Abstract
An apparatus for filling a container with bulk material, in particular sand, comprises a storage container for the bulk material with a closable lid and an outlet, a metering device arranged beneath the storage container and a pneumatic feeding device arranged under the metering device for feeding the bulk material into the container to be filled with the aid of compressed air via a feed hose. The feeding device has an injector with a plurality of, preferably at least five, holes for the compressed air.
Claims19
An apparatus for filling a container with bulk material comprising:
- a storage container for bulk material with a closable lid and an outlet;
- a metering device beneath the storage container;
- a pneumatic feeding device beneath the metering device for feeding the bulk material into the storage container;
- a feed hose configured to fill the pneumatic feeding device with air;
- the pneumatic feeding device having an injector with one or more a plurality of holes for receiving compressed air, at least one of which is angularly displaced relative to a flow centerline
- a control device configured to activate the pneumatic feeding device over a predefined time interval after deactivation of the feeding of the bulk material to remove the bulk material from the feed hose;
- and
- a sensor inside the feeding device and connected to the control device, the sensor configured to detect flow of the bulk material through the feed hose,
- the sensor configured to provide output to the control device indicating flow of the bulk material, the control device configured to deactivate the pneumatic feeding device based on the output from the sensor.
