dosing system, dense phase conveyor system and process for feeding powdered cargo material

摘要

dosing system, dense phase conveyor system and process for feeding powdered cargo material. The present invention relates to a dispensing system for the constant, continuous, metered feeding of a light polydisperse particulate powder loading material from a feeding device (bsg) to a plurality of tubes. conveyors (fr1, fr2, fr3) to a downstream consumer. the dispensing system comprises at least two dispensing containers (db1, db2, db3) with in each case a discharge device (ae2 / 1, ae2 / 2, ae2 / 3), the discharge device ( ae2 / 1, ae2 / 2, ae2 / 3) comprises for each conveyor tube (fr1, fr2, fr3) a dust flow regulating device (fi1 / 1, fi2 / 1, fi3 / 2) associated with the same and terminating in said tube, and wherein a mass flow measuring probe (fic1, fic2, fic3) is disposed in each of the conveyor tubes (fr1, fr2, fr3), which is coupled with the regulating device flow rate (fi1 / 1, fi2 / 1, fi3 / 2), which terminates in the corresponding conveyor tube (fr1, fr2, fr3). In addition, the dispensing system has a pressure regulating device which is coupled with the pressure measuring devices (pi1 / 1, pi2 / 2, pi1 / 3) arranged on the discharge devices (ae2 / 1, ae2 / 2, ae2 / 3), and which controls a dispensing vessel pressure (pis2 / 1, pis2 / 2, pis 2/3), at least depending on a dispensing vessel fill level (lis1, lis2, lis3 ). in this case, filling the dispensing container (lys 1, lys 2, lys 3). In this case, a pump device (v) may be coupled to each of the dispensing containers (db1, db2, db3), which supplies the dispensing container (db1, db2, db3) with a pressure (pis2 / 1, pis2 / 2, pis 2/3), which is smaller than the power device (b, sg). The invention further discloses a dense phase conveyor system comprising the dosing system and a process for the constant, continuous, metered feeding of a lightweight polydisperse particulate powder loading material.
