Method for automatically loading a feed line with bulk material

摘要

Method for automatically loading feed line with bulk material in suction delivery system having feed line, loading point, reservoir, and at least one material separator arranged at distance to reservoir. Method includes selecting target value for air speed for area of loading point, wherein for area of loading point, minimum target value and maximum target value for air speed are empirically determined from feed line parameters related to feed line and material parameters related to bulk material and values are stored in database. Method includes measuring in area of loading point one of air speed and quantity serving for determination of air speed in feed line and sending target value and measured value of air speed to controller. Method includes controlling air speed to target value via suction capacity, and adding bulk material in metered manner in dependence upon measured value of air speed when target value is reached.

1. Method for automatically loading a feed line with bulk material in a suction delivery system having the feed line, a loading location, a reservoir, and at least one material separator arranged at a distance to the reservoir, the method comprising:
selecting a target value for an air speed for an area of the loading location, wherein for the area of the loading location, a minimum target value and a maximum target value for the air speed are empirically determined from feed line parameters related to the feed line and from material parameters related to the bulk material, and the minimum target value and the maximum target value are stored in a database; measuring in the area of the loading location one of the air speed and a quantity serving for determination of the air speed in the feed line; sending the target value and the measured value of the air speed to a controller; controlling the air speed to the target value via a suction capacity using the controller; and opening an actuatable metering aperture to add the bulk material in a metered manner in dependence upon the measured value of the air speed when the target value is reached.
