DB3), which is less than a pressure in the supply device (B, SG). Furthermore, the invention discloses a dense phase conveying system, which comprises the metering system and a method for the steady, continuous, dosed supply of a bulk material in powder form made of light, polydisperse particles.

摘要:
A carriage body for a rail vehicle, in particular for a high-speed train, said carriage body having a base and lateral walls that extend upwards on opposing sides of the base. The base and the lateral walls delimit an interior of the carriage body for transporting persons and/or goods. A longitudinal support for transmitting longitudinal forces is located in each transitional region between the base and the lateral walls, said longitudinal support extending in the longitudinal direction of the carriage body. The carriage body has at least one undercarriage support that extends below the base from the one longitudinal support to the other longitudinal support, said undercarriage support extending partly at a distance to the base so that a space for receiving at least one device for operating the rail vehicle is formed between the undercarriage support and the base.
